0218: Comparison of transvenous versus surgical implantation of left ventricular lead for cardiac resynchronization therapy
BackgroundApproximately 1% of the adult population have heart failure with reduced ejection fraction. Since the 1980s, therapeutic advances in this field have been significant, particularly through the development of cardiac resynchronization therapy (CRT). However, transvenous implantation of the left ventricular (LV) lead is unsuccessful in 5 - 15% of patients. For this group, surgical placement of LV lead is an alternative.ObjectiveCompare the effects of transvenous versus surgical implantation of the LV lead in CRT.MethodsWe included 100 consecutive patients who had received CRT in our centre between January 2008 and July 2012 in a retrospective observational study. Twelve patients who had failed transvenous implantation of LV lead had a surgical placement.ResultsPopulation characteristics were a mean age of 66±11 years, 16% female, New York Heart Association class 2.9±0.5, 45% ischemic cardiomyopathy, left ventricular ejection fraction (LVEF) 24±7%, QRS width 165±23ms. There were no major difference in preoperative variables between two groups except sex category (12.5% female in transvenous group versus 42% in surgical group, p=0.022). During a mean follow-up of 508±429 days, the improvements seen in all variables showed no difference between the groups. At six months, 77% of patients had improved at least one class of their dyspnea stage, LVEF improved significantly (24±7% versus 36±10% at six months).ConclusionsSurgical placement of LV lead offers similar benefits as compared with transvenous implantation
212: Death and cardiovascular events in patients with acute coronary syndrome and abdominal aortic aneurysm
BackgroundAbdominal aortic aneurysm (AAA) is associated with peripheral and coronary artery disease (CAD), however little is known about the prognosis of patients who experienced an acute coronary syndrome (ACS) and have an AAA. The aim of this study was to assess the prevalence of AAA in patients hospitalized for ACS and to evaluate it was associated with an increased cardio-vascular (CV) risk during follow up.MethodsBetween February 1, 2008 and March 30, 2009, patients admitted for ACS with significant (â„50% stenosis) coronary lesions underwent echography to check for presence of AAA. The AAA was defined as dilation of infrarenal aorta with maximum antero-posterior diameter â„30mm. During a 2 years follow-up we recorded all causes death, CV death and non-fatals CV events. The combination of CV death and CV non-fatals events was defined as the primary endpoint.ResultsAmong 306 patients, 20 AAAs (6,6%) were diagnosed, of average (±sd) diameter 33±3.7mm, with a maximum diameter of 45mm, non requiring surgery. Follow-up at 2 years was available for 292 patients (95,7%). During follow-up, 77 patients (25,5%) experienced an event (all causes death or non-fatals CV event) : 23 deaths (7,6%), of wich 16 were from CV cause, and 55 non-fatals CV event (18,2%). No event was due to AAA. In univariate analysis age, abdominal aortic diameter, diabetes mellitus, previously known CAD and AAA were significantly associated with fatal and non-fatal CV event (p<0,05). In multivariate analysis, age (OR=1.03; 95%CI (1.008,1.058), diabetes mellitus (OR=1.7; 95%CI (1.05,2.7) and AAA (OR=3.2; 95%CI (1.24,8.44) were independantly associated with the risk of fatal or non-fatal CV event. Age (OR=1.18 95%CI (1.10,1.26) and AAA (OR=4.17 95%CI (1.17,14.9) were the only independant predictors of all causes death.ConclusionOur results show that in patients with CAD, the presence of small non surgical AAA is associated with worse CV prognosis and higher all causes mortality at 2 years
Symptomatic and Asymptomatic Neurological Complications of Infective Endocarditis: Impact on Surgical Management and Prognosis
International audienceObjectives:Symptomatic neurological complications (NC) are a major cause of mortality in infective endocarditis (IE) but the impact of asymptomatic complications is unknown. We aimed to assess the impact of asymptomatic NC (AsNC) on the management and prognosis of IE.Methods: From the database of cases collected for a population-based study on IE, we selected 283 patients with definite left-sided IE who had undergone at least one neuroimaging procedure (cerebral CT scan and/or MRI) performed as part of initial evaluation.Results Among those 283 patients, 100 had symptomatic neurological complications (SNC) prior to the investigation, 35 had an asymptomatic neurological complications (AsNC), and 148 had a normal cerebral imaging (NoNC). The rate of valve surgery was 43% in the 100 patients with SNC, 77% in the 35 with AsNC, and 54% in the 148 with NoNC (p<0.001). In-hospital mortality was 42% in patients with SNC, 8.6% in patients with AsNC, and 16.9% in patients with NoNC (p<0.001). Among the 135 patients with NC, 95 had an indication for valve surgery (71%), which was performed in 70 of them (mortality 20%) and not performed in 25 (mortality 68%). In a multivariate adjusted analysis of the 135 patients with NC, age, renal failure, septic shock, and IE caused by S. aureus were independently associated with in-hospital and 1-year mortality. In addition SNC was an independent predictor of 1-year mortality.Conclusions The presence of NC was associated with a poorer prognosis when symptomatic. Patients with AsNC had the highest rate of valve surgery and the lowest mortality rate, which suggests a protective role of surgery guided by systematic neuroimaging results
Why Are Outcomes Different for Registry Patients Enrolled Prospectively and Retrospectively? Insights from the Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF).
