Objective: Mitral valve surgery (MVS) carries substantial risk of postoperative atrial fibrillation (PAF). Identifying patients who benefit from prophylactic left atrial appendage amputation (LAAA) or maze is ill-defined. To guide such interventions, we determined preoperative predictors of PAF and investigated 3-year survival of patients with PAF.

The model has not been prospectively tested in HeartMate 3 recipients.
Methods: A single-center HeartMate 3 cohort from July 2016 to July 2021 (n = 108) was utilized for this analysis.
Right heart failure after left ventricular assist device implantation: a persistent problem.
Indian J Thorac Cardiovasc Surg

Left ventricular assist device (LVAD) is an option for bridge-to-transplant or destination therapy for patients with end-stage heart failure. Right heart failure (RHF) remains a complication after LVAD implantation that portends high morbidity and mortality, despite advances in LVAD technology. Definitions of RHF vary, but generally include the need for inotropic or pulmonary vasodilator support, or potential right ventricular (RV) mechanical circulatory support.

- There is a growing need for accessible surgical simulation training in low-resource countries, prompting a pilot workshop at a new simulation center to evaluate low-cost training models.
- The workshop engaged local educators, who were trained using hybrid-fidelity simulation models created from inexpensive materials, effectively preparing them to teach essential clinical skills to anesthesiology trainees.
- Survey results indicated high satisfaction with the training models, with 100% ranking the pericardiocentesis simulator as "good" or "outstanding," highlighting the importance of collaboration to enhance surgical education in lower middle-income countries.
A 72-year-old patient presented with severe tricuspid regurgitation and patent foramen ovale (PFO) in the setting of severe mediastinal shifting after remote right pneumonectomy. Surgical approach was challenging given the significant herniation of the heart and left lung into the right hemithorax. This report describes tricuspid valve replacement with PFO closure via a right posterolateral thoracotomy and alternative cardiopulmonary bypass cannulation strategy.

Prior studies have reported worse mortality for patients with vascular complications on VA-ECMO; however, these were limited by small sample size. The purpose of this study is to investigate predictive risk factors for vascular complications in VA-ECMO patients and their potential impact on mortality.

There is a lack of information regarding the impact of trauma on POPF rates when compared with elective resection. We hypothesize that trauma will be a significant risk factor for the development of POPF following DP.
