Right atrial myxoma: unusual clinical presentation and atypical glandular histology.
A 57-year-old black female presented with a 1-month of right-sided congestive heart failure and clinical evidence of pulmonic and tricuspid valvular stenosis and insufficiency. The echocardiographic examination and ventriculography demonstrated a large right atrial tumor interfering with the function of both right-sided valves. The patient underwent successful surgical resection of the tumor. Histologically, the tumor had cellular areas typical of myxoma, as well as glandular areas, a feature which has been described very rarely in this lesion. Electron microscopy of the glandular zones, which has never been reported previously, shown cells having essential homology with the usual myxoma elements. The atypical histopathology of this lesion supports the theory that atrial myxomas are true neoplasms, and are not derived from unusually organized mural thrombi.

Tricuspid valve operations in 530 patients. Twenty-five-year assessment of early and late phase events.
From Jan. 1, 1961, through Dec. 31, 1987, 530 patients underwent an intracardiac operation that included a tricuspid valve procedure. The tricuspid valve was repaired in 351 patients (66%) and replaced in 179 (34%). Mean age was 56.9 years. Risk factors associated with tricuspid valve replacement included tricuspid stenosis (p = 0.02), jugular venous distention (p = 0.04), previous operation (p = 0.05), and angiographic severity of tricuspid valve incompetence (p less than 0.001). There were 78 hospital deaths (15%). Risk factors for hospital death included previous operation (p = 0.03), male gender (p = 0.03), hepatomegaly (p = 0.03), De Vega or Carpentier annuloplasty (repair group only), (p = 0.01), and older age at operation (p = 0.06). Ninety-eight percent of the patients were followed up. There were 185 late deaths (41%). The actuarial survival rate was 20% at 180 months. Risk factors for late death included male gender (p = 0.03), hepatomegaly (p = 0.04), and lack of postoperative warfarin therapy (p less than 0.001). Actuarial freedom from reoperation was 25.5% at 180 months. There was no difference in reoperation rates (p = 0.10) or survival (p = 0.42) whether the tricuspid valve had been repaired or replaced. We conclude that the requirement for surgical treatment of tricuspid valve insufficiency in patients with multivalvular disease constitutes a high risk group for cardiac surgery. Preoperative variables may predict the result of tricuspid valve replacement. Tricuspid valve replacement may be performed with the expectation of a low risk of valve-related events.

Tricuspid valve repair for Ebstein's anomaly in young children: a 30-year experience.
BACKGROUND: The purpose of this study was to examine early and late outcome of tricuspid valve repair for Ebstein's anomaly in young children. METHODS: Between October 1974 and November 2003, 52 children (25 boys) underwent tricuspid valve repair and annuloplasty for Ebstein's anomaly. Mean age was 7.1 +/- 3.9 years (range, 5 months to 12 years). Concomitant procedures included atrial septal defect closure (n = 46), division of accessory conduction pathways (n = 4), ventricular septal defect closure (n = 3), and other (n = 7). RESULTS: Early mortality was 5.8% (3 of 52 patients; no mortality since 1984, n = 31). Risk factors were age younger than 2.5 years (p = 0.03) and weight less than 10.7 kg (p = 0.03). Morbidity included transient atrial (n = 11) and ventricular arrhythmias (n = 5), and early reoperation in 3 patients. There was no need for a permanent pacemaker. Mean follow-up was 12.2 +/- 7.4 years (maximum, 24.3 years). Actuarial survival at 5, 10, and 15 years was 92.3% +/- 3.7%, 89.9% +/- 4.3%, and 89.9% +/- 4.3%, respectively. Freedom from all reoperations at 5, 10, and 15 years was 91.0% +/- 4.3%, 76.9% +/- 6.8%, and 61.4% +/- 8.8%, respectively. Moderate (grade II) or more tricuspid regurgitation on dismissal echocardiogram was the only risk factor for reoperation (p = 0.04). Tricuspid stenosis did not occur in any patient. At late follow-up, 89% of patients were in New York Heart Association class I or II. CONCLUSIONS: Ebstein's anomaly in young children can now be repaired with low mortality and good tricuspid valve durability. Tricuspid regurgitation at the completion of operation should be mild or less to minimize need for reoperation. Tricuspid valve repair and annuloplasty did not result in stenosis despite somatic growth. Most patients enjoy an excellent quality of life.

