Heart Surgery | Traditional and Minimally Invasive | Medstar Health

Expertise in a range of traditional and minimally invasive procedures

Heart surgery is an option to treat many heart conditions. You may need heart surgery as a lifesaving procedure or when other treatments haven’t worked. Heart surgery includes a range of procedures, from relatively simple options to highly complex and challenging procedures.

Our cardiac surgery program has some of the best outcomes for heart surgery nationwide. We’re one of the area’s busiest centers for heart surgery because so many patients trust us with their care. Having helped create and test many procedures that are now used by heart surgeons everywhere, our doctors continue to be on the leading edge of this area of medicine.


Our surgeons also perform complex procedures such as:

After surgery, your doctor may prescribe cardiac rehabilitation as part of your recovery. In addition to helping you build your strength back up after surgery, cardiac rehab can help you lower the risk of future heart problems by helping you live a healthy lifestyle.


Our surgeons work closely with other heart care experts, including cardiac imaging specialists, interventional cardiologists and nurses, to provide personalized surgical care for each patient. We regularly treat conditions such as:

Atrial septal defect (ASD)

An atrial septal defect (ASD) is a hole in the wall that separates the top two chambers of the heart (atria), allowing blood to leak between the chambers.

Cardiac tumors and masses

Cardiac tumors and masses either can start growing in the heart (primary) or elsewhere in the body and travel to the heart (secondary).

Left ventricular hypertrophy (LVH)

Left ventricular hypertrophy is a thickening of the left ventricular heart muscles that can cause your heart to become stiff.

Patent ductus arteriosus (PDA)

Patent ductus arteriosus is a congenital heart defect that connects the two major heart arteries and allows oxygenated and unoxygenated blood to mix.

Patent foramen ovale (PFO)

Patent foramen ovale is a congenital heart condition in which the naturally occurring opening between the heart’s upper chambers does not close after birth.

Pericardial effusion

Pericardial effusion is a dangerous buildup of fluid around the heart. Without treatment, this condition can cause heart failure or death.

Pulmonary atresia

Pulmonary atresia is a congenital heart disorder that causes malformation of the valve controlling blood flow to your lungs.

Restrictive cardiomyopathy

Restrictive cardiomyopathy is a stiffening of the heart’s two lower chambers, the ventricles, which prevents them from expanding properly as they fill with blood.

Rheumatic heart disease

Rheumatic heart disease occurs when rheumatic fever, an inflammatory disease, causes permanent damage to the heart valves.

Sarcoidosis (cardiac)

Sarcoidosis causes lumps to form in your heart, lungs or lymph nodes and can damage these organs.

Tetralogy of fallot

Tetralogy of fallot is a combination of four congenital structural heart that disrupt the normal flow of blood through the heart.

Transposition of the great arteries

Transposition of the great arteries is a condition present from birth in which the positions of the heart’s two main arteries are reversed. This condition requires lifelong follow-up care after it’s repaired in infancy.

Truncus arteriosus

Truncus arteriosus is a heart condition present from birth in which the two main arteries taking blood away from the heart are replaced by a single artery.

Univentricular heart

The term univentricular heart refers to a group of heart conditions present at birth in which one of the lower chambers of the heart (ventricles) is smaller, underdeveloped or missing a valve. In rare cases, one of the ventricles may be missing altogether.

Ventricular septal defect (VSD)

Ventricular septal defect, or VSD, is a hole in the wall separating the heart’s two lower chambers.


Cardiac catheterization

Cardiac catheterization is a minimally invasive way to diagnose and treat a variety of heart and vascular conditions by guiding thin, flexible tubes called catheters through blood vessels to problem areas.

Computerized tomography (CT) scan

The cardiac computed tomography scan, or cardiac CT, uses x-rays to create three-dimensional images of your heart and blood vessels.


An echocardiogram uses high-frequency sound waves to create images of your heart.

Electrocardiogram (ECG)

An electrocardiogram, also known as an ECG, measures the heart’s electrical activity.

Magnetic resonance imaging (MRI)

Magnetic resonance imaging, better known as cardiac MRI, is a combination of radio waves, magnets and computer technology to create images of your heart and blood vessels.

Stress tests

Stress tests are used to assess how your heart works during physical activity. There are several types of stress tests, including treadmill or bike stress tests, nuclear stress tests, stress echocardiograms and chemically induced stress tests.

Cardiac rehabilitation

Recover faster and improve your quality of life after heart disease or treatment with help from our exercise physiologists, physical therapists and dietitians.
