Definition Hypoplastic left heart syndrome occurs when parts of the left side of the heart (mitral valve, left ventricle, aortic valve, and aorta) do not develop completely. The condition is congenital (present at birth). Alternative Names HLHS Causes, incidence, and risk factors Hypoplastic left heart is a rare type of congenital heart disease. It is more common in males than in females. As with most congenital heart defects, there is no known cause. Approximately 10% of patients with hypoplastic left heart syndrome also have other birth defects. The problem develops before birth when there is not enough growth of the left ventricle and other structures, including the: Aorta -- the blood vessel that carries oxygen-rich blood from the left ventricle to the entire body Entrance and exit of the ventricle Mitral and aortic valves This causes the left ventricle and aorta to be incompletely developed, or hypoplastic. In most cases, the left ventricle and aorta are much smaller than normal. In patients...

Definition Left heart ventricular angiography is a procedure to look at the left side of the heart and, sometimes, the coronary arteries. Alternative Names Angiography - left heart; Left ventriculography How the test is performed Before the test, you will be given medicine to help you relax. You will be awake and able to follow instructions during the test. An intravenous line is placed in your arm. The health care provider cleans and numbs an area on your arm or groin. A cardiologist makes a small cut in the area, and inserts a thin flexible tube (catheter) into an artery. Using x-rays as a guide, the doctor carefully moves the thin tube (catheter) into your heart. When the tube is in place, dye is injected through it. The dye flows through the blood vessels, making them easier to see. X-rays are taken as the dye moves through the blood vessels. These x-ray pictures create a "movie" of the left ventricle as it contracts rhythmically. The procedure may last from 1 to several hours. How to prep...
