Coronary Artery Disease Clinical Trial
Official title:
Coronary Physiology Peri-Transcatheter Left-sided Valvular Interventions in Patients With Severe Aortic Stenosis or Mitral Regurgitation
Prospective, single-arm, observational study with invasive coronary physiology measurements before and after transcatheter left-sided valvular intervention.
The POTUS study is a prospective, investigator-initiated, single-arm observational study with invasive measurements that will consist of two cohorts. The first cohort consists of 120 patients with intermediate coronary artery disease who undergo a transcatheter aortic valve implantation (TAVI) for severe aortic valve stenosis ('TAVI cohort'). The second cohort consists of 30 patients with intermediate coronary artery disease who undergo transcatheter mitral valve repair (TMVr) for functional/degenerative mitral regurgitation ('TMVr cohort'). Both cohorts will undergo a battery of coronary physiological tests both before and after the valvular intervention. Additionally, in the case that the fractional flow reserve (FFR) over a coronary lesion is significant (i.e. FFR ≤ 0.80) during the post valvular intervention measurements, additional percutaneous coronary intervention (PCI) will take place during the same procedure. ;
