The Interventional Cardiology Fellowships offer a one-year, ACGME-accredited interventional cardiology program as well as non-accredited, advanced fellowships in structural heart disease, endovascular intervention, and complex and high-risk coronary intervention (CHIP).

First-year Interventional Cardiology Program

Diagnostic Techniques

The one-year Interventional Cardiology Fellowship Program offers a core procedural experience in the following diagnostic techniques: coronary arteriograms, ventriculography, hemodynamics, intravascular ultrasound, intracoronary Doppler flow, and pressure monitoring. The program also offers core experience in the following interventional techniques: balloon angioplasty, stent implantation, saphenous vein graft and arterial graft interventions, distal embolic protection during angioplasty, urgent angioplasty for acute coronary syndromes, primary angioplasty for acute myocardial infarction, directional and rotational atherectomy techniques, intra-aortic balloon counterpulsation and other techniques of mechanical circulatory support, intravascular ultrasound, and coronary flow-pressure measurement (coronary flow reserve, fractional flow reserve). Additional techniques employed based on the frequency of the cases include laser atherectomy techniques, thrombectomy techniques, cardiac valvuloplasty, endomyocardial biopsy, intravascular radiation therapy, and local drug delivery (only as part of investigational protocols).

Management of Procedural Complications

Interventional cardiology fellows gain extensive experience with the management of procedural complications and the appropriate use of mechanical and pharmacological agents. Such complications include coronary dissection, intracoronary thrombosis, spasm, perforation, slow-flow, no-reflow, cardiogenic shock, left main dissection, cardiac tamponade, peripheral arterial (access site) thrombosis, dissection or embolization, case selection for surgical repair, pseudoaneurysm, arteriovenous fistulae, and nerve injury. In addition, all interventional cardiology fellows receive experience in the full range of arterial vascular access techniques. These include both transfemoral approaches and approaches from the arm (brachial/radial). Each fellow will acquire experience treating the full range of coronary lesion morphologic subsets. This includes type A, B, and C lesions, total occlusions, heavily calcified lesions, saphenous vein graft lesions, and lesions accessed via arterial bypass grafts.


The Interventional Cardiology Fellowship Program is organized into three rotations (level I, level II, and level III) that denote the stepping of the fellows from simple cases to more complex cases progressively. Each interventional cardiology fellow participates in a minimum of 300 and maximum of 500 coronary interventional cases during the one-year program.

Clinical Experience

In addition to procedure skills, each interventional cardiology fellow will acquire clinical experience in the following areas during the care of patients who are evaluated for interventional therapy:

  • Case selection for interventional or surgical cardiac therapy for heart disease in the outpatient setting and longitudinal follow-up after such procedures are performed (outpatient setting, mainly chronic heart disease, comparative experience with medically treated patients will be included).
  • Pre- and post-procedure patient care (in-hospital, acute ischemic syndromes).
  • Subspecialty consultation in interventional cardiology in the setting of hospitalized patients, emergency unit patients, coronary care unit patients, and surgical intensive care or surgical wards.

Weekly cardiac catheterization and interventional cardiology conferences, hemodynamics and interventional cardiology didactic lecture series, as well as monthly quality assurance conferences; interventional cardiology-cardiothoracic surgery conferences, endovascular grand rounds, and the clinicopathological conference of the Department of Medicine will supplement the clinical experience of each fellow.

Clinical Research and Education

All interventional cardiology fellows will have the opportunity to participate in clinical research projects and a large variety of structured educational activities in relation to the annual international conference on Transcatheter Cardiovascular Therapeutics, which is organized by the teaching faculty. All interventional cardiology fellows are expected to present abstracts and publish scientific papers stemming from their academic work during fellowship.

Advanced Interventional Fellowships (2nd Year)

During the non-ACGME, advanced training year, fellows will acquire expertise in one of three areas: Applicants must have completed general cardiology and interventional cardiology fellowships. Advanced fellows will be appointed as Instructors in the Columbia University Department of Medicine.

  • Structural Heart Disease Fellowship provides experience in the interventional and medical therapy of structural heart disease, with a special focus on transcatheter valve therapeutics. This fellowship is coordinated through the Structural Heart and Valve Center.
  • Endovascular Intervention Fellowship provides training in endovascular diagnostic and interventional procedures.
  • Complex and High-risk Coronary Intervention (CHIP) Fellowship provides training on complex coronary interventions, with a particular focus on chronic total occlusions (CTO) PCI and hemodynamic support.
