Objectives: We evaluated the relationship between serum gamma-glutamyltransferase (GGT) levels and the burden of atherosclerosis in patients with acute coronary syndrome (ACS).
Study design: This study involved 180 patients (139 male, 41 female; mean age 63±11 years) with the diagnosis of ACS (non- ST elevation myocardial infarction and unstable angina) who underwent coronary angiography on the first day after hospital admission. The burden of atherosclerosis was assessed by the number of involved vessels, and the Gensini and Syntax scores. Serum GGT levels were measured by enzymatic caloric test.
Results: Patients with high Syntax scores (≥33) were more frequently diabetic, hypertensive, and had higher GGT and creatinine levels compared to the patients with low Syntax scores (≤23). Similarly, patients with ≥3 diseased vessels were more frequently diabetic, hypertensive, and smokers. In addition, these patients were older and had higher serum glucose, urea and GGT levels. Correlation analysis revealed that the level of GGT was significantly associated with Gensini and Syntax scores, number of diseased vessels, and the number of critical lesions (r=0.378 p<0.001, r=0.301 p<0.001, r=0.159 p=0.036, r=0.355 p<0.001, respectively). Multivariate linear regression analysis demonstrated that increased GGT level was an independent risk factor for high Gensini and Syntax scores (p=0.029 and p=0.035, respectively), together with age (p=0.001 and p=0.002, respectively) and serum glucose levels (p=0.017 and p=0.012, respectively).
Conclusion: Serum GGT levels on admission are associated with increased burden of atherosclerosis in patients with ACS. This may account for the cardiovascular outcomes associated with increased GGT levels.

Objectives: It is well known that inflammation plays a key role in both initiation and propagation of acute coronary syndrome (ACS). White blood cell (WBC) and its subtypes are an indicator of inflammation in patients with ACS. We aimed to evaluate the WBC and its subtypes in patients aged <45 year with acute coronary syndromes.
Study design: We retrospectively analyzed WBC and its subtypes (including neutrophil and lymphocyte) in 84 patients (<45 year) who were admitted to the emergency department for chest pain suggestive of ACS (44 unstable angina pectoris, 40 non-ST-segment elevation myocardial infarction [NSTEMI]), and 40 healthy controls.
Results: Hypertension, diabetes mellitus, smoking, and family history were significantly higher in NSTE-ACS patients. Also, LDL levels was significantly higher and HDL levels was significantly lower in NSTE-ACS patients (p=0.041 and p=0.009). The difference in percent of lymphocytes between the groups was significant (p=0.048). N/L ratio was significantly different between all groups and between the NSTEMI and USAP (p<0.001 and p=0.041). Our results demonstrated that hypertension, percent of neutrophils, and N/L ratio was a significant independent predictor of NSTE-ACS (Beta=0.251, 95% CI=0.002-0.523, p=0.048; beta=0.561, 95% CI=0.008-0.137, p=0.028 and beta=0.260, 95% CI=0.042-0.438, p=0.018, respectively).
Conclusion: N/L was found to be elevated in young patients with NSTE-ACS compared with control group. The inflammation assessed using WBC and its subtypes may be more important in young NSTE-ACS patients.

Objectives: Cardiac syndrome X (CSX) is a clinical entity that is defined as normal coronary arteries with angina pectoris and objective sins of ischemia. The correlation between CSX and inflammatory markers such as high-sensitivity C-reactive protein (hs-CRP) is well established, however an association with pentraxin- 3 (PTX-3) has not been examined. The aim of this study was to investigate the association between PTX-3 and CSX.
Study design: A total of 122 patients (58 female, 64 male, mean age 49.6±5.8 years) with suspected of coronary artery disease (CAD) were included in the study. Those with evidence of ischemia (50 patients with positive treadmill tests, 32 patients with positive myocardial perfusion scintography) underwent coronary angiography (82 patients). Patients with a normal angiogram were considered the CSX group (n=41) and patients with coronary lesions were referred to as the CAD group (n=41). Patients without signs of ischemia served as the control group. Serum PTX-3 and hs-CRP levels were measured in all patients.
Results: The CSX group had significantly increased PTX-3 levels relative to the control group (0.46±0.16 vs. 0.23±0.09 ng/ml, p<0.001). However there were no differences in levels of PTX-3 and hs-CRP between the CSX and the CAD groups (PTX-3: 0.46±0.16 vs. 0.51±0.13 ng/ml, p=0.21; hs- CRP: 1.04±0.45 vs. 1.16±0.64 mg/dl, p=0.62). The control group had significantly lower hs-CRP levels (0.73±0.51 mg/ dl) when compared to the both CSX and CAD groups (p=0.03 and p=0.002, respectively). Serum PTX-3 levels were weakly correlated with hs-CRP levels (r=0.30, p=0.001).
Conclusion: PTX-3, a novel inflammatory marker, is elevated in patients with CSX, similar to the well known inflammatory marker hs-CRP, and may be a promising biomarker reflecting inflammatory status in these patients.

