Aortic annular enlargement techniques using an original patch for prosthetic valve endocarditis.

ABSTRACT: BACKGROUND:Prosthetic valve endocarditis (PVE) is a serious complication, and it is difficult to treat marked adhesion and infectious tissue. CASE PRESENTATION:There were four patients with aortic PVE, whose ages ranged from 59 to 80?years. In all patients, transoesophageal echocardiography revealed periannular abscess formation. We applied aortic annular enlargement techniques using a composite three-layer patch to repair the defects after radical debridement of the abscesses, and then replaced the prosthetic valves on the reconstructed annuli. All patients received antibiotics after surgery and recovered well without recurrence. CONCLUSIONS:The aortic annular enlargement techniques provided a good field of vision at the complicated annulus, and our original patch was useful for repairing the aortic annulus and its surrounding apparatus.

<i>Cellulosimicrobium cellulans</i> aortic prosthetic valve endocarditis.

Project description:IntroductionInvasive infections due to Cellulosimicrobium spp. (a Gram-positive coryneform) are extremely rare. Only a few cases of bloodstream infections and endocarditis have been described, as bacteraemia due to coryneforms is usually discarded as blood culture contamination.Case presentationA 66-year-old female, with a history of aortic valve replacement, presented with fever, left leg purpura and acute kidney injury. Multiple repeated blood cultures were positive for Cellulosimicrobium cellulans , and targeted therapy was started. At first, endocarditis was excluded by echocardiograms, and the acute nephritis was interpreted as an atypical presentation of Henoch-Shönlein purpura. High-dose prednisone was started, and after 10 weeks the patient presented again with fever, mental confusion and acute left arm ischaemia. A subsequent echocardiogram and radiolabelled leukocyte scintigraphic evaluation revealed aortic prosthetic valve endocarditis with periprosthetic abscess and arterial brachial thrombosis. The patient deceased, and the autoptic examination confirmed an aortic valve periprosthetic abscess and revealed multiple arterial thromboses and septic embolisms in the kidneys, brain, spleen and myocardium.ConclusionIsolation of coryneform bacteria on blood culture should not always be discarded as blood culture contamination. In the case of endocarditis due to Cellulosimicrobium spp., the removal of any prosthetic material, along with prolonged in vitro active antimicrobial therapy, should be pursued in order to reduce persistence or relapses of infection.

Successful surgical aortic valve replacement for prosthetic valve infective endocarditis following transcatheter aortic valve implantation.

Project description:An 80-year-old male underwent a transcatheter aortic valve implantation (TAVI) for severe senile aortic stenosis. Six weeks after the surgery, he was readmitted to our institution because of a high-grade fever. Transesophageal echocardiography revealed thickening of all three leaflets of the aortic prosthesis and mobile mass on the leaflet, and Streptococcus sanguis was identified from his blood culture. Therefore, he was diagnosed with prosthetic valve endocarditis (PVE) and received intensive intravenous antibiotic therapy. Because he did not respond to the pharmacological therapy, surgical aortic valve replacement (AVR) was indicated although it was considered a relatively high-risk procedure. Herein, we report on the successful surgical AVR in this patient using a pericardial valve after removal of the infected prosthetic valve, and discuss some issues related to this rare complication after TAVI. <Learning objective: Transcatheter aortic valve implantation (TAVI) is a highly effective procedure for patients with symptomatic severe aortic stenosis who are at high risk or deemed inoperable. Because it only requires limited surgical invasiveness, the risk of prosthetic valve endocarditis (PVE) after TAVI is thought to be low. However, PVE can occur even early after TAVI. We present our recent such case and discuss some issues related to this rare complication.>.

Prosthetic Valve Endocarditis After Aortic Valve Replacement With Bovine Versus Porcine Bioprostheses.

Project description:BackgroundWhether a bovine or porcine aortic valve bioprosthesis carries a higher risk of endocarditis after aortic valve replacement is unknown. The aim of this study was to compare the risk of prosthetic endocarditis in patients undergoing aortic valve replacement with a bovine versus porcine bioprosthesis.Methods and resultsThis nationwide, population-based cohort study included all patients who underwent surgical aortic valve replacement with a bovine or porcine bioprosthesis in Sweden from 1997 to 2018. Regression standardization was used to account for intergroup differences. The primary outcome was prosthetic valve endocarditis, and the secondary outcomes were all-cause mortality and early prosthetic valve endocarditis. During a maximum follow-up time of 22 years, we included 21 022 patients, 16 603 with a bovine valve prosthesis and 4419 with a porcine valve prosthesis. The mean age was 73 years, and 61% of the patients were men. In total, 910 patients were hospitalized for infective endocarditis: 690 (4.2%) in the bovine group and 220 (5.0%) in the porcine group. The adjusted cumulative incidence of prosthetic valve endocarditis at 15 years was 9.5% (95% CI, 6.2%-14.4%) in the bovine group and 2.8% (95% CI, 1.4%-5.6%) in the porcine group. The absolute risk difference between the groups at 15 years was 6.7% (95% CI, 0.8%-12.5%).ConclusionsThe risk of endocarditis was higher in patients who received a bovine compared with a porcine valve prosthesis after surgical aortic valve replacement. This association should be considered in patients undergoing both surgical and transcatheter aortic valve replacement.

