optimized management after balloon pulmonary angioplasty in chronic thromboembolic pulmonary hypertension

Conditions: Chronic Thromboembolic Pulmonary Hypertension

Summary: balloon pulmonary angioplasty (bpa) is a new method of treatment for inoperable chronic thromboembolic pulmonary hypertension (cteph) or persistent cteph after surgery. bpa improves or even normalises hemodynamic parameters measured during a right heart catheterization. nevertheless, the vast majority of patients retain dyspnea and impaired exercise capacity despite considerable hemodynamic improvements. pulmonary rehabilitation (rhb) can improve symptoms, quality of life and exercise capacity in patients with cteph. unfortunately, access to rhb remains a concern in many countries. tele-rehabilitation (trhb) has been shown feasible and effective some cardiac or pulmonary diseases. this randomized controlled study aims at comparing the effects of trhb with the effects of simple advices regarding exercising in cteph patients with normalized or near-normalized pulmonary hemodynamics after bpa treatment.

chronic thromboembolic pulmonary hypertension (cteph) is a complication of pulmonary embolism leading to dyspnea, effort limitation and sometimes right heart failure and death. balloon pulmonary angioplasty (bpa) is a new method of treatment for inoperable cteph or persistent cteph after surgery. bpa restores blood flow in the treated areas and improves or even normalises hemodynamic parameters measured during a right heart catheterization. nevertheless, the vast majority of patients retain dyspnea and impaired exercise capacity after angioplasty procedures. exercise training has been demonstrated to alleviate exercise dyspnea and to improve exercise capacity in many chronic cardiopulmonary conditions. pulmonary rehabilitation (rhb) can improve symptoms, quality of life and exercise capacity in patients with pulmonary vascular disease of different etiologies including cteph. furthermore, rhb does not present any particular risk for cteph patients with normalized or near-normalized pulmonary hemodynamics. unfortunately, access to rhb remains a concern in many countries. tele-rehabilitation (trhb) has been shown feasible and effective some cardiac or pulmonary diseases. our hypothesis is that trhb may also be effective in cteph patients with normalized or near-normalized pulmonary hemodynamics after bpa treatment. this randomized controlled study aims at comparing the effects of trhb with the effects of simple advices regarding exercising in cteph patients with normalized or near-normalized pulmonary hemodynamics after bpa treatment.
