Goal: To evaluate the predictive factors of unfavorable results, such as mortality and major complications, in patients undergoing percutaneous aortic valve implantation. Methods: Cross-sectional study was performed at the Santa Catarina Institute of Cardiology (ICSC) and at the SOS Cardio Hospital. It was included sixty-five patients diagnosed with calcified aortic valve stenosis, in the period from January 2010 to June 2017. A descriptive and bivariate analysis was performed using the chi-square test (χ2) and logistic regression. The research was approved in ethical committee at UNISUL and at ICSC. Results: 56.9% were males, 60% had age equal or less than 85 years, 67.7% had diagnosed with coronary artery disease (CAD), 80% had hypertension, 44.6% had diabetes mellitus (DM), 20% with chronic obstructive pulmonary disease (COPD), 12.3% with previous stroke, 18.5% had previous acute myocardial infarction (AMI), 21.5% had previous cardiac surgery and 20% had aortic insufficiency associated. Complications and post-procedure mortality are relative to the hospital phase. Stroke occurred in 2 patients (3.1%), AMI with segment ST elevation in 1 (1.5%), mild aortic regurgitation in 41 (63.1%), moderate in 3 (4.6%) and severe in 1 (1.5%). Seventeen patients had some conduction disturbances (26.2%), and 10 (15.4%) of this required definitive pacemaker implantation. Major vascular complications in 8 (12.3%) and 9 (13.8%) patients died. Conclusion: There was no significant association between demographic and preoperative clinical characteristics with unfavorable results in patients undergoing percutaneous aortic valve implantation.Objetivo: Avaliar os fatores preditores de resultados desfavoráveis, como mortalidade e complicações maiores, em pacientes submetidos a implante percutâneo de valva aórtica. Métodos: Estudo observacional com delineamento transversal realizado no Instituto de Cardiologia de Santa Catarina (ICSC) e no Hospital SOS Cardio. Participaram do estudo 65 pacientes portadores de estenose valvar aórtica calcificada, de janeiro de 2010 a junho de 2017. Realizaram-se análise descritiva e bivariada, com teste qui-quadrado (χ2) e regressão logística. Aprovado no CEP UNISUL e ICSC. Resultados: Sexo masculino foi achado em 56,9% dos pacientes, idade igual ou menor de 85 anos em 60,0%, doença arterial coronária em 67,7%, hipertensão arterial sistêmica em 80,0%, diabetes mellitus em 44.6%, doença pulmonar obstrutiva crônica em 20%, Acidente Vascular Cerebral (AVC) prévio em 12,3%, Infarto Agudo do Miocárdio (IAM) prévio em 18,5%, cirurgia cardíaca prévia em 21,5 % e insuficiência aórtica associada em 20%. As complicações e mortalidade pós procedimento são relativas à fase hospitalar. O AVC ocorreu em 2 pacientes (3,1%), IAM com supra ST em 1 (1,5%), regurgitação aórtica discreta em 41 (63,1%), moderada em 3 (4,6%) e severa em 1 (1,5%). 17 pacientes apresentaram algum distúrbio de condução (26,2%), destes, 10 (15,4%) necessitaram de implante de marcapasso definitivo. Complicações vasculares maiores em 8 (12,3%) e pacientes que foram a óbito 9 (13,8%). Conclusão: Não houve associação significativa entre as características demográficas e clinicas pré procedimento com os resultados desfavoráveis nos pacientes submetidos ao implante percutâneo de valva aórtica.
