Doppler detection of tricuspid regurgitation following Kawasaki disease
Abstract:
Between June 1984 and April 1985, five patients (4.2%) had tricuspid regurgitation detected on pulsed Doppler echocardiography among 119 patients with Kawasaki disease. The grade of tricuspid regurgitation was moderate in three and mild in two patients; conventional cardiac examinations revealed no evidence of this complication. All patients had associated coronary artery aneurysms except one, but no patients developed subsequent myocardial infarction. The occurrence of tricuspid regurgitation following Kawasaki disease has been considered to be causally related to the carditis, a frequent complication during the acute febrile period of the illness. The present data indicate that tricuspid regurgitation is an additional cardiovascular complication of Kawasaki disease and that Doppler echocardiography is useful in detecting this disorder.
Insights
Tricuspid regurgitation is a cardiovascular complication in Kawasaki disease. Doppler echocardiography effectively detects this condition, often missed by conventional cardiac exams in affected children.
Area of Science:
- Pediatric Cardiology
- Echocardiography
- Rheumatology
Background:
- Kawasaki disease is a significant cause of acquired heart disease in children.
- Carditis is a common complication during the acute phase of Kawasaki disease.
- Conventional cardiac examinations may not detect all cardiovascular complications.
Purpose of the Study:
- To investigate the prevalence of tricuspid regurgitation in patients with Kawasaki disease.
- To evaluate the utility of Doppler echocardiography in detecting tricuspid regurgitation in this population.
- To identify tricuspid regurgitation as a potential cardiovascular complication of Kawasaki disease.
Main Methods:
- Pulsed Doppler echocardiography was performed on 119 patients diagnosed with Kawasaki disease.
- Cardiac examinations were conducted for comparison.
- Patient data including coronary artery aneurysm status and myocardial infarction were reviewed.
Main Results:
- Tricuspid regurgitation was detected in 5 patients (4.2%) using Doppler echocardiography.
- The regurgitation was graded as moderate in three and mild in two patients.
- Conventional cardiac exams did not reveal tricuspid regurgitation in any of these patients.
- Four patients had associated coronary artery aneurysms; none developed myocardial infarction.
Conclusions:
- Tricuspid regurgitation is an additional cardiovascular complication associated with Kawasaki disease.
- Doppler echocardiography is a valuable tool for detecting tricuspid regurgitation in Kawasaki disease patients.
- Early detection of tricuspid regurgitation may inform management strategies for Kawasaki disease complications.
