The surgery allows blood to be delivered to the lungs via central venous pressure rather than via the right ventricle. [3] Patients typically present as neonates with cyanosis or congestive heart failure. [4] Fontan completion is usually carried out when the patient is 2–5 years of age, but is also performed before 2 years of age. [5] [6]
It remains unknown if surgery is superior to optimal medical therapy. The STICH trial (Surgical Treatment for IschemiC Heart Failure) will examine the role of medical treatment, coronary artery bypass surgery and left ventricle remodeling surgery in heart failure patients. Results are expected to be published in 2009 [needs update] and 2011. [56]
Cardiac surgery, or cardiovascular surgery, is surgery on the heart or great vessels performed by cardiac surgeons.It is often used to treat complications of ischemic heart disease (for example, with coronary artery bypass grafting); to correct congenital heart disease; or to treat valvular heart disease from various causes, including endocarditis, rheumatic heart disease, [1] and ...
Heart Failure: The single ventricle must support both systemic and pulmonary circulation, which can lead to heart failure if demands exceed functional capacity. [ 30 ] Arrhythmias: Abnormal heart rhythms can occur due to the congenital defect or secondary to manipulation of cardiac tissue during surgery.
The first uses a cardiopulmonary bypass machine, a machine which takes over the functions of the heart and lungs during surgery by circulating blood and oxygen. With the heart in cardioplegic arrest, harvested arteries and veins are used to connect across problematic regions—a construction known as surgical anastomosis.
Aortic valve replacement is a cardiac surgery procedure whereby a failing aortic valve is replaced with an artificial heart valve.The aortic valve may need to be replaced because of aortic regurgitation (back flow), or if the valve is narrowed by stenosis.
