A study recently published on BMC Pulmonary Medicine compared baseline characteristics and short-term efficacy of pulmonary endarterectomy (gold standard for operable chronic thromboembolic pulmonary hypertension, removing thickened intima and organized thrombus from pulmonary arteries) vs. balloon pulmonary angioplasty (an option for inoperable chronic thromboembolic pulmonary hypertension, improving blood flow by dilating stenosed/occluded vessels without removing lesions), particularly focusing on resistance-compliance time and cardiac index.
From the data collected and analysed, the following conclusions were drawn:
- Both pulmonary endarterectomy and balloon pulmonary angioplasty improve pulmonary pressures and pulmonary vascular resistance in chronic thromboembolic pulmonary hypertension.
- Only pulmonary endarterectomy improves cardiac index and reduces resistance-compliance time, indicating superior enhancement of pulmonary vascular mechanics. Even more importantly, after pulmonary endarterectomy therapy the proportion of symptom-free was significantly higher than in the balloon pulmonary angioplasty group.
- Balloon pulmonary angioplasty did not change resistance-compliance time and cardiac index in the short-term follow-up period in chronic thromboembolic pulmonary hypertension.
