Selective echocardiographic variables at presentation and final echocardiographic examination in cats with TMT and HCM

	TMT		HCM
	Initial Echo	Final Echo	Initial Echo	Final Echo
LVWT (mm)	6.8 (6.0–9.7)	4.8 (2.8–5.3)	8.1 (6.0–12.3)	7.9 (5.5–11)
LA/Ao	1.8 (1.6–2.3)	1.45 (1.2–1.7)	2.4 (1.6–3.4)	2.6 (2.0–5.3)
LAFS%	17 (4.3–21)	27 (15–49.6)	8.6 (0.9–17)	9 (1.7–16)

Cats with TMT showed a marked and clinically significant decrease in LVWT and LA size over time. LA/Ao, left atrium to aorta ratio; LVWT, left ventricular wall thickness; LAFS%, left atrial fractional shortening; LVWT, left ventricular wall thickness.
