During this procedure, the femoral artery is accessed and a catheter is advanced from the leg until it reaches the coronary artery supplying blood to the thickened septum. Once the catheter is properly positioned in the septal artery, a tiny balloon at the tip of the catheter is inflated, blocking blood flow. One to two CCs of absolute alcohol is then injected through the catheter and into the septal artery. The alcohol directly damages the heart muscle, which, over the course of several weeks to months, will reduce the thickness of the septum. By thinning this area, the mitral valve will not move toward the septum, eliminating obstruction to blood flow. This restores the pressures in the heart to normal, resulting in a significant improvement or elimination of heart failure symptoms. It can take several weeks to months for the septum to completely thin and the full benefits of the procedure to be felt.
