Right Heart Reverse Remodeling and Prosthetic Valve Function After Transcatheter vs Surgical Pulmonary Valve Replacement. JACC Cardiovasc Interv 2024; 17:248-258. [PMID: 38267139 DOI: 10.1016/j.jcin.2023.11.030] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Revised: 11/15/2023] [Accepted: 11/16/2023] [Indexed: 01/26/2024]
Abstract
BACKGROUND There are limited data about postprocedural right heart reverse remodeling and long-term prosthesis durability after transcatheter pulmonary valve replacement (TPVR) and how these compare to surgical pulmonary valve replacement (SPVR). OBJECTIVES This study sought to compare right heart reverse remodeling, pulmonary valve gradients, and prosthetic valve dysfunction after TPVR vs SPVR. METHODS Patients with TPVR were matched 1:2 to patients with SPVR based on age, sex, body surface area, congenital heart lesion, and procedure year. Right heart indexes (right atrial [RA] reservoir strain, RA volume index, RA pressure, right ventricular [RV] global longitudinal strain, RV end-diastolic area, and RV systolic pressure) were assessed at baseline (preintervention), 1 year postintervention, and 3 years postintervention. Pulmonary valve gradients were assessed at 1, 3, 5, 7, and 9 years postintervention. RESULTS There were 64 and 128 patients in the TPVR and SPVR groups, respectively. Among patients with TPVR, 46 (72%) and 18 (28%) received Melody (Medtronic) vs SAPIEN (Edwards Lifesciences) valves, respectively. The TPVR group had greater postprocedural improvement in RA reservoir strain and RV global longitudinal strain at 1 and 3 years. The TPVR group had a higher risk of prosthetic valve dysfunction mostly because of a higher incidence of prosthetic valve endocarditis compared to SPVR but a similar risk of pulmonary valve reintervention because some of the patients with endocarditis received medical therapy only. Both groups had similar pulmonary valve mean gradients at 9 years postintervention. CONCLUSIONS These data suggest a more favorable right heart outcome after TPVR. However, the risk of prosthetic valve endocarditis and prosthetic valve dysfunction remains a major concern.

Abstract
Pulmonary valve replacement (PVR) is the most common cardiac operation in adult patients with congenital heart disease (ACHD). It can improve right ventricular outflow tract (RVOT) obstruction, typically due to pulmonary valve stenosis or regurgitation. PVR can be performed surgically (open-heart) and through a transcatheter (percutaneous) method, which is minimally invasive and is associated with shorter hospitalization stays. However, following PVR, infectious endocarditis (IE) can complicate the recovery process and increase mortality in the long term. IE is a rare but deadly multi-organ system condition caused by microorganisms traversing the bloodstream from a specific entry point. It can have many presentations, such as splinter hemorrhages, fevers, and vegetation on valves that lead to stroke consequences. This paper aims to evaluate the differences in the rate, etiology, manifestations, treatment, and outcomes of IE following surgical and transcatheter PVR, as the goal is to perform a procedure with few complications. In both approaches, Staphylococcus aureus was the most common microorganism that affected the valves, followed by Streptococcus viridians. Research has shown that surgical pulmonary valve replacement (SPVR) has a decreased risk of IE following surgery compared to TPVR. However, TPVR is preferred due to the reduced overall risk and complications of the procedure. Despite this, the consensus on mortality rates does differ. Future research should consider the type of valves used for transcatheter pulmonary valve replacement (TPVR), such as Melody valves versus Edward Sapien valves, as their IE rates vary significantly.

Infective endocarditis after transcatheter pulmonary valve implantation in patients with congenital heart disease: Distinctive features. Arch Cardiovasc Dis 2023; 116:159-166.

Abstract
The introduction of transcatheter pulmonary valve implantation (TPVI) has greatly benefited the management of right ventricular outflow tract dysfunction. Infective endocarditis (IE) is a feared complication of TPVI that affects valve durability and patient outcomes. Current recommendations provide only limited guidance on the management of IE after TPVI (TPVI-IE). This article, by a group of experts in congenital heart disease in children and adults, interventional cardiology, infectious diseases including IE, and microbiology, provides a comprehensive review of the current evidence on TPVI-IE, including its incidence, risk factors, causative organisms, diagnosis, and treatment. The incidence of TPVI-IE varies from 13-91/1000 person-years for Melody valves to 8-17/1000 person-years for SAPIEN valves. Risk factors include history of IE, DiGeorge syndrome, immunosuppression, male sex, high residual transpulmonary gradient and portal of bacteria entry. Staphylococci and streptococci are the most common culprits, whereas Staphylococcus aureus is associated with the most severe disease. In addition to the modified Duke criteria, a high residual gradient warrants a strong suspicion. Imaging studies are helpful for the diagnosis. Intravenous antibiotics guided by blood culture results are the mainstay of treatment. Invasive re-intervention may be required. TPVI-IE in patients with congenital heart disease exhibits several distinctive features. Whether specific valve types are associated with a higher risk of TPVI-IE requires further investigation. Patient and parent education regarding IE prevention may have a role to play and should be offered to all patients.

Abstract
The 2007 American Heart Association (AHA) guidelines limited antibiotic prophylaxis (AP) for infective endocarditis (IE) to fewer patients with predisposing cardiac conditions (PCC). We surveyed the American Academy of Pediatrics Section on Cardiology and Cardiac Surgery (AAP SOCCS) on their recommendations for AP for a number of PCC and procedures. We report on those 173 respondents who follow the 2007 AHA guidelines. AP rates for high-risk PCCs clearly meeting AHA criteria ranged from 70.5-89.8%. Conversely, for PCCs which did not meet AHA criteria, prescribing rates varied from <1% to 29.5%. PCC for which AP indication was unclear per guidelines, AP rates similarly varied from 9.9-39.8%. Similar variability is noted in AP for various procedures in setting of high-risk PCC. There is variability in AP prescribing practices among pediatric cardiologists based on both underlying PCC and noncardiac procedures in the setting of underlying cardiac disease.

