Cardiologic aspects of aortic valve surgery--who? when? what?

Israel Journal of Medical Sciences

Abstract

The title invites a discussion of a patient (age, lesion, physical condition, compliance, and other organ pathology) with aortic valve disease in the context of proposed surgical management. It further seeks clarification on the timing of such surgical contribution and on which operation is optimal. Without reviewing all the vast and somewhat conflicting literature, these aspects are addressed by a clinical cardiologist based principally on his own experience. Among the principal conclusions are the following: a) Surgery can safely be delayed in hemodynamically significant congenital aortic stenosis in children or young adults provided that the patients are nearly asymptomatic and that submaximal or maximal stress testing shows minimal or no ST-T changes. b) Prognosis after successful valve surgery for critically tight aortic stenosis in middle-aged and elderly patients differs from that for aortic regurgitation in that left ventricular myocardial dysfunction, however severe, will always improve postoperatively in the former condition. There is, therefore, never a cardiac contraindication to surgical management of symptomatic patients with tight aortic stenosis. c) Certain features in cases of chronic severe aortic regurgitatio...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
