Limitations
HAVB, TAVR
Our study may have some limitations. First, it is a monocenter prospective study with a limited number of patients undergoing TAVR. Second, the HAVB rate necessitating PPM implantation of 7% was relatively low. Forty-four screened patients could not be included due to incomplete EP study. Further, the EP study was performed during the index procedure after deploying the valve prosthesis, but the conduction after TAVR might change, especially within the first 24 h [Of note, HAVB may occur immediately but also later involving inflammatory processes in addition to mechanical injury caused by valve expansion in the outflow tract [
