We describe a stepwise procedure for creating pressure overload and left ventricular hypertrophy in Wistar rats by constriction of the ascending aorta using a small metallic clip. This model is extensively used for studying remodeling changes during cardiac hypertrophy and for identifying and evaluating strategies for regression of such changes.

The Aorta

The aorta is the largest artery in the human body. It originates from the left ventricle of the heart and extends down to the abdomen, where it splits into two smaller arteries. Structurally, it can be divided into four main parts: the ascending aorta, the aortic arch, the thoracic aorta, and the abdominal aorta. The average diameter of the aorta is approximately 2-3 cm, but the size can vary depending on the section of the aorta and the individual's age, sex, and body size. The aorta is...

Direct Re-implantation of Left Coronary Artery into the Aorta in Adults with Anomalous Origin of Left Coronary Artery from the Pulmonary Artery (ALCAPA)

Surgical correction of ALCAPA is highly recommended, regardless of age or the degree of intercoronary collateralization. This protocol presents a technique for the direct re-implantation of adult-type ALCAPA into the aorta to re-establish the dual-coronary perfusion. Whenever feasible, direct re-implantation is preferred to other surgical correction techniques.
FAQs
Its elastic wall expands when the left ventricle ejects blood during contraction and then recoils as the ventricle relaxes. This recoil helps sustain forward movement of blood during the interval between contractions rather than allowing flow to stop when ventricular pumping pauses. The mechanism links vessel elasticity with continuous systemic circulation and blood-pressure regulation.
The aortic valve controls the entry of blood from the left ventricle into the ascending aorta. It opens during ventricular contraction, allowing oxygen-rich blood to enter the vessel, and its position marks the beginning of the route toward the aortic arch. This timing coordinates cardiac pumping with arterial flow into systemic circulation.
The coronary arteries branch near the origin of the ascending aorta and supply the heart muscle itself. Their proximity connects the first arterial segment directly with myocardial blood supply, while the remaining aortic pathway carries blood toward the wider systemic circulation. Studying this region therefore links major-vessel anatomy with the biology of cardiac nourishment.
Aneurysms, dissections, and congenital abnormalities are important disorders involving this region, but they represent different categories of structural cardiovascular problem. Because the ascending aorta lies immediately beyond the aortic valve and near the coronary branches, evaluating it can provide information relevant to cardiovascular risk. Findings may also help guide decisions about treatment.
Imaging provides a way to assess the structure of the ascending aorta in relation to cardiovascular disorders and risk. It can support evaluation when an aneurysm, dissection, or congenital abnormality is a concern, while also contributing to treatment planning. In biology and medicine, imaging turns anatomical knowledge of this segment into clinically useful assessment.
Surgical assessment helps determine how a disorder affecting the ascending aorta should be managed. Its importance follows from the region’s connections with the left ventricle, aortic valve, coronary arteries, and route to the aortic arch. Examining these relationships supports treatment planning while applying cardiovascular anatomy to conditions such as aneurysms, dissections, and congenital abnormalities.
