Resection (triangular or quadrangular) is considered the gold standard for the treatment of posterior leaflet prolapse and loop implantation a more recent alternative. We aimed to compare the long-term outcomes of triangular or quadrangular resection vs loop implantation.
Glutaraldehyde-fixed autologous or bovine pericardial patches used for mitral valve leaflet reconstruction have been associated with late calcification. Fresh autologous pericardium (FAP) may be a durable alternative.
Left atrial (LA) enlargement has been previously identified as a predictor of mortality in patients with medically managed mitral regurgitation (MR) due to mitral valve prolapse (MVP). No study has specifically assessed the prognostic value of LA size in patients undergoing mitral valve repair (MVRp).
In certain pathologies, mitral valve repair is complicated by a paucity of tissue caused by fibrosis or destruction. Utilization of autologous pericardium for leaflet augmentation may be the only option to repair these valves. We present the midterm results of mitral valve leaflet augmentation with glutaraldehyde fixed autologous pericardium. 130 consecutive patients undergoing mitral valve repair with glutaraldehyde fixed pericardial augmentation of leaflets were followed up clinically and by echocardiogra...
Initial studies have suggested the familial clustering of mitral valve prolapse, but most of them were either community based among unselected individuals or applied non-specific diagnostic criteria. Therefore little is known about the familial distribution of mitral regurgitation in a referral-type population with a more severe mitral valve prolapse phenotype. The objective of this study was to evaluate the presence of familial mitral regurgitation in patients undergoing surgery for mitral valve prolapse, ...
Mitral valve disease becomes more prevalent as the population ages. As the number of percutaneous mitral valve interventions expands, obscure clinical scenarios may emerge and challenge conventional treatment algorithms. Strategies for dealing with complex repairs build on prior experience in mitral perivalvular leak repair. Cases using nitinol- and expanded polytetrafluoroethylene-based devices are used to treat mitral regurgitation in cases of focal mitral perforations and leaks between previously placed ...
Three-dimensional saddle-shaped annuloplasty rings have been shown to create a larger surface of leaflet coaptation in mitral valve repair (MVR) for functional mitral regurgitation (FMR) and degenerative mitral regurgitation (DMR) which may increase repair durability. For the first time, this study reports mid-term results after MVR for DMR and FMR using a rigid three-dimensional ring (Profile 3D, Medtronic).
The aim of the article is to discuss different therapeutic options for patients with severe mitral valve dysfunction because of mitral annular calcification (MAC), including mitral valve repair, conventional mitral valve replacement, percutaneous transcatheter mitral valve replacement (TMVR), and hybrid procedures.
Left ventricular outflow tract obstruction (LVOTO) can be caused by multiple factors. One of rare causes of LVOTO is preserved anterior mitral valve leaflet and chordal apparatus after mitral valve replacement. Here, we describe a case of a patient who presented with worsening chronic congestive heart failure secondary to LVOTO from systolic anterior motion of residual native anterior mitral leaflet. This was surgically corrected by excision of anterior leaflet and chordal apparatus through the aortic root.
Mitral valve (MV) repair is the procedure of choice to correct mitral regurgitation caused by degenerative MV disease, due to its well-documented superiority over MV replacement. Repair of the MV is feasible in more than 95% of such patients and restores valve function and preserve ventricular function. Surgeons choose from a wide variety of mitral repair techniques, with the ultimate procedure based upon the pathology and the particular surgeon's personal preference. As a result, there is considerable cont...
Functional mitral regurgitation (FMR) is a common finding among patients with heart failure (HF) and it is related to adverse events. Outcomes in patients undergoing transcatheter mitral valve repair (TMVR) are still a matter of debate. We performed a meta-analysis to assess mid- and long-term outcomes of patients with FMR treated with MitraClip® compared to medical management.
Porcine and pericardial valves exhibited similar freedom from structural valve deterioration after aortic valve replacement. Limited data exists regarding their durability at long-term follow-up in the mitral position.
Degenerative mitral valve (MV) regurgitation (MR) is associated with left ventricular (LV) dilatation. Surgical treatment of MR has been shown to favorably affect LV remodeling. We prospectively compared the long-term echocardiographic outcomes of LV remodeling following mini-mitral repair for simple versus complex MV disease.
Mitral valve repair (MVr) for severe, degenerative mitral regurgitation (MR) is the gold standard, as medical management carries poor prognosis. However, despite clear benefit of MVr, many eligible patients are untreated. This study investigated whether MVr restores patients to normal life expectancy, at any age of operation, by comparing long-term survival of post-MVr patients to the life expectancy of the general United States (U.S.) population.
Degenerative mitral valve (MV) disease causing mitral regurgitation (MR) is the most common organic valve pathology and is classified based on leaflet motion. MV repair is indicated as the preferred technique (Class I indication) when the results are expected to be durable. Therefore, a detailed and systematic evaluation of MV apparatus is pivotal in allowing the proper surgical planning, as well as the screening for trans catheter-based treatment when surgery is not indicated.
Determine the rates, reasons, predictors, and costs of 30-day readmissions following transcatheter mitral valve repair (TMVR) versus surgical mitral valve repair (SMVR) in the United States.
Surgery for secondary mitral regurgitation is still controversial, especially when the left ventricle is damaged. The Mitra Clip has been shown to be safe and effective for certain patient groups but does not offer superior control of mitral regurgitation compared with the surgery. If performed safely, the surgery can provide greater benefits over the long-term. The objective of this study was to retrospectively investigate the early and long-term results of mitral valve surgery for secondary mitral valve r...
Transcatheter mitral valve repair (TMVr) for the treatment of mitral regurgitation (MR) is a complex procedure that requires development of a unique skillset.
There is high demand for minimally invasive mitral valve repair; however, it is unclear whether the minimally invasive approach provides the same performance of conventional sternotomy in a context of complex mitral valve disease. Here, we compared outcomes of minimally invasive and sternotomy procedures for bileaflet and Barlow's mitral valve disease.
This video demonstrates aortic valve repair during ascending aneurysm replacement. A 71-year-old male has congestive heart failure, Grade 3 aortic insufficiency (AI), and a 5.4 cm ascending aneurysm. On testing, the non-coronary leaflet is prolapsing, the annulus is 27 mm, and the leaflets size to a 21-mm ring. The ring is sutured beneath the aortic valve annulus with 9 horizontal mattress sutures. The non-coronary leaflet is plicated, correcting the prolapse. A 28 mm Dacron tube graft is sutured to the sup...
Mitral valve prolapse (MVP) is a relatively common valvular heart disease and is known to have a benign course. However, a certain subtype of MVP has a pathologic prognosis and can be accompanied by malignant cardiac arrhythmia causing sudden cardiac arrest, which can be characterized by bileaflet mitral valvular thickening and prolapse and frequent premature ventricular ectopic activity upon electrocardiography. Herein, we present two patients with bileaflet mitral prolapse who survived aborted sudden card...
Pulmonary hypertension (pHTN) is associated with increased risk of mortality after mitral valve surgery for mitral regurgitation. However, its association with clinical outcomes in patients undergoing transcatheter mitral valve repair (TMVr) with a commercially available system (MitraClip) is unknown.
Concomitant use of tricuspid valve (TV) surgery and minimally invasive mitral valve (MV) repair is debatable due to a prolonged time of surgery with presumably elevated operative risk. Herein, we examined cardiopulmonary bypass times and 30-day mortality in patients who underwent MV repair with and without concomitant TV surgery.
