RESUMEN
BACKGROUND: Transcatheter aortic valve implantation (TAVI) is currently the treatment of choice for the majority of patients at moderate or high surgical risk. However, some complications occur frequently with this procedure. In this study, we aimed to assess whether the cusp-overlap view (COP) technique may be associated with a reduced incidence of some of these complications compared with the classical three-cusp view (TCV) technique. METHODS: In this single-center, retrospective study we investigated; technical success, postprocedural permanent pacemaker implantation (PPMI), new-onset stroke, pericardial tamponade, arrhythmia development, acute renal failure, major bleeding, major vascular complications, procedure-related coronary obstruction, new-onset left bundle branch block (LBBB), paravalvular leak, peri-procedural myocardial infarction (MI), day of hospitalization, death, and major adverse cardiac and cerebrovascular events (MACCE) were determined as the clinical endpoints. RESULTS: A total of 281 consecutive patients who met the study criteria and underwent elective or emergency transfemoral TAVI using the self-expandable CoreValve Evolut valve were included. 176 consecutive patients implanted with the classical TCV technique and 105 consecutive patients implanted with the COP technique were compared. Compared with the TCV group, patients in the COP group had lower PPMI (3.8% vs. 10.8%, p = 0.039), in-hospital mortality (1.9% vs. 8.5%, p = 0.018), and 1-year death (4.8% versus 18.8%, p = 0.001), and MACCE rates (12.4% vs 31.3%, p < 0.001). CONCLUSION: The COP technique may help to reduce the conduction disturbances, PPMI requirement and complication rates that may develop following TAVI. In addition, it is an interesting result that it reduces mortality and MACCE rates in long-term follow-ups.

Objective The prognostic nutritional index (PNI) is a practical, applicable, prognostic scoring system. However, its clinical significance in unprotected left main coronary artery (ULMCA) patients undergoing percutaneous coronary intervention (PCI) has not yet been clarified. This study aimed to examine the relationship between malnutrition as assessed by PNI and major adverse cardiac events (MACE) in ULMCA patients undergoing PCI.Material and methods 185 patients who were hospitalized in our clinic underwent coronary angiography, had a critical LMCA lesion, and underwent angiography-guided PCI were included. The study population was divided into tertiles based on the PNI values. A high PNI (n=142) was defined as a value in the third tertile (≥ 34.0), and a low PNI (n=43) was defined as a value in the lower 2 tertiles (< 34.0). The primary endpoint was MACE.Results MACE and mortality rates in the low PNI group were significantly higher compared to the high PNI group (51â% vs. 30â%, p=0.009; 44â% vs. 20â%, p=0.002, respectively). High PNI (HR:1.902; 95â% CI:1.112-3.254; p=0.019), previous stroke (HR:3.025; 95â% CI:1.038-8.810; p=0.042) and SYNTAX score (HR:1.028; 95â% CI:1.004-1.057, p=0.023) were independent predictors of MACE in the multivariable cox regression analyzes.Conclusions In patients undergoing ULMCA PCI, nutritional status can be considered an indicator of MACE rates by evaluating the PNI score. This index can be used for risk classification.

BACKGROUND: T-wave inversion in lead III was linked to displacement of the base of the heart due to abdominal adipose tissue in early electrocardiography (ECG) trials. The observation of T-wave inversion in lead III in some of the pathological and physiological conditions other than obesity suggests the possibilities of different mechanisms. We aimed to investigate the prevalence and correlates of T-wave inversion in lead III in non-obese men. METHOD: A total of 1240 men underwent ECG, blood pressure measurement, hepatic ultrasonography, and biochemical tests from January 2019 to December 2019. We excluded 220 subjects due to predetermined criteria. The eligible 105 non-obese men with T-wave inversion in lead III and 915 non-obese men without T-wave inversion in lead III were compared with each other in terms of clinical, demographic and laboratory parameters. RESULTS: The mean age was 27.9 years with a range of 20 to 46 years. The prevalence of T-wave inversion in lead III was 10.3%. Body mass index (BMI), blood urea nitrogen, creatinine, alanine aminotransferase, hematocrit, and the percentage of non-alcoholic fatty liver disease (NAFLD) were significantly higher in Group with T-wave inversion while alkaline phosphatase was significantly higher in Group without T-wave inversion. In multivariable analysis, NAFLD was the best independent correlate of inverted T-wave in lead III (ß = 6.215, p < 0.0001). BMI (ß = 1.448, p < 0.001) and hematocrit (ß = 1.179, p = 0.021) were the other independent correlates of T-wave inversion in lead III. CONCLUSION: We demonstrated the association of T-wave inversion in lead III with NAFLD, BMI, and hematocrit in non-obese men.

