Coexistence of multiple congenital anomalies: quadricuspid pulmonary valve, infundibular pulmonary stenosis, coronary artery anomaly, biventricular hypertrophy, and short stature

A 67-year-old man was admitted to our hospital because of exertional dyspnea. The patient was short in stature, and a quadricuspid pulmonary valve (QCPV) and outflow stenosis at the infundibulum of the right ventricle, biventricular hypertrophy, and absence of the circumflex coronary artery were revealed by computed tomography (CT) and cardiac angiography. To our knowledge, the coexistence of these five conditions has not been previously reported. The patient has been placed on regular follow-up under beta-blocker therapy for ventricular hypertrophy and has not shown worsening symptoms for 2 years.
