Insights
Isolated left ventricular noncompaction, a cardiac genetic disorder, can manifest solely as atrial arrhythmias. This case highlights a rare presentation of ventricular noncompaction in a young woman.
Area of Science:
- Cardiology
- Genetics
- Cardiac Morphology
Background:
- Isolated left ventricular noncompaction (ILVNC) is an age-independent genetic cardiac disorder.
- It arises from defects in endo-myocardial morphogenesis.
- Diagnosis is typically noninvasive via echocardiography or cardiac magnetic resonance.
Observation:
- A young woman presented with an unusual clinical manifestation of ILVNC.
- Her primary and sole clinical sign was an atrial parasystole.
- This contrasts with the more commonly reported atrial and ventricular arrhythmias.
Findings:
- The case details the morphological and functional findings of ILVNC.
- It emphasizes the potential for atypical presentations of this cardiac condition.
- Atrial parasystole was the exclusive clinical indicator in this patient.
Implications:
- This case expands the understanding of ILVNC's clinical spectrum.
- It suggests that atrial parasystole should be considered in the differential diagnosis of ILVNC.
- Further research into the genetic and morphogenetic underpinnings of varied ILVNC presentations is warranted.
Abstract:
Isolated left ventricular noncompaction is a recently recognized age-independent cardiac genetic disorder caused by heterogeneous defects in endo-myocardial morphogenesis. Transthoracic echocardiography and cardiac magnetic resonance are the most reliable techniques to make a diagnosis of the disease, noninvasively. Arrhythmic atrial and ventricular disorders have been reported in 20-50% of these patients. The morphological and functional findings are described in a young woman in whom the exclusive clinical sign of isolated ventricular noncompaction was an atrial parasystole.