OBJECTIVES: Dual-chamber pacing is believed to have an advantage over single-chamber ventricular pacing. The aim of this study was to determine whether elderly patients who have implanted pacemakers for complete atrioventricular block gain significant benefits from dual-chamber (DDD) pacemakers compared with single chamber ventricular (VVIR) pacemakers. STUDY DESIGN: This study was designed as a randomized, two-period crossover study-each pacing mode was maintained for 1 month. Thirty patients (16 men, mean age 68.87 ± 6.89 years) with implanted DDD pacemakers were submitted to a standard protocol, which included an interview, pacemaker syndrome assessment, health related quality of life (HRQoL) questionnaires assessed by an SF-36 test, 6-minute walk test (6MWT), and transthoracic echocardiographic examinations. All of these parameters were obtained on both DDD and VVIR mode pacing. Paired data were compared. RESULTS: HRQoL scores were similar, and 6MWT results did not differ between the two groups. VVIR pacing elicited significant enlargement of the left atrium and impaired left ventricular diastolic functions as compared with DDD pacing. Two patients reported subclinical pacemaker syndrome, but this was not statistically significant. CONCLUSION: Our study revealed that in active elderly patients with complete heart block, DDD pacing and VVIR pacing yielded similar improvements in QoL and exercise performance. However, after a short follow-up period, we noted that VVIR pacing caused significant left atrial enlargement and impaired left ventricular diastolic functions.

OBJECTIVES: Performing percutaneous mitral commissurotomy (PMC) in the women with asymptomatic severe mitral stenosis (MS) who plan a pregnancy is recommended. However the data regarding this recommendation is limited in the literature. We aimed to investigate maternal and fetal outcomes of women with asymptomatic severe MS who underwent PMC before a planned pregnancy. METHODS: We retrospectively analysed the procedural, pregnancy related, and fetal outcomes of 33 consecutive women with severe asymptomatic MS, age 27.97 ± 2.86 years, who underwent PMC before a planned pregnancy between 2014 and 2019. The control group comprised of 66 pregnant women, age 29.09 ± 3.00 years, without a cardiac disease. RESULTS: The PMC procedure was successful in all patients and no major complication occurred. There were no deaths, pulmonary oedema, heart failure, atrial fibrillation, and thromboembolism during pregnancy. Maternal arrhythmia (p < .001), deterioration in NYHA class (p = .08), and use of cardiovascular medication (p < .001) was significantly higher in the study group. Maternal hospitalisation (p = .435), preeclampsia (p = 1), abortus (p = 1), fetal death (p = 1), and preterm delivery (p = .746) was similar between groups. Birth weight was significantly lower in the PMC group 2890 g (229) vs 3120 g (255) <0.001, however small for gestational age newborns were similar between groups (p = .12). CONCLUSIONS: PMC is safe in asymptomatic women with severe MS planning a future pregnancy. In selected patients with favourable valve anatomy PMC may improve maternal and fetal outcomes.

OBJECTIVE: Hyperbilirubinemia is associated with protection against various oxidative stress-mediated diseases. We aimed to investigate the association between bilirubin and novel electrocardiography (ECG)-based ventricular repolarization parameters. METHODS: We enrolled 201 healthy men with mild hyperbilirubinemia (group 1) and 219 healthy men with normal bilirubin levels (group 2). The Tpeak-Tend (Tp-e) interval (defined as the interval from the peak of the T wave to the end of the T wave), corrected (c) Tp-e interval, QT interval, cQT interval, and Tp-e interval/QT interval ratio were measured from leads V5 and V6 with 20 mm/mV amplitude and 50 mm/second rate. RESULTS: The Tp-e interval, cTp-e interval, and Tp-e interval/QT interval ratio were significantly lower in group 1 compared with group 2. The cTp-e interval showed a significant negative correlation with total bilirubin, conjugated bilirubin, and unconjugated bilirubin. The cTp-e interval (odds ratio [OR], 0.900; Pâ =.002) and Tp-e interval/QT interval ratio (OR, 0.922; Pâ =.04) were significantly associated with mild hyperbilirubinemia. CONCLUSION: We showed the association of mild hyperbilirubinemia with decreased novel ECG-based ventricular repolarization parameters.

