BACKGROUND Carotid percutaneous transluminal angioplasty may be a useful non-surgical procedure for carotid stenosis, particularly for lesions not suitable for surgery. OBJECTIVES The objective of this review was to assess the effect of carotid percutaneous transluminal angioplasty compared with carotid endarterectomy (in patients suitable for surgery) or medical therapy (in patients not suit...

Percutaneous transluminal coronary angioplasty with metal stent placement has become a well-developed treatment modality for coronary stenotic lesions. Although infection involving implanted stents is rare, it can, however, occur with high morbidity and mortality. We describe herein a case of an inserted coronary stent that was infected and complicated with recurrent stent thrombosis, pseudoane...

PERCUTANEOUS transluminal angioplasty of peripheral, renal, and visceral arteries has been in widespread clinical use for more than a decade, and it is estimated that approximately 100,000 of these procedures are performed annually in the United States. In recent years controversy has developed among the various medical disciplines about who is qualified to perform percutaneous transluminal ang...

Introduction: In former studies on ischaemic preconditioning, adenosine was found to trigger this cardioprotective process. After promising experiments in rabbit hearts and the first clinical use during emergency percutaneous transluminal coronary angioplasty in patients, we started to investigate the ability of adenosine to protect the myocardium during standard cross-clamping bypass surgery. ...

OBJECTIVES We assessed the feasibility and reproducibility of the instantaneous diastolic coronary flow velocity-pressure gradient relation to characterize different degrees of coronary stenoses. BACKGROUND Assessment of the hemodynamic significance of coronary stenoses can be difficult. Using sensor-tipped guidewires, various physiologic indexes can be determined in the catheterization labor...
