Project description:ObjectivesTo compare patient-reported outcome measures of minimally invasive (MI) to sternotomy (ST) mitral valve repair.MethodsWe included all patients undergoing isolated mitral valve surgery via either a right mini-thoracotomy (MI) or ST over a 36-month period. Patients were asked to complete a modified Composite Physical Function questionnaire. Intraoperative and postoperative outcomes, and patient-reported outcome measures were compared between 2 propensity-matched groups (n = 47/group), assessing 3 domains: 'Recovery Time', 'Postoperative Pain' (at day 2 and 1, 3, 6 and 12 weeks) and 'Treatment Satisfaction'. Composite scores for each domain were subsequently constructed and multivariable analysis was used to determine whether surgical approach was associated with domain scores.ResultsThe response rate was 79%. There was no mortality in either group. In the matched groups, operative times were longer in the MI group (P < 0.001), but postoperative outcomes were similar. Composite scores for Recovery Time [ST 51.7 (31.8-62.1) vs MI 61.7 (43.1-73.9), P = 0.03] and Pain [ST 65.7 (40.1-83.1) vs MI 79.1 (65.5-89.5), P = 0.02] significantly favoured the MI group. Scores in the Treatment Satisfaction domain were high for both surgical approaches [ST 100 (82.5-100) vs MI 100 (95.0-100), P = 0.15]. The strongest independent predictor of both faster recovery parameter estimate 12.0 [95% confidence interval (CI) 5.7-18.3, P < 0.001] and less pain parameter estimate 7.6 (95% CI 0.7-14.5, P = 0.03) was MI surgery.ConclusionsMI surgery was associated with faster recovery and less pain; treatment satisfaction and safety profiles were similar.

Project description:ObjectivesAlthough clinical experience with transcatheter mitral valve interventions is rapidly increasing, there is still a lack of evidence regarding surgical treatment options for the management of recurrent mitral regurgitation (MR). This study provides guidance for a minimally invasive surgical approach following failed transcatheter mitral valve repair, which is based on the underlying mitral valve (MV) pathology and the type of intervention.MethodsA total of 46 patients who underwent minimally invasive MV surgery due to recurrent or residual MR after transcatheter edge-to-edge repair or direct interventional annuloplasty between October 2014 and March 2021 were included.ResultsThe median age of the patients was 78 [interquartile range, 71-82] years and the EuroSCORE II was 4.41 [interquartile range, 2.66-6.55]. At the index procedure, edge-to-edge repair had been performed in 45 (97.8%) patients and direct annuloplasty in 1 patient. All patients with functional MR at the index procedure (n = 36) underwent MV replacement. Of the patients with degenerative MR (n = 10), 5 patients were eligible for MV repair after removal of the MitraClip. The 1-year survival following surgical treatment was 81.3% and 75.0% in patients with functional and degenerative MR, respectively. No residual MR greater than mild during follow-up was observed in patients who underwent MV repair.ConclusionsMinimally invasive surgery following failed transcatheter mitral valve repair is feasible and safe, with promising midterm survival. The surgical management should be tailored to the underlying valve pathology at the index procedure, the extent of damage of the MV leaflets and the type of previous intervention.

Project description:Objective: The aim was to assess the long-term outcomes, safety, and durability of total endoscopic mitral valve repair for Barlow mitral valve disease. Methods: A retrospective analysis of 98 patients undergoing minimal invasive total endoscopic mitral valve repair for Barlow mitral valve disease was conducted between May 2009 and December 2023. A non-resectional repair approach using artificial neochordae and/or ring annuloplasty was performed. Clinical and echocardiographic follow-ups were completed. Rates per patient-years with 95% confidence intervals (CI) for all time-to-event outcomes were calculated. Results: The mean age was 59 ± 12, and 43% were female. Minimally invasive mitral valve repair was successfully performed in all 98 patients with no conversions to sternotomy or mitral valve replacement. There was no mitral valve-related reoperation during the hospital stay. Procedural safety was as follows: no in-hospital mortality, no stroke, and no perioperative myocardial infarction. The mean follow-up was 4.1 ± 3.1 years. Survival at seven years was 87% (95% CI 63% to 96%). Freedom from myocardial infarction, stroke, and congestive heart failure was 89% (95% CI 60% to 97%), 93% (95% CI 82% to 97%), and 100%, respectively. Recurrent mitral valve insufficiency at Grade ≥ 2 was diagnosed in n = 4 (4.1%) of cases. Conclusions: Minimally invasive mitral valve repair using a non-resectional technique for Barlow disease can be performed with a low complication rate. The total endoscopic approach is safe in the long term, with minimal risk of reoperation and recurrent mitral valve insufficiency.

