Question 1

During cardiac surgery involving opening of the right atrium, identification of the Triangle of Koch (Triângulo de Koch) is critical to avoid iatrogenic injury to the atrioventricular (AV) conduction system. What are the three anatomical boundaries that define the Triangle of Koch?

The tendon of Todaro, the septal leaflet attachment of the tricuspid valve, and the orifice of the coronary sinus. The crista terminalis, the Eustachian valve, and the fossa ovalis limbus. The membranous septum, the anterior leaflet of the mitral valve, and the non-coronary aortic sinus. The medial papillary muscle (Lancisi), the moderator band, and the supraventricular crest.

Correct Answer:

The tendon of Todaro, the septal leaflet attachment of the tricuspid valve, and the orifice of the coronary sinus.

Question 2

In coronary arterial anatomy, the blood supply to the sinoatrial (SA) node and the atrioventricular (AV) node is of paramount surgical importance. In a right-dominant coronary circulation, which vessels typically give rise to the SA node artery and the AV node artery, respectively?

SA node artery from the Left Anterior Descending artery (~70%) and AV node artery from the Circumflex artery (~90%). SA node artery from the Right Coronary Artery (~60%) and AV node artery from the Right Coronary Artery (~90%). SA node artery from the Circumflex artery (~80%) and AV node artery from the Diagonal branches (~60%). SA node artery from the Conus branch (~90%) and AV node artery from the Acute Marginal artery (~80%).

Correct Answer:

SA node artery from the Right Coronary Artery (~60%) and AV node artery from the Right Coronary Artery (~90%).

Question 3

The aortic root is a complex functional unit extending from the basal attachment of the aortic valve cusps to the sinotubular junction (STJ). Which statement regarding surgical aortic root anatomy is correct?

The left and right coronary ostia arise symmetrically from the non-coronary sinus of Valsalva above the interleaflet triangles. The membranous septum is located directly beneath the commissure between the left and right coronary cusps. The geometric aortic valve annulus is crown-shaped (scalloped), whereas the virtual basal ring is a planar construct at the nadir of the cusp insertions. The sinotubular junction separates the ventricular myocardium from the muscular portion of the aortic root.

Correct Answer:

The geometric aortic valve annulus is crown-shaped (scalloped), whereas the virtual basal ring is a planar construct at the nadir of the cusp insertions.

Question 4

In the left ventricle, the papillary muscles support the mitral valve leaflets via primary, secondary, and tertiary chordae tendineae. Why is the posteromedial papillary muscle significantly more vulnerable to ischemic rupture following myocardial infarction than the anterolateral papillary muscle?

The posteromedial papillary muscle receives blood solely from the conus branch of the right coronary artery. The anterolateral papillary muscle has no chordal attachments to the posterior mitral leaflet, reducing mechanical wall tension. The posteromedial papillary muscle is composed entirely of fibrous connective tissue with minimal vascular microcirculation. The posteromedial papillary muscle relies on a single arterial blood supply (usually the posterior descending artery - PDA), whereas the anterolateral papillary muscle has dual blood supply (LAD and LCx).

Correct Answer:

The posteromedial papillary muscle relies on a single arterial blood supply (usually the posterior descending artery - PDA), whereas the anterolateral papillary muscle has dual blood supply (LAD and LCx).

Question 5

During cardiac surgical exposure, passing an umbilical tape or vascular clamp through the transverse pericardial sinus of Theile allows circumferential control of which great vessels?

The ascending aorta and the main pulmonary artery, separating them from the superior vena cava and atria. The superior vena cava and inferior vena cava, separating them from the right pulmonary veins. The right and left pulmonary veins, separating them from the posterior pericardial wall. The left main coronary artery and the coronary sinus, separating them from the left ventricle.

Correct Answer:

The ascending aorta and the main pulmonary artery, separating them from the superior vena cava and atria.
