[Clinical demonstrations: Heart rupture in acute myocardial infarct. Infectious endocarditis. Wolff-Parkinson-White syndrome].
This clinical demonstration includes three topics of clinical cardiology: myocardial rupture in acute myocardial infarction, infective endocarditis, and WPW-syndrome with paroxysmal supraventricular tachycardia. In the first part three cases with septal perforation or papillary muscle rupture are demonstrated. Our experience with myocardial rupture (free wall, septum, papillary muscle) during the last six years is summarized with special reference to the significance and the differential diagnosis of systolic regurgitant murmurs after myocardial infarction. Special features of acute mitral incompetence (papillary muscle dysfunction) in myocardial infarction are outlined and diagnostic guidelines for differentiation between septal perforation and papillary muscle rupture are discussed. In the second part two patients with aortic (e.g. mitral) valve rupture in the course of infective endocarditis are presented. The synoptic comparison of these two patients is related to the results of our own clinical studies on the changing pattern of infective endocarditis (epidemiologically, clinically) during the last three decades. The clinical picture of acute aortic valve rupture is outlined and the bedside signs indicating catastrophic complications of infective endocarditis are summarized. In the third part the odyssey of a patient with WPW-syndrome and consecutive paroxysmal supraventricular tachycardia is described. Progress in electrophysiological analysis of the re-entry circles in preexcitation syndromes is outlined.
