Highlights a rare presentation of cardiogenic shock caused by severe acute aortic regurgitation due to an idiopathic anterior leaflet perforation.
Idiopathic leaflet perforation can cause acute AR with cardiogenic shock; leaves open broader etiologies for targeted investigation.
Aortic regurgitation (AR) is grouped into acute or chronic AR. Acute AR, unlike chronic AR, can manifest with significant hemodynamic compromise. Acute AR is typically due to endocarditis or aortic dissection, and less commonly due to blunt trauma or iatrogenic causes. We present a patient with cardiogenic shock due to severe acute AR from anterior leaflet perforation without an identifiable rheumatologic or infectious etiology.
