Left Ventricular Noncompaction

Also known as LVNC, isolated LVNC, noncompaction cardiomyopathy

Left Ventricular Noncompaction is a structural cardiomyopathy characterised by a heavily trabeculated left ventricular myocardium with deep intertrabecular recesses, thought to result from arrest of the normal embryonic compaction process,

About Left Ventricular Noncompaction

Left Ventricular Noncompaction is a structural cardiomyopathy characterised by a heavily trabeculated left ventricular myocardium with deep intertrabecular recesses, thought to result from arrest of the normal embryonic compaction process, and associated with heart failure, ventricular arrhythmias, and thromboembolic events. The condition may occur in isolation or in association with congenital heart defects, neuromuscular diseases, or metabolic disorders, and can be inherited or sporadic. TAZ gene mutations cause Barth syndrome, a syndromic form presenting in infant males with LVNC, skeletal myopathy, neutropenia, and growth retardation.

Common clinical features

Heart failure with reduced or preserved ejection fractionPalpitations and ventricular arrhythmiasThromboembolic events including systemic embolism and strokeProminent left ventricular trabeculations on echocardiography or MRI (NC:C ratio >2.3)Conduction abnormalities and bundle branch blockExercise intolerance and fatigueSudden cardiac death riskIn Barth syndrome: skeletal muscle weakness and recurrent infections

Before you apply

Things trial teams commonly ask about for Left Ventricular Noncompaction. Not eligibility rules; those are set by each study.

  • Echocardiographic or cardiac MRI confirmation of LVNC using standardised criteria (e.g., Jenni or Petersen criteria) is required for enrolment; bring recent imaging with quantified trabeculation ratios.
  • Genetic testing is recommended both for diagnosis and to identify co-inherited pathogenic variants (e.g., LMNA, MYH7) that influence prognosis and trial-specific eligibility.
  • Anticoagulation status and thromboembolic history are relevant to trial safety criteria; report all prior embolic events and current anticoagulation therapy.
