Assessing heart function during balloon treatment for pulmonary hypertension

Use of Right Ventricular Conductance Catheter Guidance to Optimise Balloon Pulmonary Angioplasty as a Non Surgical Treatment of Chronic Thromboembolic Pulmonary Hypertension.

Papworth Hospital NHS Foundation Trust · NCT04444973

This study is testing how balloon treatment for a specific type of lung high blood pressure affects heart function in patients who can’t have surgery.

What this trial studies

This observational study focuses on patients with inoperable chronic thromboembolic pulmonary hypertension (CTEPH) undergoing balloon pulmonary angioplasty (BPA). The researchers aim to measure right ventricular pressure volume loops and biomarkers during the procedure to better understand the relationship between right heart function and treatment outcomes. By analyzing these data, the study seeks to develop non-invasive methods for assessing the effectiveness of BPA and pulmonary endarterectomy. This could lead to improved patient selection and treatment strategies for those suffering from CTEPH.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old with inoperable CTEPH who are eligible for BPA treatment.

Not a fit: Patients with severe co-morbidities, significant left to right shunts, or other specific exclusions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the ability to predict which patients will benefit from balloon pulmonary angioplasty, leading to better treatment outcomes.

How similar studies have performed: While the approach of using non-invasive assessments is promising, this specific methodology has not been widely tested in similar studies.
