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.
L'invention concerne des procédés et des dispositifs connexes, pour le traitement cardiaque, permettant le flux rétrograde dans une veine coronaire, et pouvant consister à faire circuler du sang dans un passage entre une structure anatomique qui contient du sang et une veine coronaire, dans le but de déclencher un flux rétrograde à l'intérieur de la veine. On peut aussi utiliser une pression interne de la veine coronaire, c'est-à-dire mesurer une pression interne, et au moins partiellement obstruer la veine en un point qui se trouve en amont du passage par rapport à un sens du flux rétrograde, sur la base de la mesure effectuée.
