Introduction Chronic inflammation promotes aortic valve calcification. It is known that epicardial fat is a source of inflammation. The aim of this study was to investigate the relationship between epicardial fat thickness, cardiac conduction disorders and outcomes in patients undergoing transcatheter aortic valve implantation (TAVI). Methods During a three-year period, 45 patients with severe aortic stenosis who underwent TAVI were recruited to the study. Data were collected retrospectively. Epicardial fat was defined as the adipose tissue between the epicardium and the visceral pericardium. Mean epicardial fat thickness was determined by multi-slice computed tomography, which was performed before the procedure. Results The average thickness of epicardial fat was 13.06 ± 3.29 mm. This study failed to reveal a significant correlation between epicardial fat thickness and post-procedural left bundle branch block, right bundle branch block, paravalvular aortic regurgitation and pacemaker implantation rates (p > 0.05). Conclusions The results of this study failed to show a significant relationship between epicardial fat thickness, cardiac conduction disorders and outcomes, however further studies with larger sample numbers are required to explore the relationship.

Rheumatoid valve disease is a general health problem of developing countries, and it mainly affects after the age of 40. Assessment of the correct mitral valve area (MVA) is important for the treatment of rheumatoid valve disease. However, there are contradictions between the three-dimensional (3D) and two-dimensional (2D) methods. A measurement with 3D echocardiography is a more accurate method to measure the MVA. However, in centers without 3D echocardiography, there are some difficulties in the accurate measurement of the MVA. The aim of this study was to assess the value of 2D transesophageal echocardiography (TEE) mitral valve vena contracta area (VCA) in predicting the severity of rheumatoid mitral stenosis (RMS) by comparing 3D planimetry. A total of 24 patients (10 females and 14 males) who were diagnosed with mild/moderate/severe RMS with using pressure half time, mean transmitral gradient, and planimetry methods were included in this study. 3D images were acquired using the 3D zoom and full volume. 2D TEE VCA was measured at an angle of 140° and 60°, which was perpendicular to the former, with color Doppler and the VCA was measured with an ellipsoid area using mathematical formula. There was statistically significant relationship between the measurements of 2D VCA and 3D zoom mode MVA planimetry and MVA full measurements (MVA full volume) (p

We prospectively assessed the value of estimated glomerular filtration rate (eGFR) by the Modification of Diet in Renal Disease (MDRD) and Cockcroft-Gault (C-G) equations in predicting inhospital adverse outcomes after primary coronary intervention for acute ST-segment elevation myocardial infarction. We classified 647 patients into 3 categories according to eGFR, 90 mL/min/1.73 m2. The eGFRC-G classified 17 patients in the >90 mL/min/1.73 m2 subgroup and 6 and 11 patients in the 60 to 90 and 2 subgroups, respectively. In multivariate analysis, patients with eGFRC-G < 60 mL/min/1.73 m2 had 19.5-fold (95% confidence interval [CI] 1.55-178) higher mortality risk and 5.48-fold (95% CI 1.75-24.21) higher major adverse cardiac events risk compared to patients with eGFRC-G >90 mL/min/1.73 m2 ( P = .01 and P = .01, respectively); the eGFRMDRD was not predictive. Although the MDRD equation more accurately estimates GFR in certain populations, the CG formula may be a better predictor of adverse events.