Abstract
BACKGROUND Infective endocarditis is a major threat after prosthetic pulmonary valve replacement. Early diagnosis may improve outcomes. METHODS A structured patient education programme for prevention and early diagnosis of infective endocarditis was developed at our institution since 2016. Time delay between onset of symptoms of prosthetic pulmonary valve endocarditis and its diagnosis (defined as initiation of appropriate high-dose intravenous antibiotic treatment) was compared for patients presenting before (cohort 1) and after (cohort 2) initiation of the patient education programme. RESULTS Between 2008-2019, 26 patients (median age 24.9, range: 16.8-62.0 years, 73% male) were diagnosed with prosthetic pulmonary valve endocarditis, 13 patients (cohort 1) before (1.7 cases/year) and 13 patients (cohort 2) after June 2016 (3.7 cases/year). There were no differences in baseline characteristics or clinical presentation between the study cohorts. Overall, the median delay between onset of symptoms and diagnosis of infective endocarditis was 6 days (range: 0-133 days) with a significantly longer delay among patients in cohort 1, compared to cohort 2 (25 days, range: 5-133 days versus 3 days, range: 0-13 days, p < 0.0001). A delay of >7 days was documented in 11/13 patients (85%) in cohort 1 as compared to 1/13 (8%) in cohort 2 (p < 0.001). Need for urgent valve replacement or permanent deterioration of prosthetic valve function was higher in cohort 1, compared to cohort 2 (11/13, 85% versus 5/13, 39%; p = 0.041). CONCLUSIONS Prosthetic pulmonary valve endocarditis is increasingly recognised. A structured patient education programme may improve early diagnosis and clinical outcomes.

Abstract
Right ventricular outflow tract (RVOT) reconstruction is a common surgical method to treat congenital cardiac lesions, and bovine jugular vein conduit (BJVC) has become a prevalent candidate of prosthetic material for this procedure since 1999. Although many clinical studies have shown encouraging results on BJVCs, complications such as stenosis, aneurysmal dilatation, valve insufficiency, and infective endocarditis revealed in other clinical outcomes still remain problematic. This review describes the underlying mechanisms causing respective complications, and summarizes the current technological development that may address those causative factors. Novel crosslinking agents, decellularization techniques, conduit coatings, and physical reinforcement materials have improved the performances of BJVCs. The authors expect that the breakthroughs in the clinical application of BJVC may come from new genetic research findings and advanced characterization apparatuses and bioreactors, and are optimistic that the BJVC will in the future provide sophisticated therapies for next-generation RVOT reconstruction.

Abstract
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.

Abstract
OBJECTIVES Percutaneous pulmonary valve prostheses and right ventricle-to-pulmonary artery conduits are at risk for infective endocarditis (IE). In children and adults with a congenital heart disease, a pulmonary valve implant is frequently necessary. Prosthetic valve endocarditis is a conservatively barely manageable, serious life-threatening condition. We investigated the results of surgical pulmonary valve replacements in patients with IE. METHODS A total of 20 patients with congenital heart disease with the definite diagnosis of IE between March 2013 and July 2020 were included in this single institutional, retrospective review. Infected conduits were 11 Melody, 5 Contegra, 3 homografts and 1 Matrix P Plus. All of the infected prosthetic material was removed from the right ventricular outflow tract up to the pulmonary bifurcation. Pulmonary homografts were implanted after pulmonary root resection as right ventricle-to-pulmonary artery conduits. RESULTS All patients survived and were discharged infection-free. The mean time from the conduit implant to the operation for IE was 4.9 years [95% confidence interval (CI), 3.0-6.9]. The median intensive care unit stay was 3.0 days (95% CI, 2.0-4.7), and the median hospital time was 25.0 days (95% CI, 19.2-42.0). Median follow-up time was 204.5 days (range 30 days to 5 years) without death or recurrent endocarditis. CONCLUSIONS The surgical treatment of IE of percutaneous pulmonary valve prostheses and right ventricle-to-pulmonary artery conduits is a safe and effective therapeutic concept. Early surgical referral of patients with suspicion of IE should be pursued to avoid sequelae such as right ventricular failure, septic emboli, intracardiac expansion and antibiotic resistance.

Abstract
OBJECTIVES Although homografts are often the preferred valve conduits for right ventricular outflow tract (RVOT) reconstruction, data on long-term homograft-related outcomes, durability and impact on quality of life (QoL) are scarce. The aim of this study was therefore to describe the long-term homograft function, clinical outcomes and QoL after RVOT reconstruction. METHODS We performed a single-centre retrospective analysis of all consecutive patients who underwent RVOT reconstruction with a homograft. Multiple subsequent allografts in the same patients were regarded as separate subjects. Valve-related events were analysed by Kaplan-Meier and Life Table methods. Serial echocardiographic measurements were analysed with mixed effects models. In addition, QoL was repeatedly assessed and compared with a matched general population. RESULTS In total, 701 consecutive homografts were implanted in 604 patients [59.6% males, mean age at operation 19.5 ± 15.2 (standard deviation)]. Hospital mortality was 3.3%. After 25 years follow-up, survival and freedom from valve replacement were 84 ± 4% and 56 ± 6%, respectively. Freedom from valve replacement after 15 years for patients under 1 year of age was 28 ± 14% years, for those between 1 and 18 years, 59 ± 8%, and for those older than 18 years, 82 ± 5%. The peak gradient increased predominantly in the first postoperative decade in infants and paediatric patients from 19 to 54 mmHg. In adults, the average gradient increased from 9 to 31 mmHg after 14 years. Compared to a gender- and age-matched Dutch population, patients reported lower vitality and general health but less bodily pain. Patients, in whom QoL was repeatedly assessed, reported lower scores on physical functioning and vitality after a 5-year follow-up period. However, we found no differences in any of the subscales in patients who underwent valve replacement during the 5-year interval. CONCLUSIONS Homografts are a durable valve alternative for RVOT reconstruction; in particular, adults show extensive freedom from valve replacement and report QoL comparable with healthy subjects. An online interactive application form created by our institution can be used to assess patient outcome after RVOT reconstruction with a homograft for different patient profiles.

