Validation of the HeartMate 3 survival risk score in a large left ventricular assist device center.
The HeartMate 3 survival risk score was recently validated in the Multicenter study Of MagLev Technology in Patients Undergoing Mechanical Circulatory Support Therapy with HeartMate 3 to predict patient-specific survival in HeartMate 3 left ventricular assist device candidates. The HeartMate 3 survival risk score stratifies individuals into tertiles according to survival probability. ⋯ The unadjusted HeartMate 3 survival risk score was associated with postimplant survival in patients outside of the Multicenter study Of MagLev Technology in Patients Undergoing Mechanical Circulatory Support Therapy with HeartMate 3 but did not remain an independent predictor after adjusting for ischemic etiology and severe diabetes. The HeartMate 3 survival risk score was able to identify patients at high survival using a binary cutoff, but we were unable to demonstrate its discriminatory ability among the previously published risk tertiles.

Review Practice GuidelineThe 2024 American Association for Thoracic Surgery expert consensus document: Current standards in donor lung procurement and preservation.
Donor lung procurement and preservation is critical for lung transplantation success. Unfortunately, the large variability in techniques impacts organ utilization rates and transplantation outcomes. Compounding this variation, recent developments in cold static preservation and new technological advances with machine perfusion have increased the complexity of the procedure. The objective of the American Association for Thoracic Surgery (AATS) Clinical Practice Standards Committee (CPSC) expert panel was to make evidence-based recommendations for best practices in donor lung procurement and preservation based on review of the existing literature. ⋯ Consistent and best practices in donor lung procurement and preservation are critical to improve both lung transplantation numbers as well as recipient outcomes. The recommendations described here provide guidance for professionals involved in the care of patients with end-stage lung disease considered for transplantation.

Multicenter StudyLong-term outcomes after aortic root replacement for bicuspid aortic valve-associated aneurysm.
Patients with congenital bicuspid aortic valve often require root replacement. This study aims to describe their long-term rates of mortality and reoperation. ⋯ Patients who undergo aortic root replacement with bicuspid aortic valve have an increased rate of aortic reoperation (35%; 95% CI, 23%-46%) while their survival appears to be comparable to the general US population (79%; 95% CI, 73%-87%) at 15 years.

Multicenter StudyThe Cone repair Allows Right Ventricle Rehabilitation with Excellent Tricuspid Valve Function Following the Starnes Procedure.
We present a case series of right ventricle (RV) rehabilitation after the Starnes procedure in patients with Ebstein anomaly (EA), applying the Cone repair of the tricuspid valve (TV) to achieve 2-ventricle or 1.5-ventricle physiology. ⋯ After the Starnes procedure, the Cone repair allowed RV rehabilitation, resulting in trivial or mild TR at a midterm follow-up. The Starnes procedure is a reproducible technique that no longer commits patients to lifetime single-ventricle physiology.
