Very late occurrence of complete heart block without preexisting atrioventricular conduction abnormalities: A rare complication after transaortic valvular replacement

Ventricular tachyarrhythmias are common in hypertrophic cardiomyopathy that may lead to syncope and sudden death. Bradyarrhythmia such as atrioventricular conduction disturbance, a relatively rare complication associated with hypertrophic cardiomyopathy, may also cause syncope and sudden death in hypertrophic cardiomyopathy. We report a 28-year old man who was diagnosed as a case of hypertrophic cardiomyopathy presented with syncope and complete heart block. Subsequently, a permanent pacemaker was implanted to the patient.

Abstract This case illustrates acute myocarditis with complete heart block in a 13-year-old teenager as a rare complication of acute dengue illness. He required urgent temporary pacing with inotropic support and antifailure medications. Complete heart block in dengue myocarditis is an acute but reversible condition. A similar presentation in a dengue-endemic country or with a history of travelling to tropical countries warrants a suspicion of dengue infection.

Review Of The Literature

Thyrotoxicosis complicated by advance degree atrioventricular block, a rare complication of a common disease. The term apathetic thyrotoxicosis, where palpitations and cardiac involvement are the sole manifestations of disease, is well known. Thyroxin's ability to sensitize the catecholamine receptors causing tachyarrhythmias is well addressed. However, as an aetiology for advanced heart block, thyrotoxicosis is ranked as one of the rarest.

Valve Pathology

Abstract Background Right-sided tricuspid valve (TV) endocarditis can be difficult to identify and may be under-recognized in the absence of traditional risk factors. While generally identified with aortic valve pathology, infective endocarditis that extends beyond the leaflets of the TV have been reported to cause conduction disease. Case summary We present the case of a 63-year-old patient who presented with haemodynamically unstable complete heart block requiring temporary venous pacemaker support. Despite the absence of traditional risk factors or significant valvular disease on transthoracic echocardiogram, she was found to be persistently bacteraemic and subsequent transoesophageal echocardiogram identified large vegetation on the septal leaflet of the TV. Conduction disease was noted to reverse with antibiotic therapy and resolution of bacteraemia. Discussion Although rare, right-sided endocarditis involving the triangle of Koch may present with conduction disease due to local inflammation and mechanical compression. Conduction disease associated with right-sided disease appears to be readily reversible with medical therapy and temporary device support may be appropriate in the acute setting.

A case report of a 4-year-old girl with tetralogy of Fallot who developed A-V dissociation during cardiac catheterization is presented. His bundle electrograms performed six days later localized the block proximal to the recorded His potential. The child has been followed for six months and is well with alternating Wenckebach and first degree heart block.
