Population-Based Analysis of Late Outcomes of Mitral Valve Repair for Degenerative Mitral Valve Regurgitation.

Background: Population-based analyses may reduce uncertainty related to referral bias and/or incomplete follow-up.

Objectives: This study analyzed long-term mortality and durability of mitral valve repair in a geographically defined population with clinical and echocardiographic follow-up.

Methods: We used the Rochester Epidemiology Project to identify 153 Olmsted County patients who underwent mitral valve repair for degenerative regurgitation from 1993 to 2018.

Methacrylate-based copolymers as tunable hosts for triplet-triplet annihilation upconversion.

The ability to convert light to higher energies through triplet-triplet annihilation upconversion (TTA-UC) is attractive for a range of applications including solar energy harvesting, bioimaging and anti-counterfeiting. Practical applications require integration of the TTA-UC chromophores within a suitable host, which leads to a compromise between the high upconversion efficiencies achievable in liquids and the durability of solids. Herein, we present a series of methacrylate copolymers as TTA-UC hosts, in which the glass transition temperature ( ), and hence upconversion efficiency can be tuned by varying the co-monomer ratios (-hexyl methacrylate (HMA) and 2,2,2-trifluoroethyl methacrylate (TFEMA)).

Short and Long-Term Outcomes of Lung Transplantation from Brain Death vs. Circulatory Death Donors: A Meta-analysis of Comparative Studies.

Objectives: To investigate through a meta-analysis of comparative studies the impact of donor type (brain death DBD vs circulatory death DCD) on the short- and long-term outcomes of lung transplantation(LTx).

Methods: Literature search (terms "lung transplantation" AND "donation after circulatory death") was performed up to July 2022 and studies comparing outcomes of LTx from DCD versus DBD were selected. Primary endpoints were early and long-term mortality.

Surgical management of giant cell arteritis of the proximal aorta.

Objective: Giant cell arteritis (GCA) may present as proximal aortic pathology requiring surgical intervention. We present our experience with surgical management of GCA in patients presenting with proximal aortic disease.

Methods: From January 1993 to May 2020, 184 adult patients were diagnosed with GCA on histopathology after undergoing cardiac surgery.

Is concomitant tricuspid valve repair in patients undergoing robotic mitral valve repair safe and effective?

Objectives: Robotic-assisted mitral valve repair (MVr) is a well-established procedure for management of degenerative mitral valve disease. Limited data regarding concomitant robotic-assisted tricuspid valve repair (TVr) is available. This review investigates prevalence and outcomes of concomitant robotic-assisted mitral and tricuspid valve repair.
