Thrombus exerts a major impact on the performance and outcome of primary and rescue interventions in acute ST-elevation myocardial infarction. Although the optimal treatment of thrombotic lesions is still controversial, thrombus aspiration provides an effective method to achieve successful reperfusion during primary angioplasty. We compared clinical and angiographic outcomes in 286 patients wit...

OBJECTIVE To evaluate the safety and efficacy of a prototype temporary stent (RX Flow Support Catheter, Advanced Cardiovascular Systems) in maintaining coronary perfusion and improving vessel patency in the event of acutely compromised flow complicating percutaneous transluminal coronary angioplasty. DESIGN Prospective clinical study as part of a multicentre trial. SETTING Regional cardiac ...

OBJECTIVE To investigate changes in cytokine expression in the coronary circulation induced by percutaneous transluminal coronary angioplasty (PTCA). METHODS The study involved 32 patients with ischaemic heart disease who underwent elective PTCA for isolated stenotic lesions of the left coronary artery. Ten patients had plain old balloon angioplasty, 10 had percutaneous transluminal rotationa...

Of 552 patients undergoing percutaneous transluminal coronary angioplasty 102 had coronary artery spasm superimposed on atherosclerotic narrowing. Coronary angioplasty was successful in 97 (95%). The patients were discharged on a regimen of nifedipine (40-60 mg/day). Seventy six patients were symptom free 6-8 months after the procedure. Restenosis was detected in 35% of patients. Coronary arter...

Multivascular preventive and therapeutic approaches are necessary in patients with coronary artery disease because atherosclerosis has a common systemic pathogenesis. We present a rare case of sudden cardiac arrest with acute myocardial infarction induced by the total occlusion of left subclavian artery (LSCA) in a patient with a history of previous coronary artery bypass surgery using the left...

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. ...

In our first 169 consecutive patients admitted to undergo percutaneous transluminal coronary angioplasty (PTCA) serial bicycle ergometric exercise sessions were scheduled to assess long-term-exercise performance. In 160 of these 169 patients (95%) an average of seven ergometric measurements were available during a mean follow-up period of 29 months (range 1 to 60 months). Two groups were formed...

W hen Odysseus attempted to sail unharmed between Scylla and Charybdis, he could not have dreamt to ever be quoted in relation to restenosis after percutaneous transluminal coronary angioplasty (PTCA). To be truly successful, balloon dilatation should change the preexistent stenotic lesion to the extent that sufficient luminal widening is achieved and restenosis does not occur. Nevertheless, ap...