Abstract
BACKGROUND Multiple congenital cardiac malformations require pulmonary valve replacement and/or right ventricular outflow (RVOT) reconstruction. Pulmonary valve replacement remains challenging in children owing to the limited growth potential of prosthetic valves. We evaluated outcomes in patients undergoing surgical implantation of a Melody valve in the RVOT. METHODS Data were retrospectively collected for 23 patients undergoing surgical Melody valve implantation at Boston Children's Hospital between 2009 and 2019. We assessed postoperative valve function, reintervention rates, and mortality. RESULTS Median age was 1.7 years (range, 2 months to 6 years); 12 patients were aged greater than 2 years (52%). Diagnosis was tetralogy of Fallot in 15 patients (65%); 15 had a prior RVOT operation (65%). The Melody valve was dilated before surgery to a median diameter of 14 mm (range, 10-20 mm). No patients had acute pulmonary regurgitation. One required transcatheter RVOT reintervention before discharge. Median follow-up was 3.7 years (range, 0.02-8.7 years) with moderate or greater pulmonary regurgitation in 2 patients. Catheter-based interventions (mean, 0.83 ± 1.07/patient) occurred at a median of 1 year (range, 16 days to 5.4 years) and included valve expansion for somatic growth (n = 10) and subsequent valve-in-valve replacement (n = 3). Three patients (13%) required surgical valve explant or replacement at a median of 1.0 year (range, 0.6-3.7 years) for Melody-specific indications. One-, 3-, and 5-year freedom from Melody-driven reoperation was 90%, 90%, and 83%, respectively. CONCLUSIONS The Melody valve can be surgically implanted in the RVOT of young patients with acceptable early results. These valves can be successfully dilated through transcatheter reintervention to accommodate growth.

The epidemiology of infective endocarditis with focus on non-device related right-sided infective endocarditis: A retrospective register-based study in the region of Southern Denmark. Int J Infect Dis 2020; 95:224-230. [PMID: 32289560 DOI: 10.1016/j.ijid.2020.04.011] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2020] [Revised: 04/03/2020] [Accepted: 04/06/2020] [Indexed: 01/05/2023] Open
Abstract
AIMS Non-device related right-sided infective endocarditis (ND-RSIE) is not well characterized. We aimed to characterize patients with infective endocarditis (IE) with emphasis on the epidemiology, clinical characteristics and complications of ND-RSIE. METHODS In this population-based cohort study, we identified patients with IE using ICD-10 codes from the Danish National Hospital Register in the Region of Southern Denmark between January 2007 and May 2017. Hospital records were reviewed, and characteristics and outcomes recorded. RESULTS We included 1243 confirmed IE episodes of which 82% were left-sided IE, 11% were cardiac device right sided infective endocarditis (RSIE) and 7% were ND-RSIE. Patients with ND-RSIE were considerably younger, had less comorbidity and had a lower 30-day mortality (6%) compared with patients with device RSIE (24%) and left-sided IE (26%) (p<0.01). ND-RSIE was associated with underlying heart disease, involvement of the tricuspid valve (57%), Staphylococcus species (53%) and complications (61%). Forty percent of ND-RSIE occurred among people who inject drugs (PWID) for whom significant differences were observed compared with non-PWID with regards to tricuspid valve involvement (96% vs. 32%), causative microorganisms (Staphylococcus aureus 79% vs. 27%), complications (86% vs. 45%), recurrence (29% vs. 11%) and 30-day mortality (0% vs. 7%). CONCLUSION ND-RSIE is relatively rare and differs with regards to epidemiology, clinical characteristics and complications compared with left-sided IE and cardiac device RSIE, but has a favourable prognosis. Forty percent of ND-RSIE occurs among PWID, which is associated with frequent complications but a very low mortality.

Abstract
BACKGROUND Transcatheter pulmonary valve replacement (TPVR) has emerged as an alternative to surgery in patients with pulmonary valve dysfunction. METHODS We searched the Medline and Cochrane databases since their inception to January 2019 as well as references from article, for all publications comparing TPVR with surgical PVR (SPVR). Studies were considered for inclusion if they reported comparative data regarding any of the study endpoints. The primary endpoint was early mortality after PVR. Secondary endpoints included procedure-related complications, length of hospital stay, mortality during follow-up, infective endocarditis, need for reintervention, post-PVR transpulmonary peak systolic gradient, and significant pulmonary regurgitation. RESULTS There were no differences in perioperative mortality between groups (0.2% vs 1.2%; pooled odds ratio, 0.56; 95% confidence interval, 0.19-1.59; P = .27, I2 = 0%). However TPVR conferred a significant reduction in procedure-related complications and length of hospital stay compared with SPVR. Midterm mortality and the need for repeat intervention were similar with both techniques, but pooled infective endocarditis was significantly more frequent in the TPVR group (5.8 vs 2.7%; pooled odds ratio, 3.09; 95% confidence interval, 1.89-5.06; P < .001, I2 = 0%). TPVR was associated with less significant PR and a trend towards a lower transpulmonary systolic gradient during follow-up. CONCLUSIONS TPVR is a safe alternative to SPVR in selected patients and is associated with a shorter length of hospital stay and fewer procedure-related complications. At midterm follow-up TPVR was comparable with SPVR in terms of mortality and repeat intervention but was associated with an increased risk of infective endocarditis.

