RESUMO
BACKGROUND: This study aims to present our experiences on endovascular and hybrid treatment of peripheral arterial diseases. METHODS: Between March 2008 and April 2016, 86 patients who underwent endovascular treatment and 17 patients who underwent hybrid treatment for peripheral arterial disease in our clinic were retrospectively analyzed. The treatment approaches, success of treatments, complications and outcomes of these patients were studied. RESULTS: No mortality was seen during the procedures. Following the procedure, the patients were hospitalized in the intensive care unit under standard heparin treatment for six hours at least. Anticoagulation was maintained with low-molecular-weighted heparin for three days, followed by dual oral antiaggregant (acetylsalicylic acid 100 mg + clopidogrel 75 mg). Repeated Doppler ultrasonography revealed no in-stent thrombosis or restenosis at the site of ballooning during hospitalization. None of the patients with normal renal functions preoperatively experienced severe renal failure. Although nearly all femorodistal interventions were performed in the antegrade way, none of the patients had bleeding complications at the site of intervention. All patients were discharged within 1 to 16 days. CONCLUSION: Endovascular and hybrid modalities are safe and comfortable in the treatment of peripheral arterial diseases for vascular surgeons having a hybrid room.
RESUMO
Cor triatriatum sinister (CTS) is a rare congenital abnormality. Clinical presentation of patients with CTS mainly depends on the anatomic features of membrane and may vary from mild or moderate symptoms mimicking mitral stenosis to more severe and complicated cardioembolic stroke or a new onset heart failure. We herein have reported on a young male who presented with the signs and symptoms of mitral stenosis and was diagnosed as CTS with gradient on the orifice of the membrane after transthrocacic echocardiography. Computerized tomographic angiography revealed that the patient had unilateral, left sided pulmonary arterial hypoplasia and pulmonary vein atresia, with only the right pulmonary veins draining into the left atrial chamber. Further cardiac imaging by either computed tomography or magnetic resonance imaging is necessary in order to seek accompanying cardiac and vascular abnormalities. Patients with CTS have improved short and long term survival rates if CTS and accompanying abnormalities are surgically treated before the disease is complicated with heart failure, pulmonary hypertension, stroke and etc.

AIM: Sympathetic overdrive is generally the main pathophysiological abnormality in cardiovascular disease. However, its grading is not easy in clinical practice because of its complex interactions and differences in phenotypical expression. We proposed an easy, feasible, and global scaling system for sympathetic activity level. 'Sympathetic activity index' (SAI) is based on scores of heart rate, BMI, and blood pressure categories, which are the major representatives of sympathetic activity. MATERIALS AND METHODS: Respectively, 1, 2, and 3 points were determined for heart rate below 69, 70-89, and above 90 bpm; -1, 1, and 2 points for BMI less than 20, 20-24.9, and at least 25 kg/m; and 1, 2, and 3 points for normal, prehypertension, and hypertension categories. Demographic and echocardiographic parameters, and left ventricular (LV) mass and mass indexes (LVMIBSA and LVMIHeight) of 545 young males were compared among groups with SAI 1-8. RESULTS: We observed that LVM, LVMIBSA, and LVMIHeight, left atrial diameter were significantly increased in association with SAI (P<0.001). SAI was correlated with LVM (R=0.314, P<0.001), LVMIBSA (R=193, P<0.001), and LVMIHeight (R=0.316, P<0.001). SAI of at least 5.5 could determine the left ventricular hypertrophy with a sensitivity and a specificity of 57 and 70%, respectively (AUC=682, 95% confidence interval 0.610-0.753, P<0.001). CONCLUSION: Integration of clinical, anthropometric, and hemodynamic variables in a novel index such as SAI may provide an objective and noninvasive means of grading actual sympathetic drive. SAI may be used to follow-up sympathetic activity and to predict clinical events in the management of young patients with cardiovascular and metabolic abnormalities.

PURPOSE: Our aim was to determine whether there is a correlation between cross-sectional areas of the left main coronary artery (LMCA), left anterior descending artery (LAD), and circumflex artery (CX) in normal cases using coronary CT angiography. METHOD: Examinations of 180 patients (119 men and 61 women) were selected among 2248 consecutive coronary CT angiography studies. Cross-sectional areas of LMCA, LAD, and CX were measured at the level of bifurcation. Correlation between age, height, and body mass index and coronary artery cross-sectional areas was investigated and possibility of formulating a correlation between the cross-sectional areas of LMCA, LAD, and CX was explored. RESULTS: Mean cross-sectional areas of LMCA, LAD, and CX were found as 17.4±3.9 mm2, 12.5±3.1 mm2, and 10.5±3.0 mm2, respectively. While cross-sectional areas of LMCA and LAD were significantly larger in men, no significant difference was found between the sectional areas of CX in men and women. A multiple regression analysis was conducted to elucidate the relationship between the cross-sectional areas of LMCA LAD, and CX. Our analysis showed that the relationship between LMCA, LAD, and CX cross-sectional areas can be formulated as follows: LMCA=3.870 + 0.718×LAD + 0.434×CX. CONCLUSION: There is a correlation between the cross-sectional areas of LMCA, LAD, and CX at the level of bifurcation, and this correlation can be expressed with a formula.

