as mitral stenosis worsens and the mitral valve area decreases, right heart pressures increase to maintain cardiac output across the stenotic valve with a pressure gradient between the left atrium ...

In this setting, rheumatic mitral valve disease is almost always ... At cardiac catheterization for aortic stenosis, the transvalvular pressure gradient is determined by directly recording ...

The replacement system is launching into markets already served by repair devices, namely Edwards’ Pascal and Abbott’s ...

Valve diseases are mostly dynamic ... may be used in patients with mitral stenosis. Measuring the mean transvalvular mitral gradient and systolic pulmonary pressure at exercise may help to explain ...

The pathophysiologic changes caused by a calcified aortic valve are the same as those caused by other forms of aortic stenosis and are related to the pressure gradient that develops between the ...

The mitral valve was normal. Comment. The squeaking quality in a predominantly apical murmur led to a diagnosis of aortic stenosis in addition to coronary and hypertensive heart disease.
