basal-interpapillary muscle distance (IPMD) diastolic-to-systolic ratio (DSR) (P = 0.008)
.
Among all TTE indices, LVEF, LVESV, and basal-IPMD DSR were helpful to differentiate between the successful and unsuccessful MVA results. We believe the basal-IPMD DSR as a novel index could be targeted in the future studies.
.
Of the total of 126 cases, 68 had successful and 58 had unsuccessful MVA.

Com uma taxa altíssima de insucesso, o procedimento deveria ser melhor analisado na seleção dos pacientes.
A distância entre os papilares é uma medida simples mas muito inteligente e funcional.
