Straight Back Syndrome; A Misleading Condition in Cardiology, Demonstrated with Magnetic Resonance Imaging

Main Article Content

Lertlak Chaothawee, MD


Straight back syndrome (SBS) is a deformed thoracic spine disease sometimes considered as a pseudo-heart disease because its pathology can prominently affect the normal function of the heart system. SBS patients often present with signs and symptoms that are similar to some cardiac diseases that hide those of the thoracic spine.1,2 Consequently, SBS has become the one of the most common misleading conditions in cardiology. Investigations for SBS are frequently performed in patients with an abnormal systolic murmur with no evidence of any cardiac-related cause. This article will detail the importance of the straight back syndrome in diagnostic cardiology and demonstrate a case with Magnetic Resonance Imaging.
