[Linking Interventional Cardiology clinical registry data with French hospital administrative data: Development and validation of deterministic record linkage]. / Appariement entre un registre régional de pratiques en cardiologie interventionnelle et la base médico-administrative d'hospitalisation française : développement et validation d'un algorithme d'appariement déterministe.

BACKGROUND: To recreate the in-hospital healthcare pathway for patients treated with coronary angiography or percutaneous coronary intervention, we linked the interventional cardiology registry (ACIRA) and the pseudonymized French hospital medical information system database (PMSI) in the Aquitaine region. The objective of this study was to develop and validate a deterministic merging algorithm between these exhaustive and complementary databases. METHODS: After a pre-treatment phase of the databases to standardize the 11 identified linking variables, a deterministic linking algorithm was developed on ACIRA hospital stays between December 2011 and December 2014 in nine interventional cardiology centers as well as the data from the consolidated PMSI databases of the Aquitaine region from 2011 to 2014. Merging was carried out through 12 successive steps, the first consisting in strict linking of the 11 variables. The performance of the algorithm was analyzed in terms of sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). Strategies complementary to the initial algorithm (change in the order of variables and base preprocessing) were tested. Comparative analysis of merged/unmerged patients explored potential causes of mismatch. RESULTS: The algorithm found 97.2% of the 31,621 ACIRA stays to have sensitivity of 99.9% (95% CI [99.9; 99.9]), specificity of 97.9% (95% CI [97.7; 98.1]), PPV of 99.9% (95% CI [99.9; 99.9]) and NPV of 96.9% (95% CI [96.7; 97.1]). Complementary strategies did not yield better results. The unmerged patients were older, and hospitalized mostly in 2012 in two interventional cardiology centers. CONCLUSION: This study underscored the feasibility and validity of an indirect deterministic pairing to routinely link a registry of practices using hospital data to pseudonymized medico-administrative databases. This method, which can be extrapolated to other health events leading to hospitalization, renders it possible to effectively reconstruct patients' hospital healthcare pathway.

Electromagnetic analysis for optical coherence tomography based through silicon vias metrology.

This paper reports on progress in the analysis of time-domain optical coherence tomography (OCT) applied to the dimensional metrology of through-silicon vias (TSVs), which are vertical interconnect accesses in silicon, enabling three-dimensional (3D) integration in microelectronics, and estimates the deviations from earlier, simpler models. The considered TSV structures are 1D trenches and circular holes etched into silicon with a large aspect ratio. As a prerequisite for a realistic modeling, we work with spectra obtained from reference interferograms measured at a planar substrate, which fully includes the dispersion of the OCT apparatus. Applying a rigorous modal approach, we estimate the differences to a pure ray tracing technique. Accelerating our computations, we focus on the relevant fundamental modes and apply a Fabry-Perot model as an efficient approximation. Exploiting our results, we construct and present an iterative procedure based on the minimization of a merit function, which concludes TSV heights reliably, accurately, and rapidly from measured interferograms.

[Unprotected left main coronary artery stenting: immediate and medium-term outcomes of 24 procedures]. / Angioplastie du tronc gauche non protégé: évolutions immédiates et à moyen terme de 24 procédures.

OBJECTIVES: We have examined the immediate and long-term patient outcomes following angioplasty of unprotected left main coronary artery stenoses. BACKGROUND: Coronary disease of the unprotected left main artery is considered as an absolute contraindication for percutaneous intervention. Recently, several studies have reported good results with unprotected left main coronary artery stenting when surgical revascularization was contraindicated. METHODS: From October 2004 to June 2006, 24 patients with a contraindication to surgery and with unprotected left main coronary artery stenoses received stents. Patients were surveyed at one, six and 12 months with telephone interviews. RESULTS: The procedure's success rate was 100%. The percentage of stenosis and minimum lumen diameter (MLD) were respectively 63.4% (+/-15.4) and 1.1mm (+/-0.5) before procedure; 13.8% (+/-10.2) and 3.2mm (+/-0.5) after angioplasty. The size of stents averaged 3.79 mm (+/-0.46) with an average 1.04 stents per patient. During follow up, two deaths occurred (8.3%). No intrastent restenosis was found. CONCLUSIONS: Stenting of unprotected left main coronary artery stenoses may be a safe and effective alternative to coronary artery bypass especially when surgical revascularization is contraindicated. However, further studies with larger patient populations are needed to assess the late outcome and to clarify the relevance of percutaneous intervention compared to surgery.

