Dr. Jagroop S. Saran, Toronto General Hospital, University Health Network, University of Toronto, Canada, e-mail: jagroopsaranmd@gmail.com Dear Editor,

Quadricuspid aortic valve (QAV) is an extremely rare congenital cardiac defect with an estimated incidence of 0.01–0.05% based on autopsy and echocardiography databases [1]. It is usually an isolated defect but can be associated with other congeni- tal heart abnormalities including al- tered coronary artery anatomy and coronary ostium abnormalities, atrial or ventricular septal defects, patent ductus arteriosus, subaortic stenosis, pulmonary valve stenosis, mitral valve prolapse, and hypertrophic cardiomy- opathy. It may also coexist with aortic dilatation of the aortic root and/or ascending aorta. The most common functional consequence is purely re- gurgitation although it may present as mixed stenosis/regurgitation.

Patients with isolated QAV are typically asymptomatic until the fifth or sixth decade of life [2]. Surgical in- tervention is indicated for severe aor- tic regurgitation or stenosis or a dys- functional QAV associated with other

lesions, particular coronary artery or ostia abnormalities. It is also recom- mended for asymptomatic patients with decreased left ventricle (LV) systolic function (LV ejection fraction

< 50%) or enlargement (LV end sys- tolic diameter > 55 mm or LV end dia- stolic diameter > 75 mm) [3].

Transesophageal echocardiog- raphy can demonstrate aortic valve morphology including cusps, coapta- tion defects, aortic root and ascending aorta dimensions, and severity of re- gurgitation. The aortic valve, seen in- traoperatively in the mid esophageal aortic valve short axis view, in dias- tole, reveals the four cusps (Figure 1).

The QAV consists of three equal size cusps and one smaller supernumer- ary cusp located between the left and noncoronary cusps in the 10 o’clock position consistent with the type B classification proposed by Hurwitz and Roberts [3].
