Our mission is to become a worldwide reference for education in the field for all professionals involved in the process to disseminate knowledge & skills of Acute Cardiovascular Care.
Our mission is to promote excellence in clinical diagnosis, research, technical development, and education in cardiovascular imaging in Europe.
Our mission is to promote excellence in research, practice, education and policy in cardiovascular health, primary and secondary prevention.
Our mission is to reduce the burden of cardiovascular disease through percutaneous cardiovascular interventions.
Improving the quality of life and reducing sudden cardiac death by limiting the impact of heart rhythm disturbances.
Our mission is to improve quality of life and longevity, through better prevention, diagnosis and treatment of heart failure, including the establishment of networks for its management, education and research.
The ESC Working Groups' goal is to stimulate and disseminate scientific knowledge in different fields of cardiology.
The ESC Councils' goal is to share knowledge among medical professionals practising in specific cardiology domains.
Mitral regurgitation is visible on cine images as an area of signal loss extending from the mitral valve into left atrium. The signal loss can be graded in a similar way to x-ray angiography or color-Doppler echocardiography:
This semi-quantitative method has been validated although its reproducibility is quite unsatisfactory and it is affected by the same intrinsic limitations as color-Doppler echocardiography and invasive angiography.
A combination of left ventricular volumetric quantification and phase-contrast imaging performed at level of ascending aorta, however, allows accurate and reproducible assessment of mitral regurgitation. In the presence of regurgitation, the difference in cardiac output between the left ventricle and ascending aorta yields the regurgitation volume. Regurgitation fraction is calculated by normalizing the regurgitation volume to the left ventricular stroke volume. Use of regurgitation fraction should be recommended as this parameter has the advantage to be relatively insensitive to concomitant other valve abnormalities. Regurgitation fraction limits for mitral and aortic regurgitations have been estimated by using cardiac MRI: mild ≤ 15%; moderate 16-25%; moderate-severe 26-48%; severe > 48%.
