Prenatal diagnosis of a right coronary artery to right atrial fistula with a giant coronary artery aneurysm: A case report

Coronary artery fistula (CAF) is a rare cardiac anomaly. Here, we diagnosed a right coronary artery-right atrium fistula with giant coronary artery aneurysm (CAA) via fetal echocardiography at 35 weeks' gestation. An urgent caesarean delivery was performed at 36 weeks' gestation because CAA caused mitral obstruction, and fetal atrial flutter was present. Following delivery, we performed aneurysm ligation because the new-born developed atrial tachycardia. The intraoperative findings confirmed the sonographic findings. To the best of our knowledge, prenatal ultrasound diagnosis of CAF and giant CAA has not been reported in the literature. We focus on the ultrasonic characteristics and differential diagnosis in this literature.

Prenatal diagnosis of left coronary artery to right ventricle fistula

Prenatal diagnosis of a congenital coronary artery fistula between the left coronary artery and the right ventricle was established at 28 weeks of gestation. Hydrops fetalis developed during follow‐up and the baby died on the first day after delivery. It is rare for coronary artery fistulas to become symptomatic during fetal life. © 2014 Wiley Periodicals, Inc. J Clin Ultrasound, 43 :129–131, 2015     

A case of coronary artery fistula diagnosed in the right decubitus position by transthoracic echocardiography

A 70-year-old woman was admitted to our hospital for a continuous heart murmur in the fourth intercostal space at the right sternal border. Routine echocardiography demonstrated aneurismal dilatation at the origin of right coronary artery. These findings suggested a coronary artery fistula, although its drainage site could not be identified. By shifting the patient to the right decubitus position, we could observe an abnormal color Doppler signal going from the right coronary artery into the right atrium, confirming coronary artery fistula. The right decubitus position may be helpful for the evaluation of abnormal anatomic and auscultatory findings.

A case of coronary-pulmonary artery fistula with coronary artery aneurysm detected for Kawasaki disease remote phase

Follow-up echocardiography showed two coronary-pulmonary artery fistulae and a coronary artery aneurysm in a 12-year-old boy who had been diagnosed with Kawasaki disease without persistent coronary artery lesion at the acute phase when he was 6-months-old. Left coronary arteriogram confirmed the fistulae and the 4.3 × 6.3 mm aneurysm. Results show that the fistula is associated with Kawasaki disease.     

Left atrial catheter ablation promotes vasoconstriction of the right coronary artery

Background: Multiple cardiac ganglia are present in the left atrial (LA) region, and marked changes in autonomic nervous activity can occur after left atrial catheter ablation (CA) for atrial fibrillation (AF). Vasospastic angina involving the inferior wall of the left ventricle has been reported as a complication shortly after LACA. Methods: We studied 20 patients with drug‐refractory AF who underwent LACA, performed to encircle the left‐ and right‐sided pulmonary veins, 1 to 2 cm from their ostia under fluoroscopic guidance. Quantitative coronary angiography was performed before and after LACA, and we analyzed the minimal lesion diameter (MLD) of the proximal segment of the coronary arteries, and the basal tone, the baseline percent constriction versus maximal dilation after nitroglycerin administration. Results: No significant difference was observed in MLD or basal tone of the left coronary arteries after LACA. However, in the right coronary artery (RCA), the basal MLD was smaller (P < 0.01) and the basal tone was greater (P< 0.05) after than before LACA. No correlation was found between the baseline MLD or tone of the RCA and total amount of radiofrequency energy delivered or procedure duration. In 75% of RCA, the baseline MLD was smaller after than before LACA, which was significantly higher (P < 0.01) than observed in the left coronary arteries (38%). Conclusion: Vasoconstriction was promoted in the RCA shortly after LACA, which may explain the variant angina reported after LACA.
