This study was conducted to determine the diagnostic value of stress echocardiography squatting as a non-invasive examination of a relatively simple, inexpensive, and safe in the detection of coronary artery stenosis in stable CHD and unstable angina patients. Methods: This study was a cross-sectional design. The subjects were all patients with stable CHD and unstable angina whom were treated in Instalasi Pusat Jantung Rumah Sakit Dr. M. Djamil Padang from May to July 2016. Subjects underwent squatting stress echocardiography procedures followed by coronary angiography. Diagnostic test was used to determine the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of squatting stress echocardiography. Results: The sensitivity, specificity, and accuracy of squatting echocardiography for diagnosis of CAD were 90.3%, 88.9% and 89.7%, respectively. Conclusion: Squatting stress echocardiography can be proposed as a non-invasive examination which is relatively simple, inexpensive and safe to detect coronary artery stenosis on patients with stable CHD and unstable CHD.

A coronary fistula can produce high-output heart failure from volume overload and/or myocardial ischemia from coronary steal phenomenon. A 35-year-old man was found to have a large fistula from the left circumflex coronary artery to the SVC-right atrium junction, an extremely rare anomaly. This patient developed right ventricular dysfunction and chest pain due to myocardial ischemia in the left circumflex coronary artery distribution for several months before evaluation. Because of the large size of the fistula, surgical ligation was chosen instead of coil embolization to close the fistula. The patient was free of chest pain postprocedure. Coronary artery fistulas, though rare, should be considered in the differential diagnosis when a young patient presents with chest pain and/or heart failure. V
