Project description:BackgroundTranscatheter valve-in-valve replacement (TMViVR) is an alternative option for patients with bioprosthetic valve failure (BVF) who are at high surgical risk. Although infective endocarditis (IE) after transcatheter mitral valve-in-valve replacement is unusual, it is associated with significantly high mortality.Case presentationAn 81-year-old male patient was admitted with intermittent thoracic tightness, chest pain persisting for 3 years, and shortness of breath with nausea for 1 week. Two months prior, he received transcatheter mitral valve-in-valve replacement for recurrent heart failure and severe prosthetic mitral regurgitation. He developed a fever in the early postoperative period after TMViVR, with Staphylococcus lugdunensis bacteremia detected. He was discharged from the hospital after the blood culture turned negative following antibiotic treatment. During this hospitalization, prosthetic valve endocarditis was confirmed, resulting in severe prosthetic mitral stenosis and severe pulmonary hypertension. Blood cultures identified Staphylococcus lugdunensis again. Despite anti-infective therapy, the patient succumbed to complications from his complex medical history and comorbidities.ConclusionsWhile transcatheter valve implantation provides an alternative option for dealing with valvular disease, prosthetic valve endocarditis (PVE) as an unusual but catastrophic complication with poor prognosis should be taken seriously. Early detection through echocardiography, especially in high-risk patients presenting with suspicious symptoms, is crucial for timely intervention. Additionally, an appropriate perioperative antibiotic regimen is essential to prevent infection and improve prognosis.

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.>.

Project description:BackgroundSurgical aortic valve replacement remains the gold standard of treatment in patients with active infective endocarditis. Such procedures tend to carry a significantly higher operative risk when compared to the conventional aortic valve replacement for a non-infective aortic valve disease. Sutureless aortic valve replacement (SU-AVR) has been introduced into cardiac surgery to allow for a simpler implementation of minimally invasive procedures. Although SU-AVR in several extended indications has proven to be successful, the data on the implementation of SU-AVR in patients with infective aortic valve endocarditis remain scarce. The aim of the study was to examine the feasibility of SU-AVR in high-risk patients with active infective aortic valve endocarditis.MethodsBetween December 2019 and March 2022, a total of 151 consecutive patients underwent a SU-AVR for various indications at our institution. Of those, in 13 consecutive high-risk patients SU-AVR was indicated because of infective aortic valve endocarditis. In all cases Perceval S aortic valve prosthesis (Corcym, Saluggia, Italy) was used and the implantation has been performed with Snugger-method.ResultsThe mean age of the patients at operation was 74.05±11.6 years. Eight of the patients suffered from prosthesis endocarditis while the other five patients presented with the endocarditis of the native aortic valve. All patients suffered from multiple comorbidities, as reflected by a mean logistic EuroSCORE of 47.9%±23.1% and EuroSCORE II of 28.7%±22.0%. In 8 patients (61.5%) a concomitant procedure was necessary. Also 8 patients (61.5%) underwent a redo procedure. Bypass- and cross-clamp (CC) times were 89.8±33.6 and 59.1±27.8 minutes, respectively. We observed no paravalvular leakage and no cases of left-ventricular outflow tract obstruction. Postoperative mean gradients after SU-AVR implantation were 8.1±4.8 mmHg.ConclusionsSU-AVR in patients presenting with active infective endocarditis is a safe and feasible surgical alternative to the conventional operation. Clearly, this operative approach should be considered particularly for high-risk patients in whom successful operative outcomes are determined by a reduction in bypass and CC time. SU-AVR provides excellent hemodynamic performance with a low risk of paravalvular leakage and low transvalvular gradients, whilst simplifying the surgical procedure.

