Univentricular heart (UVH) is a severe congenital cardiac malformation characterized by both atria related entirely or almost entirely to one functionally single ventricular chamber. The clinical manifestations include congestive heart failure, failure to thrive, cyanosis, hypoxemia and neurodevelopmental disabilities.
Features include very common findings: Pulmonary venous hypertension and Valvular pulmonary stenosis; and common findings: Failure to thrive, Congestive heart failure, Respiratory distress, and Tachypnea and others. 14 total HPO annotations.
Organ System | Phenotype Count | Example Features |
