Stopped: Subject accrual too difficult
This study aims to evaluate the accuracy of the echocardiographic data obtained from patients with calcifications in the mitral valve who are undergoing a cardiac (heart) catheterization. Echocardiography is a non-invasive (does not break the skin) procedure used to see an image of the heart. It uses harmless sound waves to create an image of the heart on a computer screen. These images will show the valves of the heart, how well the heart is pumping blood, the blood flow across these valves and how large the heart is. A silver paddle-shaped device is moved easily over the skin to capture these images. Calcification (hardening) of the heart valves and heart rings (fibrous tissue surrounding the valves) is a common finding and it increases with age. The presence of calcification changes the blood flow through the heart valves. This makes any echocardiographic data (information) obtained from patients with calcifications difficult to interpret.
