The surgical treatment of diffuse thoracic aortic pathologies remains a challenge in aortic surgery for surgeons. Traditionally, these aortic diseases are treated with a 2-step approach known as the "elephant trunk procedure." This technique gives us an opportunity for the construction of the distal anastomosis during the initial operation. However, this staged approach is associated with a substantial overall mortality and morbidity. In order to improve the outcomes, few single-stage repair methods have been tried. Most of them are performed through a clamshell incision, and for this reason, it is potentially associated with a high incidence of pulmonary complications. Repair techniques of diffuse thoracic aortic pathologies have changed substantially over the last decade; these techniques appear to have a significant lower operative risk for patients. "Frozen elephant trunk" (FET) technique was developed for combined lesions of the thoracic aorta as a single-stage procedure which is a combination of endovascular treatment and conventional surgery. However, experiences are limited in the field of FET and endovascular techniques that is why traditional 2-staged approach still remains as a first choice in our clinic like many centers. In eligible patients, we use a handmade skirted tube graft for conventional technique in 2-staged repair for diffuse thoracic aortic aneurysm. In this report, we aim to explain the possible advantages of this graft and how we do it. © 2017 Elsevier Inc.

Sugammadex encapsulates and inactivates rocuronium and vecuronium. It is used to reverse neuromuscular blockade from these nondepolarizing agents. The safety of sugammadex in patients with neuromuscular disease has not been established. Guillain-Barre Syndrome (GBS) is a neuromuscular disease characterized by acute inflammatory polyneuropathy. Patients with GBS may exhibit autonomic dysfunction, chronic pain, abnormal reactions to neuromuscular blocking agents, and may require postoperative mechanical ventilation. We report the successful use of sugammadex to reverse rocuronium in a patient with chronic GBS, who presented for a hemicolectomy.

Aim: We aimed to investigate the relationships between metabolic syndrome (MS) and monocyte to high density lipoprotein cholesterol ratio (MHR) and lymphocyte-to-monocyte ratio (LMR). Methods: 762 patients (n = 371 MS present and n = 391 MS absent) were enrolled. Results: MHR was significantly higher [13.9 (10.5-18.1) vs 11.1 (8.0-14.8); p < 0.001], whereas LMR was significantly lower [4.5 (3.6-5.7) vs 3.6 (2.9-4.8); p < 0.001] in patients with MS. LMR [OR: 0.796 (95% CI): 0.711-0.892); p < 0.001], MHR [OR: 1.052 (95% CI: 1.018-1.088); p = 0.003] and C-reactive protein [OR: 1.048 (95% CI: 1.032-1.065); p < 0.001] remained as independent variables for the presence of MS. Conclusion: The present study shows that both LMR and MHR may be novel and useful indicators of MS. © 2017 Future Medicine Ltd.

BackgroundThis pilot study aimed to evaluate the effectiveness of posterior left atrial wall plication (T-plasty) in patients with persistent atrial fibrillation (AF) (> 7 days) undergoing mitral valve surgery. Materials and MethodsA total of 60 patients who were scheduled for mitral valve replacement were randomly allocated into two groups: one would receive (Group 1; n=32, mean age; 49.379.00) and one would not receive (Group 2; n=28; mean age 48.648.6) left atrial size reduction using T-plasty technique. Patients with a clear indication for combined procedures other than tricuspid valve disease, aortic valve disease, and coronary artery stenosis were not included. Follow-up was performed at 6th, 12th, and 18th months after the operation. ResultsAfter the operation, 21 patients (65.6%) in Group 1 and 13 patients (46.4%) in Group 2 regained sinus rhythm (p=0.13). Mortality did not occur. AF recurrence rates were not significantly different between the groups in three follow-ups. Restoration of sinus rhythm was significantly more common in Group 1 patients than in Group 2 patients during follow-up. Patients in Group 1 had lower left atrial volume indexes than those in Group 2 at the 6th and 12th months, whereas the difference at the 18th month was at the limit of significance. ConclusionWe achieved satisfactory results using the T-plasty technique for left atrial size reduction in terms of mid-term restoration and preservation of normal sinus rhythm in patients undergoing mitral valve surgery. Further study may be justified to reveal the prognostic importance of the technique described herein.

Patients with diabetes have an increased risk for development of cardiomyopathy, even in the absence of well known risk factors like coronary artery disease and hypertension. Diabetic cardiomyopathy was first recognized approximately four decades ago. To date, several pathophysiological mechanisms thought to be responsible for this new entity have also been recognized. In the presence of hyperglycemia, non-enzymatic glycosylation of several proteins, reactive oxygen species formation, and fibrosis lead to impairment of cardiac contractile functions. Impaired calcium handling, increased fatty acid oxidation, and increased neurohormonal activation also contribute to this process. Demonstration of left ventricular hypertrophy, early diastolic and late systolic dysfunction by sensitive techniques, help us to diagnose diabetic cardiomyopathy. Traditional treatment of heart failure is beneficial in diabetic cardiomyopathy, but specific strategies for prevention or treatment of cardiac dysfunction in diabetic patients has not been clarified yet. In this review we will discuss clinical and experimental studies focused on pathophysiology of diabetic cardiomyopathy, and summarize diagnostic and therapeutic approaches developed towards this entity. © 2015 The Korean Society of Cardiology.

