Complete heart block from mycoplasma pneumoniae infection

Abstract

Complete heart block (CHB) in infants and children is usually congenital. Nonsurgical acquired CHB is rare. Occasionally, transient acquired CHB is seen in association with viral myocarditis. We describe here an unusual case of transient CHB in a 12-year-old boy with endomyocardial biopsy-proven myocarditis and evidence of Mycoplasma pneumoniae infection.

<i>Mycoplasma</i>-Associated Carditis

“…Exanthemas and gastrointestinal symptoms are quite common [1], whereas Mycoplasma -associated carditis (myo- or pericarditis) is an uncommon complication, occurring in 1–5% of the patients. Since the review by Pönkä [2] published in 1979, we have found 19 additional cases of Mycoplasma- associated carditis in the medical literature [3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16]. During this period, considerable progress regarding diagnosis and treatment has been achieved.…”

Extraskeletal calcifications in a dialysis-dependent teenager: A novel cause of acquired pediatric complete heart block

“…Acquired complete heart block in nonsurgical pediatric patients is rare, most commonly caused by maternal autoimmune antibodies or myocarditis. 2 This is, to our knowledge, the first reported case of calcium deposition secondary to renal disease causing complete AV block in a child with previously normal cardiac conduction and function.…”

A Case of Fatal Myocarditis Associated with Mycoplasma pneumoniae Pneumonia

“…Ponka 10) reported that the mean age was 32 years among the patients with M. pneumoniae associated carditis. Carditis associated with M. pneumoniae may be caused by the following 1,9,11) . Direct in- .…”
