AbstractA left ventricular (LV) free wall rupture is a highly lethal condition. A 78-year-old female, who collapsed while riding a bike, was admitted to our emergency service 7 days after experiencing chest pain. During admission, she had cardiopulmonary arrest. Though cardiopulmonary resuscitation was successful, computed tomography (CT) showed cardiac tamponade. Emergency surgery was then performed. Pericardiotomy revealed a postinfarction blowout rupture of an aneurysm (2 × 3 × 1 cm) on the anterolateral wall of the LV. The top of the aneurysm had a 2-mm wide blowing blood column. Intra-aortic balloon pumping was initiated. An off-pump multilayered sutureless repair using squares of collagen fleece with fibrinogen-based impregnation (i.e., TachoComb) and gelatin-resorcin-formalin glue (GRF glue) was performed. Postoperative coronary angiography revealed occlusion of the second diagonal branch. The patient was free from re-rupture or aneurysm enlargement. An LV blowout rupture, which was caused by myocardial infarction with a limited tear and necrotic area at the second diagonal branch territory, was successfully treated with an off-pump multilayered sutureless repair by using a TachoComb and GRF glue patch. The thickness of the hemostatic material seemed to help control the bulging of the aneurysm and to prevent further LV aneurysm enlargement and re-rupture.