Abstract
BACKGROUND The risk of endocarditis varies with CHD complexity and the presence of prosthetic valves. The purpose of the study was therefore to describe incidence and outcomes of prosthetic valve endocarditis in adults with repair tetralogy of Fallot. METHODS Retrospective review of adult tetralogy of Fallot patients who underwent prosthetic valve implantation, 1990-2017. We defined prosthetic valve endocarditis-related complications as prosthetic valve dysfunction, perivalvular extension of infection such abscess/aneurysm/fistula, heart block, pulmonary/systemic embolic events, recurrent endocarditis, and death due to sepsis. RESULTS A total of 338 patients (age: 37 ± 15 years) received 352 prosthetic valves (pulmonary [n = 308, 88%], tricuspid [n = 13, 4%], mitral [n = 9, 3%], and aortic position [n = 22, 6%]). The annual incidence of prosthetic valve endocarditis was 0.4%. There were 12 prosthetic valve endocarditis-related complications in six patients, and these complications were prosthetic valve dysfunction (n = 4), systemic/pulmonary embolic events (n = 2), heart block (n = 1), aortic root abscess (n = 1), recurrent endocarditis (n = 2), and death due to sepsis (n = 1). Three (50%) patients required surgery at 2 days, 6 weeks, and 23 weeks from the time of prosthetic valve endocarditis diagnosis. Altogether three of the six (50%) patients died, and one of these deaths was due to sepsis. CONCLUSIONS The incidence, complication rate, and outcomes of prosthetic valve endocarditis in tetralogy of Fallot patients underscore some of the risks of having a prosthetic valve. It is important to educate the patients on the need for early presentation if they develop systemic symptoms, have a high index of suspicion for prosthetic valve endocarditis, and adopt a multi-disciplinary care approach in this high-risk population.

Abstract
Background Transcatheter pulmonary valve replacement (TPVR) has currently been a well-established alternative operation method to surgical pulmonary valve replacement (SPVR) in patients with pulmonary valve dysfunction in the form of stenosis and/or regurgitation. We conducted a meta-analysis to evaluate the main clinical outcomes after TPVR and SPVR. Methods We systematically searched the references of relevant literatures from PubMed and the Cochrane Library published between January 2000 and December 2018 and followed The Preferred Reporting Items for Systematic reviews and Meta-analysis (PRISMA) for this study. Results Eleven studies with 4,364 patients were included in the study. Compared with SPVR, TPVR results in a significant decreased in-hospital mortality [odds ratio (OR): 0.18; 95% confidence interval (CI): 0.03-0.98] and mortality at the longest reported follow-up time point (OR: 0.43; 95% CI: 0.22-0.87), though 30-day mortality (OR: 0.38; 95% CI: 0.11-1.33) has no significant difference between groups. Days of hospital stay [(mean difference (MD): -4.38; 95% CI: -6.24--2.53] is shorter with TPVR than SPVR. Besides, rates of 30-day readmission (OR: 0.67; 95% CI: 0.50-0.91) and recurrent pulmonary regurgitation (OR: 0.17; 95% CI: 0.07-0.42) are lower with TPVR, whereas postprocedural infective endocarditis (IE) (OR: 4.56; 95% CI: 2.03-10.26) are higher with TPVR. SPVR carries a decreased risk of re-operation (OR: 2.19; 95% CI: 0.62-7.76) though without statistically significance. Conclusions In conclusion, TPVR is associated with a significantly decreased mortality, a shorter length of hospital-stay, a lower rate of 30-day readmission and recurrent pulmonary regurgitation as compared to SPVR throughout the follow-up duration, whereas SPVR results in a significantly lower rate of postprocedural IE than TPVR. In addition, SPVR carries a decreased risk of re-operation with statistically insignificance.

Abstract
Patients with congenital heart disease (CHD) with right ventricle outflow tract (RVOT) dysfunction need sequential pulmonary valve replacements throughout their life in the majority of cases. Since their introduction in 2000, the number of percutaneous pulmonary valve implantations (PPVI) has grown and reached over 10,000 procedures worldwide. Overall, PPVI has been proven safe and effective, but some anatomical variations can limit procedural success. This review discusses the current status and future perspectives of the procedure.

Abstract
Right ventricular outflow tract diseases are historically outcomes of surgical reconstruction for heart defects in neonates or children (Tetralogy of Fallot, Ross surgery). This kind of surgery performed during childhood lead often to dysfunctional right ventricular outflow tract (stenosis, leak) in older infants or young adults. In this case, reintervention on the right ventricular outflow tract would be associated with a high surgical risk. Development of the first percutaneous valves in the year 2000 paved the way for the pulmonary revalvulation. This percutaneous procedure has emerged as a credible alternative to the surgery for multioperated high risk patients with congenital cardiopathies. Two valves are currently available on the French market (Melody®, Sapien®); they cover all therapy indications, except the example of very wide outflow tracts which remain a surgical issue. Medical teams in charge of these young patients have to be enough trained in order to limit risks during the procedure. To this end, several teams promote the percutaneous pulmonary revalvulation over surgical revalvulation, this latter becoming limited only to cases in which percutaneous treatment is not feasible.

