Limited Cumulative Experience with Ex-vivo Lung Perfusion is Associated with Inferior Outcomes After Lung Transplantation.
Ex vivo lung perfusion (EVLP) allows for prolonged preservation and evaluation/resuscitation of donor lungs. We evaluated the influence of center experience with EVLP on lung transplant outcomes. ⋯ The use of EVLP in lung transplantation remains limited. Increasing cumulative EVLP experience is associated with improved outcomes of lung transplantation using EVLP-perfused allografts.

Isolated mitral valve endocarditis: Patient, disease, and surgical factors that influence outcomes.
The objectives of this study were to investigate patient characteristics, valve pathology, bacteriology, and surgical techniques related to outcome of patients who underwent surgery for isolated native (NVE) or prosthetic (PVE) mitral valve endocarditis. ⋯ A patient- and pathology-tailored approach to surgery for isolated mitral valve endocarditis has low mortality and excellent results. Apparent superiority of standard valve repair is related to patient characteristics and pathology. Renal failure is the most powerful risk factor. In case of extensive destruction, extended repair shows no benefit over replacement.

A New Insight into Super Acute Care for Type A Acute Aortic Dissection in the Tokyo Acute Aortic Super Network.
To determine the status of type A acute aortic dissection using the Tokyo Acute Aortic Super Network. ⋯ This study demonstrated current practices in the emergency care of type A acute aortic dissection via the Tokyo Acute Aortic Super Network system, specifically a high rate of untreatable or inoperable cases and favorable outcomes in patients undergoing surgical treatment. High mortality rates were observed during the super acute phase after symptom onset or hospital arrival.

Comparing the patency of the left internal mammary in single, sequential, and y grafts.
To maximize arterial grafts, left internal mammary (LIMA) sequential and Y grafts are used. The aim is to compare the angiographic patency of the LIMA in these configurations. ⋯ Single grafts have the best patency. Failure in sequential grafts leads to increased occlusion of the LIMA inflow, whereas Y-graft failure tends to occlude the y limb. When arterial conduit is sparse, a Y graft should be considered.

Mitochondrial Transplantation Preserves Myocardial Function and Viability in Pediatric and Neonatal Donation After Circulatory Death Pig Hearts.
Mitochondrial transplantation has been shown to preserve myocardial function and viability in adult porcine hearts donated after circulatory death (DCD) . Herein, we investigate the efficacy of mitochondrial transplantation for the preservation of myocardial function and viability in neonatal and pediatric porcine DCD heart donation. ⋯ Mitochondrial transplantation in neonatal and pediatric pig DCD heart donation significantly enhances the preservation of myocardial function and viability and mitigates against damage secondary to extended WIT.
