Objective: The aim of this study was to assess the rate of pacemaker use in patients who received TAVI with conventional coplanar technique compared with cusp-overlap technique. Methods: A total of 65 consecutive patients from two centers receiving Evolut-R or Evolut-Pro valve implantation, 50 coplanar and 15 cusp-overlap, were analyzed between 2017 and 2019. Results: Mean age was 80 years, and there were no differences in risk according to the EuroSCORE. The rate of pacemaker requirement was 0% in cusp-overlap procedures compared with 24.9% in those with conventional implantation; p=0.041). In addition, cusp-overlap implants presented lower rate of major complications (6.67% vs. 42%; OR=0.09; 95% CI 0.01-0.8; p=0.011). Conclusi...

Los puntajes de riesgo podrian ser utiles para determinar el pronostico, sin embargo no existen datos acerca de su utilidad en Argentina. Objetivo: Describir las caracteristicas clinicas de los pacientes sometidos a IVAP en un centro de alta complejidad, y evaluar la mortalidad a corto plazo en funcion de los diferentes puntajes de riesgo. Material y metodos: Registro unicentrico prospectivo de pacientes sometidos a IVAP desde el ano 2009 hasta 2016. Se describen las caracteristicas de la poblacion, la tecnica implementada y los eventos hospitalarios y a 30 dias. Se evaluo la relacion entre la mortalidad y los puntajes de riesgo quirurgico Euroscore logistico, Euroscore II, STS-PROM, y Observant. Resultados: Se incluyeron 88 pacientes consecutivos con un promedio de edad de 80 anos (+/-6,68) siendo 43% de sexo masculino. En el ...

The therapeutic target in the acute phase of STEMI is achieving rapid and permanent restoration of epicardial blood flow with subsequent improvement in myocardial tissue perfusion. (1) Several studies have demonstrated the superiority of primary percutaneous coronary intervention (PCI) over fibrinolytic therapy (FT) when this strategy can be implemented within a reasonable time. (1, 2) However, in our country most patients seek medical care at centers without PCI facilities. These centers choose to administer early FT to achieve rapid reperfusion, as the administration of FT within 3 hours after symptom onset is a favorable strategy and probably equivalent to primary PCI. (3, 4) Fibrinolytic therapy, however, has limitations, even if the best thrombolytic agent currently available is used (r-TPA accelerated infusion). Approximately 20% of patients do not achieve succes...

Los procedimientos conla tecnica de Cusp-Overlap presentaron 0% de requerimiento de marcapasos en comparacion con 24,9% en el implante convencional(p = 0,041). Tambien hubo menos complicaciones mayores (6,67% vs 42%; OR = 0,09; IC 95% 0,01-0,8; p = 0,011).Conclusio...