Abstract
BACKGROUND Endocarditis has emerged as one of the most concerning adverse outcomes in patients with congenital anomalies involving the right ventricular outflow tract (RVOT) and prosthetic valves. OBJECTIVES The aim of this study was to evaluate rates and potential risk factors for endocarditis after transcatheter pulmonary valve replacement in the prospective Melody valve trials. METHODS All patients in whom a transcatheter pulmonary valve (TPV) was implanted in the RVOT as part of 3 prospective multicenter studies comprised the analytic cohort. The diagnosis of endocarditis and involvement of the TPV were determined by the implanting investigator. RESULTS A total of 309 patients underwent transcatheter pulmonary valve replacement (TPVR) and were discharged with a valve in place. The median follow-up duration was 5.1 years, and total observation until study exit was 1,660.3 patient-years. Endocarditis was diagnosed in 46 patients (median 3.1 years after TPVR), and a total of 35 patients were reported to have TPV-related endocarditis (34 at the initial diagnosis, 1 with a second episode). The annualized incidence rate of endocarditis was 3.1% per patient-year and of TPV-related endocarditis was 2.4% per patient-year. At 5 years post-TPVR, freedom from a diagnosis of endocarditis was 89% and freedom from TPV-related endocarditis was 92%. By multivariable analysis, age ≤12 years at implant (hazard ratio: 2.3; 95% confidence interval: 1.2 to 4.4; p = 0.011) and immediate post-implant peak gradient ≥15 mm Hg (2.7; 95% confidence interval: 1.4 to 4.9; p = 0.002) were associated with development of endocarditis and with development of TPV-related endocarditis (age ≤12 years: 2.8; 95% confidence interval: 1.3 to 5.7; p = 0.006; gradient ≥15 mm Hg: 2.6; 95% confidence interval: 1.3 to 5.2; p = 0.008). CONCLUSIONS Endocarditis is an important adverse outcome following TVPR in children and adults with post-operative congenital heart disease involving the RVOT. Ongoing efforts to understand, prevent, and optimize management of this complication are paramount in making the best use of TPV therapy.

Abstract
AIMS The aim of the study was to evaluate the midterm safety and efficacy of a self-expanding valve (Venus P-valve) in the treatment of patients with pulmonary regurgitation and a native right ventricular outflow tract (RVOT) in China. METHODS AND RESULTS Patients who had moderate or severe pulmonary regurgitation after surgical repair of the RVOT with a transannular or RVOT patch were included in the study. Fifty-five patients (67% female; average age 28.7±12.4 years) from six different hospitals in China were enrolled. The procedure success rate was 98.2%. In the one failure, the patient experienced valve dislodgement two days after the procedure. During the 12-month follow-up, two patients died, one due to infective endocarditis. Three other patients developed infective endocarditis. Two patients developed atrial flutter, and one patient had a pulmonary embolism. Echocardiography examinations at 12 months showed that two patients had mild pulmonary regurgitation, and 19 patients had trace pulmonary regurgitation. No paravalvular regurgitation occurred. The mean peak pulmonary gradient was 16.3±7.4 (range 4-38) mmHg. Compared with the baseline data, the right ventricular end-diastolic volume index (RVEDVI) was reduced from 137.6±15.8 mL/m2 to 83.9±16.0 mL/m2 (p<0.001), and the New York Heart Association (NYHA) class was significantly improved (p<0.01). CONCLUSIONS The one-year results of the China Venus P-valve study show considerable promise for a hitherto unmet need in patients with pulmonary regurgitation and an enlarged native RVOT.

Abstract
We report a case of an 18-year-old woman who presented with infective endocarditis (IE), in two conduits percutaneously delivered in the right ventricle outflow tract ("double-barrel endocarditis"). The patient's clinical presentation, echocardiogram findings, infectious agent, clinical management, surgical approach, and follow-up assessment are described. Percutaneous pulmonary valve implantation has emerged as a viable therapy for conduit dysfunction in the right ventricular outflow tract. Although the percutaneous approach has several advantages, this strategy and the valves used are not complication-free. IE after transcatheter valve deployment has evoked the growing concern, as there is a higher incidence in these patients compared with patients with surgically repaired pulmonary valves. As a result, this type of surgical treatment is especially important.

Can J Cardiol 2019; 35:721-726. [PMID: 31151707 DOI: 10.1016/j.cjca.2019.02.006] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2019] [Revised: 02/06/2019] [Accepted: 02/10/2019] [Indexed: 11/15/2022] Open
Abstract
BACKGROUND Lesion complexity and prosthetic valves are known risk factors for infective endocarditis in patients with congenital heart disease. Tetralogy of Fallot (TOF) is the most common complex/cyanotic congenital heart disease and often requires prosthetic valve implantation. Population-based risk of endocarditis in TOF patients is unknown. METHODS We reviewed the National Inpatient Sample (NIS) and identified admissions in TOF patients (>18 years), 2000 to 2014. The primary outcome was to describe incidence of endocarditis-related admissions. To assess trends, we divided the study period into tertiles: early (2000 to 2004), mid (2005 to 2009) and late (2010 to 2014) eras. The secondary outcome was to compare in-hospital mortality, complications, and health care resource utilization between admissions with and without endocarditis. RESULTS There were 393 (2.1%) endocarditis-related admissions among 18,353 admissions, and the incidence of endocarditis-related admissions increased over time: 1.9% (early era) vs 2.2% (mid-era) vs 2.4% (late era), P < 0.001. Overall in-hospital mortality was 6%. In addition to previously described risk factors for endocarditis, such as previous pacemaker/defibrillator or prosthetic valve implantation, we observed an association between endocarditis-related admissions and male gender, black race, and lower socioeconomic class. In comparison with admissions without endocarditis, the endocarditis-related admissions had higher in-hospital mortality, complications, and health care resource utilization measured by length of stay, inflation-adjusted hospitalization cost, and type of hospital discharge. CONCLUSIONS Incidence of endocarditis-related admissions increased over time and was associated with higher mortality, complications, and health care resource utilization. Further studies are required to investigate the observed temporal increase in incidence of endocarditis and explore new strategies to improve outcomes.

