2 Reconstruction of the Aortic Valve and Root - A Practical Approach - I declare for the last 3 years and the subsequent 12 month the following conflicts of interests: Section I: Support for Research Activities - grant of the DEGUM - no other financial research support Section II: Support for Educational Activities - MIFO, GE Healthcare, Astra Zeneca, Servier, Novartis, Berlin-Chemie, Pfizer, Cardiac Dimension, Abbott, Bayer, Kelcon Section III: Honorarium for Promotional Activities - none Section IV: Personal Financial Interests in Vommercial Activities - none IB1; 2A11 Member of the German Society of Cardiology, The German Society of Ultrasound, the German Society of Internal Medicine and the European Society of Cardiology/Cardiovascular Imaging Councillor of the EACVI Board Universitätsmedizin Leipzig (2016) - Hagendorff -Aortic Valve Regurgitation and Aortic Aneurysm - Epidemiology and Guidelines 2
3 The Euro Heart Survey on Valvular Heart Disease included prospectively 5001 patients. according to Iung et al., EurHeartJ 2003:24, Universitätsmedizin Leipzig (2016) - Hagendorff -Aortic Valve Regurgitation and Aortic Aneurysm - Epidemiology and Guidelines 3
4 Incidence in epidemiology is a measure of the probability of occurrence of a given medical condition in a population within a specified period of time. The cumulative incidence is the number of new cases within a specified time period divided by the size of the population initially at risk, e.g cases per persons per year. Prevalence is the proportion of cases in the population at a given time usually expressed as a fraction, as a percentage or as the number of cases per or people.

8 And the grading of the severity of VHD seems to be a real problem. Thus, the Euro Heart Survey contains interesting data on characteristics and management of patients with valvular heart disease, but no epidemiological data concerning incidence and prevalence of VHD.

11 according to Singh et al., Am J Cardiol 1999;83: This study sought to assess the prevalence and clinical determinants of mitral (MR), tricuspid (TR), and aortic (AR) regurgitation in a population-based cohort. Color Doppler echocardiography was performed in 1696 men and 1893 women (aged years) attending a routine examination at the Framingham Study.

16 Frequency or prevalence of aortic regurgitation is about 0.5% of the adult population. Universitätsmedizin Leipzig (2016) - Hagendorff -Aortic Valve Regurgitation and Aortic Aneurysm - Epidemiology and Guidelines 16
17 About 5% for both, AS and AR according to Nkomo et al., Lancet 2006;368: Universitätsmedizin Leipzig (2016) - Hagendorff -Aortic Valve Regurgitation and Aortic Aneurysm - Epidemiology and Guidelines 17

19 Survival in pts with severe AR depends on symptons and NYHA classification Universitätsmedizin Leipzig (2016) - Hagendorff -Aortic Valve Regurgitation and Aortic Aneurysm - Epidemiology and Guidelines 19
20 according to Dujardin et al., Ciculation 1999; 99: Survival is higher, if LVS-diameter/BSA is < 25mm/m 2 If AR is severe, event rate is high. Universitätsmedizin Leipzig (2016) - Hagendorff -Aortic Valve Regurgitation and Aortic Aneurysm - Epidemiology and Guidelines 20

