Dr. Raja Hatem performed a chronic total occlusion angioplasty at Sacré-Cœur Hospital in Montreal on September 29, 2026, and transmitted the operation live to approximately 150 cardiologists across Canada.

The broadcast was organized to educate fellow physicians about the ultra‑specialized, non‑open‑chest technique that repairs completely blocked arteries, a procedure that only a few Canadian cardiologists are qualified to carry out.
