Abstract: A case of quadricuspid aortic valve is described. The aortic valve consisted of 3 equal-sized and 1 smaller cusps, and a supernumerary cusp located between the right and noncoronary cusps. A right coronary ostium was close to the accessory commissure, and in a lower position. Three fenestrations were found at the supernumerary commissure. Aortic valve replacement was performed successfully with a St. Jude Medical prosthetic valve. On histological examination, the resected cusps showed fibrotic thickening with … Show more

“…From the surgical standpoint, it is important to recognize any displacement of the coronary ostia to prevent ostial obstruction of the coronary artery when fixing the prosthetic valve ring. 7 Therefore the anatomy of the heart, especially that of the coronary arteries, must be carefully evaluated in patients with a QAV before surgical intervention to prevent serious complications.…”

“…Many cases report a downward displacement of a coronary orifice towards the annulus and this has been associated with occlusion of the vessel by a prosthetic valve sewing ring following valve replacement surgery for severe aortic regurgitation. 2 Multidetector coronary CT angiography offers a single, noninvasive test that can accurately classify the valvular anatomy, assess the degree of regurgitation by measurement of anatomical regurgitant orifice, measure displacement of the coronary ostia above the annulus and identify high risk anomalous coronary anatomy.We present images from a young sportsman (diagnosis made by transthoracic echocardiogram) who fortunately, did not exhibit significant displacement or anomaly (figure 1 and see online supplemental images). …”
