Weight analysis at the 4th and 8th week after the PAB procedure.

(a) Weight analysis at the 4th week after the procedure

	BW	HW/BW	RV/BW	RV/(LV + IVS)
	(g)	ratio (mg/g)	ratio (mg/g)	ratio
Sham	435 ± 39	3.57 ± 0.16	0.56 ± 0.07	0.21 ± 0.02
PAL	403 ± 21	4.65 ± 0.17^∗	1.40 ± 0.13^∗	0.50 ± 0.04^∗
PAC	398 ± 33	4.88 ± 0.17^∗	1.39 ± 0.03^∗	0.49 ± 0.04^∗

(b) Weight analysis at the 8th week after the procedure

	BW	HW/BW	RV/BW	RV/(LV + IVS)
	(g)	ratio (mg/g)	ratio (mg/g)	ratio
Sham	508 ± 41	3.30 ± 0.23	0.48 ± 0.04	0.21 ± 0.01
PAL	505 ± 47	4.34 ± 0.30^∗	1.27 ± 0.12^∗	0.54 ± 0.02^∗
PAC	450 ± 50	4.81 ± 0.32^∗	1.40 ± 0.07^∗	0.58 ± 0.03^∗

There was no significant difference between the PAL and PAC groups.
BW: body weight at the sacrifice time, HW: heart weight, and ∗: versus sham.