Project description:There is considerable interest and demand in the application of minimally invasive techniques in cardiac surgery driven by multiple factors including patient cosmesis and satisfaction, reduction of surgical trauma and the development of specialized instrumentation that allows these procedures to be performed safely. Minimally invasive mitral valve surgery (MIMVS) has been conducted for more than 25 years and has been shown to offer multiple benefits including better cosmetic results, enhanced post-operative recovery, improved patient satisfaction and most importantly, equivalent clinical outcomes with regards to quality and safety when compared to the standard sternotomy approach. MIMVS may be particularly beneficial in certain subgroups of patients, for example patients undergoing redo mitral valve surgery. In this article, we discuss patient selection criteria for MIMVS, the merits and drawbacks of MIMVS relative to conventional sternotomy approaches, and detail procedural aspects including anaesthetic management, intraoperative technique, and important considerations in myocardial protection and cardiopulmonary bypass (CPB). When considering developing a MIMVS programme, as for any new technique, a team approach to the introduction of the programme is essential. Although it is clear that patient selection is important, particularly early in a surgical programme, with experience complex repairs can be performed through a minimally invasive approach with excellent outcomes.

Project description:Pseudoaneurysm of the mitral-aortic intervalvular body is a rare condition, which has been reported as a result of endocarditis, chest trauma or cardiac surgery. We describe here the first case after minimally invasive mitral valve repair. Such a complication may be overlooked in the early postoperative echocardiographic study and may lead to fistula formation, compression of adjacent structures, infection, or rupture. Both computed tomography and echocardiography provide a detailed anatomy of the pseudoaneurysm and its communication with the left ventricular outflow tract.

Project description:ObjectiveThe use of transcatheter mitral valve repair (TMVr) devices is increasing in elderly and high-risk patients. However, the increasing number of patients with recurrent mitral regurgitation (MR) has confronted surgeons with the issue of how to explant the devices and whether the mitral valve should be repaired or replaced. The aim of the study is to summarize our clinical experience with the explantation of different TMVr devices and to provide alternative surgical techniques that can be performed in different clinical scenarios.MethodsA simulator system including a dummy valve representing native valves was used to create video documentation and to develop alternative surgical methods for clip explantation. Moreover, the clip explantation techniques were shown in 2 patients undergoing minimally-invasive mitral valve repair after a failed TMVr.ResultsAlternative explantation techniques were described for each TMVr device; 2 techniques for MitraClip and 3 techniques for PASCAL (Precision Transcatheter Valve Repair System), which may be adjusted for each individual according to the underlying valve pathology and the degree of device encapsulation. The patients were discharged without residual MR and remained MR free at the follow-up.ConclusionsTranscatheter edge-to-edge repair devices can be surgically explanted without damaging the MV leaflets. Removal of each device may require a different technique tailored to the degree of device encapsulation and valve pathology. Increasing experience may facilitate repair in patients with recurrent MR after TMVr.

Project description:Mitral valve disease is common in the United States and around the world, and if left untreated, increases cardiovascular morbidity and mortality. Mitral valve repair is technically more demanding than mitral valve replacement. Mitral valve repair should be considered the first line of treatment for mitral regurgitation in younger patients, mitral valve prolapse, annular dilatation, and with structural damage to the valve. Several minimally invasive percutaneous treatment options for mitral valve repair are available that are not restricted to conventional surgical approaches, and may be better received by patients. A useful classification system of these approaches proposed by Chiam and Ruiz is based on anatomic targets and device action upon the leaflets, annulus, chordae, and left ventricle. Future directions of minimally invasive techniques will include improving the safety profile through patient selection and risk stratification, improvement of current imaging and techniques, and multidisciplinary education.
