Raney Zusman SurgeonsThe heart surgeons at Raney Zusman Medical Group are highly trained specialists with decades of experience in open heart surgery, and include:

The surgeons have been the dedicated cardiac team for the highly acclaimed Hoag Heart and Vascular Institute in Newport Beach since 1987, and perform over 400 open heart surgeries per year.  This places the group as one of the higher volume heart surgery practices in Orange County, CA.

The heart surgeons maintain excellence in all types of cardiac surgery, including coronary artery bypass grafting and mitral valve surgery, while pursuing cutting-edge techniques such as mitral valve repair, surgery for atrial fibrillation, robotic heart surgery, minimally invasive heart surgery and laser cardiac revascularization.  This diversity of technical skill gives the surgeons the ability to tailor the appropriate surgical procedure for an individual patient's needs. 


What is a Heart Surgeon?

A heart surgeon is also known as a "cardiothoracic" surgeon, and receives highly specialized training in surgery of the heart, lungs, and thoracic (chest) cavity.  Heart surgery involves surgical treatment for a broad spectrum of diseases, including the blood supply to the heart (the coronary arteries), heart valves, heart transplantation, and diseases of the aorta (the main artery that branches off the heart).  Our surgeons also specialize in surgery for atrial fibrillationLung surgery includes treatment for lung and chest wall cancer, as well as lung transplantation.  A cardiothoracic surgeon also manages "congenital" heart disease, which are diseases of the heart that have been present since birth.  Some of these problems may not show up until later in life and require surgical management.

Heart Surgery Training

Heart surgeons undergo extensive training to master their specialty.  In addition to 4 years of college and 4 years of medical school, heart surgeons will complete a 5 year residency in general surgery and a 3 year fellowship in cardiac surgery.  The heart surgeons at Raney Zusman Medical Group are all board-certified in cardiothoracic surgery.
