Abstract:
Objective To summary the echocardiographie features of the patients with dissection into interventricular septum (IVS) and to analyze the etiology.Methods The data of 13 cases with the dissection into the interventricular septum diagnosed by echocardiography were reviewed to summarize the echocardiographic features and the analysis of etiology.Results Among the 13 patients with dissection into IVS,11 patients were dissected into IVS from the right sinus of Valsalva (SOV),in which 5 patients were from single aneurysm of the right SOV,one patient was from a combination of a bicuspid aortic valve and right SOV,4 patients were from aortic valve infection of infective endocarditis,and one patient was induced by severe paravalvular leak after mechanical aortic valve prosthetic replacement was complicated by annular detachment.In all 11 patients,eehocardiography showed a dissecting cystic-like mass in the IVS from the base to mid septum or confined to the septal base.The path of the dissection in all these patients was traced to the right SOV.In the other 2 patients,IVS dissection followed septum rupture due to a myocardial infarction.Conclusions Echocardiography could accurately diagnose dissections of the IVS and to analyze the etiology,which is very helpful to make the clinical medical strategy.