WOS: 000417874800004, PubMed ID: 29076824, Objective: The present study was designed to evaluate the characteristics of pulmonary hypertension (PH) and adult cardiology practice patterns for PH in our country. Methods: We evaluated preliminary survey data of 1501 patients with PH (females, 69%; age, 44.8 +/- 5.45) from 20 adult cardiology centers (AdCCs). Results: The average experience of AdCCs in diagnosing and treating patients with PH was 8.5 +/- 3.7 years. Pulmonary arterial hypertension (PAH) was the most frequent group (69%) followed by group 4 PH (19%), group 3 PH (8%), and combined pre- and post-capillary PH (4%). PAH associated with congenital heart disease (APAH-CHD) was the most frequent subgroup (47%) of PAH. Most of the patients' functional class (FC) at the time of diagnosis was III. The right heart catheterization (RHC) rate was 11.9 +/- 11.6 per month. Most frequently used vasoreactivity agent was intravenous adenosine (60%). All patients under targeted treatments were periodically for FC, six-minute walking test, and echo measures at 3-month intervals. AdCCs repeated RHC in case of clinical worsening (CW). The annual rate of hospitalization was 14.9 +/- 19.5. In-hospital use of intravenous iloprost reported from 16 AdCCs in CWs. Bosentan and ambrisentan, as monotreatment or combination treatment (CT), were noted in 845 and 28 patients, respectively, and inhaled iloprost, subcutaneous treprostinil, and intravenous epoprostenol were noted in 283, 30, and four patients, respectively. Bosentan was the first agent used for CT in all AdCCs and iloprost was the second. Routine use of antiaggregant, anticoagulant, and pneumococcal and influenza prophylaxis were restricted in only two AdCCs. Conclusion: Our nationwide data illustrate the current status of PH regarding clinical characteristics and practice patterns.

Valve thrombosis is an important problem of surgical valves and also newer generation transcatheter valves. Valve thrombosis has been reported in different transcatheter valves, such as Edwards and Corevalve valves. Valve thrombosis after Lotus valve implantation has not been reported. To the best of our knowledge, this is the first report in the literature of a Lotus valve thrombosis. The patient discharged home on aspirin and clopidogrel after procedure, however she became symptomatic soon and the diagnosis of prosthetic valve malfunction due to thrombosis was made. Patient treated with anticoagulant therapy.

Objective: A predictive role of serum Pentraxin 3 (PTX3) for short-term adverse cardiovascular events including mortality in acute myocardial infarction (AMI) was reported in recent studies. The aim of the study was to investigate long-term prognostic significance of serum PTX3 in an AMI with 5-year follow-up period in this study. Methods: In this prospective study, 140 patients, who were admitted to the emergency department between January 2011 and December 2011 with acute chest pain and/or dyspnea and diagnosed with AMI and 60 healthy controls were included. PTX3 levels were measured at admission by using an ELISA method. The study group was divided into tertiles on the basis of admission PTX3 values: the high-PTX3 group (≥4.27 ng/mL), the middle-PTX3 groups (4.27–1.63 ng/mL), and the low-PTX3 group (≤1.63 ng/mL). Results: PTX3 level was significantly more greatly increased in the AMI group than in the controls (2.27±0.81 vs. 0.86±0.50 ng/mL, p

Isolated left ventricular noncompaction (LVNC) is a rare hereditary cardiomyopathy characterized by prominent intraventricular trabeculations separated by deep intertrabecular recessus. While cardiac ischemia due to microvascular dysfunction is common in these patients, ST-segment elevation myocardial infarction (STEMI) is rare and usually seen as a consequence of coincidental coronary artery disease. We report the case of a 20 year-old male patient admitted to our emergency department with a complaint of squeezing chest pain who was subsequently diagnosed with STEMI according to electrocardiographic findings, although an emergent coronary angiogram demonstrated normal coronary arteries. Echocardiography revealed isolated LVNC, and the diagnosis was confirmed via magnetic resonance imaging. Repeat coronary catheterization with acetylcholine infusion and coronary flow reserve measurement failed to demonstrate vasospasm or microvascular dysfunction. As no apparent cause was found, this case was designated ‘idiopathic’ myocardial infarction. Coronary thromboembolism due to stagnation of blood in the left ventricular cavity remained as the most probable mechanism underlying myocardial infarction.

No:25, Haydarpasa, Istanbul, Tel. 0216 4445257 Email. tsguvenc@gmail.com Gelis Tarihi: 28.04.2011 • Kabul Tarihi: 13.05.2011 ABSTRACT Clozapine is an atypical antipsychotic drug used in the treatment of schizophrenia. Cardio toxicity in therapeutic doses is an important concern for the safety of the drug, as there are reported cases of myocarditis, pericarditis and cardiomyopathy following clozapine use. Our aim is to report a rare, but important cause of chest pain in a schizophrenia patient. A 20 year-old male with schizophrenia and on clozapine treatment admitted to our hospital and he was diagnosed with acute pericarditis based on the clinical examination, electrocardiographic and echocardiographic fi ndings. Discontinuation of clozapine resulted in remission of the signs and symptoms within 5 days. Although acute pericarditis is the rarest manifestation of clozapine cardio toxicity it is important in clinical practice. Failure to recognize may result with serious consequences, including pericardial tamponade and fulminant myocarditis.

