13. Transradial approach for coronary interventions
OBJECTIVE: To assess the feasibility and safety of coronary interventions performed through the radial artery. METHODS: We studied 103 patients with ages from 38 to 86 years (57±8.7), 90 (87%) males, and: radial pulse with a good amplitude, presence of ulnar pulse, a good collateral flow through the palmar arch assessed with the Allen's test. RESULTS: The v

14. Clinical significance of in-hospital reocclusion after mechanical reperfusion and percutaneous transluminal coronary angioplasty for acute myocardial infarction
OBJECTIVE: To analyze the effects of in-hospital reocclusion of reperfused AMI culprit coronary arteries in mortality and to identify the predictors. METHODS: The present study comprises a sample of 155 patients with AMI who underwent successful mechanical reperfusion by direct coronary angioplasty and angiographic control during hospitalization or before di

15. Effect of percutaneous transluminal coronary angioplasty on arrhythmias complicating angina.
Four patients who had stenosis of a single major coronary artery which was treated by percutaneous transluminal coronary angioplasty are described. Three had exercise induced myocardial ischaemia complicated by ventricular tachycardia, fibrillation, and sinus bradycardia, respectively. Asystole developed in a fourth patient who had spontaneous chest pain. Af

16. Successful repeat percutaneous transluminal coronary angioplasty after failed coronary artery surgery for left main coronary artery dissection.
A 57 year old man required emergency coronary artery bypass surgery after dissection of the left main coronary artery during percutaneous transluminal coronary angioplasty. His symptoms recurred when the vein grafts became occluded. A dilatation device with the lowest profile was used to reduce the need for firm support from the guiding catheter during repea

17. Contraindications for Percutaneous Transluminal Coronary Angioplasty in Treatment of Unstable Angina Pectoris
In recent years, the indications for percutaneous transluminal coronary angioplasty have expanded to include multivessel disease, unstable angina pectoris, stenosis of coronary bypass grafts, and recent total coronary occlusion. To evaluate our experience in using percutaneous transluminal coronary angioplasty to treat unstable angina, we reviewed the record

18. Benign coronary perforation during percutaneous transluminal coronary angioplasty.
In two patients percutaneous transluminal coronary angioplasty was complicated by coronary perforation. In both cases the complication was managed conservatively.

19. Branch retinal artery occlusion secondary to percutaneous transluminal coronary angioplasty.
We report on a patient suffering a branch retinal artery occlusion immediately following percutaneous transluminal coronary angioplasty. Balloon angioplasty may produce ocular embolic events consistent with previously reported neurological complaints.

20. Percutaneous Transluminal Coronary Angioplasty in Multilesion Disease: Complete Versus Incomplete Revascularization
We report the results of percutaneous transluminal coronary angioplasty (PTCA) in the first 200 consecutive patients to undergo this procedure for multilesion coronary disease at Dunedin Hospital.

21. Rotational ablation of discrete lesions in the coronary arteries is safe. A nonrandomized comparison with percutaneous transluminal coronary angioplasty.
Rotational ablation is receiving increasing attention as a new therapeutic intervention for coronary artery disease. In a nonrandomized study, we compared echocardiographic regional wall-motion scores of patients treated with rotational ablation with those of patients treated with percutaneous transluminal coronary angioplasty. We found that rotational ablat

22. Distal Coronary Hemoperfusion and Prolonged Balloon Inflation for Acute Occlusion: Occurring during Percutaneous Transluminal Coronary Angioplasty
We report 3 cases that demonstrate the use of distal coronary hemoperfusion with prolonged balloon inflation to treat acute coronary occlusion occurring during percutaneous transluminal coronary angioplasty. Despite acute occlusion, 2 of the patients had a good angioplasty result, and the 3rd underwent elective coronary bypass surgery. Thus, emergency corona

23. Assessment of left ventricular performance during percutaneous transluminal coronary angioplasty: a study by intravenous digital subtraction ventriculography.
Left ventricular performance during percutaneous transluminal coronary angioplasty was assessed in 52 patients by intravenous digital subtraction ventriculography. After injection of contrast into the right atrium ventriculograms were obtained before and during balloon inflation. In 37 patients they were also obtained after the procedure. A 12 lead electroca

24. High-risk coronary angioplasty assisted by active hemoperfusion. A feasibility study.
We assessed the effectiveness of distal hemoperfusion support during gradual, prolonged balloon inflation during percutaneous transluminal coronary angioplasty in high-risk patients. The patients were identified as having a poor left ventricular ejection fraction ( < 35%), > 50% of viable myocardium at risk percutaneous coronary balloon angioplasty, or both.
