1/82. Intralobar pulmonary sequestration supplied by the right coronary artery.

    Bronchopulmonary sequestrations are malformations that are often congenital; they consist of isolated nonfunctioning lung segments having no communication with functional tracheobronchial elements of the surrounding lung. They are supplied by single or multiple branches from the distal thoracic or proximal abdominal aorta, or from the celiac, splenic, intercostal, subclavian, or pulmonary artery. Due to the absence of ventilation, the lung tissue can become chronically infected. We describe an intralobar pulmonary sequestration with arterial supply from the right coronary artery.

2/82. 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.

3/82. Multiple spontaneously occurring coronary artery-left ventricular communications: a case report.

    A search of the literature revealed that spontaneous coronary artery-left ventricular communications have only rarely been reported. These fistulae are frequently associated with angina pectoris which has been attributed to a ventricular steal phenomenon. The patient described herein presented with angina pectoris and was found to have multiple coronary arterioventricular communications without significant coronary atherosclerosis.

4/82. Right ventricular thrombosis early after bidirectional Glenn shunt.

    thrombosis in the right ventricle occurred early after bidirectional superior cavopulmonary shunt in 2 patients with pulmonary atresia with intact ventricular septum and major right ventricular coronary artery communication, and perioperative brain infarction occurred in 1 patient. Clinicians should be aware of the hazards of this potentially lethal complication, and transfusion of platelets and fresh plasma should be minimized. Although the hemodynamic state is good, echocardiography should be performed frequently and strict anticoagulation should be started as early as possible.

5/82. Divided left atrium associated with supravalvar mitral ring.

    Reported is a case with a rare association of divided left atrium, supramitral stenosing ring of the left atrium, connection of the left superior caval vein to the roof of the left atrium, unroofed coronary sinus with an interatrial communication at the mouth of the unroofed sinus and ventricular septal defect. The need for a complete echocardiographic examination in the presence of pulmonary venous obstruction is emphasized. Surgery was successful in spite of significant preoperative pulmonary hypertension.

6/82. pulmonary atresia with intact ventricular septum, antegrade coronary-right ventricular sinusoidal communication, and wolff-parkinson-white syndrome.

    A fenestrated Fontan operation was performed successfully in a patient with pulmonary atresia with intact ventricular septum, an antegrade sinusoidal communication, and wolff-parkinson-white syndrome. Unlike most cases, blood flow in the sinusoidal communication was antegrade, from the left anterior descending artery to the right ventricle. This is the first report of the combination of pulmonary atresia with intact ventricular septum and wolff-parkinson-white syndrome.

7/82. Non-invasive diagnosis and management of coronary arteriovenous fistula. A case report.

    Coronary arteriovenous fistulas are rare anomalies resulting in abnormal communication between the coronary artery and any chamber of the heart. An asymptomatic patient was referred for evaluation of her murmur. Two-dimensional and color Doppler echocardiographic evaluation revealed an enlarged left main coronary artery. A retrograde, eccentric small jet was found within the right ventricular outflow tract at the pulmonary artery valvular level allowing us to detect the entrance site of the fistula. The diagnosis was confirmed by cardiac catheterization and angiocardiography. Although our case was asymptomatic, the decision to perform cardiac surgery was made because of the aneurysmatic appearance of the left coronary artery. In our opinion, visualization of coronary arteries by two-dimensional echocardiography, together with additional information obtained from the Doppler examination, provides an excellent technique for the noninvasive diagnosis of coronary artery fistula.

8/82. Multiple coronary arteriovenous fistulae.

    A case with multiple congenital coronary arteriovenous fistulae is reported. The right coronary artery was communicating with the right ventricle. The left coronary artery was entering directly into the pulmonary trunk and two terminal branches of the anterior descending into the left ventricle. The direct communication of the left coronary artery without interposition of an accessory artery or a circoid plexus is met for the first time.

9/82. Diffuse multiple coronary arteries to left ventricular fistulas.

    Coronary artery to left ventricular fistula is an unusual anatomic anomaly consisting of a communication between one of the coronary arteries and the left ventricle. Only sporadic cases have been published in the literature. Diffuse multiple fistulas involving both left and right coronary arteries are even rarer. This report describes a 60-year-old woman with diffuse multiple fistulas communicating between both coronary arteries and the left ventricle. The patient manifested clinically with exertional angina and myocardial ischemia, as evidenced by a positive stress exercise test, which represents the coronary "steal" phenomenon.

10/82. 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.
