What drives the circulation? In this comprehensive review of existing circulation models, the conventional view that the heart is a pressure-propulsion pump is challenged. The existing models fail to explain an increasing number of observed circulatory phenomena. A unifying circulation model is proposed in which the blood, responding to metabolic demands of the tissues, is the primary regulator of cardiac output. This new model arises from accumulated clinical and experimental evidence. The hea…

Abstract
What drives the circulation? In this comprehensive review of existing circulation models, the conventional view that the heart is a pressure-propulsion pump is challenged. The existing models fail to explain an increasing number of observed circulatory phenomena. A unifying circulation model is proposed in which the blood, responding to metabolic demands of the tissues, is the primary regulator of cardiac output. This new model arises from accumulated clinical and experimental evidence. The heart, rather than being an organ of blood propulsion, assumes a secondary role and generates pressure by impeding the flow of blood. This is supported by examples from the fields of early embryonic circulation, comparative phylogeny, functional morphology, exercise physiology and a range of clinical scenarios. The Heart and Circulation: An Integrative Model offers a paradigm shift in the understanding of circulatory phenomena. It will become a valuable resource for all those clinicians, researchers, educators and students who, having been confronted with the paradox of the circulation, are looking for a broader interpretation.

Your surgeon will put an endovascular stent graft into your aorta. The aorta is the biggest artery in your body. Different diseases may affect your aorta. Your aorta needs to be repaired so it does not rupture (break) and cause severe (very bad) bleeding. This can lead to death. There are 2 ways to repair your aorta: TEVAR where the surgeon places a stent graft through a small incision in your groin, or through open repair where the surgeon makes a large incision through your breastbone and pot…

Abstract
Your surgeon will put an endovascular stent graft into your aorta. The aorta is the biggest artery in your body. Different diseases may affect your aorta. Your aorta needs to be repaired so it does not rupture (break) and cause severe (very bad) bleeding. This can lead to death. There are 2 ways to repair your aorta: TEVAR where the surgeon places a stent graft through a small incision in your groin, or through open repair where the surgeon makes a large incision through your breastbone and potentially down to your belly depending on the extent of your aneurysm. TEVAR surgery is an alternative to open surgery. The pamphlet outlines the benefits of TEVAR compared to open repair, and possible complications of this surgery. Your care before and after surgery and at home is outlined. Information about a healthy lifestyle is provided. Symptoms that need to be checked by your primary health care provider right away are noted as well as information about followup appointments.
