Abstract:
Objective To explore the value of echocardiography on diagnosis and differential diagnosis of aortico-left ventricular tunnel(AOLVT).Methods Echocardiographic features of 9 patients with AOLVT were reviewed and analyzed.The diagnosis methodology was summarized;the reasons for missed diagnosis and misdiagnosis by echocardiography were analyzed.Results Among 9 patients with AOLVT,one was diagnosed through CT examination prior to the operation and died from the cardiac arrest.The others all received the surgical operation and were diagnosed as AOLVT.Five patients were accurately diagnosed by echocardiography prior to the operation,4 patients were misdiagnosed,in which 3 patients were diagnosed as aortic valve regurgitation,one patient was diagnosed as aortic dissecting aneurysm.The diameter of left ventricle(LV)decreased and LV ejection fraction increased distinctively for 7 operated patients(P＜0.001)in six months after operation.Only one operated patient failed to recover from the LV dysfunction and died of aortic valve perivalvular leak in two monthes.Conclusions The diagnosis of the AOLVT mainly depends on the echocardiography.By enhancing the understanding on such disease and investigating on the structure and hemodynamics will be contributive to the accurate diagnosis of echocardiography.
