Advanced Small Cardiac Vein Quiz

Q1. A vein ascending near the acute margin of the heart alongside the right marginal artery is most likely which vessel?

• Great cardiac vein
• Oblique vein of the left atrium
• Small cardiac vein
• Middle cardiac vein

Q2. After accompanying the right marginal artery, the small cardiac vein changes its principal arterial relationship to which vessel?

• Left marginal artery
• Circumflex artery
• Anterior interventricular artery
• Right coronary artery

Q3. During dissection of the right atrioventricular groove, a vein is found accompanying the right coronary artery toward the posterior surface. Which vein is most likely?

• Small cardiac vein
• Middle cardiac vein
• Anterior interventricular vein
• Great cardiac vein

Q4. Why might the small cardiac vein be difficult to identify during anatomical dissection?

• Its size and presence are variable
• It is always located inside the right ventricular cavity
• It becomes an artery after birth
• It normally lies within the aortic wall

Q5. Which finding would favor identification of a vessel as the small cardiac vein rather than an anterior cardiac vein?

• The vessel carries blood toward the right ventricular myocardium
• The vessel drains directly into the right atrium
• The vessel continues posteriorly to the coronary sinus
• The vessel arises from the right aortic sinus

Q6. Which topographic combination most strongly identifies the small cardiac vein?

• Right margin with the right marginal artery, then right coronary sulcus with the right coronary artery
• Anterior interventricular sulcus with the LAD, then left coronary sulcus with the circumflex artery
• Interatrial septum with the AV bundle
• Posterior interventricular sulcus with the posterior interventricular artery throughout

Q7. Which cardiac vein is the closest topographic counterpart to the small cardiac vein on the left side of the coronary sulcus?

• Middle cardiac vein
• Anterior cardiac veins
• Pulmonary veins
• Great cardiac vein

Q8. Why is knowledge of variation in the small cardiac vein relevant to coronary venous procedures?

• It is the principal arterial route used for coronary angiography
• It always provides the only route into the coronary sinus
• Its variable caliber and occasional absence can alter the expected venous anatomy
• Its presence determines whether the heart has an aortic valve

Q9. A vessel along the right ventricular margin carries blood toward the coronary sinus rather than away from the aorta. Which feature confirms that it is venous rather than the adjacent right marginal artery?

• It arises from the right aortic sinus
• It supplies the right ventricular myocardium
• It is a branch of the right coronary artery
• Its blood flow is directed from the myocardium toward the coronary venous system

Q10. Which statement best integrates the anatomy of the small cardiac vein?

• It is an arterial branch supplying the right atrium and AV node
• It occupies the posterior interventricular sulcus and always accompanies the posterior interventricular artery
• It drains the left ventricular apex through the anterior interventricular sulcus into the left atrium
• It drains the right heart, follows right coronary arterial landmarks, and usually terminates in the coronary sinus
