Aneurysm of the right sinus of Valsalva dissecting into the interventricular septum, submitral aneurysm and left ventricular non-compaction: three rare diseases in the same patient.

A 24-year-old black man presented to the emergency department of our hospital with fatigue and dyspnea at rest of two weeks duration. The transthoracic echocardiogram (Figure 1) revealed aneurysm of the right sinus of Valsalva (Figure 1A) dissecting into the interventricular septum (arrow) (Figure 1B), dilated left ventricle with moderately to severely impaired systolic function, and echocardiographic criteria for left ventricular non-compaction (Figure 1C and D). A submitral aneurysm and a dilated left atrium were also observed (Figure 1C). Doppler echocardiography showed mild mitral and aortic regurgitation. Multislice computed tomography with contrast (Figure 2) revealed an aneurysm of the right sinus of Valsalva (Figure 2A) dissecting into the interventricular septum (arrow) (Figure 2B), as well as a submitral aneurysm (Figure 2C) and non-compaction of the left ventricle (Figure 2D), confirming the echocardiographic findings. The patient was admitted to the cardiac intensive care
