ABSTRACT

Heart failure (HF) has high event rates, mortality, and is challenging to manage in clinical practice. Clinical management is complicated by complex therapeutic strategies in a population with a high prevalence of comorbidity and general frailty. In the last four years, an abundance of research has become available to support multidisciplinary management of heart failure from within the hospital through to discharge and primary care as well as supporting diagnosis and comorbidity management. Within the hospital setting, recent evidence supports sacubitril-valsartan combination in frail, deteriorating or de novo patients with LVEF≤40%. Furthermore, new strategies such as SGLT2 inhibitors and vericiguat provide further benefit for patients with decompensating HF. Studies with tafamidis report major clinical benefits specifically for patients with ATTR cardiac amyloidosis, a remaining underdiagnosed and undertreated disease. New evidence for medical interventions supports his bundle pacing to reduce QRS width and improve haemodynamics as well as ICD defibrillation for non-ischemic cardiomyopathy. The Mitraclip reduces hospitalisations and mortality in patients with symptomatic, secondary mitral regurgitation and ablation reduces mortality and hospitalisations in patients with paroxysmal and persistent atrial fibrillation. In end-stage HF, the 2018 French Heart Allocation policy should improve access to heart transplants for stable, ambulatory patients and, mechanical circulatory support should be considered to avoid deteriorating on the waiting list. In the community, new evidence supports that improving discharge education, treatment and patient support improves outcomes. The authors believe that this review fills the gap between the guidelines and clinical practice and provides practical recommendations to improve HF management.

ABSTRACT

BACKGROUND: Immediate coronary angiography (iCA) and primary percutaneous coronary angioplasty (pPCI) in patients successfully resuscitated after out-of-hospital cardiac arrest (OHCA) of suspected cardiac cause is controversial. Our aims were to assess the results of iCA, the prognostic impact of pPCI after OHCA, and to identify subgroups most likely to benefit from this strategy. METHODS: In this single-centre retrospective study, patients aged ≥18 years with sustained return of spontaneous circulation after OHCA and no evidence of a non-cardiac cause underwent routine iCA at admission, with pPCI if indicated. Results of iCA, and factors associated with in-hospital survival were analysed. RESULTS: Between 2006 and 2013, 160 survivors from OHCA presumed of cardiac origin were included (median age, 60 years; 85% males). iCA showed significant coronary-artery lesions in 75% of patients, and acute occlusion or unstable lesion in only 41%. pPCI was performed in 34% of patients and was not associated with survival by univariate or multivariate analysis (P=0.67). ST-segment elevation predicted acute coronary occlusion in 40%. An initial shockable rhythm was associated with higher in-hospital survival (52% vs. 19%; P<0.001). After initial defibrillation, the first rhythm recorded by 12-lead electrocardiography was highly associated with prognosis: secondary asystole had a very low survival rate (5%, 1/21) despite PCI in 43% of patients, compared to sustained ventricular tachycardia/fibrillation (42%, 15/36) and supraventricular rhythm (71%, 50/70) (P<0.001). CONCLUSIONS: In our experience, the prevalence of acute coronary occlusion or unstable lesion immediately after OHCA of likely cardiac cause is only 41%. Immediate CA in OHCA survivors, with pPCI if indicated, should be restricted to highly selected patients.

ABSTRACT

A 80-year-old man was admitted to catheterization room for an acute infero-lateral ST-elevation myocardial infarction (STEMI). Coronary angiography showed a thrombotic occlusion of the second left marginal branch, and normal other coronary arteries. The thrombo-embolic mechanism of the STEMI, and the infectious context in this patient who had had a transcatheter aortic valve implantation (TAVI) two months earlier, led us to suspect a bioprosthesis endocarditis. It was confirmed by transthoracic and transoesophageal echocardiography, which showed an aortic-mitral curtain abscess and aortic bioprosthesis vegetations, associated to Enterococcus faecalis bacteriemia. In order to specify the diagnosis, an ECG-gated multidetector CT angiography (MDCTA) had been performed. Additionally to echocardiographic findings, MDCTA showed a pseudo-aneurysm, sized 20 to 22mm, beginning from the outflow tract of the left ventricle to end on the antero-lateral face of the aorta. The patient was referred for emergency aortic bioprosthesis removal and replacement. Through this case, MDCTA showed its importance for the diagnosis and the prognostic evaluation of cardiac prosthesis endocarditis. MDCTA provided additional informations that echocardiography could not detect, because of artifacts caused by the prosthetic material and calcifications, frequent in elderly patients with comorbidities.

