We have noted that the impedance cardiographic waveform of patients with mitral regurgitation may show typical abnormalities not found in other forms of cardiac disease, either valvular or congenital. In order to investigate this we reviewed the impedance cardiograms of all our patients who had also undergone cardiac catheterisation, and selected two groups both of which were inclusive and comp...
BACKGROUND Ischemic mitral regurgitation is associated with increased mortality and morbidity. For surgical patients with moderate regurgitation, the benefits of adding mitral-valve repair to coronary-artery bypass grafting (CABG) are uncertain. METHODS We randomly assigned 301 patients with moderate ischemic mitral regurgitation to CABG alone or CABG plus mitral-valve repair (combined proced...
The percutaneous edge-to-edge repair of mitral regurgitation with a MitraClip device has been recently approved in Europe. The results of the randomized EVEREST II study showed a favourable safety profile of the technique. However, the efficacy in terms of regurgitation reduction in a population with predominantly degenerative mitral disease was inferior as compared to the results of convention...
ventricular dyssynchrony on dynamic mitral regurgitation in patients with heart failure due to coronary artery disease. Am J Cardiol 2005; 96:1304–1307. 10. Breithardt OA, Sinha AM, Schwammenthal E, Bidaoui N, Markus KU, Franke A, Stellbrink C. Acute effects of cardiac resynchronization therapy on functional mitral regurgitation in advanced systolic heart failure. J Am Coll Cardiol 2003;41:765–...
INTRODUCTION In cases of mitral regurgitation, the severity of the regurgitation is the major determinant of progression to left ventricular dilatation and dysfunction. Therefore, precise measurement of regurgitant volume in patients with mitral regurgitation is important for evaluating the progression of the disease which can then determine the optimal time for surgical repair or replacement. ...
BACKGROUND Although chronic mitral regurgitation results in adverse left ventricular remodeling, its effect on the mitral valve leaflets per se is unknown. In a chronic ovine model, we tested whether isolated mitral regurgitation alone was sufficient to remodel the anterior mitral leaflet. METHODS AND RESULTS Twenty-nine sheep were randomized to either control (CTRL, n=11) or experimental (HO...
BACKGROUND The aim of this article is to present a systematic review of publications regarding the role of exercise echocardiography in the evaluation of functional mitral regurgitation. METHODS The PubMed database was searched using the following combination of keywords: "mitral" and "regurgitation" and "exercise" and "echocardiography". Initially, a list of 152 articles published between 19...
This review deals with the functional anatomy of the six components of the mitral apparatus, namely, the left atrial wall, annulus, leaflets, chordae tendineae, papillary muscles, and left ventricular wall. Each component is considered individually, in the context of the apparatus as a whole, in relation to the mode of closure of the normal mitral valve, and in the light of many acquired and co...
We selected 40 patients with severe symptomatic rheumatic mitral stenosis for balloon valvotomy using the Inoue balloon technique. The patients' mean age was 31 +/- 14 years and there were 24 females and 16 males. The patients were selected according to the following echo/Doppler criteria; 1. Severe mitral stenosis, i. e. mitral valve area (MVA) less than 1.1 cm2; 2. pliable anterior mitral val...
A 37-year-old man with end-stage idiopathic dilated cardiomyopathy underwent an orthotopic heart transplant followed by a reoperation with mitral annuloplasty for severe mitral regurgitation. Shortly thereafter, he developed severe tricuspid regurgitation and severe recurrent mitral regurgitation due to annuloplasty ring dehiscence. The dehisced annuloplasty ring was refixated, followed by tric...
