Similar valvotomy techniques yield comparable MVA gains; should not change practice and leaves open need for randomized trials.
Does instrumental valvotomy improve mitral valve area compared to digital valvotomy in patients with mitral stenosis?
Instrumental and digital closed mitral valvotomy yield similar average increases in mitral valve area at 1 year, with better outcomes observed in younger, female patients in sinus rhythm.
Gobel et al. (1969) studied this question.
