Although increasing age has been associated with greater risk of mortality for patients undergoing mitral valve replacement, it is less clear whether this elevated risk is related to age-related differences in comorbidity or other clinical characteristics. ⋯ Operative mortality and morbidity rise with increasing age of patients undergoing mitral valve replacement. Although this excess risk is partially a result of increased comorbid burden and other operative factors, age remains an independent powerful risk factor for operative risk for mitral valve replacement. Understanding the relationship of age with other risk factors for mitral valve replacement can help stratify risk, enabling physicians to identify lower risk patients.

Hypothermic cardiopulmonary bypass with circulatory arrest is an important adjunct for operations on the distal aortic arch, the descending thoracic, and the thoracoabdominal aorta. The safety and efficacy of this technique when compared with other adjuncts (ie, simple aortic clamping, partial cardiopulmonary bypass, regional hypothermia) is not clearly established. ⋯ Hypothermic cardiopulmonary bypass with circulatory arrest provides safe and substantial protection against paralysis and renal, cardiac, and visceral organ system failure that equals or exceeds that of other currently used techniques but without the need of other adjuncts.

Comparative Study
Routine immediate extubation for off-pump coronary artery bypass grafting without thoracic epidural analgesia.
The expansion of coronary surgery on the beating heart without cardiopulmonary bypass has led to increasing interest in ultra-fast track anesthesia, allowing extubation of the patient in the operating theater. The techniques described to date combined general anesthesia with thoracic epidural analgesia. We report the routine application of a technique that allows immediate extubation in the majority of patients undergoing off-pump coronary artery bypass grafting without thoracic epidural analgesia. ⋯ Immediate extubation is possible in most patients after off-pump coronary artery bypass grafting even without thoracic epidural analgesia. We believe this type of less invasive cardiac anesthesia is safe and promising.

Comparative Study
Surgical coronary revascularization and antiarrhythmic therapy in survivors of out-of-hospital cardiac arrest.
Patients who survive out-of-hospital cardiac arrest are at high risk for recurrent arrest. Coronary artery bypass grafting (CABG) confers a survival advantage, but it is unclear whether antiarrhythmic drugs or an implanted defibrillator confer added benefit. This study was designed to determine predictors for further treatment, survival, and therapeutic internal cardiac defibrillator (ICD) discharge in this patient population. ⋯ Patients with coronary artery disease anatomically suitable for CABG who survive an acute out-of-hospital cardiac arrest should undergo EP testing after CABG. Approximately half of these patients are adequately treated by CABG alone. The remainder may benefit from ICD placement or medical antiarrhythmic management.

Ruptured sinus of Valsalva aneurysm (RSVA) is relatively common in oriental patients. We retrospectively analyzed 67 patients receiving repair of RSVA in a Beijing hospital over 5 years. ⋯ In this relatively high-risk population, repair of RSVA can be achieved with satisfactory early results.
