Transcatheter closure of atrial septal defects with the STARFlex device: early results and follow-up.

BACKGROUND: The STARFlex (SF) device is a CardioSEAL (CS) double-umbrella device that has been modified by the addition of a self-centering mechanism comprised of nitinol springs connected between the two umbrellas and a flexible core wire with a pin-pivoting connection. This paper compares the results of atrial septal defect (ASD) closure with CardioSEAL and STARFlex devices. PATIENTS AND METHODS: Between December 1996 and March 2000, 117 patients underwent ASD closure with CardioSEAL (n = 79) and STARFlex (n = 38). The mean age (17 years), weight (49 kg), and ASD size (15 mm) were similar in the two groups. The procedures were performed under general anesthesia with both fluoroscopic and transesophageal echocardiographic monitoring. IMMEDIATE RESULTS: The devices were successfully implanted in all patients. Ten patients had multiple ASDs. A single device was used in four patients (CardioSEAL in three, STARFlex in one), while a simultaneous placement of two CardioSEAL (one patient) or two STARFlex (five patients) were performed in six patients. The results are summarized as follows: [table: see text] Follow-Up Results: On follow-up clinical exam, electrocardiograms, chest X-rays, and echocardiograms were obtained at 1, 6, and 12 months. [table: see text] During follow-up there were no deaths, endocarditis, rhythm disturbances, or other complications. Arm fractures were observed almost exclusively with large CardioSEAL devices (40 mm, less frequently with 33 mm), and only in one 33-mm STARFlex device. There were no clinical complications related to fractures. CONCLUSIONS: The STARFlex device seems to offer better results than the CardioSEAL, with significantly lower rates of residual shunts and arm fractures.

Lack of effects of recombinant human growth hormone in a child with a complex cardiovascular malformation and dilated cardiomyopathy.

Recent studies have suggested the beneficial effects of GH treatment in patients with dilated cardiomyopathy. We have treated with recombinant human growth hormone (rhGH) a 6-year-old female with a complex congenital heart defect (severe tricuspid hypoplasia and malposition of the great arteries), who developed a progressive dilated cardiomyopathy of unknown etiology. rhGH treatment (0,1 U/kg/day, for 3 months) did not improve cardiac function, nor clinical symptoms, although we have no clear explanations for this. However, a trial with rhGH may be offered to children with dilated cardiomyopathy and waiting for heart transplantation.

Rapid reversal of dilated cardiomyopathy following removal of neuroblastoma.

Reported is a child with dilated cardiomyopathy, in whom medical therapy resulted in a mild improvement of cardiac function. Metabolic studies suggested the presence of a catecholamine-secreting tumour; and an adrenal neuroblastoma was identified and surgically removed. Following surgery, there was progressive and complete normalization of cardiac function. Although very rare, neurogenic tumours may be involved in the development of a dilated cardiomyopathy in the infant and child.

Mechanical valves in the pulmonary position: a reappraisal.

OBJECTIVES: To evaluate midterm results of mechanical valves in pulmonary position in patients with pulmonary regurgitation and right ventricular dysfunction as an alternative to bioprostheses. PATIENTS: Mechanical valves (six tilting disc valves and two bileaflet valves) were implanted in eight patients previously operated on for tetralogy of Fallot (n = 7) and truncus arteriosus (n = 1), with severe right ventricular dysfunction caused by massive pulmonary regurgitation. RESULTS: All patients survived prosthesis implantation and are currently well. At follow-up (3 months to 9 years), they do not show signs of valve failure, and right ventricular function has dramatically improved in all but one, who still shows moderate ventricular hypokinesia. CONCLUSION: After operative correction of congenital heart defects in selected patients who show severe dysfunction of the right ventricle caused by pulmonary regurgitation/stenosis, mechanical valves may represent an alternative to bioprosthetic valves. The selection of the valve type is still a matter of debate. However, according to literature data, complications seem to have occurred only in patients with bileaflet mechanical valves in the pulmonary position, whereas no thromboembolic episodes or valve failure is reported in subjects with tilting disc valves in the right ventricular outflow. Tilting disc valves might perform better in the right ventricular outflow than bileaflet valves.

[Percutaneous closure of interatrial defect using the buttoned double-disk prosthesis].

BACKGROUND: Surgical repair is the procedure of choice for atrial septal defect correction. Even though surgical mortality is low (< 1%), morbidity is significant (anesthesia, thoracotomy, cardiopulmonary bypass, longer hospitalization and intensive care unit monitoring). Transcatheter methods to occlude atrial septal defects have been in development during the last two decades. We report our experience in Italy with the Sideris buttoned double-disk device. METHODS: From March 1992 to April 1993, 14 patients aged 20 months to 52 years, weight 10 to 82 kg, underwent transcatheter atrial septal defect occlusion with the Sideris buttoned device. The buttoned device is a miniaturized two disk device introduced through small venous sheaths (8-9 F). The diameter of atrial septal defects by echocardiography varied between 9 and 23 mm, while the balloon stretched diameter of the defects varied between 13 and 24 mm. The devices selected were 19 +/- 4 mm larger than the stretched diameter of the defect, but less than the total length of the septum (33-56 mm) by echo. RESULTS: Pulmonary-to-systemic flow ratio varied between 1.5 to 4.0. Mean pulmonary artery pressure varied between 10 and 24 mmHg (mean value 17 +/- 3.5 mm Hg). The relationship between different atrial septal defect measurements (echo, shunt flow, stretched diameter) was statistically analysed: transthoracic echo diameter had a good correlation with the balloon stretched diameter (r = 0.63, p < 0.001). The atrial septal defect was occluded in 12 patients (86% success rate). There was one early "unbuttoning" which was surgically corrected with success. The other patient underwent surgical correction 3 months later because of unsuitability for transcatheter closure. Minimal residual shunt detected by color flow mapping at 1 month follow-up was seen in 4 patients (33%). No complications occurred in any of our patients. CONCLUSIONS: This initial experience with the Sideris buttoned double-disk device demonstrated that transcatheter closure of atrial septal defect is feasible and effective. It can be accomplished through small introducing sheaths. Further clinical trials are justified. This method could become the procedure of choice for the correction of small ASDs.

