24 de sept. de 2021 · The combination of aortic stenosis (AS) and mitral regurgitation (MR) is common in patients with degenerative valvular disease. It is characterized by having complex pathophysiology, leading to potential diagnostic pitfalls.
1 de may. de 2012 · In patients with critical aortic stenosis, the Carabello sign may be present, in which the catheter across the valve itself will cause further obstruction to outflow. 13 This sign occurs in valve areas of <0.7 cm 2 when 7F or 8F catheters are used to cross the valve.
7 de oct. de 2019 · The impact of aortic valve replacement (AVR) for severe aortic stenosis on mitral stenosis is unknown. This study aimed to assess the effect of AVR on mitral stenosis hemodynamics and the clinical outcomes of patients with severe aortic stenosis with and without mitral stenosis.
27 de jul. de 2017 · Patients with severe aortic stenosis (AS) and normal ejection fraction (EF) can paradoxically present low-transaortic flow and worse prognosis. The role of co-existing mitral regurgitation (MR) in determining this haemodynamic inconsistency has never been quantitatively explored.
11 de mar. de 2021 · In particular a detailed assessment of the mechanism of mitral regurgitation should be obtained as this may provide clues as to whether the MR will improve simply by intervening on the aortic valve, or whether dual valve intervention is needed .
This review aims to summarize the most critical pathophysiological mechanisms underlying AS when associated with mitral regurgitation, mitral stenosis, aortic regurgitation, and tricuspid regurgitation. We will focus on echocardiography, clinical implications, and the most important treatment strategies.
