Table 5 PAP and shunt fraction (QP/QS) in both groups

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

  Device closure
(n = 15)
Surgical closure
(n = 15)
P value
MPAP (mmHg)    
 Baseline 27.93 ± 5.18 30.67 ± 5.30 0.16
 Post-closure 18.13 ± 7.21 23.93 ± 6.63 0.03
QP/QS ratio    
 Before closure 2.03 ± 0.25 2.23 ± 0.40 0.11
 After closure 0.95 ± 0.13 1.04 ± 0.09 0.04
