We report the case of a patient with severe mitral regurgitation who was diagnosed with double-orifice mitral valve by preoperative transthoracic and transoesophageal echocardiography. During surgery, it was revealed that the mitral valve was divided into 2 orifices, anterolateral and posteromedial, by a fibrous bridging tissue that was supported by the chordae tendineae originating from an accessory middle papillary muscle. The posterior scallop of the anterolateral orifice was prolapsed due to chordal elongation...

Percutaneous mitral valve repair for symptomatic severe mitral regurgitation has rapidly evolved as a viable therapeutic option for high-surgical risk patients. Both randomized clinical studies as well as real world registry data have demonstrated significant improvement in severity of MR and clinical outcomes. In carefully selected patients with severely reduced left ventricular systolic function and severe symptomatic MR, Mitraclip therapy seems to show promise.

Severe mitral regurgitation (MR) confers an adverse prognosis, frequently with debilitating symptoms of heart failure. While open surgical correction has been the standard of care for decades, novel catheter-based technologies have emerged that are highly effective in the treatment of MR. These percutaneous technologies, which include methods for both repair as well as valve replacement, have the potential to address unmet clinical needs in patients with MR, and serve as a viable alternative to surgery.

Robotic and minimally invasive mitral valve (MV) procedures have been performed with increasing frequency over time. These alternatives offer similar efficacy to that achieved via standard median sternotomy, particularly in large volume centers, along with low perioperative morbidity and mortality rates. Moreover, patient acceptance is oftentimes increased due to less postoperative pain and shorter recovery times, as well as superior cosmetic results. However, these techniques are technically complex and associated with a significant learning curve...

Mitral regurgitation (MR) is the second most common valvular heart disease referred for corrective surgery. Diagnostic and management dilemmas are not uncommon when dealing with MR patients. Exercise testing plays an important role in sorting out some of these clinical challenges. In primary asymptomatic MR, exercise testing allows symptom assessment, confident link of symptoms to valve disease severity, safe deferral of surgery for the next 1-year in patients with preserved exercise capacity, insights into the mechanism of exercise-induced dyspnea and helps in individual risk stratification...

Mitral regurgitation (MR) is the one of the most frequent valvular heart diseases in the developed world, often requiring surgical correction. Degenerative MR is the most common type of non-ischemic, organic MR in the western world. Since no medical treatment has been shown to be effective in preventing the consequences of volume overload in asymptomatic degenerative MR, risk stratification is essential. Currently, this is achieved using clinical and precisely quantified echocardiographic parameters, with newer technologies like cardiac magnetic resonance gaining increasing prominence...

BACKGROUND: Although non-transplant surgical interventions for non-ischemic dilated cardiomyopathy (NIDCM) are relatively effective, their feasibility and limitations have not been fully elucidated. The aim of this study was to define the feasibility and limitations of mitral valve repair, with or without surgical ventricular reconstruction for patients with NIDCM in terms of postoperative low cardiac output syndrome (LOS). METHODS: Twenty non-transplant candidates (aged 57±13 years) with NIDCM and significant mitral regurgitation had undergone mitral valve repair combined with submitral procedures...

Bleeding after cardiac surgery or cardiovascular interventions is associated with worse patient outcome. Only very limited data are available on the subject of bleeding after percutaneous edge-to-edge mitral valve repair (PMVR). We performed a single center analysis including 347 consecutive patients who underwent PMVR. Bleeding was defined according to the Mitral Valve Academic Research Consortium (MVARC) end point definition. The incidence of MVARC bleeding was 21.6% (n = 75), whereas major MVARC bleeding (hemoglobin decrease ≥3 g/dl) occurred in 7...

In industrialized countries, the most common etiology of mitral regurgitation (MR) is degenerative mitral valve (MV) disease. The natural history of severe degenerative MR is poor. However, its appropriate and timely correction is associated with a life expectancy similar to that of the normal population. Surgical MV repair is the gold standard treatment. This review will focus on the most recent evidence with a specific emphasis on surgical indications, timing of treatment, contemporary surgical techniques, Heart Teams and Centers of Excellence...

Re-do mitral valve surgery is associated with high morbidity and mortality. In recent years a variety of percutaneous repair techniques of surgical failures have emerged as safe and effective treatment options for several post-surgical problems including bioprosthetic mitral valve failure, prosthetic regurgitation or stenosis following annuloplasty, and periprosthetic regurgitation. This review will cover the indications, techniques and outcomes of these novel percutaneous therapies.

OBJECTIVES: Mitral valve (MV) repairs have been performed in paediatric patients with congenital MV stenosis. However, congenital MV stenosis lesions are a heterogeneous group of lesions, and their repair remains challenging. METHODS: From March 1999 to September 2014, MV repair was performed in 22 patients with congenital MV stenosis. The median age was 10.3 months (ranging from 22 days to 9.1 years), and the mean body weight was 7.9 ± 4.0 kg at the time of the operation...

The cardiac catheterization laboratory is advancing medicine by performing procedures on patients who would usually require sternotomy and cardiopulmonary bypass. These procedures are done percutaneously, allowing them to be performed on patients considered inoperable. Patients have compromised cardiovascular function or advanced age. An anesthesiologist is essential for these procedures in case of hemodynamic compromise. Interventionalists are becoming more familiar with transcatheter aortic valve replacement and the device has become smaller, both contributing to less complications...
