Echocardiography significantly overestimated left ventricular mass compared with cardiovascular magnetic resonance imaging (189.6±62.1 g vs 164.6±44.7 g; P<.0001) in children with hypertension.
Cross-Sectional (n=22)
Does cardiovascular magnetic resonance imaging improve the accuracy of left ventricular mass and hypertrophy assessment compared to echocardiography in children with hypertension?
In children with hypertension, echocardiography significantly overestimates left ventricular mass compared to CMR imaging, suggesting CMR may be a more accurate modality for assessing LVH in this population.

Cardiovascular magnetic resonance ( CMR ) imaging in adults is considered the gold standard for assessment of left ventricular mass ( LVM ) and left ventricular hypertrophy ( LVH ). The authors aimed to evaluate agreement of LVM measurements and LVH determination between echocardiography ( ECHO ) and CMR imaging in children with hypertension ( HTN ) confirmed by 24‐hour ambulatory blood pressure monitoring ( ABPM ). The children (n=22) underwent contemporaneous ECHO , CMR imaging, and ABPM. Patients had a mean body mass index of 30.9±7.5 (kg/m 2 ), and 81.8% had severe HTN . LVM measured by ECHO was 189.6±62.1 g and by CMR imaging was 164.6±44.7 g ( P <.0001). Bland‐Altman analysis revealed significant variability between ECHO and CMR imaging in the measurement of LVM . Interobserver error was higher with ECHO than with CMR imaging. ECHO had high sensitivity and low specificity in LVH determination. In conclusion, ECHO overestimates LVM and is less accurate in measuring LVM as compared with CMR imaging in children with HTN . Further prospective study using CMR imaging to assess LVM in children is warranted.
Supe‐Markovina et al. (Mon,) conducted a cross-sectional in Pediatric hypertension (n=22). Cardiovascular magnetic resonance (CMR) imaging vs. Echocardiography (ECHO) was evaluated on Left ventricular mass (LVM) measurement (p=<.0001). Echocardiography significantly overestimated left ventricular mass compared with cardiovascular magnetic resonance imaging (189.6±62.1 g vs 164.6±44.7 g; P<.0001) in children with hypertension.
