1/19. Coronary-to-bronchial artery communication: report of two patients successfully treated by embolization.

    We report two cases of coronary-to-bronchial artery communication responsible for coronary steal. In both cases the anastomosis originated from the proximal circumflex artery and developed because of bronchiectasis. In both cases closure of the anastomosis was achieved successfully by embolization. To date, the patients remained free from symptoms.

2/19. Local pulmonary malformation caused by bilateral coronary artery and bronchial artery fistulae to the left pulmonary artery in a patient with coronary artery disease.

    At 10 years of age and again at 25, our patient had been treated for pulmonary tuberculosis due to the presence of a localized pulmonary shadow. coronary angiography at age 59 revealed 3 fistulous communications: from the right and circumflex coronary arteries and from the left bronchial artery. All 3 emptied into the same recipient artery, the distal part of a left pulmonary artery branch, which produced substantial left-to-right shunt. On computed tomography, cystic formations could be seen in the pulmonic area. The pulmonary tuberculosis for which this patient had been treated in his youth was in the same part of the lung where the shunt was discovered. Our conclusion is that the initial diagnosis was in error.

3/19. Allograft aortic root replacement for aortic valve endocarditis with aortopulmonary fistula.

    Acute infective endocarditis affecting the aortic root and valve associated with development of a fistulous communication between the aorta and pulmonary artery was presented in a young Turkish girl. Emergency surgery was required. Operation consisted initially of closure of the defect on the main pulmonary artery with a pericardial patch. This was followed by allograft aortic root replacement.

4/19. chondroblastoma of the temporal bone associated with a persistent hypoglossal artery.

    A case of a chondroblastoma of the skull-base associated with a persistent hypoglossal artery (PHA) is presented. Neuroradiological findings of the PHA and the tumour are reported. The existence of a carotico-basilar communication such as a PHA should be recognized prior to skull base surgery because of the potential risk of cerebral ischemia.

5/19. Ruptured pseudoaneurysm of aortic root graft into the pulmonary artery as a cause of severe heart failure.

    A 52-year-old man presented with heart failure of 1 month duration. He had undergone aortic valve and root replacement 30 months before admission. A continuous murmur was heard in the second intercostal space at the parasternal border. aortography showed a pseudoaneurysm surrounding the aorta, whereas color Doppler study revealed flow from the central aorta to the pseudoaneurysm and flow from the pseudoaneurysm to the pulmonary artery trunk through a fistulous communication between them. Thus, fistulous communication with pulmonary artery causing heart failure is a complication of pseudoaneurysm after aortic and root replacement, which can be diagnosed clinically and echocardiographically.

6/19. Acquired aortopulmonary fistula.

    An acquired aortopulmonary artery fistula is rare. We describe a case with an aortic arch aneurysm communicating with the main pulmonary artery. The diagnosis was made on the basis of transthoracic echocardiography and confirmed by transesophageal echocardiography. A post-mortem examination revealed the complete anatomy of the aneurysm and the aortopulmonary communication.

7/19. Chronic posttraumatic aneurysm of descending aorta with fistulous communication into pulmonary artery.

    We report an unusual case of presumed posttraumatic chronic proximal descending aneurysm associated with a fistula into the pulmonary artery. review of the literature showed that a fistula of the descending aorta into the pulmonary artery is uncommon and that only a few patients have survived. This rare entity is best treated with open repair; however, in patients at high risk an endovascular stent graft is an option.

8/19. Coronary arterial malformation depicted at multi-slice CT angiography.

    We present a case of a 57-year-old woman with an unremarkable medical history except for a continuous cardiac murmur at the left second and third interspaces. Transthoracic echocardiography revealed an unusual chamber in front of the heart. To evaluate the precise anatomy of this abnormality, multi-slice computed tomographic (MSCT) imaging was performed. MSCT angiography with retrospective ECG gating showed a coronary arterial malformation with fistulous communications to the coronary artery, pulmonary artery and the root of aorta. Images from MSCT coronary angiography can be helpful in understanding the tortuous configuration of the coronary arterial malformation.

9/19. Congenital aneurysm of the left coronary sinus and left main coronary artery with fistulous communication to the right atrium in pregnancy.

    We describe a unique case of a left coronary arteriovenous fistula arising from a left sinus of valsalva aneurysm in a pregnant woman. The relevant diagnostic contributions of two-dimensional echocardiography, color flow Doppler, magnetic resonance imaging, and angiography are discussed. The hemodynamic manifestations of this anomaly in pregnancy and the eventual surgical correction are reviewed.

10/19. Doppler echocardiographic findings in coronary-pulmonary fistula.

    We describe a patient with a coronary-pulmonary fistula who had a syncopal attack. He had also pectus excavatum. Doppler echocardiography revealed late diastolic flow in the left high parasternal region which was not caused by pulmonary insufficiency, but by the jet through the fistulous communication. Selective coronary angiography demonstrated the fistula between the left anterior descending artery and the pulmonary trunk.
