1/3. Lyme carditis: restitutio ad integrum documented by cardiac magnetic resonance imaging.lyme disease is a tickborne illness that could cause, weeks to months later, complications involving the joints, central nervous system, and cardiovascular system. We report a case of cardiac manifestation with transitory higher degree atrioventricular block and dysfunction of the left ventricle. Complete resolution without signs of myocardial scar is demonstrated by cardiac magnetic resonance imaging.- - - - - - - - - - ranking = 1keywords = carditis (Clic here for more details about this article) |
2/3. Persistent atrioventricular block in Lyme borreliosis.Cardiac manifestations are reported in 0.3%-4.0% of European patients with borrelia burgdorferi (B.b.) infection. Usually symptoms disappear within 6 weeks. We report a case with persistent impairment of atrioventricular (AV) conduction. diagnosis was confirmed by demonstration of IgM antibodies and increase of IgG antibody titers against B.b. in serum, by isolation of the spirochete from skin biopsy material and by the typical clinical combination of erythema migrans, Bannwarth syndrome (meningoradiculitis), and complete heart block. Despite immediate antibiotic therapy with ceftriaxone, first degree AV block and second degree block Wenckebach with atrial pacing at 100 beats/minute persisted for 2 years. We conclude, that Lyme carditis can cause long-standing or irreversible AV conduction defects despite adequate and early antimicrobial therapy.- - - - - - - - - - ranking = 0.25keywords = carditis (Clic here for more details about this article) |
3/3. Lyme carditis: a clinical presentation and long time follow-up.The acute disease and a follow-up carried out up to 7 years after definite Lyme carditis in 6 patients is described. At the time of diagnosis all 6 patients had 2-3 degrees AV block, 4 patients presented with syncopes, and 1 revealed episodes of non-sustained ventricular tachycardia. The diagnosis of Lyme carditis was confirmed by borrelia burgdorferi-specific IgM and IgG antibody determinations in consecutive serum samples. All patients were treated with antibiotics. At follow-up, a clinical examination, a 2D and M-mode echocardiogram, and an exercise test did not reveal sequelae to Lyme carditis.- - - - - - - - - - ranking = 1.75keywords = carditis (Clic here for more details about this article) |
