Blending three repair techniques in a case of complex mitral valve endocarditis.

In a 39-year-old male with mitral valve endocarditis, after 6 weeks of intravenous antibiotics, echocardiography confirmed multiple vegetations on both leaflets, a flail posterior leaflet flail and contained perforation of the anterior leaflet in a windsock-like morphology. All vegetations, diseased and ruptured chords and the windsock-like contained rupture of the anterior leaflet were carefully resected via a right minithoracotomy and with femoral cannulation. Three repair techniques were blended to reconstruct the valve: (1) A large, infected portion of the prolapsing posterior leaflet was resected in a triangular fashion, and the edges were re-approximated using continuous 5-0 polypropylene sutures. (2) The anterior leaflet defect was repaired with a circular autologous pericardial patch that had been soaked in glutaraldehyde. (3) A set of artificial chords for P2 was created using CV-4 polytetrafluoroethylene sutures and adjusted under repeated saline inflation. A 38-mm Edwards Physio-I annuloplasty ring was implanted. The artificial chords were adjusted again after annuloplasty and then tied. Transoesophageal echocardiography (TEE) confirmed the absence of residual mitral regurgitation and systolic anterior motion and a mean pressure gradient of 3 mmHg. The patient was discharged after 5 days with a peripherally inserted central catheter to complete an additional 4 weeks of intravenous antibiotics and had an uneventful recovery.

Impact of valvular surgery according to frailty risk in patients with infective endocarditis.

BACKGROUND: Observational studies suggest that valvular surgery can reduce mortality in selected patients with infective endocarditis (IE). However, the benefit of this intervention according to frailty levels remains unclear. Our study aims to assess the effect of valvular surgery according to frailty status in this population. METHODS: We performed a retrospective study using the 2016-2019 National Inpatient Sample database. Adult patients with a primary diagnosis of IE were included. Frailty was assessed using the Hospital Frailty Risk Score. Inverse probability of treatment weighting (IPTW) was used to balance baseline differences between groups. RESULTS: A total of 53,275 patients with IE were included, with 18.3% underwent valvular surgery. The median age was 52 (34-68) years, with 41% females. Overall, 42.7% had low risk of frailty, 53.1% intermediate risk, and 4.2% high risk. After IPTW adjustment, in-hospital mortality was similar both for the entire cohort between valvular and non-valvular surgery groups (3.7% vs. 4.1%, p = .483), and low (1% vs. 0.9%, p = .952) or moderate (5.4% vs. 6%, p = .548) risk of frailty. However, patients at high risk of frailty had significantly lower in-hospital mortality in the valvular surgery group (4.6% vs. 13.9%, p = .016). Renal replacement therapy was similar between groups across frailty status. In contrast, surgery was associated with increased use of mechanical circulatory support and pacemaker implantation. CONCLUSIONS: Our findings suggest that there was no difference in survival between valve surgery and medical management in patients at low/intermediate frailty risk, but not for high-risk individuals.

To repair or to replace in mitral valve infective endocarditis? an updated meta-analysis.

BACKGROUND: Valve infective endocarditis (IE) is a potentially life-threatening condition that affects patients' livelihoods. Current surgical options in mitral valve IE include mitral valve repair (MVr) or replacement (MVR). While each procedure boasts its merits, doubt remains as to which type of surgery is superior. METHODS: We searched PubMed, Scopus, Web of Science, and Cochrane literature databases for studies comparing MVR and MVr in mitral valve IE. Any randomized controlled trial (RCT) or observational studies that compare MVR vs. MVr in mitral valve IE were eligible. Our dichotomous outcomes were extracted in the form of event and total, and risk and hazard ratio (RR)(HR) with 95% confidence interval (CI) and were pooled and calculated using RevMan 5.0. RESULTS: Our study included 23 studies with a total population of 11,802 patients. Compared to MVR, MVr had statistically significant lower risks of both early mortality with RR [0.44; 95% CI, 0.38-0.51; p < 0.001] and long-term follow-up mortality with HR [0.70; 95% CI, 0.58-0.85; p = 0.0004]. Moreover, MVr was associated with a statistically significant lower risk of IE recurrence with RR [0.43; 95% CI, 0.32-0.58; p < 0.001]; however, no statistically significant differences between both groups in terms of re-operations with RR [0.83; 95% CI, 0.41-1.67; p = 0.60]. CONCLUSION: Our results suggest that MVr was superior in terms of in-hospital mortality, long-term survival, and risk of recurrence without significance in valve reoperation. Therefore, MVr is appropriate as a primary treatment choice and should be considered whenever possible in most IE patients.

