The PVRI Lung Transplantation in Pulmonary Hypertension Workstream presented a patient-focused webinar on debunking myths of lung transplantation. The areas covered included transplant evaluation, outcomes, and the experience of patients.
We present the case of an 18-year-old woman with a 5-day history of thoracic pain and dyspnea following physical exertion, along with swelling of her right calf. Computertomography (CT) angiography confirmed a massive central pulmonary artery embolism (PE) of the left main branch.
One of the great diagnostic challenges for children with pulmonary arterial hypertension is the need for general anesthesia (GA) to enable successful right heart catheterization.
Chronic thromboembolic pulmonary hypertension (CTEPH) is marked by persistent blood clots in pulmonary arteries, leading to significant morbidity and mortality. Emerging evidence highlights the role of microRNAs (miRNAs) in pulmonary hypertension, though findings on miRNA expression in CTEPH remain limited and inconsistent.
Recommended therapies for pulmonary arterial hypertension (PAH) have until recently targeted pathways with predominant effects of pulmonary vasodilation.1 The recent addition to treatment options of sotatercept, an activin signaling inhibitor which rebalances pro- and antiproliferative signaling, bolsters a longstanding goal of targeting pathogenic pulmonary vascular remodeling.
Tuberculosis (TB) may cause significant long-term cardiorespiratory complications, of which pulmonary vascular disease is most under-recognized. TB is rarely listed as a cause of pulmonary hypertension (PH) in most PH guidelines, yet PH may develop at various stages in the time course of TB, from active infection through to the post-TB period.
Pulmonary arterial hypertension affects females more frequently than males, and there are known sex-related differences in the lungs. However, normal sex-related differences in pulmonary vascular structure remain incompletely described.
Tricuspid annular plane systolic excursion (TAPSE) is usually measured with M-mode using sector line, however, this may not align with the anatomical shortening of the right ventricular (RV). In this study, we compared the different methods to measure TAPSE using three different reference lines (sector line, anatomical line, and apico-annular line).
Balloon pulmonary angioplasty (BPA) to treat chronic thromboembolic pulmonary hypertension (CTEPH) is generally reserved for distal obstruction precluding pulmonary endarterectomy (PEA) but can be used in patients with proximal disease who are at high surgical risk or refuse surgery. This single-center retrospective study compared BPA efficacy in patients with proximal versus distal CTEPH.
Webinar presentations: Autophagy and BMPR2 receptor degradation as the cause of PAH; BMPR1A promotes ID2-ZEB1 interaction to suppress endothelial to mesenchymal transition in PAH; Cardiovascular and pulmonary phenotypes for single and double knockout mice deficient in BMP9 and BMP10; BMPR2 – When and where the animal models match patient disease
