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.

Apical 4 chamber view LV EF in Biplan Simpson = 63% with a stroke volume 31 ml/m²
Apical 2 chamber view LV EF in Biplan Simpson = 63% with a stroke volume 31 ml/m².
Apical 3 chamber view Notice the severe calcification of the aortic valve
Apical 4 chamber view Colour Doppler flow. Normal mitral flow and mild aortic regurgitation are seen.
Mitral Pulsed Doppler flow evaluation suggesting delayed relaxation.
Severe alteration of LV longitudinal function.
Significant decrease in LV longitudinal function with a global longitudinal strain -14.9% despite a LV >EF 63%
Mean Pressure Gradient = 25 mm HgPeak max V = 3.3 m/sStroke volume = 28ml/m²
There is aortic stenosis with normal EF and mean gradient of 25 mm Hg. Both DTI and Deformation evaluation suggest impairment of longitudinal function . Could it be a low flow low gradient aortic stenosis case?
Back to the basics! This is the aortic Doppler flow obtained with the Pedoff probe from the right parasternal approach. Mean gradient is now 49 mm Hg
So the Low Flow Low gradient severe Ao Stenosis is existing. It’s a complicated entity and the treatment is still debated even if some patients would probably take advantage of the aortic valve replacement.
But, don’t forget the PEDOFF: In this case the mean Gradient is > 40 mm Hg so is clear it is a severe aortic stenosis. Move to aortic valve replacement without any hesitation!
