Abstract:
Congential aorta-right atrial tunnel (ARAT) is a rare anomaly. Many patients are asymptomatic and diagnosis can be made during investigation of systolic and diastolic continuous murmur heard on cardiac oscultation. In some patients, symptoms such as palpitation, dyspnea, and fatigue on exertion can be seen. With transthoracic and transesophageal echocardiography diagnosis can usually be made, but more definite diagnosis is possible with coronary angiography, aortography, and computerized tomography. Herein with the data from current literature we will discuss a case who was admitted to our clinic with symptoms of heart failure and diagnosed with ARAT.
