1. Unit Description

Cardiac Catheterization began at University Hospital (UH) now known as University Malaya Medical Centre (UMMC) in 1971 by Prof H.O.Wong, Dr. Singham and Dr.T.H.Goh investigating congenital and rheumatic heart disease patients.

This unit provides teaching, research and treatment of cardiovascular disease. The Invasive Cardiovascular Laboratory provides 24 hour services 7 days per week and collaborates with several hospitals in the Klang valley.
