Chest Pain Center

The Chest Pain Center at TMC offers rapid, round-the-clock, evidence-based treatment of heart attack and suspected heart attack.

The center is accredited by the American College of Cardiology (ACC). In addition to the standard accreditation, TMC has received an enhanced accreditation from ACC. This makes it a Chest Pain Center with Primary PCI. Hospitals awarded this designation have primary percutaneous coronary intervention (PCI) available 24 hours a day, 7 days a week.

Chest Pain Center & PCI Accreditations


We offer a wide range of services to diagnose, treat, and help you recover from cardiovascular conditions.

Cardiac Catheterization

ACC Cardiac Cath Lab Accreditation logoTMC was awarded Cardiac Cath Lab Accreditation with PCI by the American College of Cardiology.

Catheter-based interventional procedures are performed in THI's fully-digital catheterization laboratories. Cardiac catheterization uses radiological equipment to both diagnose and treat some forms of heart disease. Interventional cardiologists at THI specialize in transradial cardiac catheterization, in which they can access a patient's heart through a catheter in the wrist instead of the femoral artery in the thigh.

The heart specialists at THI perform thousands of interventional procedures every year, including about 1,600 cardiac catheterizations and more than 600 PTCAs (percutaneous transluminal coronary angioplasties) and other interventional procedures.

Cardiac CT for Calcium Scoring

Calcium scoring shows detailed images of your coronary arteries, which helps physicians identify and locate calcified plaque. Calcified plaque can build up and reduce the amount of oxygen rich blood flowing to the heart. It is often used to determine if a patient has coronary artery disease.

Cardiovascular Surgery

Cardiovascular surgeons at THI perform innovative surgical procedures, including beating heart bypass, a type of open heart surgery where cardiac surgeons operate while a patient's heart continues to pump blood through the body.

Extracorporeal Membrane Oxygenation

Extracorporeal membrane oxygenation (ECMO) is a form of partial cardiopulmonary bypass at the bedside that uses a pump and artificial lung to function as the heart and lungs during the healing process from various injuries.
