Jointly led by cardiologists from NSMC and Massachusetts General Hospital, our Catheterization and Interventional program provides a full range of effective therapies, including angioplasty, stenting, atherectomy and clot extraction.  

Our two catheterization laboratories use state-of-the-art digital imaging devices that enable our physicians to get intricate views of the heart and arteries.

Door to balloon time

Percutaneous coronary intervention (PCI) is a way to open blocked heart arteries. A balloon catheter is inserted into the affected artery and is then inflated to open the blockage. NSMC is consistently able to perform this life-saving measure on cardiac patients within 90 minutes, well above the national average.

Peripheral Intervention Program

Our Peripheral Interventional Program provides diagnosis, carotid artery angioplasty and stenting, and offers advanced treatment of peripheral vascular disease. Cardiologists work closely with other NSMC specialists to offer the most advanced therapies.
