Long-term follow-up of 34 adults with isolated left ventricular noncompaction: a distinct cardiomyopathy with poor prognosis
Key result
Isolated ventricular noncompaction carries a ~53% risk of incident heart failure alongside high mortality and arrhythmias.
- n=34
Why the study?
Knowledge regarding diagnosis, morbidity, and prognosis of isolated ventricular noncompaction (IVNC) is limited.
Population
34 adults with isolated ventricular noncompaction, age >16 years, 25 men
Design
Prospective cohort study using echocardiographic diagnostic criteria
Follow-up
44 + 40 months

Implication
Long-term cohort study demonstrates poor clinical prognosis in adults with isolated left ventricular noncompaction, highlighting the need for vigilant management of severe cardiac complications.
Key Points
- To evaluate the long-term clinical progression, complications, and overall prognosis of adult patients diagnosed with isolated left ventricular noncompaction.
- Long-term observational follow-up study evaluating clinical outcomes in a cohort of 34 adult patients (N=34) diagnosed with isolated left ventricular noncompaction.
- Isolated left ventricular noncompaction presents as a distinct form of cardiomyopathy associated with a persistently poor long-term prognosis.
- Adult patients with this condition face substantial long-term cardiovascular morbidity and a high incidence of adverse cardiac events.

Cite This Study
Oechslin et al. (2000) conducted a cohort in Isolated ventricular noncompaction (n=34). Isolated ventricular noncompaction was evaluated on Morbidity and mortality (heart failure, thromboembolic events, ventricular tachycardias, death). In a prospective cohort of 34 adults with isolated ventricular noncompaction, 53% developed heart failure, 41% had ventricular tachycardias, and 35% died over a mean follow-up of 44 months.
