Gliederung

Text

Introduction: Transseptal (TSA) and transapical (TAA) antegrade access for stentgraft deployment in the ascending aorta is feasible in a porcine model. The aim of this study was to test the technical feasibility of a single sidebranch arch endograft in a porcine model with TSA or TAA for catheterization and introduction of the mating stentgraft.

Material and methods: Domestic pigs (n=6) were operated with retrograde delivery of a single-sidebranch arch endograft and antegrade introduction of a mating stentgraft using TSA (n=3) and TAA (n=3). Technical feasibility, operating time, radiation parameters and hemodynamic changes were studied.

Results: TSA and TAA was feasible in all animals. Catheterization and introduction of the mating stentgraft was feasible in two of three animals in the TSA group and all animals in the TAA group. Technical feasibility was better in the TAA group with shorter operating and fluoroscopy time and less hemodynamic changes during endograft deployment. Hemodynamic changes were short and reversible in all animals in both groups.

Conclusion: Antegrade transcardiac access to the aortic arch for implantation of mating stent-grafts in branched arch endografting is feasible in a porcine model with reversible impact on hemodynamic measures during deployment. TAA was technically easier with shorter operating and fluoroscopy times.
