Ventricular Septal Perforation: A Rare but Life-Threatening Complication Associated with Takotsubo Syndrome.

A 71-year-old woman was admitted with dyspnea. An electrocardiogram revealed ST-segment elevation, and echocardiography showed akinesis in the left ventricular apex with hyperkinesis of the base. Coronary angiography revealed no stenosis, and left ventriculography indicated ballooning of the left ventricular apex and apical ventricular septal perforation.

Pseudoaneurysm developed after aortic root homograft implantation.

A 55-year-old man with severe infective endocarditis underwent aortic root replacement using a homograft concomitant with saphenous vein grafting to the left anterior descending artery. The patient developed angina due to stenosis of the proximal anastomosis of the vein graft accompanied by a 2-cm pseudoaneurysm. This complex lesion was successfully managed with urgent coronary artery bypass surgery through a left thoracotomy, followed by a redo replacement of the old aortic homograft.
