Table 1: Classification of sinus of

Valsalva aneurysms proposed by Sakakibara and Konno.

Type I

Connects the right sinus of Valsalva and the right ventricular outflow tract below the pulmonary valve

Type II

Connects the right sinus of Valsalva and the right ventricle at the crista supraventricularis

Type III

IIIa

Connects the right sinus of Valsalva and the right atrium

IIIv

Connects the posterior area of the right sinus of Valsalva and the right ventricle

IIIa+v

Connects the right sinus of Valsalva to both the right atrium and the right ventricle

Type IV

Connects the non-coronary sinus of Valsalva and the right atrium
