Gregory M. Hirsch Hypertrophic Cardiomyopathy Center

The Gregory M. Hirsch Hypertrophic Cardiomyopathy Center, housed within pediatric cardiology, is dedicated to providing individualized care, treatment and support to patients and families with hypertrophic cardiomyopathy (HCM). It is the first facility established in the area to screen families for HCM. This unique approach enhances care and communication between medical staff and family members.

The Gregory M. Hirsch HCM Center is proud of our inter-disciplinary team approach. Together, experts in cardiology, genetics, radiology, pathology, electrophysiology, Child Life and Social Work Services offer optimal patient care.

Although hypertrophic cardiomyopathy affects 1 in 500 individuals, making HCM a common occurrence, it is often unrecognized and misdiagnosed. An evaluation by an experienced, knowledgeable team is critical to managing this complex disease. The specialized cardiologists and nurses at the Gregory M. Hirsch Center are trained to recognize the subtleties of HCM.

Knowledge is a key component in managing and living with hypertrophic cardiomyopathy. The Gregory M. Hirsch Centeris dedicated to education, not only for the patient and family, but for the lay and professional community as well.

Congenital Heart Disease:
Of all heart problems in children, congenital heart defects (those present at birth) are the most common, afflicting nearly one out of every 100 babies and some 30-35,000 children each year in the US. Forms of congenital heart disease include:
Atrial Septal Defect (ASD) - an opening in the septum that divides the left and right upper chambers.
Coarctation of the Aorta - a narrowing of the aorta.
Tetralogy of Fallot - this complex heart malformation involves a combination of four defects.
Transposition of the Great Arteries – a defect in which the aorta and pulmonary artery are reversed.
Ventricular Septal Defect (VSD) – an opening in the septum that divides the right and left lower heart chambers.
Hypoplastic Left Heart Syndrome – occurs when the left side of the heart is underdeveloped.
Acquired Heart Disease:
Acquired heart disease can develop in children after an illness. The four main types of acquired heart disorder in children are:
Kawasaki disease – an illness that occurs mainly in young children and may leave the heart muscle or coronary arteries damaged.
Myocarditis – an inflammation of the heart due to a viral infection.
Cardiomyopathy – a disease of the heart muscle caused by either a genetic disorder or an infection. 
Rheumatic heart disease – caused by rheumatic fever and may lead to heart muscle and valve damage.
Rhythm Disturbances:
Any variation from the normal rhythm of the heartbeat:
Bradycardia – a heart rate slower than normal for age
Tachycardia – a heart rate faster than normal for age
Supraventricular tachycardia – the most common abnormal tachycardia that occurs in the upper chambers
Palpitations – a single or multiple irregular beat
Wolffe-Parkinson White syndrome – an abnormal conduction pathway running between the upper and lower chambers
Ventricular tachycardia – a fast rate that starts in the lower chambers
