Figure 8. Flow chart outlining the use of ERNA in monitoring doxorubicin cardiotoxicity.

Figure 9. First pass study of right ventricle. Immediately after tracer injection into an antecubital vein, a gated study was acquired in the brief period that activity traversed the right heart but before arrival of tracer in the left heart. The study is typically acquired in an anterior or RAO projection to optimally separate right atrium (thin arrow) and right ventricle (arrowhead). With this technique, the right ventricular ejection fraction can be determined in the same manner as the left ventricular ejection fraction in an ERNA study.

Right Ventricle

Evaluation of right ventricular function is important in patients who are hemodynamically unstable following inferior infarction, patients with pulmonary hypertension and in patients suspected of having arrhythmogenic right ventricular dysplasia (fibro-fatty infiltration resulting in a dilated hypokinetic right ventricle). Right ventricular size and wall motion can be assessed on an ERNA study. Overlap of other cardiac structures (especially the right atrium) on the right ventricle limits the accuracy of a right ventricular EF determination. For this reason, a first pass study (see FAQs) is commonly used to assess the right ventricular EF (Fig. 9).

Blood Pressure Health

Blood Pressure Health

Your heart pumps blood throughout your body using a network of tubing called arteries and capillaries which return the blood back to your heart via your veins. Blood pressure is the force of the blood pushing against the walls of your arteries as your heart beats.Learn more...
