Persistent pulmonary artery hypertension (PAH) after balloon mitral valvuloplasty (BMV) is not uncommon, and is generally associated with established pulmonary vascular disease, an inadequate result, or the development of mitral regurgitation. An unfavorable mitral valve morphology with a smaller post-procedural mitral valve area is among the most common causes of the condition. While routine cardiac catheterization is no longer recommended prior to intervention in valvular heart

disease, patients with persistent PAH after BMV should undergo a thorough evaluation before they are considered for repeat BMV. Here, a rare case is reported of symptomatic persistent PAH in a patient referred for a third BMV, less than one year after the previous intervention, where a hypertensive patent ductus arteriosus was identified, the closure of which led to a regression of the PAH.
