Abstract
Pneumothorax is a frequent problem in the intensive care unit. Lung ultrasound has demonstrated to be a useful method in its diagnosis with high sensitivity and specificity. The pattern observed in pneumothorax are the abolition of lung sliding and the lung point sign defined as an inspiratory-synchronized change from lung sliding to no lung sliding in a specific location on the chest wall in B and M-mode. We describe a case of pneumothorax diagnosed through a variant of the lung point sign at the left hemithorax: the heart point sign. 2 | CASE PRESENTATION
