RESUMEN
Introduction: We would like to present video-assisted thoracoscopic surgery for the treatment of pericardial hydatid cyst.Patient and Method: Thirty two-year-old female patient was referred for evaluation of a left mediastinal mass. Magnetic resonance image, computed tomography and transesophageal echocardiography confirmed a well circumscribed mass with compatible hydatid cyst at the left pericardial wall end of the differantial diagnosis. Our surgical plan entailed the endoscopic resection of pericardial hydatid cyst. We did not adopt a more precise strategy such as open procedure. We managed removal of the hydatid cyst by using video assisted thoracoscopic surgery.Results: The patient has been doing well for 4 years now after her surgery.Conclusion: We think that endoscopic approach is an effective treatment modality for pericardial hydatid cyst.

OBJECTIVE: The aim of this study was to determine the relationship between serum uric acid (UA) level and the predicted risk score for sudden cardiac death in 5 years (the HCM Risk-SCD), galectin-3 level, and positive fragmented QRS (fQRS) on electrocardiography (ECG) in patients with hypertrophic cardiomyopathy (HCM). METHODS: This was a prospective, observational study. In all, 115 consecutive patients (age >17 years) with HCM and 80 healthy participants were included in the study. The HCM Risk-SCD score (%), galectin-3 level, and fQRS on ECG were evaluated in all patients. RESULTS: The serum UA, galectin-3 level, UA/Creatinine ratio, incidence of ventricular tachycardia (VT) and syncope, and some echocardiographic parameters were significantly higher in the patient group than in the control group (all p<0.05). The UA value was significantly higher in patients with a high score on the HCM Risk-SCD, a positive fQRS, a high galectin-3 level, VT incidence, and need for implantable cardioverter defibrillator (ICD) implantation or cardiopulmonary resuscitation (CPR) than in those without (HCM Risk-SCD >6%. Namely, HCM Risk-SCD >6%, UA: 6.71±1.29 mg/dL, HCM Risk-SCD ≤5.9%, UA: 5.84±1.39 mg/dL, p=0.001; fQRS(+), UA: 6.56±1.20 mg/dL, fQRS(-), UA: 5.63±1.49 mg/dL, p<0.001; galectin-3 >6.320 pg/mL, UA: 6.56±1.27 mg/dL, galectin-3 ≤6.310 pg/mL, p=0.016; left atrium anterior-posterior dimension (LAAPD) >36 mm, UA: 6.31±1.33 mg/dL, LAAPD <36 mm, UA: 5.20±1.60 mg/dL, p=0.005; VT(+), UA: 6.83±1.19 mg/dL, VT(-), UA: 5.97±1.42 mg/dL, p=0.008; ICD(+), UA: 7.08±0.88 mg/dL, ICD(-), UA: 6.06±1.42 mg/dL, p=0.022; CPR(+), UA: 7.03±0.96 mg/dL, CPR(-), UA: 6.04±1.42 mg/dL, p=0.018. A statistically significant correlation was observed between UA and HCM Risk-SCD, galectin-3 level, LAAPD, and left ventricular (LV) mass (LVM) (r and p values, respectively: 0.355, <0.001; 0.297, 0.002; 0.309, 0.001; 0.276, 0.003. CONCLUSION: The serum UA level was significantly higher in patients with HCM compared with the control group. A high UA level was associated with a higher HCM Risk-SCD score, positive fQRS, higher galectin-3 level, greater LAAPD, VT incidence, and the need for ICD implantation and CPR in patients with HCM.