Project description:ObjectivesThis study aims to explore the potential efficacy of the Freestyle Medtronic bioroot in the treatment of aortic endocarditis, based on our single-centre experience.MethodsIn this retrospective study conducted between 2015 and 2023, adult patients who underwent aortic root replacement with coronary arteries reimplantation using the modified Bentall technique with a Medtronic Freestyle bioroot in our centre for infective endocarditis were included.ResultsThirty patients, with five deaths, no cases of relapse and two cases of reinfection, were included, and prosthetic valve endocarditis represented 73.3% of cases. The median age was 66 years (IQR 14.5 years), and 24/30 (80%) were male. Median EuroSCORE II was 12.2% (IQR 13.9%). The most commonly identified pathogen was Staphylococcus aureus (eight cases; 23.3%). Fourteen additional procedures were performed on 12 patients. Annular abscess was present in 73.3% of cases and required annulus patch repair in 13/22 (59%). Early reoperation rate was 20%, mostly for surgical bleeding. One- and 5-year actuarial survival rates were 90.0 and 82.2%, respectively. There were no cases of relapse, and reinfection-free survival was 86.7% at 1 year and 75.5% at 5 years. Postoperative mean and maximal transvalvular gradients were 7 (IQR 3.3 mmHg) and 14.6 mmHg (IQR 4.6 mmHg), respectively.ConclusionsThe Medtronic Freestyle bioroot could be a valid alternative to homografts for the treatment of infective endocarditis, particularly in cases necessitating aortic root reconstruction after extensive debridement of annular abscesses, with comparable outcomes and potential advantages in terms of durability and availability.

Project description:Background Infective endocarditis (IE) after pulmonary valve replacements in congenital heart disease is a significant concern. This study aimed to identify specific long-term risk factors for IE after percutaneous pulmonary valve implantation or surgical pulmonary valve replacement. Methods and Results All patients with congenital heart disease from the National Register for Congenital Heart Defects with at least 1 pulmonary valve replacement before January 2018 were included. A total of 1170 patients (56.3% men, median age at study inclusion 12 [interquartile range {Q1-Q3} 5-20 years]) received 1598 pulmonary valve replacements. IE occurred in 4.8% of patients during a follow-up of total 9397 patient-years (median 10 [Q1-Q3, 6-10] years per patient). After homograft implantation 7 of 558 (1.3%) patients developed IE, after heterograft implantation 31 of 723 (4.3%) patients, and after Melody valve implantation 18 of 241 (7.5%) patients. Edwards Sapien and mechanical valves were used less frequently and remained without IE. The incidence of IE in heterografts excluding Contegra valves was 7 of 278 (2.5%), whereas the incidence of IE in Contegra valves was 24 of 445 (5.4%). The risk of IE was not increased compared with homografts if Contegra valves were excluded from the heterografts (hazard ratio [HR], 2.60; P=0.075). The risk of IE was increased for bovine jugular vein valves, Contegra valves (HR, 6.72; P<0.001), and Melody valves (HR, 5.49; P<0.001), but did not differ between Melody valves and Contegra valves (HR, 1.01; P=0.978). Conclusions Bovine jugular vein valves have the highest risk of IE, irrespective of the mode of deployment, either surgical or percutaneous.

Project description:Background Data comparing the frequency and outcomes of infective endocarditis (IE) after transcatheter (TAVR) to surgical aortic valve replacement (SAVR) are scarce. The objective of this study is to compare the incidence and outcomes of IE after TAVR using a supra-annular, self-expanding platform (CoreValve and Evolut) to SAVR. Methods and Results Data of 3 randomized clinical trials comparing TAVR to SAVR and a prospective continued TAVR access study were pooled. IE was defined on the basis of the modified Duke criteria. The cumulative incidence of IE was determined by modeling the cause-specific hazard. Estimates of all-cause mortality were calculated by means of the Kaplan-Meier method. Outcomes are reported for the valve-implant cohort. During a mean follow-up time of 2.17±1.51 years, 12 (0.5%) of 2249 patients undergoing TAVR and 21 (1.1%) of 1828 patients undergoing SAVR developed IE. Patients with IE more frequently had diabetes mellitus than those without (57.6% versus 34.2%; P=0.005). The cumulative incidence of IE was 1.01% (95% CI, 0.47%-1.96%) after TAVR and 1.58% (95% CI, 0.97%-2.46%) after SAVR (P=0.047) at 5 years. Among patients with IE, the rate of all-cause mortality was 27.3% (95% CI, 1.0%-53.6%) in the TAVR and 51.8% (95% CI, 28.2%-75.3%) in the SAVR group at 1 year (log-rank P=0.15). Conclusions Pooled prospectively collected data comparing TAVR with a supra-annular, self-expanding device to SAVR showed a low cumulative risk of IE irrespective of treatment modality, although the risk was lower in the TAVR implant group. Once IE occurred, mortality was high. Registration URL: https://www.clinicaltrials.gov; Unique identifiers: NCT01240902, NCT01586910, NCT02701283.

