Abstract
BackgroundThere are scarce data regarding mitral transcatheter edge-to-edge repair (TEER) in individuals aged 90 years and older. We aimed to evaluate patient characteristics, procedural aspects, and outcomes in this rapidly growing group. MethodsWe retrospectively studied a single-centre database of 967 isolated, first-time interventions, 103 (10.7%) of which were performed in nonagenarians. Outcomes included all-cause mortality, heart failure (HF) hospitalizations, and the persistence of significant mitral regurgitation (MR) or New York Heart Association functional class III/IV during the first postprocedural year. Analyses were repeated on a 204-patient, propensity score-matched subcohort, controlling for MitraScore elements, sex, race, MR etiology, functional status, atrial fibrillation/flutter, and procedural urgency. ResultsCompared with subjects below 90 years of age, nonagenarians were more likely to be White women of higher socioeconomic status; had a higher interventional risk, driven mainly by age and chronic kidney disease; presented more often with primary MR (71.8 vs 39.1%, P < 0.001); and exhibited less advanced biochemical/echocardiographic indices of cardiac remodelling. Further, their procedures were more commonly nonurgent and used fewer devices. A similarly high (> 97%) technical success rate was achieved in the 2 study groups. Likewise, no intergroup differences were observed in the rates or cumulative incidences of any of the explored endpoints, and neither of the outcomes’ risks was associated with age 90 and above. Comparable outcomes were also noted in the propensity score-matched subgroups. ConclusionsIn our experience, mitral TEER was equally feasible, safe, and efficacious in patients below and above 90 years of age.
