Project description:Background: Infective endocarditis (IE) following mitral valve edge-to-edge repair is a rare complication with high mortality. Case summary: A 91-year-old male patient was admitted to intensive care unit with sepsis due to urinary tract infection after insertion of a urinary catheter by the outpatient urologist. Two weeks ago, the patient was discharged from hospital after successful transcatheter edge-to-edge mitral valve repair (TEER) using a PASCAL Ace device. The initially withdrawn blood revealed repeatedly Proteus mirabilis bacteremia as causal for the sepsis due to urinary tract infection. An antibiotic regime with Ampicillin/Sulbactam was initiated and discontinued after 7 days. During the clinical course the patient again developed fever and blood cultures again revealed P. mirabilis. In transesophageal echocardiography (TOE), IE of the PASCAL Ace device was confirmed by a vegetation accompanied by a mild to moderate mitral regurgitation. While the patient was stable at this time and deemed not suitable for cardiac surgery, the endocarditis team made a decision toward a prolonged 6-week antibiotic regime with an antibiotic combination of Ampicillin 2 g qds and Ciprofloxacin 750 mg td. Due to posterior leaflet perforation severe mitral regurgitation developed while PASCAL Ace vegetations were significantly reduced by the antibiotic therapy. Therefore, the patient underwent successful endoscopic mitral valve replacement. Another 4 weeks of antibiotic treatment with Ampicillin 2 g qds followed before the patient was discharged. Discussion: P. mirabilis is able to form biofilms, resulting in a high risk for endocarditis following transcatheter mitral valve repair especially when device endothelization is incomplete. Endoscopic mitral valve replacement could serve as a bailout strategy in refractory Clip-endocarditis.

Project description:ObjectiveAlthough regurgitant mitral valves can be repaired through surgical or transcatheter approaches, contemporary comparative outcomes are limited with the impact of residual and recurrent mitral regurgitation (MR) on clinical outcomes being poorly defined. We hypothesized that moderate (2+) or greater residual or recurrent (RR) MR-regardless of type of repair-predicts worse clinical outcomes.MethodsOur institutional experience of 660 consecutive patients undergoing mitral valve repair (2015-2021) consisting of 393 surgical mitral valve repair (SMVr) and 267 transcatheter edge-to-edge mitral valve repair (TEER) was studied. The echocardiographic impact of RRMR (2+) following both SMVr and TEER on death and reintervention was evaluated.ResultsPatients averaged 67.8 ± 14.2 years (SMVr = 63.8 ± 13.3 vs 73.6 ± 13.6, P < .0001) and 62.1% were male. Baseline clinical and demographic data were vastly different between the 2 groups. Residual or recurrent 2+ or greater MR developed in 25% (n = 68) of patients who received TEER compared with 6% (n = 25) of SMVr (P < .0001). Reintervention (9.3% vs 2.4%, P = .002) and death (37.9% vs 10.4%, P < .0001) rates at 3-years were greater among the TEER group versus SMVr group. Given the heterogeneity in baseline characteristics and difference in survival, each cohort was analyzed separately, stratified by RRMR, using multivariable modeling to identify predictors of repeat reintervention and death. There were too few events of RRMR in the SMVr cohort for evaluation. For the TEER subgroups, we observed greater long-term mortality, but not reintervention among those with RRMR., Hypertension was the strongest predictor of death and obesity was for reintervention.ConclusionsPatients undergoing SMVr and TEER are vastly different with respect to baseline patient characteristics and clinical outcomes, with patients who undergo TEER being much greater risk with poorer prognosis. Moderate or greater RRMR predicted worse long-term survival but not reintervention among patients who received TEER. Given the difference in survival among patients with RRMR following TEER, care must be taken to ensure that patients entering clinical trials and receiving TEER should have a high probability of achieving mild or less MR as seen in contemporary surgical results.

