Primary dilated cardiomyopathy- MedGen UID:
- 2880
- •Concept ID:
- C0007193
- •
- Disease or Syndrome
Familial dilated cardiomyopathy is a genetic form of heart disease. It occurs when heart (cardiac) muscle becomes thin and weakened in at least one chamber of the heart, causing the open area of the chamber to become enlarged (dilated). As a result, the heart is unable to pump blood as efficiently as usual. To compensate, the heart attempts to increase the amount of blood being pumped through the heart, leading to further thinning and weakening of the cardiac muscle. Over time, this condition results in heart failure.\n\nIt usually takes many years for symptoms of familial dilated cardiomyopathy to cause health problems. They typically begin in mid-adulthood, but can occur at any time from infancy to late adulthood. Signs and symptoms of familial dilated cardiomyopathy can include an irregular heartbeat (arrhythmia), shortness of breath (dyspnea), extreme tiredness (fatigue), fainting episodes (syncope), and swelling of the legs and feet. In some cases, the first sign of the disorder is sudden cardiac death. The severity of the condition varies among affected individuals, even in members of the same family.
Hypertrophic cardiomyopathy- MedGen UID:
- 2881
- •Concept ID:
- C0007194
- •
- Disease or Syndrome
Hypertrophic cardiomyopathy (HCM) is defined by the presence of increased ventricular wall thickness or mass in the absence of loading conditions (hypertension, valve disease) sufficient to cause the observed abnormality.
Restrictive cardiomyopathy- MedGen UID:
- 40111
- •Concept ID:
- C0007196
- •
- Disease or Syndrome
Restrictive left ventricular physiology is characterized by a pattern of ventricular filling in which increased stiffness of the myocardium causes ventricular pressure to rise precipitously with only small increases in volume, defined as restrictive ventricular physiology in the presence of normal or reduced diastolic volumes (of one or both ventricles), normal or reduced systolic volumes, and normal ventricular wall thickness.
Mitral regurgitation- MedGen UID:
- 7670
- •Concept ID:
- C0026266
- •
- Disease or Syndrome
An abnormality of the mitral valve characterized by insufficiency or incompetence of the mitral valve resulting in retrograde leaking of blood through the mitral valve upon ventricular contraction.
Cardiogenic shock- MedGen UID:
- 48650
- •Concept ID:
- C0036980
- •
- Pathologic Function
Severely decreased cardiac output with evidence of inadequate end-organ perfusion (i.e., tissue hypoxia) in the presence of adequate intravascular volume.
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.
Left atrial enlargement- MedGen UID:

- •Concept ID:
- C0238705
- •
- Finding
Increase in size of the left atrium.
Biventricular hypertrophy- MedGen UID:
- 807328
- •Concept ID:
- C0281788
- •

Thickening of the heart walls in both ventricles.
Right atrial enlargement- MedGen UID:
- 677114
- •Concept ID:
- C0748427

Increase in size of the right atrium.
Myofiber disarray- MedGen UID:
- 1615672
- •Concept ID:
- C3671015
- •
- Finding
A nonparallel arrangement of cardiac myocytes.
Left ventricular noncompaction cardiomyopathy- MedGen UID:
- 866782
- •Concept ID:
- C4021133
- •
- Disease or Syndrome
Left ventricular non-compaction (LVNC) is characterized by prominent left ventricular trabeculae and deep inter-trabecular recesses. The myocardial wall is often thickened with a thin, compacted epicardial layer and a thickened endocardial layer. In some patients, LVNC is associated with left ventricular dilatation and systolic dysfunction, which can be transient in neonates.

- Finding
Abnormally increased size of the liver.
Clonus- MedGen UID:
- 40341
- •Concept ID:
- C0009024
- •
- Sign or Symptom
A series of rhythmic and involuntary muscle contractions (at a frequency of about 5 to 7 Hz) that occur in response to an abruptly applied and sustained stretch.
Tremor- MedGen UID:
- 21635
- •Concept ID:
- C0040822
- •
- Sign or Symptom
An unintentional, oscillating to-and-fro muscle movement about a joint axis.
Facial palsy- MedGen UID:
- 87660
- •Concept ID:
- C0376175
- •
- Disease or Syndrome
Facial nerve palsy is a dysfunction of cranial nerve VII (the facial nerve) that results in inability to control facial muscles on the affected side with weakness of the muscles of facial expression and eye closure. This can either be present in unilateral or bilateral form.
