Surgical treatment of a pseudoaneurysm of mitral-aortic intervalvular fibrosa: Reply

摘要

First of all, we would like to mention that we are very proud because of the publication of our paper in your journal. Secondly, we read the "Letter to Editor" about our report with a great happiness. We are very thankful for the greetings which we received in that text. As the author mentioned in his letter, pseudoaneurysm of the mitral aortic intervalvular fibrosa is a rare condition that occurs at the fibrous body between the mitral and aortic valves (the mitral-aortic intervalvular fibrosa) which is a really important heart structure that was defined clearly and correctly in his letter to editor. Waldhausen and colleagues first described this anomaly in 1966. The most common etiologic factors are infective endocarditis and aortic valve surgeries.2 It is diagnosed by the presence of the eccentric jet from the opening of the aneurysmal sac in transesophageal echocardiographic views, and it can also be confirmed by cardiac computed tomography or magnetic resonance imaging. Mitral-aortic intervalvular fibrosa pseudoaneurysm can be asymptomatic or manifest itself with shortness of breath, palpitation, chest pain, or cerebrovascular accidents. It can also lead to heart failure. Fistula formation and coronary artery compression are the most frequent complications of mitral-aortic intervalvular fibrosa pseudoaneurysm. Fistulas into the left atrium and aorta are relatively common. Moreover, rupture into the pericardial space and pulmonary artery compression were also reported in some cases.
