Aortic Valve Area, Stroke Volume, Left Ventricular Hypertrophy, Remodeling, and Fibrosis in Aortic Stenosis Assessed by Cardiac Magnetic Resonance Imaging.By CMR, however, planimetric AVA(Valvar area) was larger in LF/LG (0.540.08 cm2/m2) and LG/NF (0.610.08 cm2/m2) than in HG/LF (0.460.07 cm2/m2; P<0.05) AS, and indexed LV mass was lower in LG/LF (7512 g/m2) and LG/NF (8118 g/m2) than in HG/LF (10027 g/m2; P<0.05) AS.CMR confirmed that classification of AS patterns by TTE was overall accurate. We observed a good correlation between measurements of LVOT, stroke volume, and aortic valve area between TTE and CMR.Patients with paradoxical LG/LF and LG/NF AS had less severe AS severity, less hypertrophy and remodeling, and a similar amount of focal fibrosis compared with HG AS...E agora, senhores ecocardiografistas, como explicar os achados de area valvar superior na estenose aortica com gradiente baixo????. .O blog EchoTalk tem muitos leitores fieis em paises da America Latina, Europa e alguns da Africa e Asia.

In addition, stress testing is very helpful in evaluating women with MS who are contemplating pregnancy. Pregnancy causes an obligatory increase in cardiac output (transmitral flow), heart rate (shorter diastolic filling time), and total blood volume, each of which increases the MV transvalvular gradient and thus left atrial pressure.Consequently, many women with MS often present with symptoms for the first time during pregnancy due to the increase in pulmonary venous pressure (secondary to increased left atrial pressure). Exercise stress testing is a useful way to assess how well MS patients will tolerate pregnancy. It further helps identify which patients may benefit from no therapy, beta-blockade, or prophylactic PMBV or even surgery before becoming pregnant..Uso do ecoestresse de esforco embicicleta na Estenose Mitral. Facil e rapido.. ...Novo endereco para o blog : www.echotalkblog.com...ResultsWe found a modest decrease in RVIT dimensions (P < 0.05), but increase in RVOT dimensions with advancing age (P < 0.05). A small decrease in RVOT fs with age was also found (P < 0.05). Estimated pulmonary pressures and pulmonary vascular resistance increased (P < 0.001) as did RVOT wall thickness (P < 0.001), but RV diastolic function was not altered (P < 0.001) with age. Despite correction for the BSA, males showed larger RVIT dimensions (P < 0.001 for both), but RVOT end-diastolic dimension was larger in females (P < 0.05). RVIT and RVOT fractional shortening were increased in females (P < 0.01 for both)..ConclusionIn a cohort of normal individuals, age has significant impact on right ventricular structure and function, inlet area falls and outflow tract dimensions increase and fractional shortening also increase in females. In addition, RV outflow tract wall thickens significantly and Doppler markers of pulmonary vascular resistance show a consistent rise. The age-related changes should carefully be considered when commenting
