The transvenous implantation of cardiac devices may sometimes cause serious complications involving the coronary arteries. The left anterior descending artery may be injured during nonapical right ventricular implantation while a right atrial lead may injure the right or circumflex coronary artery. Injury of a left internal mammary graft to a coronary artery may cause myocardial infarction.

A 69 year old male, with a previous percutaneous revascularization of the mid-circumflex with a bare metal stent in 2007 was admitted to our centre for unstable angina. The angiography showed a severely calcified coronary tree with a functionally severe plaque on the proximal left anterior descending artery (LAD) and a critical focal lesion on the proximal right coronary artery. After a high pressure predilation on the proximal LAD, the balloon ruptured causing a retrograde LAD-left main (LM) dissection that was rapidly sealed with three overlapping zotarolimus-eluting stents from medial LAD to LM...

Coronary artery disease (CAD) rates are higher in Asian-Indians than in Caucasians. CAD occurs at an earlier age in this group, with about a quarter of all myocardial infarctions occurring under the age of 40. Previous reports have suggested smaller coronary artery size in Asian-Indians as a major cause for increased CAD in this population. This study sought to evaluate the size of normal "atheroma-free" segments of the epicardial coronary arteries in Asian-Indians and Caucasians aged ≤40 years undergoing coronary artery intervention in other diseased segments...

OBJECTIVE: Although coronary perivascular adipose tissue (PVAT) may play important roles as a source of inflammation, the association of coronary PVAT inflammation and coronary hyperconstricting responses remains to be examined. We addressed this important issue in a porcine model of coronary hyperconstricting responses after drug-eluting stent implantation with (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomographic imaging. APPROACH AND RESULTS: An everolimus-eluting stent (EES) was randomly implanted in pigs into the left anterior descending or the left circumflex coronary artery while nonstented coronary artery was used as a control...

INTRODUCTION: Coronary chronic total occlusions (CTOs) are commonly encountered during diagnostic angiograms. With recent advances, especially in experienced centers, success rates with CTO percutaneous coronary intervention (PCI) have approached 80% or higher. It is important to note that despite these advancements in techniques, CTOs remain difficult to treat. We present a case of a left circumflex artery (LCX) CTO that was successfully revascularized using a microcatheter balloon pinning technique that allowed additional wire support...

Hyun Ho Han, Daiwon Jun, Goo Hyun Mun, Suk-Ho Moon
In spite of thorough presurgical planning, emergency situations requiring longer pedicle length may arise during anterolateral thigh (ALT) free flap surgeries. While performing vessel graft for pedicle lengthening, discrepancy may occur because of a certain genetic predisposition or vascular variation at the anastomosis site of the graft vessel and the flap pedicle. A 76-year-old male patient with neurofibromatosis type I had a 15 x 10 cm defect, which was caused by radical excision of a malignant peripheral nerve sheath tumor on his back...

Coronary artery fistulae are rare cardiac anomalies with a prevalence of 0.2% of all the patients undergoing coronary angiography. The majority of them are congenital and generally origin from the right coronary artery. Occasionally acquired (mostly iatrogenic) fistulae can develop. Although frequently subclinical, symptoms of angina and congestive heart failure may occur. We present an unusual well-illustrated case of a strongly dilated circumflex coronary artery with formation of two giant aneurysms and fistulous communication towards the right atrium...

BACKGROUND: The optimal treatment for concomitant two-vessel coronary artery disease (CAD) and moderate to severe ischemic mitral regurgitation (IMR) remains unclear. We compared the results of a staged percutaneous coronary intervention followed by minimally invasive mitral valve surgery (PCI+MIVS) versus combined coronary artery bypass graft and mitral valve surgery (CABG+MVS) in this population. METHODS: All consecutive patients with two-vessel CAD and moderate to severe IMR, who underwent PCI+MIVS or CABG+MVS at our institution between February 2009 and April 2014, were retrospectively evaluated...
