Multicenter Study Comparative StudyMitral valve repair versus replacement for patients with preserved left ventricular function without heart failure symptoms.
The purposes of this study are to compare outcomes of mitral valve repair (MV-repair) and mitral valve replacement for patients with severe mitral regurgitation with preserved ventricular function and no congestive heart failure (CHF) symptoms and to examine variations in surgeon choice of procedure and outcomes by surgeon volume. ⋯ Patients with chronic severe primary mitral valve regurgitation with preserved ventricular function and no CHF symptoms who underwent MV-repair experienced lower mortality and no different reoperation, CHF, or stroke readmission rates than patients who underwent replacement. Greater-volume surgeons were more likely than their lower volume counterparts to choose mitral repair. Repair should be considered as the surgical option for these patients whenever possible.

Randomized Controlled TrialImpact of remote ischemic preconditioning preceding coronary artery bypass grafting on inducing neuroprotection.
Neurological complications after coronary artery bypass grafting (CABG) reduce quality of life, increase mortality, and inflate resource utilization. The risk of postoperative neurological complications parallels the increasing risk burden of the contemporary patient population. We evaluated the efficacy of remote ischemic preconditioning (RIPC) on inducing neuroprotection. ⋯ Silent brain ischemia occurs frequently after CABG. RIPC did not reduce the incidence of the primary outcome. However, RIPC significantly reduced the pooled volume of ischemic brain lesions. Surgery adversely affected global brain connectivity, with RIPC conferring no demonstrable protection. The association of RIPC with superior neurocognitive test scores failed to cross the threshold for significance.

Concomitant ablation of atrial fibrillation in rheumatic mitral valve surgery.
Efficacy of atrial fibrillation ablation in rheumatic mitral valve disease has been regarded inferior to that in nonrheumatic diseases. This study aimed to evaluate net clinical benefits by the addition of concomitant atrial fibrillation ablation in rheumatic mitral valve surgery. ⋯ Surgical atrial fibrillation ablation during rheumatic mitral valve surgery was associated with a lower risk of long-term mortality and thromboembolic events. Therefore, atrial fibrillation ablation for rheumatic mitral valve disease may be a reasonable option.

Surgical margins and risk of local recurrence after wedge resection of colorectal pulmonary metastases.
During resection of pulmonary metastases, the need to spare lung parenchyma is often weighed against the increased risk of local recurrence if an inadequate surgical margin is obtained. We sought to identify risk factors for local recurrence after wedge resection of pulmonary metastases of a colorectal origin. ⋯ Among surgically resected colorectal pulmonary metastases, technical factors related to margin length and tumor size were associated with the risk of local recurrence, whereas tumor grade and KRAS status were not. However, the increased risk of local recurrence with larger tumors was diminished with a sufficient margin length.
