The Cardiac Catheterization Laboratory at the Mount Sinai Hospital is among the highest volume centers, yet also among the safest interventional catheterization laboratories in the US. The Cath Lab performs over 5,000 interventions every year. We see a large volume of referred cases with high risk features, thus providing our trainees with ample exposure to complex PCI cases and confidence by hands-on learning as primary operators. Our hospital is Ranked #1 in New York and #4 in the nation.