OBJECTIVE: Neutrophil-lymphocyte ratio (NLR) has been associated with poor outcomes in patients with cardiovascular diseases. We aimed to compare NLRs among patients with nonvalvular atrial fibrillation (AF) with or without left atrial (LA) thrombus. METHODS: A total of 309 (70.1 ± 9.8 years, 49% male) patients with nonvalvular AF have undergone transoesophageal echocardiography (TEE) to assess the presence of LA thrombus. Baseline NLR was measured by dividing neutrophil count to lymphocyte count. RESULTS: Left atrial thrombus was detected in 32 (10.3%) of 309 patients. Mean NLR (2.2 ± 1.0 vs 2.7 ± 1.1, P = .026) was significantly higher among patients with LA thrombus compared to patients without LA thrombus. On multivariate analysis, NLR (odds ratio 1.59, 95% confidence interval 0.87-4.18; P < .02) was an independent risk factor for the presence of LA thrombus in patients with nonvalvular AF. CONCLUSION: Neutrophil-lymphocyte ratio, an emerging marker of inflammation, was independently associated with the presence of LA thrombus in patients with nonvalvular AF.

OBJECTIVES: Carbon monoxide (CO) poisoning leads to cardiac dysrhythmia. Increased heterogeneity in ventricular repolarisation on electrocardiogram (ECG) shows an increased risk of arrhythmia. A number of parameters are used to evaluate ventricular repolarisation heterogeneity on ECG. The aim of our study is to investigate the effect of acute CO poisoning on indirect parameters of ventricular repolarisation on ECG. METHODS: Sixty-seven patients were included in this case-control study. Thirty patients with acute CO poisoning were assigned to group 1 (19 females, mean age: 30.8 ± 11.3 years). A control group was formed with patients without known cardiac disease (group 2, n = 37; 25 females, mean age: 26.0 ± 5.2 years). Twelve-lead ECG and serum electrolyte levels were recorded in all patients. Also, carboxyhaemoglobin (COHb) levels were recorded in group 1. Tpeak-Tend (TpTe) interval, TpTe dispersion, TpTe/QT ratio, QT interval and QTd durations were measured as parameters of ventricular repolarisation. Corrected QT (QTc ) and QTc dispersion (QTcd) intervals were determined with the Bazett's formula. RESULTS: The mean COHb level in group 1 was 27.6 ± 7.4% and mean duration of CO exposure was 163.5 ± 110.9 min. No statistically significant difference was found in age, gender, serum electrolytes or blood pressure levels between the groups. QRS, QT, QTc, TpTe interval and TpTe/QT ratio were similar between the groups (p > 0.05). QTcd (65.7 ± 64.4 vs 42.1 ± 14.2 ms, p = 0.003) and TpTe dispersion (40.5 ± 14.8 vs 33.2 ± 4.9 ms, p = 0.006) were significantly longer in group 1 than group 2. COHb level was moderately correlated with TpTe dispersion (r = 0.29; p = 0.01). CONCLUSION: To our knowledge, this is the first study to investigate TpTe interval and dispersion in CO poisoning. Our results showed that TpTe dispersion and QTc dispersion increased after CO poisoning.

OBJECTIVE: To investigate whether or not the CHA2DS2-VASc score predicts left atrial (LA) thrombus detected on pre-cardioversion transoesophageal echocardiography (TEE). MATERIALS AND METHODS: The medical records of patients who had undergone TEE were reviewed to assess the presence of LA thrombus prior to direct-current cardioversion for atrial fibrillation (AF). The CHA2DS2-VASc score was calculated for each patient. Clinical TEE reports were reviewed for the presence of LA thrombus. Patients with a valve prosthesis or rheumatic mitral valve disease were excluded from this study. RESULTS: A total of 309 patients were identified. The mean age was 70.1 ± 9.8 years and 151 (49%) patients were males and 158 (51%) were females. LA thrombus was seen in 32 (10.3%) of the 309 patients. Fifty (16.2%) patients had a low CHA2DS2-VASc score (0-1), 230 (74.4%) had an intermediate score (2-4) and 29 (9.4%) had a high score (5-9). The incidence of LA thrombus in the low, intermediate and high CHA2DS2-VASc score groups was 0, 4.4 and 68.7%, respectively. The LA thrombus risk increased with increasing CHA2DS2-VASc scores. On multivariate logistic analysis, the CHA2DS2-VASc score (OR 3.26, 95% CI 2.3-4.65; p = 0.001) and age (OR 0.93, 95% CI 0.88-0.98; p = 0.004) were independent risk factors for LA thrombus in patients with non-valvular AF. CONCLUSION: A high CHA2DS2-VASc score was independently associated with the presence of LA thrombus in patients with non-valvular AF.
