Table 3:

Comparison of Strain Ratios (Post/Pre-exercise) From the Left Ventricular Inferior and Anterior Walls Between Unoperated and Operated AAORCA Patients Versus Controls.

	Study Groups			P values^a
	Unoperated AAORCA	Operated AAORCA	Controls	Unoperated vs Control	Operated vs Control
Mean TPScR (inferior)	0.96 (0.41)	0.84 (0.28)	0.76 (0.18)	0.03	0.23
Mean TPScR (anterior)	0.98 (0.31)	0.75 (0.24)	0.84 (0.16)	0.08	0.85
Mean PSSR (inferior)	0.97 (0.41)	1.30 (0.69)	1.23 (1.18)	0.25	0.57
Mean PSSR (anterior)	1.02 (0.34)	1.16 (0.54)	0.86 (0.39)	0.85	0.93
Mean SDIR (inferior)	1.09 (0.59)	1.07 (0.90)	0.84 (0.36)	0.92	0.78
Mean SDIR (anterior)	0.86 (0.41)	1.58 (1.60)	1.08 (0.51)	0.14	0.84

Abbreviations: AAORCA, anomalous aortic origin of the right coronary artery; PSSR, ratio of post- over pre exercise peak systolic strain; SDIR, ratio of post- over pre-exercise strain diastolic index; TPScR, ratio of post over pre-exercise time to peak systolic strain corrected for heart rate.

Based on one-sided Student’s t-test.