Abstract
BACKGROUND Pulmonary valve replacement (PVR) is a common operation in patients with congenital heart disease (CHD). As survival with CHD improves, infective endocarditis (IE) is a growing complication after PVR. The aim of this study was to assess the incidence, risk factors, and clinical outcomes of IE after surgical PVR in patients with CHD at our institution. METHODS Retrospective analysis of all cases of surgical PVR performed at Children's Hospital of Wisconsin between 1975 and 2016 was performed. All cases of IE after PVR were identified and clinical and imaging data were obtained by review of medical records. RESULTS Out of 924 surgical PVRs, there were 19 (2%) cases of IE. The incidence of IE after surgical PVR was 333 cases per 100,000 person-years. The median age at diagnosis of IE was 21 years (range = 1.2-34 years) and the median time from PVR to diagnosis of IE was 9.4 years. The overall freedom from IE after PVR was 99.1%, 96.9%, and 93.4%, at 5, 10, and 15 years, respectively. There was no significant difference in freedom from IE based on valve type, including bovine jugular vein grafts. Patients with IE were more likely to have had a history of multiple PVRs, while length of follow-up after PVR, age at time of PVR, and gender were not significant risk factors. Eleven (58%) cases of IE required surgical intervention, while 8 (42%) were successfully treated with intravenous antibiotics alone. There were no deaths and no recurrences of IE after treatment. CONCLUSION The overall risk for IE after PVR is low. There was no association between age or type of pulmonary valve and risk of IE. The majority of cases require surgical intervention, but in general the outcomes of IE after PVR are good with low mortality and risk of recurrence.

Abstract
Percutaneous pulmonary valve implantation has been widely accepted as an alternative to surgery in selected patients with right ventricular outflow tract (RVOT) dysfunction. This totally new field of our specialty pushed centres to rethink overall strategies on how to treat RVOT dysfunction. In this review, we will focus on challenges related to patient selection, and discuss innovative procedural techniques developed over the years to enlarge the number of candidates for the technique.

Abstract
Background Infective endocarditis (IE) after transcatheter pulmonary valve implantation (TPVI) in dysfunctioning right ventricular outflow tract conduits has evoked growing concerns. We aimed to investigate the incidence and the natural history of IE after TPVI with the Melody valve through a systematic review of published data. Methods and Results PubMed, EMBASE, and Web of Science databases were systematically searched for articles published until March 2017, reporting on IE after TPVI with the Melody valve. Nine studies (including 851 patients and 2060 patient‐years of follow‐up) were included in the analysis of the incidence of IE. The cumulative incidence of IE ranged from 3.2% to 25.0%, whereas the annualized incidence rate ranged from 1.3% to 9.1% per patient‐year. The median (interquartile range) time from TPVI to the onset of IE was 18.0 (9.0–30.4) months (range, 1.0–72.0 months). The most common findings were positive blood culture (93%), fever (89%), and new, significant, and/or progressive right ventricular outflow tract obstruction (79%); vegetations were detectable on echocardiography in only 34% of cases. Of 69 patients with IE after TPVI, 6 (8.7%) died and 35 (52%) underwent surgical and/or transcatheter reintervention. Death or reintervention was more common in patients with new/significant right ventricular outflow tract obstruction (69% versus 33%; P=0.042) and in patients with non‐streptococcal IE (73% versus 30%; P=0.001). Conclusions The incidence of IE after implantation of a Melody valve is significant, at least over the first 3 years after TPVI, and varies considerably between the studies. Although surgical/percutaneous reintervention is a common consequence, some patients can be managed medically, especially those with streptococcal infection and no right ventricular outflow tract obstruction.

Abstract
AIMS The Xeltis bioabsorbable pulmonary valved conduit (XPV), designed to guide functional restoration of patients' own tissue, is potentially more durable than current pulmonary bioprosthetic valves/valved conduits. The aim of this study was to assess the haemodynamic performance of the novel XPV implanted in an ovine model. METHODS AND RESULTS The XPV was surgically implanted in adult sheep under general anaesthesia and cardiopulmonary bypass (XPV group, n=20). Sheep that received a Hancock bioprosthetic pulmonary valved conduit served as a control group (HPV group, n=3). Transthoracic echocardiograms from VARC-2 recommended time points at 3, 6, 9, 12, 18 and 24 months (XPV group) and at 3 and 6 months (HPV group) after the procedure were analysed in an independent core laboratory. The primary endpoint was favourable valved conduit performance, defined as peak systolic pressure gradient <40 mmHg, no severe pulmonary regurgitation (PR), and a maximum conduit patency index of -20%. In the latter, negative values denote luminal narrowing and vice versa. The valvular peak systolic pressure gradient (mmHg) was 25.6±9.7 (3 months), 19.6±7.1 (6 months), 10.0±9.2 (24 months) in the XPV group and 18.4±6.6 (3 months), 17.7±4.6 (6 months) in the HPV group. The patency index (%) of the conduit at the valvular level was +30.3±13.6 (6 months) and +64.1±1.4 (24 months) in the XPV group and +2.0±15.9 (6 months) in the HPV group. PR was trace or mild at all visits, except in one animal with persistent moderate PR in the XPV group, up to 24 months. CONCLUSIONS The XPV showed a favourable and durable haemodynamic performance (up to two years after implantation), without conduit narrowing/obstruction or severe regurgitation.

