OBJECTIVE: To examine the presence and localization of lipid-core plaque (LCP) in coronary vessels with chronic total occlusions (CTOs) using near-infrared spectroscopy (NIRS). METHODS: NIRS imaging was performed after guidewire crossing of the occlusion in 15 patients with CTOs. LCP was defined as ≥2 adjacent 2 mm yellow blocks on the block chemogram. We also measured the maximum lipid-core burden index (LCBI) in a 4 mm length of artery (maxLCBI4mm). Large LCP was defined as maxLCBI4mm ≥500...

BACKGROUND: This study investigated the morphologic changes in the biceps tendon using ultrasonography before and after successful arthroscopic posterosuperior rotator cuff repair. METHODS: Forty-four patients (44 shoulders) underwent arthroscopic posterosuperior rotator cuff repair with 1-year postoperative magnetic resonance imaging (MRI) follow-up. The patients comprised 22 men and 22 women with an average age of 61 years. The cross-sectional area (CSA) of the biceps tendon in the bicipital groove was measured, and the vascularity in the bicipital groove was graded as 0 to 3, based on the signal density of the anterior circumflex artery, using power Doppler ultrasonography...

We report a rare case of cardiac failure for intrapericardial hematoma 11 years after coronary artery bypass grafting. A 59-year-old man was admitted to our hospital with cardiac tamponade. Echocardiography and computed tomography scan showed severe compression of the left ventricle(LV) by a large mass sized about 5×8 cm. Coronary angiography showed total occlusion at circumflex branch (Cx) #11. The mass was diagnosed with intrapericardial hematoma. We performed removal of hematoma in the pericardial cavity, and removed hematoma had 126 g...

AIMS: We aimed to quantify the relative contributions of the medial femoral circumflex artery (MFCA) and lateral femoral circumflex artery (LFCA) to the arterial supply of the head and neck of the femur. MATERIALS AND METHODS: We acquired ten cadaveric pelvises. In each of these, one hip was randomly assigned as experimental and the other as a matched control. The MFCA and LFCA were cannulated bilaterally. The hips were designated LFCA-experimental or MFCA-experimental and underwent quantitative MRI using a 2 mm slice thickness before and after injection of MRI-contrast diluted 3:1 with saline (15 ml Gd-DTPA) into either the LFCA or MFCA...

BACKGROUND: Heavy coronary artery calcification is responsible for stent underexpansion, which is associated with increased in-stent restenosis. Here we report a case in which optical coherence tomography (OCT) demonstrated that the metal component of an underexpanded stent previously implanted in a heavy calcified lesion had been completely removed after ablation with rotational atherectomy. CASE PRESENTATION: An 83-year-old man with exertional angina was referred to our hospital...

Heart is supplied by right and left coronary arteries. Therefore, the knowledge of normal and variant anatomy of both these arteries and their configurations is indispensable for proper understanding of diagnosis and treatment of dreaded cardiac diseases. During routine cadaveric dissection, a heart of an adult female with anomalous course of Right Coronary Artery (RCA), new variant of trifurcated Left Coronary Artery (LCA) and partial atresia of circumflex (CX) artery was detected. Trifurcation of LCA into anterior interventricular, CX and a ramus intermedius without giving accessory branches has been reported...

A 70-year-old man with hypertension was admitted to our coronary ICU with acute anterior MI. Emergent primary PCI was planned and coronary angiography was performed. LAD artery was totally occluded in the proximal segment just after a huge 32 × 26 mm sized aneurysm. Emergent CABG operation was performed in 75 minutes because of multivessel disease including the RCA and left circumflex artery. Aneurysm was ligated and coronary bypass was performed using LIMA and saphenous grafts. The postoperative course of the patient was uneventful...

AIMS: Alcohol septal ablation (ASA) is an established treatment option in HOCM. ASA is ineffective in some: inaccurate infarct and inability to identify a vessel contribute. We aimed to improve accuracy of infarct using CT angiography guidance and provide a more predictable and satisfactory outcome. METHODS AND RESULTS: Twenty-one successive patients with symptomatic LVOT obstruction refractory to medication underwent CT angiography planning to guide ASA. CT was performed using a dual source CT system...

BACKGROUND: Drug-eluting stent (DES) -induced coronary vasospasm is a well known phenomenon after stent implantation; however, the extent of this risk is still unknown. We report a case in which DES-induced severe coronary vasospasm was clinically suspected as a cause of subacute stent thrombosis (ST). CASE PRESENTATION: A 67-year-old man came to our hospital due to chest pain with mild exercise. He was diagnosed with effort angina by coronary angiography and underwent DES implantation in the mid-left ascending artery (LAD) after the administration of dual anti-platelet therapy...

INTRODUCTION: Floppy glans syndrome (FGS) is a potential complication of penile prosthesis placement in patients with erectile dysfunction. FGS affects a very small proportion of these patients, and it can manifest in a ventral, dorsal, or lateral droop of a hypermobile glans, which can cause affected patients to complain of painful, unsatisfying, or otherwise difficult attempts at sexual intercourse. Incorrect cylinder sizing can even result in extreme conditions such as flail penis or S-shaped deformity...

Bronchial artery embolization is now a common treatment for massive pulmonary hemoptysis if flexible bronchoscopy at the bedside failed to control the bleeding. Complications of this technique range from benign chest pain to devastating neurological impairments. We report the case of a 41-year-old man who developed an ST elevation myocardial infarction during bronchial artery embolization, presumably because of coronary embolism by injected particles. In this patient who had no previously known coronary artery disease, we retrospectively found a communication between the left bronchial artery and the circumflex coronary artery...

The aim was to compare absolute quantified myocardial perfusion (MP) to semi-quantitative measurements of MP using MRI for detection of ischemia. Twenty-nine patients underwent rest and stress MP imaging obtained by 1.5T MRI and analyzed using own developed software and by commercial available software. Linear regression analysis demonstrated that absolute quantitative data correlated stronger to maxSI (rest: r=0.296, p=.193; stress: r=0.583, p=0.011; myocardial perfusion reserve (MPR): r=0.789, p<0.001; and Δ myocardial blood flow (Δ MBF: r=0...
