Coronary artery fistula: Review of 54 cases from single center experience

Background: Demographic and clinical characteristics and angiographic findings of Turkish patients with coronary artery fistula have been investigated in this study and diagnostic tests and treatment methods used in these patients have also been evaluated in detail. Methods: We have examined the cardiac catheterization laboratory database retrospectively between March 2006 and July 2010. Among 49,567 patients, we have noted 60 patients diagnosed as coronary artery fistula. After coronary angiographic images were evaluated by two invasive cardiologists, 54 patients who had clear evidence of vessel of origin and drainage were included in the study. Results: A total of 54 (0.1%) patients with coronary artery fistula were noted. Mean age was 56.7 ± 10.7 years; 42 out of 54 patients had accompanying cardiac disorders. Patients’ complaints were directly associated with the presence of the fistula. Chest pain was the admission symptom in all of the patients with isolated coronary artery fistula. Six patients had coexistent congenital anomalies. Myocardial infarction with ST segment elevation occurred in 11 of the patients. In contrast to the previous reports, the most common artery of origin of the fistula was left anterior descending artery (50.8%) and pulmonary artery was found to be the most frequent region of the fistula drainage by 53.7%. Conclusions: Our findings suggest that large fistulas originating from the proximal segments of coronary arteries may increase the likelihood of atherosclerosis and myocardial infarction even in asymptomatic patients with no evidence of ischemia in noninvasive tests and no dilatation of cardiac chambers, and should therefore be closed

Radiofrequency Ablation of Typical Atrial Flutter via Right Jugular Vein due to Bilateral Obstructed Iliac Veins in a Patient with Dilated Cardiomyopathy

Ablation of cavotricuspid isthmus (CTI) is the gold standard method in the treatment of isthmus dependent atrial flutter (AFl). Venous access was obtained usually via right or left femoral veins. In rare cases of obstruction of iliofemoral veins, ablation of CTI can be performed only through the superior approach. We present a 74-year-old woman of typical AFl and dilated cardiomyopathy that was ablated through the right jugular vein because of obstruction of the left and the right iliac veins. This is the first report of successful ablation of CTI in a patient with dilated cardiomyopathy via superior approach

The relationship between endothelial nitric oxide synthase 4a/4b gene polymorphism and premature coronary artery disease

Background Nitric oxide (NO) plays a major role in the regulation of endothelial functions and reduced NO synthesis has been implicated in the development of coronary atherosclerosis. Endothelial nitric oxide synthase (eNOS) intron 4a/b polymorphism has been shown to be related to plasma nitric oxide concentrations and coronary artery disease in various population studies. The aim of this study is to assess the relationship between eNOS 4a/b polymorphism and premature CAD

The relationship between coronary artery ectasia and eNOS intron 4a/b gene polymorphisms.

Background Little is known about the pathogenesis and genetics of coronary artery ectasia (CAE). We studied eNOS gene intron 4a/b polymorphism in this patient population

Comparison of Cockcroft-Gault and Modification of Diet in Renal Disease Formulas as Predictors of Cardiovascular Outcomes in Patients With Myocardial Infarction Treated With Primary Percutaneous Coronary Intervention

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 m(2). The eGFRC-G classified 17 patients in the >90 mL/min/1.73 m(2) subgroup and 6 and 11 patients in the 60 to 90 and 90 mL/min/1.73 m(2) (P = .01 and P = .01, respectively); the eGFR(MDRD) 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
