Mitral valve m-mode echo in complete heart block with atrial tachycardia

Background: The Maze procedure is the surgical treatment that can alleviate the three complications of atrial fibrillation- tachycardia, thrombo-embolism and hemodynamic compromise. We attempted ablation of atrial fibrillation with monopolar eletrocautery.Our objective was to evaluate the results of surgical treatment of atrial fibrillation by ablation of the left atrial wallaround the pulmonary veins with conventional electrocautery during mitral valve replacement.Methods:This retrospective observational study was carried out in the Department of Cardiac Surgery, National Institute of cardiovascular diseases, Dhaka, Bangladesh,from January 2014 to February 2016. Ablation of AF with monopolar electrocautery was done during mitral valve replacement. Recurrence of atrial fibrillation, any new arrhythmia, complete heart block, bleeding and perforation was noted during the operation and in postoperative period. Patients were followed up upto three months after the surgery.Results: All the Patients were free from atrial fibrillation after the procedure. At discharge 100 %, after I month 96.2% and after 3 months 92.3 % patient were free from atrial fibrillation. No patients developed complete heart block requiring pace maker and there was no incidence of atrial perforation at the sites of ablation.Conclusion: The surgical treatment of the atrial fibrillation with elcetrocautery during mitral valve replacement is able to reverse this arrhythmia in a significant number of patients during short term follow-up without any complication.Cardiovasc. j. 2016; 9(1): 9-12

Prosthetic valve endocarditis after transcatheter aortic valve replacement (PVE after TAVR) is a feared complication most often observed during the early postprocedural period. We report a case of severe, multivalvular PVE after TAVR with complete heart block caused by an uncommon organism. A 78-year-old female with prior Streptococcus agalactiae mitral valve endocarditis treated with antibiotics presented one year later with severe, symptomatic aortic insufficiency. She subsequently underwent TAVR given high surgical risk. Six weeks post-TAVR, she presented with syncope, fever, and complete heart block. Transthoracic echocardiogram was not demonstrative of vegetation. Blood cultures were positive for Staphylococcus lugdunensis. Transesophageal echocardiogram (TEE) demonstrated vegetations of the aortic, mitral, and tricuspid valves and aorto-mitral continuity. While awaiting surgery, the patient developed cardiac arrest; she was resuscitated and taken to surgery emergently. The patient underwent TAVR explantation, bovine pericardial tissue aortic and porcine bioprosthetic mitral valve replacements, and tricuspid valve repair. Additionally, left main coronary artery endarterectomy was performed due to presence of infectious vegetative material. Staphylococcus lugdunensis is an unusual but virulent organism that may damage both native and prosthetic valves. Early surgery is recommended for PVE after TAVR, especially in cases with perivalvular disease causing conduction abnormalities. Learning Objectives. TAVR has revolutionized the management of severe aortic stenosis and has even been successfully utilized in select cases of aortic regurgitation. Unfortunately, there are a number of associated complications that can be difficult to diagnose, such as prosthetic valve endocarditis (PVE). We emphasize maintaining a high clinical suspicion for PVE after TAVR in patients presenting with conduction abnormalities and highlight the importance of early surgical management in cases complicated by heart block, abscesses, or destructive penetrating lesions.

Pleomorphic Rhabdomyosarcoma

Primary cardiac tumours are rare and difcult to diagnose because most are asymptomatic or have varied non-specic presentations. This report describes a 29-year-old man presenting with complete heart block, primary cardiac tumour in the left atrium, and severe mitral regurgitation. In view of the primary severe mitral regurgitation and complete heart block, mitral valve repair and pacemaker insertion were planned. Mitral valve repair was done with 29mm St Jude tailor annuloplasty ring, and the biopsy was taken from the nodules noted in the left atrium; temporary right ventricular epicardial pacemaker implantation and CABG with SVG to PDA graft were done to look for the recovery of complete heart block. Histopathological examination revealed pleomorphic rhabdomyosarcoma. The patient developed renal failure and liver failure during the postoperative period and expired after 10 days
