Patients affected by this deformity should ask for an appointment for a clinical evaluation. The diagnostic tests for Pectus Exacavatum tend to include computed tomography (CT), pulmonary function (spirometry) and cardiac (electrocardiogram and echocardiogram) tests.sintomatologia-1

The CT is used to measure the Haller Index, i.e. the connection between the transverse diameter (the horizontal distance within the chest cavity) and the anteroposterior diameter (the shortest distance between the vertebrae and the sternum) at the point of maximum chest depression. A Heller Index that is equal to or greater than 3.25 is defined as severe and may be an indicator for surgical treatment of Pectus Excavatum.