Pericardial cyst is a rare congenital anomaly that is usually diagnosed during evaluation for right-sided heart failure. We report a 50-year-old man with a primary diagnosis of ST-segment elevation myocardial infarction at admission, whose emergent angiography revealed a calcific mass close to right coronary artery. Further analysis of the mass with computed tomography and three-dimensional echocardiography revealed a giant pericardial cyst causing partial obstruction of superior vena cava. Unlike previous cases reported, the patient had no symptoms compatible with right-sided heart failure.

Introduction Isolated left ventricular noncompaction is a rare form of cardiomyopathy. Heart failure with deteriorated systolic function is the hallmark of this cardiomyopathy. Albeit it may cause ventricular tachycardia (VT) and systemic embolism, it is a rarity to see these complications in a patient with noncompaction and normal systolic functions. Case report A 78-year old female patient with a history of cerebrovascular accident admitted to our hospital with palpitation and subsequently developed cardiopulmonary arrest. Her ECG showed ventricular tachycardia degenerated into fibrillation. Echocardiography and cardiac magnetic resonance (CMR) revealed a small noncompacted segment in left ventricular apex. Ventricular tachycardia was induced in electrophysiologic study and an implantable cardioverter–defibrillator was implanted. Discussion Patients with isolated left ventricular noncompaction usually present with heart failure symptoms and subsequently diagnosed with echocardiography. Rarely, it may cause ventricular tachycardia and systemic embolism in a patient with normal systolic functions and a small noncompacted segment. Noncompaction should be carefully sought in unexplained ventricular tachycardia and cerebrovascular accidents, even if heart failure is not present.

Background Management of aortic regurgitation depends on the assessment for severity. Echocardiography remains as the most widely available tool for evaluation of aortic regurgitation. In this manuscript, we describe a novel parameter, jet length/velocity ratio, for the diagnosis of severe aortic regurgitation. Methods and Results A total of 30 patients with aortic regurgitation were included to this study. Severity of aortic regurgitation was assessed with an aortic regurgitation index incorporating five echocardiographic parameters. Jet length/velocity ratio is calculated as the ratio of maximum jet penetrance to mean velocity of regurgitant flow. Jet length/velocity ratio was significantly higher in patients with severe aortic regurgitation (2.03 ± 0.53) compared to patients with less than severe aortic regurgitation (1.24 ± 0.32, P

Purpose Ventricular noncompaction/hypertrabeculation (NC/HT) is a rare form of congenital cardiomyopathy. We aimed to investigate the presence of serum tenascin-C (TN-C) in adult patients with NC/HT and evaluate its value. Methods and Results Serum TN-C levels were measured by ELISA in 50 NC/HT patients both with/without systolic dysfunction and in 23 normal controls. Systolic dysfunction was defined as ejection fraction (EF) ≤ 40. Mann–Whitney U-test and ROC curve analysis were done. Of 49 NC/HT patients, 24 (49%) patients had systolic dysfunction (mean age 36 ± 15) and 25 patients (51%) had normal systolic function (mean age 36 ± 17). The ages between groups were not different. The mean levels of serum TN-C in patients with or without systolic dysfunction were 26 ± 10 ng/mL and 26 ± 8 ng/mL respectively, compared to normal controls, 7 ± 2 ng/mL (P

PP-309 The aim of this study was to investigate the prognostic value of Gensini score in 3-year clinical outcomes in patients undergoing primary percutaneous coronary intervention (pPCI) for acute ST-elevation myocardial infarction (STEMI). The present study prospectively included 114 consecutive

