David M. Zlotnick, MD

I am an interventional cardiologist with UBMD Cardiovascular Medicine, with specialized training in echocardiography, nuclear cardiology and noninvasive vascular interpretation (RPVI). I see outpatients through the UBMD ambulatory practice at the Amherst Clinic, and I care for patients admitted to the Buffalo General Medical Center (BGMC) consultative service and BGMC’s Cardiac Care Unit (CCU). My interventional practice involves evaluating and caring for patients with coronary and structural heart diseases. I perform diagnostic coronary angiography, percutaneous coronary intervention (PCI), coronary atherectomy, percutaneous mechanical hemodynamic support, cardiac biopsy, patent foramen ovale (PFO)/atrial spetal defect (ASD) closure and transaortic valve replacement (TAVR).

I also have a specialized focus on evaluating and managing patients with peripheral vascular disease, including noninvasive vascular testing and endovascular interventions. I see patients at the Gates Vascular Institute (GVI) where I perform diagnostic peripheral and carotid angiography and interventions for peripheral arterial diseases. These procedures include lower extremity arterial atherectomy, angioplasty and stenting, renal and mesenteric artery revascularization and subclavian intervention.

I am active in research at the GVI by participating in a number clinical trials. One aims at protecting patients from renal damage during PCI (CARIN, Ischemix). Another involves an alternative procedure to perform TAVR for intermediate-risk patients with symptomatic aortic stenosis (SURTAVI, Medtronic). A third clinical trial addresses using intracoronary delivery of stem cells in patients postanterior myocardial infarction with ischemic left ventricular dysfunction (ALLSTAR, Capricor).

As a faculty member at the University at Buffalo, I teach and mentor residents and fellows during their hospital rotations.
