Patellar Tendon Reconstruction Using Tibialis Posterior Allograft for Treatment of Patellar Tendon Rupture After Bone-Patellar Tendon-Bone Anterior Cruciate Ligament Reconstruction.

Bone-patellar tendon-bone (BPTB) autografts are often used to treat anterior cruciate ligament (ACL) tears in young, highly active patients. These grafts are robust and provide adequate stability, allowing for return to sport and optimal functional outcomes in athletes. Patellar tendon rupture following BPTB ACL reconstruction is rare and can be difficult to treat.

Impact of institutional variables on centre performance in long-term survival after heart transplant.

Objectives: The gold standard metric for centre-level performance in orthotopic heart transplantation (OHT) is 1-year post-OHT survival. However, it is unclear whether centre performance at 1 year is predictive of longer-term outcomes. This study evaluated factors impacting longer-term centre-level performance in OHT.

Deep Learning-Based Automated Labeling of Coronary Segments for Structured Reporting of Coronary Computed Tomography Angiography in Accordance With Society of Cardiovascular Computed Tomography Guidelines.

Purpose: To evaluate a novel deep learning (DL)-based automated coronary labeling approach for structured reporting of coronary artery disease according to the guidelines of the Society of Cardiovascular Computed Tomography (CT) on coronary CT angiography (CCTA).

Patients And Methods: A retrospective cohort of 104 patients (60.3 ± 10.

Intravenous infusion of mesenchymal stem cells enhances regional perfusion and improves ventricular function in a porcine model of myocardial infarction.

Transplantation of stem cells may improve regional perfusion and post-infarct ventricular function, but the optimal dose and efficacy of cell delivery via the intravenous route has not been determined. This study tested the hypothesis that intravenous infusion of bone marrow-derived mesenchymal stem cells (MSCs) enhances regional perfusion and improves ventricular function after myocardial infarction. In a closed-chest pig model, the LAD coronary artery was occluded for 75 min by angioplasty balloon inflation followed by 12 weeks of reperfusion.