Objectives: Pulmonary vein (PV) isolation with cryothermal energy is a recently introduced technique in patients with atrial fibrillation (AF). It may reduce procedural times and serious complications associated with radiofrequency (RF) ablation. We aimed to present the baseline characteristics and followup data of our study population undergoing cryoballoon AF ablation.
Study design: A total of 236 patients (126 male, 110 female; mean age 54.6±10.45; range 16 to 78 years) underwent PV isolation with 28 mm cryoballoon due to symptomatic AF. These patients failed with at least one previous antiarrhythmic drug. The postprocedure in the first 3 months was defined as blanking period. Median follow-up time was 14 (3-24) months. Procedural success, complicaitons, and follow-up results were defined according to Heart Rhythm Society guidelines.
Results: Acute procedural success rate (≥3 PV isolation) was 99.5%. Mean procedural and fluoroscopy times were 72.5±5.3 (50-90) min and 14±3.5 (12-24) min. Major complications were observed in 3 patients (1.2%). At the median 14 month follow-up, 80.6% of paroxysmal AF patients and 49.2% of persistant AF patients were free from AF recurrence. RF ablation was performed in 10 patients with recurrence. Smoking, body mass index, non-paroxysmal AF type, AF duration (years), left atrial size, and early recurrence were the predictors of recurrence in multivariate regression analysis.
Conclusion: This study represents the first experience with cryoballoon ablation for AF in Turkey. The efficacy and safety of cryoballoon AF ablation technique was shown due to the acceptable success and low complication rates in paroxysmal AF patients. Particularly, patients with early recurrence should be closely followed-up.

Objectives: To evaluate short term results of percutaneous patent ductus arteriosus (PDA) closure in a cohort of pediatric and adult patients following closure with the Amplatzer Ductal Occluder (ADO-1 and ADO-2) and Amplatzer Septal Occluder (ASO) devices.
Study design: A total of 48 patients (17 male and 31 female; range 3 to 39 years) were included in this study. All patients were evaluated with transthoracic echocardiography (TTE) before intervention. Percutaneous closure was performed under fluoroscopy through anterograde or retrograde route. Aortagraphy was performed to measure and classify the ductus arteriosus. Residual shunt through ductus was controlled by aortography at the tenth minute and by TTE 24 hours and three months after the procedure.
Results: The released device was ADO-1 in 25 patients (51.2%), ADO-2 in 22 patients (45.8%), and ASO in one patient. Mean follow-up was 13.2 months. In 97.9% of patients, the occluder was placed into the ductus without any complication. In one patient, the device embolized to the left pulmonary artery during implantation. Aortography performed ten minutes after the procedure showed complete closure in 38 patients without residual defect. TTE revealed trace amounts of residual shunt within the device in two patients, flow around the device in two patients 24 hours after implantation, and residual shunt in only one patient three month after intervention.
Conclusion: Transcatheter closure of PDA with ADO-1 and ADO-2 devices has low morbidity and mortality with high rates of success in selected patients.

