Ventricular dysfunction and number of non compacted segments in non compaction: non-independent predictors

Int J Cardiol. 2010 Jun 11;141(3):250-3. doi: 10.1016/j.ijcard.2008.11.199. Epub 2009 Feb 11.


Background: Isolated ventricular noncompaction (IVNC) is characterized by multiple prominent trabeculations and deep intertrabecular recesses. Some reports prove that the chronic heart failure may occur in approximately half of the patients. In this report we investigate the correlation between the number of non compacted segments and entity of systolic dysfunction from the registry and subregistries of the SIEC.

Method: To identify the correlation between ventricular dysfunction and number of segments involved in non compaction we evaluated a consecutive series of 238 patients affected by non compaction, from the SIEC (Società Italiana di Ecografia Cardiovascolare) registry. The average age of patients was 41.5 years (range: 1-92 years), 137 were males and 101 females. In 122 cases we found ventricular systolic dysfunctions with an EF average of 34.6%. The number of affected segments by non-compactation and diastolic dysfunction were found to be non-independent predictors of LV systolic dysfunction.

Conclusion: From the analyses we carried out, it seems that ventricular dysfunction seems to be completely independent from the segment numbers of non compacted segments.