[Multiple myocardial infarctions: pancoronary destabilization evaluated by cardiac MRI]. / Infarctus du myocarde à localisations multiples: preuve par IRM cardiaque des conséquences de la pancoronarite.

PURPOSE: Complete intravascular ultrasound study examination of all three coronary arteries in patients with first acute coronary syndrome very frequently revealed one or more atherosclerotic plaque ruptures associated with the culprit lesion. The aim of this study was to evaluate using cardiac MRI the incidence of multiple necroses in patients with myocardial infarction. The study sought to detect delayed enhancement in a zone different from the necrosis area concerned by the culprit occlusion. METHODS: Eighty consecutive patients who were referred for a first myocardial infarction underwent angioplasty within the first 12 hours after chest pain beginning. Each patient was examined within four to eight days following the acute phase. Cardiac MRI evaluated left-ventricle function (TrueFISP sequence) and used a T2 weighted short-inversion-time, inversion recovery sequence (STIR) in order to visualize myocardial oedema; delayed enhancement imaging data were then acquired after injection of gadolinium. RESULTS: In eight patients (10%), we observed two delayed enhancement areas associated with wall-motion abnormalities. One was attributed to the culprit occlusion; the second corresponded to a different coronary artery. In five patients, this second zone was related to an old coronary occlusion confirmed by angiography and the STIR sequence. However, in three patients, the second delayed enhancement area corresponded to a coronary artery stenosis with normal flow. CONCLUSION: In patient with acute myocardial infarction, MRI sometimes detects a necrosis area which was not initially suspected. This observation illustrates the consequences of pancoronary destabilization.

[Direct thrombin inhibitors in coronary angioplasty. Value of bivalirudin ]. / Inhibiteurs directs de la thrombine dans l''angioplastie coronaire. Place de la bivalirudine.

During coronary angioplasty, the association of platelet inhibitors and antithrombin agents is required to prevent myocardial infarction. Bivalirudine, a synthetic direct thrombin inhibitor, has been widely validated in this context and has shown its efficacy and safety in several comparative studies. It is officially recommended as a replacement of NFH and LMWH associated or not with anti-GPIIb/IIIa agents because at comparable efficacy it causes fewer bleeding complications. In acute coronary syndromes without ST elevation, anti GPIIb/IIIa agents reduce angioplasty-related complications and mortality, especially in high risk patients in salvage situations. In the REPLACE-2 trial the clinical efficacy of bivalirudine (associated only when necessary with anti-GPIIb/IIIa agents) was no less than that of NFH associated systematically with anti-GPIIb/IIIa agents at the time of intervention. The incidents of serious adverse events at 30 days (death, infarctus, emergency revascularisation, major bleeding) in the bivalirudine group was 9.2% versus 10.2% in the NFH group. In a retrospective analysis, these results did not seem to be influenced by the prior administration of clopidogrel. Finally, the one year follow-up results showed a lower mortality in patients treated with bivalirudine (1.9% versus 2.5%), essentially in the high risk sub-groups such as the elderly, the diabetic or the renal failure patients. Clinical trials are underway (ACUITY) to study the interaction of anti GPIIb/IIIa agents with bivalirudine in the first hours of acute coronary syndromes and should confirm a major role of direct anti-thrombin drugs in the safety of angioplasty.

Stent placement compared with balloon angioplasty for small coronary arteries: in-hospital and 6-month clinical and angiographic results.