Clinical spectrum of chronic rheumatic heart disease in India.
BACKGROUND AND AIM OF THE STUDY: The study aim was to determine prevalence and patterns of chronic rheumatic heart disease (RHD) in developing countries, where it remains a major cause of mortality and morbidity. The incidence of different valvular lesions and complications in chronic RHD were analyzed. METHODS: The study design was a retrospective case series analysis in the setting of a tertiary care institution in southern India. Participants were consecutive patients registered under 'chronic RHD' in the cardiology department of the authors' institution over the past 20 years. Data are presented for 10,000 cases in two age groups: group I, aged < or = 18 years (n = 2,910); and group II, aged > 18 years (n = 7,090). RESULTS: Mitral regurgitation was the single most common lesion (n = 1,007) in group I, while the dominant lesion in group II was mitral stenosis (n = 2,943). Isolated aortic valve disease was seen in 130 (4.5%) and 195 (2.8%) cases in groups I and II, respectively. Tricuspid stenosis was seen in 45 cases, and rheumatic involvement of all four cardiac valves was documented in four cases. Pulmonary hypertension was present in 42.4% and 80.8% in groups I and II, respectively, and functional tricuspid regurgitation in 38.9% and 77.2%, respectively. Overall, 5.9% of patients had atrial fibrillation, 0.9% had left atrial thrombus (seen on transthoracic echocardiography) and 0.4% had embolic cerebrovascular events. Pericardial effusion was present in 0.7% cases, and infective endocarditis was noted at presentation in 0.6%. CONCLUSION: Chronic RHD in developing countries is associated with major complications and high mortality. The critical evaluation of individual lesions must be combined with frequent overall clinical evaluation in order to time appropriate medical and surgical interventions.

Tricuspid inflow and regurgitant flow dynamics after mitral valve replacement: differences relating to surgical repair of the tricuspid valve.
BACKGROUND AND AIMS OF THE STUDY: Changes in tricuspid inflow and regurgitant flow dynamics were evaluated in patients with functional tricuspid regurgitation (TR) who underwent mitral valve replacement (MVR) with and without tricuspid annuloplasty (TAP). METHODS: In a group of 30 patients, all with atrial fibrillation, 15 underwent TAP performed according to the modified De Vega technique; the remaining 15 did not undergo TAP. Patients were studied before and serially after surgery, using pulsed and color Doppler echocardiography. The mean follow up was 4.7 years in the TAP group and 5.1 years in the non-TAP group. RESULTS: In the TAP group, immediately after surgery, the area of the TR jet decreased markedly, and the deceleration time of the tricuspid inflow velocity wave was significantly prolonged compared with that before surgery. By contrast, in the non-TAP group, both the area of the TR jet and deceleration time of tricuspid inflow velocity were virtually unchanged. The area of the TR jet remained small for a long period in the TAP group, but in non-TAP patients was increased in four cases over seven years, with two patients developing right-sided heart failure. Recent data showed the area of the TR jet to be significantly smaller, with maximum tricuspid inflow velocity significantly increased, and deceleration time of the tricuspid inflow velocity wave significantly prolonged in the TAP group compared with the non-TAP group. CONCLUSIONS: In patients with functional tricuspid regurgitation undergoing MVR, concomitant TAP may cause mild tricuspid stenosis, but produces sustained preventive effects against TR. Careful follow up is needed in patients who have not undergone TAP, as TR is not markedly decreased and may even be exacerbated. Aggressive TAP is recommended in patients showing dilatation of the tricuspid annulus, even if TR is mild.

