Left Ventricular Outflow Tract Morphology as a Predictor of Conductance Disturbances Following Transcatheter Aortic Valve Replacement.

Background: Conduction disturbances represent one of the most common complications following transcatheter aortic valve replacement (TAVR). We sought to investigate the role of left ventricular outflow tract (LVOT) morphology in the development of conduction disturbances following TAVR.

Methods And Results: Consecutive patients who underwent TAVR in our center were included.

Aortic angle distribution and predictors of horizontal aorta in patients undergoing transcatheter aortic valve replacement.

Background: Horizontal aorta (HA) is an anatomical feature that can pose significant technical challenges for the successful positioning of the bioprosthetic valve during transcatheter aortic valve replacement (TAVR). Physiological range of aortic angle (AA) is unknown; hence there is no cutoff AA for classifying HA. Moreover, patient characteristics predicting HA are under-investigated.

Reperfusion therapy of myocardial infarction in Mexico: A challenge for modern cardiology.

Mexico has been positioned as the country with the highest mortality attributed to myocardial infarction among the members of the Organization for Economic Cooperation and Development. This rate responds to multiple factors, including a low rate of reperfusion therapy and the absence of a coordinated system of care. Primary angioplasty is the reperfusion method recommended by the guidelines, but requires multiple conditions that are not reached at all times.