BACKGROUND: Stenting has been demonstrated to be superior to balloon angioplasty in de novo focal lesions located in large native vessels. However, in small vessels, the benefit of stenting remains questionable. METHODS AND RESULTS: A total of 381 symptomatic patients with de novo focal lesion located on a small coronary segment vessel (<3 mm) were randomly assigned to either stent implantation (192 patients; 197 lesions) or standard balloon angioplasty (189 patients; 198 lesions). The primary end point was the angiographic restenosis rate at 6 months, as determined by quantitative coronary angiography. On intention-to-treat analysis, angiographic success rate and major adverse cardiac events were comparable: 97.9% and 4.6% versus 93.9% and 5.8% in the stent group and the balloon group, respectively. After the procedure, a larger acute gain was achieved with stent placement (1.35+/-0.45 versus 0.94+/-0.47 mm, P=0.0001), resulting in a larger minimal lumen diameter (2.06+/-0.42 versus 1.70+/-0.46 mm, P=0.0001). At follow-up (obtained in 91% of patients), angiographic restenosis rate was 21% in the stent group versus 47% in the balloon group (P=0.0001), a risk reduction of 55%. Repeat target lesion revascularization was less frequent in the stent group (13% versus 25%, P=0.0006). CONCLUSIONS: Elective stent placement in small coronary arteries with focal de novo lesions is safe and associated with a marked reduction in restenosis rate and subsequent target lesion revascularization rate at 6 months.

Carvedilol for prevention of restenosis after directional coronary atherectomy : final results of the European carvedilol atherectomy restenosis (EUROCARE) trial.

BACKGROUND: In addition to its known properties as a competitive, nonselective beta and alpha-1 receptor blocker, carvedilol directly inhibits vascular myocyte migration and proliferation and exerts antioxidant effects that are considerably greater than those of vitamin E or probucol. This provides the basis for an evaluation of carvedilol for the prevention of coronary restenosis. METHODS AND RESULTS: In a prospective, double-blind, randomized, placebo-controlled trial, 25 mg of carvedilol was given twice daily, starting 24 hours before scheduled directional coronary atherectomy and continuing for 5 months after a successful procedure. The primary end point was the minimal luminal diameter as determined during follow-up angiography 26+/-2 weeks after the procedure. Of 406 randomized patients, 377 underwent attempted atherectomy, and in 324 (88.9%), a

A comparison of systematic stenting and conventional balloon angioplasty during primary percutaneous transluminal coronary angioplasty for acute myocardial infarction. STENTIM-2 Investigators.

OBJECTIVES: In a multicenter, randomized trial, systematic stenting using the Wiktor stent was compared to conventional balloon angioplasty with provisional stenting for the treatment of acute myocardial infarction (AMI). BACKGROUND: Primary angioplasty in AMI is limited by in-hospital recurrent ischemia and a high restenosis rate. METHODS: A total of 211 patients with AMI <12 h from symptom onset, with an occluded native coronary artery, were randomly assigned to systematic stenting (n = 101) or balloon angioplasty (n = 110). The primary end point was the binary six-month restenosis rate determined by core laboratory quantitative angiographic analysis. RESULTS: Angiographic success (Thrombolysis in Myocardial Infarction [TIMI] flow grade 3 and residual diameter stenosis <50%) was achieved in 86% of the patients in the stent group and in 82.7% of those in the balloon angioplasty group (p = 0.5). Compared with the 3% cross-over in the stent group, cross-over to stenting was required in 36.4% of patients in the balloon angioplasty group (p = 0.0001). Six-month binary restenosis (> or = 50% residual stenosis) rates were 25.3% in the stent group and 39.6% in the balloon angioplasty group (p = 0.04). At six months, the event-free survival rates were 81.2% in the stent group and 72.7% in the balloon angioplasty group (p = 0.14), and the repeat revascularization rates were 16.8% and 26.4%, respectively (p = 0.1). At one year, the event-free survival rates were 80.2% in the stent group and 71.8% in the balloon angioplasty group (p = 0.16), and the repeat revascularization rates were 17.8% and 28.2%, respectively (p = 0.1). CONCLUSIONS: In the setting of primary angioplasty for AMI, as compared with a strategy of conventional balloon angioplasty, systematic stenting using the Wiktor stent results in lower rates of angiographic restenosis.

