Right Ventricular Stroke Work Index and Its Prognostic Value in a Lung Transplant Population With Group 3 Pulmonary Hypertension
By Marquet Y, Jacqmin S, Fessler J and 3 others.
Abstract
Background
Lung transplantation requires meticulous preoperative assessment. Recipients with Group 3 pulmonary hypertension can be at higher risk of mortality and primary graft dysfunction (PGD). We conducted a study to determine whether the right ventricular stroke work index (RVSWI), a right-heart catheterisation haemodynamic indicator assessing right ventricle function, could predict 1-year survival in this setting.
Methods
Monocentric, retrospective, observational cohort study approved by our local ethics review board, between January 2013 and December 2023. We included lung transplant recipients who underwent preprocedural right-heart catheterisation assessment and presented with Group 3 pulmonary hypertension. We first determined a clinically relevant RVSWI threshold. The primary endpoint was mortality at 1 year amongst two groups of patients according to this threshold.
