The phrenic nerve runs on the surface of the carotid artery.
The central fibrous body lies at the junction of the mitral, tricuspid, and pulmonary valves.
The sinus node lies in Waterston's groove.
The artery to the sinus node can be injured during operations on the mitral valve.
The boundaries of the triangle of Koch are the tendon of Todaro, the septal leaflet of the tricuspid valve, and the fossa ovalis.
Question 2: Which of the following statements is true?
The posterior leaflet of the mitral valve is in continuity with the aortic valve.
A dominant left coronary artery is at particular risk during mitral valve surgery.
The right ventricle supraventricular crest is also known as the moderator band.
The left ventricular outflow tract is a complete muscular structure, similar to the right ventricular outflow tract.
The anterior leaflet of the mitral valve usually has 2 direct septal attachments
Question 3: Which of the following is true regarding coronary artery anatomy?
90% of people have a right dominant coronary artery system.
The coronary ostia are rarely located outside of their respective sinuses.
The most frequent coronary artery anomaly is origin from the noncoronary sinus.
An aberrant circumflex artery is typically large and supplies the majority of the inferior wall.
Congenital aortic stenosis has a higher incidence of left coronary dominance.
Question 4: Which of the following statements is true?
Less than 1% of patients have an anomalous origin of the left coronary artery from the right coronary artery.
Anomalies of the left coronary artery are less common than of the right coronary artery.
The left anterior descending artery infrequently supplies a portion of the posterior septum.
Less than 50% of coronary venous return flows through the coronary sinus.
Most collaterals occur between the circumflex and the left anterior descending arteries.