The French Randomized Optimal Stenting Trial: a prospective evaluation of provisional stenting guided by coronary velocity reserve and quantitative coronary angiography. F.R.O.S.T. Study Group.

OBJECTIVES: We sought to make a prospective comparison of systematic stenting with provisional stenting guided by Doppler measurements of coronary velocity reserve and quantitative coronary angiography. BACKGROUND: Despite the increasing use of stents during percutaneous transluminal coronary angioplasty, it is unclear whether systematic stenting is superior to a strategy of provisional stenting in which stents are placed only in patients with unsatisfactory results or as a bail-out procedure. METHODS: Two hundred fifty-one patients undergoing elective coronary angioplasty were randomly assigned either to provisional stenting (group 1, in which stenting was performed if postangioplasty coronary velocity reserve was <2.2 and/or residual stenosis > or =35% or as bail-out) or to systematic stenting (group 2). The primary end point was the six-month angiographic minimal lumen diameter (MLD). Major adverse cardiac events were secondary end points (death, acute myocardial infarction and target lesion revascularization). RESULTS: Stenting was performed in 48.4% of patients in group 1 and 100% of patients in group 2 (p<0.01). Six months after angioplasty, the MLD did not differ between groups (1.90+/-0.79 mm vs. 1.99+/-0.70 mm, p = 0.39), as was the rate of binary restenosis (27.1% vs. 21.4%, p = 0.37). Among patients with restenosis, 13/32 (40.6%) in group 1 but 100% (25/25) in group 2 had in-stent restenosis (p<0.01). Target lesion revascularization (15.1% vs. 14.4% in groups 1 and 2 respectively, p = 0.89) and major adverse cardiac events (15.1% vs. 16.0%, p = 0.85) were not significantly different. CONCLUSIONS: Systematic stenting does not provide superior angiographic results at six months as compared with provisional stenting.

Primary osteoarthritis of hip, knee, and hand in relation to occupational exposure.

AIM: To identify occupations with excess prevalence of osteoarthritis of the knee, hip, and hand in a nationwide survey and to compare occupations with and without excess prevalence with regard to biomechanical stresses and severity of osteoarthritis. METHODS: Patients presenting with osteoarthritis of the knee, hip, or hand were recruited throughout France by their treating physician who collected information on history, including age at onset, occupation, and occupational stresses to joints. Severity was assessed using joint specific functional status questionnaires: Lequesne for the hip and knee and Dreiser for the hand. The distribution of osteoarthritis patients by occupation was compared with the distribution of occupations in all workers in France to obtain prevalence rate ratios. RESULTS: Occupations with the greatest prevalence rate ratio were female cleaners (6.2; 95% CI 4.6 to 8.0), women in the clothing industry (5.0; 95% CI 3.9 to 6.3), male masons and other construction workers (2.9; 95% CI 2.6 to 3.3), and agriculture male and female workers (2.8; 95% CI 2.5 to 3.2). A twofold greater prevalence rate was observed within certain occupations between self-employed and salaried workers. Early onset of osteoarthritis was seen in the more heavy labour jobs with almost 40% of patients reporting their first symptoms before the age of 50. CONCLUSION: The early onset and severity of osteoarthritis in certain occupations warrants an urgent need for occupation specific studies for the development and evaluation of preventive strategies in this leading cause of disability in Western countries.

[Isotretinoin: compliance with recommendations in childbearing women]. / Isotrétinoïne: suivi de l'application des recommandations des prescriptions chez les femmes en âge de procréer.

