Dr. Roy’s core practice involves complex coronary intervention, with keen interest for bifurcation lesions, chronic total occlusions, left main interventions, multi-vessel angioplasty, and small vessel interventions. He also does rota-ablation during angioplasty for tough and calcific lesion and is a proctor for this expertise. To optimize the angioplasty results, he is one of the few experts using imaging studies like IVUS and OCT and to assess hemodynamic significance FFR study. He is the only cardiologist in this part of the country trained for antegrade dissection, re-entry technique, and retrograde technique in totally occluded lesions. He maintains his interest in non-coronary interventions with balloon dilatations of valves (mitral, aortic, pulmonary), dilatation and stenting of Coarctation, device closures of septal defects, septal ablation in HOCM, peripheral vascular interventions including carotids, endovascular management of aortic aneurysm and dissections. He is trained in atherectomy with eluting ballooning for SFA and PA lesions in peripheral interventions.
