Why the study?
Myocarditis with conduction system abnormalities or congestive heart failure may complicate postnatal rubella infection, but detailed cardiac involvement is not well characterized.
Rubella may trigger AV block or myocarditis in children; extends viral arrhythmia links but leaves open any screening or practice changes.
Two cases of rubella myocarditis are reported: a 6-year-old boy who developed a complete, distal to His, atrioventricular block, during the third day of illness; and a 12-year-old boy who developed myocarditis with congestive heart failure 20 days following rubella infection. Although permanent pacing was required in the first patient, six years later he showed a normal growth and maintained normal activity. The second patient has deteriorated markedly and 6 months after the initial illness he had severe heart failure. It should be noted that myocarditis with abnormalities of the conduction system or congestive heart failure may be a complication to postnatal rubella.