Impact of postoperative cerebral complications in acute infective endocarditis: a retrospective single-center study.

BACKGROUND: The treatment of patients with infective endocarditis (IE) who have preoperative cerebral complications remains less understood. Therefore, this study aimed to retrospectively evaluate the clinical outcomes of patients with acute IE based on preoperative intracranial findings. METHODS: Of 32 patients with acute IE treated at our hospital between August 2015 and March 2022, 31 patients of whom preoperative intracranial imaging evaluation was available were included in our analysis and compared with those with and without intracranial findings. We controlled the mean arterial blood pressure and activated clotting time (ACT) to prevent abnormally high perfusion pressures and ACTs during cardiopulmonary bypass (CPB). The preoperative background, and postoperative courses focusing on postoperative brain complications were reviewed. RESULTS: Among the 31 patients, 20 (65%) had preoperative imaging findings. The group with intracranial findings was significantly older, with more embolisms in other organs, positive intraoperative pathology findings, and longer CPB times. A new cerebral hemorrhage developed postoperatively in one patient without intracranial findings. There were no early deaths; two patients had recurrent infections in each group, and one died because of sepsis in the late phase in the group with intracranial findings. CONCLUSIONS: Positive intracranial findings indicated significantly active infectious conditions preoperatively but did not affect the postoperative course. Patients without preoperative cerebral complications can develop serious cerebral hemorrhage. Although meticulous examination of preoperative cerebral complications in all patients with IE is essential, a strategy should be adopted to prevent cerebral hemorrhage, even in patients without intracranial findings.

Management of embolic splenic abscess secondary to aortic valve endocarditis - case report and review of literature.

BACKGROUND: Splenic abscess is a serious complication associated with infective endocarditis. There is still contradicting evidence regarding the optimal treatment pathway including timing of valve intervention and the approach for managing splenic foci. CASE PRESENTATION: We present a case of a hybrid staged approach in which we successfully performed a laparoscopic splenectomy following percutaneous abscess drainage and a delayed aortic valve replacement. CONCLUSIONS: A multidisciplinary teamwork is fundamental in providing optimal care for patients with distant complications associated with infective endocarditis. Our hybrid approach seems safe and feasible.

Devastating fungal endocarditis involving ascending aorta in a patient with a history of aortic valve replacement: a case report.

BACKGROUND: Fungal endocarditis is a rare but serious condition associated with high mortality rates. Various predisposing factors contribute to its occurrence, such as underlying cardiac abnormalities, cardiac surgeries, prosthetic cardiac devices, and central venous catheters. Diagnosing fungal endocarditis, particularly Aspergillus, poses challenges, often complicated by negative blood cultures. CASE PRESENTATION: This report details a case of extensive ascending aorta involvement in Aspergillus endocarditis (AE) in a 24-year-old man with a history of bioprosthesis aortic valve replacement (AVR). Three months post-AVR, he presented with pericardial effusion and aortic rupture, leading to a redo biological valved conduit aortic root replacement (Bentall surgery). Despite the intervention, the tubular graft exhibited extensive Aspergillus involvement, resulting in graft disruption and significant peri-aortic infection. A second redo procedure involving aortic homograft root replacement was performed. Unfortunately, the patient succumbed two days after the surgery. CONCLUSION: A combined approach of medical and surgical therapies is recommended to manage fungal endocarditis. Despite efforts, the mortality rate associated with Aspergillus endocarditis remains unacceptably high, with no significant difference observed between combination therapy and antifungal treatment alone. Further research is essential to explore novel therapeutic strategies and improve outcomes for patients with this challenging condition.

Swiss Cheese Heart: A Tale of Multiple Valve Perforations.

Gerbode defect, an anomalous connection between the left ventricle and right atrium, is often congenital but can be acquired or iatrogenically formed. We present an exceedingly rare case of this defect associated with multiple valve perforation in an otherwise healthy patient with bicuspid aortic valve and endocarditis.

Sex differences and outcomes in surgical infective endocarditis.

