In recent decades, the advances in the management of functional mitral regurgitation (MR), makes knowledge of this disease extremely important to the clinical cardiologist, as it has an increasing prevalence in patients older than 50 years. The objective of this article is to review the pathophysiological bases of MR, in order to differentiate its mechanism, and to correlate them with the clinical, hemodynamic, and imaging findings that assess the severity of the disease. These data are relevant for the adequate selection of the patient and the opportune moment of the therapeutic interventions, which involves a multidisciplinary team in decision-making to achieve the greatest benefit within the treatment options of this pathology.

Los avances en el manejo de la insuficiencia mitral (IM) funcional en las últimas décadas, hacen que el conocimiento de la misma sea de suma importancia para el cardiólogo clínico, al tener una prevalencia cada vez mayor en pacientes mayores de 50 años. Esta revisión tiene como objetivo dar a conocer de una manera integral las bases fisiopatológicas de la IM para diferenciar sus mecanismos, y correlacionarlos con los hallazgos clínicos, hemodinámicos y de imágenes que valoran la severidad de la enfermedad. Estos datos son relevantes para la adecuada selección del paciente y del momento oportuno de las intervenciones terapéuticas, lo cual involucra a un equipo multidisciplinario en la toma de decisiones para lograr el mayor beneficio dentro de las opciones de tratamiento de esta patología.

The definition of high-risk chronic coronary syndrome varies depending on the noninvasive test used to trigger ischemia. The triggering occurs through increased myocardial work and oxygen demand, either through exercise or drugs. The initial approach to the chronic coronary syndrome leads us to discuss in which cases to prioritize an optimal initial medical therapy or to perform an initial invasive procedure of myocardial revascularization. In this article we analyze both approaches based on previous studies carried out to date, where the initial invasive management has not been shown to be superior to initial optimal medical therapy in outcomes such as death or major adverse cardiovascular events.

La definición de síndrome coronario crónico de alto riesgo varía según la prueba no invasiva empleada para evidenciar isquemia, lo que se consigue a través de un aumento del trabajo miocárdico y la demanda de oxígeno, generados con el uso de fármacos o el ejercicio. El abordaje inicial nos sumerge en la discusión de contextualizar en qué casos priorizar la terapia médica óptima inicial, frente al manejo invasivo inicial con el objetivo de lograr la revascularización miocárdica. Este aspecto central será desarrollado en esta revisión, tomando en cuenta diversos estudios realizados hasta la fecha, en los que el manejo invasivo inicial no ha demostrado ser superior a la terapia médica óptima inicial en resultados clínicos relevantes como muerte o eventos adversos cardiovasculares mayores.

  Background. ST-segment elevation myocardial infarction (STEMI), is an important cause of morbidity and mortality worldwide, and myocardial reperfusion, when adequate, reduces the complications of this entity. The aim of the study was to describe the clinical and treatment characteristics of STEMI in Peru and the relationship of successful reperfusion with in-hospital adverse events. Materials and methods. Prospective, multicenter cohort of STEMI patients attended during 2020 in public hospitals in Peru. We evaluated the clinical, therapeutic characteristics and in-hospital adverse events, also the relationship between successful reperfusion and adverse events. Results. A total of 374 patients were included, 69.5% in Lima and Callao. Fibrinolysis was used in 37% of cases (pharmacoinvasive 26% and alone lysis 11%), primary angioplasty with < 12 hours of evolution in 20%, late ang...

La combinación de regurgitación valvular aórtica, aortitis y estenosis sub aórtica no es frecuente en pacientes con artritis reumatoide. Además, el tratamiento quirúrgico de estas entidades puede ser desafiante y con resultados inadecuados. En este trabajo reportamos el caso de una paciente con regurgitación aórtica severa, raíz aórtica de inaccesible abordaje secundaria a aortitis reumatoide, y estenosis sub aórtica tratada en primera instancia con reemplazo valvular aórtico. Reoperamos a la paciente debido a una falla protésica aguda y se efectuó una reconstrucción valvular aórtica con pericardio bovino siguiendo la técnica de Ozaki con buenos resultados
