          RESUMEN Introducción y objetivos: La estimulación ventricular rápida reduce el gasto cardiaco, proporcionando estabilidad durante el implante percutáneo de válvula aórtica (TAVI). Nuestro objetivo fue evaluar la eficacia y la seguridad de la estimulación ventricular izquierda a través de la guía de alto soporte utilizada para el implante y una guía situada en la aurícula derecha (AD) que actúa como ánodo. Métodos: La estimulación ventricular izquierda se realiza conectando el extremo externo de una guía Safari2 preformada situada en el ventrículo izquierdo al cátodo de un marcapasos temporal, y el ánodo al cuerpo de una guía Emerald insertada en la aurícula mediante un catéter Judkins Right diagnóstico a través de un acceso venoso femoral (punción ecoguiada). El marcapasos se programa con salida máxima (20 V) y sensibilidad anulada. Resultados: Se realizó TAVI transfemoral a 62 pacientes seleccionados (mediana de edad: 79,4 ± 6,5 años) utilizando la técnica de estimulación descrita (25 SAPIEN 3 Ultra, 13 Navitor, 9 ACURATE neo2, 14 Evolut-PRO+ y 1 Myvalve), con éxito en todos los casos (hubo 1 fallo de captura atribuido a la programación del generador del marcapasos). Dos pacientes necesitaron marcapasos transitorio y definitivo posterior por bloqueo auriculoventricular completo durante el procedimiento. No se documentaron complicaciones vasculares derivadas del acceso venoso ni del posicionamiento de la guía en la AD. No aumentaron de manera significativa el tiempo del procedimiento ni la fluoroscopia. La mediana de estancia hospitalaria tras el implante fue de 2 días. Conclusiones: En nuestra serie, la estimulación ventricular izquierda utilizando como ánodo la guía situada en la AD ha demostrado ser una técnica eficaz y segura, sin aumentar significativamente el tiempo de procedimiento, y además aporta la ventaja de disponer de acceso venoso central para un posible marcapasos transitorio urgente.

          ABSTRACT Introduction and objectives: Rapid ventricular pacing reduces cardiac output by providing stability during transcatheter aortic valve implantation (TAVI). Our objective is to assess the efficacy and safety profile of left ventricular pacing through the high-support guidewire used for implantation and a guidewire located in the right atrium (RA) functioning as an anode. Methods: Left ventricular pacing is performed by connecting the external end of a Safari2 pre-shaped guidewire located in the left ventricle to the cathode of a temporary pacemaker, and the anode to the body of an Emerald guidewire inserted into the RA using a diagnostic Judkins Right catheter (via ultrasound-guided femoral venous access). Pacemaker was programmed with maximum output (20 V) and null sensitivity. Results: A total of 62 selected patients (median 79.4 ± 6.5 years old) underwent transfemoral TAVI using the pacing technique described (25 patients the SAPIEN 3 Ultra; 13 the Navitor, 9 the ACURATE neo2, 14 the Evolut PRO+, and 1 patient the Myvalve). Procedure was successful in all cases (there was 1 capture failure due to pacemaker programming). Two patients required a temporary and permanent pacemaker due to high-grade atrioventricular block. No vascular complications from venous access were documented, not even from the RA guidewire. Procedural time did not increase significantly, and the median length of stay after implantation was 2 days. Conclusions: In our series, left ventricular pacing using the RA-positioned wire as the anode proved to be effective and safe without increasing procedural time significantly. This procedure also provides the advantage of being able to use the central venous access for possible emergency temporary pacemaker implantation.

          Transcatheter Aortic-Valve Replacement with a Balloon-Expandable Valve in Low-Risk Patients

          Among patients with aortic stenosis who are at intermediate or high risk for death with surgery, major outcomes are similar with transcatheter aortic-valve replacement (TAVR) and surgical aortic-valve replacement. There is insufficient evidence regarding the comparison of the two procedures in patients who are at low risk.

            Transcatheter Aortic-Valve Replacement with a Self-Expanding Valve in Low-Risk Patients

            Transcatheter aortic-valve replacement (TAVR) is an alternative to surgery in patients with severe aortic stenosis who are at increased risk for death from surgery; less is known about TAVR in low-risk patients.

              Transcatheter or Surgical Aortic-Valve Replacement in Intermediate-Risk Patients.

              Previous trials have shown that among high-risk patients with aortic stenosis, survival rates are similar with transcatheter aortic-valve replacement (TAVR) and surgical aortic-valve replacement. We evaluated the two procedures in a randomized trial involving intermediate-risk patients.
