Types of surgeries


Coronary Artery Bypass Graft

CABG surgery creates (or “bypasses”) new routes around blocked arteries to allow proper blood flow the heart needs for oxygen and nutrients by sewing grafted vessels (taken from the leg, forearm or chest wall) to the coronary arteries beyond the narrowing or blockage.procedures.


Heart Valves

For blood to go in only one direction, forward, it must pass through the heart valves, which function as one-way doors, opening and shutting with each beat of the heart. Just as there are four chambers to the heart, there are four heart valves. Blood must pass through one of these valves each time it leaves a chamber.



Lung Surgery

If the tumor is small and located on the outer perimeter of the lung, video assisted thoracic surgery (VATS), a minimally invasive approach may be employed. VATS, or thoracoscopy, can be used to remove cancer, perform lung biopsy, and treat diseases causing the lung to collapse or fluid buildup in the chest cavity. 


Atrial Fibrillation

  This procedure has been revised to the Cox-Maze IV which allows the use of high-frequency radio waves or freezing techniques to break up the abnormal electrical pathways that cause the fibrillation. By destroying these abnormal pathways, in a complex pattern, a “maze” is created that allows only one electrical signal to travel across the heart, restoring a regular rhythm. 


Aneurysm Repair

When the aorta, a major artery, develops a weak spot, enlarges, or balloons outward, it is referred to as an aortic aneurysm.  An aneurysm occurring in the middle or lower abdomen are referred to as abdominal aortic aneurysm.  If the aneurysm occurs in the chest this is referred to as a thoracic aortic aneurysm.  Most aneurysms display few or no warning signs.  



Transcatheter Aortic Valve Replacement is a way to implant an artificial aortic valve inside the patient’s own aortic valve without undergoing an open incision and placement on a cardiopulmonary bypass machine.  Currently it is only performed on patients that are intermediate or high risk for standard aortic valve replacement, and it is only for aortic valves with aortic stenosis.
