Abstract
Aim: To demonstrate that in patients with acute coronary syndrome (ACS), using Cordis 6F Infiniti diagnostic catheters for angioplasty may represent a safe alternative associated with lower contrast volume and radiation dosage, improving cardiovascular and renal outcomes.
Material and Methods: In 1,800 patients with ACS (2,331 lesions/2,603 stents), angioplasty was performed with Cordis 6F Infiniti Thrulumen diagnostic catheters. Primary angioplasty was performed in 545 cases, and only balloon angioplasty in 67 patients. All procedures were performed through the femoral route, and switch-over to the radial route was made in 5 cases due to associated aortic/iliac obstructive lesions. Iodixanol was used in 76% of cases, and tirofiban in 99% of cases with adjusted dosages based on creatinine values. The mean contrast volume used per patient was 28 mL (± 6 mL) including the angiogram prior to the angioplasty.
Results: The median fluoroscopy time was 4.4 min (IQR 3–6.8), the mean fluoroscopy time was 5.59 min (± 0.28), the median dose-area product or kerma-area product was 1,507 µGym2 (IQR 918–2,611), median total or cumulative dose including backscatter was 2,702 µGym2 (IQR 1,805–4,217), and the median cumulative skin dose was 468 mGy (IQR 296–722). Groin hematoma was seen in 7 cases, proximal mild edge dissection in the deployed stent in 3 cases, and acute in-hospital stent thrombosis in 7 cases. In total, 33 deaths were registered and 19 of these patients had cardiogenic shock, of which 11 subjects were late presenters. Three patients died after discharge due to possible acute stent thrombosis.
Conclusions: Angioplasty and stenting can be performed safely in patients with acute coronary syndromes using Cordis 6F diagnostic catheters. The procedure was associated with a very low volume of contrast and radiation dose, leading to improved clinical outcomes..

Abstract
Coronary artery spasm is a known complication of coronary interventions, for which intracoronary nitroglycerin (ICN) is the treatment of choice. Some forms of intense spasm are resistant to ICN. Calcium channel antagonists are also known to be effective for coronary artery spasm, including nitroglycerin-resistant spasm. Here we describe a protocol for the clinical use of intracoronary diltiazem (ICD). By this protocol, ICD can be safely given without disturbing the clinical status of patients. ICD (2.5 mg) given slowly over 1 minute produced no vasodilitation of normal vessel segments but did produce significant dilatation of stenotic segments above and beyond the effects of nitrates. Mean minimum lumen diameter increased 18%, from 0.89 +/- 0.06 mm to 1.06 +/- 0.07 mm (mean +/- SEM, P < 0.001). ICD produced clinically insignificant changes in systolic blood pressure, diastolic blood pressure, heart rate, and PR, QRS, and QT intervals. This protocol has been employed to safely use ICD to relieve both nitroglycerin-resistant epicardial artery spasm and nitroglycerin-resistant distal microvascular spasm (the no-reflow phenomenon).

Abstract
Distal microvascular spasm is a somewhat uncommon occurrence following PTCA and often does not respond well to nitroglycerin. We report several patients who developed distal microvascular spasm that was refractory to intracoronary nitroglycerin but responded promptly to intracoronary verapamil.

Abstract
Coronary artery spasm unresponsive to intracoronary nitroglycerin was observed in eight patients undergoing percutaneous transluminal coronary angioplasty for unstable ischemic symptoms (unstable angina or recent nontransmural infarction, or both). All patients manifested eccentric lesions angiographically with the right coronary artery involved in four, circumflex artery in two and left anterior descending in two. Severe coronary spasm was documented angiographically in all patients after angioplasty and resulted in symptomatic and electrocardiographic evidence of ischemia. Multiple sites of spasm were present in the dilated vessel in three patients. Coronary artery spasm persisted despite the infusion of large doses of intracoronary nitroglycerin (200 to 2,000 micrograms, mean 850 micrograms) over 10 min. Administration of intracoronary verapamil (1 to 1.5 mg over 10 min) resulted in complete relief of spasm with restoration of brisk anterograde flow in all patients. These findings suggest that intracoronary verapamil may be a useful agent for the relief of coronary spasm occurring in the setting of coronary angioplasty.

Abstract
We studied the incidence of spontaneous and ergonovine-induced coronary arterial spasm during repeat coronary angiography in 96 consecutive patients with single-vessel disease who had undergone successful angioplasty. Follow-up angiography was performed after a mean of 6 months (1-8 months). Sixty patients demonstrated no restenosis and in 36 patients restenosis (greater than 50% restenosis) occurred. Spasms of the arteries at the site of dilatation were significantly (P less than 0.001) more frequent in patients with restenosis (18/36; 50%) than in patients without restenosis (4/60; 7%). Before angioplasty, no differences were found in the clinical characteristics between the two groups. Likewise, the morphologic results of angioplasty were identical. Despite long-term treatment with nifedipine (30-60 mg daily) and aspirin (0.5 g daily), 14 of 18 patients with restenosis and coronary spasm suffered from spontaneous angina, as compared to only 3 of 18 patients with restenosis without demonstrable spasm. Three of the 4 patients without restenosis but with detectable spasm were also symptomatic. Thus our findings suggest that spasm of the coronary arteries achieves some importance as a pathophysiological factor for recurrence following coronary angioplasty.

