How would you diff b/w reverse remodelling and MV stenosis. Presented at recheck with mod severe pulmonary HT. Smll dog treated for chronic MVD stage C. US= LV under loading, FS > 50%, LAE remains significant. M e-vel is consistently 1.5m/s or higher but dec. time and press half time appear normal. E:A ratio around 1. Would LAE remain with aggressive medical Tx for MVD due to LA remodelling, LA compliance ,chronicity of MVD and ongoing reg. vol. compared to potential for LV to undergo reverse remodelling with Tx. Is stenosis seen much in min breed old dogs? Ls7 vid=2024. Tks!!
