[Recommendations for training in cross-sectional cardiac imaging]. / Recommandations pour la formation en imagerie en coupes du coeur et des vaisseaux.

The recent and future advancements that are known in the field of cardiac imaging imply an optimal training of the operators. This training concerns medical specialists whether originating from radiology or cardiology. The training of the medical specialists in cardiac imaging entitles 3 main essential steps: The basic training taking place within each specialty, allowing the fellow to get acquainted with the clinical and technical basics. The specialized training, delivered principally in post-residency. This training must include an upgrading of each specialty in the domain that does not concern it (a technical base for the cardiologist, a physio-pathological and clinical base for the radiologist). It must include a specific theoretical training covering all aspects of cardiac imaging as well as practical training in a certified training centre. The continuous medical training and maintenance of skills that allow a sustained activity in the field and the obligation to regularly participate in the actions of specific validated training. The different aspects of these rules are exposed in this chapter.

[Resistant hypertension by unadvertised non-compliance detected by psychiatric expertise and drug dosages]. / Hypertension artérielle résistante par inobservance non avouée dépistée par expertise psychiatrique et dosages médicamenteux.

The management of patients with resistant hypertension remains a major challenge in daily clinical practice in order to limit macro and microvascular impact. However, lack of compliance often remains one of the main etiologies of resistant hypertension. Through a clinical case of complex therapeutic non-compliance, we will detail the frequency, the screening and the management of therapeutic non-compliance. Finally, we will specify the contribution of drug dosages and psychological expertise in screening non-observant patients with presumed resistant hypertension.

Position paper of French Interventional Group (GACI) for TAVI in France in 2018.

Aortic stenosis is a frequent disease in the elderly. Its prevalence is 0.4% with a sharp increase after the age of 65, and its outcome is very poor when the patient becomes symptomatic. The interventional procedure known as TAVI (trans-catheter aortic valve implantation), which was developed in France and carried out for the first time in Rouen by Prof. Alain Cribier and his team in 2002, has proven to be a valid alternative to surgical aortic valve replacement. At first, this technique was shown to be efficient in patients with contra-indications to surgical treatment or deemed to be at high surgical risk. Given the very promising outcomes achieved as a result of close heart team collaboration, appropriate patient selection, simplified procedures and reduced complication rates, transfemoral (TF) TAVI is now preferred in symptomatic intermediate risk patients>75 years old according to the latest ESC guidelines. In 2017, in France, TAVI is currently performed in 50 centers with on-site cardiac surgery. The 2016 TAVI outcomes recorded in the French national TAVI registry (France TAVI) are very encouraging and show that for 7133 patients treated (age 83.4±7 years, logistic Euroscore 14%), 87% of whom via the TF approach, cross-over to surgery was very low (0.5%) with a 3.0% in-hospital mortality rate. The substantial increase in TAVI indications and the improvement of its outcomes may in the near future call for a reconsideration of the number of high volume centers authorized to carry out this technique.

[The best of interventional cardiology in 2006]. / L'essentiel de l'année 2006 en cardiologie interventionnelle.

The year 2006 was a landmark in interventional cardiology. Confirmations of results of large-scale trials and meta analyses, the commercialisation of new drug-elution stents, discussions about well established methods, questions about long-term outcomes of dilated patients, have made 2006 a particularly rich year in controversy, especially during its last three months.

[Tolerance and efficacy of early nicotine substitution after acute coronary syndromes]. / Tolérance et efficacité de la substitution nicotinique précoce au décours d'un syndrome coronaire aigu.

The object of this study was to assess the cardiovascular tolerance and efficacy of early nicotine substitution therapy in 100 patients admitted to the Coronary Care Unit for acute coronary syndromes (ACS). The files of the first 100 consecutive patients having received nicotine substitution therapy immediately after an ACS were consulted retrospectively and a questionnaire was sent to all patients. A reply was obtained in 90% of cases. In this series, there was a 7% rate of cardiovascular events in the days following hospital discharge, comparable to previously reported results. The smoking relapse rate at six months after the ACS was 38.9%, a percentage which was less than in previously reported series. Although consultations to help stop smoking and nicotine substitution did not seem to have significant benefits in this study, the authors recommend continuing and improving the management of coronary patients who smoke.

[Acute pericarditis: results of a survey of treatment practices of cardiologists]. / Péricardite aiguë.