Objectives: We aimed to compare the efficacy of primary percutaneous coronary intervention (p-PCI) in patients ≥80 versus <80 years of age with ST-segment elevation myocardial infarction (STEMI).
Study design: We retrospectively enrolled 2213 patients with acute STEMI. The patients were prospectively followed up for a median of 42 months. Early and late clinical outcomes were compared according to age.
Results: One-hundred and seventy-nine (8.1%) of the 2213 patients were aged ≥80 years. Post-procedural TIMI grade 3 flow was significantly less frequent in the age ≥80 years patients (82.1% vs. 91.1%, p<0.001). Rates of mortality (14.5% vs. 3.4%, p<0.001), heart failure (20.7% vs. 10.5%, p<0.001), major hemorrhage (9.5% vs. 3.3%, p<0.001), secondary VT/VF (10.1% vs. 4.2%, p=0.002) and atrial fibrillation (12.8% vs. 4.3%, p<0.001) during the early hospitalization period were significantly higher in the age ≥80 years patient group. Overall rates of mortality (40% vs. 9.7%, p<0.001) and total stroke (5.6% vs. 1.1%, p=0.005) at long-term follow-up were also higher in the age ≥80 years patient group. However, there was no difference between the two groups with respect to the reinfarction/revascularization rates. Analysis, using the Cox proportional hazards model, revealed that age ≥80 to was an independent predictor of longterm mortality (hazard ratio 2.17, 95% CI 1.23-4.17, p=0.02).
Conclusion: Age is an independent predictor of mortality after p-PCI for STEMI. Although it seems to improve early outcomes, the efficacy of p-PCI at long-term follow-up is limited in elderly patients.

A 73-year-old female patient underwent transradial coronary angiography with stable angina and signs of significant myocardial ischemia revealed by exercise stress test. After insertion of a 6F radial sheath into the right radial artery and intra-arterial administration of heparin plus verapamil, the hydrophilic guidewire could not be advanced under fluoroscopic guidance. Immediately afterwards, radial angiography was performed, which displayed a radial artery perforation with significant contrast extravasation. The perforated segment was crossed meticulously with the same guidewire after additional vasodilator drug administration. Afterwards, a 5F TIG catheter was advanced to the axillary artery and held in place for 20 minutes with application of external compression with a sphygmomanometer cuff at the level of systolic blood pressure. The same maneuver was again performed following cuff deflation and completion of coronary angiography with the 5F catheter. Final angiography displayed complete sealing of the perforation without a need for neutralization of heparin. External compression was continued for two hours, and after documentation of normal triphasic radial artery flow by Doppler ultrasound (DUS), the radial sheath was removed. The patient was discharged the following day with no evidence of hand ischemia and wellpalpable radial artery pulse. DUS demonstrated normal radial artery flow one month later. This unusual complication was managed successfully with a simple and easily applicable technique that can be performed in such cases.

In this article, we present a case with isolated right ventricular myocardial infarction (MI) who underwent coronary angiography on suspicion of acute anteroseptal MI detected on ECG; however, occlusion of the proximal right coronary artery (RCA) was detected. A female patient aged 65 years was brought to the emergency room due to loss of consciousness 1 hour before. From the patient’s history, it was understood that she had undergone stent placement to her proximal RCA 5 days before. On ECG, a decreasing elevation in ST segment elevation from V1 to V4 was seen, and pathologic Q waves were present at DIII and AVF. A complete AV block was detected on ECG. In the coronary angiography, thrombosis of the stent in the proximal RCA was seen. Stenosis detected in the mid-left anterior descending artery was 50% and at the distal part was 60%. The circumflex coronary artery was found normal. Percutaneous transluminal coronary angioplasty was performed to the 95% thrombotic lesion in the stent of the proximal RCA, and full patency was established. In our case, a decreasing elevation in the ST segment elevation from V1 to V4 was seen. Right ventricular MI usually occurs by an acute stenosis of the non-dominant proximal RCA branch that does not receive collateral flow. In our case, RCA was codominant and an acute stenosis of the stent in the proximal RCA was present. The occlusion of the non-dominant RCA can appear as isolated right ventricular MI without causing a left ventricular infarct, since it does not feed the left ventricle.

The insertion of ventriculoatrial (VA) shunts for the treatment of hydrocephalus is associated with the development of chronic thromboembolic pulmonary hypertension (CTEPH). Chronic thromboembolic pulmonary hypertension occurs in patients with recurrent or chronic pulmonary embolism, and is a rare but, potentially devastating disease in children. Pulmonary thromboendarterectomy (PTE) is an important curative therapy for patients with CTEPH. Herein, we present a case of a 14 year-old male patient with CTEPH that developed after a VA shunt procedure. After successful PTE, systolic pulmonary artery pressure was decreased from 75 mmHg to 30 mmHg. PTE is recommended in the pediatric CTEPH population.

