BALLOON PULMONARY ANGIOPLASTY IMPROVES RIGHT VENTRICULAR (RV) ENERGETIC EFFICIENCY VIA THE IMPROVEMENT OF RV-PULMONARY ARTERY COUPLING IN PATIENTS WITH CHRONIC THROMBOEMBOLIC PULMONARY HYPERTENSION

Balloon pulmonary angioplasty (BPA) improves hemodynamics and functional capacity in patients with chronic thromboembolic pulmonary hypertension (CTEPH). However the impact of BPA on right ventricular (RV) function and energetic efficiency remains unknown. Although the pressure-volume relationship
