Isolated and associated non-compaction of the left ventricle is an uncommon cardiomiopathy, with an unclear natural history.13 Some authors described a bad prognosis for this disease.1,2 Instead, other published works, such as the Lilje's1 work published in European heart journal in August, with a longer follow-up and with a larger cohort, reported a medium-long term good prognosis. Correlated with the prognosis is the ventricular dysfunction.
During this last year, we collected more than 230 patients in the Italian society of cardiovascular ultrasound registry. The incidence of chronic heart failure (EF < 45%) in our experience was around 50%. However, an important bias influences these data: all patients enrolled in a hospital division, where, in a large percentage, were admitted for symptoms. So the analysed population is a selected population. To demonstrate this hypothesis, we studied all first-degree relatives of 31 patients. In total, we observed 48 relatives affected by non-compaction. Of the total patients, 61% (19/31) presented an EF reduction, whereas of the relatives, only 2% (1/48) presented an EF reduction.
In our opinion, high incidence described by Lilje et al.1 of ventricular dysfunction is a consequence for a selected cohort.
