Moderate hypothermia with ACP is associated with lower in-hospital and 30-day mortality, shorter cardiopulmonary bypass time, and fewer neurologic sequelae than deep hypothermia in patients who undergo aortic arch surgery with ACP.

Low-dose ASA use within 24 hours of CABG is independently associated with decreased early postoperative mortality.

Left atrial (LA) dissection is an uncommon entity that occurs most often after mitral valve surgery. We present a case of a 52-year-old man who developed an LA dissection after repair of a postinfarction left ventricular (LV) aneurysm. Transesophageal echocardiography was used to establish the diagnosis of an LA dissection that almost completely occluded the LA, limiting LV filling and causing hemodynamic instability.
