CardioNerds (Dr. Claire Cambron and Dr. Rawan Amir) join Dr. Ayan Purkayastha, Dr. David Song, and Dr. Justin Wang from NewYork-Presbyterian Queens for an afternoon of hot pot in downtown Flushing. They discuss a case of congenital heart disease presenting in adulthood. Expert commentary is provided by Dr. Su Yuan, and audio editing for this episode was performed by CardioNerds Intern, Julia Marques Fernandes.
A 53-year-old woman with a past medical history of hypertension visiting from Guyana presented with 2 days of chest pain. EKG showed dominant R wave in V1 with precordial T wave inversions. Troponin levels were normal, however she was started on therapeutic heparin with plan for left heart catheterization. Her chest X-ray revealed dextrocardia and echocardiogram was suspicious for the systemic ventricle being the morphologic right ventricle with reduced systolic function and the pulmonic ventricle being the morphologic left ventricle. Patient underwent coronary CT angiography which confirmed diagnosis of congenitally corrected transposition of the great arteries (CCTGA) as well as minimal non-obstructive coronary artery disease. Her chest pain spontaneously improved and catheterization was deferred. Patient opted to follow with a congenital specialist back in her home country upon discharge.

Pearls- A Case of Congenital Heart Disease Presenting in Adulthood
* Congenitally Corrected Transposition of the Great Arteries (CCTGA) is a rare and unique structural heart disease which presents as an isolated combination of atrioventricular and ventriculoarterial discordance resulting in physiologically corrected blood flow.
* CCTGA occurs due to L looping of the embryologic heart tube. As a result, the morphologic right ventricle outflows into the systemic circulation, and the morphologic left ventricle outflows into the pulmonary circulation.
* CCTGA is frequently associated with ventricular septal defects, pulmonic stenosis, tricuspid valve abnormalities and dextrocardia.
* CCTGA is often asymptomatic in childhood and can present later in adulthood with symptoms of morphologic right ventricular failure,
