The abnormalities of the Sinus of Valsalva are characterized into three different groups: (1) unruptured aneurysm of the Sinus of Valsalva, (2) aneurysm of the Sinus of Valsalva with intracardiac or extracardiac rupture, and (3) intracardiac or extracardiac fistula of the Sinus of Valsalva.<a class="elsevierStyleCrossRefs" href="#bib0050"><span class="elsevierStyleSup">1,5</span></a></p><p id="par0040" class="elsevierStylePara elsevierViewall">Meyer and colleagues<a class="elsevierStyleCrossRef" href="#bib0050"><span class="elsevierStyleSup">1</span></a> made a survey about the procedures realized at the Texas Heart institute from April 1956, to September 1973. They found 45 patients with aneurysm and/or fistula of the Sinus of Valsalva, representing 0.43% of all procedures which were required cardiopulmonary bypass. Of the 45 patients in the group, 22 had an unruptured aneurysm, whereas 10 and 13 had a ruptured aneurysm and a simple fistulous communication, respectively. On the other hand, according to Walpot and contributors<a class="elsevierStyleCrossRef" href="#bib0075"><span class="elsevierStyleSup">6</span></a> and Nishi et al.,<a class="elsevierStyleCrossRef" href="#bib0070"><span class="elsevierStyleSup">5</span></a> the major cause of an aorto-cardiac fistula is a rupture of an aortic sinus aneurysm, accounting for 76% of the cases.</p><p id="par0045" class="elsevierStylePara elsevierViewall">Many patients can be asymptomatic, but the typical symptoms are like Congestive Heart Failure (CHF). A pain in the chest and a sudden onset of the symptoms point to a ruptured aneurysm. It is possible to hear a “to-and-fro” murmur on cardiac auscultation with a systolic and diastolic thrill. The diagnosis is usually taken by transthoracic or transesophageal echocardiography, cardiac catheterization with aortography, computed tomography or magnetic resonance imaging (MRI), revealing a left-to-right shunt.</p><p id="par0050" class="elsevierStylePara elsevierViewall">It is important to differentiate the ARVF from the Aorto-Right Ventricular Tunnel (ARVT). This condition, as the first, communicates the aorta to the right ventricle, however the second one's perforation arises above the sinutubular junction instead and runs into extra-cardiac tissues addressed to ventricular chambers, forming a conduit that by-passes the sinutubular junction. According to McKay et al.,<a class="elsevierStyleCrossRef" href="#bib0085"><span class="elsevierStyleSup">8</span></a> the origin of the tunnel from the ascending aorta serves to differentiate it from rupture of an aneurysmal Sinus of Valsalva. Most part of the aorto-ventricle tunnel communicates the aorta to the left ventricle (90%), and just a small part of the cases do to the right ventricle.<a class="elsevierStyleCrossRef" href="#bib0090"><span class="elsevierStyleSup">9</span></a> In the other hand, some surgeons consider that apart from fistulae secondary to infection, trauma or post surgical, most cases are a manifestation of a ruptured Sinus of Valsalva. While some authors use the term aorto-ventricular tunnel, others say that these terms are sinonimous and do not correspond to a different pathology. In their opinion the right term is ruptured Sinus of Valsalva. In the ARVF, the communication is localized below the sinutubular structure, where the abnormal pathway remains completely within the heart.<a class="elsevierStyleCrossRef" href="#bib0085"><span class="elsevierStyleSup">8</span></a></p><p id="par0055" class="elsevierStylePara elsevierViewall">The surgical correction is the treatment of choice.
