I'm curious :) what is it exactly? an aneurysm? a very thin ventricle wall during CHF or something? I'm curious what makes the wall so weak.
According to my source a blown out is a left ventrical wall rupture occurs in approximately 0.8–6.02% of patients after acute myocardial infarction. Autopsy studies have shown the incidence was more common in 16–21% of the hospitalized patients.
Several procedures of surgical repairs have been proposed, including use of sutures with pledgets, Dacron patch, and infarctectomy, as well as the use of biologically glued sutureless pericardial patches.
Thanks for the question. I hadn't heard of "blown left ventricle" before, and it must be an almost fatal event.
