Structural Cardiology
Our group has focused on prevention and treatment of valvular heart disease. Clinically, transcatheter valves have been offered at UCLA for aortic position (TAVR) since 2012 and for mitral position (Mitraclip) since 2015. With the clinical program, research projects have flourished from study prevention of disease to optimization of treatment techniques to novel valvular devices.
Several ongoing retrospective analyses are ongoing evaluating hemodynamic impact of intervention (TAVR or Mitraclip), optimization of conduction system during TAVR to lower risk of pacemaker, to aortic valve design for treatment of aortic valve regurgitation. In addition, we have been involved in multiple clinical trials for the TAVR procedure and enrolled patients over the years.
Ongoing Trials
- TAVR Unload: Use of TAVR in patients with moderate aortic stenosis and low LVEF
- CARILLON: Evaluating outcomes in functional mitral regurgitation with Carillon device.
- ENVISAGE-TAVI AF: Evaluation of edoxoban in patients with severe aortic stenosis and atrial fibrillation in the setting of TAVR
Upcoming Trials:
- COMPLETE TAVR: Impact of complete revascularization in patients who are treated with TAVR
- RESTORE: Use of Harpoon Device to treat mitral regurgitation
- ENCIRCLE: Use of M3 mitral valve replacement system to treat mitral regurgitation
