Transthoracic pulmonary artery radiofrequency denervation (TPARFD) concomitantly with cardiac operations in adult atrial septal defect with pulmonary arterial hypertension: case report

Pulmonary arterial hypertension (PAH) is a life-threatening progressive disorder caused by increased resistance in the pulmonary vasculature. The condition may lead to right-sided heart failure and death. A 56-year-old woman was referred for pulmonary arterial hypertension (PAH) with atrial septal defect, mitral regurgitation, and tricuspid regurgitation. Hemodynamic parameters were obtained by right heart catheterization. She underwent transthoracic pulmonary artery radiofrequency denervation (TPARFD), to relieve the pulmonary artery pressure, while concomitantly undergoing mitral valvuloplasty with 28 # Sorin ring, patch closure of atrial septal defect, and tricuspid annuloplasty with 28 # Edwards MC3 ring. Her hemodynamic parameters and functional capacity showed marked improvement after TPARFD.
