l Coronary artery bypass grafting for patients with ischemic left ventricular dysfunction (ILVD) remains superior to medical therapy in terms of long-term survival. Recently, off-pump coronary artery bypass surgery has been shown to be very promising in achieving functional improvements with favorable operative mortality in this challenging group of patients. The aim of this study was to assess the risk factors responsible for operative mortality in this group of patients. ⋯ This study showed that using cardiopulmonary bypass for multivessel coronary artery bypass grafting in patients with ILVD was not proved to act as an independent predictor of operative mortality.

Anomalous coronary artery origin from the pulmonary artery: correlation between surgical timing and left ventricular function recovery.
This study investigates the correlation between surgical timing and 15-year longitudinal left ventricular and mitral valve function, after repair of anomalous coronary artery origin from the pulmonary artery. ⋯ Repair of anomalous coronary artery origin from the pulmonary artery in younger symptomatic infants offers the best potential for recovery of left ventricular function, despite a worse initial presentation. Coronary transfer is associated with superior long-term survival and freedom from reoperation. Most patients with patent two-coronary repair will recover normal mitral valve function; therefore, simultaneous mitral valve surgery seems unwarranted.

Surgical treatment of a diffusely diseased coronary artery has been considered a relative contraindication for off-pump coronary artery bypass grafting. To our knowledge, long onlay-patch grafting with off-pump coronary artery bypass grafting has not been described. ⋯ We report our early experience with off-pump long onlay bypass grafting in patients with a diffusely diseased coronary artery using double Octopus tissue stabilizers.