Abstract
The Bovine jugular vein (BJV) graft for right ventricular outflow tract reconstruction (RVOT) is limited applied due to possible graft failure. In this study, we reported the clinical application of simplified hand-sewn trileaflet valved conduit as an alternative for BJV graft. We retrospectively included 68 patients underwent 76 conduits implantation including 22 new simplified hand-sewn trileaflet valved conduits (Group A) and 54 BJV grafts (Group B). For patients in Group A, a hand-sewn trileaflet valved conduit with valves made of autologous pericardium or expanded polytetrafluoroethylene was applied. Baseline, perioperative, and outcomes were analyzed. No early mortality or perioperative complication occurred in Group A, while 2 patients died and 16 patients suffered from conduits failure due to conduits stenosis (n = 11), stenosis plus regurgitation (n = 3), and regurgitation alone (n = 2) in Group B. Freedom from BJV grafts failure within 1, 3, 5, and 7 years was 98.0%, 88.2%, 83.6% and 83.6% in Group A, and 98.0%, 85.8%, 76.8% and 62.1% in Group B. Endocarditis occurred in 9 patients in Group B, but not in Group A. Subsequent analysis showed that endocarditis is the only significant predictor of BJV grafts failure (odds ratio: 6.202, 95% confidence intervals 1.237∼31.108). The novel simplified hand-sewn trileaflet valved conduits seems to be associated with lower incidences of perioperative complication, graft failure, and early-phase mortality, as compared with conventional BJV grafts.

Abstract
OBJECTIVES This study compared the risk of infective endocarditis (IE) after percutaneous pulmonary valve implantation (PPVI) with the Sapien and Melody valves. BACKGROUND The incidence of IE after PPVI is estimated at 3% per year with the Melody valve. The Sapien valve is a more recently marketed valve used for PPVI. METHODS We retrospectively included consecutive patients who underwent PPVI at a single center between 2008 and 2016. IE was diagnosed using the modified DUKE criteria. RESULTS PPVI was performed in 79 patients (Melody valve, 40.5%; Sapien valve, 59.5%). Median age was 24.9 years (range 18.1 to 34.6). IE occurred in 8 patients (10.1%) at a median of 1.8 years (minimum: 1.0; maximum: 5.6) after surgery. Causative organisms were methicillin-sensitive Staphylococcus aureus (n = 3), Staphylococcus epidermidis (n = 1), Streptococcus mitis (n = 1), Aerococcus viridans (n = 1), Corynebacterium striatum (n = 1), and Haemophilus influenzae (n = 1). All 8 cases occurred after Melody PPVI (25.0% vs. 0.0%). The incidence of IE was 5.7% (95% confidence interval: 2.9% to 11.4%) per person-year after Melody PPVI. The Kaplan-Meier cumulative incidence of IE with Melody PPVI was 24.0% (95% confidence interval: 12.2% to 43.9%) after 4 years and 30.1% (95% confidence interval: 15.8% to 52.5%) after 6 years, compared with 0.0% with the Sapien PPVI after 4 years (p < 0.04 by log-rank test). There was a trend toward a higher incidence of IE in the first 20 patients with Melody PPVI (who received prophylactic antibiotics during the procedure only) and in patients who had percutaneous interventions, dental care, or noncardiac surgery after PPVI. CONCLUSIONS IE after PPVI may be less common with the Sapien compared with the Melody valve.

Sharma A, Cote AT, Hosking MCK, Harris KC. A Systematic Review of Infective Endocarditis in Patients With Bovine Jugular Vein Valves Compared With Other Valve Types. JACC Cardiovasc Interv 2017; 10:1449-1458. [PMID: 28728659 DOI: 10.1016/j.jcin.2017.04.025] [Citation(s) in RCA: 63] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2017] [Revised: 04/11/2017] [Accepted: 04/19/2017] [Indexed: 01/10/2023]
Abstract
OBJECTIVES The aim of this study was to systematically evaluate the incidence of infective endocarditis (IE) in right ventricle-to-pulmonary artery conduits and valves, comparing bovine jugular vein (BJV) valves with all others. BACKGROUND Recent evidence suggests that the incidence of IE is higher in patients with congenital heart disease who have undergone implantation of BJV valves in the pulmonary position compared with other valves. METHODS Systematic searches of published research were conducted using electronic databases (MEDLINE, Embase, and CINAHL) and citations cross-referenced current to April 2016. Included studies met the following criteria: patients had undergone right ventricle-to-pulmonary artery conduit or percutaneous pulmonary valve implantation, and investigators reported on the type of conduit or valve implanted, method of intervention (surgery or catheter based), IE incidence, and follow-up time. RESULTS Fifty studies (Levels of Evidence: 2 to 4) were identified involving 7,063 patients. The median cumulative incidence of IE was higher for BJV compared with other valves (5.4% vs. 1.2%; p < 0.0001) during a median follow-up period of 24.0 and 35.5 months, respectively (p = 0.03). For patients with BJV valves, the incidence of IE was not different between surgical and catheter-based valve implantation (p = 0.83). CONCLUSIONS There was a higher incidence of endocarditis with BJV valves than other types of right ventricle-to-pulmonary artery conduits. There was no difference in the incidence of endocarditis between catheter-based bovine valves and surgically implanted bovine valves, suggesting that the substrate for future infection is related to the tissue rather than the method of implantation.