Background: The Zwolle score (Zs) is a validated risk score used to identify low-risk patients with acute ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). The Syntax score (Ss) is an angiographic score that evaluates the complexity of coronary artery disease. Aim: We aimed to create a simple risk score by combining these two scores for risk stratification in patients with STEMI undergoing primary PCI. Methods: 299 consecutive STEMI patients (mean age 57.4 ± 11.7 years, 240 men) who underwent primary PCI were prospectively enrolled into the present study. The study population was divided into tertiles based on admission Zs and Ss. A high Zs (> 3) and high Ss (> 24) were defined as values in the third tertiles. A low Zs and low Ss were defined as values in the lower two tertiles. Patients were then classified into four groups: high Zs and high Ss (HZsHSs, n = 26), high Zs and low Ss (HZsLSs, n = 29), low Zs and high Ss (LZsHSs, n = 48), and low Zs and low Ss (LZsLSs, n = 196). In-hospital cardiacoutcomes were then recorded.Results: In-hospital cardiovascular mortality was higher in HZsHSs (50%) compared to the HZsLSs (27.5%), LZsHSs (0%), and LZsLSs (0.5%) groups. After adjustment for potentially confounding factors, HZsHSs (OR 77.6, 95% CI 6.69–113.1, p = 0.001), and HZsLSs (OR 28.9, 95% CI 2.77–56.2, p = 0.005) status, but not LZsHSs and LZsLSs status, remained independent predictors of in-hospital cardiovascular mortality. Conclusions: STEMI patients with HZsHSs represent the highest risk population for in-hospital cardiovascular mortality.

Background: Clinical outcomes of patients with myocardial infarction are primarily determined by the successful restoration of myocardial reperfusion and the severity of coronary atherosclerosis. Aim: To investigate the predictive value of Gensini score on ST-segment resolution (STR) in patients undergoing primary percutaneous coronary intervention (pPCI) for acute ST-elevation myocardial infarction (STEMI). Methods: The present study prospectively included 114 consecutive patients (mean age 54 ± 10 years, 15 women) with STEMI who underwent successful pPCI. Sum of ST-segment elevation amount in millimetres was obtained before angioplastyand 60 min after pPCI. ΣSTR < 50% was accepted as a ECG sign of no-reflow phenomenon. Thrombus grading was calculated according to the results of coronary angiography, and Gensini score (GS-pPCI) was calculated after pPCI without incorporating culprit lesion. Patients were divided into two groups according to STR: those with STR(–), and those with STR(+). Patients were also analysed according to the infarct-related artery. Results: GS-pPCI was significantly higher in patients with STR(–) (10.1 ± 11.8 vs. 22 ± 18.6, p = 0.005). GS-pPCI was inversely correlated with STR (r = –0.287, p = 0.002). In subgroup analysis, patients in the STR(–) group with culprit lesion in left anterior descending artery and left circumflex artery also showed higher GS-pPCI (10.9 ± 13.5 vs. 23.5 ± 21.3, p = 0.03 and 9.6 ± 8.7 vs. 24.1 ± 21, p = 0.04, respectively). High thrombus burden was also observed more frequently in patients with STR(–) (68% vs. 43%, p = 0.03). Multivariate logistic regression analysis demonstrated that GS-pPCI and high thrombus burden independently predicted inadequate STR (OR 1.07, 95% CI 1.03–1.12, p = 0.001 and OR 3.28, 95% CI1.11–9.72, p = 0.03, respectively).Conclusions: GS-pPCI and high thrombus burden play an important role in predicting inadequate STR in patients with STEMI treated with pPCI.

Background: Resistin is a novel adipokine that is suggested to be involved in inflammatory conditions and atherosclerosis. Aim: To investigate the prognostic importance of resistin in acute myocardial infarction (AMI) patients. Methods: Resistin levels were measured in a population of 132 patients with AMI, of whom 72 (54%) had a diagnosis of ST elevation myocardial infarction (STEMI), and 60 (46%) had non-ST elevation myocardial infarction (NSTEMI). Thirty-three consecutive subjects who were referred to elective coronary angiography due to chest pain evaluation with normal coronary angiograms served as controls. All patients were followed-up for the occurrence of major adverse cardiac events (MACE). Results: There was a significant increase in serum resistin levels in patients with AMI compared to controls (3.71 ± 4.20 vs. 2.00 ± 1.05, p = 0.001, respectively). However, serum resistin levels were similar in patients with STEMI and NSTEMI. (4.26 ± 5.11 vs. 3.06 ± 2.64, p = 0.49, respectively). The patients with MACE had significantly higher levels of serum resistin levels compared to either the AMI or the control group (6.35 ± 5.47, p = 0.005, respectively). Logistic regression analysis revealed that resistin, left ventricular ejection fraction, and coronary artery bypass graft were independent predictors of MACE in AMI patients (OR = 1.11, 95% CI 1.01–1.22, p = 0.03 and OR = 3.84, 95% CI 1.26–11.71, p = 0.018, respectively). Conclusions: Serum resistin level was increased in patients with AMI and constituted a risk factor for MACE in this group.

