Various forms of heart disease include: Alcoholic cardiomyopathy Aortic regurgitation Aortic stenosis Arrhythmias Cardiogenic shock Congenital heart disease Coronary artery disease (CAD)Dilated cardiomyopathy Endocarditis Heart attack (myocardial infarction) Heart failure Heart tumor Hypertrophic cardiomyopathy Idiopathic cardiomyopathy Ischemic cardiomyopathy Acute mitral regurgitation Chronic mitral regurgitation Mitral stenosis Mitral valve prolapse Peripartum cardiomyopathy Pulmonary stenosis Stable angina Unstable angina Tricuspid regurgitation Alternative Names Cardiovascular disorders Causes, incidence, and risk factors The most common cause of heart disease is a narrowing of or blockage in the coronary arteries supplying blood to the heart muscle itself (coronary artery disease). Some heart diseases are present at birth (congenital heart disease). Other causes include: Hypertension Abnormal heart valve function Abnormal heart rhythm Weakening of the heart's pumping ability caused by infection or toxins Continue reading this article

Open heart surgery (Doctor-Reviewed information)
Open heart surgery is any surgery where the chest is opened¿and surgery is performed on the heart. The term "open" refers to the chest, not the heart itself. The heart may or may not be opened, depending on the type of surgery. Open heart surgery includes surgery on the heart muscle, valves, arteries, or other structures. A heart-lung machine (also called cardiopulmonary bypass) is usually during conventional open heart surgery¿to help provide oxygen-rich blood to the brain and other vital organs. The machine also pumps, supplies oxygen,¿removes carbon dioxide from the blood, and provides anesthesia to keep the patient asleep during surgery. The definition of open heart surgery becomes confusing in light of new procedures being performed on the heart through smaller incisions. There are some new surgical procedures being performed that are done with the heart still beating. Minimally invasive heart surgery (MIDCAB, OPCAB,¿RACAB), including¿robotic-assisted heart surgery,¿is still considered¿open heart surgery. However, these procedures are being used in some patients as an alternative to open heart surgery¿requiring the heart-lung machine.
