CLINICAL AND COLOR DOPPLER ECHOCARDIOGRAPHIC CORELATION OF SEVERITY OF MITRAL REGURGITATION

Abstract :

Corvisart in 1808 was the first to recognise mitral regurgitation, subsequently in the nineteenth and early twentieth centuries, it was the most frequently diagnosed valve lesion, and the presence of an apical systolic murmur was said to portend a grave outlook. MR can be detected in <3% in children but its incidence increases with age by 20 – 40% in adults and reaches 80% by the age of 80years. The early twentieth century English cardiologists, with improved diagnostic capabilities, began to diagnose mitral regurgitation with increased confidence. However, they tended to attribute the cardiac failure more to myocardial disease and dysfunction than to mechanical effects of mitral regurgitation. When in 1948, mitral valve surgery became possible, mitral regurgitation was seen in better perspective but it was not until the mid 1950s with the advent of left heart catheterisation and cineangiography that a totally accurate diagnosis of Mitral Regurgitation was achieved. Advances in surgical technique and valve substitutes play an important role in the management of patients with severe chronic mitral regurgitation, achieving both symptomatic improvement and modification of the natural history. Controversy still surrounds the exact timing of surgery for patients with varying degrees of chronic mitral regurgitation. The present study was undertaken to assess the clinical and 2 dimensional colour doppler echocardiographic severity of mitral regurgitation and assess the value of the various physical signs in diagnosing severe mitral regurgitation