Background: Presence of Metabolic Syndrome (MetS) has been shown to predict higher risk for cardiovascular diseases. However, in patients with ST Segment Elevation Myocardial Infarction (STEMI), prognostic importance of MetS has not been widely studied. Methods: We prospectively recruited 611 STEMI patients (521 male, 90 female) who were treated by primary angioplasty. Metabolic syndrome was diagnosed according to the International Diabetes Federation metabolic syndrome worldwide definition. Coronary angiographic data and in-hospital events of individuals were recorded. Major Adverse Cardiac Events (MACE) included cardiac death, recurrent myocardial infarction and target lesion revascularization. Results: Metabolic syndrome group included 276 (45.1% of the study cohort; mean age 56.8 ± 12.2; 210 male) and control group included 335 subjects (54.9% of the study cohort; mean age 55.6 ± 12.9; 311 male). The frequency of female gender, hypertension, Diabetes Mellitus (DM), hyperlipidemia and positive history for coronary artery disease were higher in MetS group, whereas, the ratio of smokers was higher in the control group. The incidence of in-hospital death and MACE was not statistically different in MetS and control groups. Presence of MetS was not correlated with in-hospital death and MACE in univariate analysis. In multivariate analysis using model adjusted for age, gender, DM/ fasting glucose >100 mg/dL, left ventricular ejection fraction, post-PCI TIMI flow grade

Introduction Pulmonary vasculature is affected in patients with chronic pulmonary obstructive disease (COPD). As a result of increased pulmonary resistance, right ventricular morphology and function are altered in COPD patients. High altitude and related hypoxia causes pulmonary vasoconstriction, thereby affecting the right ventricle. We aimed to investigate the combined effects of COPD and altitude-related chronic hypoxia on right ventricular morphology and function. Materials and Methods Forty COPD patients living at high altitude (1768 m) and 41 COPD patients living at sea level were enrolled in the study. All participants were diagnosed as COPD by a pulmonary diseases specialist depending on symptoms, radiologic findings and pulmonary function test results. Detailed two-dimensional echocardiography was performed by a cardiologist at both study locations. Results Oxygen saturation and mean pulmonary artery pressure were higher in the high altitude group. Right ventricular end diastolic diameter, end systolic diameter, height and end systolic area were significantly higher in the high altitude group compared to the sea level group. Parameters of systolic function, including tricuspid annular systolic excursion, systolic velocity of tricuspid annulus and right ventricular isovolumic acceleration were similar between groups, while fractional area change was significantly higher in the sea level groups compared to the high altitude group. Indices of diastolic function and myocardial performance index were similar between groups. Conclusion An increase in mean pulmonary artery pressure and right ventricular dimensions are observed in COPD patients living at high altitude. Despite this increase, systolic and diastolic functions of the right ventricle, as well as global right ventricular performance are similar in COPD patients living at high altitude and sea level. Altitude-related adaptation to chronic hypoxia could explain these findings.