Double balloon technique for dilation of valvular or vessel stenosis in congenital and acquired heart disease.
Despite the generally excellent success with balloon dilation for the stenotic lesions of congenital and acquired heart disease, technical difficulties sometimes prevent satisfactory results. Such technical difficulties include: a large diameter of the anulus of the stenotic lesion relative to available balloon diameter, difficulty in the insertion or removal of the larger balloon catheters, and permanent damage to or obstruction of the femoral vessels by the redundant deflated balloon material of the large balloons. A double balloon technique was initiated to resolve these difficulties. With this method, percutaneous balloon angioplasty catheters were inserted in right and left femoral vessels, placed side by side across the stenotic lesion and inflated simultaneously. Dilation procedures using the two balloon technique were performed in 41 patients: 18 with pulmonary valve stenosis, 14 with aortic valve stenosis, 5 with mitral valve stenosis, 3 with vena caval obstruction following the Mustard or Senning procedure and 1 with tricuspid valve stenosis. Patient ages ranged from 1 to 75 years (mean 17.8) and patient weights ranged from 8.9 to 89 kg (mean 42.3). Balloon catheter sizes ranged from 10 to 20 mm in diameter. Average maximal pressure gradient in mm Hg before dilation was 61 in pulmonary stenosis, 68 in aortic stenosis, 21 in mitral stenosis, 12 in tricuspid stenosis and 25 in vena caval stenosis. Average maximal valvular pressure gradient after dilation was 13 in pulmonary stenosis, 24 in aortic stenosis, 4 in mitral stenosis, 0 in tricuspid stenosis, and 1 in vena caval stenosis. No major complications were encountered with the procedures.(ABSTRACT TRUNCATED AT 250 WORDS)

Bidirectional cavopulmonary anastomosis with intracardiac repair.
BACKGROUND: Patients with hypoplasia of the right ventricle and tricuspid valve have historically undergone a total cavopulmonary connection or a two-ventricle repair with atrial fenestration. METHODS: We reviewed our experience with 9 patients with hypoplasia of the right ventricle and tricuspid valve who underwent a bidirectional cavopulmonary anastomosis with intracardiac repair. Patient diagnoses included pulmonary atresia with intact ventricular septum (n = 3); hypoplastic right ventricle and tricuspid valve with atrial septal defect, ventricular septal defect, and right ventricular outflow tract obstruction (n = 3); unbalanced atrioventricular canal defect (n = 1); inlet ventricular septal defect with coarctation (n = 1); and tricuspid stenosis with atrial septal defect (n = 1). RESULTS: The median age at operation was 36 months. There was hypoplasia of the right ventricle and tricuspid valve in all patients. The tricuspid valve measured 56.5% of normal (range, 43.6% to 70.4%) by echocardiography, and the median ratio of the tricuspid valve to the mitral valve was 0.67 (range, 0.54 to 0.82). At operation, the median tricuspid valve annulus diameter was 65.6% of published autopsy normals (range, 57.8% to 78.5%) with a median Z value of -3.8 (range, -6.6 to -2.1). All patients survived operation. At a median follow-up of 16 months, 5 patients are asymptomatic, and 2 have occasional early-morning periorbital edema. Two patients are on a regimen of diuretics, 1 of whom is also taking an unloading agent. The patient with unbalanced atrioventricular canal died suddenly at home 6 months postoperatively. CONCLUSIONS: Bidirectional cavopulmonary anastomosis with intracardiac repair may avoid the long-term complications associated with the Fontan modifications and eliminates the need of atrial fenestration in most instances. This operation should be considered for select patients with hypoplasia of the right ventricle and tricuspid valve.

