To determine the value of transesophageal ultrasound in the assessment of cardiac valve prostheses, 14 patients with clinically suspected mitral prosthesis malfunction were studied by transthoracic and transesophageal two-dimensional imaging as well as by color Doppler flow velocity mapping (color Doppler). Patients underwent left ventricular angiography (n = 13), surgery (n =11), or both angio...

Left parasternal cardiograms were recorded at the fifth intercostal space in 30 patients with mitral regurgitation. Early systolic outward movements (E), late systolic outward movements (LOM), and the ratio of the LOM area to the total area occupied by the left parasternal cardiogram (LPC area) were examined. Thirteen patients had pure mitral regurgitation due to ruptured chordae tendineae (ten...

Ischemic mitral regurgitation (IMR) is a common complication of acute myocardial infarction (AMI). Current evidences suggest that revascularization of the culprit vessels with percutaneous coronary artery intervention (PCI) or coronary artery bypass grafting can be beneficial for relieving IMR. A 2.5-year follow-up data of a 61-year-old male patient with ST-segment elevation AMI complicated wit...

We report a case of blood cyst of the anterior mitral leaflet leading to severe mitral regurgitation and heart failure in a 70-year-old woman with no other factors that could explain the severe mitral regurgitation.

Acute mitral regurgitation (MR) was produced in 12 dogs by closed chest partial valvulectomy and the relative contributions of MR pressure gradient (MRG), the time for regurgitant flow (VSI), and the MR orifice area (MRA) to mitral regurgitant volume (MRV) assessed. Aortic and left atrial pressures, biplane left ventricular (LV) angiography, forward flow and mitral regurgitant flow (MRF) were m...

Instantaneous ascending aortic blood flow was recorded at operation in five patients with severe, pure mitral regurgitation, and in nine dogs in which mitral regurgitation was produced experimentally under controlled conditions. In both the patients and the experimental animals, the pattern of aortic flow was abnormal during mitral regurgitation: peak flow occurred early, the percentage of tota...

INTRODUCTION We sought to determine the effect of cardiac massage on a pre-existing regurgitant mitral valve during open-chest cardiopulmonary resuscitation (OCCPR) in an animal experiment. METHODS Our study included 29 dogs that were used as experimental models. We anesthetized them and inserted a transesophageal echocardiographic (TEE) probe. Then we performed a transverse thoracotomy, atte...

The long term results of mitral valve annuloplasty for pure mitral regurgitation are assessed. Thirty-three of the 100 patients (mean age 16 years) had acute rheumatic carditis at the time of operation. Three basic techniques were used: measured asymmetrical annuloplasty (Reed) in 37 patients, posterior plication annuloplasty in 56, Carpentier ring in seven. There were six early deaths, two of ...

Objective: Annuloplasty rings are used to treat ischemic mitral regurgitation (IMR), but their exact effects on 3-D geometry of the overall mitral valve complex during acute left ventricular (LV) ischemia remain unknown. Methods: Radiopaque markers were sutured to the mitral leaflet edges, annulus, papillary muscle tips, and ventricle in three groups of sheep. One group served as control (n 1⁄4...