22 Universitätsmedizin Leipzig (2016) - Hagendorff -Aortic Valve Regurgitation and Aortic Aneurysm - Epidemiology and Guidelines 22
23 Reduced LVEF in chronic severe AR is a significant factor of bad prognosis. However, reduced LVEF is not a contraindication to consider AVR. according to Chaliki et al., Circulation 2002;106: Universitätsmedizin Leipzig (2016) - Hagendorff -Aortic Valve Regurgitation and Aortic Aneurysm - Epidemiology and Guidelines 23
24 ARincidence: 0.8% Combined AR- and MR- Incidence: 0.5% AR is associated with aortic root diameter- according to Reid et al.; Am J Cardiol 2007;99: Universitätsmedizin Leipzig (2016) - Hagendorff -Aortic Valve Regurgitation and Aortic Aneurysm - Epidemiology and Guidelines 24
25 Universitätsmedizin Leipzig (2016) - Hagendorff -Aortic Valve Regurgitation and Aortic Aneurysm - Epidemiology and Guidelines 25
26 according to Vahanian et al., Eur Heart J 2012; 33: Symptoms Endsystolic LV-dimension > 50mm LV-ejection fraction < 50% Diastolic LV-Dimension > 70mm Significant progression of symptoms Significant deterioration of indices Universitätsmedizin Leipzig (2016) - Hagendorff -Aortic Valve Regurgitation and Aortic Aneurysm - Epidemiology and Guidelines 26
27 according to Vahanian et al., Eur Heart J 2012; 33: Conclusion: Grading of the AR severity is the crucial point. Universitätsmedizin Leipzig (2016) - Hagendorff -Aortic Valve Regurgitation and Aortic Aneurysm - Epidemiology and Guidelines 27
28 La Place law: T = ½ P r / d T = wall tension P = transmural pressure r = radius d = wall thickness T r The increase in r compensates volume overload. T r Because wall thickness (also = wall stress) increases, wall tension will be normalized.

29 pressure [mmhg] Aortic Regurgitation and Aortic Aneurysm Pathophysiology of Aortic Regurgitation End-systolic pressure volume relationship (ESPVR) describes the maximal pressure that can be developed by the ventricle at any given LV volume. ESPVR Stroke volume End-diastolic pressure volume relationship (EDPVR) describes the passive filling curve for the ventricle and thus the passive properties of the myocardium Stroke volume Normal conditions Chronic aortic regurgitation volume [ml] EDPVR Universitätsmedizin Leipzig (2016) - Hagendorff -Aortic Valve Regurgitation and Aortic Aneurysm - Epidemiology and Guidelines 29
30 Chronic Aortic regurgitation Progressive myocardial dysfunction is due to: 1. Impaired myocardial function With an increase of functionally abnormal myocytes and fibrosis 2. Decreased coronary flow reserve Secondary to excentric left ventricular hypertrophy and increased wall stress Patients become symptomatic at different levels of left ventricular dysfunction. But: how to be sure that symptoms are really related to aortic regurgitation? Thus, grading of the aortic regurgitation is the crucial point.

66 Summary: AR - Epidemiology and Guidelines Epidemiological data about incidence and prevalence of aortic regurgitation are rare. The prevalence and incidence of aortic regurgitation is age-dependent. The qualitative evidence of aortic regurgitation is about 5% of the total population. The prevalence of severe aortic regurgitation is about 0.5% of the total population. In the elderly > 75 years it is about 5%. Indications for surgery in patients with aortic regurgitation are primarily symptoms, enlargement of LV-dimensions and impairment of LV-function as well as progression of symptoms and deterioration of LV-indices. Impaired LV-function in pts with AR is a significant risk factor of surgical therapy. Symptoms have to be identified in relation to the valvular defect. Thus, the grading of the severity of AR is the crucial factor for the therapeutical decision making. Universitätsmedizin Leipzig (2016) - Hagendorff -Aortic Valve Regurgitation and Aortic Aneurysm - Epidemiology and Guidelines 66
67 Summary: TAA - Epidemiology and Guidelines Epidemiological data about incidence and prevalence of thoracic aortic aneurysms (TAA) are rare. The incidence of aortic regurgitation is about 10 per per year. There are various shapes of aortic root and thoracic aortic aneurysms, which have been classified due to different mechanisms. Aortic root aneurysm is related to calcified aortic valves, left ventricular wall motion abnormalities and male gender. The normal values for the aortic root and the proximal thoracic aorta are recently published in the NORRE study. Indications for surgery in patients with TAA are aortic diameter > 45mm in pts with Marfan syndrome, > 50mm in BAV pts with risk factors and > 55mm in allother patients. In BAV pts cusp fusion morphology alters outflow patterns and consecutive aortopathy due to different wall shear-stress TAA has to be monitored to detect aortic enlargement and to prevent aortic dissection.