BACKGROUND: The left internal thoracic artery (LITA) is the most commonly used arterial bypass conduit in coronary artery bypass graft (CABG) patients and inadequate LITA flow can result in an increase in morbidity and mortality. In this study, we evaluated the effect of excision of the distal spasmodic segment of the LITA on the free flow in CABG patients. METHODS: This study consisted of 47 patients who underwent elective CABG performed with or without other cardiac surgery, between July 2015 and December 2015. Excised LITA length was shorter than 15mm in group 1, between 15mm and 30mm in group 2 and longer than 30mm in group 3. Left ITA free flow was measured for 60seconds into a container before and after the distal LITA excision. The inter-measurement differences were calculated for the three groups. Thereafter, the comparison was performed in terms of free flow difference amongst the three groups. RESULTS: The mean difference of LITA free flow was 27.6±22.7ml/minute in group 1, 35.4±26.7ml/minute in group 2, and 52.6±26.1ml/minute in group 3. There were significant differences in terms of free flow difference between the groups (p=0.008). Also, differences were statistically significant in group 1 versus group 3 (p=0.003) and group 2 versus group 3 (p=0.038) in the intergroup comparisons. CONCLUSIONS: The distal part of the LITA has more spasmodic potential than other segments. This spasm may result in low flow of LITA grafts. Therefore, an as long as possible excision of the distal LITA segment may be required to avoid the spasmodic effect.

BACKGROUND: Asymmetric dimethylarginine (ADMA) is an endogenous inhibitor of nitric oxide synthase. AIM: We aimed to determine plasma ADMA levels in patients with ascending aorta dilatation in comparison to those without aorta dilatation, and to evaluate the diagnostic, predictive, and prognostic value of serum ADMA level for aorta dilatation. METHODS: This was a cross-sectional case-control study. A total of 104 consecutive patients (female/male, 35/69; mean age, 62.75 ± 13.11 years) diagnosed with ascending aorta dilatation (≥ 4.5 cm) on echocardiography (case group), and 52 age-and gender-matched patients (female/male, 17/35; mean age, 63.44 ± 7.56 years) with normal aorta dimensions (≤ 3.8 cm) (control group) were included. Routine biochemical and haematological analysis in addition to measurement of serum ADMA level were performed. RESULTS: The mean diameter of ascending aorta measured on echocardiography was 4.95 ± 0.57 cm and 3.34 ± 0.36 cm in patients with aorta dilatation and those without aorta dilatation, respectively (p < 0.001). Serum ADMA level was significantly higher in patients with aorta dilatation than in the control group (1.70 ± 1.12 µmol/L vs. 0.79 ± 0.76 µmol/L, respectively, p < 0.001). There was significant positive correlation between ADMA level and aortic diameter in Spearman correlation analysis (r = 0.317, p < 0.001). In linear regression analysis, ADMA was found to be a significant independent predictor of aorta diameter (Beta = 0.26, p < 0.001). Receiver-operator characteristic curve analysis also revealed that serum ADMA cut-off level over 0.29 µmol/L predicts aorta dilatation (≥ 4.5 cm) with 94% sensitivity and 92% specificity and with high ac-curacy (area under curve: 0.786; 95% confidence interval: 0.709-0.863, p < 0.001). CONCLUSIONS: Serum ADMA level is diagnostic for ascending aorta dilatation with high sensitivity and specificity, and should be considered for use in clinical diagnosis of aorta dilatation.

