ABSTRACT
BACKGROUND: Coronary artery obstruction after percutaneous aortic replacement is a complication with high short-term mortality secondary to the lack of timely treatment. There are various predictors of coronary obstruction prior to valve placement such as the distance from the ostia, the degree of calcification, the distance from the sinuses; In such a situation some measures must be taken to prevent and treat coronary obstruction. CASE PRESENTATION: An 84-year-old male, with severe aortic stenosis and high surgical risk, who was treated with TAVR. However, during the deployment of the valve he presented hemodynamic instability secondary to LMCA obstruction. The intravascular image showed obstruction of the ostium secondary to the displacement of calcium that he was successfully treated with a chimney stent technique. CONCLUSIONS: The high degree of calcification and the left ostium near the annulus are conditions for obstruction of the ostium at the time of valve release; In this context, provisional stenting prior to TAVR in patients at high risk of obstruction should be considered as a safe prevention strategy to achieve the success of the procedure.

Abstract Objective: The purpose was to compare the outcomes of patients with ST-elevation myocardial infarction and multivessel coronary artery disease undergoing one-time multivessel revascularization (OTMVR) versus in-hospital staged complete revascularization with percutaneous coronary intervention. Methods: This was a single-center, retrospective, observational, and cohort study, including data from January 2013 to April 2019. A total of 634 patients were included in the study. Comparisons were made between patients who underwent in-hospital staged complete revascularization versus OTMVR. The primary endpoint was all-cause in-hospital mortality, secondary endpoints included cardiovascular complications, all-cause new hospitalization, and mortality evaluated at 30 days and 1 year. In addition, we constructed a logistic regression model for determining the risk factors that predicted mortality. Results: Of the 634 patients, 328 were treated with staged revascularization and 306 with OTMVR. About 76.7% were men, with a mean age of 63.3 years. Less complex coronary lesions and a higher proportion of the left anterior descending artery as the culprit vessel were found in the OTMVR group. Compared with staged revascularization, the primary and secondary endpoints occurred less frequently with OTMVR strategy. Conclusions: OTMVR did not generate more complications and demonstrate better clinical outcomes than in-hospital staged revascularization.
Resumen Objetivo: El propósito fue comparar resultados de pacientes con infarto agudo de miocardio con elevación del segmento ST y enfermedad coronaria multivaso sometidos a revascularización completa de un solo momento frente a revascularización completa por etapas mediante intervención coronaria percutánea. Métodos: Estudio cohorte observacional, retrospectivo, unicéntrico, con datos de enero de 2013 a abril de 2019, incluyendo 634 pacientes. Se compararon resultados entre pacientes sometidos a revascularización completa por etapas frente a revascularización completa en un solo momento. El objetivo primario fue valorar mortalidad intrahospitalaria por cualquier causa y como objetivos secundarios se evaluaron a 30 días y 1 año las complicaciones cardiovasculares, hospitalizaciones y mortalidad. Se construyó un modelo de regresión logística para determinar los factores de riesgo que predijeron mortalidad. Resultados: De 634 pacientes, 328 fueron tratados con revascularización por etapas y 306 con revascularización en una intervención. El 76.7% fueron hombres, con una media de edad de 63.3 años. En el grupo de revascularización de un solo tiempo se encontraron lesiones coronarias menos complejas y una mayor proporción de la arteria descendente anterior como vaso culpable. Comparado con el grupo de revascularización por etapas, los objetivos primarios y secundarios ocurrieron con menos frecuencia en el grupo de revascularización en un solo tiempo. Conclusiones: Comparada con la revascularización intrahospitalaria por etapas, la revascularización en una intervención lleva a mejores desenlaces clínicos sin generar más complicaciones.

The presence of moderate to severe paravalvular leak increases mortality. We present a case of giant paravalvular leak closure using the 3-dimensional printing model to assess the success of the device to be used for its closure, computed tomography was performed for planning and guiding the procedure by image fusion. (Level of Difficulty: Advanced.).
ABSTRACT
The presence of a horizontal aorta in patients treated with transcatheter aortic valve replacement increases the difficulty of the procedure. We present 5 cases with aortic stenosis with a horizontal aorta who underwent transcatheter aortic valve replacement using a self-expanding prostheses, with the objective of describing the techniques used and obtaining success with a snare catheter. (Level of Difficulty: Intermediate.).
ABSTRACT
Heart failure (HF) is the leading cause of death worldwide. Efforts to decrease HF mortality rates include a multidisciplinary approach management. Although evidence suggests that this has been an optimal strategy for treating HF, the model remains not widely implanted. The current article explores the rationale behind the formation of a Heart Team in a developing country and its development despite the lack of an allocated budget.
