Multivalvular Disease

Answer 1

The right fibrous trigone is the strongest part of the heart’s fibrous skeleton.

Question 2

The central Fibrous body connects which valves:

Answer 2

The central fibrous body is the core of the heart’s skeleton, which unites the aortic, mitral, and tricuspid valves and is made up by the right fibrous trigone and thick division between the left ventricular outflow tract, the right atrium, and right ventricle.

Question 3

The central fibrous body is made up of:

Answer 3

The central fibrous body is the core of the heart’s skeleton, which unites the aortic, mitral, and tricuspid valves and is made up by the right fibrous trigone and thick division between the left ventricular outflow tract, the right atrium, and right ventricle.

Answer 4

The aortic, mitral, and tricuspid valves stradle the heart’s fibrous skeleton with the aortic valve lying most central.

Answer 5

The pulmonary artery is connected to the aortic valve by the conal septum.

Answer 6

• The circumflex sweeps aroundthe mitral valve anterior to posterior, running between the base of the left atrial appendage and P1 of theposterior leaflet.
• The close relationship between the anterolateral trigone and the circumflex is important as itcan be misleading and lead to significant circumflex artery stenosis or occlusion.

Question 7

Order of Operation

Aortic/Mitral replacement

Answer 7

Mitral than aortic valve.
1. Expose AV, resect leaflets, and size annulus
2. Mitral replacement: By placing shallower sutures between the left and right trigones, narrowing of the aortic annulus is avoided and provides adequate placement of the aortic valve sutures.
3. AV replacement
