Staphylococcus lugdunensis (S. lugdunensis) is a coagulase negative staphylococcus (CoNS) that can cause destructive infective endocarditis. S. lugdunensis, unlike other CoNS, should be considered to be a pathogen. We report the first case of S. lugdunensis endocarditis causing ventricular septal defect and destruction of the aortic and mitral valves. A 53-year-old male with morbid obesity and COPD presented with intermittent fever and progressive shortness of breath for 2 weeks. Chest examination showed bilateral basal crepitations, and a grade 2 systolic murmur along the right sternal border...

Primary cardiac tumors are a rare occurrence with myxomas accounting for about half of the benign tumors. Once diagnosed, surgical resection is the standard of care. Our case describes a female in her 50s who underwent a myxoma resection under cardiopulmonary bypass via biatrial approach. Intraoperatively, the thin septal crux between the wall of the aorta and mitral valve was damaged during resection, requiring stem cell tissue matrix for repair. The patient also developed severe mitral regurgitation suggesting infarct to the left coronary system during resection, subsequently receiving a mechanical mitral valve and a saphenous vein bypass graft...

BACKGROUND: Recurrent mitral regurgitation after mitral valve repair is common, occurring in nearly 50% of patients within 10 years of surgery. Durability of repair is partly related to stress distribution over the mitral leaflets. We hypothesized that repair with neochords (NCs) results in lower stress than leaflet resection (LR). MATERIALS AND METHODS: Magnetic resonance imaging and 3D echocardiography were performed before surgical repair of P2 prolapse in a single patient...

BACKGROUND: It is believed that most of thrombi form in the left atrial appendage (LAA)before they emboli. Different surgical and percutaneouse approaches were suggested to manage the LAA. In this study we are evaluating the safety of clipping the LAA via minithoractotomy approach. METHOD: All consecutive patients who had minimally invasive mitral valve surgery with concomitant LAA clipping between December 2012 and February 2014 were included in the study. LAA exclusion was performed using AtriClip® LAA Exclusion System (Cincinnati, Ohio, AtriCure®)...

A 52-year-old woman was admitted to our hospital for acute right hemi-paresis, left homonymous hemianopia, and fever. Magnetic resonance imaging of the brain showed multiple cerebral infarctions and transesophageal echocardiography (TEE) revealed a vegetation on the posterior leaflet of her mitral valve. Mitral valve repair was performed under a diagnosis of infective endocarditis (IE). Further multiple cerebral infarctions occurred on the 11th postoperative day, resulting in left hemiplegia and dysarthria...

Surgical treatment for mitral valve disease has evolved and remains a rapidly expanding field. Minimally invasive mitral valve repair (MI-MVR) is a well-known alternative to conventional sternotomy mitral valve repair (cMVR). However, controversy as to the efficacy of MI-MVR persists, hindering the adoption and potential benefits of this less invasive approach. Areas covered: In this review, we provide an updated summary evaluation of the latest evidence, including observational studies, clinical trials and meta-analyses, regarding MI-MVR in comparison to cMVR...

Thrombosis is a life threatening complications of prosthetic mitral valves and is associated with high morbidity and mortality. Even in presence of systemic anticoagulation prosthetic valve thrombosis has an incidence of 0.5% to 8%. Recurrent prosthetic valve thrombosis and the resulting thrombotic occlusion require re-establishment of blood flow across the valve. While surgical repair is considered the classic first line treatment option for prosthetic valve thrombosis, intravenous thrombolysis has emerged as an acceptable alternative for the first episode of prosthetic valve thrombosis...

BACKGROUND: -Mitral valve (MV) repair is preferred over replacement in clinical guidelines and is an important determinant of the indication for surgery in degenerative mitral regurgitation (MR). Yet, the level of evidence supporting current recommendations is low, and recent data cast doubts on its validity in the current era. Accordingly, the aim of the present study was to analyze very long-term outcome after MV repair and replacement for degenerative MR with a flail leaflet. METHODS: -MIDA is a multicenter registry enrolling patients with degenerative MR with a flail leaflet in 6 tertiary European and US centers...

We have modified the mitral repair technique in infants and small children by using autologous pericardial strips to treat mitral regurgitation resulting from a dilated mitral annulus. Our results demonstrate that this technique maintains stability and flexibility of the mitral annulus and decreases the risk of mitral stenosis.

PURPOSE OF REVIEW: This review summarizes the evidence describing functional mitral stenosis (MS) following surgical mitral valve repair. RECENT FINDINGS: Functional MS is an evolving concept and has been implicated in the repair of functional and organic mitral regurgitation. Following repair of functional mitral regurgitation, an elevation in peak transmitral gradient and pulmonary artery pressure has been observed under physiologic stress. These changes have been associated with worse functional status early after restrictive annuloplasty...

Significant mitral regurgitation (MR) is thought to decrease after left ventricular assist device (LVAD) implantation, and therefore repair of mitral valve is not indicated in current practice. However, residual moderate and severe MR leads to pulmonary artery pressure increase, thereby resulting in right ventricular (RV) dysfunction during follow-up. We examined the impact of residual MR on systolic function of the right ventricle by echocardiography after LVAD implantation. This study included 90 patients (mean age: 51...
