Minor congenital variations of cusp size in tricuspid aortic valves. Possible link with isolated aortic stenosis.

Clinically isolated aortic stenosis is most commonly caused by a congenitally malformed aortic valve. Many elderly patients with isolated aortic stenosis have a tricuspid aortic valve. It has been suggested in the past that inequalities in individual cusp size could be a factor leading to the development of the stenoses in these cases. In this study the width and height of individual aortic valve cusps were measured at necropsy in 200 hearts of patients without clinical signs of aortic stenosis, though the majority of valves obtained from elderly persons showed some ageing changes. The results were compared with similar measurements in 16 hearts of patients with clinically diagnosed and necropsy proven isolated aortic stenosis. The results show that inequality in cusp size is the rule rather than the exception. Indeed, only 5 of the 200 'normal' tricuspid aortic valves had 3 cusps of identical height and width, and each of the 16 cases with isolated aortic stenosis has cusps of differing size. The results seem to contradict the aforementioned hypothesis. However, the striking similarities between isolated aortic stenosis and the ageing aortic valve, suggest that isolated tricuspid aortic stenosis is an extreme with a spectrum of ageing alterations. Inequality in cusp size, with differences in mechanical tissue stress as a consequence, could then play a role in the pathogenesis of the stenosis by accelerating the ageing process.

Balloon valvuloplasty for fungal endocarditis induced stenosis of a bioprosthetic tricuspid valve.

Palliative treatment was provided without complications by double balloon valvuloplasty of a stenotic porcine tricuspid valve in a patient with fungal endocarditis. With two 15 mm diameter valvulotomy balloons the peak tricuspid gradient decreased from 21 to 7 mm Hg and valve area increased from 0.3 to 1.2 cm2. After the procedure the patient clinically improved; however, valve replacement was not performed as planned because the patient developed an intracranial hemorrhage. She subsequently died of complications of fungemia. The present report demonstrates the possible use of valvuloplasty as a palliative procedure in selected patients with valvular stenosis involved with endocarditis.

Concurrent balloon dilatation of tricuspid and calcific mitral valve in a patient of rheumatic heart disease.

Concurrent percutaneous balloon dilatation of the mitral and tricuspid valve was performed in a 21-year-old female with severe rheumatic calcific mitral stenosis and severe tricuspid stenosis. The mean gradient across the mitral valve decreased from 30 mm Hg to an immediate post-dilatation level of 14 mm Hg and the mitral valve area increased from 0.71 cm2/m2 to 1.2 cm2/m2. The mean gradient across the tricuspid valve decreased from 11.5 mm Hg to 5 mm Hg. Hemodynamic improvement was maintained at a repeat study performed eight days later. Palliative balloon dilatation of two valves, concurrently performed, thus saved the patient from an open heart procedure and a possible valve replacement.

[Surgery for the valvular disease in children].

We report the results and long-term follow up in 34 children (17 girls and 17 boys, aged 12 days to 13 years, average age 3.3 years, average body weight 11.7 kg) who underwent valvular surgery in the period between May 1989 and November 1996. Operative mortality was 11.8%. Actuarial survival curves (including hospital mortality) indicate a 68.6% survival rate at 5 years and that 64.7% of patients are free from reoperation at 5 years. For aortic regurgitation two patients applied aortic valvuloplasty and four applied aortic valve replacement. Nine children had aortic stenosis, three of them had balloon valvuloplasty, seven had valvotomy, two had aortic valve replacement. Ten patients were treated for mitral regurgitation. There were nine valvuloplasty and four mitral valve replacement including three times of reoperation. One membranous pulmonary atresia and seven pulmonary stenosis children had valvotomy. There were four cases of tricuspid disease. One had tricuspid valve stenosis with pulmonary stenosis, three had severe tricuspid regurgitation who applied tricuspid valve replacement. Mortality was high in the critical AS, severe MR and TVR groups. Patients who survived the surgery and had no complications showed satisfiable results.

Tricuspid valve involvement in combined mitral and aortic valve surgery.

BACKGROUND: Combined mitral and aortic valve disease requiring surgery may involve the tricuspid valve as well. Our treatment policy is conservative especially for tricuspid regurgitation which is operated on when severe only. METHODS: A retrospective study was performed at a tertiary and secondary referral center for cardiovascular disease. Over a 15-year period, 65 consecutive patients underwent aortic and mitral surgery with concomitant tricuspid regurgitation and/or stenosis. Fifty-five/65 (85%) patients were in NYHA class III-IV. Fifty-eight/65 (89%) patients had tricuspid regurgitation secondary to right chamber dilatation and 7/65 (11%) had tricuspid stenosis and/or regurgitation because of previous endocarditis. Twenty-two/65 (34%) tricuspid valves were operated on: 18/22 (82%) de Vega annuloplasty, 2/22 (9%) commissurotomies and 2/22 (9%) prosthetic valves. Mortality and complications were recorded during a mean follow-up of 5.3 yrs (range, 6 months-15.3 yrs). Event-free survivals were determined using the Kaplan-Meier method. RESULTS: Hospital mortality was 6.2% (4/65) and the complication rate was 18.5% (12/65). The freedom from late valve related mortality and morbidity at 5, 10 and 15 years was 86+/-5.5%, 81.9+/-6.8%, and 81.9+/-6.8% respectively. One valve related complication was due to the tricuspid valve. At last follow-up, 87% (47/54) of the survivors were in NYHA class I-II. CONCLUSIONS: With a conservative policy of tricuspid valve intervention, functional results of this patient population are good and long-term valve related morbidity and mortality are mainly related to the mitral and aortic valve procedures.

