Cusp thrombosis of a self-expandable sutureless aortic valve treated by valve-in-valve transcatheter aortic valve implantation procedure: case report.

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.

Project description:BackgroundConduction disturbances demanding permanent pacemaker implantation (PPI) remain a common complication after transcatheter aortic valve replacement (TAVR). Optimization of the implantation depth (ID) by introducing the cusp-overlap projection (COP) technique led to a reduced rate of PPI when self-expanding valves were used.ObjectivesThe aim of the present study was to determine if using the novel COP view is applicable for all types of TAVR prosthesis and results in a higher ID and reduced incidence of new conduction disturbances and PPI.MethodsIn this prospective case-control study 586 consecutive patients undergoing TAVR with either balloon-expandable Edwards SAPIEN S3 (n = 280; 47.8%), or mechanically expandable Boston LOTUS Edge heart valve prostheses (n = 306; 52.2%) were included. ID as well as rates of periprocedural PPI and left bundle branch block (LBBB) were compared between the conventional three-cusp coplanar (TCC) projection and the COP view for implantation.ResultsOf 586 patients, 282 (48.1%) underwent TAVR using COP, whereas in 304 patients (51.9%) the TCC view was applied. Using COP a significantly higher ID was achieved in Edwards SAPIEN S3 TAVR procedures (ID mean difference -1.0 mm, 95%-CI -1.9 to -0.1 mm; P = 0.029), whereas the final platform position did not differ significantly between both techniques when a Boston LOTUS Edge valve was used (ID mean difference -0.1 mm, 95%-CI -1.1 to +0.9 mm; P = 0.890). In Edwards SAPIEN S3 valves, higher ID was associated with a numerically lower post-procedural PPI incidence (4.9% vs. 7.3%; P = 0.464). Moreover, ID was significantly deeper in patients requiring PPI post TAVR compared to those without PPI [8.7 mm (6.8-10.6 mm) vs. 6.5 mm (6.1-7.0 mm); P = 0.005]. In Boston LOTUS Edge devices, COP view significantly decreased the incidence of LBBB post procedure (28.1% vs. 47.9%; P < 0.001), while PPI rates were similar in both groups (21.6% vs. 25.7%; P = 0.396).ConclusionThe present study demonstrates the safety, efficacy and reproducibility of the cusp-overlap view even in balloon-expandable and mechanically-expandable TAVR procedures. Application of COP leads to significantly less LBBB in repositionable Boston LOTUS Edge valves and a numerically lower PPI rate in Edwards SAPIEN S3 valves post TAVR compared to the standard TCC projection. The results should encourage to apply the COP view more widely in clinical practice.
