A study from Karl Landsteiner University analyzed over 1,100 patients who underwent transcatheter aortic valve implantation (TAVI) and found that pacemaker implantation due to electrical conduction disturbances has different prognostic impacts on survival depending on patient sex. The research examined both short-term and long-term survival outcomes, revealing clear sex-based differences in how pacemakers affect post-procedure prognosis. These findings suggest that risk assessment protocols before and after TAVI procedures should be more individualized based on patient sex.


As TAVI procedures are increasingly performed on younger patients, understanding sex-specific differences in pacemaker outcomes becomes critical for improving patient selection, risk stratification, and post-operative management. This research could lead to more personalized clinical decision-making and potentially better survival outcomes through tailored treatment approaches for male and female patients.

Following transcatheter aortic valve implantation (TAVI), disturbances in the heart’s electrical conduction system can make a pacemaker necessary. A recent study shows that the significance of a pacemaker for subsequent prognosis differs between women and men. Physicians at Karl Landsteiner University (klu Krems) analyzed short- and long-term survival data from more than 1,100 people affected. The analysis revealed clear differences between women and men, suggesting that a more individualized assessment of risks before and after the procedure may be beneficial. This is becoming increasingly relevant as TAVI is also being used more frequently in younger people.