UNLABELLED: Benign acute pericarditis is a common disorder. Although, at first glance, its management appears well defined, the guidelines issued by professional societies with respect to optimal treatment and length of its administration remain vague. METHODS: a brief, anonymous questionnaire probing into treatment practices was sent in April 2005 to all cardiologists of Brittany. RESULTS: we collected 164 analyzable questionnaires out of 248 submitted (66%). The initial investigations in presence of acute pericarditis included an electrocardiogram in 100% of cases, an echocardiogram in 95%, and screening biochemistry in 93% of cases. Systematic hospitalisation was advised by only 24% of cardiologists. Aspirin was prescribed as first choice treatment in 92.5% of cases. Duration of treatment recommendations varied widely, from <5 days by 2.5%, between 5 and 10 days by 25.5%, 11 and 15 days by 23.0%, 16 to 21 days by 35.3%, and for >21 days by 14% of cardiologists. Hospital-based cardiologists were more likely to systematically hospitalise their patients than outpatient practice-based physicians (79.5% versus 5.1%; p<0.001) as well as to order an initial biochemical screening tests (100% versus 81.4%, p<0.01). Cardiologists <42 years of age recommended significantly fewer hospitalisations than older physicians (6.8% versus 36.4%: p<0.001). CONCLUSIONS: the management of acute, benign pericarditis was limited nearly exclusively to the prescription of aspirin. Duration of treatment varied widely. These observations are concordant with data published in the literature (where the recommended duration of treatment is systematically missing).

[The best of interventional cardiology in 2005]. / L'essentiel de l'année 2005 en cardiologie interventionnelle.

During 2005, the evolution of interventional cardiology has largely been dominated by the trial of active endoprostheses, whose advantage has been consistently shown by various studies, mete-analyses and surveys. Extending their use to new indications and evaluating new drugs have also been studied. In parallel, clinical trials have been performed in the promising field of percutaneous treatment of valvular heart disease, particularly mitral insufficiency and calcified aortic stenosis in the adult.

Women in interventional cardiology: The French experience.

OBJECTIVES: Exploring the discrepancy in sex-ratio among interventional cardiologists by analysing the population of the female interventionalist. BACKGROUND: Despite an increase number of women who graduate from medical school in France during the last generation today, women represent only 24% of all cardiologists and 3% are interventional cardiologists. To face this international gender-based issue of interventional cardiology, committees were established in US (WIN) and recently within the EAPCI: the Women EAPCI chaired by Drs Mehilli and Mauri. In France, the Intervention'Elles committee emerged in order to participate in this concern. METHODS: As a first initiative, the Intervention'Elles group launched an e-survey to obtain information on the population of French female interventional cardiologists, focused on demography, work patterns, maternity and radiation exposure. RESULTS: Mean age is 40 years old (±7,4), 68% are working in large volume center, 28% have also structural interventional activity. Only 40% have left arm coverage. Despite 80% of French female interventional cardiologists wear personal dosimeters only 45% of them have a dosimetry feedback. Interestingly, even if 54% of women have children (mean: 1.9±1) 28% of them report that childbearing had interfered with their career plan. CONCLUSION: This questionnaire identifies for the first time the women population in interventional cardiology in France and highlights some of the issues encountered in more detail. This first descriptive step would help to develop strategies for attaining gender equality in interventional cardiology.

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.

Long-term left ventricular pacing: assessment and comparison with biventricular pacing in patients with severe congestive heart failure.

OBJECTIVE: The purpose of this study is to report prospectively the results of six-month follow-up of permanent left ventricular (LV) based pacing in patients with severe congestive heart failure (CHF) and left bundle branch block (LBBB). BACKGROUND: Left ventricular pacing alone has been demonstrated to result in identical improvement compared to biventricular pacing (BiV) during acute hemodynamic evaluation in patients with advanced CHF and LBBB. However, to our knowledge, the clinical outcome during permanent LV pacing alone versus BiV pacing mode has not been evaluated. METHODS: Pacing configuration (LV or BiV) was selected according to the physician's preference. Patient evaluation was performed at baseline and at six months. RESULTS: Thirty-three patients with advanced CHF and LBBB were included. Baseline characteristics of LV (18 patients) and BiV (15 patients) pacing groups were similar. During the six-month follow-up period, seven patients died three BiV and four LV). In the surviving patients at 6 months, 8 of 14 patients in the LV group and 9 of 12 in the BiV group were in New York Heart Association class I or II (p = 0.39). No significant difference was observed between the two groups in terms of objective parameters except for LV end-diastolic diameter decrease (-4.4 mm in BiV group vs. -0.7 mm in LV group; p = 0.04). CONCLUSION: At six-month follow-up, a trend toward improvement was observed in objective parameters in patients with severe CHF and LBBB following LV-based pacing. The two pacing modes (LV and BiV) were associated with almost equivalent improvement of subjective and objective parameters.

