Right ventricular morphology and systolic function in left ventricular noncompaction cardiomyopathy
Stacey R, Andersen M, Thohan V, et al. Right ventricular morphology and systolic function in left ventricular noncompaction cardiomyopathy. The American Journal Of Cardiology. March 15, 2014;113(6):1018-1023.
The distinction between normal right ventricular (RV) trabeculations from abnormal has been difficult. We evaluated whether RV volume and function are related to left ventricular (LV) noncompaction (NC) cardiomyopathy and clinical events. Trabeculations or possible LVNC by cardiac magnetic resonance imaging was retrospectively observed among 105 consecutive cases. We measured LV end-systolic (ES) noncompacted-to-compacted ratio, RV ejection fraction (EF), RV apical trabecular thickness, and RV end-diastolic (ED) noncompacted-to-compacted ratio. A control group of 40 subjects was also reviewed to assess the exploratory measures.