BACKGROUND: Cardiac surgery for infective endocarditis (IE) is associated with significant hospital mortality, and female sex may be associated with worse outcomes. However, the impact of sex on the presenting characteristics, management, and outcomes of patients operated on for acute infective endocarditis (IE) has not been adequately studied. OBJECTIVES: The goal of our study was to analyse differences in management and outcome of IE between women and men who undergo surgery. METHODS: Clinical data of 717 patients undergoing cardiac surgery for IE between December 2005 and December 2019 were prospectively collected. Sex-related postoperative outcomes including in-hospital mortality were recorded. Univariable and multivariable analyses were performed to identify potential sex-related determinant of in-hospital mortality. RESULTS: In all, 532 male patients (74.2%) and 185 female patients (25.8%) underwent surgery for IE. At baseline, women had more frequent mitral regurgitation with 63 patients (34.1%) than men with 135 patients (25.4%) (P = 0.002). Female sex was associated with higher in-hospital mortality (23.2% versus 17.3%, P = 0.049). However, multivariable analysis revealed age (P < 0.01), antibiotics < 7 days before surgery (P = 0.01) and staphylococcal IE (P < 0.01) but not female sex (P = 0.99) as independent determinants of hospital mortality. CONCLUSIONS: In this study of patients operated-on for IE, female sex was associated with more severe manifestations of IE and significantly higher in-hospital mortality. However, after multivariable analysis, initial presentation, but not sex, seemed to determine clinical outcomes.

Paediatric aortic valve replacement using decellularized allografts: a multicentre update following 143 implantations and five-year mean follow-up.

OBJECTIVES: Decellularized aortic homografts (DAH) were introduced in 2008 as a further option for paediatric aortic valve replacement (AVR). METHODS: Prospective, multicentre follow-up of all paediatric patients receiving DAH for AVR in 8 European centres. RESULTS: A total of 143 DAH were implanted between February 2008 and February 2023 in 137 children (106 male, 74%) with a median age of 10.8 years (interquartile range 6.6-14.6). Eighty-four (59%) had undergone previous cardiac operations and 24 (17%) had undergone previous AVR. The median implanted DAH diameter was 21 mm (interquartile range 19-23). The median operation duration was 348 min (227-439) with a median cardiopulmonary bypass time of 212 min (171-257) and a median cross-clamp time of 135 min (113-164). After a median follow-up of 5.3 years (3.3-7.2, max. 15.2 years), the primary efficacy end-points peak gradient (median 14 mmHg, 9-28) and regurgitation (median 0.5, interquartile range 0-1, grade 0-3) showed good results but an increase over time. Freedom from death/explantation/endocarditis/bleeding/thromboembolism at 5 years were 97.8 ± 1.2/88.7 ± 3.3/99.1 ± 0.9/100 and 99.2 ± 0.8%, respectively. Freedom from death/explantation/endocarditis/bleeding/thromboembolism at 10 years were 96.3 ± 1.9/67.1 ± 8.0/93.6 ± 3.9/98.6 ± 1.4 and 86.9 ± 11.6%, respectively. In total, 21 DAH were explanted. Seven were replaced by a mechanical AVR, 1 Ross operation was performed and a re-do DAH was implanted in 13 patients with no redo mortality. The calculated expected adverse events were lower for DAH compared to cryopreserved homograft patients (mean age 8.4 years), and in the same range as for Ross patients (9.2 years) and mechanical AVR (13.0 years). CONCLUSIONS: This large-scale prospective analysis demonstrates excellent mid-term survival using DAH with adverse event rates comparable to paediatric Ross procedures.

Trends in epidemiology, surgical management, and prognosis of infective endocarditis during the XXI century in Spain: A population-based nationwide study.

BACKGROUND: Few population-based studies have evaluated the epidemiology of infective endocarditis (IE). Changes in population demographics and guidelines on IE may have affected both the incidence and outcomes of IE. Therefore, the aim of our study is to provide contemporary population-based epidemiological data of IE in Spain. METHODS: Retrospective nationwide observational study using data from the Spanish National Health System Discharge Database. We included all patients hospitalized with IE from January 2000 to December 2019. RESULTS: A total of 64,550 IE episodes were included. The incidence of IE rose from 5.25 cases/100,000 person-year in 2000 to 7.21 in 2019, with a 2% annual percentage change (95% CI 1.3-2.6). IE incidence was higher among those aged 85 or older (43.5 cases/100.000 person-years). Trends across the study period varied with sex and age. Patients with IE were progressively older (63.9 years in 2000-2004 to 70.0 in 2015-2019, p < 0.001) and had more frequent comorbidities and predispositions, including, previous valvular prosthesis (12.1% vs 20.9%, p < 0.001). After adjustment, a progressive reduction in mortality was noted including in 2015-2019 compared to 2010-2014 (adjusted odds ratio 0.93, 95% confident interval 0.88-0.99, p = 0.023)., which was associated with more frequent cardiac surgery in recent years (15.1% in 2010-2014 vs 19.9% in 2015-2019). CONCLUSIONS: In Spain, the incidence of IE has increased during the XXI century, with a more pronounced increase in elderly individuals. Adjusted-mortality decreased over the years, which could be related to a higher percentage of surgery. Our results highlight the changing epidemiology of IE.