Endothelial dysfunction plays a major role in erectile dysfunction (ED). Atrial fibrillation (AF), regardless of subtype, is associated with a prothrombotic state, which is related to endothelial dysfunction. In this study, we aimed to determine whether AF is an independent risk factor for ED.A total of 50 patients diagnosed with paroxysmal lone AF and 80 age-, gender-, and body mass index-matched controls without AF who admitted to outpatient clinics at a tertiary center were enrolled. Diagnosis of ED was performed by using Sexual Health Inventory for Men (SHIM) questionnaire. Patients with a SHIM score 21 were defined as having ED.Mean age of patients were 51.87.7 and all of the study population were male. Twenty-nine of 50 patients in lone AF group and 25 of 80 patients in control group were diagnosed with ED (58 vs 31.2%, p=0.002). Mean SHIM score was significantly lower in lone AF group compared with controls (20.742.67 vs 22.392.21, p<0.001). The multivariate stepwise logistic regression analyses showed that lone AF (OR 1.94 (1.44-2.46), p<0.001), smoking (OR 1.92 (1.35-2.44), p=0.003), fasting blood glucose (OR 1.51 (1.10-1.85), p=0.012), and uric acid levels (OR 1.56 (1.13-1.92), p=0.009) were independent predictors of ED.Beat-to-beat variation may lead to ED in patients with paroxysmal lone AF and questioning erectile function in patients with lone AF may be recommended.

We investigated the relationship between resting heart rate (HR) and The Synergy between percutaneous coronary intervention with Taxus and cardiac surgery (SYNTAX) score in patients with stable coronary artery disease (SCAD). A total of 420 patients who were admitted to our outpatient clinic for stable angina pectoris with sinus rhythm and had at least 50% narrowing in at least 1 coronary artery after coronary angiography were included in the study. Patients were divided into 3 tertiles based on the resting HR: HR of tertile 1 was 65 (n = 138), tertile 2 was between 66 and 76 (n = 139), and tertile 3 was 77 beats/min (n = 143). The SYNTAX score (7.6 4.6, 12.4 5.6, 20.3 8.1; P < .001) was significantly higher for those in tertile 3 than for those in tertiles 1 and 2. Leukocyte count (7.8 2.2, 7.9 2.2, 8.4 2.3 10

OBJECTIVE: The CHA2DS2-VASc score is used to estimate thromboembolic risk in atrial fibrillation (AF). Its usefulness in predicting outcome in patients after a percutaneous coronary intervention is unknown. We aimed to evaluate the predictive value of the CHA2DS2-VASc score in AF-free patients who have undergone stent implantation. DESIGN: Patients were evaluated retrospectively. Among the 1371 patients, 38 presented with acute stent thrombosis (ST) and were included in the study. The CHA2DS2-VASc score was calculated before percutaneous coronary intervention and the association between the score and stent thrombosis was investigated. RESULTS: The patients were grouped into ST (+) and ST (−). The average CHA2DS2-VASc score for the ST (+) group was 3.79, whereas that for the ST (–) group was 2.16 (P<0.001). A direct correlation was observed between CHA2DS2-VASc scores and the rate of ST. When patients with a CHA2DS2-VASc score of greater than 2 were compared with those with a CHA2DS2-VASc score of up to 2, the higher score had a higher frequency of ST (P<0.001) and multivariate analysis identified the CHA2DS2-VASc score as an independent predictor of acute ST. CONCLUSION: A CHA2DS2-VASc score of greater than 2 was found to be an independent predictor for incidence of ST. The role of the CHA2DS2-VASc score in predicting ST has not been investigated earlier in an AF-free population and our study is the first to explore this aspect.

We investigated the relationship between epicardial adipose tissue (EAT) and infarct-related artery (IRA) patency before mechanical reperfusion in patients with ST-segment elevation myocardial infarction (STEMI). Patients (n = 640) were divided into 2 groups based on the thrombolysis in myocardial infarction (TIMI) flow grade. Impaired flow was defined as TIMI grades 0, 1, and 2, and normal flow was defined as TIMI 3. On the admission angiography, 65 (10.2%) patients had TIMI 3 flow, and the remaining 575 (89.8%) had TIMI 0, 1, or 2 flow. The impaired flow group patients had a higher incidence of diabetes mellitus (53.7% vs 41.5%, P = .035), higher EAT thickness (5.66 1.84 vs 4.87 2.09 mm, P = .001), and lower ejection fraction (43.1% 8.9% vs 47.4% 9.1%, P = .025). Multivariate stepwise logistic regression analysis showed that IRA patency was independently associated with EAT thickness (odds ratio [OR] 0.785; 95% confidence interval [CI] 0.712-0.858; P = .001) and neutrophil-lymphocyte ratio (OR 0.815; 95% CI 0.732-0.917; P = .025). Thickness of EAT was an independent predictor of lower TIMI flow in IRA in patients with STEMI.