Abstract
Nineteen (86%) of 22 patients with variant angina and important coronary stenoses (greater than 60%) had successful percutaneous transluminal coronary angioplasty. The acute complications in two patients were not caused by coronary spasms but by dissection with disturbance of perfusion. One of these two patients required a coronary bypass graft; the other was treated conservatively. Myocardial infarction developed in both patients. Despite long term administration of nifedipine (30-80 mg daily), restenoses occurred within six months (on average after 10 weeks) in nine patients with symptoms and one without. In four patients the restenoses exceeded the degree of stenosis before angioplasty. Five patients were revascularised by surgical means. Vessels in three out of four patients were later successfully dilated. After a mean period of observation of 24 months (6-51 months) 18 of the 19 patients are symptom free and do not require medication. The results confirm that angioplasty is an effective method of treating patients with variant angina and important coronary stenoses. The problem of the high frequency of restenosis, however, remains unresolved.

Abstract
In order to ascertain whether coronary angiography performed immediately after the completion of successful percutaneous transluminal coronary angioplasty (PTCA) can be used as an index of the final outcome of the procedure, angiography was repeated thirty minutes post PTCA in twenty consecutive patients undergoing elective PTCA. Comparison of the pre PTCA, immediate post PTCA and thirty minutes post PTCA angiograms showed that the initial angiographic success of 77.8% improvement in lumen diameter from pre PTCA to immediate post PTCA was reduced by 16.2% to 61.6% thirty minutes later. We conclude that angiographic changes continue to occur in the immediate post PTCA period and that the immediate post PTCA angiogram may not represent the true outcome of the procedure.

Abstract
Percutaneous transluminal coronary angioplasty (PTCA) was performed with initial success in 7 patients with variant angina and significant (greater than 60%) coronary stenosis. The mean degree of stenosis was reduced from 77 +/- 12% to 29 +/- 15% and the mean systolic pressure gradient from 78 +/- 18 to 25 +/- 9 mmHg. Apart from a reversible spasm in one patient, PTCA was free of acute complications. Despite long-term treatment with nifedipine, nitrates, and warfarin (patients 1 to 5) or aspirin (patients 6 and 7) restenoses occurred in 4 of 7 patients. An aortocoronary bypass was necessary in 2 patients, 3 respectively 6 weeks after PTCA because of tighter restenoses than before PTCA. Another patient underwent successful repeat angioplasty after 6 weeks and remained improved. During a mean follow-up observation of 21 months (6 to 30 months), 4 patients were asymptomatic, even without medication. In one of these patients, the follow-up angiography (6 months after PTCA) demonstrated a restenosis. These results suggest that PTCA demonstrated a restenosis. These results suggest that PTCA can be performed without a higher risk of acute complications in patients with variant angina. Although the recurrence rate is high in these patients, sustained clinical improvement was achieved in a substantial percentage of patients in our study.

Abstract
The effects of relative contraindications on the immediate results of PTCA were investigated in 1,939 patients, and on long-term results in 998 patients with isolated stenosis of 1 coronary artery. Immediate results subjected to analysis were: success rate, major complications (coronary occlusion, MI and death) and emergency CABG. The analysis of long-term results included: status of angina pectoris, occurrence of MI, restenosis, repeat PTCA, CABG and death. Unstable angina and previous MI had no negative effects on immediate results, whereas a significantly lower success rate was noted in patients with angina for more than 1 year compared to patients with angina of shorter duration (p less than 0.05) and patients older than 60 years compared with younger patients (p less than 0.01). During follow-up, patients with unstable angina had higher CABG rate (p less than 0.01); the other relative clinical contraindications to PTCA did not exert adverse effects. Angiographically, there was a lower immediate success rate in patients with nonproximal stenosis (p less than 0.001) and in patients with calcium in the affected artery (p less than 0.01) and at the site of stenosis (p less than 0.001). Patients with tubular or diffuse stenoses had similar success rates but higher rates of complications, excluding death, than those with discrete stenoses (p less than 0.01). Patients with eccentric stenoses had a lower success rate and a higher rate of complications and emergency CABG than patients with concentric stenoses (p less than 0.001 for all 3 variables).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A patient with reversible coronary artery spasm superimposed on fixed atherosclerotic coronary disease was treated with percutaneous transluminal angioplasty. The procedure successfully dilated the atherosclerotic lesion. However, 20 minutes later, the patient developed coronary artery spasm at the angioplasty site. Sublingual nitroglycerin, sublingual nifedipine, intravenous nitroglycerin, and repeated boluses of intracoronary nitroglycerin alleviated episodes of spasm, but failed to prevent recurrence. The patient was successfully treated with a continuous intracoronary infusion of nitroglycerin. Patients with coronary artery spasm in addition to fixed obstructive coronary disease may be at higher risk for spasm after percutaneous transluminal angioplasty. Continuous intracoronary infusion of nitroglycerin may be an effective therapy for recurrent coronary artery spasm occurring in the catheterization laboratory.