How-I-Do-It: Aortic Annular Enlargement - Are the Nicks and Manouguian Obsolete?

The Y-incision aortic annular enlargement (AAE), first performed in August 2020, offers a safe and more effective alternative for management of a small aortic annulus/root without need for violation of the left ventricular outflow tract, mitral valve geometry, or left/right atria in both first-time aortic valve replacement (AVR) and reoperative AVR. In the first consecutive 119 patients with Y-incision AAE, the median age was 65 (59, 71), 67% female, 28% had previous cardiac surgery, and 2 cases had endocarditis. The preoperative mean gradient was 36 (30, 47), and the native aortic valve area was 0.9 (0.7, 1.0). After aortic annular enlargement, the median prosthesis size was 29 (27, 29) with 63% of patients having a size 29 or the largest sized valve. The median increment of annulus enlargement was 3 (3, 4) valve sizes. Postoperative complications included 1 operative mortality, 1 stroke exacerbation, and 2 pacemaker implantations (including one case of endocarditis with Gerbode fistula). There was no renal failure requiring permanent dialysis, mediastinitis, or reoperation for bleeding. Postoperative computed tomography aortogram showed the aortic root was enlarged from 27 (24, 30) to 40 (37, 42) mm without aortic pseudoaneurysm. The postoperative mean gradient was 6 (5, 9) mm Hg and valve area was 2.2 (1.8, 2.6) cm2 at 24 months. Mitral and tricuspid valve functions were significantly improved. This report describes the Y-incision technique with the most up-to-date modifications and short-term outcomes.

Five-year results from a prospective, single-arm European trial on decellularized allografts for aortic valve replacement-the ARISE Study and ARISE Registry Data.

OBJECTIVES: Decellularized aortic homografts (DAH) were introduced as a new option for aortic valve replacement for young patients. METHODS: A prospective, EU-funded, single-arm, multicentre study in 8 centres evaluating non-cryopreserved DAH for aortic valve replacement. RESULTS: A total of 144 patients (99 male) were prospectively enrolled in the ARISE Trial between October 2015 and October 2018 with a median age of 30.4 years [interquartile range (IQR) 15.9-55.1]; 45% had undergone previous cardiac operations, with 19% having 2 or more previous procedures. The mean implanted DAH diameter was 22.6 mm (standard deviation 2.4). The median operation duration was 312 min (IQR 234-417), the median cardiopulmonary bypass time was 154 min (IQR 118-212) and the median cross-clamp time 121 min (IQR 93-150). No postoperative bypass grafting or renal replacement therapy were required. Two early deaths occurred, 1 due to a LCA thrombus on day 3 and 1 due ventricular arrhythmia 5 h postoperation. There were 3 late deaths, 1 death due to endocarditis 4 months postoperatively and 2 unrelated deaths after 5 and 7 years due to cancer and Morbus Wegener resulting in a total mortality of 3.47%. After a median follow-up of 5.9 years [IQR 5.1-6.4, mean 5.5 years. (standard deviation 1.3) max. 7.6 years], the primary efficacy end-points peak gradient with median 11.0 mmHg (IQR 7.8-17.6) and regurgitation of median 0.5 (IQR 0-0.5) of grade 0-3 were excellent. At 5 years, freedom from death/reoperation/endocarditis/bleeding/thromboembolism were 97.9%/93.5%/96.4%/99.2%/99.3%, respectively. CONCLUSIONS: The 5-year results of the prospective multicentre ARISE trial continue to show DAH to be safe for aortic valve replacement with excellent haemodynamics.

[Surgical Treatment with Pulsed Lavage Irrigation for Infective Endocarditis].

