A 69-year-old man with effort angina was admitted to our institution. Echocardiography showed poor left ventricular systolic function with akinesis of the anterior wall and severe hypokinesis of the inferior wall. We performed coronary angiography, which revealed two diseased vessels including chronic total occlusion in the left anterior descending artery and severe stenosis in the right coronary artery (RCA). In addition, aortography revealed aortoiliac occlusive disease known as Leriche syndrome. As the patient's symptom was stable, we first planned to perform endovascular therapy (EVT) for Leriche syndrome to make a route for intra-aortic balloon pumping. We prepared a bi-directional approach from bi-femoral arteries and a left brachial artery. The guidewire was passed through the occlusive area using the retrograde approach. The self-expanding stents were deployed by a kissing technique. At one week after EVT, a 6Fr sheath was inserted from the right radial artery and an intra-aortic balloon pump was successfully inserted through the right femoral artery for percutaneous coronary intervention (PCI) to the RCA. Two drug-eluting stents were successfully deployed to RCA after using an atherectomy device (rotablator). We reported the case as a successfully performed PCI to the RCA after EVT for Leriche syndrome.

AbstractWe report an extremely rare case of a 14-month-old girl who was diagnosed with a single right coronary artery with coronary artery fistula communicating with the right ventricle and congenital absence of left coronary artery. Angiography showed a dilated and tortuous single right coronary artery draining into the right ventricle, absence of left coronary system, and left ventricular coronary circulation supplied via collateral vessels.

Asymptomatic 17-years-old boy with a suspicion of the heart tumor was admitted to the Cardiology Department for further investigation. Due to the murmur over the heart echocardiography was performed revealing a bright mass near the left ventricular apex. He was in a good physical condition, no symptoms like chest pain, shortness of breath, syncope, palpitations were reported. On physical examination diminished heart sounds and systolic murmur 2-3/6 in the Levin’s scale over the heart were found. Laboratory data including troponin T, CK, CK-MB, NSE, urea acid, marker were within normal limits. On ECG abnormalities of the repolarization were recorded (ST segment depression and T waves inversion in the II, III, aVF leads). Transthoracic echocardiogram revealed a 4.7 x 5.8 cm tumor within the postero-lateral wall of the left ventricle, without left ventricular inflow nor outflow obstruction. Based on cardiac magnetic resonance hemangioma supplied from the right coronary artery was suspected. Cardiac catheterization was performed, the left ventricular mass with supply from vascular network of the right coronary artery was confirmed. No abnormalities of the central nervous system in magnetic resonance were found. Full-body positron emission tomography showed cardiac mass without any evidence of extra-cardiac fluorodeoxyglucose-avid disease. Cardiac hemangioma was recognized. Pharmacological treatment with propranolol was introduced without any impact on the tumor size during 6 months follow-up.
