Three Surgical Cases of Postinfarction Left Ventricular Free Wall Rupture / 日本心臓血管外科学会雑誌

ABSTRACT

Three surgical cases of postinfarction left ventricular free wall rupture (LVFWR) are described. Patient 1, a 76-year-old woman, developed LVFWR of the posterior wall after acute myocardial infarction (AMI). Coronary arteriography (CAG) revealed total occlusion of left circumflex artery (Cx) (#11). Direct closure of the myocardial tear was performed using cardiopulmonary bypass (CPB) and cardiac arrest. Patient 2, a 67-year-old man, developed LVFWR of the anterior wall after AMI. CAG revealed total occlusion of left anterior descending artery (LAD) (#7). He was placed on a percutaneous cardiopulmonary support system (POPS) prior to the operation and direct closure of the myocardial tear was performed with the heart beating. Patient 3, a 57-year-old man, developed LVFWR of the posterior wall after AMI. CAG revealed total occlusion of Cx (#13). He was placed on PCPS prior to the operation and direct closure of the myocardial tear was performed using CPB and cardiac arrest. Patients 2 and 3 who were placed on PCPS prior to the operation successfully underwent emergency operations. In all cases, 2-0 Prolene horizontal mattress sutures with Teflon felt strips were used through the infarcted area in order to close the myocardial tear.
