Late-onset prosthetic aortic valve stenosis caused by pannus formation.
Journal of Cardiology Cases 2024 March
UNLABELLED: Transcatheter aortic valve replacement (TAVR) is a less invasive alternative to an open surgical aortic valve replacement (SAVR) for treating severe symptomatic aortic stenosis. Despite gaining widespread acceptance and approval for use in patients with high, moderate, and low surgical risk, the increasing use of TAVR has raised concerns about potential short- and long-term complications. We present the case of a 69-year-old female who underwent TAVR and subsequently presented to our outpatient cardiology clinic with progressively worsening dyspnea, orthopnea, and paroxysmal nocturnal dyspnea two years after the procedure. Echocardiography and stress testing revealed a recurrence of aortic stenosis, leading to a diagnosis of structural valve deterioration. The patient was subsequently scheduled for SAVR, which revealed commissural fusion, scarring, and unusual pannus formation that significantly narrowed the effective valve area, necessitating valve replacement. Despite requiring SAVR, two years after TAVR, the patient had a favorable postoperative course and outcome on follow-up. This case underscores the importance of continued surveillance and evaluation of patients who undergo TAVR, as they remain at risk for long-term complications such as structural valve deterioration. Proper management, including timely diagnosis and intervention, can lead to successful outcomes in such patients.
