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.

Two hundred and one consecutive patients with symptomatic
paroxysmal supraventricular tachycardia
(PSVT) underwent a diagnostic electrophysiological test and catheter ablation with radiofrequency (RF) current. In 102 (51%) patients, the mechanism of PSVT was found to be atrioventricular nodal reentry (AVNRT, typical in 101, atypical in 1). Atrioventricular reentrant tachycardia (AVRT) involving accessory pathway was present in 94 (47%) and ectopic atrial tachycardia in 5 patients. A successful outcome was achieved in 100 of 102 patients (98%) with AVNRT and in 85 of 94 patients (90%) with AVRT. The anatomical approach was used for ablation in patients with AVNRT. The focus was ablated in 4 patients with ectopic atrial tachycardia whereas it was modified in the remaining one patient. Procedure-related complications occurred in 4 patients (2 AVNRT, 2 AVRT). One patient each developed haemothorax, pericardial effusion, mitral valve
endocarditis
and high-grade AV block requiring permanent pacemaker implantation. The electrode and ablation catheters were repeatedly used after ethylene oxide sterilisation to reduce the cost of the procedure. RF ablation is an effective, safe and curative modality of treatment for patients with symptomatic PSVT due to AVNRT and AVRT. The experience with this modality in patients with ectopic atrial tachycardia is limited.
