Interventional Cardiology

Interventional cardiology uses non-surgical methods to treat heart conditions. They are often catheter-based (small tubes inserted into the arteries and guided to the heart) procedures that open blocked arteries to improve blood flow to the heart. TMC offers a wide range of non-surgical, interventional cardiac care services including heart catheterization and electrophysiology performed by cardiologists working as a team with registered nurses and technologists.

Interventional cardiology services include:

  • Diagnostic and interventional cardiac catheterizations: the insertion of a small tube into the heart through the arteries in the arm or groin
  • Angioplasty: the insertion of a device to open blocked arteries
  • Intracoronary stent placement: the placement of a small mesh tube in the artery to increase blood flow
  • Innercoronary ultrasound: a diagnostic imaging procedure that takes place within the arteries and heart

Our Cardiac Catheterization Electrophysiology Suite, commonly called the Cath Lab, is a highly complex, technical area where most cardiac diagnostics and interventional invasive cardiac procedures are performed.

The Cath Lab Suite at TMC consists of six catheterization rooms, a state-of-the-art Stereotaxis electrophysiology suite and a hybrid cath-lab suite. The Cath Lab is equipped to perform assessment of total heart function including the evaluation of coronary artery disease, electrophysiology/ablation procedures, as well as many other therapeutic procedures.

If you have a visit to the Cath Lab scheduled, please read the general procedure instructions below and watch the video to help ensure that your visit will be short and comfortable and you know what to expect.

Structural Heart Program

Tucson Medical Center offers a Structural Heart Program that makes us a one-stop institution for patients with advanced or complex structural heart disease. We provide innovative care with a team of physicians from a range of specialties that work together with the patient to evaluate and come up with the best treatment plan to ensure the best possible outcome.

This program focuses on minimally invasive treatments for patients who cannot go through traditional open-heart surgery. In addition to an advanced team of specialists, TMC provides access to some of the most advanced technology available.

Transcatheter Valve Therapies:

Transcatheter Aortic Valve Replacement: TAVR is for patients who have been diagnosed with aortic stenosis, a life-threatening disease that narrows the aortic-valve opening and makes it hard for blood to flow normally to the entire body. This procedure does not require open chest surgery.

Transcatheter Aortic Valve-in-Valve Replacement: For patients who have previously undergone open-heart surgery and received a bioprosthetic aortic valve. If the valve begins to fail, physicians use this procedure to deploy a new working valve inside the old valve without the need to perform an additional open-heart surgery.

Transcatheter Mitral Valve-in-Valve Replacement: This procedure is a great alternative for patients who are high risk for undergoing open-heart surgery to replace a failing, surgically-placed mitral valve. The procedure is similar to TAVR in that it is completed without opening the chest and places a new valve inside the failing bioprosthetic valve.

MitraClip Transcatheter Mitral Valve Repair: MitraClip provides an alternative to patients with mitral-valve regurgitation who are unable to undergo traditional open-heart surgery. For patients, this procedure can be life-changing, improving their overall health, energy and emotional well-being.

Perivalvular Leak Repair: This procedure is for patients who have undergone a valve replacement surgery in the past and have developed a leak around the valve. Using this procedure, physicians are to place a patch around the site of the leak without open-heart surgery.

Structural Heart Therapies:

WATCHMAN: This procedure helps reduce the risk of stroke in patients who have atrial fibrillation and not suitable for long-term blood thinning therapy.

PFO/ASD Closure: Patent foramen ovale and atrial septal defects are conditions involving a hole in the heart. The TMC Structural Heart Program includes permanent surgical closure.
