Abstract

There are an increasing number of elderly patients with critical aortic stenosis. This study was performed to evaluate the surgical outcome of aortic valve surgery for elderly patients with aortic stenosis. Eleven patients aged over 75 years old (mean 79.7 +/- 4.4) underwent aortic valve replacement with stented bioprosthesis from May 2001 to August 2004. All of the patients had a history of congestive heart failure, syncope, or angina pectoris with multiple medical problems including renal dysfunction, diabetes mellitus, cerebral infarction, or coronary artery disease. The New York Heart Association (NYHA) classification ranged II to IV (mean 2.8 +/- 0.7). Their logistic Euro score ranged from 2.56 to 41.61 (mean 8.6 +/- 10.9). The concomitant procedures were annular enlargement in 2 and coronary artery bypass grafting (CABG) in 3 patients. All patients tolerated these procedures well and were discharged except 1 patient who died from arrhythmia on the postoperative day 14. Postoperative echocardiogram after 3 months showed satisfactory decrease in peak left ventricular-aortic pressure gradient as well as left ventricular mass regression. All surviving patients are in NYHA class I. Aortic valve replacement provided satisfactor...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.
