Ischemic mitral regurgitation is an important consequence of LV remodeling after myocardial infarction. Echocardiographic diagnosis and assessment of ischemic mitral regurgitation are critical to gauge its adverse effects on prognosis and to attempt to tailor rational treatment strategy. There is no single approach to the echocardiographic assessment of ischemic mitral regurgitation: standard e...
Background: Percutaneous Transeptal Mitral Commisurotomy (PTMC) has been used in treating mitral stenosis with variable success, its main complication being mitral incompetence. There is a need to define the subgroup of the patients who benefit mostly from the procedure. Methods: We studied 110 patients (age 17 to 60 years mean 33.2) with mitral stenosis. PTMC was performed though femoral vein....
BACKGROUND Ischemic mitral regurgitation (IMR) is a consequence of coronary artery disease and the main underlying mechanism is augmented leaflet tethering due to outward displacement of the papillary muscles. Although mitral annuloplasty combined with coronary revascularization is usually effective in the treatment of IMR, occasionally the regurgitation can persist or recur and this can affect...
Methods A group of patients with mitral regurgitation underwent electrocardiography, chest teleradiography, venous blood withdrawal, and transthoracic echocardiography. Based on an analysis of the echocardiographic variables, 62 patients had mild and moderate mitral regurgitation (GI) and 34 had severe mitral regurgitation (GII). The discriminating capacity of the BNP for detecting patients wit...
Accurate quantitation of mitral regurgitation offers a major clinical dilemma. The clinical clues depend largely on cardiac auscultation, the accuracy of which needs to be rigorously tested (1). Mitral regurgitation may not be associated with a clinically audible systolic murmur, and the auscultatory features of severity of regurgitation are generally based on increased volume of diastolic flow...
We report a patient with profound hypovolemia who developed dynamic left ventricular outflow tract obstruction and severe mitral regurgitation. Both the outflow tract obstruction and mitral regurgitation resolved with volume replacement. Unlike previous reports of dynamic left ventricular outflow obstruction and mitral regurgitation, the degree of mitral regurgitation was severe. Possible mecha...
Echocardiography was used to study left ventricular size and contraction in 90 patients with isolated mitral valve disease--47 patients with mitral stenosis, 26 with mixed mitral valve disease and 89 with mitral regurgitation. Left ventricular measurements included the end-diastolic internal dimension (LVIDd), mural thickness (PWTd), an index of circumferential myocardial contraction--fractiona...
The mean pressure drop across the mitral valve and atrioventricular pressure half-time were measured noninvasively by Doppler ultrasound in 40 normal subjects, in 17 patients with mitral regurgitation, 32 patients with mitral stenosis and 12 with combined stenosis and regurgitation. In normal subjects pressure half-times were 20--60 msec, in patients with isolated mitral regurgitation 35--80 ms...
Mrs B, a 49-year-old female, was referred to our institution for severe mitral regurgitation. Transthoracic echocardiography showed only a moderate organic mitral regurgitation, but a transient severe reversible functional mitral regurgitation was observed during transoesophageal echocardiography (TEE). Three-dimensional TEE clearly demonstrated the functional nature of the regurgitation with a...
INTRODUCTION Ischemic mitral regurgitation can be defined as moderate to severe mitral leak precipitated by acute myocardial infarction. Valve repair is now the procedure of choice, but some cases can pose difficult anatomy. This review will illustrate current techniques for repairing complex ischemic mitral regurgitation. METHODS Most patients with ischemic mitral regurgitation have predomin...
