Since its discovery, the severity of severe aortic stenosis (SAS) with paradoxical low gradient is not well defined and has been the subject of contradictory publications. Determining the prognosis of this subgroup compared to moderate aortic stenosis (SAM) and the classic SAS with high gradient is decisive for the therapeutic management. Aims: Define the natural history of moderate aortic stenosis to compare it with the natural history of SAS with high gradient and SAS with paradoxical low gradient. Methods and results: 208 patients between January 2000 and December 2005 (122 men, age 73 ± 11 years) with SAM (aortic valve area (AVA) between 1, 0 cm and 1.5cm² and with preserved. LVEF were retrospectively included and followed up in 2016.Echocardiographic and clinical parameters were analyzed. Advanced age, previous stroke and atrial fibrillation were predictive of decreased survival. The survival of patients with SAS with paradoxical low gradient (40 mmHg or Jess) was intermediate to the survival of patients with SAM and SAS with high gradient (greater than 40 mmHg). Conclusions: The prognosis of SAM is better than the prognosis of SAS with paradoxical low gradient, and the prognosis of SAS with paradoxal low gradient is better than the prognosis of SAS with high gradient. The prognosis is worse in cases of advanced age, history of stroke, history of COPD or atrial fibrillation. The prognosis of SAS with paradoxical low gradient low gradient is intermediate and it could be an intermediate evolutionary stage between SAM and the classic SAS with high gradient. Depuis sa découverte, le degré de sévérité de la sténose aortique sévère (SAS) à bas gradient paradoxal n'est pas bien déterminé et a fait l'objet de publications contradictoires. La détermination du pronostic de ce sous-groupe par rapport à la sténose aortique modérée (SAM) et à la SAS classique à haut gradient est déterminante pour la prise en charge thérapeutique. Objectifs. Définir l'histoire naturelle de la sténose aortique modérée afin de la comparer à l'histoire naturelle de la SAS classique à haut gradient et à bas gradient paradoxal. Méthodes et résultats. 208 patients entre janvier 2000 et décembre 2005 (122 hommes, âge 73 ± 11 ans) avec SAM (aire valvulaire aortique (AVA) entre 1.0 cm 2 et 1.5c m 2) et avec fraction d'éjection du ventricule gauche (FEVG) préservée ont été inclus rétrospectivement et suivis jusque 2016.Les paramètres échographiques et cliniques ont été analysés. L'âge avancé, les antécédents d'AVC, les antécédents de BPCO et de fibrillation auriculaire étaient des facteurs prédictifs de survie diminuée. La survie des patients avec SAS à bas gradient paradoxal (40 mmHg ou moins) était intermédiaire à la survie des patients avec SAM et SAS classique à haut gradient (supérieur à 40 mmHg). Conclusions. La SAM est de meilleur pronostic que la SAS à bas gradient paradoxal, et cette dernière est de meilleur pronostic que la SAS à haut gradient. Le pronostic est moins bon en cas d'âge avancé, d'antécédent d'AVC, d'antécédent de BPCO ou de fibrillation auriculaire. Le pronostic de la SAS à bas gradient paradoxal étant intermédiaire, celle-ci pourrait être un stade d'évolution intermédiaire entre la SAM et la SAS classique à haut gradient.

Objective: This study aims at analyzing the long and short-term natural story of patients suffering from light to moderate aortic valve stenosis, taking into account the valve stenosis' level of severity as well as the surgical risk. (Euroscore logistics).Material and methods: The study population consists of 399 patients (average age of 74 years old), 179 of whom are women suffering from light to moderate aortic valve stenosis who were examined during between 06/ 12/2002 and 22/07/2003 at the UCL-Namur Univerisitary hospital center in Mont-Godinne.The data analysis covers clinical data as well as trans-thoracic echocardiography with a TTEl ( first echography) and/or a TTEz ( presurgical echocardiography or the lattest echochaphy found in the listing). The mean follow-up time of the population is 57 months. We assess three endpoints : total mortality, valve replacement and combined endpoint.Results: Among the 399 patients, 74 had the aortic valve replaced ( all prothesises), 6 benefited from a TAVI ( 1,5 %), and 3 other patients from a valve dilatation (0,8 %).During the first year, 40 patients

Aortic stenosis is one of the most common and serious valvular diseases in the elderly. Its prevalence increases with age and treatment is always surgical. This book provides a comprehensive overview of aortic stenosis diagnosis and treatment. Chapters address such topics as the use of computer tomography in assessing aortic stenosis, role of frozen allografts in aortic valve surgery, transcatheter aortic valve implantation (TAVI), the Ross procedure, and more.

Degenerative aortic valve disease is the most prominent cardiac valve disease in Western societies. This volume describes some of the more important issues and problems for this condition: its progressive character and the underlying mechanisms of this progression diagnostic difficulties 1) ascertainment of valvular origin of symptoms in elderly; 2) the challenge of the low output - low gradient syndrome; 3) moderate aortic valve calcification during CABG; 4) prediction of the rate of progression (who will need surgery on short term and who not).
