I have a particular interest in treating patients with high risk and complex coronary artery disease. This includes patients with low ejection fraction, calcified arteries, and completely blocked arteries (CHIP - complex high risk and indicated procedures; CTO - chronic total occlusions). I treat patients with aortic and mitral heart valve disease with procedures such as aortic valvuloplasty, mitral valvuloplasty, and transcatheter aortic valve replacement.
