Apicoaortic Conduit (AAC), also known as Aortic Valve Bypass (AVB), is a cardiothoracic surgical procedure that alleviates symptoms caused by blood flow obstruction from the left ventricle of the heart.
Once the wire is across, a large tube is used to place the transcatheter heart valve through the femoral vein and inferior vena cava into the aorta and from there the heart. This otherwise resembles the transfemoral approach. Afterwards, the hole in the aorta is closed with a self-collapsing nitinol device designed to close holes in the heart ...

An aortic homograft is an aortic valve from a human donor, retrieved either after their death or from their heart if they are undergoing a heart transplant. [17] A pulmonary autograft, also known as the Ross procedure is where the aortic valve is removed and replaced with the patient's own pulmonary valve (the valve between the right ventricle ...
Significant complications of the operation include bleeding, heart problems (heart attack, arrhythmias), stroke, infections (often pneumonia) and injury to the kidneys. Three coronary artery bypass grafts, a pedicled LITA to LAD and two saphenous vein grafts – one to the right coronary artery system and one to the obtuse marginal system.
Ventricular aneurysms are usually complications resulting from a heart attack. When the heart muscle (cardiac muscle) partially dies during a heart attack, a layer of muscle may survive, and, being severely weakened, start to become an aneurysm. Blood may flow into the surrounding dead muscle and inflate the weakened flap of muscle into a bubble.
This procedure makes heart surgery possible for patients who were previously considered too high risk for traditional surgery due to age or medical history. [ 5 ] [ 6 ] Patients referred for this procedure may have coronary artery disease (CAD); aortic, mitral or tricuspid valve diseases; or previous unsuccessful stenting.
This was funded by a three-year $6.2 million contract to Thermedics and Children's Hospital, Boston, MA, from the National Heart, Lung, and Blood Institute, a program of the NIH. [24] The early VADs emulated the heart by using a "pulsatile" action where blood is alternately sucked into the pump from the left ventricle then forced out into the ...
