RESUMEN
BACKGROUND: Concomitant mitral transcatheter edge-to-edge repair (M-TEER) and left atrial appendage closure (LAAC) showed to be a feasible approach to optimize the treatment of patients eligible for both procedures, but mid-term outcomes are unclear. METHODS: We retrospectively analyzed consecutive patients undergoing M-TEER and enrolled in the local prospective Getting Reduction of Mitral Insufficiency by Percutaneous Clip Implantation (GRASP) registry. We compared patients undergoing isolated M-TEER (n = 58, 58.5%) with those undergoing concomitant M-TEER and LAAC (n = 41, 41.5%) from January 2018 to December 2022. The primary endpoint was a composite of all-cause death, stroke or systemic embolism, hospitalization for heart failure, and bleeding at 1 year. The co-primary endpoint was procedural success. RESULTS: The primary endpoint was similar between patients undergoing concomitant M-TEER+LAAC or isolated M-TEER (Kaplan Meier (KM) estimates 36.6% vs. 44.8%; plog-rank = 0.75). Procedural success was also similar (92.7% vs. 94.8%; p = 0.69). At 1- year, minor bleeds were lower in patients undergoing concomitant M-TEER and LAAC (KM estimates 0.0% vs. 18.9%; plog-rank < 0.01). CONCLUSION: In patients with concomitant MR and AF and eligible for M-TEER and LAAC treatment, a combined approach of M-TEER and LAAC was as safe as an M-TEER-alone strategy and associated with lower minor bleeding at 1 year.
RESUMEN
STUDY OBJECTIVES: Few studies have analyzed the prevalence of isolated rapid eye movement sleep behavior disorder (RBD) giving different estimates. Aim of the study was to estimate the prevalence of isolated RBD in the city of Catania. METHODS: A 3-stage design was adopted. Participants attending the offices of general practitioners in the city of Catania were screened with the RBD Single Question Screen questionnaire (Stage I). Positive participants were interviewed by phone and, if suspected of RBD, were invited for clinical examination by a movement disorders specialist and a sleep specialist (Stage II). After the clinical examination, patients diagnosed as probable isolated RBD (pRBD) were invited to undergo a video polysomnography (Stage III) to confirm the diagnosis of definite RBD. RESULTS: A total of 1,524 participants were screened. Of these, 220 (14.4%) screened positive. One hundred forty-three of them were further screened by phone, of whom 75 were suspected RBD. Thirty-six patients were diagnosed as pRBD, giving a prevalence of 2.36% (95% confidence interval, 1.71-3.25). Twelve pRBD agreed to a video polysomnography and, of these, 4 were diagnosed as definite RBD, giving a prevalence of 0.26% (95% confidence interval, 0.07-0.67). Prevalence adjusted by nonparticipants was 3.48% (95% confidence interval, 2.67-4.52) and 1.18% (95% confidence interval, 0.45-1.37) for pRBD and definite RBD, respectively. CONCLUSIONS: Prevalence of both pRBD and definite RBD in Italy is comparable to the estimates reported in literature, confirming that isolated RBD has a low prevalence in the general population.
