Abstract:

Methods, and related devices, for treating a heart by allowing retrograde blood flow in a coronary vein may include flowing blood through a passageway between a blood-containing anatomical structure and a coronary vein so as to cause retrograde blood flow in the coronary vein. The methods, and related devices, may further include measuring an internal pressure of the coronary vein to determine a measured internal pressure and at least partially obstructing the coronary vein at a location upstream of the passageway relative to a direction of the retrograde blood flow based on the measured internal pressure.