PURPOSE: To determine the predictive values of D-dimer assay, Global Registry of Acute Coronary Events (GRACE) and Thrombolysis in Myocardial Infarction (TIMI) risk scores for adverse outcome in patients with non-ST-segment elevation myocardial infarction (NSTEMI). PATIENTS AND METHODS: A total of 234 patients (mean age: 57.2±11.7 years, 75.2% were males) hospitalized with NSTEMI were included. Data on D-dimer assay, GRACE and TIMI risk scores were recorded. Logistic regression analysis was conducted to determine the risk factors predicting increased mortality. RESULTS: Median D-dimer levels were 349.5 (48.0-7,210.0) ng/mL, the average TIMI score was 3.2±1.2 and the GRACE score was 90.4±27.6 with high GRACE scores (>118) in 17.5% of patients. The GRACE score was correlated positively with both the D-dimer assay (r=0.215, P=0.01) and TIMI scores (r=0.504, P=0.000). Multivariate logistic regression analysis revealed that higher creatinine levels (odds ratio =18.465, 95% confidence interval: 1.059-322.084, P=0.046) constituted the only significant predictor of increased mortality risk with no predictive values for age, D-dimer assay, ejection fraction, glucose, hemoglobin A1c, sodium, albumin or total cholesterol levels for mortality. CONCLUSION: Serum creatinine levels constituted the sole independent determinant of mortality risk, with no significant values for D-dimer assay, GRACE or TIMI scores for predicting the risk of mortality in NSTEMI patients.
RESUMEN
INTRODUCTION: Previous studies have demonstrated the predictive value of the neutrophil-to-lymphocyte ratio (NLR) in many cardiovascular disorders. The aim of this study was to assess whether NLR is associated with echocardiographic or electrocardiographic parameters, or with predicted five-year risk of sudden cardiac death (SCD), in patients with hypertrophic cardiomyopathy (HCM). METHODS: This prospective observational study included 74 controls and 97 HCM patients. Three years of follow-up results for HCM patients were evaluated. RESULTS: NLR was significantly higher in patients with fragmented QRS, ventricular tachycardia, and presyncope than in those without (p=0.031, 0.030, and 0.020, respectively). NLR was significantly higher in patients whose predicted five-year risk of SCD was more than 6% and whose corrected QT interval was greater than 440 ms (p=0.022 and 0.001, respectively). It was also significantly higher in patients whose left ventricular ejection fraction (LVEF) was <60% than in those with LVEF >60% (p=0.017). CONCLUSION: NLR was significantly higher in patients with HCM compared to the control group. A high NLR is associated with a higher five-year risk of SCD in patients with HCM.

BACKGROUND: The purpose of this study is to assess the electrocardiographic and electrophysiological parameters of conduction abnormalities in patients undergoing transcatheter aortic valve implantation (TAVI) due to severe aortic valve stenosis. METHODS: The study included 55 patients who underwent TAVI using either the Boston Scientific Lotus (n:25) (Boston Scientific, Natick, MA, USA) or Edwards Sapien XT (n:30) (Edwards Lifesciences, Irvine, CA, USA) prostheses. An electrophysiological study (EPS) was performed in the catheterization room immediately before the initial balloon valvuloplasty and immediately after prosthesis implantation. RESULTS: QRS duration and His-bundle to His-ventricle (HV) intervals, which were similar between the two groups before the procedure, were found to be significantly higher in the Lotus valve group postprocedure. Permanent pacemakers (PPMs) were required more frequently in the Lotus group than in the Sapien XT group at discharge (24.0% vs 6.7%, P = 0.07). With the exception of a higher prevalence of paravalvular leakage (P < 0.001) in patients undergoing Sapien XT implantation, other clinical outcomes were similar between the two groups. Multiple regression analysis revealed that baseline atrioventricular (AV) conduction disorders and HV intervals after the procedure were independently associated with PPM implantation after TAVI. CONCLUSION: In this first study comparing the findings of EPS and electrocardiography, the impact of the Lotus valve on AV conduction systems was greater than that of the Sapien XT. However, the need for PPM was higher in the Lotus valve than in the Sapien XT. PPM requirement is related to valve design; it may decrease with reduced frame height and metal burden in novel valve systems.

OBJECTIVES: In this randomized, controlled and parallel-group prospective study, the feasibility of total pericardial closure with an intrapericardial drain and a pericardio-pleural window (pericardial cavity intervention) was investigated by examining postoperative outcomes, including atrial fibrillation and pericardial effusion, following coronary artery surgery. METHODS: Cases were classified into two groups using a random procedure: the closure group and the open group. Insertion of an intrapericardial drain along the right atrium, pericardio-pleural window and total closure of the pericardium were performed in patients in the closure group. Partial closure of the pericardium was performed in patients in the open group. A straight semi-rigid drain was inserted into the extrapericardial anterior mediastinum and a right angle drain was inserted into the left chest in all patients. The primary endpoint was to evaluate the impact of surgical technique on the rate of postoperative in-hospital atrial fibrillation in the closure group. The secondary endpoint was to evaluate the relationship between the surgical technique and postoperative amount of pericardial effusion. RESULTS: A total of 142 isolated, on-pump cases were examined: 72 in the open group and 70 in the closure group. Postoperative atrial fibrillation occurred in 27.78% of the cases in the open group and 8.57% of the patients in the closure group (P = 0.003). Another statistically significant outcome was the lower incidence of small pericardial effusion in the patient group with a closed pericardium during the second day of postoperative care (P = 0.039). The length of both critical care unit (P = 0.008) and hospital stay (P = 0.047) were also significantly shorter in the patient group with a closed pericardium. CONCLUSIONS: Total pericardiorrhaphy with pericardial cavity intervention can be acceptable and favourable in terms of its outcomes, including reducing incidence of postoperative atrial fibrillation, pericardial effusion and length of hospitalization.