[Interventricular management of patients over the age of 75 with acute coronary syndromes without persistent ST elevation]. / Stratégie interventionnelle de prise en charge des patients âgés de plus de 75 ans hospitalises pour syndrome coronaire aigu sans sus-décalage persistant du segment ST: resultats d'un registre prospectif multicentrique regional.

The aim ot tnis study was to assess the results of interventional strategy in patients over 75 years of age admitted to hospital with acute coronary syndromes (ACS) without persistent ST elevation. Over three months, patients over the age of 75 undergoing coronary angiography for ACS were included in a multicentre register and followed up for 6 months. A total of 126 patients with an average age of 79 were included: 70% had at least one poor prognostic factor. The treatment on admission included: Aspirin (84%), Clopidogrel (60%), anti GpIIb-IIIa (12%) and Heparin (81%, of which 3/4 of cases were low molecular weight heparins). Coronary angiography (average delay 80 hours) showed single, double and triple vessel disease in 21, 29 and 35% of cases respectively. Coronary angioplasty was proposed in 83 patients and carried out in 82. Eleven patients underwent coronary artery bypass grafting and 31 were treated medically. During the hospital phase, there were 3 major cardiovascular complications: 1 death during coronary angiography, 1 intra-stent thrombosis and 1 death in the group undergoing bypass grafting, with no major bleeding complications. At 6 months, there were 8 (6.5%) major cardiovascular adverse events with 6 in the "angioplasty" group; 5 deaths (3 cardiac deaths), 3 myocardial infarcts. Two thirds of patients were asymptomatic. The authors conclude that interventional strategy in ACS of elderly patients is associated with a low rate of major adverse events. The benefits of this strategy should be confirmed by randomised trial.

[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.

Evaluation of left ventricular based pacing in patients with congestive heart failure and atrial fibrillation.

Acute hemodynamic data of left ventricular based pacing were assessed in 2 groups of patients with severe cardiac failure: 11 patients with atrial fibrillation and 17 patients with sinus rhythm. Both biventricular and left ventricular pacing significantly improved acute hemodynamic findings to a similar degree in both groups, suggesting that left ventricular based pacing may be beneficial in patients with severe cardiac failure regardless of whether or not they are in sinus rhythm.

Clinical and angiographic results of stenting for long coronary arterial atherosclerotic lesions.

A prospective registry of 187 patients who underwent percutaneous coronary angioplasty with attempted long NIR stent delivery was performed. A successful stent delivery was achieved in 93% of cases with a low rate of major cardiovascular events, and 6-month follow-up showed low rates of clinical events, new revascularization procedures, and angiographic restenosis.

Left ventricular-based pacing in patients with chronic heart failure: comparison of acute hemodynamic benefits according to underlying heart disease.

BACKGROUND: Acute left ventricular-based pacing has been shown to improve hemodynamics in patients with severe heart failure and left bundle branch block (LBBB). However, it is not known whether the cause of the underlying heart disease influences the potential effect of left ventricular-based pacing. OBJECTIVES: The aim of this study was to determine whether beneficial hemodynamic effects of acute left ventricular-based pacing in severe chronic heart failure are dependent on underlying heart disease. METHODS: After coronary angiography, patients with severe heart failure and LBBB were separated into two groups: dilated (25 patients; 20 male) and ischemic cardiomyopathy (21 patients; 20 male). Hemodynamic parameters were evaluated at baseline and during left ventricular-based pacing. RESULTS: Improvement in hemodynamic parameters were similar in both groups, during acute left ventricular pacing (changes expressed in percentage): pulmonary capillary wedge pressure, -16+/-15% vs. -14+/-10%; V wave amplitude, -25+/-18% vs. -21+/-17%; and biventricular pacing, -15+/-15% vs. -11+/-11% and -23+/-18% vs. -16+/-18%, respectively. CONCLUSION: Underlying heart disease does not influence the response to acute left ventricular-based pacing in patients with severe heart failure and LBBB. This finding provides support for including all patients with enlarged heart and heart failure in future studies evaluating left ventricular-based pacing.

Evaluation of left ventricular function and mitral regurgitation during left ventricular-based pacing in patients with heart failure.

