OBJECTIVES We sought to determine whether an AVR performed though a partial upper hemisternotomy ("mini-AVR") resulted in a greater incidence of patient-prosthesis mismatch (PPM) than those through a full median sternotomy ("AVR"). METHODS Patients undergoing isolated aortic valve replacement from 2008 to 2013 were identified. Moderate PPM was defined as an in vivo effective orifice area ≤0.85 cm(2)/m(2) body surface area; severe PPM was defined as ≤0.65 cm(2)/m(2). A propensity score-matched… CONTINUE READING
