Coronary artery aneurysm is an uncommon disease. When it is associated with significantly obstructive coronary artery disease, percutaneous transluminal coronary angioplasty with graft-coated stent implantation usually provides favorable results. Non-coated stents may have the potential risk of thromboembolism. We present a patient with unstable angina who received elective balloon angioplasty ...

Objective: To compare the costs of coronary bypass surgery (CBS) and percutaneous transluminal coronary angioplasty (PTA) over a one-year follow up. Method: Eight-six patients were submitted to 87 CBS and 240 patients to 267 PTA, between October 2003 and April 2004. The mean age of the two groups was 62 years. The CBS group was submitted to a mean of 3.7 bypasses/patient, using 96.5% of arteria...

BACKGROUND Although paclitaxel-coated balloon (PCB) angioplasty is an effective procedure for in-stent restenosis (ISR) after coronary stenting, recurrent ISR after PCB angioplasty still occurs. The aim of this study was to evaluate the predictors of recurrent ISR after PCB angioplasty for ISR.Methods and Results:A total of 157 ISR lesions treated with PCB angioplasty from January 2014 to May 2...

Coronary dissection has a significant morbidity and mortality. The ideal management of acute coronary occlusion is the prompt restoration of the vessel patency to limit the extent and duration of ischemia. In the setting of dissection during percutaneous procedure, the usual approach has been emergency aortocoronary bypass surgery. The authors present a case of a patient with left main dissecti...

In 1974, at the Medical Policlinic of the University of Zürich, German-born physician-scientist Andreas Grüntzig (1939-1985) for the first time applied a balloon-tipped catheter to re-open a severely stenosed femoral artery, a procedure, which he initially called "percutaneous transluminal dilatation". Balloon angioplasty as a therapy of atherosclerotic vascular disease, for which Grüntzig and ...

Over the last two decades, a better understanding of the blood coagulation and platelet function, the introduction of effective pharmacological agents, increased use of coronary angiography, the development of advanced percutaneous techniques such as, percutaneous transluminal coronary angioplasty (PTCA), and coronary stenting have made a dramatic change in the acute management of myocardial in...

OBJECTIVES To investigate the relation between diastolic aortic pressure response and left ventricular systolic dysfunction during percutaneous transluminal coronary angioplasty. BACKGROUND The abnormal diastolic blood pressure rise during exercise in patients with coronary artery disease probably reflects left ventricular systolic dysfunction rather than the number of stenosed coronary arter...

L eft main (LM) coronary artery stenoses have conventionally been precluded from percutaneous coronary angioplasty because of the prohibitive risk of irreversible hemodynamic collapse after acute closure of the artery, and a relatively high risk of late sudden death. l When protected by left anterior descending and circumflex coronary artery bypass grafts, angioplasty of the LM coronary artery ...

CASE REPORT T his 48-year.old man was in good health until April 1988, when he noted the onset of exertional chest pain. One month later, he underwent cardiac catheterization, which revealed a totally occluded left circumflex coronary artery. His only risk factor for atherosclerotic cardiovascular disease was cigarette use. He underwent successful percutaneous transluminal coronary angioplasty ...