We report the results of endovascular treatment of Trans-Atlantic Inter-Society Consensus II (TASC) A&B, TASC C, and TASC D aortoiliac lesions in a single vascular center. In this retrospective, observational cohort study, we analyzed 395 patients (mean age 61.2 ± 9.0; 359 men) between January 2015 and December 2017. Technical success was achieved in 96.5%; in-hospital mortality was 1.2% (n = 5). Median follow-up was 36 months (range 24-49 months). After 1 and 5 years, the primary patency rates were 99% and 85% for TASC A&B, 90%, and 78% for TASC C, and 90% and 74% for TASC D. Secondary patency rates were 99% and 90% for TASC A&B, 98% and 65% for TASC C, and 97% and 65% for TASC D. Previous peripheral revascularization (hazard ratio: 1.76, 95% CI: 1.01-3.08, P = .04) was associated with decreased primary patency along with lower age, TASC C, and TASC D class. This analysis reported the acceptable effectiveness and safety of stenting for all types of aortoiliac occlusive disease in a modern setting, with few complications and excellent long-term primary and secondary patency rates.

OBJECTIVES: We evaluated the prognostic value of N-terminal pro-brain natriuretic peptide (NT-proBNP) for further risk stratification of intermediate-risk patients with non-ST elevation acute coronary syndromes (NSTE-ACS). STUDY DESIGN: The study included 137 intermediate-risk patients (85 men, 52 women; mean age 62+/-11 years) with ACS, based on the TIMI risk score (scores 3 to 5). Serum NT-proBNP levels were measured 12 hours after the last anginal episode. The patients were divided into four groups according to the following NT-proBNP quartiles: 17-310 pg/ml (n=34), 313-688 pg/ml (n=35), 724-2,407 pg/ml (n=34), and 2,575-24,737 pg/ml (n=34). Primary endpoint of the study was mortality. The mean follow-up was 21.8+/-7.1 months. RESULTS: There were 27 deaths (19.7%), 14 of which were in the 4th quartile (4th vs 1st, 2nd, and 3rd quartiles: p=0.02, p=0.01, and p<0.01, respectively). The first three quartiles did not differ significantly in this respect. In Kaplan-Meier analysis, patients in the 4th quartile had the lowest cumulative survival (log rank test, 4th vs 1st, 2nd, and 3rd quartiles: p=0.041, p=0.026, and p=0.009, respectively). NT-proBNP level was significantly higher in nonsurvivors than in survivors (p=0.01). In univariate analysis, mortality was also associated with the TIMI risk score, ejection fraction, and age. Patients who died were older (65.6+/-11.9 years vs 60.7+/-11.0 years; p=0.048) and had a lower ejection fraction (46.3+/-11% vs 54.1+/-9.8%; p<0.001) than patients who survived. Mortality rates corresponding to TIMI risk scores of 3, 4, and 5 were 25.9%, 29.6%, and 44.4%, respectively (p=0.58 for TIMI 3 vs 4; p=0.001 for TIMI 3 vs 5; p=0.013 for TIMI 4 vs 5). Cox proportional hazards regression analysis showed that only TIMI risk score was an independent predictor of mortality (hazard ratio 2.3, 95% confidence interval 1.4-3.8, p=0.001). CONCLUSION: NT-proBNP has an additive predictive value over TIMI risk score in predicting long-term mortality in intermediate-risk patients with ACS.

