One anatomic variant of pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals (PA/VSD/MAPCAs) is characterized by the absence of intrapericardial pulmonary arteries. This anatomy obviates the possibility of incorporating the pulmonary arteries for reconstruction or palliative procedures. The purpose of this study was to evaluate the surgical results in patients undergoing repair of PA/VSD/MAPCAs with absent pulmonary arteries. ⋯ The majority of patients with PA/VSD/MAPCAs and absent pulmonary arteries can undergo complete single-stage repair with satisfactory postoperative hemodynamics. These results suggest that unifocalization of MAPCAs can provide a reasonable pulmonary vascular bed in the absence of intrapericardial pulmonary arteries.

Repair Type Influences Mode of Pulmonary Vein Stenosis in Total Anomalous Pulmonary Venous Drainage.
We hypothesized that primary sutureless (SL) repair of total anomalous pulmonary venous drainage (TAPVD) may have a lower incidence of postrepair pulmonary vein obstruction (PVO) and different modes of PVO compared with standard repair (SR). ⋯ Primary SL appeared to be associated with a lower incidence and severity of PVO. The primary SL repair eliminated the risk of developing central PVO, although a relatively benign type of peripheral PVO could occur.

In order to improve our understanding of the evidence-based literature supporting temperature management during adult cardiopulmonary bypass, The Society of Thoracic Surgeons, the Society of Cardiovascular Anesthesiology and the American Society of ExtraCorporeal Technology tasked the authors to conduct a review of the peer-reviewed literature, including: 1) optimal site for temperature monitoring, 2) avoidance of hyperthermia, 3) peak cooling temperature gradient and cooling rate, and 4) peak warming temperature gradient and rewarming rate. Authors adopted the American College of Cardiology/American Heart Association method for development clinical practice guidelines, and arrived at the following recommendations: No Recommendation No recommendation for a guideline is provided concerning optimal temperature for weaning from CPB due to insufficient published evidence.

Right Minithoracotomy Versus Median Sternotomy for Mitral Valve Surgery: A Propensity Matched Study.
The efficacy of conventional median sternotomy versus a right minithoracotomy (RT) approach to mitral valve surgery was evaluated in a single high-volume institution. ⋯ Right minithoracotomy compared with median sternotomy for mitral valve surgery was associated with less postoperative atrial fibrillation, respiratory complications, acute renal failure, chest tube output, and use of packed red blood cells. Given study limitations, the RT approach for mitral valve surgery may have advantages over median sternotomy in selected patients.