ABSTRACT

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.

ABSTRACT

BACKGROUND: In patients with acute ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (pPCI), the recommended times (first medical contact-to-balloon (M2B) <120 or <90min, and door-to-balloon (D2B) <45min) are reached in less than 50% of patients. PURPOSE: To compare the interventional reperfusion strategy and reperfusion times between two series of consecutive STEMI patients referred for pPCI within 12hours of symptom onset, in 2007 and 2012. METHODS: Retrospective study of 182 patients, 87 admitted from January 2007 to March 2008 (period 1), and 95 admitted from January to December 2012 (period 2). The procedural characteristics and the different times between onset of pain and mechanical reperfusion were gathered and compared by non-parametric tests. RESULTS: Radial access, thromboaspiration, and drug eluting stents were more frequent, and cardiogenic shock was less common during period 2, compared with the period 1. The median time from first medical contact to balloon (M2B) decreased by 26% (135min, [quartiles: 113-183] in 2007 versus 100 [76-137] in 2012, P<0.001), in relation to the reduction in both prehospital times and time in the catheterization laboratory (D2B: 51 [44-65] and 44min [37-55], respectively, P<0.01). CONCLUSIONS: The D2B and M2B times significantly decreased in our centre between 2007 and 2012, and reached the recommended values in >60% of the cases. This may be explained by better coordination between emergency medical units and interventional cardiologists, and by the presence of two paramedics in the catheterization laboratory for 24/24 7/7 pPCI since 2010 in France, in accordance with recent national regulation.

ABSTRACT

Since the introduction of the 64-generation scanners, the accuracy and robustness of the diagnosis of coronary artery disease has progressed. The main advantage of cardiac CT is the exclusion of coronary artery disease by its excellent negative predictive value. Currently, cardiac CT applications extend thanks to innovations both in terms of technological development systems scanner or stents implanted. This is a literature review of stent evaluation with cardiac CT.

ABSTRACT

The purpose of the study was to assess whether a strategy based on a MDCT performed routinely before CA can reduce the radiation dose during the CA, without increased global exposure in patients who need imaging of CABG. A total of 147 consecutive patients were included. The radiation dose during CA (KAP 12.1 vs 22.0 Gy/cm(2), P<.01) and the volume of iodinated contrast (155 vs 200 mL, P<.02) were reduced when preceded by a MDCT. Patients' cumulative exposures were not different in the 2 strategies (5.0 vs 5.1 mSv, P=.76). MDCT performed in first line is a valuable strategy for the assessment of CABG.

ABSTRACT

Patients with cardiac implantable electronic devices are usually excluded from MRI examinations due to contraindication for MRI. The MRI-conditional pacemaker system may allow the benefits of MRI (system 1.5T) to be more accessible to pacemaker patients. A 62-year-old man was admitted with acute coronary syndrome and atrial fibrillation. A conventional angiography showed normal coronaries. A cardiac cardioversion revealed a significant sinus node dysfunction and a magnetic resonance imaging (MRI) compatible dual chamber system was implanted. At 6-week follow-up, a cardiac MRI revealed a typical anterior myocardial infarction with diagnostic quality images despite pacemaker. This is one of the first reports of cardiovascular MRI in a patient with MRI-conditional pacing system.

ABSTRACT

BACKGROUND: Nonagenarians are systematically excluded from studies of interventional cardiology. Few data exist on the usefulness, safety, and results of coronary angiography (CA) and percutaneous coronary intervention (PCI) in this population. PURPOSE: To evaluate the benefits and hazards of CA and PCI in nonagenarians. METHODS: Retrospective study conducted from the database (Cardioreport(®)) of the CH de Versailles, from January 2001 to December 2011. RESULTS: From the 15,806 procedures performed in the center during the period, 107 (0.9%) were done in 97 patients aged ≥90years. Half of them underwent PCI. Median age was 92±2years (range: 90 to 100), 56% were women. Main indication was an acute coronary syndrome (77%, acute STEMI in 39%). The first group (n=58) had a single CA leading to strengthen medical treatment, and CABG in one case. The second group (n=49) had a CA followed by immediate (41) or delayed (8) PCI. The primary success rate of PCI was 90%. Radial route was used in 94% in the period 2009-2011 (51% overall). Failure of arterial access (4%) and difficulties of catheterization (13%) were rare. Severe complications occurred in 19%. They were local (11 hematomas, 6 severe, 4 transfusions, and 1 fatal acute ischemia of a lower limb), and general (1 stroke, 1 death by left main rupture during PCI). Twenty percent of the complications (11% of severe ones) were directly related to the procedure. Overall hospital mortality was 10%. CONCLUSIONS: Angiography is feasible in nonagenarians by radial approach without failures and with a reduced rate of complications. PCI was indicated in about half of the cases. PCI may be proposed in nonagerians with a high success rate, and an acceptable risk of local and general complications.

ABSTRACT

Since the introduction of Multi-slice computed tomography (CT), cardiac CT has been the increasingly used as a noninvasive modality for the diagnosis of coronary disease. Despite its potential benefits and promising clinical results, it has suffered from high doses of radiation associated with a risk of radiation-induced cancers. This has raised serious concerns in clinical practice. A number of strategies were then implemented to reduce the radiation dose associated with cardiac CT. The aim of this review is not to compare doses of different CT systems available on the market but to present an overview of different approaches to dose reduction and future directions.

ABSTRACT

BACKGROUND: In patients with acute ST-segment elevation myocardial infarction (STEMI), recent clinical guidelines recommend that primary percutaneous coronary intervention (PCI) should be performed within 90min of first medical contact or 45min after admission in cathlab. The Door-to-Balloon time (D2B) is widely used to measure the performance of interventional centres. AIM OF THE STUDY: To analyze the time to reperfusion in a consecutive series of STEMI patients referred for primary PCI, and to evaluate the clinical accuracy of D2B in primary PCI. METHODS: From January 2007 to March 2008, 177 patients were admitted within 12hours of a STEMI in our institution, and 87 were referred for a direct coronary angiography for primary PCI (47 by mobile medical emergency unit, 40 by the emergency department of the institution). RESULTS: The median time from first medical contact to balloon inflation (M2B) was 135min [IQR 112-183]. Recommended times were fulfilled in a minority of patients (M2B<90min: 9%,<120min: 34%). Median cathlab D2B was 51min [IQR 44-65], and was less than 45min in 34% of patients. No differences for times to reperfusion within cathlab were found between in- and off-time hours. M2B and D2B were unavailable in 23 patients (26%), because of a spontaneous TIMI 3 flow reperfusion without indication for immediate PCI in 20 patients, contra-indication for PCI in two (distal occlusion, culprit vessel diameter less than 2mm), and failure in occlusion crossing by the guide-wire in one patient. In contrast, first medical contact- or door-to-reperfusion times, assessed by a TIMI 3 flow without no-reflow in culprit artery, were available in 95% of patients, and were shorter than M2B or D2B, respectively. CONCLUSION: Although it is a feasible and reproducible process performance measure, D2B time is weakly associated with the outcome of the interventional reperfusion strategy in acute STEMI. This measure should be associated with an outcome performance measure, such as the rate of TIMI 3 flow achieved by primary PCI, or replaced by the Door-to-TIMI 3 flow reperfusion time.

ABSTRACT

The authors report a case of acute type-B aortic dissection in association with an unknown isthmic coarctation in a 30-year-old adult. Successful surgical repair was performed 6 months later without cardiopulmonary bypass. Physiopathological aspects and surgical strategy are discussed. Acute aortic dissection distal to isthmic coarctation is extremely rare and has been reported in only 5 other cases. Present case is the first, to our knowledge, to be operated without cardiopulmonary bypass.

ABSTRACT

Since its introduction as a routine arterial route for interventional cardiology, the radial route has been associated with higher X-rays doses, either to the patient and the operator. There is less evidence for this association in recent studies, probably due to the learning curve for this approach, improvement in radiological equipments and in radiation protection techniques. Coronary angiography and percutaneous coronary interventions can be performed by radial route routinely with very low levels of exposure for the patient (<50% of the reference levels). However, for a fixed dose to patient, the operator's exposure remains higher by radial route, compared to femoral route. Optimized individual radiation protection devices for operators are mandatory when procedures are performed by radial approach.

ABSTRACT

BACKGROUND: Secondary prevention is a key strategy for reducing levels of coronary heart disease, but a gap between guidelines and practice remains. OBJECTIVES: The aim of this double-part survey was to evaluate the improvement in secondary prevention one year after acute coronary syndrome (ACS) in real life, between 1999 and 2005, with respect to the change in guidelines. METHODS: Two surveys of almost similar design were performed in 1999 and 2005-2006. In each survey, unselected consecutive patients suffering from ACS (n=112 hospitalized in 1998, and n=110 in 2004) were evaluated at admission, and one year after hospitalization, for the risk factors, lifestyle, and achievement of therapeutic goals recommended by the most recent guidelines. Follow-up (FU) data were obtained by mail and phone contact with patient, general practitioner and cardiologist, and medical laboratory when appropriate. RESULTS: At 1-year FU (n=192 survivors with FU), smoking cessation (87% in 1999 versus 89% in 2005) and obesity (13% versus 19%, respectively) did not vary significantly. Blood pressure was controlled (< 140/90 mmHg, excepted in diabetics in 2005 with less than 130/80 mmHg) in 65% versus 80% (p<0.03). The rate of patients with no or controlled diabetes mellitus decreased from 1999 to 2005 (90% versus 76%), despite more intensive treatment (insulin in 1% versus 20%).The goals for LDL cholesterol were achieved in 47% of patients in 1999 (< 3.4 mmol/L) and in 76% in 2005 (< 2.6 mmol/L) (p<0.0001). Goals for triglycerides were achieved in 86% in 1999 (< 2g/L), and in 80% in 2005 (< 1.5 g/L) (NS). Besides, 63% of patients received an hypolipemic drug in 1999 (a statin in 59%) and 91% in 2005 (a statin in 88%). Mean number of controlled risk factors was 3.96+/-1.52 in 1999 versus 4.94+/-1.83 in 2005, and prevalence of pts with more than five controlled risk factors at one year FU increased from 15 to 44% (p<0.0001). CONCLUSIONS: These results, drawn from unselected consecutive patients managed in real life, demonstrate an improvement in secondary prevention one year after ACS, between 1999 and 2005, despite strengthened guidelines for blood pressure, triglycerides and LDL cholesterol levels. Control of obesity and diabetes remains unoptimal.

ABSTRACT

X-ray exposure of patient during coronary angiography (CA) and percutaneous transluminal coronary angioplasty (PTCA) may have some deleterious effects. The dose area product (DAP), related to the effective dose, is a measure of stochastic risk and a potential quality indicator. The aim of our study was to assess radiation exposure of patients in a large series of "real life" interventional cardiac procedures. We evaluated DAP and Fluoroscopy time (t) during CA and/or PTCA in 3600 consecutive patients from 2002 to 2005. Procedures were performed by five experienced physicians, using successively femoral and radial techniques. DAP and t significantly correlated (r = 0.73; p < 0.0001). Median [25th-75th percentiles] values for DAP and for t were 63 [40-101] Gy.cm2 and 6.3 [4-10] min for CA, 100 [62-178] Gy.cm2 and 14.0 [9-22] min for elective PTCA, and 141 [90-219] Gy.cm2 and 15.7 [11-23] min for CA immediately followed by ad hoc PTCA, respectively. Differences between operators ranged from 50% (CA) to 70% (PTCA) for both DAP and t (p < 0.001). Moving from the femoral to the radial approach resulted in a 1.5 to 2-fold increase in DAP in 2002 (p < 0.001). DAP and t then decreased toward the european DIMOND reference values (in 2005: 53.4 Gy.cm2 and 5.5 min for CA, 104.64 Gy.cm2 and 13.1 min for elective PTCA, 128.4 Gy.cm2 and 13.6 min for ad hoc PTCA). In conclusion, radiation exposure to patients and staff are strongly dependent on operators, time course, and the arterial access, due in part to the learning curve for radial approach. The enhanced knowledge of radiation dose is the first step of a radiation dose-reduction program, likely to minimize patient and operator radiation hazards in interventional cardiology. Definition of national reference values for DAP and fluoroscopy time would be helpful for appropriate comparisons.
