A patient presented with symptoms of decompensated heart failure 2 months after percutaneous mitral valve (MV) repair. Echocardiography demonstrated impaired left ventricular function with elevated MV pressure gradients and pulmonary pressures during rapid atrial fibrillation. Heart rate control was achieved by implantation of a biventricular pacemaker with subsequent His-bundle ablation because atrial fibrillation was refractory to medical treatment. During biventricular pacing at different rates (50-110 b...

BACKGROUND: This report studies the early and medium-term clinical and echocardiographic outcomes of the Alfieri edge-to-edge mitral valve repair, as adjunctive therapy, to prevent and treat systolic anterior motion (SAM) at the time of septal myectomy (SM) for left ventricular outflow tract obstruction in hypertrophic cardiomyopathy. METHODS: From 2009-2015, 11 consecutive patients had a trans-atrial Alfieri repair, to prevent (n = 7) or treat (n = 4) SAM at the time of SM...

Mitral valve percutaneous edge-to-edge repair (PEtER) is a viable solution in high-risk patients with severe symptomatic mitral regurgitation. However, the generated double-orifice configuration poses challenges for the evaluation of the hemodynamic performance of the mitral valve and may alter flow patterns in the left ventricle (LV) during diastole. This in vitro study aims to evaluate the hemodynamic modifications following a simulated PEtER. A custom-made mitral valve was developed, and two configurations were tested: (i) a single-orifice valve with mitral regurgitation and (ii) a double-orifice mitral valve configuration following PEtER...

The development of less invasive approaches for mitral valve repair remains an important objective, particularly in patients with multiple comorbidities. We describe a novel method to affix a mitral valve annuloplasty ring in a minimally invasive manner. A delivery apparatus for an annuloplasty fastener system was designed. Two channels were created, one for advancing the annuloplasty ring, and another to accommodate the fastener applicator. Custom designed fasteners, either with a helical-shaped screw or a strap-shaped tack structure, were tested...

BACKGROUND: Total aortic arch replacement (TOTAL) is a complicated operation and has traditionally required deep hypothermic circulatory arrest. In this study, the impact of moderate hypothermic circulatory arrest (MHCA) and antegrade cerebral perfusion (ACP) for TOTAL were examined. METHODS: The ARCH International aortic database was queried and 3,265 patients undergoing TOTAL using ACP were identified. Patients were divided into groups based on lowest cooling temperature: MHCA (20° to 28°C) or deep hypothermia (DHCA) (12° to 20°C)...

BACKGROUND: The optimal management of chronic severe primary degenerative mitral regurgitation (MR) is to repair the valve but identification of the optimal timing of surgery remains challenging. Current guidelines suggest 'watchful waiting' until the onset of symptoms or left ventricular (LV) dysfunction but these have been challenged as promoting 'rescue surgery'. Better predictors are required to inform decision-making in relation to the necessity and timing of surgery. Chronic volume overload is a stimulus for adverse adaptive LV remodelling...

Functional mitral regurgitation (MR;FMR) is the most common type of MR and its development is associated with increased morbidity and mortality. Leaflet tethering with apical shift of the papillary muscle due to adverse left ventricular remodeling and loss of normal leaflet coaptation is the principal mechanism of FMR. Echocardiography plays a central role in the assessment of the FMR. The development of 3D echocardiography has allowed for assessment of the geometric changes of mitral valve morphology and spatial relationship with the left ventricle that accompanies FMR...

BACKGROUND: Occurrence of severe mitral valve (MV) regurgitation (MR) is an independent negative predictor of mortality in patients with severe systolic heart failure (HF). This study examines clinical effects and cardiac reverse remodelling in patients with severe systolic HF receiving percutaneous mitral valve repair (PMVR) using MitraClip in comparison to patients receiving optimal medical therapy only. METHODS: Between 2010 and 2014, 86 patients (Society of Thoracic Surgeons score: 10...

Aims: We hypothesized that the absence of a decrease in minimal left ventricular (LV) pressure during exercise would be associated with impaired LV apical back rotation during exercise. Methods and results: A total of 21 patients (59 ± 10 years) underwent invasive LV pressure measurements and simultaneous echocardiography at rest and during submaximal supine bicycle exercise. Patients were classified according to the changes in minimal LV pressure from rest to maximal exercise (Δminimal LVP); Group 1 (n = 8) had a decrease in minimal LV pressure with exercise, whereas Group 2 (n = 13) had an increase in minimal LV pressure...

A new controversy is raising in cardiovascular surgery, whether or not the new generation transcatheter valves used for valve implantation are superior to surgical techniques used for traditional valve replacement. If such a debate is far from being an issue for mitral valve treatment, where minimal invasive, (robotic or video-assisted) mitral valve repair has become the gold standard for mitral valve treatment while transcatheter mitral valve solutions are lagging behind(1-4), there are many voices stating that the future of aortic valve treatment will mainly be transcatheter(5)...

BACKGROUND: Significant mitral regurgitation (MR) may reduce a pressure gradient of aortic stenosis (AS) by decreasing forward stroke volume. The study objective was to evaluate whether significant MR can cause inconsistency when assessing the severity of AS. METHODS: Among 5,355 patients diagnosed with AS from 2000 to 2015, 68 were retrospectively found to have concomitant significant (moderate or greater) MR and normal left ventricular ejection fractions in normal sinus rhythm (AS with MR)...

A semi-rigid complete ring including a chordal sizing system has been introduced with the aim of standardizing neochordae implantation. Instructions for use of this ring suggest to pass the neochordae through the free margin of mitral leaflets. We introduce a modification of this technique in the presence of myxomatous leaflets.

Transcatheter valve procedures are wide-spreading techniques for the treatment of heart valves pathologies. In case of implantation failure, the transcatheter device often needs to be removed. This procedure, which can alter the biological structure integrity, can limit the option available for the subsequent traditional surgery. One of the most popular devices for transcatheter mitral valve repair is the MitraClip system. In this work, we describe 2 different techniques for the surgical removal of MitraClip...

INTRODUCTION: When clinicians think about Staphylococcus aureus bacteria, what comes to the mind of most is the dreaded methicillin-resistant form. However, clinicians should not forget the methicillin-susceptible type, which is just as virulent. CASE PRESENTATION: The authors present the case of a 20-year-old woman who was admitted with septic shock and multi-organ failure and was found to have disseminated methicillin-susceptible Staphylococcus aureus (MSSA) infection...

We present the surgical implantation in mitral position of the Edwards Sapien 3 valve for prosthetic valve endocarditis in a severely ill child after multiple valve replacements. The procedure was safely performed and provided adequate hemodynamic results in the short term. This report highlights the excellent potential of Sapien 3 valve for the treatment of mitral valve disease in children with a mitral valve annulus of appropriate size. Of note, the use of the Sapien 3 valve should be considered when a bioprosthesis is required at the time of valve re-replacement...
