Congestion of the lungs and fluid accumulation are common. Fluid can also build up in the abdomen and around the lungs, if the right side of the heart is also involved. Congestion and fluid buildup indicate heart failure. Dogs with DCM-induced heart failure often have left-sided congestive failure.
Medical Definition of COLLATERAL CIRCULATION. : circulation of blood established through enlargement of minor vessels and anastomosis of vessels with those of adjacent parts when a major vein or artery is functionally impaired (as by obstruction); also: the modified vessels through which such circulation occurs.edical Definition of COLLATERAL CIRCULATION. : circulation of blood established through enlargement of minor vessels and anastomosis of vessels with those of adjacent parts when a major vein or artery is functionally impaired (as by obstruction); also: the modified vessels through which such circulation occurs.
The study, published online today in the European Heart Journal, shows that patients with lots of these vessels have a 36% reduced risk of mortality, highlighting their importance as a therapeutic target. Coronary collaterals are tiny, specialised blood vessels that connect the larger vessels in the heart. They can be thought of as the heartâs âback-up systemâ as they are essentially invisible until activated, when they can enlarge their diameters in order to carry significant blood flow and bypass blockages.
