Table 7 Parameters of RA and RV in comparison among two groups

From: Comparison of the early cardiac electromechanical remodeling following transcatheter and surgical secundum atrial septal defect closure in adults

	Group 1 (device closure) (n = 15)	Group 2 (surgical closure) (n = 15)	P value
RA maximum volume (ml/mm²)
Before closure	74.53 ± 23.98	81.90 ± 30.07	0.46
After closure	46.88 ± 12.77	55.38 ± 18.03	0.14
Percentage of change	(−) 34.38 ± 17.47	(−) 30.15 ± 17.11	0.50
RV-EDV (ml/mm²)
Before closure	133.33 ± 25.26	152.33 ± 52.36	0.21
After closure	87.10 ± 14.08	106.60 ± 31.21	0.03
Percentage of change	(-) 32.60 ± 13.55	(−) 27.20 ± 15.07	0.31

RA right atrium, RVEDV right ventricle end diastolic volume. Data expressed as frequency (percentage), mean (SD). P value was significant if < 0.05
