In recent years, heart valve disease has been increasing year by year. Transcatheter aortic valve replacement (TAVR) has become the first-line surgical method for patients with severe aortic stenosis due to the advantages of small surgical trauma and rapid postoperative recovery. In the context of the rapid development of TAVR, the postoperative complications of TAVR seriously affect the surgical success rate and patient prognosis. Therefore, the prevention and nursing of complications after TAVR are particularly important. This article will review the assessment, prevention and care of the complications such as arrhythmia, vascular complications, perivalvular leakage, stroke, and acute renal failure after TAVR in combination with the current situation at home and abroad, in order to enhance the clinical medical workers’ understanding of the complications.
