INTRODUCTION: @entity8577 is defined as a group of diseases characterized by a progressive increase in pulmonary vascular resistance that results in @entity712 and @entity204 . Although therapies exist to improve hemodynamic instability and symptoms, there is no cure for @entity120 and it remains a life-threatening condition. A recent study performed in China reported, for the first time, the effect of pulmonary arterial denervation on functional capacity and hemodynamics in @entity1 with refractory @entity8577 . CASE PRESENTATION: We report a case of a 60-year-old white Brazilian @entity1 , with controlled @entity101 and stage 2 @entity28 who complained of progressive fatigue with moderate to light exertion of approximately 1 year's duration. During this period, he underwent myocardial perfusion scintigraphy without evidence of obstructive @entity63 . He had no clinical evidence of @entity712 . He had undergone biological mitral valve replacement 3 years previously for @entity4794 and ablation of @entity2917 18 months previously. At the time of valve replacement, he had no reported evidence of @entity120 . His echocardiogram showed normal function of a mitral prosthesis, normal global left ventricular systolic function (left ventricular ejection fraction 62 % measured using the Teichholz method), stage I @entity67 , and a mean systolic pulmonary arterial blood pressure of 50 mmHg. In the 6-minute walk test, the @entity1 walked 104 meters. Catheterization of his right heart chambers and pulmonary arteries confirmed the diagnosis of @entity120 . Electroanatomic reconstruction of the right ventricular outflow tract and pulmonary artery was performed under direct fluoroscopic visualization, and a merger was made with a formatted image of cardiac computed tomography angiography. Then we performed irrigated cardiac catheter ablation of the pulmonary trunk. CONCLUSIONS: At the @entity1 's 3-month follow-up, he showed improvement in functional class for fatigue on major exertion, increased distance walked in the 6-minute walk test, and reductions in pressure of both the right cavities and the pulmonary artery. Currently, with 6 months of clinical follow-up, the @entity1 has maintained his functional classification and is pedaling his bicycle.
