We sought to present our institutional protocol to manage incomplete initial repair of degenerative mitral regurgitation and to evaluate its mid-term outcomes. Eight hundred and fifteen patients with degenerative mitral insufficiency undergoing mitral valve repair were investigated in this study. The initial repair attempt was incomplete in 48 patients, leaving a degree of residual regurgitation > mild, and an elevated transmitral gradient or systolic anterior motion (SAM). These patients were further treated with medication or mitral valve re-repair or replacement under reinstituted cardiopulmonary bypass...

BACKGROUND: Artificial chord implantation has become one of the most applied techniques for mitral valve repair (MVR). Many techniques have been described with the goal of optimizing neochord implantation. A new annuloplasty device designed to simplify the determination of appropriate neochord length has been recently introduced. We will describe our initial experience with this new device. METHODS: The semirigid device is equipped with removable loops on the posterior aspect of the ring...

BACKGROUND: There are few reports regarding factors related to late-onset of atrial fibrillation (Af) after mitral valve repair, which can compromise long-term outcome. We analyzed the risk factors for late Af after mitral valve repair. METHODS AND RESULTS: Between 2001 and 2015, 318 patients (214 males; median, 57.7 years) underwent mitral valve repair for degenerative mitral insufficiency (MI) without concomitant aortic valve disease in our institute. Patients with a history of paroxysmal or chronic Af preoperatively were excluded...

OBJECTIVE: Transmitral blood flow produces a vortex ring (quantified using vortex formation time [VFT]) that enhances the efficiency of left ventricular (LV) filling. VFT is attenuated in LV hypertrophy resulting from aortic valve stenosis (AS) versus normal LV geometry. Many patients with AS also have aortic insufficiency (AI). The authors tested the hypothesis that moderate AI falsely elevates VFT by partially inhibiting mitral leaflet opening in patients with AS. DESIGN: Observational study...

Mitral regurgitation (MR) is the most frequent valvular disease in industrialised countries. MR is classified as primary (mostly degenerative with valve prolapse) or secondary (mainly due to underlying ischemic heart disease resulting in deformation of the valve structure). Surgical repair represents the optimal treatment for severe primary MR, whereas the benefits of surgical correction of secondary MR are controversial. Over the past few years, transcatheter techniques have been developed to treat MR, such as the percutaneous edge-to-edge procedure (MitraClip)...

Degenerative mitral valve disease nowadays is the most common cause of mitral insufficiency in developed countries and is associated with high morbidity and mortality. In the last decades repairing the mitral valve has become the operation of choice for treatment of the mitral valve prolapse, enabling to improve the geometry and function of the left ventricle and long-term survival. Nevertheless, the problem of choice of method of management of severe mitral regurgitation in asymptomatic patients with degenerative mitral valve disease remains unsolved...

BACKGROUND: Severe mitral annular calcification causing degenerative mitral stenosis (DMS) is increasingly encountered in patients undergoing mitral and aortic valve interventions. However, its clinical profile and natural history and the factors affecting survival remain poorly characterized. The goal of this study was to characterize the factors affecting survival in patients with DMS. METHODS: An institutional echocardiographic database was searched for patients with DMS, defined as severe mitral annular calcification without commissural fusion and a mean transmitral diastolic gradient of ≥2 mm Hg...

Percutaneous valve repair with the MitraClip represents a new and promising therapeutic option for patients with severe mitral regurgitation (MR). Mitral valve prolapse and flail leaflet are two major causes of degenerative MR in patients who underwent the MitraClip procedure. Mitral annular calcification (MAC) is also a less-frequent cause of degenerative MR. Among patients with MAC, open surgical treatment or valvular replacement is the treatment of choice for severe MR. Herein we present a case with severe MR secondary to MAC in whom successful percutaneous valve repair was accomplished with the MitraClip system due to the high risk of open-heart surgery...

PURPOSE OF REVIEW: In recent years, great emphasis has been placed on reconstructive techniques for the surgical management of heart valve disease. In this review, we discuss recent data and current practice as it pertains to the subject of reconstructive valve surgery. RECENT FINDINGS: New techniques and an improved understanding of the mechanisms of aortic insufficiency have led to marked improvement in the early and late outcomes of aortic valve repair. While mitral valve repair is the established approach for the management of degenerative mitral valve disease, surgical technique continues to be refined, with valve reconstruction principles applied to increasingly challenging anatomy...

Chronic degenerative valve disease (CDVD) is the most common cardiac disease in dogs, usually resulting in mitral valve insufficiency (MVI). The goal of this study was to investigate the occurrence of MVI in clinically healthy Beagle populations. A total of 79 adult healthy Beagles (41 females and 38 males; age: 5.6 ± 2.7 years, range 1.4 to 11.7 years) were examined. The diagnosis of MVI was based on the detection of a systolic murmur heard above the mitral valve, and was confirmed by colour flow Doppler (CFD) echocardiography...

BACKGROUND: In patients with mitral regurgitation (MR), the effective regurgitant orifice area can be estimated by measuring the vena contracta area (VCA). We hypothesize that the VCA has characteristic temporal dynamics related to the underlying mechanism of functional mitral regurgitation (FMR) versus degenerative mitral valve disease (DMVD). METHODS: VCA measurements obtained by planimetry of the proximal jet from 3D transesophageal echocardiographic (TEE) color flow Doppler data sets were acquired in 42 cardiac surgical patients, including 22 with FMR and 20 with DMVD...

BACKGROUND: In rare cases, echo findings of degenerative valve disease is similar to valvular mass. CASE PRESENTATION: A 56-year-old woman was evaluated for palpitation. Echocardiography revealed an 8- mm mass on the anterior mitral leaflet with minimal mitral insufficiency. Resection of the valve tumor was attempted to prevent a possible embolism. However, the lesion was not a tumor, but an aneurysm-like bulge on the anterior leaflet without chorda elongation. Triangular resection and ring annuloplasty were performed...
