Timing surgery in mitral regurgitation: defining risk and optimising intervention using stress echocardiography
Mitral regurgitation (MR) is the second most common form of valvular disease requiring surgery. Correct identification of surgical candidates and optimising the timing of surgery are key in management. For primary MR, this relies upon a balance between the peri-operative risks and rates of successful repair in patients undergoing early surgery when asymptomatic with the potential risk of irreve...
متن کاملReversed mitral diastolic gradient in aortic incompetence.
Information about the haemodynamics of severe aortic regurgitation, though a subject of much interest, is still scanty (Segal, Harvey, and Hufnagel, 1956; Dodge, Sandler, and Evans, 1960; Meadows et al., 1963). Up to 1964, only seven cases of aortic regurgitation in which there was a reversed mitral valve gradient in late diastole could be found by Rees et al. (1964) in their review of the publ...
متن کاملEffect of dobutamine stress echocardiography on mitral regurgitation.
OBJECTIVES This study was performed to examine the effect of dobutamine stress echocardiography on mitral regurgitation and to test the hypothesis that mitral regurgitation will increase in patients with an ischemic response. BACKGROUND New or worsening mitral regurgitation during stress testing has been proposed as a marker of ischemia. However, it is unclear whether ischemia induced by dobu...
متن کاملSingle-centre experience with mitral valve repair in asymptomatic patients with severe mitral valve regurgitation.
OBJECTIVES Guidelines recommend surgical mitral valve repair in selected patients with asymptomatic severe mitral valve regurgitation (MR), but the role of repair remains a matter of debate. Survival analyses of operated asymptomatic patients have been reported, but long-term haemodynamics and quality of life are not well defined. The aim of this study was to report the long-term follow-up focu...
متن کاملEffect of altered haemodynamics on the developing mitral valve in chick embryonic heart
Intracardiac haemodynamics is crucial for normal cardiogenesis, with recent evidence showing valvulogenesis is haemodynamically dependent and inextricably linked with shear stress. Although valve anomalies have been associated with genetic mutations, often the cause is unknown. However, altered haemodynamics have been suggested as a pathogenic contributor to bicuspid aortic valve disease. Conve...
