Unexpectedly high incidence of Kawasaki Disease in a Canadian Atlantic Province- an 11-year retrospective descriptive study

Table 2 Cardiac complications documented in the Kawasaki Disease study population

			Number of patients (%)
Pericardial effusion^a
Small			16 (7.3)
Valvular lesion^b
Mitral regurgitation (Mild to Moderate)			1 (0.5)
Left ventricular dysfunction based on M mode
Mild dysfunction			5 (2.3)
Coronary artery abnormalities^d	Coronary artery ectasia		23 (10.5)
	Coronary artery aneurysm	13 (6)	Small^c	7 (3.2)
			Moderate^c	3 (1.4)
			Large/Giant^c	3 (1.4)

^a Only small or larger degrees of pericardial effusion are reported
^b Only valvular lesions with regurgitation rated as greater than mild regurgitation are reported
^c All of those patients had calculated coronary artery z scores
^d Coronary artery aneurysm sizes were defined according to the AHA Z-score criteria; small aneurysm: ≥ 2.5 to < 5, medium aneurysm: ≥ 5 to < 10, large/Giant aneurysm: ≥ 10
