چکیده
9) Background. Severe left ventricular (LV) hypertroph ncreases risk for adverse outcome after aortic va eplacement. Whether LV geometry influences mortali isk after aortic valve replacement is unclear. A hether LV mass or relative wall thickness (RWT) be redicts risk for adverse postoperative outcomes is nown. The purpose of this investigation was to exam he influence of LV geometry and LV hypertrophy orbidity and in-hospital mortality after aortic va eplacement, and to determine whether LV mass or R ad better prognostic ability. Methods. Between January 1996 and June 2004, 5,0 atients underwent aortic valve replacement. Preoper ive echocardiographic data was used to calculate ass and RWT. Left ventricular geometry was classifi nto one of four categories on the basis of LV ndexed to body height and RWT: (1) concentric hy rophy, (2) eccentric hypertrophy, (3) concentric remodeli nd (4) normal. Postoperative mortality and multisyst orbidities of patients with concentric geometries were

Abstract Background: Balloon valvuloplasty uses for treatment of aortic stenosis from 20 years ago. Regarding loss of information about results of balloon valvuloplasty of hereditary aortic stenosis, this study was done to determine prognosis and complication of balloon valvuloplasty during last 10 years. Methods: This study was done on existing data of all children with hereditary aortic...

Left ventricular remodelling pattern and its relation to clinical outcomes in patients with severe aortic stenosis treated with transcatheter aortic valve implantation
Introduction Left ventricular hypertrophy (LVH) is a common compensating process in the pressure overload mechanism of aortic stenosis (AS). Aim To identify a group of patients with a LVH pattern which may alter periprocedural and 1-year outcomes after transcatheter aortic valve implantation (TAVI). Material and methods Echocardiographic examinations of 226 patients with severe AS treated w...

Aorto-left ventricular tunnel (ALVT) is a rare congenital anomaly in which an abnormal communication connects the ascending aorta with the left ventricle, that results volume overload on left ventricle. It is clinically undistinguishable from aortic insufficiency. Its prompt and precise diagnosis is crucial since early surgical treatment is definitely indicated. In this report clinical,...
متن کاملSevere aortic stenosis without left ventricular hypertrophy: prevalence, predictors, and short-term follow up after aortic valve replacement.
OBJECTIVES The purpose of the present study in patients with severe aortic stenosis was to assess the prevalence of absent left ventricular hypertrophy (LVH) (determined according to mass criteria), to identify predictors of absent LVH, and to assess short-term left ventricular adaptation and prognosis after aortic valve replacement. METHODS Left ventricular mass (LVM) was determined by echoc...
