This study intends to provide a detailed overview of the types and rates of peri-operative complications after surgical correction of an isolated ASD II. The transvenous approach to the occlusion of atrial septal defects has yielded promising results during its first 5 years of clinical trials, but before it can be established as a routine measure, definite proof is needed to demonstrate that its rate of serious complications does at least not exceed that of the surgical closure. Between 1985 and 1992, 232 consecutive patients underwent surgical closure of a secundum atrial septal defect. Among the patients 118 were children (< 18 years; 79 girls and 39 boys) with a mean age of 8.9 +/- 5.2 years (4 months-17 years) and 114 adults (74 women and 40 men) with a mean age of 28.5 +/- 10.8 years (18-69 years). Pre-operatively eight children (6.8%) and eight adults (7%) were treated for right heart failure. Mean pulmonary artery pressure was 20.4 +/- 10.4 mmHg for the children and 19.3 +/- 7 mmHg for the adults. The average pulmonary artery to systemic flow ratios were 2.9:1 and 3:1 for children and adults, respectively. Thirty children (25.4%) and 15 adults (13.2%) underwent patch closure while direct suture was the method used for the remaining patients. Average cardiopulmonary bypass time was 35.7 +/- 17.9 min for the children and 41.5 +/- 19.9 min for the adults. The length of the procedure (skin to skin) was a mean of 116 min in the young group, and 141 min in the adult group.(ABSTRACT TRUNCATED AT 250 WORDS)

Long-term results of BA for discrete AC are excellent and should be considered as first option for treatment of this disease.

Our findings, and similar observations by others, suggest involvement of the sinus node and the distal conduction system in this form of the LQTS. Several histologic studies have documented abnormalities within the conduction system, including apoptosis. Because of the rare occurrence and poor prognosis of the LQTS with impaired AV conduction, international guidelines for diagnosis and treatment are needed. Development of an internal cardiac defibrillator for this young age group is necessary.

We describe what is, to the best of our knowledge, a previously unreported association in patients with similar facial features, skin and joint laxity, of lengthening and tortuosity of systemic, pulmonary and coronary vessels. We evaluated 12 patients with similar phenotypes, from eight different families. Detailed echocardiographic and angiographic evaluations were performed in all, and biopsies of the skin in seven. All patients have elongated facies, prominent ears, micrognathia and laxity of their joints. Angiographic pictures showed a varying degree of lengthening and tortuosity of systemic, pulmonary, and coronary arteries. Pulsatile carotid arteries formed cervical masses in 2 patients, and three had severe renal arterial stenoses. All showed varying degrees of branch and peripheral pulmonary arterial stenosis, necessitating placement of stents in six. Biopsy of the skin proved normal in all seven patients studied, thus excluding cutis laxa, Ehlers-Danlos and Marfan syndromes. The constellation of abnormalities suggests a genetic syndrome of connective tissue etiology. Further genetic studies, and gene mapping, are underway.

Transcatheter occlusion of the patent arterial duct using Gianturco coils is an effective and safe technique. In the learning curve there is a relatively high rate of inadvertent embolization, but the coils can be retrieved in the vast majority of patients. The complication rate is offset by the high early occlusion rate and the inexpensiveness of the procedure.

Fifty-one children with the initial attack of acute rheumatic fever (ARF) were studied prospectively to verify the sociodemographic and clinical profile and to compare results with those from other countries. Most children belonged to large families who lived in an urban setting with ready access to medical care. Unlike reports from many developing countries, the clinical manifestations in this study paralleled data from the West and included arthritis in 76% of the cases, carditis in 43%, and chorea in 8%. Among the 22 cases with carditis, 18 had mitral regurgitation, three developed combined mitral and aortic regurgitation, and one had aortic regurgitation. This study demonstrates the mild nature of ARF in Saudi Arabia and supports the concept that climate and geography appear to bear little relationship to the incidence and severity of ARF.

Aims: To assess the safety, efficacy, and long term results of mitral balloon valvotomy (MBV) for rheumatic mitral stenosis in children and adolescents in comparison to adults. Methods: The results of 468 patients with mitral stenosis who underwent successful MBV and were followed up for 0.5-13 years were analysed. Patients were divided according to age at the time of MBV into group 1 consisting of 84 patients ( 20 years of age (children and adolescents) and group 2 that included 384 patients, age . 20 (adults). , and similar complication rates, compared to group 2. After a mean follow up of 5 (3.5) years there was no significant difference between groups 1 and 2 in the incidence of restenosis (14.3% v 16.1%, NS). Event-free survival rates at 5, 10, and 12.5 years were 93%, 79%, and 79% for group 1 and 94%, 90%, and 84% for group 2 (p = 0.18). Conclusions: MBV is safe and effective in children and adolescents with rheumatic mitral stenosis. It provides better immediate results than in adults and excellent long term results that are comparable to those seen in adults.
