In this clinical example, the difference is more subtle and is also related to a view more tilted towards the 5-chamber view (Figure 26), compared to the optimized 4-chamber view (Figure 27). The LV long axis was 8.3 cm in the 5-chamber and 9 cm in the 4-chamber view.

In conclusion, obtaining a correct LV geometry is one of the most important tasks in echocardiography, but it is too often overlooked, even by senior operators. The clinical impact of this superficial approach to the echocardiographic examination can have a significant clinical impact, not to mention the potential disruptive effect on clinical research.
