Outcome of isolated aortic valve replacement in patients with classic and paradoxical low-flow, low-gradient aortic stenosis.
To analyze operative outcomes and mid-term results after isolated aortic valve replacement (AVR) in low-flow, low-gradient aortic stenosis (LFLG AS) by comparing the 2 subcategories (classic low-flow, low-gradient aortic stenosis [CLFLG] and paradoxical low-flow, low-gradient aortic stenosis [PLFLG]). ⋯ AVR can be performed in LFLG AS with low in-hospital mortality. CLFLG AS carries similar in-hospital mortality to PLFLG AS but greater mid-term mortality. Surgery provided excellent functional status among survivors.
