Complex High-Risk Interventional Procedures (CHIP) & Chronic Total Occlusion (CTO) Program

The Yale Complex High-Risk Interventional Procedures (CHIP) & Chronic Total Occlusion (CTO) Program specializes in treating patients with complex coronary artery disease.

Patients with complex coronary disease, chronic total occlusions, and other significant co-morbidities often have limited treatment options. Many are not candidates for revascularization with traditional percutaneous techniques or open-heart surgery. Our program is able to offer nonsurgical interventional solutions for these patients.

Our Team

Our multidisciplinary care team includes world-class interventional cardiologists, cardiothoracic surgeons, heart imaging specialists, and anesthesiologists. We have specialists who have undertaken specific, dedicated training—our team performs more complex coronary interventions annually than any other hospital in Connecticut and is nationally recognized as a leading center for complex coronary interventions.

Our Approach

The Yale Complex High-Risk Interventional Procedures (CHIP) & Chronic Total Occlusion (CTO) Program provides comprehensive management of complex coronary disease using the latest treatment modalities. We use a variety of innovative technologies and techniques to optimize success, safety, and clinical outcomes. Procedures are performed with advanced imaging systems, including intravascular ultrasound (IVUS) and optical coherence tomography (OCT).