INTRODUCTION: The aim of this survey is to ascertain if the incidence of isotretinoin exposed pregnancies was reduced by the late recommendations of prescription and issue (AMM modification on 06/08/2001 and 25/09/2001). METHODS: All isotretinoin exposed pregnancies registered by the French Regional Drug Monitoring Centres, the Information Centre for Teratogenic Agents and Roche (Roaccutane), Pierre Fabre (Curacné Gé) and Expanscience (Procuta Gé) laboratories, from January 1st, 1999 to December 31st, 2002, were analysed. Enforcement of the strengthening of isotretinoin prescription recommendations was analysed on a sample of 68 prescriptions from 45 pharmacies throughout France. RESULTS: In 4 years, 103 isotretinoin exposed pregnancies (Roaccutane 97 p. 100, Curacné(R) Gé 3 p. 100) during teratogenic risk period, were registered. Pregnancy started less than one month after isotretinoin stopping (37 p. 100), during the treatment (43 p. 100), or was in progress when the treatment was initiated (20 p. 100). The reason of the 22 lacking contraception was known 12 times, i.e. an absence of prescription (6 times), a refusal to take a prescribed contraception (3 times) and a self-medication (3 times). Among the 71 pregnancies whose contraceptive status is known, 48 p. 100 could had been avoided if recommendations had been followed (pregnancies due to a premature stopping or an absence of contraception). The issue of pregnancies is a voluntary termination in 60 cases (87 p. 100). Malformations frequency is 25 p. 100. Incidence of isotretinoin exposed pregnancies remained stable, 0.26/1000 treated women (vs 0.34 after 2001's AMM modifications). Of 68 prescriptions studied, 23 (24 p. 100) carried all the legal warnings, which is close to the previous survey's results. Contraception was in accordance with the recommendations in 78 p. 100 of cases and women learned and applied information given in 38 p. 100 of cases. At last, only 6 patients (9 p. 100) have both a correctly written prescription, a contraception and a time between the pregnancy test date and prescription and issue dates, in accordance with the licence and have had a correct information and understood it. Regarding the previous survey, pregnancy test before treatment was more often prescribed (96 p. 100 vs 88 p. 100). On the other hand, less women knew the necessity to keep on taking contraception one month after isotretinoin stopping (82 p. 100 vs 93 p. 100). CONCLUSION: Despite 3 successive isotretinoin prescription and issue recommendations strengthening in childbearing women, pregnancies can't be totally avoided. Bad compliance concerns the prescription and/or an incomplete or not understood information by the patient who does not scrupulously apply the care and contraception agreement. However, this study does not allow to assess the proportion of issued prescriptions despite their non-accordance with the licence criteria. The National Commission of Pharmacovigilance did not like to limit isotretinoin prescription to dermatologists only. It estimates that the administrative authority must intensify information by dermatologists, general practitioners and pharmacists, about measures to take to avoid an exposure to isotretinoin during pregnancy.

[Characteristics and management of ST-elevation myocardial infarction in France: Regional variations in 2010]. / Prise en charge du syndrome coronaire aigu avec sus-décalage de ST en France : variations régionales en 2010.

Data on regional variations in the characteristics, management and early outcome of patients admitted with ST-elevation myocardial infarction (STEMI) in France are limited. We used data from the FAST-MI 2010 registry to determine whether regional specificities existed, dividing the French territory into 6 larger geographical regions. Variations in the patients' characteristics were found, partly related to regional variations in demography. Acute reperfusion strategy showed more use of primary percutaneous coronary intervention in the greater Paris area, compared to other regions, which would be expected owing to geography and local availability of catheterization laboratories. Overall, however, in-hospital management showed more similarities than differences across regions. Complications, and in particular in-hospital mortality, did not differ significantly among regions.

Impact of restenosis after optimal directional coronary atherectomy on regional left ventricular function.