Coronary artery fistulas are rare vascular anomalies characterized by abnormal communication, devoid of a capillary system between the coronary artery and the major vessels or cardiac chambers. In this report, we present a 14-year-old male patient with ischemic symptoms, a left coronary artery to right ventricle fistula and agenesis of the right coronary artery. The anatomy of the coronary arteriovenous fistula was determined in detail through a dual source CT coronary angiography. The patient underwent open cardiac surgery because of ischemic symptoms and a residual fistula was detected after the surgery.

Ectopic kidneys are rare and usually present incidental findings during invasive or non-invasive angiography. Their parenchyma is not more susceptible to disease and symptoms occur mainly due to alteration of the anatomic relations. The main renal artery of the ectopic kidney derives invariably from the aorta; however, accessory renal arteries may originate from almost any arterial branch adjacent to the ectopic kidney. Knowledge of the common anatomic variations is important during complex peripheral interventions. We present the case of a 46-year-old male with symptoms of claudication secondary to left common iliac artery occlusion. He was diagnosed as occlusion of the left common iliac artery at the aortoiliac bifurcation in close proximity to the ectopic renal artery by peripheral angiography, and percutaneous intervention of the left common iliac artery was successful. Percutaneous intervention led to resolution of the patient’s symptoms of claudication as well as preservation of the ectopic renal artery. In such cases, renal ectopy and aberrant arteries should be promptly recognized in order to avoid vascular or renal complications.

In recent years, the use of herbal combinations, plant extracts or food supplements has increased in our country and all over the world. However, there is not enough data to determine the effective doses of these substances in the composition of herbal preparations, or their effects on metabolism and drug interactions. With the widespread use of herbal combinations, life-threatening side effects and clinical manifestations that arise from them have been reported. Herein we present a case with acute massive pulmonary embolism while using an herbal combination in the context of Tribulus terrestris, Avena sativa and Panax ginseng. A 41-year-old man was admitted to the emergency department with the complaint of sudden onset of dyspnea and syncope. As a result of investigations (blood gases, echocardiography, ventilation-perfusion scintigraphy) he was diagnosed with an acute massive pulmonary embolism. The patient’s use of panax did not pose as a risk factor for the pulmonary embolism. He was given thrombolytic therapy and shortness of breath improved. At the pre-discharge the patient was informed of the risks associated with the herbal combination, especially panax. Coumadin was started and he was discharged for the INR checks to come.

All prosthetic valves are at least mildly stenotic and have relatively high transvalvular pressure gradients that can be observed despite normal prosthesis function. Such gradients may be due to a mismatch between prosthesis effective orifice area (EOA) and patient’s body size. Valve prosthesispatient mismatch (VP-PM) may occur due to mismatches of both parameters, the expected hemodynamic performance of the prosthesis and the cardiac output requirements of the patient, which are largely related to the body size at rest. In other words, a prosthesis may be adequate for patients with a small body surface area (BSA) but might become obstructive for patients with a large BSA. The only parameter that has proven to be consistently and realistically useful to predict and describe VP-PM is the effective orifice area index (EOAI). The projected EOAI was identified as the best parameter to predict the VP-PM occurrence after surgery. VP-PM has been known to be independently and significantly associated with clinical outcomes. Severe VP-PM has a significant impact on early and late mortality, whereas moderate VP-PM may have a significant effect on mortality only in vulnerable subsets of patients, and particularly in those with depressed LV systolic function. The surgeon’s anticipation of VP-PM prior to surgery, and successfully implented preventive strategies can reduce the incidence of VP-PM. Preventive strategies to avoid VPPM should be individualized according to the anticipated severity of VP-PM and of the patient’s baseline risk profile.

We congratulate the authors of the paper titled ‘’Epidemiology of atrial fibrillation in Turkey: preliminary results of the multicenter AFTER study’’ which has evaluated 2242 consecutive patients with at least one atrial fibrillation (AF) in17 different tertiary health care centers (1).
However, we have a few concerns about the study:
