Answer

Five-year outcomes from the PARTNER trial showed similar outcomes between high-risk patients with aortic stenosis who underwent TAVR and those who underwent surgical aortic valve replacement (SAVR). [38] At 5 years, risk of death was 67.8% in the TAVR group versus 62.4% in the SAVR group. Neither group reported structural valve deterioration requiring surgical valve replacement. However, moderate or severe aortic regurgitation occurred in 40 of 280 (14%) patients in the TAVR group but in only 2 of 228 (1%) patients in the SAVR group; this was associated with increased 5-year risk of mortality in the TAVR group.