Project description:ObjectivesMitral valve repair in native active infective endocarditis is technically challenging. The survival benefit over valve replacement is poorly established and possibly absent because of the high risk of repair failure and reoperation. In this study, we explore the results of our structured approach in these patients.MethodsBetween January 2000 and January 2017, 149 patients underwent surgery for native mitral infective endocarditis. Among them, 97 (66%) patients underwent valve repair and 52 (34%) underwent valve replacement. Our structured approach consisted of early surgery, radical resection of infected tissue, liberal use of prosthetic materials and 'patch' repair techniques. A critical assessment of expected repair durability was made intraoperatively and repair was not performed if concerns of long-term durability existed. To study the effects of valve repair on overall survival, landmark analysis was performed.ResultsIn-hospital mortality was 15.4% (14 repair vs 9 replacement patients; P = 0.642). There were no residual infective endocarditis cases or early reoperations. On Cox proportional hazards analysis, valve replacement was not inferior to repair within 1-year post-surgery [hazard ratio (HR) 1.134, 95% confidence interval (CI) 0.504-2.540; P = 0.76]. Beyond 1 year post-surgery, replacement was associated with decreased survival (HR 2.534, 95% CI 1.002-6.406; P = 0.049). There were no differences in freedom from recurrent infective endocarditis (P = 0.47) and mitral valve reintervention (P = 0.52).ConclusionsActive mitral valve endocarditis remains a complex disease with significant early and late morbidity and mortality. A structured approach allows valve repair in two-thirds of patients. Clinical results could be improved by focussing on early surgery, prior to extensive valve destruction, to enable durable repairs and improve late outcomes.

Project description:Lactococcus garvieae is a fish pathogen and an uncommon cause of human infections. There is a growing body of evidence showing its potential for causing endocarditis especially in those with prior valve surgery. In this case report, we present what we believe is the first case of endocarditis by L. garvieae affecting a valve-in-valve transcatheter aortic valve replacement that was successfully treated. Specific guidelines for the management of these patients are lacking. Our experience can contribute to the current knowledge regarding this life-threatening infection as well as to the future care of these patients. We aim to emphasize that despite not being recognized as a typical endocarditis microorganism by the Duke Criteria, the possibility of endocarditis needs to be highly entertained in patients with L. garvieae bacteremia, especially when prosthetic valves are present. Consequently, clinicians should pursue further this diagnosis with transesophageal echocardiogram and/or alternative imaging modalities (e.g., PET-CT scan and MRI) regardless of an initial negative transthoracic echocardiogram. Reaching a diagnosis of L. garvieae endocarditis led us to the decision of prolonging the antibiotic course for 6 weeks with successful results. Ultimately, surgery was not required owing to the absence of prosthetic aortic valve dysfunction and paravalvular extension of the infection.

Project description:Aorto-cavitary fistula is a rare condition, and the most common underlying aetiology is infective endocarditis (IE) of the native or the prosthetic aortic valve. We report a case of aorto-right inferior pulmonary venous fistula following redo mitral valve replacement (MVR) for prosthetic mitral valve IE. A 74-year-old woman underwent urgent redo MVR for prosthetic mitral valve IE. The post-operative course was complicated with heart failure and mediastinal haematoma compressing the left atrium. The haematoma was surgically removed and laceration of the left atrial wall was suture ligated; this was attributed to the surgical trauma dissection of the adhesive tissues. One-week post-operatively, a continuous murmur emerged, which prompted an evaluation of the left to right shunt. Transthoracic echocardiography revealed an echolucent area posterior to the aorta, with continuous flow on colour Doppler. Three-dimensional computed tomography showed a fistula between the aorta and the right inferior pulmonary vein. There was a high risk involved in surgical management; therefore, she was managed medically. Fortunately, the continuous murmur and echolucent space disappeared after 6 months. The fistula was considered to be obstructed by spontaneous thrombus formation in the narrowed segment of the fistula tract. The cause of fistula was attributed to possible surgical trauma in the presence of infection. The present case was unique, as it showed spontaneous healing of an aorto-cavitary fistula, which is very rare. The patient was alive with good health status, 6 years after the MVR.