To assess the effect of optimal directional coronary atherectomy (DCA) on restenosis and left ventricular (LV) function, 95 patients who underwent DCA and adjunctive balloon angioplasty for de novo lesions were prospectively followed for 6 months. Absolute and relative coronary lumen measurements were analyzed with online quantitative coronary angiography. LV volumes, ejection fraction, and segmental wall motion were measured off-line according to the radial method for LV cineangiograms acquired in a right anterior oblique projection. Target vessels were the left anterior descending artery in 63 patients and right coronary artery in 32. Mean (+/- SD) reference diameter was 3.58 +/- 0.65 mm. Mean lumen diameter improved significantly after DCA from 1.19 +/- 0.44 to 3.03 +/- 0.45 mm, yielding a 14 +/- 10% residual stenosis. Overall angiographic restenosis rate (> 50% stenosis in diameter) at control was 23%. In patients without restenosis, there were no significant changes in LV volumes or in LV pressures. In this subgroup, ejection fraction improved significantly in the left anterior descending group (mean difference 3 +/- 10%, p < 0.04). Moreover, there was an increase in fractional shortening of all anterior segments (mean difference 11 +/- 16%, p < 0.005). Improvement in fractional shortening was less marked in the right coronary artery group even without restenosis. We conclude that: (1) optimal DCA can achieve a low restenosis rate in selected large vessels, (2) long-term beneficial effects on regional LV function are possible, particularly in patients with left anterior descending disease and in the absence of coronary restenosis.

Early hemodynamic results of left ventricular reconstructive surgery for anterior wall left ventricular aneurysm.

To assess the efficacy of left ventricular (LV) reconstruction after aneurysmectomy, 35 consecutive patients with anterior LV aneurysm were studied before and after surgery. Surgical technique was performed by applying a circular patch after aneurysmectomy to maintain a "more physiological" LV cavity. Myocardial revascularization was performed in all but 1 patient concurrently. Global perioperative mortality was 4.8%. LV filling pressure and volumes and regional wall motion were assessed before and after surgery. The major indication for surgery was angina; 8 patients were in New York Heart Association class III/IV. The results showed a significant decrease in end-diastolic volume index (from 120 +/- 55 ml/m2 to 76 +/- 22 ml/m2, p less than 0.001), end-systolic volume index (from 74 +/- 44 ml/m2 to 40 +/- 18 ml/m2, p less than 0.001) and end-diastolic pressure (from 17 +/- 7 mm Hg to 13 +/- 5 mm Hg, p less than 0.05). Ejection fraction significantly increased (from 39 +/- 13% to 49 +/- 15%, p less than 0.001). LV wall motion significantly improved in all but the anterobasal region; the extent of LV asynergy significantly decreased after surgery. Six of the 35 patients had a deterioration of postintervention ejection fraction (from 44 +/- 14% to 34 +/- 9%). They had no reduction in LV volumes and no improvement in wall kinetics. It is concluded that LV reconstruction after aneurysmectomy induces significant early improvement of global and regional LV function in most patients; postoperative functional improvement is mainly related to the increase in inferior LV wall motion.

Skeletonized right gastroepiploic artery used for coronary artery bypass grafting.

The right gastroepiploic artery has been definitively recognized as a reliable conduit for coronary artery bypass grafting with excellent clinical results and midterm patency. Our experience with internal thoracic artery skeletonization and the similarities between the gastroepiploic and internal thoracic arteries prompted us to modify the gastroepiploic artery harvesting technique. The purpose of this report is to present the advantages of the skeletonized gastroepiploic artery graft.

The pattern of glomerular disease in New Caledonia: preliminary findings.

Two hundred and two renal biopsies from 181 patients in New Caledonia were classified into either primary glomerulonephritis or glomerulopathy associated with systemic disease. These were then compared with 670 similar biopsies from 634 in-patients at Sydney's Royal Prince Alfred Hospital (RPAH). The most prevalent primary glomerular disease among the New Caledonian cases was focal segmental glomerulosclerosis, compared with IgA disease among the RPAH cases. Mesangiocapillary glomerulonephritis, post-infectious glomerulonephritis and minimal lesion nephropathy were all relatively commoner among the New Caledonian biopsies, but the numbers were small. The most prevalent systemic glomerulopathy in the New Caledonian cases were amyloidosis. This was the least common among our RPAH group. Diabetes mellitus and lupus nephritis were also slightly more common in the New Caledonian group. Focal necrotizing/crescentic glomerulonephritis was unusual in the New Caledonian samples, while it was the most common systemic glomerulopathy among the RPAH group.

