Q. Aortic regurgitation by Cardiac Catheterization?

Often cardiac catheterization is not indicated as reliable information for management decision making can be obtained through non-invasive methods. Before Aortic valve replacement (AVR) patient may have coronary angiography if indicated to rule out coronary artery disease. Similarly, cardiac catheterization or angiography may be done if there is any discrepancy between clinical findings and echocardiographic data. Hemodynamic measurements during exercise are occasionally helpful for determining the effect of aortic regurgitation on left ventricular function. In borderline cases right heart pressures on exercise may clarify the indications for AVR.