BACKGROUND: The beneficial effects of the transcatheter aortic valve implantation (TAVI) on echocardiographic parameters including left atrial (LA) and left ventricular (LV) functions were described by previous studies. The aim of this study was to analyze the effects of TAVI on left atrial appendage (LAA) function assessed by transthoracic and transesophageal echocar-diography. METHODS: Fifty-five patients with severe symptomatic aortic stenosis were included in this prospective study. LAA early and late emptying velocities, LAA filling velocity, peak early diastolic (EM), late diastolic (AM), and systolic (SM) velocities were measured with pulsed wave Doppler and tissue Doppler imaging, and E/Em ratio was calculated before and 7.1 ± 2.8 days after TAVI. A subgroup analysis was performed in accordance with the left ventricular ejection fraction (LVEF) of the patients and the severity of their LV diastolic dysfunction. RESULTS: Although the post-procedure peaks and mean gradients of the patients decreased sig-nificantly, the LVEF increased significantly in those who had low LVEF before the procedure. The post-procedure E/Em ratio decreased significantly (p < 0.001). The post-procedural LAA mean filling velocity and EM velocity were significantly higher than the pre-procedural filling velocity (p < 0.001, p = 0.002, respectively). In the subgroup analysis, the post-procedural LAA filling velocity, early and late LAA emptying velocities, in addition to the mean velocity of the EM, AM, and SM were significantly higher than before the procedure in patients with LVEF of < 50% and E/Em ratios of > 15. CONCLUSIONS: LAA function improved soon after the TAVI procedure, especially in patients with low LVEF and marked LV diastolic dysfunction.

BACKGROUND: The coronary slow flow (CSF) phenomenon is a delayed antegrade progression of contrast agent to the distal branch of a coronary artery in the absence of obstructive coronary artery disease (CAD). A narrow fragmented QRS (fQRS) has been reported as a significant predictor of sudden cardiac death in patients with idiopathic dilated cardiomyopathy. The present study aimed to investigate the relationship between a narrow fQRS on the admission electrocardiogram (ECG) and CSF on coronary angiography. METHODS: This study included 165 consecutive patients (112 CSF, 53 controls) who underwent first-time diagnostic conventional coronary angiography for suspected CAD. Coronary flow was quantified by thrombolysis in myocardial infarction (TIMI) frame count (TFC). The patients were divided into two groups according to the presence or absence of a narrow fQRS complex on the admission ECG. RESULTS: Forty four patients were in the fQRS group (mean age, 52.97 ± 3.13 years). There was no difference between the two groups with respect to age, gender, body mass index, family history, hyperlipidemia, hypertension, or diabetes mellitus. The extent of CSF was significantly greater in the fQRS group compared to the non-fragmented group (p < 0.001). A significant correlation was also found between mean TFC values and fQRS (p < 0.001). On multivariate analysis, only CSF (p = 0.03) was a significant independent predictor for narrow fQRS, after adjustment for other parameters. CONCLUSIONS: The narrow fQRS is a simple, inexpensive, and readily available noninvasive ECG parameter that may be a new potential indicator of myocardial damage in patients with CSF.

