ABSTRACT
BACKGROUND: Double kissing (DK)-crush and T-stenting and small protrusion (TAP) techniques are gaining popularity, but the comparison for both techniques is still lacking. This study sought to retrospectively evaluate the long-term outcomes of DK-crush and TAP techniques in patients with complex bifurcation lesions. METHODS: A total of 255 (male: 205 [80.3%], mean age: 59.56 ± 10.13 years) patients who underwent coronary bifurcation intervention at a single-center between January 2014 and May 2021 were included. Angiographic features, procedure details, and in-hospital or long-term outcomes were assessed. The primary endpoint was target lesion failure (TLF), defined as the combination of cardiac death, target vessel myocardial infarction, or clinically driven-target lesion revascularization (TLR). The regression models were adjusted applying by the inverse probability weighted (IPW) approach to reduce treatment selection bias. RESULTS: The initial management strategy was DK-crush in 152 (59.6%) patients and TAP in 103 (40.4%) cases. The SYNTAX scores (24.58 ± 7.4 vs. 24.26 ± 6.39, p = 0.846) were similar in both groups. The number of balloon (6.32 ± 1.82 vs. 3.92 ± 1.19, p < 0.001) usage was significantly higher in the DK-crush group than in the TAP group. The rates of TLF (11.8 vs. 22.3%, p = 0.025) and clinically driven TLR (6.6 vs. 15.5%, p = 0.020) were significantly lower in the DK-crush group compared to the TAP group. The long-term TLF was significantly higher in the TAP group compared to the DK-crush group (unadjusted HR: 1.974, [95% CI: 1.044-3.732], p = 0.035 and adjusted HR [IPW]: 2.498 [95% CI: 1.232-5.061], p = 0.011). CONCLUSION: The present study showed that the DK-crush technique of bifurcation treatment was associated with lower long-term TLF and TLR rates compared to the TAP technique.

BACKGROUND: Double kissing crush (DKC) and nano-crush (NC) techniques are frequently used, but the comparison for both techniques is still lacking. The goal of this multicenter study was to retrospectively assess the midterm clinical results of DKC and NC stenting in patients with complex bifurcation lesions (CBLs). METHODS: A total of 324 consecutive patients [male: 245 (75.6%), mean age: 60.73 ± 10.21 years] who underwent bifurcation percutaneous coronary intervention between January 2019 and May 2023 were included. The primary endpoint defined as the major cardiovascular events (MACE) included cardiac death, target vessel myocardial infarction (TVMI), or clinically driven target lesion revascularization (TLR). Inverse probability weighting (IPW) was performed to reduce treatment selection bias. This is the first report comparing the clinical outcomes of DKC and NC stenting in patients with CBL. RESULTS: The initial revascularization strategy was DKC in 216 (66.7%) cases and NC in 108 (33.3%) patients. SYNTAX scores [25.5 ± 6.73 vs. 23.32 ± 6.22, p = 0.005] were notably higher in the NC group than the DKC group. The procedure time (76.98 ± 25.1 vs. 57.5 ± 22.99 min, p = 0.001) was notably higher in the DKC group. The incidence of MACE (18.5 vs. 9.7%, p = 0.025), clinically driven TLR (14.8 vs. 6%, p = 0.009), and TVMI (10.2 vs. 4.2%, p = 0.048) were notably higher in the NC group than in the DKC group. The midterm MACE rate in the overall population notably differed between the NC group and the DKC group (adjusted HR (IPW): 2.712, [95% CI: 1.407-5.228], p = 0.003). CONCLUSION: In patients with CBLs, applying the DKC technique for bifurcation treatment had better ischemia-driven outcomes than the NC technique.

BACKGROUND: This study aimed to evaluate the long-term outcomes of double kissing crush stenting (DKC) and mini-culotte technique (MCT) in patients with complex bifurcation lesions. METHODS: This retrospective study enrolled 236 patients who underwent percutaneous coronary intervention (PCI) for complex coronary bifurcation disease between January 2014 and November 2022. The primary endpoint was target lesion failure (TLF), defined as the combination of cardiac death, myocardial infarction (MI), or clinically driven target lesion revascularization (TLR). The secondary endpoint was major cardiovascular and cerebral events (MACCE) including all-cause death, MI, TLR, stroke, or stent thrombosis. The regression models were adjusted by applying the inverse probability weighted (IPW) approach to reduce treatment selection bias. RESULTS: The initial management strategy was DKC in 154 (65.3%) patients and MCT in 82 (34.7%) patients (male: 194 [82.2%], mean age: 60.85⯱ 10.86 years). The SYNTAX scores were similar in both groups. The rates of long-term TLF and MACCE rates were 17.4% and 20%, respectively. The rate of TLF (26.8% vs. 12.3%, pâ¯= 0.005) was higher in patients treated with MCT than those treated with the DKC technique, mainly driven by more frequent TLR (15.9% vs. 7.1%, pâ¯= 0.035). The long-term TLF and MACCE rates were notably lower in the DKC group compared to the others: adjusted hazard ratio (HR; IPW): 0.407, pâ¯= 0.009 for TLF, and adjusted HR(IPW): 0.391 [95% CI: 0.209-0.730], pâ¯= 0.003 for MACCE. CONCLUSION: At long-term follow-up, the rates of TLF and MACCE were 17.4% and 20%, respectively. However, long-term TLF was significantly higher in patients treated with MCT than those treated with the DKC technique, primarily due to a more frequent occurrence of clinically driven TLR.
ABSTRACT
Bicuspid aortic valve is the most common congenital cause for the development of aortic valve calcification and stenosis. Calcification cause valvular stenosis or valvular insufficiency due to coaptation failure. We report a unique case of calcification of bicuspid valve was extending to left ventricular outflow tract and attached to interventricular septum which caused subvalvular stenosis.

