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.

:Pediatric tricuspid vavle endocarditis is an uncommon entity which is now becoming prevalent oweing to improved diagnostic methods and increase number of cardiac surgeries.Paediatric right sided infective endocarditis are mostly secondary to structural heart defects or indwelling venous catheters .We present a case of paeditric tricuspid valve endocarditis presenting with complete heart block,septic arthritis, pulmonary abcess with no structural heart defect diagnosted preoperatively.Intra-operatively a ventricular septal defect was diagnosed and managed .We present the difficult management of the case by medical and surgical intervention and management of secondary fungal infective endocarditis with repeated successful surgical intervention . We also emphasize on lack of established guidelines for management of right -sided infective endocarditis.

A method of producing complete heart block (CHB) in open-chest dogs is described. Having found previous methods unreliable in our hands or excessively complex for the acute open-chest setting, we constructed an electrocautery pinch-clamp device that functions in both locating and destroying the area of the atrial septum that contains the atrioventricular node and His bundle. Fifteen male mongrel dogs were anesthetized with alpha-chloralose, intubated, and ventilated (Harvard 607). Through a left thoracotomy at the fifth intercostal space, the two arms of the clamp are introduced into the left and right atria, respectively, via the atrial appendages. The correct site for electrocautery is located by gently squeezing the atrial septum between the arms of the clamp. Systematic testing of the region of the septum that lies, roughly, between the coronary sinus ostium and the anterior portion of the septal leaflet of the tricuspid valve will result in a rhythm disturbance when the correct site is squeezed. Sustained pressure will yield overt dissociation of the atrial and ventricular contractions. The electrocautery current is then activated for 10-15 s. Lead II of the electrocardiogram is monitored, and if CHB is not sustained after 5 min, the procedure is repeated. Once CHB is established, the clamp is removed and the atrial defects are ligated. By application of this method with no prior use of the technique, 12 of 15 attempts produced stable CHB lasting at least 3-4 h. Examination of the hearts of eight of the animals revealed no septal defects or damage to the tricuspid valve. We conclude that this method offers significant advantages for the production of CHB in acute studies in the dog.