Balloon valvuloplasty.
Percutaneous balloon valvuloplasty has been used for several years for the treatment of stenosis of all four cardiac valves. It has been particularly effective in pulmonary stenosis in children and in rheumatic mitral stenosis, especially in the younger age groups without severe calcification. After initial enthusiasm, results have not been as good in severe calcific aortic stenosis, although there is a place for aortic valvuloplasty in patients who are truly inoperable for reasons of age or coexisting disease. The procedure also may be applicable to occasional cases of tricuspid stenosis. The techniques used and results obtained with these procedures at Indiana University are described.

Clinical classification of Ebstein's anomaly.
Twenty-six patients with Ebstein's anomaly were classified into three types according to their clinical features, heart catheterization data, angiocardiographic and anatomical findings which were obtained on surgery or autopsy. The hemodynamics in each type were discussed. 1. Tricuspid Stenosis Dominant Type. Eight patients, who were cyanotic and had severe symptoms, mild to moderate cardiomegaly, and the "double-ball sign" on angiocardiography were classified into this type. A pressure gradient across the tricuspid valve was demonstrated in 5 patients. 2. Tricuspid Insufficiency Dominant Type. Four cyanotic patients, who had mild symptoms despite the severe cardiomegaly were grouped into this type. The "double-ball sign" was found in all. In three patients, incompetent tricuspid valve was observed. Tricuspid insufficiency necessitates the volume overwork of the right atrium and the functioning right ventricle, resulting in severe dilatation. 3. Mild Type. Fourteen patients who showed no or mild cyanosis, no or mild symptoms, and mild to moderate cardiomegaly, were classified into this type. It is considered that the adequate cardiac output in these patients is attributable to the good function of the tricuspid valve.

[Parachute tricuspid valve associated with Fallot's tetralogy].
Parachute deformity of the tricuspid valve was observed with a severe form of Fallot's Tetralogy with pulmonary atresia in a newborn. Signs of tricuspid stenosis (peripheral oedema, right atrial dilatation, hepatomegaly and conduction defects) were associated with the clinical signs of the principal malformation (severe hypoxaemia). To our knowledge, this is the first reported case of parachute deformity of the tricuspid valve.

Secundum atrial septal defect before and after surgery.
Twenty patients with secundum atrial septal defect, who had undergone open heart surgery were studied retrospectively. Girls were more affected than boys; the sex ratio was 1.5:1. Associated cardiac defects were diagnosed in two patients, one with moderate valvular pulmonic stenosis and the other one with small ventricular septal defect. Typical clinical findings consisted of loud first heart sound, widely fixed split second heart sound and soft ejection systolic murmur at the upper left sternal border were heard in all cases. Mid diastolic murmur due to relative tricuspid stenosis was detected in most cases (75%). Electrocardiographic findings included right axis deviation, prolonged PR-interval and right atrial enlargement were found in 50%, 15% and 60% of cases, respectively. Incomplete right bundle branch block and right ventricular enlargement were found in all cases, as was cardiomegaly with increased vascular markings were found in all cases. Paradoxical ventricular septal motion and visualization of the atrial septal defect were seen in 95% and 75% of cases, respectively. Cardiac catheterization was performed in 19 patients (95%). The pulmonary-systemic flow ratio (Qp/Qs) ranged from 1.7 to 6.3 (mean 2.9 +/- 0.67), and was correlated to the presence of mid diastolic tricuspid flow murmur and paradoxical ventricular septal motion. Simple closure of the defect was the procedure of choice, but in one patient (5%) pericardial patch was used to close the very large defect. The mortality rate was 10 per cent. Physical retardation was found in all boys and 50% of girls, before surgery. Body weight percentile increased in most cases (61.1%), while body height percentile increased in only 5.6% of cases, postoperatively. Ejection systolic murmur at the upper left sternal border was still detected in one patient (5.6%). Incomplete right bundle branch block persisted in all cases, while cardiomegaly was still found in 5.6% of cases followed-up six months to five years after surgery. There was no residual left ventricular dysfunction in all cases.

