Surgical protocol for pulmonary artery banding in mice to generate a model of pressure-overload-induced right ventricular failure

Right ventricular failure (RVF) is the leading cause of death in patients with pulmonary hypertension. Here, we present a protocol for pulmonary artery banding in mice to generate a model of pressure-overload-induced RVF. We describe steps for anesthesia of mice, endotracheal intubation, and pulmonary artery banding surgery. We then detail procedures for phenotyping and analysis. Our approach does not involve complete blockage of the pulmonary flow during clip placement and is, therefore, associated with low intraoperative mortality. For complete details on the use and execution of this protocol, please refer to Veith et al. (2020).(1).
