BACKGROUND: Transcatheter mitral valve repair (TMVR) has been shown to have acute effects on mitral valve geometry in patients with functional mitral regurgitation (FMR). This study investigates the impact of MitraClip(®) therapy-induced annular remodeling on clinical outcome and mitral regurgitation in heart failure patients. METHODS: TMVR was performed successfully in 45 patients with FMR. In this study, mitral valve datasets were obtained before and directly after MitraClip(®) implantation using three-dimensional (3D) transesophageal echocardiography, and were analyzed offline retrospectively using dedicated 3D reconstruction software...

AIMS: To test the feasibility of trans-catheter mitral valve implantation of the NaviGate device in acute and chronic preclinical models. METHODS AND RESULTS: We evaluated the NaviGate valved stent implantation in the mitral position in an acute swine model (n=24, ≤ 5 days) through three different approaches: trans-atrial, trans-apical, and trans-septal, and in a chronic swine model (n=12, >10 days) through a trans-atrial approach. The NaviGate implantation procedures were successful in 83% of the acute model studies (n=20) and 83% of the chronic model studies (n=10)...

We describe the case of a 57-year-old man who had severe mitral valve stenosis and regurgitation without significant annular calcification. He was not a candidate for surgical valve replacement or repair because of his substantial comorbid conditions, overall frailty, and elevated surgical risk. He underwent successful transcatheter mitral valve replacement of his native mitral valve with compassionate, off-label use of an Edwards Sapien 3 valve. A search of the literature produced no other cases like ours, which represents a further evolution of the transcatheter valve implantation concept...

We describe an improvised technique during open surgery of inserting a transcatheter heart valve in the mitral position under very challenging circumstances. This is the first described use of the "extended collar" technique, which allowed implantation of a transcatheter heart valve in severe mitral valve annular calcification, into which a surgical valve could not safely be implanted. We believe that this technique is reproducible and may be helpful to other surgeons when faced with similar difficult circumstances...

OBJECTIVES: This study is the first report of 2 cases of HighLife (HighLife, Paris, France) implantation in humans. BACKGROUND: Transcatheter mitral valve implantation represents a promising approach to treating mitral regurgitation in patients at increased risk of perioperative mortality. The HighLife transcatheter mitral valve is a 2-component system. The valve is implanted in the mitral position and is anchored by interacting and then reaching an equilibrium position with a previously positioned subannular implant...

BACKGROUND: Severe mitral regurgitation is associated with impaired prognosis if left untreated. Using the devices currently available, transcatheter mitral valve repair (TMVr) remains challenging in complex anatomical situations. We report the procedural and 30-day results of the first-in-man study of the Edwards PASCAL TMVr system. METHODS: In this multicentre, prospective, observational, first-in-man study, we collected data from seven tertiary care hospitals in five countries that had a compassionate use programme in which patients underwent transcatheter mitral valve repair using the Edwards PASCAL TMVr system...

Echocardiography is the cornerstone in the diagnosis of any valvular heart disease. The accurate diagnosis of aortic stenosis, the left ventricle function and the other heart valves evaluation are currently done by ultrasound alone. Prosthetic valve choice and dimensions prior to implantation can be done solely by proper use of echocardiography. The emergence of new methods to cure aortic stenosis such as trans-catheter aortic valve replacement (TAVR) emphasized the diagnostic value of cardiac ultrasound. The usefulness of echocardiography in TAVR can be divided in the baseline assessment (common to patients treated by conventional surgery), intra-procedural guidance of valve deployment and post-procedural follow-up...

The case is reported of a successful transcatheter implantation of an Edwards SAPIEN 3 valve (29 mm) into a failing tricuspid bioprosthesis (Sorin Pericarbon, 31 mm). The procedure was performed in a 69-year-old woman with post-rheumatic mitral and tricuspid valve disease. Multiple previous cardiac surgeries precluded the use of another surgical approach. A large, organized, two-piece thrombus in the enlarged right atrium was not considered an absolute contraindication to the procedure. The SAPIEN 3 valve was implanted under general anesthesia, via a femoral venous access, under three-dimensional transesophageal echocardiography guidance...

REVIEW

Valve thrombosis can occur in mechanical prosthetic valves and is increasingly recognised in transcatheter and surgically implanted bioprosthetic valves. The risk of thrombosis of mechanical valves is higher in the mitral position compared with aortic position and in older generation valves (ball and cage valves). There is a wide spectrum of presentation from the asymptomatic patient to those with embolic complications or cardiogenic shock. A combination of transthoracic and transesophageal echocardiography is required to assess the haemodynamic effect of thrombosis (valve gradients and area), leaflet motion and thrombus size...

Severe aortic valve stenosis (AVS) and mitral valve regurgitation (MVR) often coexist. Although a fully percutaneous treatment for the two conditions, by means of transcatheter aortic valve implantation (TAVI) followed by MitraClip, can be appealing in selected high-risk candidates, critical and strategical reasoning should be applied. In a 3-year period we have developed a single-centre experience of 14 patients who were managed with a staged percutaneous approach to treat severe AVS and MVR. The average interval from TAVI to MitraClip repair was 101 ± 12 days...

BACKGROUND: Transcatheter mitral valve implantation (TMVI) is still in its infancy and is mainly limited to valve-in-valve or valve-in-ring implantations. We present the early experience with TMVI for severe calcified native MV stenosis. METHODS: Between January 2014 and June 2015, 6 of 11 patients screened (mean age, 77.4 ± 6.3 years; 66% men) with severe native mitral valve (MV) stenosis (mean gradient [Pmean], 11.1 ± 2.1 mm Hg; mean effective orifice area [EOA], 0...

Heart failure has a high prevalence in the general population. Morbidity and mortality of heart failure patients remain high, despite improvements in drug therapy, implantable cardioverter-defibrillators and cardiac resynchronisation therapy. New transcatheter implantable devices have been developed to improve the treatment of heart failure. There has been a rapid development of minimally invasive or transcatheter devices used in the treatment of heart failure associated with aortic and mitral valve disease and these devices are being incorporated into routine clinical practice at a fast rate...

Background: Mitral valve regurgitation (MR), present in up to 74% of the patients with severe aortic stenosis (AS), can be a negative prognostic factor when moderate or severe. The outcome of MR after percutaneous transcatheter aortic valve implantation (TAVI) and predictors associated with that outcome have not been well established in the literature. Objective: To assess the outcome of primary MR in patients submitted to TAVI and to identify associated factors...

A 79-year-old woman with severe mitral annular calcification was scheduled for mitral valve replacement. A SAPIEN 3 valve was implanted in mitral position using an open surgical approach. Immediately after cardiopulmonary bypass, bleeding from an unidentified source was encountered. Cardiopulmonary bypass was emergently resumed and a laceration of the left ventricular apex due to the valve delivery system was detected. Risk factors specific to the open surgical approach include a decompressed ventricle, decreased annulus to apical distance, and the absence of continuous fluoroscopic and echocardiographic imaging...

OBJECTIVES: Transcatheter aortic valve implantation (TAVI) has been implemented into the care of elderly patients suffering from severe symptomatic aortic stenosis. However, data on long-term follow-up are sparse and predictors of long-term mortality need to be evaluated to better select patients. Therefore, we aimed to analyse predictors of 5-year mortality after TAVI. METHODS: We analysed data from the German Transcatheter Aortic Valve Interventions-Registry. Each of the 27 participating hospitals agreed to include all consecutive TAVI patients at their institution...
