OBJECTIVES: We aimed to evaluate early clinical and procedural outcomes with the 34-mm Evolut R transcatheter aortic valve replacement (TAVR) prosthesis.

BACKGROUND: The 34-mm Evolut R (Medtronic, Minneapolis, MN) self-expanding TAVR prosthesis was designed to treat patients with larger annuli.

METHODS: Clinical, demographic, procedural, and echocardiographic data on consecutive patients who underwent TAVR with a 34-mm Evolut R prosthesis at our institution were collected and analyzed.

RESULTS: One hundred ninety-six patients underwent TAVR with this prosthesis from November 2016 to July 2018, a majority (n = 188, 96%) through transfemoral access and with conscious sedation (n = 182, 93%). Mean age, Society of Thoracic Surgery risk score, and follow-up were 82 ± 8 years, 5.4 ± 5%, and 8.2 ± 5.3 months, respectively. Mean aortic valve (AV) peak velocity was 4.0 ± 0.6 m/s, mean AV gradient was 38 ± 13 mmHg, AV area was 0.79 ± 0.23 cm

CONCLUSION: These data demonstrate high success and good procedural, echocardiographic, and clinical outcomes of 34-mm Evolut R in patients with large annuli.