Project description:Mitral valve repair is the ideal approach in managing mitral valve infective endocarditis for patients requiring surgery. However, viable repair is influenced by the extent of valve destruction and there can be technical challenges in reconstruction following debridement. Overall, data describing long-term outcomes following mitral repair of infective endocarditis are scarce. We, therefore, assessed the late outcomes of 101 consecutive patients who underwent mitral valve repair for IE at the University of Ottawa Heart Institute from 2001 to 2021. The 5- and 10-year survival rate was 80.8 ± 4.7% and 61.2 ± 9.2%, respectively. Among these 101 patients, 7 ultimately required mitral valve reoperation at a median of 5 years after their initial operation. These patients were of a mean age of 35.9 ± 7.3 years (range 22-44 years) at the time of their initial operation. The 5- and 10-year freedom from mitral valve reoperation was 93.6 ± 3.4% and 87.7 ± 5.2%, respectively. Overall, mitral valve repair can be an effective method for treating infective endocarditis with a favourable freedom from reoperation and mortality over the long term.

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:The use of transcatheter edge-to-edge mitral valve repair (TEER) in symptomatic patients with severe mitral regurgitation (MR) has dramatically increased over the last few years. Current guidelines consider TEER as a reasonable option in symptomatic patients with primary or chronic secondary severe MR with high or prohibitive surgical risk and favorable anatomy. However, several anatomical and morphological mitral features have restricted the use of this mini-invasive technique in its early experience. The latest fourth generation (G4) of the MitraClip system has been recently introduced and includes the possibility of independent leaflet grasping and 4 different sizes. This technical update offers the possibility of selecting and combining multiple devices for complex mitral valve anatomies and challenging procedures, which helps expand the applications of TEER. The present review describes the potential advantages and the help of the MitraClip G4 devices to overcome various anatomic and morphologic issues in challenging cases with complex primary and secondary MR procedures.

Project description:BackgroundThe PASCAL system is a novel device for edge-to-edge treatment of mitral regurgitation (MR). The aim of this study was to compare the safety and efficacy of the PASCAL to the MitraClip system in a highly selected group of patients with complex primary mitral regurgitation (PMR) defined as effective regurgitant orifice area (MR-EROA) ≥ 0.40 cm2, large flail gap (≥ 5 mm) or width (≥ 7 mm) or Barlow's disease.Methods38 patients with complex PMR undergoing mitral intervention using PASCAL (n = 22) or MitraClip (n = 16) were enrolled. Primary efficacy endpoints were procedural success and degree of residual MR at discharge. The rate of major adverse events (MAE) according to the Mitral Valve Academic Consortium (MVARC) criteria was chosen as the primary safety endpoint.ResultsPatient collectives did not differ relevantly regarding pertinent baseline parameters. Patients` median age was 83.0 [77.5-85.3] years (PASCAL) and 82.5 [76.5-86.5] years (MitraClip). MR-EROA at baseline was 0.70 [0.68-0.83] cm2 (PASCAL) and 0.70 [0.50-0.90] cm2 (MitraClip), respectively. 3D-echocardiographic morphometry of the mitral valve apparatus revealed no relevant differences between groups. Procedural success was achieved in 95.5% (PASCAL) and 87.5% (MitraClip), respectively. In 86.4% of the patients a residual MR grade ≤ 1 + was achieved with PASCAL whereas reduction to MR grade ≤ 1 + with MitraClip was achieved in 62.5%. Neither procedure time number of implanted devices, nor transmitral gradient differed significantly. No periprocedural MAE according to MVARC occured.ConclusionIn this highly selected patient group with complex PMR both systems exhibited equal procedural safety. MitraClip and PASCAL reduced qualitative and semi-quantitative parameters of MR to an at least comparable extent.

Project description:Mitral regurgitation (MR) is the most prevalent valvular heart disease and, when left untreated, results in reduced quality of life, heart failure, and increased mortality. Mitral valve transcatheter edge-to-edge repair (M-TEER) has matured considerably as a non-surgical treatment option since its commercial introduction in Europe in 2008. As a result of major device and interventional improvements, as well as the accumulation of experience by the interventional cardiologists, M-TEER has emerged as an important therapeutic strategy for patients with severe and symptomatic MR in the current European and American guidelines. Herein, we provide a comprehensive up-do-date overview of M-TEER. We define preprocedural patient evaluation and highlight key aspects for decision-making. We describe the currently available M-TEER systems and summarise the evidence for M-TEER in both primary mitral regurgitation (PMR) and secondary mitral regurgitation (SMR). In addition, we provide recommendations for device selection, intraprocedural imaging and guiding, M-TEER optimisation and management of recurrent MR. Finally, we provide information on major unsolved questions and "grey areas" in M-TEER.