Infundibular septal defect with severe aortic regurgitation: a new surgical approach.

Aortic regurgitation associated with prolapse of an aortic cusp and an infundibular septal defect is caused by the lack of anatomical support for the aortic annulus by the conal septum. This fact is taken into consideration in the new surgical approach that we performed in 5 children 3 to 16 years of age with infundibular ventricular septal defect and severe aortic regurgitation. The ventricular septal defect is closed by a patch anchored to another patch through the prolapsed cusp. This second patch is pulled up with the prolapsed cusp and is then fixed in the aortic wall. In all 5 patients, all clinical signs of aortic insufficiency disappeared, and only minimal aortic regurgitation could be demonstrated by color Doppler mapping.

Aortopulmonary window coexisting with tetralogy of Fallot: echocardiographic diagnosis.

Aortopulmonary window coexisting with tetralogy of Fallot (TF) was prospectively diagnosed by two-dimensional (2D) echocardiography and Doppler in an 18-month-old boy; the diagnosis was confirmed by cardiac catheterization and angiocardiography. Surgical correction was performed, but the patient died in the operating room from right ventricular dysfunction. The autopsy showed an adequate surgical repair, but the histologic examination of the lungs demonstrated severe pulmonary vascular disease, which was presumed to be the cause of death.

[Total anomalous pulmonary venous drainage: is a surgical correction possible on the sole basis of echocardiography?].

Between April '83 and August '89, 33 patients with total anomalous pulmonary venous drainage were studied at the department of Cardiology in Bergamo. There were 18 males and 15 females, aged between three days and 8 months (average: two months). In this study only cases of isolated total anomalous pulmonary venous drainage were taken into consideration. The patients underwent echocardiographic examination with ATL MK 600, Vingmed 700, ATL Ultramark 9 with 3.5; 5; 7.5; MHz transducers; in the last three years the echocardiographic examination was integrated by continuous and pulsed wave Doppler and, in the last year, by color Doppler. The morphologic diagnosis was routinely established by means of the sequential approach method. A common feature in all types of total anomalous pulmonary venous drainage was the impossibility of defining the connections of the pulmonary veins with the left atrium. Furthermore, patients had a volume overload of the right heart, and atrial septal defects of various sizes. The site of anomalous drainage of the pulmonary veins was assessed by means of multiple cuts from subcostal, precordial and suprasternal windows. The echocardiographic diagnosis was exact and complete in 29 cases (87.9%), and in four cases it was incomplete but basically correct (12.1%). The anatomical findings were confirmed during cardiac surgery in 32 cases and by autopsy in one case of supracardiac total anomalous pulmonary venous drainage in a critically ill patient, who died before surgery. Of the 32 patients who underwent surgical correction, 20 (62.5%) had only an echocardiographic diagnosis, which resulted correct in all cases. The majority of patients with isolated TAPVD can be confidently diagnosed by means of echocardiography, thus, avoiding preoperative catheterization.

[Abdominal lymphoma with abscess and thoracic perforation: en-bloc resection].

The authors compare a rare case of acute onset Gastric Lymphoma with that present in the literature. The patient, a white 67 year-old man, was admitted to hospital in severe general condition. On CT scan an opacity of the pleura and a subtotal collapse of the left lung associated with a mass infiltrating the diaphragm, the gastric fundus and pancreas were seen. After 48 hours from the admission an operation was performed. The abdominal mass infiltrating the stomach, the spleen and the left thorax was resected en-bloc by laparotomy. A Boulau drainage was inserted. The histology showed an high malignant, diffused, big cell lymphoma. The patient was discharged 23 days later after a regular postoperative course. Surgery can be necessary, sometime curative in gastric lymphomas while long term result and quality of life could be improved by chemotherapy.

[Primary anastomosis in the neoplastic colonic obstruction].

The authors report their own experience on the treatment of large bowel obstruction caused by a neoplastic stenosis. During a 36-month period 110 operations for emergency large bowel obstructions were performed: 59 (53.6%) underwent primary anastomosis without colostomy (28 right colectomy, 16 left colectomy, 9 sub-total and 6 total colectomy). Total group post-operative mortality was 2.9% as a result of cardio-pulmonary complications. Morbidity was 19.8%, included a 3% of anastomotic leak underwent surgical treatment. Our results suggest that resection and primary anastomosis can be performed with acceptable morbidity and mortality in a high proportion of cases of emergency large bowel obstructions.

[The surgical treatment of fixed aortic subvalvular stenosis].

Over the past 5 years, 45 patients (11 adults and 33 children) have undergone operations for discrete and fixed subaortic stenosis. The resection of the subvalvular membrane or the fibromuscular collar was the procedure of choice. 28 patients underwent myectomy and/or myotomy. None patients died during operations. No significant symptoms and gradients remained after operation. We conclude that in the surgical management of fixed discrete subaortic stenosis myectomy and myotomy in addition to membranectomy produces better relief of the left ventricular outflow obstruction than do membranectomy alone.
