Transcatheter Closure of Atrial Septal Defects in Children, Middle-Aged Adults, and Older Adults: Failure Rates, Early Complications; and Balloon Sizing Effects

Table 4

Comparison of ASD diameters, device sizes, device/diameter ratio, and procedural times in successful cases of patients who had TEE only or TEE with balloon sizing.

	TEE only (𝑛=151)	TEE with balloon sizing (𝑛=420)	𝑃 value	95% CI of the difference
ASD diameter (mm)	20.1±8.2	22.9±6.9	<0.001^*	−4.0–−1.4
Device size (mm)	24.7±8.4	26.7±6.3	0.004^*	−3.41–−0.66
Device/ASD diameter ratio	1.31±0.32	1.22±0.34	0.005^*	0.02–0.15
Procedural time (min)	55.8±15.7	57.8±23.7	0.3	−5.9–1.9
Fluoroscopy time (min)	10.2±6.1	13.9±9.0	<0.001^*	−5.2–−2.2

Values are expressed by mean ± SD.
