Abstract:
Fistulous communications between the common iliac arteries and inferior vena cava are very uncommon and usually occur as a result of trauma, aneurysmal rupture, or endovascular repair. They can present with signs of high output cardiac failure including hypotension, venous congestion, and pulmonary hypertension. This case outlines the utility of CTA in diagnosing iliocaval fistulas and the importance of considering this diagnosis in a patient with signs of right heart strain and high output cardiac failure.

Cardiac Output II: Effect of Stroke Volume on Cardiac Output
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...
Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...
