Reclassification of LV geometric patterns in morbidly obese patients. A CRM study

The echocardiographic definition of LV geometric pattern has limitations in terms of accuracy and reproducibility of measurements and the geometric assumptions on LV geometry to calculate volume from linear dimensions. A Cardiac Magnetic Resonance- based volumetric analysis overcomes the limitation of the use of linear parameters to calculate volume and is higly reproducible. Objective: Comparison of LV pattern in morbidly obese patients by echocardiography and CMR. Methods: 37 morbidly obese patients underwent echocardiography and CMR. Results: CMR- LVmass index was lower than echo- LV mass index and LVmass/Volume ratio was normal (table, figure). Table 1. Patient characteristics, echo and CRM data in morbidly obese patients (n=37) Data are expressed as mean (SD). **Denotes p<0.05. Figure 1. LV geometric pattern by Echo vs CRM Conclusions: In morbidly obese patients, CMR reclassifies most abnormal echo-based LV patterns into normal. Ecccentric remodeling is more common than concentric with either Echo or CMR.
