Cardiac Surgery

Danbury Hospital offers advanced cardiac surgery at Praxair Heart and Vascular Center, which provides the full continuum of care, from prevention through surgical treatment and management of complex cardiac conditions.

Supported by outstanding surgical, anesthesiology and perfusion teams, our cardiac surgeons perform the following procedures, using advanced technology in our sophisticated operating suites:

Aortic aneurysm and dissection repair

A bulge or weakening in the wall of a blood vessel. Although aneurysms can form in any blood vessel, they occur mostly commonly in the aorta, abdominal area or the chest cavity. If the aneurysm is large or causing difficulties, the weakened part of the vessel can be surgically removed and replaced with a graft of artificial material. In some cases a new procedure involving a stent/graft can be utilized to avoid open chest or abdominal surgery.

Coronary artery bypass grafts (CBAG)

A type of cardiac bypass surgery in which one or more blocked coronary arteries are “bypassed” using a blood vessel graft (usually from your own arteries and veins) to restore normal blood flow to the heart.

Typically the veins are harvested endoscopically, using minimally invasive techniques. This procedure creates new pathways for oxygen-rich blood to flow to the heart.

Minimally invasive surgery (MID-CAB, valve surgery)

A bypass around a blockage in a heart artery that can be done while the heart continues to beat (so no heart-lung machine is required) and also uses a smaller incision. Surgeons use different methods to slow down and steady the heart.

Minimally invasive valve surgery also involves a smaller incision, and a modified version of the heart-lung machine is used. Your surgeon will determine what is appropriate for you.

Valve replacement and repair

Various types of valve disease can result in either valvular stenosis, where there is a reduction in the amount of blood that can flow through the valve, or valvular insufficiency, where the valves do not close completely and blood leaks backward across the valve. Your surgeon may make the decision to repair or replace a valve that is not working correctly.

In the case of a valve repair, typically involving the mitral or tricuspid valve, weakened portions of the valve are removed. The valve is then strengthened and shortened to alleviate the leakage. Mitral valve repair is almost always preferred to mitral valve replacement.

In the case of aortic or mitral valve replacement, options include a mechanical valve (manufactured from metals and plastics), or a  bioprosthetic valve, made from human or animal tissue. Your surgeon will determine which valve is best suited for your condition.

Ventricular assist device (VAD)

A mechanical pump that helps a weakened heart pump blood throughout the body. It does not replace the heart, but assists the patient's own heart to pump blood, decreasing the work of the ventricle. It can be used as a "bridge-to-transplant" for people awaiting a heart transplant or it can be used as a bridge to recovery, while a patient’s heart grows stronger.
