Patients with 12q14 microdeletion can present with short stature with or without relative macrocephaly. When associated with relative macrocephaly, the phenotype resembles Silver-Russell syndrome (SRS). Short stature is attributable to haploinsufficiency of HMGA2, but a patient with a deletion at the HMGA2 locus only did not have macrocephaly. Hence, the(More)
Periprocedural myocardial infarction (PMI) is one of the major complications of percutaneous coronary intervention (PCI). We investigated the influence of coronary plaque burden and characteristics on PMI using intravascular ultrasound (IVUS) with radiofrequency-based tissue characterization technology (iMAP). The study population consisted of 33(More)
Patients with acute coronary syndrome (ACS) are thought to have multiple vulnerable coronary plaques. We analyzed non-culprit plaques in patients with ACS vs. stable angina pectoris (SAP) by means of color-coded intravascular ultrasound (iMap-IVUS). Patients who underwent percutaneous coronary intervention were divided into an ACS group (n = 39) and an SAP(More)
Saphenous vein graft aneurysm (SVGA) is one of the chronic complications after coronary aorta bypass grafting (CABG) and may be caused by atherosclerosis-like phenomena of the vein graft, weakness around the vein valve, rupturing of the suture of the graft anastomosis, or perioperative graft injury. We describe a case of a large, growing saphenous vein(More)
AIM Epicardial adipose tissue (EAT) is implicated in the development of coronary atherosclerosis.We sought to investigate the association between the EAT thickness and presence of multivessel disease (MV) in patients with acute myocardial infarction (AMI). METHODS We enrolled 45 consecutive patients with AMI who underwent primary percutaneous coronary(More)
A 56-year-old man with a history of old myocardial infarction and coronary artery bypass grafting was performed percutaneous coronary intervention to the totally occluded lesion of native left anterior descending artery. He developed a coronary arterial perforation that led to a large dissecting sub-epicardial hematoma. Emergent surgery was performed, and a(More)
OBJECTIVE Although the plaque characteristics have been recognized in patients with acute myocardial infarction (AMI), the plaque spatial distribution is not well clarified. Using color-mapping intravascular ultrasound (iMAP-IVUS), we examined culprit lesions to clarify plaque morphology, composition and spatial distribution of the sites of potential(More)