Abstract
With new surgical techniques, more and more complex congenital heart defects are treated requiring sometimes right ventricle to pulmonary artery conduit implantation. In order to extend RV to PA conduit lifespan, 15 years ago a valved stent was developed. The implantation technique was progressively standardized to decrease risks of procedural complications. Medium and long-term hemodynamic results of the stent were so good that indications were broadened to native or complex right ventricular outflow tracts. Currently, 2 types of stents are implanted routinely: the Melody valve® (Medtronic, Minneapolis, USA) and the Sapien® valve (Edwards, Lifesciences, Irvine, USA). Other devices are evaluated in trials: thanks to their diabolo shape, implantation is feasible in large outflows tracts. The main source of worries is infective endocarditis. Numerous studies are conducted in order to identify risks factors, prevention and optimal treatment of this complication. In the near future, new devices and new implantation strategies will make this technology available for a larger number of patients.

Abstract
BACKGROUND Bovine jugular vein (BJV) conduits are widely applied for surgical reconstruction of the right ventricular outflow tract (RVOT). However, relevant studies of valve failure rates and the related risk factors are limited in China. The aim of this study was to assess the BJV prognosis after medium- to long-term follow-up. METHODS Fifty-three hospital patients implanted with BJV conduits from January 2002 to December 2013 were recruited. Patient information and follow-up prognosis were reviewed retrospectively. Conduit stenosis and failure as well as endocarditis were diagnosed. RESULTS The total person years was 345.5, and the median follow-up time was 6.3 years. Early mortality occurred in two patients, and there was no late mortality. BJV conduit failure occurred in 15 patients (29.4%) due to severe stenosis (n=10), stenosis plus regurgitation (n=3), and regurgitation alone (n=2). The proportion of patients who were free of BJV conduit failure at 1, 3, 5, and 7 years was 98.0%, 85.8%, 76.8%, and 62.1%, respectively. There were nine cases of endocarditis (17.0%). Multivariate logistic regression analysis showed that endocarditis was a significant risk factor associated with BJV conduit failure (OR: 6.735; 95% CI: 1.348-33.647). CONCLUSIONS The durability of BJV conduits was suboptimal after a mid-term follow-up period. Endocarditis was found to be a significant risk factor that accelerates BJV conduit deterioration.

Abstract
Percutaneous pulmonary valve replacement has emerged as an alternative to operation for some patients with congenital heart disease requiring intervention. Endocarditis is increasingly described as an adverse event during follow-up [1-4]. Diagnosis is difficult because of the poor visualization of the prosthetic valve in the pulmonary position by transthoracic and transesophageal echocardiogram and by the metallic artifact that degrades the image quality of magnetic resonance imaging (MRI). Two cases of percutaneous pulmonary valve obstruction diagnosed by cardiac computed tomographic angiography are presented. These cases demonstrate the utility of cardiac computed tomography for noninvasive imaging of suspected thrombus or endocarditis in a percutaneously placed pulmonary valve.

Abstract
BACKGROUND Percutaneous pulmonary valve implantation (PPVI) using the bovine jugular vein Melody(®) valve (Medtronic Inc., Minneapolis, MN, USA) is safe and effective. However, post-procedural complications have been reported, the reasons for which are unclear. OBJECTIVE To assess the impact of PPVI procedural steps on valvular histology and leaflet mechanical behaviour. METHODS Three different valved stents (the Melody(®) valve and two homemade stents with bovine and porcine pericardium) were tested in vitro under four conditions: (1) control group; (2) crimping; (3) crimping plus inflation of low-pressure balloon; (4) condition III plus post-dilatation (high-pressure balloon). For each condition, valvular leaflets (and a venous wall sample for Melody(®) stents) were taken for histological analysis and mechanical uniaxial testing of the valve leaflets. RESULTS Among the Melody(®) valves, the incidence of transverse fractures was significantly higher in traumatized samples compared with the control group (P<0.05), whereas the incidence and depth of transverse fractures were not statistically different between the four conditions for bovine and porcine pericardial leaflets. No significant modification of the mechanical behaviour of in vitro traumatized Melody(®) valvular leaflets was observed. Bovine and porcine pericardia became more elastic and less resilient after balloon expansion and post-dilatation (conditions III and IV), with a significant decrease in elastic modulus and stress at rupture. CONCLUSION Valved stent implantation procedural steps induced histological lesions on Melody(®) valve leaflets. Conversely, bovine and porcine pericardial valved stents were not histologically altered by in vitro manipulations, although their mechanical properties were significantly modified. These data could explain some of the long-term complications observed with these substitutes.

Abstract
Advanced surgical repair procedures have resulted in the increased survival rate to adulthood of patients with CHD. The resulting new chronic conditions population is greater than one million in the United States of America and >1.2 million in Europe. This review describes the risks and effects of infective endocarditis - a systemic infectious process with high morbidity and mortality - on this population and examines the evidence to determine whether greater patient education on recognition of symptoms and preventative measures is warranted. The literature search included the terms "infective endocarditis" and "adult congenital heart disease". Search refinement, the addition of articles cited by included articles, as well as addition of supporting articles, resulted in utilisation of 24 articles. Infective endocarditis, defined by the modified Duke Criteria, occurs at a significantly higher rate in the CHD population due to congenitally or surgically altered cardiac anatomies and placement of prosthetic valves. This literature review returned no studies in the past five years assessing knowledge of the definition, recognition of symptoms, and preventative measures of infective endocarditis in the adult CHD population. Existing data are more than 15 years old and show significant knowledge deficits. Studies have consistently shown the need for improved CHD patient knowledge with regard to infective endocarditis, and there is no recent evidence that these knowledge deficits have decreased. It is important to address and decrease knowledge deficits in order to improve patient outcomes and decrease healthcare utilisation and costs.
