Overview
An echocardiogram may be helpful in the diagnosis of Kawasaki disease. Findings on an echocardiogram suggestive of Kawasaki disease include coronary artery dilatation, stenosis or aneurysms, left ventricular dysfunction, pericardial effusion, and mitral regurgitation.
Echocardiography/Ultrasound
Echocardiography
An ECG may be helpful in the diagnosis of Kawasaki disease. Findings on an ECG suggestive of Kawasaki disease include:
- Coronary artery dilatation
- Left ventricular dysfunction
- Pericardial effusion
- Mitral regurgitation
Echocardiographic Views of Coronary Arteries in Patients With KD
| Adapted from the AHA Scientific Statement on the diagnosis, treatment, and long term management of Kawasaki disease[1] | |
| LMCA | Precordial short axis at level of aortic valve; precordial long axis of left ventricle (superior tangential); subcostal ventricular long axis |
|---|---|
| LAD coronary artery | Precordial short axis at level of aortic valve; precordial superior tangential long axis of left ventricle; precordial short axis of left ventricle |
| Left circumflex branch | Precordial short axis at level of aortic valve; apical 4-chamber |
| RCA, proximal segment | Precordial short axis at level of aortic valve; precordial long axis (inferior tangential) of left ventricle; subcostal coronal projection of right ventricular outflow tract; subcostal short axis at level of atrioventricular groove |
| RCA, middle segment | Precordial long axis of left ventricle (inferior tangential); apical 4-chamber; subcostal left ventricular long axis; subcostal short axis at level of atrioventricular groove; RCA proximal (#1) and mid (#2) are observed in the atrioventricular groove from the third intercostal space at the left and right sternal border |
| RCA, distal segment | Apical 4-chamber (inferior); subcostal atrial long axis (inferior) |
| Posterior descending coronary artery | Apical 4-chamber (inferior); subcostal atrial long axis (inferior); precordial long axis (inferior tangential) imaging; posterior interventricular groove |
| KD indicates Kawasaki disease; LAD, left anterior descending; LMCA, left main coronary artery; and RCA, right coronary artery | |
AHA Recommendations for Cardiovascular Assessment for Diagnosis and Monitoring During the Acute Illness
The AHA Recommendations for Cardiovascular Assessment for Diagnosis and Monitoring During the Acute Illness are:[1]
| Class I |
| "1. Echocardiography should be performed when the diagnosis of Kawasaki Disease is considered, but unavailability or technical limitations should not delay treatment (Class I; Level of Evidence B). |
| "2. Coronary arteries should be imaged, and quantitative assessment of luminal dimensions, normalized as Z scores adjusted for body surface, should be performed (Class I; Level of Evidence B). |
| "3. For uncomplicated patients, echocardiography should be repeated both within 1 to 2 weeks and 4 to 6 weeks after treatment (Class I; Level of Evidence B). |
| "4. For patients with important and evolving coronary artery abnormalities (Z score >2.5) detected during the acute illness, more frequent echocardiography (at least twice per
week) should be performed until luminal dimensions have stopped progressing to determine the risk for and presence of thrombosis (Class I; Level of Evidence B). |
| Class IIa |
| "1. To detect coronary artery thrombosis, it may be reasonable to perform echocardiography for patients with expanding large or giant aneurysms twice per week while dimensions are expanding rapidly and at least once weekly in the first 45 days of illness, and then monthly until the third month after illness onset, because the failure to escalate thrombo-prophylaxis in time with the rapid expansion of aneurysms is a primary cause of morbidity and mortality (Class IIa; Level of Evidence C). |
Ultrasound
Ultrasound may show hydrops (enlargement) of the gallbladder.
