Objective: To report clinical and procedural characteristics of twelve patients who received a covered stent for the treatment of aortic coarctation and concurrent patent ductus arteriosus (PDA).
Methods: A single center database was retrospectively evaluated to obtain data of patients with combined aortic coarctation and PDA. We selected patients in whom a covered stent was used for the treatment of both pathologies. The stent length was chosen so as to cover the entire length of the lesion from healthy to healthy tissue and also cover the ampulla of PDA.
Results: The median age of the patients was 15 (range, 6.5-35) years. The diameter of the coarctated segment increased from a median of 8.4 (range, 2.6-10.8) mm to 16 (range, 9-24) mm (p<0.005), whereas the pressure gradient decreased from a median of 43 (range, 10-71) mm Hg to 0 (range, 0-8) mm Hg (p<0.005). Fourteen covered stents were used for 12 patients. Following deployment, seven stents were flared with larger and low-pressure balloons because of the gap between the distal end of the stent and the poststenotic dilated segment of the aorta, which caused residual PDA shunts and/or instability of the stent. After the procedure, no residual PDA shunt was present in any patient.
Conclusion: To the best of our knowledge, this study includes the largest series of patients reported in literature in whom covered CP stents were used for simultaneous percutaneous treatment of coarctation and PDA. The procedure was successful and stable results were obtained during follow-up in all cases.

Objective: Reversal of myocardial activation sequence during cardiac resynchronization therapy (CRT) may increase the transmural dispersion of repolarization (TDR), which may lead to ventricular arrhythmias. Quadripolar left ventricular (LV) leads offer 10 different pacing configurations. However, little is known about the role of pacing polarity on repolarization patterns. Our study aimed to investigate the impact of LV pacing polarity on depolarization and repolarization parameters in the same substrate in the same patient group.
Methods: This study prospectively analyzed 20 patients who were consecutively admitted and underwent CRT-D implantation with quadripolar LV leads. Two bipolar pacing vectors and two unipolar vectors, also called extended bipolar pacing vectors, from the same pacing sites were selected for comparison. Electrocardiogram markers of depolarization and repolarization were measured and compared.
Results: Bipolar LV pacing was associated with a significantly shorter QRS duration (basal, unipolar vs. bipolar, 135.1±17.8 vs. 119.3±14.5, p<0.01; non-basal, unipolar vs. bipolar, 134.4±15.7 vs. 121.9±10.3, p<0.01) and Tp-Te value (Basal, unipolar vs. bipolar, 119.1±36.7 vs. 97.6±27.9, p<0.05; non-basal, unipolar vs. bipolar, 117.9±36.3 vs. 98.6±20.4, p<0.05) than those in unipolar pacing. LV pacing from basal and non-basal segments had no differential effect on the repolarization parameters.
Conclusion: The LV pacing polarity significantly affects QRS duration but not repolarization patterns regardless of the pacing site in the same substrate. From the perspective of basal and non-basal segments, the LV pacing site has no differential effect on the repolarization parameters.

PMID: 29578203  doi: 10.14744/AnatolJCardiol.2018.59932  Pages 243 - 248
Objective: To share our experience with the left distal radial approach for transradial coronary angiography and interventions. By performing the radial puncture in the fossa radialis or the so called anatomical “Snuffbox” we aimed to present the feasibility and complications of this new technique.
Methods: Left distal radial artery was used as an access site in 54 patients admitted to our clinic for coronary angiography and intervention between May 25th and October 20th 2017. All of them had pulse in their left distal radial artery. In the laboratory, they had their left arm gently flexed at the shoulder so that the hand was placed over their right groin. The operator stood on the right side of the patient and performed coronary angiography and interventions. During the hospital stay, demographic features and complications were recorded.
Results: Mean age of patients was 59.3 years and 80% were male. We used Judkins 6 French catheters for the procedures. Seventeen patients admitted with acute coronary syndrome. They all underwent successful left distal transradial coronary angiography and intervention. Primary angioplasty was performed in 10 patients. In total, 20 patients had coronary intervention. Left anterior descending artery was the artery requiring most intervention (11 patients). Two patients experienced brachial spasm requiring crossover to right femoral artery. There were no cases of radial artery occlusion, hematoma, or hand numbness. The radial sheath was removed at procedure termination. Hemostasis was achieved with manual compression.
Conclusion: Left distal radial approach is safe and feasible as a new technique for coronary angiography and interventions.

