Quadricuspid pulmonary valve with pulmonary hypertension: a case report

Background: The quadricuspid pulmonary valve (QPV) is a relatively rare heart congenital anomaly. It is usually asymptomatic and incidentally detected. Case summary: A 52-year-old woman presented with paroxysmal palpitations and chest tightness after exertion. After a series of examinations, we finally diagnosed her with QPV and pulmonary hypertension. The symptoms have improved significantly with medications, and subsequently, the patient was discharged. Discussion: This case demonstrated the crucial role of multimodality imaging in evaluating the non-invasive depiction of pulmonary valve disease.
