Single Ventricle With Hypoplastic Left Heart Syndrome in a 22-Year-Old Male: A Rare Case Report

Uni-ventricle transposition of great arteries with ductus-dependent pulmonary circulations with hypoplastic pulmonary atresia (PA) represents rare cardiac malformations. We are presenting a unique case of a 22-year-old male who complained of dizziness since morning with numbness of the left lower and upper limbs. He also complained of palpitations on and off for two to three years with episodes of cyanosis on exertion. He gave a history of cough with frothy pink sputum at the same time. At birth, he was diagnosed to have cyanotic congenital heart disease (CCHD), for which he was prescribed a combination of ambrisentan 5 mg and tadalafil 20 mg and tablet aspirin 75mg along with some lifesaving modalities like proper hydration and phlebotomy as and when required. He was told to go for high-risk surgery like Blalock Taussig shunt or bidirectional Glenn. A Blalock Taussig shunt is a short tube only a few mm wide, which makes a path for blood to go from the arterial circulation to the lungs and bidirectional Glenn sends blood directly from the upper body to the lungs. Strict compliance with drug therapy is implied for the patient for a better outcome.
