1/37. Lyme carditis: complete AV dissociation with episodic asystole presenting as syncope in the emergency department.We report a case of Lyme carditis in an otherwise-healthy young male who presented to the Emergency Department (ED) with syncope and a possible seizure. This patient, without documented history of lyme disease, acutely developed third-degree atrioventricular (AV) block with episodic asystole, which required placement of a transvenous pacemaker in the ED and resolved only after the patient had been placed on ceftriaxone. We discuss the significance of Lyme carditis and its increasing prevalence, and review the current literature. We also recommend appropriate screening modalities for patients with known lyme disease, or an atypical profile for cardiac abnormalities.- - - - - - - - - - ranking = 1keywords = carditis (Clic here for more details about this article) |
2/37. borrelia burgdorferi as a cause of Morgagni-adams-stokes syndrome. Long time follow-up study.According the literature atrio-ventricular blockade (AVB) is the most frequent and well-known symptom of Lyme carditis. Typical signs of complete AVB include fatigue, lethargy and syncope- Morgagni-adams-stokes syndrome (MAS). The authors present their results and experience with 5 patients selected from a long-term study (conducted between 1987 and 1998) comprising 58 patients who developed MAS. The authors tried to evaluate the changes especially in the cardiovascular system. They correlated the clinical state with ECG findings, as well as with the levels of the borrelia burgdorferi antibodies. The following results were obtained: 1) all patients had typical syncope, 2) the clinical course was not complicated (except one patient who developed ventricular fibrillation), 3) two patients had frequent symptomatic and asymptomatic arrhythmia including chest pain and episodic rest dyspnea, 4) subjective difficulties (usually palpitations) correlated with ECG findings (Lown 3a, 3b). The authors also looked for any relationship between clinical difficulties and levels of antibodies. The results obtained with an early permanent pacemaker were less favourable than those reported in the literature. Despite early treatment 2 patients had repeated palpitations and ECG correlates during the next years.- - - - - - - - - - ranking = 0.16666666666667keywords = carditis (Clic here for more details about this article) |
3/37. Possible relationship between degenerative cardiac valvular pathology and lyme disease.We report an unusual clinical presentation of Lyme carditis in a previously healthy 20-year-old black woman without any epidemiologic history of lyme disease, fulminant in nature, involving a heart valve necessitating emergent mitral valve replacement, and requiring further surgical intervention because of the development of pericardial effusion and tamponade. A dilated right ventricle with normal contractility and severe tricuspid regurgitation with increase in the right atrial size diagnosed later remains under close surveillance.- - - - - - - - - - ranking = 0.16666666666667keywords = carditis (Clic here for more details about this article) |
4/37. Borrelia infection as a cause of carditis (a long-term study).BACKGROUND: Although the frequency of Lyme carditis is not high, it is one of the most challenging conditions in terms of diagnosis. No long-term studies that would help expand our body of knowledge concerning the circumstances of its development and the natural course of this form of Lyme borreliosis (LB), the most widespread anthropozoonosis in Central europe, have been reported to date. AIM: The authors sought to describe and assess the consequences of a less common form of Lyme carditis (LC). An assessment of the following aspects was made: a) the forms, natural history and sequelae of the less common clinical appearances of LC, b) the role of antibiotic therapy with reference to the late manifestations of LB. methods: Three patients were selected from a group of 60 consecutive patients with demonstrated LC during a follow-up period from 1987 to 2000. Patient no. 1 was being followed for myocarditis with frequent ventricular extrasystoles, patient no. 2 for pericarditis, and patient no. 3 for dilated cardiomyopathy as a late manifestation of LB. In addition to routine examination at entry, the patients were subjected to a standard 12-lead ECG, continuous 24-hour Holter ECG monitoring, exercise testing (bicycle ergometry), investigations of antibodies using ELISA and Western blot, investigation of thyroid (T3, T4, TSH tests) and mineral levels. RESULTS: The study showed no significant correlation between the clinical course and levels of specific antibodies. It confirmed the concept that inadequate or no therapy with antibiotics in the initial stage of the disease has a significant effect on the development of late sequelae. CONCLUSION: Based on the long-term treatment of three patients with less common, yet clinically urgent findings, the authors conclude that even a relatively serious clinical course is associated with no major limitations for affected individuals after an interval of several years.- - - - - - - - - - ranking = 1.3333846750711keywords = carditis, myocarditis (Clic here for more details about this article) |
