Conduction Disturbances and Permanent Cardiac Pacing after Transcatheter Aortic Implantation (TAVI) – An Update Overview
Aortic valve replacement is a common treatment with a low risk of complications. In some circumstances, the surgery is contraindicated due to high mortality. Transcatheter aortic valve implantation appears to be a viable option for lowering morbidity and mortality. A bioprosthetic valve is inserted through a catheter and placed within the wounded native aortic valve in this technique. Despite the fact that the treatment is considered quite safe, there are risks of complications that have been identified by persons following the procedure, such as new-onset permanent left bundle branch block (LBBB) and the requirement for permanent cardiac pacing. A systematic evaluation of PUBMED literature was conducted using the criteria “10 years” and “free complete texts,” with the terms “TAVI,” “pacing,” and “complications” as search terms, yielding a total of eight articles. Other databases were used to provide context, consistency, and depth to the text, including SCIELO, Google Scholar, and MEDLINE. Aortic valve prosthesis implantation by catheter appears to be a viable option for individuals with aortic stenosis who are at high surgical risk. The findings of this group of patients imply that the necessity for a permanent pacemaker following endovascular therapy is not inevitable and is not easily anticipated by the risk variables discussed thus far. TAVI is the preferred procedure since it is both feasible and safe. Conduction issues are common because the valve prosthesis is implanted close to key septal cardiac structures, necessitating careful monitoring for at least seven days after the procedure. There is a lack of consensus and a lot of variation in the therapy of conduction abnormalities after TAVR. Future research is needed to evaluate the suggested approach and determine the significance of EP studies, ambulatory continuous ECG monitoring, and a prophylactic pacemaker in the treatment of post-TAVR conduction disturbances.
