We investigated whether normalization of pulmonary artery wedge pressure (PAWP) in response to sodium nitroprusside (SNP) during baseline right heart catheterization might be predictive of a favourable haemodynamic response to MitraClip in patients with FMR and PH. Among 22 patients enrolled, 13 had a positive response to SNP (responders), nine were non-responders. At 6-months follow-up, responders showed a 33% reduction in PAWP and a 25% reduction in mean pulmonary artery pressure (PAP) (P\u2009=\u20090.002 and 0.004, respectively); no significant change occurred in non-responders. In patients with FMR and PH, pre-procedural vasodilator challenge with SNP may help define patients who may have haemodynamic improvement after TEER.<\/jats:p>","DOI":"10.1093\/ehjacc\/zuac053","type":"journal-article","created":{"date-parts":[[2022,4,26]],"date-time":"2022-04-26T15:28:23Z","timestamp":1650986903000},"page":"464-469","source":"Crossref","is-referenced-by-count":3,"title":["Response
