A 61-year-old male had a successful left total knee arthroplasty but one year later developed a deep diphtheroides infection of the joint following femoral percutaneous transluminal coronary angioplasty without antimicrobial prophylaxis. Diphtheroides is an uncommon organism to infect a joint replacement and it has not been reported in the medical literature previously to our knowledge. There i...

Coronary artery disease in patients with end-stage renal disease occurs several dozen times more often than in the general population. Atherosclerotic changes in coronary arteries in dialysed patients are more diffused and calcified, which hampers the percutaneous coronary angioplasty. We present a case of an 84-year-old dialysed patient, in whom complex percutaneous coronary intervention of th...

Despite the increasing use of percutaneous transluminal coronary angioplasty and intracoronary stent placement for the treatment of obstructive coronary artery disease, a large subset of coronary lesions cannot be adequately treated with balloon angioplasty and/or intracoronary stenting alone. Such lesions are often heavily calcified or fibrotic and undilatable with the present balloon technolo...

A 48-year-old male patient diagnosed with Kawasaki disease in childhood presented with recurrent angina after undergoing coronary artery bypass surgery in 1996. Percutaneous transluminal coronary angioplasty and intracoronary stent placement to a lesion in the proximal ramus intermedius were performed successfully. This case illustrates the complementary nature of percutaneous and surgical myoc...

In a prospective evaluation of the safety of short-term observation after elective percutaneous transluminal coronary angioplasty (PTCA) in 1,900 consecutive patients, 1 of 1,680 patients triaged to discharge after 4 hours of observation reached the primary end point of acute recurrent ischemia, 7 patients underwent repeat PTCA during 4 hours of observation, and 66 of 187 patients selected for ...

The use of percutaneous coronary intervention (PCI) to treat ischemic coronary artery disease (CAD) has expanded dramatically over the past three decades. Coronary balloon angioplasty, or percutaneous transluminal coronary angioplasty (PTCA), was first performed by Andreas Gruentzig in 1977 using a fixed-wire balloon catheter. The procedure was initially limited to the fewer than 10% of patient...

of the angioplasty segment between the concentric and eccentric lesion subgroups was not significant (analysis of variance) at any time after PTCA. The degree of vasoconstriction observed in the angioplasty segment of both the concentric and eccentric lesion subgroups were significantly greater than that of the control segment at 15 and 30 minutes after PTCA (p CO.01 and <0.005, respectively). ...

OBJECTIVES This study aimed to investigate the roles of intracoronary derived coronary flow velocity reserve (CFVR) and myocardial perfusion scintigraphy (single photon emission computed tomography, or SPECT) for management of an intermediate lesion in patients with multivessel coronary artery disease. BACKGROUND Evaluation of the functional significance of intermediate coronary narrowings (4...

introduction: ischemic preconditioning mediated by potassium channels is a physiological protective mechanism, . it is hypothesized that nicorandil, which is a potassium channel activator, could protect the heart via preconditioning. materials and methods:this clinical trial was conducted on 162 patients undergoing percutaneous coronary intervention (pci) in quem hospital, from jan2013 to jan 2...
