Article | 2005 | European Journal of General Medicine2 ( 3 ) , pp.129 - 131

This paper reports a 74 year-old-man with a hypertrophic cardiomyopathy associated with mid-ventricular obstruction and a secundum type atrial septal defect. He had been suffering from shortness of breath and occasional attacks of dizziness. Doppler echocardiography revealed the gradient in the mid-left ventricular area. A transesophageal echocardiogram confirmed the findings of transthoracic study and an ostium secundum-type atrial septal defect was documented. The present case represents a rare combination of hypertrophic cardiomyopathy associated with midventricular obstruction, and an ostium secundum type atrial septal defect in . . . an elderly man Daha fazlası Daha az

Purpose: the aim of this study is to investigate whether P wave dispersion (PWD), measured before, during and after fibrinolytic therapy (FT,) is able to predict successful reperfusion and infarct related artery (IRA) patency in patients with acute anterior MI who received FT. Methods: Sixty-eight patients who presented with acute anterior MI were enrolled in the study. An electrocardiogram was performed before and at 30, 60, 90 and 120 minutes after the start of FT. PWD was defined as the difference between maximum and minimum P wave duration on standard 12-lead surface electrocardiogram. A multivariate logistic regression model wa . . .s used to assess whether PWD was predictor of IRA patency and STsegment resolution (STR) on electrocardiogram. Results: PWD 120 was significantly lower in patients with STR on electrocardiogram (38 patients) compared with those without STR (30 patients) (44.8±11.5 vs. 52.9±10.3 ms; p<0.001). PWD 120 was found to be significantly lower in patients with patent IRA (31 patients) compared to those with occluded IRA (37 patients) (42.3±9.7 vs. 53.5±10.6 ms; p<0.001). Logistic regression analysis revealed that PWD120 significantly predicted STR and IRA patency. A ?51.6 ms PWD 120 can predict an occluded IRA with a 87% sensitivity, ?51 ms PWD 120 can predict no reperfusion with a 74% sensitivity. Conclusion: PWD values, which were higher than 51 ms and 51.6 ms in patients who received fibrinolytic therapy, can serve as a marker of failed reperfusion and occluded IRA. PWD values, in combination with other reperfusion parameters, can contribute to the identification of rescue PCI candidates. © 2012 CIM Daha fazlası Daha az

A rare complication during oxcarbazepine use,complete atrioventricular block: Case report

Karabag T. | Aydin M. | Dogan S.M.

Article | 2013 | Turkiye Klinikleri Cardiovascular Sciences25 ( 1 ) , pp.26 - 28

Oxcarbazepine, 10 keto analogue of carbamezepine, is an antiepileptic drug used pri manly for the treatment of focal and generalized tonic clonic seizures in adults and children. Ox carbazepine has been observed to have a positive effect also on psychiatric diseases and trigeminal neuralgia. Oxcarbazepine like most of antiepileptic drugs, inhibits voltage dependent fast sodium channels. During oxcarbazepine treatment, side effects such as hyponatremia, headache, vertigo, somnolence, nausea, double vision, vomiting and ataxia can be seen. However, to date, no specific and!or severe cardiac complications of oxcarbazepine have been rep . . .orted. In this paper, we present a case of complete atrioventricular block that was considered to be caused by oxcarbazepine and that improved after cessation of the drug in a 67 year old female patient with no underlying cardiac etiology.

Aim: P-wave dispersion (PD) has been reported to be associated with inhomogeneous and discontinuous propagation of sinus impulses. Behçet's disease (BD) is a chronic multi-system disease presenting with recurrent oral and genital ulceration, and relapsing uveitis. Left ventricular diastolic dysfunction, ventricular arrhythmia and sudden cardiac death have been documented in Behçet's disease. The aim of this study was to evaluate myocardial involvement noninvasively in patients with BD by measuring PD. Methods: Study population included 29 patients with BD (group I), (16 males, mean age: 60.4 ± 10.1 years), and 45 normal (group II), . . .(23 males, mean age: 61.2 ± 12.0 years). The maximum and minimum P-wave duration (Pmax and Pmin) and PD were measured from the 12-lead surface electrocardiogram. Echocardiographic examination was also performed. Results: There was no statistically significant difference between two groups in respect to age, gender, hypertension, diabetes mellitus, hyperlipidemia and cigarette smoking (p > 0.05). Pmax and PD of patients with BD were found to be significantly higher than those of control subjects (116.2 ± 14.0 ms vs. 102.0 ± 16.5 and 49.3 ± 12.7 ms vs. 29.3 ± 8.5 ms, respectively p < 0.0001). Moreover, we found a significant positive correlation between PD with BD duration (r = 0.78, p < 0.0001). Conclusion: Pmax and PD are found to be greater in patients with BD than in controls and are related with the duration of the disease. © 2007 Elsevier Ireland Ltd.

Behçet's syndrome is a chronic multisystem disease that presents with recurrent oral and genital ulceration and recurrent uveitis. Cardiac involvement is an extremely rare manifestation of this disorder. A 33-year-old man with Behçet's syndrome was admitted to our department with a history of cough, fever, chest pain, hemoptysis, and weight loss. Transthoracic and transesophageal echocardiography revealed a right ventricular thrombus. After 1 month of treatment with warfarin, cyclophosphamide, and corticosteroid, the intracardiac thrombus resolved. © 2007 by the Texas Heart® Institute.

