Ventricular arrhythmias due to cardiac ryanodine receptor calcium release deficiency syndrome(VACRDS)

MedGen UID:
1781114
•Concept ID:
C5542154
•
Disease or Syndrome
Synonym: Autosomal dominant cardiac arrhythmia (Kuhn)
 
Gene (location): RYR2 (1q43)
 
Monarch Initiative: MONDO:0020745
OMIM®: 115000

Definition

Ventricular arrhythmias due to cardiac ryanodine receptor calcium release deficiency syndrome (VACRDS) is characterized by syncope, cardiac arrest, and/or sudden unexpected death. Polymorphic ventricular tachycardia and ventricular fibrillation have been documented in these patients. Symptoms generally occur with physical activity or emotional stress, but unlike typical catecholaminergic ventricular tachycardia (CPVT), arrhythmias are not reproducible on exercise stress testing or adrenaline challenge (Sun et al., 2021). Mutation in the RYR2 gene also causes catecholaminergic polymorphic ventricular tachycardia-1 (CPVT1; 604772). [from OMIM]

Clinical features

From HPO
Sudden cardiac death
MedGen UID:
38841
•Concept ID:
C0085298
•
Pathologic Function
The heart suddenly and unexpectedly stops beating resulting in death within a short time period (generally within 1 h of symptom onset).

Torsades de pointes
MedGen UID:
21214
•Concept ID:
C0040479
•
Disease or Syndrome
A type of ventricular tachycardia characterized by polymorphioc QRS complexes that change in amplitue and cycle length, and thus have the appearance of oscillating around the baseline in the EKG.

Ventricular fibrillation
MedGen UID:
21844
•Concept ID:
C0042510
•
Disease or Syndrome
Uncontrolled contractions of muscles fibers in the left ventricle not producing contraction of the left ventricle. Ventricular fibrillation usually begins with a ventricular premature contraction and a short run of rapid ventricular tachycardia degenerating into uncoordinating ventricular fibrillations.

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.

Aborted sudden cardiac death
MedGen UID:

•
Finding
Cardiac arrest that would have led to rapid and unexpected death had an intervention not taken place to prevent it.