Project description:Many patients affected with mitral valve regurgitation suffer from multiple comorbidities. The MitraClip device provides a safe means of transcatheter valve repair in patients with suitable mitral valve anatomy who are at prohibitive risk for surgery. We describe our early procedural outcomes and present a summary of the current state of MitraClip technology in the United States.We performed a retrospective chart review of initial high-risk or inoperable patients who underwent MitraClip placement at our institution after completion of the EVEREST II study. We examined the primary outcome of 30-day mortality, and secondary outcomes included extent of reduction of mitral regurgitation (MR), New York Heart Association (NYHA) functional class improvement, length of stay, and major complications.A total of 115 high-risk patients (mean Society of Thoracic Surgeons predicted risk of mortality 9.4%±6.1%) underwent the MitraClip procedure at our institution between March 2009 and April 2014. Co-morbidities including coronary artery disease (67.8%), pulmonary disease (39.1%) and previous cardiac surgery (44.3%) were common. The device was placed successfully in all patients with a 30-day mortality of 2.6%. All patients demonstrated 3+ or 4+ MR on preoperative imaging, and 80.7% of patients had trace or 1+ MR at hospital discharge. NYHA class improved substantially, with 79% of patients exhibiting class III or IV symptoms pre-procedure and 81% reporting class I or II symptoms at one month follow-up.The MitraClip procedure provides a safe alternative to surgical or medical management for high-risk patients with MR and suitable valve anatomy. A comprehensive heart team approach is essential, with surgeons providing critical assessment of patient suitability for surgery versus percutaneous therapy as well as performance of the valve procedure.

Project description:BackgroundTranscatheter edge-to-edge repair (TEER) of the mitral valve (MV) can be performed using the PASCAL or MitraClip devices. Few studies offer a head-to-head outcome comparison of these two devices.Material and methodsPubMed, EMBASE, Cochrane Library, Clinicaltrials.gov and WHO's International Clinical Trials Registry Platform, from 1 January 2000 until 1 March 2023, were searched. Study protocol details were registered in the International Prospective Register of Systematic Reviews (PROSPERO ID: CRD42023405400). Randomized Controlled Trials and observational studies reporting head-to-head clinical comparison of PASCAL and MitraClip devices were eligible for selection. Patients with severe functional or degenerative mitral regurgitation (MR) who had undergone TEER of the MV with either PASCAL or MitraClip devices were included in the meta-analysis. Data from six studies (five observational and one randomized clinical trial) were extracted and analyzed. The main outcomes were a reduction in MR to 2+ or less, improvement of New York Heart Association (NYHA) and 30-day all-cause mortality. Peri-procedural mortality, success rate and adverse events were also compared.ResultsData from 785 and 796 patients that underwent TEER using PASCAL and MitraClip, respectively, were analyzed. Thirty-day all-cause mortality (Risk ratio [RR] = 1.51, 95% CI 0.79-2.89), MR reduction to maximum 2+ (RR = 1.00, 95% CI 0.98-1.02) and NYHA improvement (RR = 0.98, 95% CI 0.84-1.15) were similar in both device groups. Both devices had high and similar success rates (96.9% and 96.7% for the PASCAL and MitraClip group, respectively, p value = 0.91). MR reduction to 1+ or less at discharge was similar in both device groups (RR = 1.06, 95% CI 0.95-1.19). Composite peri-procedural and in-hospital mortality was 0.64% and 1.66% in the PASCAL and MitraClip groups, respectively (p value = 0.094). Rates of peri-procedural cerebrovascular accidents were 0.26% in PASCAL and 1.01% in MitraClip (p value = 0.108).ConclusionsBoth PASCAL and MitraClip devices have high success and low complication rates for TEER of the MV. PASCAL was not inferior to MitraClip in reducing the MR level at discharge.
