Q

Mitral Annular Calcification can lead to:

A
  • Regurgitation by interfering with physiologic contraction of the valve ring
  • Stenosis by impairing opening of the mitral leaflets
  • Arrhythmias and occasionally sudden death by penetration of calcium deposits to a depth sufficient to impinge on the atrioventricular conduction system.

An infection in the tissues contiguous to the pericardium— for example, a bacterial pleuritis—may incite sufficient irritation of the parietal pericardial serosa to cause a sterile serous effusion that can progress to serofibrinous pericarditis and ultimately to a frank suppurative reaction.

Q

The four cardinal features of this defect are (1) VSD, (2) obstruction
of the right ventricular outflow tract (subpulmonary
stenosis), (3) an aorta that overrides the VSD, and (4) right
ventricular hypertrophy (Fig. 12-6A). All of these features
result embryologically from anterosuperior displacement
of the infundibular septum.
