Vericiguat and transcatheter edge-to-edge mitral valve repair for combined post- and pre-capillary pulmonary hypertension due to left ventricular low ejection fraction and functional mitral regurgitation.

ABSTRACT

A 66-year-old female was diagnosed with combined post- and pre-capillary pulmonary hypertension due to heart failure with reduced ejection fraction (47 %) and functional mitral regurgitation [mean pulmonary arterial wedge pressure 27 mmHg; pulmonary arterial pressure 91/30 (56) mmHg; pulmonary vascular resistance 12.9 Wood units; and cardiac index 1.77 L/min/m2]. Following treatment with vericiguat (a novel oral soluble guanylate cyclase stimulator), hemodynamics improved [mean pulmonary arterial wedge pressure 27 mmHg; pulmonary arterial pressure 54/26 (35) mmHg; pulmonary vascular resistance 2.2 Wood units; and cardiac index 2.80 L/min/m2]. Therefore, transcatheter edge-to-edge repair for functional mitral regurgitation was performed. One month later, further improvement in hemodynamics was confirmed. Learning objective: Vericiguat (a novel oral soluble guanylate cyclase stimulator) and transcatheter edge-to-edge mitral valve repair may improve combined post- and pre-capillary pulmonary hypertension due to low ejection fraction of the left ventricle and functional mitral regurgitation.
