Quick Summary:

• Cystic Tumor of Atrioventricular Node (CTAVN) is a benign congenital tumor that is located in the heart atrium, near the atrioventricular node. The tumor has cystic configuration as the name suggests (i.e., it is present as a cyst)
• The atrioventricular node (AV node) is an important component of the heart electrical conduction system. It allows electrical signals initiated by the sinoatrial node, to be distributed to the heart ventricles (lower chambers). Any disruption in the heart’s electrical system can be serious and life-threatening
• The tumor may be diagnosed in childhood or when the individual is well into adulthood. Cystic Tumors of Atrioventricular Node are known to result in sudden death due to complete heart block (that occurs in a majority of individuals) and/or severe arrhythmias
• Often small, multicystic tumors are present that are less than a few cm in size. The tumors may cause signs and symptoms that include palpitations, chest pain, shortness of breath, and fainting
• A complete surgical excision and removal of Cystic Tumor of Atrioventricular Node (if possible) can result in a good prognosis. In a minority of individuals, severe symptoms causing sudden cardiac deaths are known to occur
