Hemodynamics
Hemodynamics is the study of blood flow dynamics within the circulatory system. In the case of the balanced AV canal, there is a distinctive pattern of blood flow. A single atrioventricular valve allows both the left and right atria to connect with a common ventricle, leading to specific hemodynamic challenges.
Typically, the balanced AV canal leads to two major circulatory patterns:
- Increased pulmonary blood flow: The single valve may cause an excessive flow of blood to the lungs. This results in pulmonary overcirculation, leading to lung congestion.
- Decreased systemic blood flow: Conversely, the systemic circulation can be compromised. The heart's efficiency diminishes due to the compromised separation of oxygenated and deoxygenated blood.
Understanding these patterns aids in developing proper treatment protocols. Surgical correction typically aims to re-establish normal flow dynamics, thus improving the patient's overall circulation.
Impact on Cardiac Function
The impact of a balanced AV canal on cardiac function is profound. A normal heart has two distinct ventricles that efficiently manage blood flow to the body and lungs. In contrast, individuals with a balanced AV canal often face challenges such as:
- Heart chamber dilation: The pressure overload from excess blood flow can lead to the enlargement of cardiac chambers. This increases the heart's workload, potentially leading to heart failure.
- Arrhythmias: Structural changes can elicit irregular heartbeats. These disturbances are often precipitated by the altered electrical pathways, stemming from changes in chamber size and blood flow.
Furthermore, patients may exhibit symptoms like fatigue, poor growth, and respiratory distress due to the heart's compromised function.
