Cusp thrombosis of a self-expandable sutureless aortic valve treated by valve-in-valve transcatheter aortic valve implantation procedure: case report.
Ontology highlight
ABSTRACT: Background
Surgical implantation rates of bioprosthetic valves, especially the use of sutureless or rapid deployment valves, as well as the advent of transcatheter valve implantation (TAVR) have increased during the last decades mainly due to their excellent haemodynamic and clinical results. One common characteristic of all bioprosthetic types of surgical aortic valve replacement (SAVR) and TAVR is the risk of early degeneration, which leads to valve-dysfunction and is associated with higher rates of valve reinterventions. Recent studies have demonstrated that cusp thrombosis may play a role in early valve dysfunction. This case report is, to our knowledge, the first documentation on a successful treatment of early aortic valve (AV) degeneration of a sutureless AV thrombosis with a valve-in-valve (ViV) TAVR implantation.Case summary
A 77 years old woman was re-evaluated from the heart-team, which considered the following characteristics: severe impairment of mobility and frailty with an STS-score of 10.01% and a EuroSCORE II of 6.9%. Due to the high surgical risk for SAVR, we decided to perform a ViV-TAVR using a balloonexpandable bioprosthesis. The procedure was performed via transfemoral access under general anaesthesia using a 23 mm Edwards-Sapien 3 bioprosthesis without balloon-valvuloplasty and with nominal-volume dilation under rapid-pacing.Discussion
The differentiation of bioprosthesis valve thrombosis, and hypoattenuating leaflet thickening vs. structural valve degeneration can be difficult, and a multimodality imaging approach, comprising trans-thoracic echocardiogram, transoesophageal echocardiography and computed tomography, useful. These investigations are very important to decide the right strategy of surgical valve replacement vs. TAVR.
