Echocardiographic changes after discontinuation of dasatinib.

After HSCT (total dasatinib use)	Tricuspid Regurgitation (TR)	TR velocity	Pressure gradient	Intravascular septum
0 months (4 mo)	Trivial	1.4 m/sec	4 mmHg
20 months (21 mo)	Mild	3.4 m/sec	47 mmHg	D
Discontinuation of dasatinib
After discontinuation	Tricuspid Regurgitation (TR)	TR velocity	Pressure gradient	Intravascular septum
4 days	Mild	3.4 m/sec	48.8 mmHg	B<C
11 days	Trivial	2.7–2.8 m/sec	29.6–31.6 mmHg	B<C
1 month	Trivial	2.7–2.8 m/sec	31.7 mmHg	B<C
3 months	Trivial	2.4 m/sec	24.3 mmHg	B, mild flat
6 months	Trivial	1.5 m/sec	No significant pulmonary hypertension	Almost normal
