NCT03442400
Coronary artery blockages can reduce blood flow to the heart muscle. Fractional flow reserve (iFR or FFR) assessment is an invasive tool used to determine how much blood flow is reduced. The investigators will perform iFR/FFR on all intermediate coronary stenoses using standard practice, immediately before (at the time of) transcatheter aortic valve replacement (TAVR) and after successful TAVR. The investigators will compare pre- and post-TAVR iFR/FFR values, and assess short-term outcomes. The investigators hypothesize that iFR/FFR values will be consistently and significantly higher pre-TAVR in comparison with post-TAVR for the same lesions.
NCT04263376
This study is designed as a prospective pilot study for longitudinal assessment of fecal microbiome related to medical and surgical weight loss. The investigators follow the standard of care for perioperative and intraoperative management of study participants. The only addition to the standard of care protocol will be collection of fecal samples at 3 time points. This will enable investigators to compare changes in and effects by microbiota after low-calorie diet versus after bariatric surgery .
