Unmet needs in diagnosis and management of portopulmonary hypertension: How far have we reached?

Abstract

Portopulmonary hypertension (POPH), a form of pulmonary artery hypertension, occurs because of portal hypertension. Pulmonary hemodynamics and right heart function are key entities that are considered when diagnosing and treating POPH. Medical management, combined with liver transplantation, offers a unique opportunity of POPH “cure,” however transplant risk can be significant as it relates to the severity of POPH. In addition to recent POPH practice guidelines, continued efforts can be suggested to improve our understanding of prognostic factors, investigate newer medical treatments, and improve outcomes of POPH. Herein, we identify specific “unmet needs” that focus on expanding and complementing current POPH practice guidelines.