RESUMEN
OBJECTIVE: The incidence of patent ductus arteriosus (PDA) is greater among patients living at high altitude. In this po-pulation, the ductal diameter is often larger and pulmonary hypertension is more frequent. The aim of this study was to evaluate the hemodynamic and morphological features of PDA and transcatheter closure procedures performed with various devices in a group of patients living at high altitude in Turkey. METHODS: The data of 327 patients who lived at an altitude of at least 1600 m above sea level and who had undergone cardiac catheterization for isolated PDA between May 2010 and July 2018 were retrospectively analyzed. RESULTS: The mean age was 7.33±7.67 years, and 62.4% of the patients were female. The mean ductal diameter was 3.74±2.14 mm. Pulmonary hypertension was present in 57.8%. Transcatheter closure was performed in 322 patients, with a 97.3% success rate. The Amplatzer duct occluder I (ADO I) was used most often, as well as off-label use of the Amplatzer vascular plug II (AVP) and the Amplatzer muscular ventricular septal defect occluder (AMVSDO). Pulmonary artery pressure decreased immediately in the vast majority after percutaneous closure. Transient left ventricular systolic dysfunction after ductal closure was seen only rarely. Follow-up was uneventful. CONCLUSION: Transcatheter PDA closure can be performed with high success rate in highlanders. Off-label devices may be required for these procedures. Pulmonary hypertension is frequent but regresses after ductal closure. Transient left ventricular dysfunction after transcatheter closure is rarely seen in these patients and resolves without any medication.

AIM: The pathophysiology of slow coronary flow (SCF) involves atherosclerosis, small vessel dysfunction, platelet function disorders, and inflammation. It has been known that eosinophils also play a significant role in inflammation, vasoconstriction, thrombosis, and endothelial dysfunction. We propose to evaluate the relationship between eosinophilia and SCF. METHODS: All patients who underwent coronary angiography between January 2011 and December 2013 were screened retrospectively. Of 6,832 patients, 102 patients with SCF (66 males, mean age 52.2±11.7 years) and 77 control subjects with normal coronary angiography (50 males, mean age 50.7±8.1 years) were detected. Baseline characteristics, hematological test results, and biochemical test results were obtained from the hospital database. RESULTS: Baseline characteristics of the study groups were comparable between groups. There was no significant difference between groups regarding leukocyte count, paletelet count, and mean platelet volume. However, patients with SCF had a higher eosinophil count than the controls (0.24±0.17×10(3)/µL vs 0.16±0.15×10(3)/µL, P=0.002). In addition, eosinophil count was found to be correlated with thrombolysis in myocardial infarction (TIMI) frame count in the SCF group (r=0.3, P<0.01). There was no significant correlation between eosinophil count and the number of coronary arteries showing slow flow. CONCLUSION: Patients with SCF have higher blood eosinophil count, and this may play an important role in the pathogenesis of SCF. Elevated baseline eosinophil count may indicate the presence of SCF.
RESUMEN
OBJECTIVE: Although stents reduce the restenosis rate, stent restenosis continues to be a major problem and the optimal treatment of stent restenosis is still controversial. In this study, we aimed to investigate the angiographic recurrent stent restenosis rate at 6-12 months after successful cutting balloon angioplasty (CBA) for the bare metal stent restenosis. METHODS: Thirty patients (mean age: 57.9 ± 11.6, 22 males) undergoing successful CBA for the treatment of in-stent restenosis at our hospital were prospectively included in this study. Control coronary angiography was performed at 6-12 months after CBA. Lesion length, minimal lumen diameter (MLD), and reference vessel diameter were analyzed by computerized digital angiographic analysis. Recurrent restenosis was defined as the lesions obstructing the lumen more than 50%. We described the lesions shorter than 10 mm as to be focal and those longer than 10 mm as to be diffuse. We used Student t, Chi-square, and Mann-Whitney U tests for statistical analysis. RESULTS: Two patients had two distinct lesions; therefore, 32 lesions were assessed. There were 9 (28.1%) recurrent restenosis on the control coronary angiography. Recurrent restenosis developed in 3/21 (14.3%) of focal type lesions and 6/11(54.5%) of diffuse type lesions (p=0.035). Pre-procedural MLD was lower in the restenotic group compared to non-restenotic group (0.41 ± 0.29 vs. 0.64 ± 0.17 mm, p=0.048) while percent of stenosis was higher in the restenotic group (76.8 ± 12 vs. 69.6 ± 5.37%, p=0.029). CONCLUSION: In the selected patients, CBA is an effective and a safe method for the treatment of bare metal stent restenosis. CBA might be considered as a first-line treatment method in patients with focal type lesions.

