Ventricular Long-Axis Contraction as an Earlier Predictor of Outcome in Asymptomatic Aortic Regurgitation
2007, American Journal of CardiologyCitation Excerpt :LV systolic wall stress, which affects both myocardial contractility and ventricular fibrosis, increased in patients with chronic AR.21,22 In the present study and in keeping with previous reports,23 systolic wall stress at rest was similar between the groups at baseline. However, patients with lateral mitral wave velocity <9 cm/s at zero time point had higher LV systolic wall stress 12 months later compared with patients with higher mitral annulus velocity at zero time point.
Left Ventricular Wall Stress in Patients With Severe Aortic Insufficiency With Finite Element Analysis
2006, Annals of Thoracic SurgeryCitation Excerpt :Siemienczuk and colleagues [15] reported that meridional ESS of 8.60E+04 dynes/cm2 or more was associated with progression to AVR and the development of LV dysfunction or symptoms after surgery. Percy and colleagues [5] addressed the prognostic significance of LV wall stress for outcome prediction in asymptomatic patients with AI. The authors reported that ESS was a significant discriminator between patients that remained unchanged clinically at follow-up and those that progressed to decompensated LV volume overload or death related to aortic valve disease.

2003, Annals of Thoracic SurgeryCitation Excerpt :Greenberg and coworkers [28] examined the association between the exercise ejection fraction response and systolic wall stress and concluded that patients whose ejection fraction falls during exercise had elevated resting LV systolic wall stress, suggesting that LV hypertrophy has not been adequate. In another study, Percy and colleagues [6] addressed the prognostic significance of LV wall stress for outcome prediction in asymptomatic patients with AI. The authors reported that ESS was a significant discriminator between patients that remained unchanged clinically at follow-up and those that progressed to decompensated LV volume overload or death related to aortic valve disease.
