	TMT	HCM	P Value
LVWT (mm)	6.8 (6.0–9.7)	8.1 (6.0–12.3)	0.001
LA/Ao	1.8 (1.6–2.3)	2.4 (1.6–3.4)	<0.0001
Papillary muscle hypertrophy (% yes)	13/21 (62%)	14/21 (67%)	.75
Symmetric wall thickening (%yes)	20/21 (95%)	16/21 (76%)	.18
SAM (% yes)	6/21 (29%)	6/21 (29%)	1.0
Pericardial effusion (% yes)	9/21 (43%)	8/21 (38%)	0.5
SEC (% yes)	4/21 (19%)	8/21 (38%)	0.3

LVWT, left ventricular wall thickness; LA/Ao, left atrium to aorta ratio; SAM, systolic cranial motion; SEC, spontaneous echocardiographic contrast.
