Simultaneous Hybrid Coronary Revascularization

Simultaneous hybrid coronary revascularization (sHCR) is a new and innovative way of treating coronary artery disease by combining the advantages of two standard treatment options into one operative setting: percutaneous coronary intervention with stents and coronary artery bypass graft surgery.
With stent procedures, blocked or narrowed coronary arteries (blood vessels that supply the heart muscle with oxygen and nutrients) are opened by an interventional cardiologist using a thin, flexible tube (catheter) inserted through the leg or wrist artery and stents (tiny mesh coils) to prop open the blocked coronary artery to restore blood flow.
Stent advantages/strengths include:
•Minimally invasive
•Fewer complications
•Rapid recovery
With bypass surgery, blood flow around blocked or narrowed coronary arteries is achieved by a cardiac surgeon using blood vessels (arteries and veins) from the body to “bypass” the blocked or narrowed coronary arteries.
Bypass surgery advantages/strengths include:
•Long-term symptom relief
•Long-term results
By bringing together the strengths of stent procedures and bypass surgery, Northwestern’s Simultaneous Hybrid Coronary Revascularization Program:
•Blends stenting and bypass surgery in one operative setting
•Reduces risk while maximizing benefits
sHCR provides patients with the longest lasting and least invasive treatment possible for coronary disease and the combined expertise of interventional cardiologists and cardiac surgeons working together in the same operative setting. In addition, sHCR advantages include:
•Minimally invasive chest incision
•Shorter hospital stay
•Faster return to normal activities
•Eliminates the need for heart-lung bypass (technique of temporarily taking over the function of the heart and lungs during surgery) and its associated risks

What is sHCR?

It is well understood that arteries attached to the chest wall, thoracic arteries, are the arteries of choice for bypassing blocked or narrow coronary arteries because they remain open long term. sHCR includes using the thoracic artery to “bypass” the left anterior descending coronary artery. Remaining blocked coronary arteries are opened using stents.
sHCR can also be combined with minimally invasive heart valve repair/replacement procedures.

Hybrid Cardiac Operating Room

sHCR is performed in our state-of-the-art hybrid cardiac operating room. The hybrid operating room brings the most advanced cardiac surgery equipment and high-powered imaging (like an x-ray) equipment to the interventional cardiologists and cardiac surgeons to perform sHCR, all in one setting.

Patient Selection

A discussion with your cardiologist will help determine if you are a candidate to receive sHRS.

Team Approach

As part of the Center for Coronary Disease, the Simultaneous Hybrid Coronary Revascularization Program is led by Mark J. Ricciardi, MD, and Hyde M. Russell, MD. Dr. Ricciardi is an interventional cardiologist and medical director of the program. Dr. Russell is a cardiac surgeon and the surgical director of the program. Together these physicians and an outstanding multidisciplinary team use a systematic approach to manage patients undergoing sHCR.
