Definition

Congenital heart block (CHB) is a rare disorder of atrioventricular conduction, characterized by absence of conduction of atrial impulses to the ventricles with slower ventricular rhythm (atrioventricular dissociation). CHB can occur in association with immunological evidence of maternal connective disease (autoimmune CHD), fetal structural CHD or can be idiopathic. [from ORDO]

Mitral regurgitation
MedGen UID:

Atrial arrhythmia
MedGen UID:

Myocardial fibrosis
MedGen UID:
56239
•Concept ID:
C0151654
•
Pathologic Function
Myocardial fibrosis is characterized by dysregulated collagen turnover (increased synthesis predominates over unchanged or decreased degradation) and excessive diffuse collagen accumulation in the interstitial and perivascular spaces as well as by phenotypically transformed fibroblasts, termed myofibroblasts.

MedGen UID:
209232
•Concept ID:
C0878544
•
Disease or Syndrome
A myocardial disorder in which the heart muscle is structurally and functionally abnormal, in the absence of coronary artery disease, hypertension, valvular disease and congenital heart disease sufficient to cause the observed myocardial abnormality.
