Comparison between Cardiac CTA and Echocardiography for Assessment of Ventricular Septal Rupture Diameter and Its Effect on Transcatheter Closure

Table 5

Effect of different perforation sites and right ventricular surface obstruction on occluder.

Measurement index	Anterior septal perforation				Posterior septal perforation ()	value^b
	Overall ()	Right ventricular surface obstruction ()	No right ventricular surface obstruction ()	value^a
POD (mm)				<0.001		0.720
CTLD (mm)				0.029		0.370
POD-CTLD (mm)				0.004		0.594
Occluder diameter (mm)	24 (22, 26)	22 (20, 23)	26 (25, 27)	0.024	22 (18, 28)	0.663
CROWD				<0.001		0.902

Note: ^acomparison between with and without right ventricular surface obstruction intra-anterior septal group; ^bcomparison between anterior and posterior septal rupture. POD: postoperative occluder diameter; CTLD: long diameter of rupture measured by CTA; POD-CTLD: the different values between POD and CTLD; CROWD: compression rate of the occlude waist diameter.
