“…After analyzing the entire cohort for the differences between the two conditions (i.e., TAVI in patients with vs. without HCM), the authors performed a 3:1 propensity matching analysis in 2,430 patients who underwent TAVI without HCM and compared them with 810 patients who underwent TAVI in the presence of HCM. The AS/HCM cohort had a 7-fold higher incidence of in-hospital mortality, more than 4-fold increase in aortic dissection incidence, and more than 3-fold higher incidence of cardiogenic shock and vascular complications [5]. Due to the nature of data collection, important information is missing as the presence, severity, and type of LVOT obstruction (i.e., at rest or provoked), the presence and severity of mitral regurgitation, the type and size of the prosthetic valve implanted, and the long-term outcome.…”
