Tricuspid Valve Replacement (tricuspid + valve_replacement)
Selected AbstractsNarrow QRS Complex Tachycardia Following Tricuspid Valve ReplacementJOURNAL OF CARDIOVASCULAR ELECTROPHYSIOLOGY, Issue 8 2004VOLKHARD GOEBER M.D. [source] Ablation of Atrial Flutter in a Patient with a Tricuspid Valve Replacement after EndocarditisPACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 9 2009PETER NORDBECK M.D. Myocardial scars from heart surgery are a source of tachycardia, eventually causing late morbidity and sudden death. In general, catheter ablation has been shown to be an effective therapy for various rhythm disorders, but it has been rarely described after atrioventricular valve replacement. We report on a 45-year-old man who developed atrial flutter after implantation of a tricuspid valve bioprosthesis. An electrophysiological investigation revealed typical type-I counterclockwise atrial flutter that was successfully terminated by catheter ablation. A sinus rhythm was restored and remained stable during the course of treatment; the valvular function was not diminished. It is demonstrated that safe mapping and ablation of typical atrial flutter is possible after a tricuspid valve replacement. [source] Utilization of the Edge-to-Edge Valve Plasty Technique to Correct Severe Tricuspid Regurgitation in Patients with Congenital Heart DiseaseJOURNAL OF CARDIAC SURGERY, Issue 6 2009Yong-chao Cui Significant morbidity and mortality are related to tricuspid valve replacement. Tricuspid valve plasty is still a preferred choice. This report deals with our surgical experience in using the edge-to-edge valve plasty technique to correct severe tricuspid regurgitation in patients with congenital heart disease. Methods: From December 2002 to August 2007, severe tricuspid regurgitation was corrected with a flexible band annuloplasty and edge-to-edge valve plasty technique in nine patients with congenital heart disease. The age ranged from 7 to 62 years (average 24.4 years). Congenital cardiac anomalies included atrioventricular canal in five cases, secundum atrial septal defect in three cases, and cor triatriatum in one case. Results: No hospital death or postoperative morbidity occurred. No or trivial tricuspid regurgitation was present in six cases and mild tricuspid regurgitation in three cases at discharge. The follow-up ranged from 12 months to 70 months (average 39.3 months). No tricuspid stenosis was found. No to mild tricuspid regurgitation was present in eight cases, and moderate tricuspid regurgitation in one case at the latest follow-up. Conclusions: Edge-to-edge valve plasty is an easy, effective, and acceptable additional procedure to correct severe tricuspid regurgitation in patients with congenital heart disease. [source] A Technique of Snaring Method for Fitting a Prosthetic Valve into the AnnulusJOURNAL OF CARDIAC SURGERY, Issue 1 2005Shigeo Nagasaka M.D. We modified the previously reported method and designed a simpler tying technique. Patients: We performed 11 aortic (AVR: including four cases for calcified aortic stenosis (AS) with a small annulus and one cases for infective endocarditis with intramuscular abscess cavity), eight mitral valve replacements (MVR), and one tricuspid valve replacement (TVR: for corrected transposition of the great arteries). Techniques and Results: A PV was implanted using 2-0 polyester mattress sutures with a pledget. Each of the two tourniquets held a suture at the bottom of the annulus and at the opposite position to fit a PV. The sutures between each snare were tied down from the bottom to the top. In MVR, after seating of a PV with two tourniquets, we could make sure that no native tissue of any preserved mitral apparatus disturbed PV leaflet motion. In calcific AS, a PV had a good fitting into the annulus because of tourniquets applied to unseated part during tying sutures. In AVR for infective endocarditis, mattress sutures supported by a Teflon pledget were placed to close the abscess cavity. After snaring on one of these sutures, we tied down the sutures, ensuring that they did not cut through the friable tissues. In TVR, we found that native leaflets interfered with PV motion after seating down the prosthesis and those leaflets were resected before tying down the sutures. Postoperative transesophageal echocardiography showed no paravalvular leakage in any patients and excellent PV functions. [source] Transvenous Cardioverter-Defibrillator Implantation in a Patient with Tricuspid Mechanical ProsthesisJOURNAL OF CARDIOVASCULAR ELECTROPHYSIOLOGY, Issue 3 2007MAURO BIFFI M.D. Background. A 64-year-old woman was referred to our center because of poorly tolerated ventricular tachycardia (VT) at 210 bpm due to an old myocardial infarction. The patient had been operated on at age of 20 for mitral valve commissurolysis, at age of 49 for ductal carcinoma, at age of 56 for mitral valve replacement, and at age of 61 for tricuspid valve replacement. Left ventricular EF was 31%. The patient was in permanent atrial fibrillation (AF) since the age of 53. She had undergone three cardiac surgery procedures, ending with two prosthetic mechanical valves. The cardiac surgery team advised against an epicardial ICD implantation. Results. We achieved a fully transvenous implant, with a screw-in defibrillation coil in the low right atrium and a bipolar pacing/sensing lead in a posterolateral branch of the coronary sinus. Pacing/sensing parameters were reliable, and effective defibrillation occurred at 20 J by a stepdown protocol. During 16-month follow-up, three VT episodes at 210 bpm were terminated by antitachycardia pacing (ATP) therapy. Left ventricular pacing/sensing was stable at long term. Conclusion. Thanks to technologic improvements, transvenous ICD implantation is feasible and safe in patients with a tricuspid mechanical prosthesis. [source] Lungenembolie durch Aspergillose (sog.

Schwesinger cardiac tumour; aspergillosis; pulmonary embolism Zusammenfassung Ein 71jähriger Mann entwickelte bei einem Zustand nach Schrittmacherimplantation bei Arrhythmie und Mehrfachrevisionen wegen Schrittmachertascheninfektionen einen Tumor im rechten Ventrikel. Notfallmäßiger Trikuspidalklappenersatz durch ein Carpentier Edwards Xenograft. Die Schrittmachersonden und das Endokard waren durch Aspergillus in Gestalt eines Aspergilloms infiziert. Durch dieses Material kam es zu einer Lungenembolie, was relativ selten ist. Summary A 71-year-old man developed a cardiac tumour in the right ventricle and a pulmonary embolism caused by aspergillosis after implantation of a pacemaker because of arrhythmia. Repeated revisions during pocket infections. Emergency operation and tricuspid valve replacement with a Carpentier Edwards xenograft. The pacing electrodes and the endocardium were infected by Aspergillus in form of an aspergilloma. This case is an example of the rare condition of a pulmonary embolism with pure fungal material.
