RESUMO

We aimed to compare the outcomes of transcatheter aortic valve implantation (TAVI) with surgical aortic valve replacement (SAVR) in an elderly but nonfrail, minimally co-morbid population. Although data comparing these 2 procedures in intermediate- and low-risk patients are mounting, no distinction has been made between co-morbidity and age/gender as driving forces for surgical risk. Patients undergoing isolated TAVI or SAVR between May 2008 and March 2015 were documented. Data for 225 patients (TAVI 132, SAVR 93) aged ≥75 and <86 years and fulfilling minimal-risk criteria were analyzed. Patients who underwent TAVI were older (80.7 vs 77.4 years, p <0.0001) and had a higher mean Society of Thoracic Surgeons score (2.16% vs 1.72%, p <0.0001). Mild prosthetic valve regurgitation (odds ratio [OR] 4.9, 95% confidence interval [CI] 3.34 to 7.20) was more likely after TAVI, as were renal complications (predominantly stage I acute kidney injury; OR 2.86, 95% CI 1.79 to 4.55) and new pacemaker implantation (OR 3.33, 95% CI 1.76 to 6.26) at 30 days; however, life-threatening bleeding (OR 0.58, 95% CI 0.36 to 0.93) and reintervention for bleeding (OR 0.03, 95% CI 0.01 to 0.13) were less likely. Survival was comparable between groups at 30 days (99.2% vs 100%, p = 1.0) and 1 year (96.2% vs 96.8%, OR 0.85, 95% CI 0.20 to 3.63, p = 0.823), but it was poorer for patients who underwent TAVI at 2 years (OR 0.31, 95% CI 0.16 to 0.61). In conclusion, the short-term outcomes of TAVI in elderly, low-risk, minimally co-morbid patients appear to be similar to those of SAVR, with access-specific complications. Although these results point toward the potential for more liberal use of TAVI in minimal-risk patients, poorer midterm survival remains a concern, requiring further exploration.
