Although it was concluded that these findings in any one patient did not “preclude a positive haemodynamic and clinical result”, these early observations became the foundation of our current understanding of the evolution of pulmonary hypertension and right heart failure, following the establishment of proximal vessel, occlusive organised thromboembolic disease [2, 3]. Despite the significance and role of the microcirculation in chronic thromboembolic pulmonary hypertension (CTEPH), our understanding of the histopathology remains rather rudimentary [4] and previously confined to descriptions of the precapillary pulmonary … ER -
