[Intracoronary administration of antithrombotic agents via a perfusion balloon catheter in patients with ST-segment elevation myocardial infarction presenting with massive intraluminal thrombus and failed aspiration]. / Apport de l'administration intracoronaire d'antithrombotiques par cathéter à ballon de perfusion en phase aiguë d'infarctus du myocarde avec thrombus massif et échec de la thromboaspiration.

BACKGROUND: Massive intracoronary thrombus is associated with adverse procedural results including failed aspiration and unfavourable reperfusion. We aim to evaluate the effect of the intracoronary administration of antithrombotic agents via a perfusion catheter in patients with ST-segment elevation myocardial infarction (STEMI) presenting with a large thrombus burden and failed aspiration. METHODS: We retrospectively analyzed the thrombus burden, the TIMI grade flow, and the myocardial Blush in 25 consecutive STEMI patients with a large thrombus burden and failed manual aspiration, who received intracoronary infusion of glycoprotein IIb/IIIa inhibitors (N=17) or bivalirudine (N=8) via a 6F-infusion catheter (ClearWay™ RX) RESULTS: Mean age was 67±14 years, 16 patients (64 %) presented with anterior STEMI, and 7 (28 %) with cardiogenic shock. Immediately after intracoronary infusion, the TIMI flow grade improved of 2 grades in 7 patients (28 %), and 1 grade in 14 (56 %), a complete resolution of the thrombus was observed in 9 patients, and a >50 % resolution in 12. Blush was improved of 3 grades in 15 patients (60 %), of 2 grades in 7 (28 %), and Blush grade 0 remained in 3. At the end of procedure, we observed normal TIMI 3flow in most patients (92 %), a complete resolution of thrombus in 80 %, and a Blush grade 3 in 68 %. CONCLUSIONS: In STEMI patients presenting with a large thrombus burden and failed aspiration, intracoronary administration of glycoprotein IIb/IIIa inhibitors or bivalirudin via the perfusion catheter ClearWay™ RX significantly reduced the thrombus burden and improved the TIMI flow and the Blush grade, without bleeding.

SIMMEON-Prep study: SIMulation of Medication Errors in ONcology: prevention of antineoplastic preparation errors.

WHAT IS KNOWN AND OBJECTIVE: Medication errors (ME) in oncology are known to cause serious iatrogenic complications. However, MEs still occur at each step in the anticancer chemotherapy process, particularly when injections are prepared in the hospital pharmacy. This study assessed whether a ME simulation program would help prevent ME-associated iatrogenic complications. METHODS: The 5-month prospective study, consisting of three phases, was undertaken in the centralized pharmaceutical unit of a university hospital of Lyon, France. During the first simulation phase, 25 instruction sheets each containing one simulated error were inserted among various instruction sheets issued to blinded technicians. The second phase consisted of activity aimed at raising pharmacy technicians' awareness of risk of medication errors associated with antineoplastic drugs. The third phase consisted of re-enacting the error simulation process 3 months after the awareness campaign. The rate and severity of undetected medication errors were measured during the two simulation (first and third) phases. The potential seriousness of the ME was assessed using the NCC MERP(®) index. RESULTS AND DISCUSSION: The rate of undetected medication errors decreased from 12 in the first simulation phase (48%) to five in the second simulation phase (20%, P = 0.04). The number of potential deaths due to administration of a faulty preparation decreased from three to zero. Awareness of iatrogenic risk through error simulation allowed pharmacy technicians to improve their ability to identify errors. WHAT IS NEW AND CONCLUSION: This study is the first demonstration of the successful application of a simulation-based learning tool for reducing errors in the preparation of injectable anticancer drugs. Such a program should form part of the continuous quality improvement of risk management strategies for cancer patients.

[Transradial approach for diagnostic angiography]. / Artériographie diagnostique par voie transradiale.

Seventy five arteriographies were performed via the transradial route using 5F 130cm - long catheter. Prior to puncture the radial artery was evaluated with Allen test. Satisfying quality examinations were obtained for the thoracic aorta, selective carotid arteries examinations, infra renal aorta, pelvic and legs arteries. The major advantages obtained for the technique were the very low rate complication and technical failure. Transradial route for arteriography is a reasonable alternative approach to transfemoral or brachial arteriography for out patient management (peripheral angiography) in case in which transfemoral route is not feasible but also with patients with important haemorragic-risks.

[Coronary angioplasty in the acute phase of myocardial infarction in a low-volume center]. / Angioplastie coronaire à la phase aiguë de l'infarctus du myocarde dans un centre de faible volume.

The efficacy of coronary angioplasty in the treatment of acute myocardial infarction was assessed in a low volume centre. Between January 1994 and May 1999, 148 consecutive patients (mean age 59 years, 81% men) with acute myocardial infarction, admitted within 12 hours, were included in this retrospective analysis. On admission, 14% of patients were in cardiogenic shock. The average time between the onset of chest pain and arrival at hospital was 244 +/- 183 mins. Reperfusion (TIMI 3 flow) was obtained on average 111 +/- 60 mins after arrival at hospital and 81 mins after informing the on-call team. After angioplasty, residual stenosis < 50% was obtained in 91% of cases. TIMI 3 flow was obtained in 85% of cases (TIMI 2 + 3 in 93% of cases). Over the years, the delay before treatment decreased and the results of angioplasty improved. In the last 79 patients, residual stenosis < 50% was obtained in 95% of cases, TIMI 3 flow in 87% of cases (TIMI 2 + 3 in 97% of cases). The stenting rate increased from 16% before 1997 to 61% thereafter. The hospital mortality was 4%. Direct or salvage angioplasty in the first 12 hours of myocardial infarction in some low volume centres may be carried out safely with intervention times and success rates comparable to those reported in the literature.

Elevated cardiac troponin I predicts a high-risk angiographic anatomy of the culprit lesion in unstable angina.

BACKGROUND: This study assessed the relation between the angiographic appearance of the culprit lesion and cardiac troponin I (cTnI) or C-reactive protein (CRP) elevations within the first 24 hours in unstable angina. Intracoronary thrombus or a complex morphology, is frequently observed on angiography in patients with unstable angina and is associated with a higher rate of spontaneous or coronary angioplasty-related complications. Biochemical parameters related to myocardial injury (eg, cTnI) or to systemic inflammation (eg, CRP) are known prognostic markers for clinical outcome and may help in angiographic risk stratification to provide new adjunctive therapy. METHODS AND RESULTS: We studied 100 patients admitted for unstable angina with angiographically proven coronary artery disease (with normal creatine kinase [CK] and CK-MB mass). Serum concentrations of cTnI (N < 0.4 ng/mL) and CRP (N < 3 mg/L) were measured at admission and 12 and 24 hours later. Multivariate analysis showed that elevated cTnI (>/=0.4 ng/mL) within 24 hours (35 patients) was an independent predictor of an angiographic appearance of the culprit lesion carrying a high risk of major cardiac events in the outcome and whether angioplasty is attempted (coronary thrombus, occlusion, or type C lesions; odds ratio 4.1, 1. 6 to 10.5). cTnI levels at admission and CRP at 0, 12, and 24 hours were not predictive of high-risk angiographic anatomy. CONCLUSIONS: In patients with unstable angina and angiographically proven coronary artery disease, increased cTnI within 24 hours of admission but not increased CRP is associated with an angiographic appearance of the culprit lesion carrying a high risk of complication, especially in the event of angioplasty.