INTRODUCTION: Pulsed lavage irrigation (PLI) is a procedure used to wash contaminated soft tissues and prevent infection in orthopedic surgery. We applicated PLI for surgical treatment of infective endocarditis( IE). SUBJECTS AND METHODS: From January 2017 to June 2021, 6 cases underwent surgical treatment IE using PLI. We investigated an efficacy of PLI. RESULTS: Infected valves were mitral valve in 4 cases, aortic valve in 1 case, and aortic prosthetic valve in 1 case. The performed procedures were mitral valve plasty in 4 cases, aortic valve replacement in 1 case, and 1 removal of vegetation on the aortic prosthetic valve. No recurrence of IE or no deterioration of the native valve or the prosthetic valve was observed in follow-up periods. CONCLUSION: PLI was useful for surgical treatment of IE because of no recurrence of IE or no deterioration of native mitral valves or the aortic prosthetic valve.

Early Surgery for Infective Endocarditis Complicated With Neurologic Injury.

OBJECTIVES: To estimate the association between early surgery and the risk of mortality in patients with left-sided infective endocarditis in the context of stroke. DESIGN: Retrospective cohort study. SETTING: This study was a multiinstitution study based on the Chang Gung Research Database, which contains electronic medical records from 7 hospitals in northern and southern Taiwan; these include 2 medical centers, 2 regional hospitals, and 3 district hospitals. PARTICIPANTS: Patients with active left-sided infective endocarditis who underwent valve surgery between September 2002 and December 2018. INTERVENTIONS: The authors divided patients into 2 groups, with versus without preoperative neurologic complications, had undergone early (within 7 d) or later surgery, and with brain ischemia or hemorrhage. MEASUREMENTS AND MAIN RESULTS: Three hundred ninety-two patients with a median time from diagnosis to surgery of 6 days were included. No significant differences in postoperative stroke, in-hospital mortality, or follow-up outcomes were observed between the patients with and without neurologic complications. Among the patients with preoperative neurologic complications, patients who underwent early surgery had a lower 30-day postoperative mortality rate (13.1% v 25.8%; hazard ratio, 0.21; 95% CI 0.07-0.67). In the subgroup analysis of the comparison between brain ischemia and hemorrhage groups, there was no significant between-group difference in the in-hospital outcomes or outcomes after discharge. CONCLUSIONS: Early cardiac surgery may be associated with more favorable clinical outcomes in patients with preoperative neurologic complications. Thus, preoperative neurologic complications should not delay surgical interventions.

Conservative Versus Surgical Therapy in Patients With Infective Endocarditis and Surgical Indication-Meta-Analysis of Reconstructed Time-to-Event Data.

BACKGROUND: Infective endocarditis represents a life-threatening disease with high mortality rates. A fraction of patients receives exclusively conservative antibiotic treatment due to their comorbidities and high operative risk, despite fulfilling criteria for surgical therapy. The aim of the present study is to compare outcomes in patients with infective endocarditis and indication for surgical therapy in those who underwent or did not undergo valve surgery. METHODS AND RESULTS: Three databases were systematically assessed. A pooled analysis of Kaplan-Meier-derived reconstructed time-to-event data from studies with longer follow-up comparing conservative and surgical treatment was performed. A landmark analysis to further elucidate the effect of surgical intervention on mortality was carried out. Four studies with 3003 patients and median follow-up time of 7.6 months were included. Overall, patients with an indication for surgery who were surgically treated had a significantly lower risk of mortality compared with patients who received conservative treatment (hazard ratio [HR], 0.27 [95% CI, 0.24-0.31], P<0.001). The survival analysis in the first year showed superior survival for patients who underwent surgery when compared with those who did not at 1 month (87.6% versus 57.6%; HR, 0.31 [95% CI, 0.26-0.37], P<0.01), at 6 months (74.7% versus 34.6%) and at 12 months (73.3% versus 32.7%). CONCLUSIONS: Based on the findings of this study-level meta-analysis, patients with infective endocarditis and formal indication for surgical intervention who underwent surgery are associated with a lower risk of short- and long-term mortality when compared with conservative treatment.

Minimally invasive procedures for right side infective endocarditis: A targeted literature review.

