Abstract Background We report a rare case of left ventricular inflow obstruction from a branch of the left circumflex coronary artery to the right atrium caused by a coronary arteriovenous fistula (CAVF) in a young Japanese male child. Case presentation The patient was diagnosed with CAVF following a heart murmur shortly after birth. The left-to-right shunt caused right ventricular volume overload and pulmonary congestion. An emergency surgical intervention was performed for the CAVF on day 6 after birth. However, by 5 years of age, his left ventricular inflow obstruction worsened. We found an abnormal blood vessel originating from the proximal part of a branch of the left circumflex coronary artery, circling the outside of the mitral valve annulus along the medial side of the coronary sinus. As the child gets older, the blood inflow into the left ventricle might get restricted further, resulting in left-sided heart failure. Conclusion Our findings suggest that even after CAVF closure surgery, it is essential to monitor for complications caused by progressive dilatation of a persistent CAVF.

Iatrogenic Coronary arteriovenous fistula (CAVF) is a rare complication of coronary intervention. Although acquired CAVF during percutaneous coronary intervention (PCI) of chronic total occlusion (CTO) has been reported, CAVF resulting from contrast injection into a right coronary artery (RCA) CTO during diagnostic coronary angiography is very rare.

Abstract Interestingly, our case presenting with coronary AV fistula firstly reported in the literature with fetal valproate syndrome. Although differential diagnosis is sometimes difficult, it can be diagnosed with detailed history, physical examination and appropriate laboratory tests. Fetal valproate syndrome can be prevented by discontinue of the valproic acid especially during first trimester of pregnancy.

Abstract Background Coronary artery aneurysms (CAAs) are uncommon, and giant aneurysms (>2 cm) are even more unusual. Coronary atherosclerosis and Kawasaki disease are the leading causes for this pathology. The treatment for this condition is controversial because the evidence is based on case report series. Case summary We describe the case of a 77-year-old female patient who presented with heart failure symptoms. She was diagnosed with a giant saccular aneurysm arising from the right coronary artery (RCA) ostium and a fistula between the RC and the left anterior descending artery (LAD) to the coronary sinus. And an atrial septal defect (ASD) and severe tricuspid regurgitation were also found. The patient underwent surgery through a medium sternotomy, the aneurysm was opened and resected under cardiopulmonary bypass. The RCA was ligated at the distal end of the aneurysm, and a saphenous vein graft bypass was performed. A coronary arteriovenous fistula from the distal portion of RC and LAD artery to a severely enlarged coronary sinus was found and corrected with an autologous pericardial patch. Closure of the ASD was performed with a pericardial patch and a tricuspid ring annuloplasty was done. Post-operative course was uneventful. Discussion There are few cases of giant coronary aneurysms associated with fistulas reported in the literature. Despite the endovascular percutaneous techniques available to treat these patients, we believe that surgical treatment was the best option for this particular case. We consider that surgical treatment is a very good option for giant CAAs associated with AV fistulas that are not susceptible for current endovascular available devices. The literature lacks evidence regarding the best approach for these cases, and we think that invasive treatment should be tailored according to the heart’s anatomy and patient risk.
