- 07:07Conclusion
We present a protocol to induce and phenotype an acute right heart failure in a large animal model with chronic pulmonary hypertension. This model can be used to test therapeutic interventions, to develop right heart metrics or to improve the understanding of acute right heart failure pathophysiology.
