This 49 year old male had been healthy but presented with increasing SOB. Below are the radiographs in the first 6 days in the hospital
A CT was done. Two representative images are below
The CT shows a sinus of valsalva aneurysm that is nearly completing obliterating the LA cavity approximately 4 cm, causing a pulmonary venous obstruction. See the enclosed echo report from SMH and a brief reference. echo-report-s-of-v s-of-v-cardiolgy
While I could find reports of S of V aneurysm causing Ra-RV inflow obstruction, I could not find a similar case of a LA obstruction as in this presentation. There are 3 sinuses of Valsalva, so it likely is that one is more susceptible to aneurysm formation but that is my own speculation.