Pulmonary artery catheterization: the right heart should not be left out--a case report.

Tricuspid valve stenosis in the setting of endocarditis is associated with a high morbidity. Diagnostic approaches incorporate a high clinical index of suspicion, echocardiographic evidence, and inferences about hemodynamic data derived from pulmonary artery catheterization. As demonstrated by the case presented herein, inadequate initial evaluation of right-sided pressures delayed the diagnosis and treatment of prosthetic tricuspid valve stenosis.

Cronic non-rheumatic valvular heart disease. An autopsy study.

The frequency of chronic non-rheumatic valvular heart disease in Iceland was investigated via autoposies performed from November 1965 through December 1974. During this period, about 12.400 Icelanders died at the age of 16 years and older and 28.8 per cent of these were included in the study. At autopsy, males outnumbered females by 2:1. The frequency of calcific aortic stenosis was found to be 3.63 per cent and the prevalence was calculated to be 3.17 per cent among males and 4.50 per cent among females. Calcific aortic stenosis in tricuspid valves was more frequent in females and calcific aortic stenosis in bicuspid valves was more frequent in males. Among the hearts with calcific aortic stenosis, 70.8 per cent were found to have normally tricuspid valves, 25.4 per cent bicuspid valves and 3.8 per cent tricuspid valves with an unicommissural fusion. In 0.59 per cent of the hearts the aortic valve was either bicuspid or had an uncommissural fusion without the features of calcific stenosis. However, a functional stenosis was suggested by the increased weight of most of these hearts. The frequency of bicuspid aortic valves was 1.2 per cent with a prevalence in males of 1.54 per cent and in females 0.50 per cent. A calcified mitral annulus was found in 1.98 per cent of the hearts and in most, it was either associated with calcific aortic stenosis in a tricuspid valve, or it was a single valvular disease. Rheumatic valvular disease was found in 1.08 per cent of the heart examined.

Immunological profile in congenital heart disease.

Fifty children with established congenital heart disease (CHD) were surveyed for the immune profile. Ventricular septal defect (VSD) was the commonest lesion (56%) followed by Tetralogy of Fallot (ToF; 16%), atrial septal defect (ASD; 8%), patent ductus arteriosus (PDA; 4%), transposition of great arteries (TGA; 4%), aortic stenosis (AS; 4%), and pulmonic stenosis (PS), tricuspid atresia (TA), single ventricle with pulmonic stenosis (SV with PS) and dextrocardia with ToF (2% each). Immunoglobulins (IgG, IgA and IgM) were estimated. IgG and IgA levels were significantly reduced in all children with congenital heart disease, whereas IgM levels were increased in cyanotic but unaffected in the acyanotic group. Complement C3 and C4 levels were reduced in all, more so in cyanotics. T-helper cells were decreased and T-suppressor cells were increased in all groups with congenital heart disease as compared to controls. B-cell percentage was increased in cyanotics but not affected in the acyanotics.

[Left valvular involvement in carcinoid: description of a case].

Right-sided valvular heart disease is a common complication of metastatic carcinoid tumors. On the contrary, left valve involvement is a rare finding. In our report we describe a patient in whom the subsequent involvement of right and left heart valves was documented by 2D and Doppler echocardiography. The patient was a 46-year-old woman who, in the last three years, complained of face flushing, postprandial diarrhea and shooting epigastric pain lasting for hours. She came at our observation for increasing dyspnoea, peripheral edemas and asthenia. 2D-echocardiography and Color Doppler revealed a severe tricuspid regurgitation and a turbulent blood flow across the pulmonary valve. An Angiographic examination confirmed the severe tricuspidal regurgitation and disclosed a mild pulmonary stenosis. These findings were associated with high 5 hydroxyndole acetic acid (5-HIAA) urinary excretion and the presence of a liver metastasizing ileal carcinoid tumor. Some months later, a new 2D echo-Doppler examination showed thickening and reduced motion of the posterior mitral leaflet, associated with regurgitation and an aortic insufficiency without evident structural valvular abnormalities. Even if carefully investigated no right-to-left shunt was found.
