Overview
Cardiac catheterization can be used to measure the PCWP and the LVEDP. These are important predictors of the filling pressure and the degree of myocardial disease progression in dilated cardiomyopathy.
Other Diagnostic Studies
Cardiac Catheterization
The predictors of the filling pressure and the degree of myocardial disease progression are essentially the mean pulmonary wedge pressure (PCWP, which is equal to the mean left atrial pressure in the absence of mitral stenosis) and the left ventricular end diastolic pressure (LVEDP).
- The diastolic phase of the cardiac cycle is normally characterized by rapid blood filling at low left ventricular pressures
- The hallmark of diastolic dysfunction is elevated left ventricular end diastolic pressure or filling pressure
- Cardiac catheterization is an invasive diagnostic tool used to measure the PCWP and the LVEDP
- The cut off values used for the diagnosis of diastolic dysfunction are:
- PCWP >12 mmHg
- LVEDP> 16mmHg [1]
