How do long-term outcomes after aortic valve replacement compare between patients with and without low-gradient aortic stenosis, and what is the impact of patient-prosthesis mismatch (PPM)?
Patient-prosthesis mismatch should be avoided in patients with low-gradient aortic stenosis undergoing aortic valve replacement due to its adverse effect on long-term outcomes.
Patients with LGAS have worse long-term outcomes after AVR compared with patients without LGAS. PPM adversely affects the long-term outcomes of LGAS patients and should be avoided in this population.
