Fig 1 Changes in serum markers of myocardial injury after transcatheter aortic valve replacement (TAVR). Changes in (A) creatine kinase-myocardial band (CK-MB) and (B) cardiac troponin T levels within the 72 hours after TAVR in all patients, and (C, D) grouped according to the approach, transaortic (TAo [green lines]) and transapical (TA [red lines]). Values are expressed as median (25th to 75th interquartile range).

Fig 2 Degree of increase in (A) creatine kinase-myocardial band (CK-MB) and (B) cardiac troponin T levels after transcatheter aortic valve replacement (TAVR). Cardiac biomarker changes after TAVR are grouped according to the degree of CK-MB and cardiac troponin T increase in all patients (blue bars) and in the transaortic (TAo [green bars]) and transapical (TA [red bars]) approach groups.

Fig 3 Changes in serum markers of myocardial injury after transcatheter aortic valve replacement (TAVR) for the propensity-matched cohort. Changes in (A) creatine kinase-myocardial band (CK-MB) and (B) cardiac troponin T levels within the 72 hours after TAVR in the matched population according to the approach: transapical (TA [red lines]) versus transaortic (TAo [green lines]). Values are expressed as median (25th to 75th interquartile range).

Fig 4 Change (delta [Δ]) in left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS) after transcatheter aortic valve replacement (TAVR) according to the approach: transapical (TA [red bars]) versus transaortic (TAo [green bars]). (A) Changes in LVEF and (B) GLS between the baseline and 6- to 12-month echocardiography after TAVR for the overall population and for the propensity-matched cohort (panels C and D, respectively).

Fig 5 Myocardial injury and left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS) changes after transcatheter aortic valve replacement (TAVR). Relationship between the maximal increase in cardiac troponin T and (A) changes in LVEF and (B) in GLS after TAVR.
