valve-in-valve/valve-in-ring implantations for degenerative post-surgical valves: results from the global valve-in-valve reg-istry.
Introduction: Left bundle branch pacing (LBBP) has emerged in recent years as a new pacing modality, providing patients with a narrower paced QRS than conventional pacing and stable pacing parameters. At the same time, there is a growing concern about the use of fluoroscopy in pacemaker implantations, given its harmful effects on both patients and operators. However, there are no prior experiences of zero-fluoroscopy in LBBP procedure. Methods:We conducted an observational prospective study recruiting consecutive patients that underwent zero-fluoroscopy LBBP pacemaker implantation. A 6-month follow-up visit was programmed for every patient. The main goal of our study was to assess the efficacy, feasibility, and safety of the procedure.Results: From January 2021 to February 2022, we included 10 patients, 8 males. The average age was 63 ± 4 years. The procedure was successful in all patients. We observed a significant reduction in paced QRS width compared with basal QRS width (149 ± 31.9 vs. 116 ± 15.6 ms, p = .02). All device parameters remained stable at 6-month follow-up: no significant differences in mean impedance (700.5 ± 136.4 vs.
Introducción y objetivos: La reestenosis de stents coronarios (RS) presentan altas tasas de necesidad de revascularización, y el balón farmacoactivo (BFA) presenta clase I (nivel de evidencia A) en su tratamiento. La eficacia de esta estrategia a muy largo plazo en pacientes no seleccionados es desconocida. Se pretende evaluar la eficacia del BFA en un registro de pacientes de la práctica clínica a muy largo plazo de seguimiento (5 años). Métodos: Registro retrospectivo de una cohorte formada por pacientes con RS tratados con BFA. El evento primario fue la tasa de revascularización de la lesión tratada (RLT) con BFA a 5 años. Se valoraron eventos secundarios según los criterios Academic Research Consortium-2. Resultados: Entre enero de 2010 y diciembre de 2013 se usó BFA de forma eficaz en 53 RS de 48 pacientes. Los pacientes presentaban edad avanzada (69,3 ± 11,8 años) y alta prevalencia de diabetes (55,8%). La tasa de RLT a 1 año fue del 9,4%, y del 20,8% a los 3 y 5 años. La tasa de RLT tardía (más allá del año de seguimiento) fue del 11,4%, tan solo en reestenosis de stent convencional. La RLT a 5 años no se asoció a diabetes (22,7 frente a 19,2%; p = 0,76) ni fue significativamente menor con el uso de balón de corte (12,5 frente a 24,3%; p = 0,47) o en reestenosis de stent convencional (20,6 frente a 21,1%; p = 0,96). No hubo casos de trombosis de stent definitiva/probable de la lesión tratada con BFA. Conclusiones: En una cohorte de la práctica clínica, el BFA para RS presenta una RLT a 5 años del 20,8%. La RLT tardía supone la mitad de los casos a lo largo del seguimiento, y se produce en RS convencional. La tasa de RLT parece estabilizarse a partir del tercer año de seguimiento. No se evidenció trombosis de stent de la lesión tratada con BFA.Palabras clave: Balón farmacoactivo. Reestenosis de stent. Revascularización de lesión tratada. year-effectiveness of paclitaxel drug-eluting balloon for coronary in-stent restenosis in a real-world registry ABSTRACTIntroduction and objectives: Coronary in-stent restenosis (ISR) is associated with a high target lesion revascularization rate, while the drug-eluting balloon (DEB) presents IA class level of evidence for its treatment. Nevertheless, very long-term outcomes of DEB for ISR in non-selected populations of patients are unknown. Our goal is to evaluate the very long-term (5 year) effectiveness of DEBs in a real-world registry. Methods: Retrospective registry from an ISR cohort treated with DEB. The primary outcome was the rate of target lesion revascularization (TLR) at 5 years. Secondary outcomes were evaluated according to the ARC-2 criteria. Results: From January 2010 through December 2013, 53 ISRs were treated using DEBs in 48 patients. Patients were old (69.3 ± 11.8 years-old) and 55.8% had diabetes. The rate of TLR at 1 year was 9.4%, and 20.8% at 3 and 5 years, respectively. The rate of late TLR (after the first year) was 11.4%, only after DEB for bare metal ISR. The 5-year TLR was not associated with diabetes (22.7% vs 19.2%; P = .76), and was not signi...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
