Abstract

The clinical efficacy of transcatheter atrial septal defect (ASD) closure with the Amplatzer Septal Occluder (ASO) can only be judged against the results of contemporaneous surgery. The present study compared early and late results of ASD closure using ASO versus open-heart surgery. Forty-eight adult patients were found eligible for transcatheter closure in transesophageal echocardiography. The surgical group consisted of 52 patients with isolated ostium secundum ASD. All patients underwent standard ECG, 24-hour ECG recording, and transthoracic echocardiography pre-procedure at 1-month and at 1-year follow-up. Physical fitness was assessed by cardiopulmonary exercise testing (CPX) prior to ASD closure and at 1-year follow-up. ASD closure was successful in all surgical patients and in 94% of the ASO group (0% mortality). The total complication rate for surgical vs. device closure was not significantly different (19.2% vs. 26.7%; p=0.383), despite more serious complications in the surgical group. Hospital stay was significantly shorter in the ASO group (5.4+/-2.2 vs. 9.1+/-1.2 days; p<0.001). Although echocardiographic parameters did not differ significantly between the respective groups at 1-year follow-up, CPX revealed a higher...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.