[Congenital heart defects: single ventricle with pulmonary valve stenosis and malposition of the great blood vessels].
A case of two: 21 years and 39 years old male patients with congenital heart disease: Single Ventricle with pulmonary valve stenosis and L-malposition of the great vessels. In the first case the diagnosis of congenital pulmonic stenosis & tricuspid regurgitation was established after birth and during the previous period. In the second case the diagnosis of VSD was established during the recruiting checkup, when he was 18 years old. Detailed non-invasive cardiologic examination was performed (transthoracic & transoesophageal echocardiography) and the diagnosis of Single Ventricle with pulmonary valve stenosis & L-malposition of the great vessels: Double-Inlet Left Ventricle with severe symptoms (21 years old & supraventricular paroxysmal tachycardia) with middle symptoms (39 years old) were established in both cases.

A new surgical approach to tricuspid annuloplasty: possibility of an extracardial suture technique "AV-gathering".
A new extracardiac method of annuloplasty for tricuspid insufficiency was performed on cadavers and in dogs. This procedure effectively produced valvular ring cerclage without causing any decrease in right coronary arterial blood flow. In the animal model, using this approach experimental tricuspid stenosis was successfully attempted. The details of the procedure are reported in this article.

[Valvulo-and annuloplasty in correction of complete atrioventricular septal defect].
The surgical and postoperative long-term results were assessed in 55 patients undergoing correction of complete atrioventricular septal defects. The patients was divided into two groups according to mode of plasty of the atrioventricular valve: 45 patients in whom the cleft was closed in the earlier series, and 10 with trifoliated mitral valve, leaving the cleft unclosed in the later series. The early death occurred in 13 of 45 patients in the earlier series and none in the later series. During 11 years follow up period, mitral valve regurgitation of grade 3 and 4 was observed in 20% of the patients, respectively, in the earlier series. In contrast, grade 3 mitral regurgitation was detected in only one and no grade 4 regurgitation was present in the later series. Tricuspid valve regurgitation was irrelevant. In the later series, the diameter of the mitral valve was greater than the average value of Rowlatt's standard by 3.4 mm after partisioning the common atrioventricular valve into mitral and tricuspid components, and smaller than the normal by 0.2 mm, though the diameter was within the normal range after valvulo-and annuloplasty. On the other hand, the diameter of the tricuspid valve was also greater than the normal value by 1.7 mm after partisioning, however, that was smaller than the normal by 1.7 mm after valvulo-and annuloplasty, on the average. The diameter was smaller than the normal lower limit by one standard deviation in two patients. There was present neither mitral nor tricuspid stenosis in all on the post-operative hemodynamic study.(ABSTRACT TRUNCATED AT 250 WORDS)

Right heart flow dynamics after tricuspid valve annuloplasty. Characteristics and time course.
To evaluate the effect of tricuspid annuloplasty (TAP) on right heart flow dynamics, we analyzed tricuspid inflow velocity pattern, jugular venous pulse and color Doppler flow signal of tricuspid regurgitation (TR) before and after surgery in 16 patients who underwent TAP (TAP group). Cardiac rhythm was atrial fibrillation in all patients. Twelve patients with lone atrial fibrillation served as controls (AF group). Patients in the TAP group were studied before and serially after surgery with a mean follow-up period of 2.7 years. TAP was performed according to the modified De Vega technique in all patients. In a comparison of the most recent data in the TAP group and the data in the AF group, the maximum tricuspid inflow velocity was significantly increased, and both the deceleration time of the tricuspid inflow velocity wave and the y-h interval of the jugular venous pulse were significantly prolonged in the TAP group compared to the AF group. Immediately after surgery, in the TAP group, the area of the TR jet was markedly decreased, and the deceleration time of the tricuspid inflow velocity wave was significantly prolonged compared to those before surgery. The area of the TR jet was dramatically decreased and remained small during the follow-up period. Thus, TAP may produce mild tricuspid stenosis but may also confer sustained preventive effects against TR.
