Abstract

To evaluate the efficacy of interventional therapy for complex congenital heart defects patients with un-repaired or postoperative residual lesions. Between March 1998 and April 2009, 42 patients (12 females), mean age 6 years (5 months to 30 years) received interventional therapy, 17 cases underwent occlusion of major aorto-pulmonary collateral arteries (MAPCAs), 15 underwent device closure of residual ventricular or atrial septal shunting, 12 underwent balloon angioplasty (n = 10) and stenting (n = 2) for stenosis of the anastomosis of vessels or branched pulmonary arteries. Twenty-three MAPCAs were performed in 17 patients without residual shunting. One patient died of multiple organ failure after intervention therapy and the remaining patients discharged without complication, successful device closure was performed in 15 patients and there was minimal residual shunting in 1 patient. There were no severe arrhythmias such as complete atrio-ventricular block during and post procedure. Exercise capacities were significantly improved in 12 patients underwent balloon angioplasty or stenting. Pressure gradients were significantly decreased and there was no aneurysmal or thromboembolic formation post procedure. Interventional thera...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.
