The IC Chat

Welcome to IC Chat with host Dr. Ashish Pershad. In this episode we examine the controversial role of transcatheter edge-to-edge mitral valve repair for functional mitral regurgitation, focusing on the COAPT, MITRAL‑FR and the newer RESHAPE Heart Failure II trials. We summarize trial differences in patient selection, anatomy (EROA and LV volumes), outcomes (heart failure hospitalizations, quality...

In this episode host Ashish Pershad reviews the ORBITA CTO randomized, double-blind, sham-controlled trial that compared CTO-PCI to a placebo procedure, explaining the rigorous design, patient selection, masking methods, and statistical approach. Pershad summarizes the results showing significant symptom improvement with CTO-PCI, discusses clinical implications—blinding, careful case selection, an...

Host Dr. Ashish Pershad introduces IC Chat’s mission to help clinicians interpret evidence-based medicine and translate trial data into everyday patient care. In this episode he appraises the CHIP-BCIS-3 randomized trial (ACC 2026 / NEJM) comparing prophylactic microaxial flow pump (Impella) versus standard care in very high‑risk elective PCI patients. The trial enrolled patients with low LVEF and...

In this episode of ICChat, Dr. Ashish Pershad MD MS  reviews and critiques the CHAMPION‑AF trial comparing Watchman Flex left atrial appendage occlusion to DOACs for atrial fibrillation. He explains the trial design, endpoints, and statistical choices, and contrasts the published results with real‑world implications. The episode highlights concerns about non‑inferiority margins, excluded procedura...
