The underlying cause was severe dynamic mitral regurgitation (MR) and secondary tricuspid regurgitation. After successful extubation and weaning, the patient\u2019s MR nearly resolved. Discharged in improved condition with guideline-directed medical therapy, the patient was soon readmitted for heart failure with pulmonary oedema. The transthoracic echocardiogram confirmed recurrent, worsening MR. Transcatheter edge-to-edge repair was successfully performed, reducing the patient\u2019s severe MR to trivial and resolving tricuspid regurgitation completely. At 1-year follow-up, the patient remained stable with improved cardiac function and no readmissions for cardiac causes.<\/jats:p>","DOI":"10.1093\/eschf\/xvaf014","type":"journal-article","created":{"date-parts":[[2026,1,8]],"date-time":"2026-01-08T09:02:15Z","timestamp":1767862935000},"source":"Crossref","is-referenced-by-count":0,"title":["Paroxysmal
