Adult Congenital Heart Disease at Weill Cornell Medical College

Congenital heart disease including malformations of the heart or major blood vessels is the most common form of birth defect.  Thanks to modern day advances in the medical and surgical care, most children born with serious congenital heart defects now survive long into adulthood.

In the US, there are now more adults with congenital heart disease than children. While this represents a phenomenal medical success story, many adults with congenital heart disease require lifelong care and follow-up with the goal of living a long and healthy life. 

Program Mission

The Cornell Center for Adult Congenital Heart Disease at Weill Cornell Medical College, New York Presbyterian Hospital offers personalized, lifelong care for adult patients with congenital heart disease.  We provide a full range of inpatient and outpatient clinical services and diagnostics including cardiac catheterization and surgical repair. We offer particular expertise in minimally invasive treatment strategies for congenital heart disease. Our mission is to maximize both the cardiac health and social well-being for our congenital heart disease patients 

Services Offered

  • Consultative - outpatient and inpatient
  • Multimodality diagnostic testing
  • Comprehensive cardiac and medical management
  • Therapeutic interventional cardiac catheterization and electrophysiology therapeutics
  • Partnership with surgical specialties with expertise in congenital heart disease and perioperative management
  • High risk obstetrics & gynecology consultative services
  • Transition clinic for young adults with congenital heart disease (in joint collaboration with Cornell Pediatrics Cardiology)


Our Adult Congenital Heart Disease team includes specialists from multiple disciplines including clinical consultants in adult & pediatric cardiology, heart failure, pulmonary hypertension, high-risk obstetrics, neurology, and pulmonary medicine. We utilize the latest technologies and multimodality imaging to aid in the diagnosis of our patients including 3D-echocardiography, intracardiac echo, cardiac MRI, and cardiac CT.

Specialists in congenital electrophysiology with state-of-the-art arrhythmia mapping systems offer potential curative therapies for life-threatening arrhythmias. The cardiac interventional program offers non-surgical and minimally invasive solutions for repair of congenital cardiac defects. Our cardiothoracic surgeons specializing in adult congenital heart disease and congenital cardiac anatomy are world renown.
