Pulmonary atresia with intact ventricular septum: Intended strategies.
Neonatal interventional strategies for pulmonary atresia with intact ventricular septum are based on tricuspid valve hypoplasia and right ventricle-dependent coronary circulation. We sought to evaluate long-term outcomes comparing biventricular (BiV) versus single-ventricle (SV) strategies. ⋯ Pulmonary atresia with intact ventricular septum remains a challenging lesion for those patients on the SV pathway, particularly with right ventricle-dependent coronary circulation.

Late results after stand-alone surgical ablation for atrial fibrillation.
Stand-alone surgical ablation of atrial fibrillation is indicated in patients with refractory atrial fibrillation who have failed medical or catheter-based ablation. Few reports of late outcomes after stand-alone surgical ablation exist using comprehensive follow-up with strict definitions of success. This study examined our late outcomes of the stand-alone Cox-Maze IV procedure. ⋯ The stand-alone Cox-Maze IV had excellent late efficacy at maintaining sinus rhythm in patients with symptomatic, refractory atrial fibrillation, with low morbidity and no mortality. The Cox-Maze IV, in contrast to catheter-based ablation, was equally effective in patients with paroxysmal and nonparoxysmal atrial fibrillation.

Outcomes of pleurectomy decortication in patients with biphasic mesothelioma.
There are limited small, single-institution observational studies on the role of surgery in patients with biphasic mesothelioma. Herein we report a series of 147 consecutive patients with biphasic mesothelioma treated over 11 years in a high-volume single institution with intended pleurectomy decortication (PDC). ⋯ In selected patients with biphasic mesothelioma and good prognostic factors prolonged survival after PDC is expected.

Hybrid strategy in neonates with ductal-dependent systemic circulation and multiple risk factors.
The study objective was to analyze outcomes of the hybrid strategy for ductal-dependent systemic circulation consisting of bilateral pulmonary artery banding with or without ductal stenting followed by delayed Norwood-type palliation or comprehensive stage II operation in high-risk neonates. ⋯ High-risk neonates with hypoplastic left heart syndrome or its variants can be successfully palliated using the hybrid strategy and bridged to a delayed Norwood or comprehensive stage II operation with satisfactory survival. This operative approach is a promising alternative pathway for neonates deemed to be high risk due to multiple preoperative risk factors.

Mitral valve repair for isolated posterior mitral valve leaflet prolapse: The effect of respect and resect techniques on left ventricular function.
Posterior mitral valve leaflet prolapse repair can be performed by leaflet resection or chordal replacement techniques. The impact of these techniques on left ventricular function remains a topic of debate, considering the presumed better preservation of mitral-ventricular continuity when leaflet resection is avoided. We explored the effect of different posterior mitral valve leaflet repair techniques on postoperative left ventricular function. ⋯ Our study showed that both leaflet resection and chordal replacement repair techniques are effective at preserving postoperative left ventricular function in patients with posterior mitral valve leaflet prolapse and significant regurgitation.