Sayin M.R. | Akpinar I. | Karabag T. | Dogan S.M. | Aydin M.

Article | 2013 | Journal of Cardiology Cases8 ( 1 ) , pp.360 - 362

Dual left anterior descending coronary artery (LAD) is a rare coronary anomaly and is divided into six subgroups in the literature according to the origin and course of the short and long branches of the anomalous artery. We present two distinct cases of dual LAD which are distinguished by two branches of equal length from their counterparts in the literature. Learning objective: In our cases a novel dual LAD variant is presented with two main branches of equal length and reaches the cardiac apex. Cardiologists and cardiovascular surgeons should be aware of these variants to avoid misinterpretation of coronary angiography and intrao . . .perative complications. © 2013 Japanese College of Cardiology Daha fazlası Daha az

Article | 2012 | European Heart Journal Cardiovascular Imaging13 ( 3 ) , pp.251 - 256

Aims: To investigate the atrial electromechanical delay (EMD) duration that is a non-invasive predictor of atrial fibrillation (AF) in patients with Behcet's disease (BD). Methods and results: Thirty-eight Behcet's patients (24 females, 14 males; mean age: 43.6 ± 10.3 years) who were being followed in the dermatology or internal medicine department and 29 demographically matched controls (13 females, 16 males; mean: age 42.6 ± 11.1 years) were included in the study. The inclusion criteria were recurrent oral ulcerations and two of the following features: recurrent genital ulceration, eye lesions, skin lesions or positive pathergy sk . . .in test for Behcet's group. Using tissue Doppler imaging, atrial electromechanical coupling [time interval from the onset of P wave on surface electrocardiogram to the beginning of A wave interval with tissue Doppler echocardiography (PA)] were measured from the lateral mitral annulus (PA lateral), septal mitral annulus (PA septum), and right ventricular tricuspid annulus (PA tricuspid). The mean disease duration was 10.5 ± 7.7 years. The inter-atrial and intra-atrial EMD were significantly higher in the Behcet group than those in the controls (19.8 ± 8.2 vs. 13.1 ± 4.4 ms, P = 0.001; 11.5 ± 7.4 vs. 6.9 ± 3.7 ms, P = 0.02; respectively). The left atrial EMD was similar in both of the groups. However, the P max and PWD values were significantly higher in the BD group compared with those in the controls (120.5 ± 10.1 vs. 112.1 ± 5.9 ms, P < 0.0001; 44.9 ± 10.7 vs. 28.4 ± 5.9 ms, P < 0.0001; respectively). Conclusion: Atrial electromechanical conduction times were increased in the BD patients compared with those in the controls. The tendency of BD patients to go into AF can be easily and non-invasively detected using tissue Doppler echocardiography. These findings may be indicators for subclinical cardiac involvement.

OBJECTIVE: Atrial fibrillation is one of the most common arrhythmias associated with not only increased morbidity after coronary artery bypass grafting but also increased healthcare costs. Many factors are associated with atrial fibrillation onset after coronary artery bypass grafting. We prospectively examined which factors could predict atrial fibrillation after coronary artery bypass grafting. METHODS: Fifty-seven consecutive patients (37 men, mean age=60.2±12 years) with sinus rhythm before coronary artery bypass grafting are included the study. Clinical, demographic, laboratory and echocardiographic characteristics are all eval . . .uated prospectively. The maximum and minimum P-wave duration (Pmax and Pmin) were measured from the 12-lead surface electrocardiogram. The difference between the Pmax and the Pmin was calculated and defined as P-wave dispersion. Preoperative venous blood samples were taken for N-terminal proBrain natriuretic peptide level analysis. RESULTS: Ten (17%) patients had postoperative atrial fibrillation. Patients with postoperative atrial fibrillation were older (69.4±6 versus 58.2±12 years, P=0.01), had lower ejection fraction (44.1±8.9% versus 54.3±9; P=0.002), higher proBrain natriuretic peptide levels (538±136 pg/ml versus 293±359 pg/ml; P=0.03), longer Pmax (142.2±13.7 ms versus 120.8±21.2 ms; P=0.006) and longer P-wave dispersion (55.0±8.2 ms versus 41.3±14.3 ms; P=0.008) compared with the patients without atrial fibrillation. Univariate analysis showed that increased age (P=0.01), lower ejection fraction (P=0.02), enlargement of left atrium (P=0.02), increased Pmax (P=0.006) and increased P-wave dispersion (P=0.008) and increased level of preoperative proBrain natriuretic peptide (P=0.03) were associated with postoperative atrial fibrillation. Positive correlation was seen between the age and level of proBrain natriuretic peptide (r=0.322 and P=0.015). In multivariate analysis, age (P=0.05), lower ejection fraction (P=0.03), left atrial enlargement (P=0.05), longer Pmax (P=0.01) and P-wave dispersion (P=0.01) were found to be independent predictors of postoperative atrial fibrillation. CONCLUSION: Age, poor left ventricular functions, Pmax and P-wave dispersion are found to be independent predictors of atrial fibrillation after coronary artery bypass grafting. © 2007 Lippincott Williams & Wilkins, Inc Daha fazlası Daha az