INTRODUCTION: Right-side infective endocarditis (RSIE) is caused by microorganisms and develops into intracardiac and extracardiac complications with high in-hospital and 1-year mortality. Treatments involve antibiotic and surgical intervention. However, those presenting with extremes e.g. heart failure, or septic shock who are not ideal candidates for conventional medical therapy might benefit from minimally invasive procedures. OBJECTIVE: This review summarizes existing observational studies that reported minimally invasive procedures to debulk vegetation due to infective endocarditis either on valve or cardiac implantable electronic devices. METHODS: A targeted literature review was conducted to identify studies published in PubMed/MEDLINE, EMBASE, and Cochrane Central Database from January 1, 2015 to June 5, 2023. The efficacy and/or effectiveness of minimally invasive procedural interventions to debulk vegetation due to RSIE were summarized following PRISMA guidelines. RESULTS: A total of 11 studies with 208 RSIE patients were included. There were 9 studies that assessed the effectiveness of the AngioVac system and 2 assessed the Penumbra system. Overall procedure success rate was 87.9%. Among 8 studies that reported index hospitalization, 4 studies reported no death, while the other 4 studies reported 10 deaths. CONCLUSIONS: This study demonstrates that multiple systems can provide minimally invasive procedure options for patients with RSIE with high procedural success. However, there are mixed results regarding complications and mortality rates. Further large cohort studies or randomized clinical trials are warranted to assess and/or compare the efficacy and safety of these systems.

Suppressive antibiotic therapy for infectious endocarditis.

OBJECTIVES: Suppressive antibiotic therapy (SAT) is a long-term antibiotic strategy at times applied when an indicated surgical management of infective endocarditis (IE) is not possible. Our aim was to describe the characteristics and outcomes of patients having received SAT for IE. METHODS: We conducted a retrospective, observational study at Strasbourg University Hospital, France between January 2020 and May 2023. We reviewed all medical files taken into consideration at weekly meetings of the local Multidisciplinary Endocarditis Team (MET) during the study period. We included patients having received SAT following the MET evaluation. The primary endpoint was all-cause mortality at most recent follow-up. Secondary endpoints included all-cause mortality at 3 and 6 months, infection relapse, and tolerance issues attributed to SAT. RESULTS: The MET considered 251 patients during the study time, among whom 22 (9 %) had received SAT. Mean age was 77.2 ± 12.3 years. Patients were highly comorbid with a mean Charlson index score of 6.6 ± 2.5. Main indication for SAT was surgery indicated but not performed or an infected device not removed (20/22). Fourteen patients had prosthetic valve IE, including 9 TAVIs. Six patients had IE affecting cardiac implantable electronic devices. Staphylococcus aureus and enterococci were the main bacteria involved (6/22 each). Median follow-up time was 249 days (IQR 95-457 days). Mortality at most recent follow-up was 23 % (5/22). Three patients (14 %) presented tolerance issues attributed to SAT, and two patients suffered late infectious relapse. CONCLUSION: Mortality at most recent follow-up was low and tolerance issues were rare for patients under SAT, which might be a palliative approach to consider when optimal surgery or device removal is not possible.

Surgical repair and replacement for native mitral valve infective endocarditis.

AIMS: The clinical benefits of mitral valve repair over replacement in the setting of mitral infective endocarditis are not clearly established. METHODS: Data of patients who underwent cardiac surgery for infective endocarditis over a 20-year period (2001-2021) at two cardiac centres were reviewed. Among them, 282 patients underwent native mitral valve surgery and were included in the study. Nearest-neighbour propensity-score matching was performed to account for differences in patients' profile between the repair and replacement subgroups. RESULTS: Mitral valve replacement was performed in 186 patients, while in 96 cases patients underwent mitral valve repair. Propensity match analysis provided 89 well matched pairs. Mean age was 60 ±â€Š15 years; 75% of the patients were male. Mitral valve replacement was more commonly performed in patients with involvement of both mitral leaflets, commissure(s) and mitral annulus. Patients with lesion(s) limited to P2 segment formed the majority of the cases undergoing mitral valve repair. There was no difference in terms of microbiological findings. In-hospital mortality was 7% with no difference between the repair and the replacement cohorts. Survival probabilities at 1, 5 and 10 years were 88%, 72% and 68%, respectively after mitral repair, and 88%, 78% and 63%, respectively after mitral replacement (log-rank P  = 0.94). CONCLUSIONS: Mitral valve repair was more commonly performed in patients with isolated single leaflet involvement and provided good early and 10-year outcomes. Patients with annular disruption, lesion(s) on both leaflets and commissure(s) were successfully served on early and mid-term course by mitral valve replacement.
