Objective: The aortic valve replacement is a routine procedure with acceptable risk, but in some cases, such a risk can justify contraindication. The minimally invasive transcatheter aortic valve implantation has been viable, with lower morbidity and mortality. The aim of this study was to develop a national catheter-mounted aortic bioprosthesis for the aortic position implant.Methods: After animal studies, 14 patients with high EuroSCORE underwent transcatheter aortic valve implantation. Median Logistic EuroSCORE was 43.7%. Four patients presented with dysfunctional bioprosthesis, remaining ones presented calcified aortic stenosis. All patients presented symptoms. Procedures were performed in a hybrid OR under fluoroscopic and echocardiography guidance. Using a left minithoracotomy the prosthesis was implanted through the ventricular apex under ventricular pacing or hemorrhagic shock, after aortic valvoplasty. Echocardiograph and angiograph controls were performed, and the patients were referred to ICU.Results: Implant was feasible in 13 cases. There were no intra-operative deaths. Rev Bras Cir Cardiovasc 2010; 25(3): 293-302 treatment. The survival rate with the technique was not satisfactory with a mortality rate of 65% at 1 year. Only 40% of patients at 1 year were free of reintervention, aortic valve replacement surgery, heart block, or death [6].