PMID: 29615549  doi: 10.14744/AnatolJCardiol.2018.35002  Pages 249 - 258
Objective: The correlation of the BRG1 rs1122608 single nucleotide polymorphism (SNP) with acute myocardial infarction (AMI) has been reported in American and European populations. However, whether rs1122608 acts as a protective factor or a risk factor for AMI is controversial. In this study, we aimed to detect the associations between rs1122608 and the clinical characteristics of AMI as well as susceptibility, gene–environment interactions, and risk factors for AMI in a Chinese Han population.
Methods: In this study, 300 AMI patients and 300 healthy controls of Chinese Han ancestry were enrolled. PCR-RFLP was used to genotype rs1122608 SNPs. Genotypic and allelic frequencies of rs1122608 were compared between the AMI and control groups and among four AMI subgroups, which were subdivided by typical symptom, diagnosis time (DT), infarction location andserious complication.
Results: Significant differences were detected between the AMI patients and the controls in both the genotypic and allelic frequencies of rs1122608 (p<0.001 for each). There were also interactions between the subjects with a minor T allele and smoking or alcohol consumption (p<0.001 for each).
Conclusion: In the Chinese Han study population, the mutant GT and TT genotypes and minor T allele of rs1122608 were positively correlated with the risk of AMI. For the first time, we discovered that the GT genotype of the rs1122608 SNP is significantly correlated with diagnosis time of AMI. In addition, the interactions between the minor T allele of rs1122608 and smoking or alcohol use and between the rs1122608 CC genotype and alcohol use appear to increase the risk of AMI.

PMID: 29615543  doi: 10.14744/AnatolJCardiol.2018.00236  Pages 259 - 266
Objective: Depressed mechanical activity is a marked complication in diabetics. Hypoxia has properties for novel diagnostic and therapeutic strategies, while intermittent hypoxia (IH) provides early functional and histologic remodeling, including some cardio benefits in early hemodynamic alterations with histologic remodeling and delayed changes in peripheral vasoreactivity. Therefore, we aimed to examine whether IH application presents a cardioprotective effect, via stabilization of hypoxia-inducible factor (HIF) in streptozotocin (STZ)-induced diabetic rat heart.
Methods: Male 10-week-old Wistar rats were randomly assigned as control group (C), IH group, (STZ)-induced diabetic group (DM) and IH applied DM group (DM+IH). Diabetes duration was kept 6 weeks and IH groups were exposed to hypobaric hypoxia at about 70 kPa (including ~14% PO2; 6 h/day for 6-weeks).
Results: Depressed left ventricular developed pressure (LVDP) and prolonged contraction and relaxation of Langendorff-perfused hearts, as well as increased total oxidative status from streptozotocin (STZ)-induced diabetic rats were markedly prevented with IH application. IH application induced significant increase in protein expression levels of both HIF-1α and vascular endothelial growth factor (VEGF), in both control and diabetic rat hearts, whereas there were significant decreases in the protein levels of prolyl-4 hydroxylase domain enzymes, PHD2, and PHD3 in diabetic hearts. Furthermore, IH application induced marked increases in protein levels of matrix metalloproteinases, MMP-2 and MMP-9 and capillary density in left ventricle of diabetic rats.
Conclusion: Overall, we presented how IH application has a beneficial cardiovascular remodeling effect in left ventricular function of diabetic rats, at most, via affecting increased oxidative stress and HIF-VEGF related angiogenesis, providing information on hyperglycemia associated new targets and therapeutic strategies.