Primary osteoarthritis and occupations: a national cross sectional survey of 10 412 symptomatic patients.

AIMS: To describe the age standardised prevalence of symptomatic osteoarthritis (OA) in a nationwide cross sectional survey of 10 412 patients in France, and their functional and work limitations. METHODS: Cases in the survey were compared with their expected counterpart by age, gender, and occupational groupings using data from the 1998 French National Survey on Health Impairment and Disability. RESULTS: Women represented 66.2% of the sample; mean age was 66.2 years. One third of patients had OA of the knee, 16% of the hip, and 12% of the hand; a third had multiple joint OA. Peak prevalence of symptomatic OA was in the 60-69 year category in women and in the 70-79 year category in men. Agricultural workers showed a significant excess prevalence of OA, with an observed to expected (O/E) ratio of 1.7 in women and 2.3 in men. Linear trends in prevalences between white collar, "mixed" collar, and blue collar workers were also significant, with odds ratios respectively of 1.0, 2.9, and 2.6 in women and 1.0, 1.2, and 1.7 in men. Specific excess prevalence was found in women among housekeepers (O/E 4.4), and in men among unskilled labour workers (O/E 10.3) and truck drivers (O/E 6.7). Total work disability was highest among blue collar workers and partial disability among agricultural workers. CONCLUSION: Results contribute to the mounting evidence that OA is potentially aetiologically linked to occupation in a sizeable segment of the population and that OA can no longer be considered an inevitable disease of ageing.

Surgery for post infarction ventricular septal defect (VSD): risk factors for hospital death and long term results.

OBJECTIVE: Repair of post infarction ventricular septal defect (VSD) is still a challenging procedure with a high risk of recurrence of the VSD and subsequent mortality. The aim of this retrospective study was to assess if technical change in the surgical procedure was followed by an improvement in recurrence of the VSD and operative results. METHOD: This retrospective study from 1971 to 2001 included 85 patients operated on early (<15 days) after the occurrence of a post infarction VSD. Double patch technique was introduced in 1986. A total of 44 variables were studied by a uni- and multivariate analysis. RESULTS: Hospital death occurred in 36 patients. Significant factors for hospital mortality included: preoperative and evolution of the clinical status, right ventricular function and type of repair (one or two patches). Moreover, no recurrence was observed in patients repaired with the double patch technique (P=0.09). None of the studied variables were significant for long term survival. Concomitant CABG was not associated with higher hospital mortality and long-term survival rate was similar in patients with or without concomitant CABG. CONCLUSION: The use of the double patch technique and glue by avoiding recurrence of the VSD played a role in the reduction of the hospital mortality. This technique has to be recommended in the early repair of post infarction VSD. Concomitant CABG can be done safely to control the added risk of an associated coronary artery lesion.

Clinical study of an LH-RH agonist (ICI 118.630, Zoladex) in the treatment of prostatic cancer.

Eighty patients with prostatic cancer have been treated with an LH-RH analogue (Zoladex). Ten had no metastasis, and hormone therapy was used as an induction treatment before curative radiotherapy. The others had metastatic disease and, in some cases, had already received some form of endocrine therapy. Patients received a monthly injection of Zoladex (3.6 mg). No progressive disease was noted among patients with nonmetastatic tumors; of the patients with metastases, those who were previously untreated had a higher response rate (14.8% complete response) and longer progression-free and overall survival. Toxicity was mild in spite of two cases of disease flare.

Mycotic aneurysm of the celiac trunk: radical resection and reconstruction without prosthetic material.

The Authors report a case of mycotic aneurysm of the celiac trunk, originating from bacterial endocarditis on the mitral valve. The technique was excision and revascularization without interposition of any material: for the moment it is the first time that a mycotic aneurysm of the celiac trunk is treated in this manner. The post-operative course was normal.