Pulmonary hypertension is caused by a heterogenous group of disorders with diverse pathophysiological mechanisms, with ultimate structural changes in the pulmonary vascular bed. Platelet activation plays an important role in the development of pulmonary arterial hypertension, while it is unknown whether it contributes to pathogenesis in other conditions. We aimed to investigate platelet activation in different causes of pulmonary hypertension by means of mean platelet volume measurement.A total of 67 patients with different causes of pulmonary hypertension, and 31 controls, were retrospectively reviewed. Patients with pulmonary hypertension were further grouped according to underlying disease, including pulmonary arterial hypertension, pulmonary hypertension due to left ventricular failure, and pulmonary hypertension due to chronic obstructive pulmonary disorder. All patients and controls past medical data, admission echocardiograms and complete blood counts were reviewed.Patients with pulmonary hypertension had higher mean platelet volume levels compared to healthy controls (8.77 ± 1.18 vs 7.89 ± 0.53; p0.001), and statistical significance was still present when pulmonary arterial hypertension patients were not included in the pulmonary hypertension group (8.59 ± 1.23 vs 7.89 ± 0.53; p0.001). Among patients with pulmonary hypertension, the pulmonary arterial hypertension group and the pulmonary hypertension due to left ventricular failure group had higher mean platelet volumes compared to healthy controls. Mean platelet volume did not correlate with pulmonary artery pressure.Our results indicate that mean platelet volume is not only elevated in pulmonary arterial hypertension, but also due to other causes of pulmonary hypertension.

Background Aortic dissection is an important cause of acute chest pain that should be rapidly diagnosed, as mortality increases with each hour this condition is left untreated. The diagnosis can be challenging, especially if concomitant myocardial infarction is present. Echocardiography is an important tool for the differential diagnosis. Objectives To stress the importance of recognizing aortic regurgitation for the differentiation of myocardial infarction and aortic dissection. Case Report An 80-year-old woman was admitted to our hospital with chest pain that was diagnosed as inferior and lateral wall myocardial infarction based on electrocardiographic findings. The diagnosis was reevaluated when aortic regurgitation was detected on echocardiography. Closer inspection of the ascending aorta revealed a dissection flap as the cause of aortic regurgitation. Conclusion Detection of aortic regurgitation in a patient with myocardial infarction and normal valves should prompt the search for a possible aortic dissection, whether or not the dissection flap can be visualized.

Objective: To determine the subclinical effects of isolated obesity and its duration on cardiac function by using routine echocardiography and tissue Doppler myocardial strain rate. Methods: Forty-nine subjects were enrolled in this study; 29 with isolated obesity defined as a body mass index ≥30 kg/m2 with no other cardiovascular comorbidities, and 20 nonobese controls. All subjects underwent two-dimensional and Doppler echocardiography including tissue Doppler imaging and myocardial strain rate. Results: The average duration of obesity was 12.1 years (4–18 years). Abnormalities of left ventricular (LV) wall thickness, mass, diastolic function, and left atrial size were detected in obese individuals, despite having preserved ejection fractions. The LV global longitudinal peak strain rate was significantly lower in obese subjects compared to nonobese control subjects (1.07 ± 0.14 vs. 1.38 ± 0.12, P < 0.001). Using multivariate analysis, the duration of obesity (s=−0.76, P < 0.001), body mass index (s=−0.35, P = 0.023), and age (s=−0.29, P = 0.009) were independent predictors of the decreased LV global longitudinal peak strain rate, while the duration of obesity (s=−0.66, P < 0.001) and body mass index (s=−0.28, P = 0.037) were independent predictors of the decreased right ventricular (RV) peak strain rate. Conclusion: The presence and the duration of obesity were associated with impairment of subclinical biventricular systolic and diastolic function. These findings have the potential to increase awareness of subclinical cardiac manifestations in patients with isolated obesity and influence their early management.

The relationship between epicardial adipose tissue (EAT) and coronary artery disease has been predominantly demonstrated in the last two decades. The aim of this study was to investigate the predictive value of EAT thickness on ST-segment resolution that reflects myocardial reperfusion in patients undergoing primary percutaneous coronary intervention (pPCI) for acute ST-segment elevation myocardial infarction (STEMI). The present study prospectively included 114 consecutive patients (mean age 54 ± 10 years, range 35-83, 15 women) with first acute STEMI who underwent successful pPCI. ST-segment resolution (ΔSTR)

OP-153 Ventricular Hypertrabeculation/Noncompaction (HT/NC) is a rare form of congenital cardiomyopathy which may be associated with heart failure, arrhythmia and embolic events. Abnormal heart rate turbulence (HRT) and T wave alternans (TWA) is strong independent predictors of sudden cardiac