5/37. Complete heart block due to lyme carditis.Lyme carditis is becoming a more frequent complication of lyme disease, primarily due to the increasing incidence of this disease in the united states. Cardiovascular manifestations of lyme disease often occur within 21 days of exposure and include fluctuating degrees of atrioventricular (AV) block, acute myopericarditis or mild left ventricular dysfunction and rarely cardiomegaly or fatal pericarditis. AV block can vary from first-, second-, third-degree heart block, to junctional rhythm and asystolic pauses. patients with suspected or known lyme disease presenting with cardiac symptoms, or patients in an endemic area presenting with cardiac symptoms with no other cardiac risk factors should have a screening electrocardiogram along with Lyme titers. We present a case of third-degree AV block due to Lyme carditis, illustrating one of the cardiac complications of lyme disease. This disease is usually self-limiting when treated appropriately with antibiotics, and does not require permanent cardiac pacing.- - - - - - - - - - ranking = 1.3333333333333keywords = carditis (Clic here for more details about this article) |
6/37. 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 = 0.66666666666667keywords = carditis (Clic here for more details about this article) |
7/37. Transient prolonged corrected QT interval in lyme disease.lyme disease, caused by the spirochete borrelia burgdorferi, has known cardiovascular effects typically manifesting in varying degrees of atrioventricular block. Three patients presented with QT interval prolongation associated with lyme disease, a previously unreported manifestation of Lyme carditis. Implications and a proposed clinical management approach are discussed.- - - - - - - - - - ranking = 0.16666666666667keywords = carditis (Clic here for more details about this article) |
8/37. Lyme borreliosis infection as a cause of dilated cardiomyopathy.The relatively low percent of patients affected with the cardiac form of Lyme borreliosis is difficult to diagnose, especially if the disease manifests itself in ways other than atrio-ventricular blockade. The advanced stage of Lyme carditis manifesting as dilated cardiomyopathy is a special case of this affliction. The authors of this report present clinical experience with an attempt to support the working hypothesis about involvement of Lyme borreliosis infection in the development of dilated cardiomyopathy. The patients were clinically examined thoroughly with special attention to the cardiovascular system. In addition to the basic clinical methods, the following procedures have been employed: dynamic Holter's electrocardiography, exercise ECG test, coronarography, and myocardial biopsy. From laboratory methods pertaining to the detection of Borrelia, ELISA method, Western blot, PCR, electron microscopy and histopathological analysis were used. In all three cases, clinical and laboratory findings provided the evidence of the borreliosis infection involvement in the development of dilated cardiomyopathy.- - - - - - - - - - ranking = 0.16666666666667keywords = carditis (Clic here for more details about this article) |
9/37. Lyme carditis: complete atrioventricular dissociation with need for temporary pacing.Lyme borreliosis is a tick-borne disease. Cardiac manifestations of the disease are extremely rare. We report a case of Lyme carditis in an otherwise healthy male, who presented to the Accident & Emergency Department with chest pain, dizziness and generally symptoms indicating ischaemic heart disease. This patient, without documented history of lyme disease, acutely developed third-degree atrioventricular block, which required placement of a transvenous pacemaker and resolved when the patient was administered doxycycline.- - - - - - - - - - ranking = 0.83333333333333keywords = carditis (Clic here for more details about this article) |
10/37. Intra-hisian 2:1 atrioventricular block secondary to lyme disease.We describe a case of Lyme carditis with intra-hisian 2:1 atrioventricular (AV) block documented by electrophysiological study. To our knowledge, only two cases of AV block at the level of the His bundle has been described in the literature. Sinus rhythm was restored after 4 days of i.v. ceftriaxone.- - - - - - - - - - ranking = 0.16666666666667keywords = carditis (Clic here for more details about this article) |
