Cardiac

This is a single-center, comparative, observational, retrospective data study. Datasets from patients who underwent spectral coronary CT angiography (CCTA) for suspected coronary artery disease (CAD) or other diagnosis needs as part of their routine clinical evaluation will be included.

The aim of this study is to compare the analgesic effects of ultrasound-guided bilateral erector spinae plane block versus ultrasound-guided bilateral combined Pecto-intercostal fascial plane block and recto-intercostal fascial plane block in patients undergoing cardiac surgery.

Blood flow restriction resistance exercise uses partial vascular occlusion of a limb during low weight resistance exercises to stimulate muscle strengthening and growth. This is commonly used during rehabilitation from an injury. Because blood flow in and out of the limbs is decreased, this may have consequences for blood flow through the heart. The purpose of this study will be to test cardiac dynamics during blood flow restriction resistance exercise to determine if cardiac blood flow is impacted. It is hypothesized that both non-BFR exercise and BFR exercise will increase heart rate shortening various cardiac cycle parameters, but BFR exercise will increase the isovolumetric contraction time vs non-BFR exercise due to an increase in total peripheral resistance. It is also hypothesized that BFR exercise will lower early ventricular filling parameters due to lower venous return.

This study aims to evaluate whether targeted video feedback generated by an artificial intelligence (AI)-based surgical performance assessment model can support improvement in technical skills among cardiac surgeons performing coronary artery bypass grafting (CABG). This is a single-group, self-controlled, pre-post interventional study. Participating surgeons will submit a baseline CABG surgical video, which will be assessed by both an AI model and blinded human expert raters using standardized scoring criteria. Based on the AI assessment, surgeons will receive personalized video feedback highlighting operative steps associated with lower technical performance. After a one-month self-directed review period, a follow-up CABG surgical video will be submitted and evaluated using the same process. Changes in human-rated technical skill scores between baseline and follow-up will be used to assess the potential educational impact of AI-generated video feedback.

This study it to evaluate the usability of the WearLinq eWave patch in a general adult population.
