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. Comparing those with LVES noncompacted-to-compacted ratio ≥2, those with LVES noncompacted-to-compacted ratio <2, and the normal control group, adjusted means for RV apical trabecular thickness and RVED noncompacted-to-compacted ratio were generated. Logistic regression was used to evaluate the association of composite events traditionally associated with LVNC with RVEF after adjustment for aforementioned covariates, cardiovascular risk factors, delayed enhancement, LVEF, and LVES noncompacted-to-compacted ratio. Analysis of RV morphology found greater apical trabecular thickness among those with LVES noncompacted-to-compacted ratio ≥2 compared with those with LVES noncompacted-to-compacted ratio <2 or normal control group (31 ± 5 vs 27 ± 2.6 vs 22 ± 4 mm; p = 0.03 and p = 0.003, respectively). There was no difference between the groups in relation to the RVED noncompacted-to-compacted ratio. Low RVEF and LVES noncompacted-to-compacted ratio ≥2 had significant association with clinical events in this population even after adjusting for clinical and imaging parameters (p = 0.04 and p <0.001, respectively). In conclusion, RV dysfunction in a morphologic LVNC population is strongly associated with adverse clinical events. LVNC is associated with increased trabeculations of the RV apex.

- Speckle-tracking echocardiographic imaging of the right ventricular systolic and diastolic parameters in chronic exercise.
- Simsek Z1, Tas MH, Gunay E, Degirmenci H.Author information 1Department of Cardiology, Faculty of Medicine, Ataturk University, Erzurum, Turkey. ziyamposta@hotmail.comAbstractMorphology and functions of the right ventricle (RV) show differences in the athletes based on whether exercising acutely or chronically. Temporary RV dysfunction occurs during acute exercise. However, RV functions during chronic exercise are speculative. In the present study, we aimed to evaluate RV functions of long-distance runners, who perform chronic exercise, by both conventional and speckle-tracking echocardiography. In this study, we examined 44 long-distance runner and 30 sedentary subjects. RV longitudinal strain (LS), RV systolic longitudinal strain rate (LSRs), RV early diastolic longitudinal strain rate and late diastolic longitudinal strain rate parameters were evaluated by apical 4-chamber gray-scale imaging through the septum and free wall of RV in accordance with automated function imaging protocol. It was observed on the conventional echocardiographic parameters of longdistance runners that RA and RVED diameter have been increased (p = 0.028; p = 0.003 respectively), whereas systolic right ventricle fractional area change and tricuspid annular plane systolic excursion values were similar to those of sedentary subjects (p = 0.65; p = 0.75 respectively). LS and systolic and diastolic strain rate functions were also similar. Morphological adaptation, but not functional change, occurs in the athletes performing chronic exercise.
