Abstract

From January 1966 through December 1985, 29 adolescents and adults underwent surgical repair of a partial atrioventricular septal defect at our institution. The patients included 20 females and 9 males, whose ages ranged from 16 to 47 years (mean, 27.6 +/- 10.1 years). Preoperatively, 24 patients were in New York Heart Association functional class I or II, and 5 were in class III. The pulmonary artery systolic pressure ranged from 22 to 62 mmHg (mean, 38.3 +/- 12.7 mmHg). The pulmonary-to-systemic flow ratio ranged from 1.4 to 2.9 (mean, 2.3 +/- 0.5). Upon left ventriculography, regurgitation through the left atrioventricular valve was trivial or nonexistent in 4 patients (13.8%), mild in 14 (48.3%), moderate in 10 (34.5%), and severe in 1 patient (3.4%). All patients underwent patch closure of the ostium primum defect, and all but 2 underwent partial or complete suturing of the septal commissure. One patient died within 30 days, for a hospital mortality of 3.4%. The follow-up period ranged from 7 to 25 years (mean, 15.2 +/- 5.3 years). Postoperatively, all patients were evaluated with 2-dimensional and Doppler echocardiography. One patient underwent early implantation of a permanent pacemaker for persistent complete heart bloc...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.

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.

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.
