Abstract

Pulmonary arterial hypertension (PAH) is a perilous disease that precipitates right ventricular hypertrophy, induces right heart failure, and exerts deleterious ramifications on prognostic outcomes. The establishment of atrial communication can create a right-to-left shunt, thereby ameliorating hemodynamic parameters. Previous reports suggested that opening of a patent foramen ovale (PFO) was common in patients with severe PAH, but exhibited no discernible impact on long-term survival. We reported the case of a 39-year-old man with severe idiopathic PAH, who underwent reopening of the PFO due to severe cough and hemoptysis, followed by a marked amelioration in symptoms and a substantial decrease in pulmonary arterial pressure. The patient has survived for more than 12 years, persisting in World Health Organization functional class Ⅱ with mild PAH.

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
