Cardiac vignette: isolated pulmonary regurgitation.

Isolated pulmonary regurgitation (PR) is a rare occurrence with only a handful of documented cases worldwide. Though usually well tolerated in childhood, chronic PR can eventually lead to RV dysfunction and ventricular arrhythmias. In this cardiac vignette, we describe a case of isolated PR in a young female presenting with syncope and explore the natural history, different investigative modalities as well as issues in clinical management of this rare condition.