BACKGROUND: Beneficial effects of left ventricular (LV)-based pacing on acute hemodynamic parameters were reported in several series, but only a few studies examined the long-term effects of this new pacing procedure. AIMS: To assess long-term effects of permanent LV-based pacing on LV function and mitral regurgitation (MR) in patients with refractory congestive heart failure (CHF). METHODS: A prospective evaluation of LV function and MR was performed in 23 patients with severe but stable CHF and left bundle branch block (mean QRS: 186+/-31 ms) by radionuclide and echocardiographic techniques at baseline and 6 months after implantation of a permanent LV-based (LV alone: 13 patients; biventricular: 10 patients) pacemaker programmed either in a DDD mode (sinus rhythm; n=14) or in a VVIR mode (atrial fibrillation; n=9). RESULTS: Compared to baseline, the 6 months follow-up visit demonstrated a significant increase in radionuclide derived LV ejection fraction from 23.3+/-7 to 26.2+/-7% (P<0.01) and in echocardiographic LV fractional shortening from 13+/-4 to 16+/-6% (P<0.05), without any change in cardiac index, a significant decrease in LV end-diastolic diameter (from 73.2+/-6 to 71.2+/-7 mm; P<0.05), end-systolic diameter (from 63.6+/-6 to 60.2+/-8 mm; P<0.05) and color Doppler MR jet area (from 11.5+/-6 to 6.6+/-4 cm(1); P<0.001). A comparison of patients with LV pacing alone and patients with biventricular pacing showed similar beneficial effects of pacing on MR severity in the two subgroups and a non-significant trend for a better improvement of LV function during biventricular pacing. CONCLUSION: Thus, in patients with severe CHF and left bundle branch block, permanent LV-based pacing may significantly improve LV systolic function and decrease MR.

Coronary artery reconstruction for extensive coronary disease: 108 patients and two year follow-up.

BACKGROUND: Surgical coronary artery reconstruction for diffuse coronary disease is described and assessed. METHODS: A long arteriotomy, internal thoracic artery graft, and exclusion of atheromatous plaques from the coronary lumen are the bases of the technique. One hundred eighteen reconstructions were performed in 108 patients with a mean age of 59 years. Stable angina was present in 62% of patients and unstable angina in 22%. Sixteen percent had had a recent myocardial infarction. The reconstructions involved 94 left anterior descending coronary arteries, 17 marginal, 5 diagonal, and 2 right coronary arteries. RESULTS: The perioperative mortality rate was 3.7% (4 patients). The rate of perioperative myocardial infarction was 6.3%. Mean follow-up was 29 months (standard deviation, 10 months). Two patients were lost to follow-up. Ninety patients were free from angina and cardiac-related events. Five patients sustained a myocardial infarction, 3 were in congestive heart failure, 3 had class II angina, and 1 died of stroke. Seventy-four of the surgical coronary artery reconstructions have been angiographically evaluated (29 months): 94.6% of the internal thoracic artery grafts were completely patent, and 70 of the reconstructions were patent without restenosis. String signs and occlusions were present in two internal thoracic arteries each. CONCLUSIONS: This technique allows revascularization of severely and diffusely diseased coronary arteries with encouraging results.

Intermittent left coronary occlusion caused by native aortic valve thrombosis in a patient with protein S deficiency.

A 77-year-old woman presented with chest pain and cardiogenic shock. Transesophageal echocardiography showed a mobile mass occluding intermittently the left coronary ostium. The mass was surgically resected, and histologic examination revealed an organized thrombus. Coagulation study demonstrated a protein S deficiency. This is the first case of aortic thrombosis associated with protein S deficiency, and it is the first time that transesophageal echocardiography provided definite evidence that a mass can cause intermittent left ostium coronary obstruction.

Left ventricular papillary fibroelastoma: two-dimensional echocardiographic detection and surgical resection.

We report a patient with a papillary fibroelastoma arising from the left ventricular posterior wall. The tumor was detected incidentally during echocardiography undertaken to evaluate aortic stenosis. Possible complication from tumor embolization was avoided by surgical resection during aortic valve replacement.

Postinfarction atrioventricular septal rupture.

Postinfarction communication between a left ventricular aneurysm and the right atrium is a rare acquired disease. We report a case of a 72-year-old man who recently had dyspnea on minimal exertion and was found to have left ventricle-to-right atrial shunt by two-dimensional transthoracic echocardiography. This diagnosis was confirmed with transesophageal echocardiography, cardiac catheterization, and angiography. The patient underwent successful repair but died of multisystem failure. This case shows the importance of transthoracic echocardiography for the adequate diagnosis and management of such cases.
