A novel area of compression over the left sternal border at the inter-nipple line would result in compressions over the LV in nearly three-quarters of our study participants.

Future research should investigate whether this proposed area of compression is applicable to a broader population including those with cardiac and thoracic disease.

The LV was located along the left sternal border in 62 (96.9%) participants.

The most frequent LV location was along the left sternal border at the sixth ICS in 26 (40.6%) participants, with 13 (20.3%) at the fifth and 10 (15.6%) participants at the seventh ICS.

In two (3.1%) participants, the LV was found along the mid-clavicular zone at the fifth ICS.
