Subacute left ventricular free wall rupture following acute myocardial infarction: bedside hemodynamics, differential diagnosis, and treatment.
Six patients with subacute left ventricular free wall rupture (anatomically proved) following acute myocardial infarction are presented. Diagnosis of cardiac rupture in every case was suspected several hours before death or surgical intervention, when clinical and hemodynamic data of cardiac tamponade were found. In three patients right atrial pressure decreased with inspiration and in the other three cases it did not show any modification. These latter three patients had associated right ventricular infarction; the abnormal respiratory behavior could be explained by restriction produced by a noncompliant right ventricle. All six patients improved initially with medical treatment (inotropics and fluid infusion) and three of them were operated upon. One of the latter patients died on the eighteenth postoperative day of extracardiac causes and two are long-term survivors.
