734 do NORRE (Normal Reference Ranges for Echocardiography)


Patient population

A total of 865 normal European subjects were enrolled at 22 echocardiographically accredited collaborating European institutions. After exclusion of patients (n = 131) due to incompatible image format, poor image quality, high body mass index/abnormal glycaemia values, cardiac pathology detected by echocardiography, the final study population consisted of 734 healthy subjects with a mean age of 45.8 ± 13.3 years (range: 20–78).


The NORRE study provides useful two-dimensional echocardiographic reference ranges for cardiac chamber quantification. These data highlight the need for body size normalization that should be performed together with age-and gender-specific assessment for the most echocardiographic parameters.

For these reasons, the current BSE reference intervals were in large part derived from the NORRE dataset.

In conclusion, in addition to providing higher resolution and uninterrupted procedural guidance, the use of TEE with MAC during TAVR is associated with a lower fluoroscopic time, a lower need for additional aortograms and trend in lower post-TAVR AKI. These findings can be utilized when assessing the optimal periprocedural imaging strategy in patients undergoing TAVR
