Baseline aortic pre-ejection interval predicts reverse remodeling and clinical improvement after cardiac resynchronization therapy
Background: Cardiac resynchronization therapy (CRT) has been shown to reduce heart
failure-related morbidity and mortality. However, approximately one in three patients do not
respond to CRT. The aim of the current study was to determine the parameter(s) which predict
reverse remodeling and clinical improvement after CRT.
Methods: A total of 54 patients (43 male, 11 female; mean age 61.9 ± 10.5 years) with heart
failure and New York Heart Association (NYHA) class III–IV symptoms and in whom left
ventricular ejection fraction (LVEF) was £ 35% and QRS duration was ≥ 120 ms, despite
optimal medical therapy, were enrolled. An echocardiographic examination was performed
before, and six months after, CRT. An echocardiographic response was defined as a reduction
of end-systolic volume ≥ 10% after six months, and a clinical response was defined as
a reduction ≥ 1 in the NYHA functional class score.
Results: An echocardiographic response was observed in 38 (70.4%) of the patients and
a clinical response occurred in 41 (75.9%) of the patients. Of the dyssynchrony parameters,
only the aortic pre-ejection interval (APEI) was observed to significantly predict the clinical
response (p = 0.048) and echocardiographic response (p = 0.037). A 180.5 ms cut-off value
for the APEI predicted the clinical response with a sensitivity of 92.3% and a specificity of
39%, and the echocardiographic response with a sensitivity of 93.0% and a specificity of 42%.
Conclusions: APEI derived from pulsed-wave Doppler, which is available in every echocardiography
machine, is a simple and practical method that could be used to select patients for CRT.

Total white blood cell count is associated with the presence, severity and extent of coronary atherosclerosis detected by dual-source multislice computed tomographic coronary angiography
Background: Total white blood cell (WBC) count has been consistently shown to be an
independent risk factor and predictor for future cardiovascular outcomes, regardless of disease
status in coronary artery disease (CAD). The purpose of this study is to evaluate the relationship
between total WBC count and the presence, severity and extent of coronary atherosclerosis
detected in subjects undergoing multislice computed tomographic (MSCT) coronary angiography
for suspected CAD.
Methods: A total of 817 patients were enrolled in this cross-sectional study. Non-significant
coronary plaque was defined as lesions causing £ 50% luminal narrowing, and significant
coronary plaque was defined as lesions causing > 50% luminal narrowing. For each segment,
coronary atherosclerotic lesions were categorized as none, calcified, non-calcified and mixed.
All images were interpreted immediately after scanning by an experienced radiologist.
Results: An association between hypertension, diabetes mellitus, age, gender, hyperlipidemia,
smoking, total WBC counts and coronary atherosclerosis was found when patients were
grouped into two categories according to the presence of coronary atherosclerosis (p < 0.05).
Although plaque morphology was not associated with total WBC counts, the extent of coronary
atherosclerosis was increased with higher total WBC quartiles (p = 0.006). Patients with
critical luminal stenosis had higher levels of total WBC counts when compared to patients with
non-critical luminal narrowing (7,982 ± 2,287 vs 7,184 ± 1,944, p < 0.05).
Conclusions: Our study demonstrated that total WBC counts play an important role in
inflammation and are associated with the presence, severity and extent of coronary atherosclerosis
detected by MSCT. Further studies are needed to assess the true impact of WBC counts
on coronary atherosclerosis, and to promote its use in predicting CAD. (Cardiol J 2011; 18, 4:

Left Atrial Appendage Transcatheter Occlusion with AMPLATZER™ Amulet™ Device
Background Left atrial appendage (LAA) occlusion is an alternative therapy for atrial fibrillation patients who have high embolic risk and contraindications to anticoagulant therapy. Objective To evaluate the feasibility, safety, and mid-term outcomes of percutaneous LAA occlusion, including device-related thrombosis. Methods Sixty consecutive patients who had undergone percutaneous LAA occlusion with AMPLATZER™ Amulet™ device from September 2015 to March 2018 were enrolled. Patients were followed for 21 ± 15 months (median - 20 months, interquartile range - 9 to 27 months). The postprocedural assessment was done at the 1st, 6th, and 12th month. Patients were clinically evaluated, and transesophageal echocardiography was performed at each visit. We evaluated the condition of normality of variables using the Kolmogorov-Smirnov test. P-values 3 mm) at the 1st month evaluation, which disappeared at the 12th month follow-up. Conclusion We concluded that LAA occlusion using the Amulet™ LAA occluder can be performed with high procedural success and acceptable outcomes.PubMedWoSScopu
Physical inactivity and low quality of life in Turkish women after hospitalization for coronary heart disease: inferences from EUROASPIRE III
Objective: The present objective was to compare changes in lifestyle between (i) Turkish women and Turkish men, and (ii) Turkish women and European women, after hospitalization for coronary heart disease (CHD). Risk factor management, physical activity, mood, and quality of life (QOL) indices were compared
Pulmonary Balloon Valvuloplasty In A Pregnant Woman With Severe Pulmonary Stenosis
Pulmonary valvular stenosis is a rare valvular disease; it accounts for 7% to 12% of all patients with congenital heart disease. Patients with mild or moderate pulmonary stenosis (PS) are usually asymptomatic and the stenosis is often detected incidentally with echocardio-graphy performed for another reason. Severe PS typically presents with symptoms related to increased right ventricular pressure and right heart failure. Valvular heart diseases are associated with increased morbidity and mortality in pregnancy due to cardiovascular alterations that occur during the gestational period, such as increased extracellular volume, a faster heart rate, and decreased venous return due to compression of the vena cava inferior by the enlarged uterus. While mild or moderate PS can be well tolerated in pregnancy, severe PS can lead to maternal and fetal perinatal complications. Presently described is the case of a pregnant patient with severe PS who successfully underwent balloon valvuloplasty in the third trimester.WoSScopu
The Diagnostic and Prognostic Value of First Hour Glycogen Phosphorylase Isoenzyme BB Level in Acute Coronary Syndrome
Background: Evaluating patients with symptoms suggestive of acute coronary syndrome (ACS) is a time consuming, expensive and problematic process in the emergency department. This study aimed to evaluate the diagnostic and prognostic value of glycogen phosphorylase isoenzyme-BB (GP-BB) in ACS. Methods: A total of 72 patients (mean age 61.8 +/- 11.6 years) with ACS were enrolled. The ELISA method for determining GP-BB level was performed and considered positive at > 10 ng/mL. Duration of angina, type of ACS, demographic features, myoglobin, creatinine kinase and troponin T (cTnT) were also assessed. The cTnT levels eight hours after pain onset was considered the gold standard test for the diagnosis of myocardial infarction. Results: The most sensitive biomarker at first hour of admission was GP-BB (95.8%). However, the specificity of GP-BB was low (43.7%). Receiver operating characteristics curve analysis of the GP-BB level for predicting myocardial infarction revealed the area under the curve value as 0.82 (SE 0.04; 95% CI 0.78-0.85). Positive treadmill exercise test (60% vs 17%, p = 0.047), coronary artery disease (CAD; 59% vs 19%, p = 0.007), percutaneous coronary intervention (44% vs 27%, p = 0.031) and 30-day mortality and/or readmission (33% vs 5%, p = 0.028) were found to be higher in unstable angina (UA) patients having GP-BB (+). Conclusions: GP-BB is considerably cardiosensitive at the first hour of admission in patients with ACS, but the specificity of GP-BB is lower and it is elevated in nearly half of the patients with UA. However, in this group, GP-BB predicts significant CAD and the combined end-point of mortality and re-hospitalization. (Cardiol J 2011; 18, 5: 496-502)WoSScopu

The Use Of Amplatzer Vascular Plug (R) To Treat Coronary Steal Due To Unligated Thoracic Side Branch Of Left Internal Mammary Artery: Four Year Follow-Up Results
Left internal mammary artery (LIMA) is the most commonly used graft during coronary bypass surgery. LIMA side branches are clipped during surgery in order to prevent coronary steal. In cases of patent LIMA side branches, there are differingapproaches. Herein, we report a case with patent thoracic side branch of LIMA graft, occlusion of this side branch by Amplatzer Vascular Plug (R) because of documented myocardial ischemia, and long term follow-up results.

Brugada Syndrome with Aborted Sudden Cardiac Death Related to Liquorice-Induced Hypokalemia
Objective: It was the aim of this study to report an aborted cardiac arrest due to ventricular fibrillation and electrocardiographic changes consistent with Brugada syndrome due to liquorice-induced hypokalemia. Clinical Presentation and Intervention: Ventricular fibrillation was witnessed in a 50-year-old woman who was admitted to our emergency department with a history of liquorice ingestion, a herbal product. After stopping liquorice ingestion, the Brugada-like electrocardiographic pattern changed progressively with potassium replacement. A diagnosis of Brugada syndrome was made after the ajmaline challenge test. The patient was discharged with an implantable cardioverter defibrillator and had an uneventfull follow-up. Conclusion: This report illustrates the importance of the investigation for herbal medications in the detailed history of a patient in the cases of electrolyte disturbances and the potential role of hypokalemia in the induction of malignant arrhythmia in Brugada syndrome.