Background: Retrospective and prospective observational studies are designed to reflect real-world evidence on clinical practice, but can yield conflicting results. The GARFIELD-AF Registry includes both methods of enrolment and allows analysis of differences in patient characteristics and outcomes that may result. Methods and Results: Patients with atrial fibrillation (AF) and â„1 risk factor for stroke at diagnosis of AF were recruited either retrospectively (nâ=â5069) or prospectively (nâ=â5501) from 19 countries and then followed prospectively. The retrospectively enrolled cohort comprised patients with established AF (for a least 6, and up to 24 months before enrolment), who were identified retrospectively (and baseline and partial follow-up data were collected from the emedical records) and then followed prospectively between 0-18 months (such that the total time of follow-up was 24 months; data collection Dec-2009 and Oct-2010). In the prospectively enrolled cohort, patients with newly diagnosed AF (â€6 weeks after diagnosis) were recruited between Mar-2010 and Oct-2011 and were followed for 24 months after enrolment. Differences between the cohorts were observed in clinical characteristics, including type of AF, stroke prevention strategies, and event rates. More patients in the retrospectively identified cohort received vitamin K antagonists (62.1% vs. 53.2%) and fewer received non-vitamin K oral anticoagulants (1.8% vs . 4.2%). All-cause mortality rates per 100 person-years during the prospective follow-up (starting the first study visit up to 1 year) were significantly lower in the retrospective than prospectively identified cohort (3.04 [95% CI 2.51 to 3.67] vs . 4.05 [95% CI 3.53 to 4.63]; pâ=â0.016). Conclusions: Interpretations of data from registries that aim to evaluate the characteristics and outcomes of patients with AF must take account of differences in registry design and the impact of recall bias and survivorship bias that is incurred with retrospective enrolment.

Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.
BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

Simple scoring system to predict in-hospital mortality after surgery for infective endocarditis
BACKGROUND:
Aspecific scoring systems are used to predict the risk of death postsurgery in patients with infective endocarditis (IE). The purpose of the present study was both to analyze the risk factors for in-hospital death, which complicates surgery for IE, and to create a mortality risk score based on the results of this analysis.
METHODS AND RESULTS:
Outcomes of 361 consecutive patients (mean age, 59.1\ub115.4 years) who had undergone surgery for IE in 8 European centers of cardiac surgery were recorded prospectively, and a risk factor analysis (multivariable logistic regression) for in-hospital death was performed. The discriminatory power of a new predictive scoring system was assessed with the receiver operating characteristic curve analysis. Score validation procedures were carried out. Fifty-six (15.5%) patients died postsurgery. BMI >27 kg/m2 (odds ratio [OR], 1.79; P=0.049), estimated glomerular filtration rate 55 mm Hg (OR, 1.78; P=0.032), and critical state (OR, 2.37; P=0.017) were independent predictors of in-hospital death. A scoring system was devised to predict in-hospital death postsurgery for IE (area under the receiver operating characteristic curve, 0.780; 95% CI, 0.734-0.822). The score performed better than 5 of 6 scoring systems for in-hospital death after cardiac surgery that were considered.
CONCLUSIONS:
A simple scoring system based on risk factors for in-hospital death was specifically created to predict mortality risk postsurgery in patients with IE
