PURPOSE Data on MitraClip procedural safety and efficacy in the Netherlands are scarce. We aim to provide an overview of the Dutch MitraClip experience. METHODS We pooled anonymised demographic and procedural data of 1151 consecutive MitraClip patients, from 13 Dutch hospitals. Data was collected by product specialists in collaboration with local operators. Effect on mitral regurgitation was ...
A 56-year-old man presented with breathlessness and chest pain. Echocardiography revealed 14-mm septal hypertrophy, complete systolic anterior motion of the anterior mitral valve leaflet, severe central mitral regurgitation, and a left ventricular outflow tract gradient of 40 mm Hg increasing to 56 mm Hg on Valsalva. A diagnosis of hypertrophic cardiomyopathy was made. Despite medical therapy, ...
OBJECTIVE To compare the early and late outcomes of off-pump coronary artery bypass grafting and coronary artery bypass graft + mitral valve repair in elderly patients with moderate chronic ischemic mitral regurgitation. METHODS One hundred and fifty elderly (age > 70 years) patients with moderate chronic ischemic mitral regurgitation who underwent off-pump coronary artery bypass grafting (n=...
Background A full understanding of the geometry of the nonplanar saddle-shaped mitral annulus can provide valuable information regarding the pathophysiology of mitral regurgitation (MR). Aim of the work To investigate mitral annular geometric deformities using three-dimensional echocardiography among patients with ischemic coronary illness with and without mitral regurgitation. Methods Thre...
Transcatheter valve implantation is a novel interventional technique, which was developed as an alternative therapy for surgical aortic valve replacement in inoperable patients with severe aortic stenosis. Despite limited experience in using transcatheter valve implantation for mitral and aortic regurgitation, transapical transcatheter aortic valve implantation and valve-in-valve implantation ...
Intraprocedural imaging continues to evolve in parallel with advances in percutaneous mitral valve interventions. This didactic review uses several illustrations and rich intraprocedural videos to further describe and demonstrate the role of the most up-to-date echocardiographic and advanced imaging technologies in the patient selection and intraprocedural guidance of percutaneous mitral valve ...
The most common cardiac cause of massive hemoptysis is mitral stenosis. Mitral regurgitation is rarely complicated by massive hemoptysis. A 48-year-old man with no significant medical history was admitted to our hospital with hemoptysis and production of 500 mL of blood within 24 hours. A pan-systolic murmur was found on chest examination. A chest computed tomography showed airspace consolidati...
Redo Mitral Valve Surgery Via a Right Thoracotomy with Heart-Lung Machine: Presentation of Two Cases
The rate of redo surgeries are increasing on account of previously performed coronary artery bypass graft surgeries, aortic/ mitral valve replacement surgeries due to valve stenosis/ regurgitation, mitral valve repair for ischemic mitral regurgitation, the aging in the population, mechanical valve thrombosis and wearing out of the mechanical valves.Resternotomy, anterolateral right thoracotomy ...

T H E NORMAL FUNCTIOS OF THE MmRAL valve depends on the anatomic and functional integrity of the entire valwlar apparatus. Mitral regurgi ta t ion results when one of its components is anatomically deficient or functionally inadequate. Mitral regurgitation is uqually secondary to rheumatic involvement of the mitral cusp and its chordz tendinez. Damage to the papillary muscles (without affecting...