OBJECTIVE: We aimed to investigate whether limb-salvage bypass operation improves outcomes in patients with critical infrapopliteal ischemia and poor or no distal arterial flow on angiography. METHODS: Forty-nine patients with severe tibial and peroneal occlusive disease and poor distal arterial flow on angiography were included in this prospective study. The age ranged from 57 to 82 years in the surgical group and 63 to 80 in the medical group. Patients had class III or IV disease according to Fontaine classification. Preoperative arterial Doppler ultrasonography and arteriography were performed in all patients. The ankle-brachial index (ABI) was calculated preoperatively and postoperatively in all of the cases. Twenty-three patients underwent distal bypass operation. Other 26 patients were followed with medical therapy. The outflow distal anastomoses were performed on posterior tibial, dorsal pedal, anterior tibial, peroneal, and lateral plantar arteries. All patients were followed-up for 3 years and clinical outcomes were recorded. The statistical analyses were performed using unpaired t, Mann Whitney and Wilcoxon tests. RESULTS: There were 3 early and 2 late graft failures. Limb salvage rates were 84.2%, 84.2%, 73.7% in the surgical group, and 82.8%, 69.9%, 64.3% in the medical group respectively in 6 months, 1 year, and 3 years. According to statistical analysis; the levels of the amputations tend to be lower in the surgical group than in the medical group but it was not significant statistically. Surgical treatment reduced the amputation ratio (p<0.05) but medical therapy did not (p>0.05). The difference between preoperative mean ABI [0.26+/-0.06] and postoperative mean ABI [0.80+/-0.24] was significant (p<0.05). CONCLUSION: We think that limb-salvage bypass operation may be preferred for patients with critical limb ischemia and poor distal flow on angiography. Infrapopliteal bypass will provide limb salvage and a functional extremity.

Pulmonary embolus and right atrial thrombus trapped in a patent foramen ovale is an unusual, rare condition. We report a case of impending paradoxical embolism with pulmonary embolism, in which a thrombus entrapped in a patent foramen ovale was detected. To our knowledge, this is the first case in the literature in which 'thrombus-in-transit' was detected in the right atrium both before and after entrapment in a patent foramen ovale.

BACKGROUND: Inflammation is one of the key mechanism in the development and progression of coronary artery disease. Myocardial bridging (MB) increases the tendency for development of atherosclerosis. The role of inflammation on the development of atherosclerosis in the MB is not clear. In this study, we investigated the existence of inflammation in the patients who have atherosclerotic plaque in the bridged segment. METHODS: This study included 40 patients (group I) presented with stable angina pectoris and detected MB in LAD on coronary angiography and 30 control subjects (group II) with normal coronary angiogram. Patients in group I were divided into two subgroups based on the findings on intravascular ultrasound (IVUS): group IA included 25 patients without atherosclerotic lesion in any coronary artery and group IB included 15 patients with atherosclerotic lesion in addition to MB in bridged segment of LAD. High-sensitivity C-reactive protein (hs-CRP) levels were compared between group I and II and group IA and IB. RESULTS: IVUS showed an atherosclerotic involvement with the proximal segment of MB in 15 patients (=group IB). No plaques were seen in other coronary arteries, in distal of MB or in the bridged segment. With regards to the level of hs-CRP, while no difference was established between group I and group II (1.7+/-0.4 mg/L vs 1.9+/-0.6 mg/L, p>0.05), hs-CRP was significantly higher in group IB than in group IA (3.2+/-0.3 mg/L vs 1.5+/-0.2 mg/L, p=0.001) and control group (3.2+/-0.3 mg/L vs 1.9+/-0.6 mg/L, p=0.03). A significant positive correlation was detected between the hs-CRP and the percentage of atherosclerotic stenosis on IVUS in group IB (R=0.639, p=0.01). CONCLUSIONS: These results indicate the presence of a low grade inflammation in patients with atherosclerotic lesion in bridged segment.

Traumatic aorto-right ventricular fistulas are rare lesions after penetrating thoracic injuries. Although aorto-right ventricular fistulas are well tolerated initially, most of them result in heart failure over a variable period. Penetrating cardiac trauma cases often need prompt cardiac surgery that does not allow further and detailed imaging methods for early diagnosis of lesions such as intracardiac defects and intracardiac fistulas. In this article, we report a case of aorto-right ventricular outflow tract fistula after a stab wound that was diagnosed on the second day after first successful surgery for acute tamponade.
