Risk for Permanent Pacemaker After TAVI
Risk for Permanent Pacemaker After TAVI
The present analysis comprises data from more than 5,000 patients undergoing TAVI. It demonstrates a substantial risk of postprocedural high-degree AV block with subsequent need for PM implantation. This risk seems considerably higher when CVP rather than ESP are used. Patients with preexisting RBBB are at higher risk and prophylactic PM implantation needs to be taken into consideration on a patient-by-patient basis. Because AV block occurs in more than 90% of cases within the first week after the procedure, careful monitoring should be performed for at least 7 days after TAVI.