Özge Turgay Yıldırım, Aylin Yıldırır, Leyla Elif Sade, Senem Has Hasırcı, Hatice Kozan, Emre Özçalık, Kaan Okyay, Uğur Abbas Bal, Alp Aydınalp, Haldun Müderrisoğlu
PMID: 29615544  doi: 10.14744/AnatolJCardiol.2018.66181  Pages 267 - 272
Objective: Resistin, a cysteine-rich peptide, is associated with atherosclerosis and diabetes. Resistin levels increase corresponding to coronary artery disease (CAD) and heart failure severity. Since resistin level tends to elevate with symptomatic heart failure, it is expected to be associated with left ventricular end-diastolic pressure (LVEDP). However, there is no relevant literature on the relationship between resistin levels and LVEDP. We aimed to evaluate the association between resistin levels and LVEDP, severity of CAD, carotid intima-media thickness (CIMT), and echocardiographic diastolic dysfunction parameters.
Methods: For this study, 128 euvolemic patients with creatinine clearance >50 mg/dL and without acute coronary syndrome, who had typical chest pain or were stress test positive, were enrolled. Resistin level was measured by Enzyme-linked immunosorbent assays (ELISA) method. Severe CAD is defined as ≥50% stenosis in one of the major coronary arteries. LVEDP was measured during left heart catheterization.
Results: After coronary angiography, 60 patients (46.9%) had severe CAD. The mean LVEDPs were similar for patients with and without severe CAD (p=0.480). The resistin levels did not differ between the groups (p=0.154). The resistin levels did not correlate with LVEDP (r=−0.045, p=0.627), ejection fraction (EF; r=0.110, p=0.228), the Gensini score (r=−0.091, p=0.328), and CIMT (r=0.082, p=0.457). No significant correlation was found between the echocardiographic diastolic dysfunction parameters and resistin levels.
Conclusion: There was no significant correlation between resistin level and LVEDP, CAD severity, echocardiographic diastolic dysfunction parameters, and CIMT. Further studies are warranted to determine the efficacy of resistin in clinical use.

PMID: 29615545  doi: 10.14744/AnatolJCardiol.2018.37929  Pages 273 - 278
Objective: Chronic thromboembolic disease (CTED) is characterized by persistent pulmonary thromboembolic occlusions without pulmonary hypertension. Early surgical treatment by performing pulmonary endarterectomy (PEA) may improve symptoms. The goal of the study was to review our experience and early outcome of PEA in patients with CTED.
Methods: Data were prospectively collected on all patients who underwent PEA between 2011 and 2015. Patients with CTED and a mean pulmonary artery pressure (mPAP) of <25 mm Hg were identified. All patients were in New York Heart Association (NYHA) functional class II or III. Measured outcomes were in-hospital complications, improvement in cardiac function and exercise capacity, and survival after PEA. Patients were reassessed at 6 months following surgery.
Results: A total of 23 patients underwent surgery. There was no in-hospital mortality, but complications occurred in six patients (26%). At 6 months following surgery, 93% of the patients remained alive. Following PEA, the mPAP fell significantly from 21.0±2.7 mm Hg to 18.2±5.5 mm Hg (p<.001). Pulmonary vascular resistance also significantly decreased from 2.2±0.7 wood to 1.5±0.5 wood (p<.001). The 6-min walking distance significantly increased from 322.6±80.4 m to 379.9±68.2 m (p<.001). There was a significant symptomatic improvement in all survivors in NYHA functional classes I or II at 6 months following surgery (p=.001).
Conclusion: PEA in selected patients with CTED resulted in significant improvement in symptoms. The selection of patients for undergoing PEA in the absence of pulmonary hypertension must be made based on patients’ expectations and their acceptance of the perioperative risk.

Myocarditis is an inflammatory disease of the myocardium with a broad spectrum of clinical presentations, ranging from mild symptoms to severe heart failure. The course of patients with myocarditis is heterogeneous, varying from partial or full clinical recovery in few days to advanced low cardiac output syndrome requiring mechanical circulatory support or heart transplantation. Fulminant myocarditis (FM) is a peculiar clinical condition and is an acute form of myocarditis, whose main characteristic is a rapidly progressive clinical course with the need for hemodynamic support. Despite the common medical belief of the past decades, recent comprehensive data, including a recent registry that compared FM with acute non-FM, highlighted that FM has a poor inhospital outcome, often requires advanced hemodynamic support, and may result in residual left ventricular dysfunction in survivors. This review aimed to provide an updated practical definition of FM, including essentials in the diagnosis and management of the disease. Finally, the outcome of FM was critically revised according to the current published registries focusing on the topic.
