Tortuosity of coronary arteries in chronic pressure and volume overload.

The role of coronary tortuosity in the pathophysiology of chronic pressure and volume overload is still unclear. A new method for measuring coronary tortuosity in patients with chronic pressure and volume overload was evaluated in 62 patients. Sixteen controls, 14 patients with arterial hypertension, and 32 patients with aortic regurgitation were included in the present analysis.