BACKGROUND: Fragmented QRS (fQRS) arises from impaired ventricular depolarization due to heterogeneous electrical activation of ischemic and/or infarcted ventricular myocardium. The short- and long-term prognostic values of fQRS have been reported for myocardial infarction, heart failure, fatal cardiac arrhythmias, and sudden cardiac death. The aim of this study was to investigate the predictive value of admission fQRS complex for in-hospital cardiovascular mortality of patients with type 1 acute aortic dissection (AAD). METHODS: In this retrospective study, 203 consecutive patients with type 1 AAD who had been admitted to either of two large-volume tertiary hospitals between December 2008 and October 2013 were included. The patients were divided into two groups according to the presence or absence of the fQRS complex on admission. RESULTS: In-hospital cardiovascular mortality (P < 0.001), major adverse cardiovascular events (P < 0.001), acute renal failure (P = 0.022), multiorgan dysfunction (P < 0.001), and acute decompensated heart failure (P < 0.001) were observed to be significantly more frequent in the fQRS-positive group than in the fQRS-negative group. fQRS (odds ratio [95% confidence interval]: 4.184 [1.927-9.082], P < 0.001), operation duration (4.184 [1.927-9.082], P = 0.001), and Killip class IV (3.900 [1.699-8.955], P = 0.001) were found to be significant independent predictors of in-hospital cardiovascular mortality after adjustment of other risk factors in the multivariate analysis. CONCLUSIONS: fQRS is a simple, inexpensive, and readily available electrocardiographic entity that provides an additional risk stratification level beyond that provided by conventional risk parameters in predicting in-hospital cardiovascular mortality in type 1 AAD.

INTRODUCTION: Pericardial effusion and atrial fibrillation occur commonly after coronary artery surgery. AIM OF THE STUDY: A prospective randomized clinical trial was conducted to evaluate the effects of posterior pericardiotomy on the occurrence of pericardial effusion, tamponade, and atrial fibrillation. MATERIAL AND METHODS: The study group consisted of 96 patients (77 male and 19 female) at a mean age of 58.1 ± 9.8 years. The patients were randomly assigned to one of three study groups: patients undergoing posterior pericardiotomy (group I, n = 30), controls (group II, n = 33), and patients with additional posterior pericardial drainage tubes (28 mm) who did not undergo posterior pericardiotomy (group III, n = 33). RESULTS: Postoperative hospitalization (p = 0.03; 11.56 ± 10.64) and reoperation due to tamponade (p = 0.019; 12.1%) were significantly higher in group II. Extensive pericardial effusions were detected in one patient on the first postoperative day (group II, n = 1), in one patient on the fifth postoperative day (group III, n = 1), and in one patient on the 30(th) day after the operation (group III, n = 1). Pericardial effusion exhibited regression in group I on postoperative day 30 (p = 0.028). A higher rate of postoperative atrial fibrillation was noted in group I, but no significant differences were found between the groups with regard to postoperative atrial fibrillation. CONCLUSIONS: Patients who did not undergo posterior pericardiotomy or did not receive posterior chest tubes exhibited residual pericardial effusion, required longer hospitalization, and had to be reoperated due to tamponade. Both posterior pericardiotomy and the use of posterior tubes are effective in the early postoperative period.
RESUMEN
BACKGROUND: Isovolumic acceleration (IVA) is a new tissue Doppler parameter in the assessment of systolic function of both left and right ventricles. It remains unaffected with the changes in pre- and after-load within the physiological range. The aim of our study was to assess the effect of mitral stenosis degree, which is determined by echocardiography, on the left ventricular (LV) function using IVA. METHODS: A total number of 62 patients with mitral stenosis (MS) and 32 healthy controls were examined. The severity of MS (mild, moderate, and severe) was determined on the basis of mitral valve area (MVA) and the mean diastolic mitral gradient findings. The peak myocardial velocities during isovolumic contraction, systole, early diastole and late diastole were measured by using tissue Doppler imaging (TDI). RESULTS: All TDI-derived global LV basal wall systolic (peak myocardial isovolumic contraction velocity, peak myocardial systolic velocity and IVA), and diastolic velocities (peak early and late diastolic velocities) were significantly decreased in the patients with MS, compared to the healthy patients (p < 0.001, for all). However, IVA was not different when the degree of MS was evaluated (p = 0.114). In addition, IVA was not correlated with the MVA (r = 0.185, p = 0.150). CONCLUSIONS: Left ventricular function is impaired in patients with MS regardless of the severity of the disease.
