A coronary artery fistula is a rare, abnormal, usually congenital defect where a coronary artery, incorrectly enters a heart chamber or different blood vessel.

Normally the right atrium is connected to the right ventricle which pumps oxygen-poor blood from the body tissues, out to the lungs to get oxygen. The left atrium collects the oxygenated blood from the lungs and is connected to the left ventricle which pumps the oxygen-rich blood out to the body. In double inlet left ventricle, both atria connect to one ventricle and the right ventricle is small.

Shone’s syndrome, is a rare form of congenital heart disease where there is a combination of four left-sided heart defects.

The ventricles are two of the hearts' four chambers. When a baby is born with only one of the ventricles functioning  properly or missing, this is called "single ventricle defect".

The Harmony Transcatheter Pulmonary Valve is the first FDA-approved valve that offers older children and adults in need of pulmonary valve replacement.

Collateral vessels are abnormally large blood vessels that connect the aorta to the pulmonary artery, and are usually associated with a congenital abnormality of the heart. The process of closing these collateral vessels off is called ligation of collateral vessels.

Transcatheter patent ductus arteriosus closure is a method of correcting PDA without the need for a surgical procedure and avoiding a scar on the chest/back.

Balloon angioplasty is a non-surgical procedure used to restore the flow of blood through blocked or narrow vessels. It is performed using a catheter, is less invasive than surgery, and in some instances more effective, such as in vessels that cannot be easily reached by the surgeon.
