Recently, coronary artery disease such as angina pectoris and myocardial infarction has become the major causes of death. As a method of medical treatment for the disease, the pharmacological approaches and the surgical operations are executed. Especially, percutaneous coronary intervention (PCI) using catheters are the mostly preferred treatment for coronary artery diseases. The PCI technologi...

A 41-year-old woman who had been fitted with a pacemaker 18 years prior presented for lead extraction because of device infection. First, we tried laser sheath. However, it cannot cross the binding in the innominate vein. Then we switched to the rotating mechanical sheath. Although it crunched through binding tissue, the progress halted. We removed the sheath and found pieces of calcified tissu...

CEPHALEXIN, a new semi-synthetic antibiotic derived from cephalosporin C, has the same basic nucleus and the same range of activity as its predecessors, cephalothin and cephaloridine but has the advantage that it can be given orally. As this drug is relatively new, few side-effects have been described. The following case report is of a boy, aged 14 years, who developed acute intravascular haemo...

background  recent investigations show that both proliferation and secretion of macromolecules by cells can be regulated by low level laser therapy (lllt). the aim of this study was to determine whether lllt could induce a bio-stimulatory effects on human gingival fibroblasts (hgf3-pi 53). therefore, the effect of laser irradiation on human gingival cell proliferation and collagen type i gene e...

Complex coronary artery disease with severe calcification can be challenging to treat, a higher risk of procedural complications and major adverse cardiac events. Intravascular lithotripsy (IVL) is pioneering technology for the treatment critically calcified coronaries. IVL utilizing localized pulsatile sonic pressure waves at low provides novel approach lesion preparation severely plaques. The...

OBJECTIVES The purpose of this study was to evaluate the frequency, amount and distribution of target lesion calcification in patients undergoing transcatheter therapy for symptomatic coronary artery disease. BACKGROUND Coronary artery target lesion calcification may be an important determinant of response to transcatheter therapy: balloon angioplasty causes dissections in calcified lesions, ...