Direct Implant of a Transcatheter Aortic Valve Prosthesis for Prosthetic Mitral Valve Endocarditis.

Project description:We describe the case of a 64-year-old woman presenting with severe prosthetic mitral valve endocarditis 1 year after coronary artery bypass grafting and double valve replacement. Echocardiogram revealed high-pressure gradients through the bioprosthetic MV with a bulky vegetation. As the patient had presented operative difficulties due to severe mitral annular calcification, was in renal failure, and in the absence of any perivalvular involvement, an open-heart surgical catheter-based valve implantation was successfully performed after removal of the infected leaflets, leaving the stent frame and sewing cuff behind. Albeit controversial, this case represents an alternative approach for select high-risk reoperative mitral cases with mitral annular calcification.

Successful redo aortic valve replacement using Perceval valve in a patient with prosthetic valve endocarditis complicated by acute cerebral infarction.

Project description:Introductionand importance: For treatment of prosthetic valve endocarditis (PVE), redo-aortic valve replacement (AVR) is usually required. However, the recurrence of PVE continues to be a serious problem that needs a solution.Case presentationAn 83-year-old woman who had undergone AVR for aortic infective endocarditis 12 years ago was diagnosed with PVE complicated with acute cerebral infarction. Urgent redo-AVR was performed. After complete removal of the prosthesis, Perceval S valve was implanted successfully. There were no postoperative neurological deteriorations, and the echocardiogram showed no recurrence of PVE.Clinical discussionTheoretically, the fewer prostheses left in the heart, the lower the risk of PVE recurrence.ConclusionIn patients with PVE, redo-AVR using the Perceval valve may be a suitable option since Perceval reduces the prosthesis in the heart compared with conventional redo-AVR.

Prosthetic valve endocarditis secondary to <i>Corynebacterium</i> following transcatheter aortic valve implantation: a case report.

Project description:BackgroundTranscatheter aortic valve implantation (TAVI) has emerged as an alternative for the treatment of severe symptomatic aortic stenosis for patients at high risk for open surgery. Although experience with TAVI is increasing, few cases of post-TAVI endocarditis are reported.Case summaryWe present a case of an 87-year-old female patient who presented with fever, unresponsive to empiric antibiotics 3 months after a TAVI procedure for severe aortic valve stenosis. After some delay due to three hospitalizations in primary care hospitals, she was transferred to our general intensive care unit where the diagnosis of endocarditis due to Corynebacterium was made. The patient was transferred abroad to a specialized surgical centre of excellence and underwent aortic root and valve replacement with a homograft. After several post-operative complications the patient's condition improved and is presently satisfactory.DiscussionKeeping a high index of suspicion when evaluating patients might lead to a favourable outcome if appropriate and early intervention was implemented. Adherence to policies which address infection control and aseptic techniques when performing TAVI might lead to fewer cases of post-TAVI endocarditis.

Prosthetic mitral valve Aspergillus fumigatus endocarditis.

Project description:Aspergillus endocarditis is a fatal source of valvular infection with a near 100 % mortality rate if pharmacotherapy and valve-replacement surgery are not initiated swiftly after diagnosis. Complicating its diagnosis is the low yield for growth on standard blood culture and time requirements for molecular diagnostic tools to return a result. Aspergillus endocarditis of the mitral valve presents as valvular vegetations that reduce the caliber of the mitral valve and can cause syncope as in the case of mitral stenosis with subsequent valve failure, left atrial enlargement, and prospective cardiovascular failure. Reports of the management of Aspergillus endocarditis after serial mitral valve replacement are not prominent in the literature. We report the case of a 41-year-old female with previous mitral valve prosthesis who received a second prosthetic mitral valve after a syncopal episode. Vegetations resembling thrombi were noted on transesophageal echocardiogram, diagnosed as Aspergillus fumigatus endocarditis, and successfully treated with antifungal therapy in conjunction with removal of her dysfunctional prosthesis.
