Patients undergoing transcatheter aortic valve replacement (TAVR) often have concomitant coronary artery disease (CAD) which may adversely affect prognosis. There is uncertainty about the benefits and the optimal timing of revascularization for such patients. There is currently clinical equipoise regarding the management of concomitant CAD in patients undergoing TAVR. Some centers perform routine revascularization with percutaneous coronary intervention (PCI) (either before or after TAVR), while others follow an alternative strategy of medical management. The potential benefits and optimal timing of PCI in these patients are unknown. As TAVR expands to lower risk patients, and potentially becomes the preferred therapy for the majority of patients with severe aortic stenosis, the optimal management of concomitant coronary artery disease will be of increasing importance. The COMPLETE TAVR study will determine whether, on a background of guideline-directed medical therapy, a strategy of complete revascularization involving staged PCI using drug eluting stents to treat all suitable coronary artery lesions is superior to a strategy of medical therapy alone in reducing the composite outcome of Cardiovascular Death, new Myocardial Infarction, Ischemia-driven Revascularization or Hospitalization for Unstable Angina or Heart Failure. The study will be a randomized, multicenter, open-label trial with blinded adjudication of outcomes. Patients will be screened and consented for elective transfemoral TAVR and randomized within 96 hours of successful balloon expandable TAVR. Complete Revascularization: Staged PCI using third generation drug eluting stents to treat all suitable coronary artery lesions in vessels that are at least 2.5 mm in diameter and that are amenable to treatment with PCI and have a ≥70% visual angiographic diameter stenosis. Staged PCI can occur any time from 1 to 45 days post successful transfemoral TAVR. Vs. Medical Therapy Alone: No further revascularization of coronary artery lesions. All patients, regardless of randomized treatment allocation, will receive guideline-directed medical therapy consisting of risk factor modification and use of evidence-based therapies. The COMPLETE TAVR study will help address the current lack of evidence in this area. It will likely impact both the global delivery of health care and the management and clinical outcomes of all patients undergoing TAVR with concomitant CAD.

This is a longitudinal study where individual with Major Depressive Disorder (MDD) will be monitored for 12 weeks. The study aims to develop an objective, sensor-based, algorithm able to detect the presence of depression as well as predict treatment response. Measurement-based treatment is considered optimal and the development of a valid passive, objective, behavioral and biological assessment of depressive symptoms that does not rely on clinician interviews will improve monitoring and ultimately improve treatment significantly.

During breast surgery, sensory nerves are cut which may lead to reduced sensation and pain. Surgical reinnervation techniques have been developed with the aim of improving postoperative sensation by preserving the nerves and connecting them to the nipple and areola. The investigators aim to compare postoperative sensation and patient reported outcomes in patients undergoing reinnervation versus those not undergoing reinnervation to determine if there is a difference. The investigators will investigate this in patients undergoing gender-affirming mastectomy, implant-based breast reconstruction and autologous breast reconstruction. The investigators will use various tools that measure sensation quantitatively.

Machine perfusion technology is nearing the point of rescuing discarded liver grafts in the hope of proving them to be or improving them to the point of being transplantable. However, there are no validated metrics to determine transplantability after machine perfusion. This study involves collecting biopsies from transplanted livers before and after implantation to correlate metabolite and gene expression with post-transplant function. This data will help develop a viability index for machine perfused livers.
