Abstract

This study reports the cases of 14 patients aged 5 months to 13 years (average: 3.5 years) at the time of the initial repair of an atrioventricular septal defect (AVSD). The AVSD was partial in 5 and complete in the other 9 cases. After failure of the initial mitral valvuloplasty, the patients underwent mitral valve replacement with a prosthesis at the age of 1 to 29 years, after an interval of 0 days to 15 years. A second valvuloplasty had been attempted in 3 cases beforehand. The aim of this paper was to analyse the causes of failure of mitral valvuloplasty and to determine the conditions of mitral valve replacement and the specific complications of this type of surgery. Failure of mitral valvuloplasty was related to complex valvular malformations (5 cases), technically inadequate valvuloplasty procedures (4 cases), deterioration of an initially satisfactory valvuloplasty (5 cases). Four bioprostheses were implanted (repeat valvular replacement was necessary in 3 patients). Early mortality was 28% (4 patients). The postoperative complications specific to this condition were: immediate atrioventricular block (8 cases) but only 1 persistant complete atrioventricular block; traumatic fistula between the left ventricle and right ...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