BACKGROUND AND AIM: There are conflicting results about the early administration of beta-blockers (bb) on in-hospital mortality and arrhythmias. Here, we wanted to investigate the effects of chronic bb use on in-hospital Atrial Fibrillation (AF) development in ST-Elevation Myocardial Infarction (STEMI) patients. MATERIALS AND METHODS: A total of 814 consecutive patients with STEMI were included in the study. They were divided into two groups according to whether they are using bb on admission or not. They were followed for AF development in-hospital and predictors of AF were determined by multivariable logistic regression analysis. RESULTS: Of the 814 patients, 103 (12.67%) patients were already using bb, while 711 (87.3%) were not. There were no significant differences in the frequency of AF development [3 (%2.9) vs 30 (%4.2), p = .788] between the groups. Multivariable logistic regression analysis showed that left atrial (LA) diameter is the only independent predictor of in-hospital AF development. CONCLUSIONS: Our study showed that chronic bb use does not have an effect on in-hospital AF development in STEMI patients. Nevertheless, LA diameter was found to be an independent predictor of AF.

BACKGROUND AND AIM OF THE STUDY: Transfusion-associated hyperpotassemia is a serious complication of packed red blood cell (PRBC) transfusion after congenital cardiac surgery. Our study aimed to identify risk factors and potential preventive measures of transfusion-associated hyperpotassemia in neonates and infants after congenital cardiac surgery. METHODS: Pediatric patients who underwent congenital cardiac surgery and need transfusion were enrolled in this prospective study. The potassium concentration of PRBC was checked from the sample taken from the segment. The volume of transfusion, age of PRBC, potassium concentration of unit were recorded. The estimated increment of potassium level in patients after PRBC transfusion was calculated. RESULTS: Seventy-four individual patients, 95 distinct transfusions, 112 blood products were evaluated. The mean age of the blood unit was 3.8 ± 1.4 days. The mean potassium concentration in the PRBCs was 9.9 ± 2.4 mmol/L. A weak correlation was observed between the potassium value of the PRBC and the age of PRBC (p = 0.049, r = 0.2, y = 0.24 × x + -0.68). There was a weak correlation between the potassium value of PRBCs and the age of the unit (p < 0.001, r = 0.37, y = 2.8 × x + -3.6). CONCLUSIONS: Before transfusion, even PRBC is fresh, measuring the potassium level of PRBC and the potassium that will be given to the pediatric patient with transfusion can prevent transfusion-related hyperpotassemia and related complications. Otherwise, high potassium levels, which may be overlooked despite being fresh, may cause serious complications, even cardiac arrest, especially in neonates and infants.

BACKGROUND AND AIM OF THE STUDY: After congenital cardiac surgery, the duration of mechanical ventilation (MV) is related to the clinical status, type of operation, and the sedative-analgesic agents used postoperatively. This study aims to examine the effects of dexmedetomidine and morphine on the fast-track extubation (FTE) and ultra-fast-track extubation (UFTE) protocol after congenital cardiac surgery. METHODS: A total of 251 pediatric patients were divided into two groups: 118 patients in the morphine group (Group M) and 133 patients in the dexmedetomidine group (Group D). We retrospectively reviewed medical data including hemodynamic parameters, duration of MV and cardiovascular intensive care unit (CICU), additional sedative/analgesic requirement, adverse events, the need for reintubation, and noninvasive MV, sedation, and pain scores. RESULTS: The mean mechanical ventilation duration of Group D was significantly shorter than Group M (3.74 ± 0.83 h in Group D, 5.72 ± 1.54 h in Group M, respectively) (p = .001; p < .05). In Group D, the success rate of FTE was 92.5% (n = 123) and UFTE was 7.5% (n = 10) (p = .001). In Group M, the success rate of FTE was 72.9% (n = 86) and UFTE was 0% (n = 0) (p > .05). CONCLUSIONS: Dexmedetomidine and morphine have clinical benefits which encourage their use for FTE protocol. Dexmedetomidine has more benefits compared to morphine. It can be used in UFTE protocol, besides its use in FTE protocol with fewer side effects.

Sternal closure can lead to hemodynamic and respiratory instability after some complex pediatric cardiac surgeries. In such cases, delayed sternal closure is applied to facilitate postoperative recovery. During open sternum several instruments have been defined to prevent the sternum from compressing the heart; however, most of them have limitations. We, therefore, have attempted to use a new instrument to keep the sternum open in neonates and infants. This instrument has been used as an adult eye speculum which is made of a flexible metal wire. It is delicate, ready to use, easily placed, and good fitted to the pediatric sternal edges.

BACKGROUND: Limited data exist regarding the coronary revascularization procedures needed during the repair of several congenital and pediatric cardiac malformations. We aimed to determine risk factors for in-hospital mortality and long-term outcomes of various pediatric coronary revascularization procedures. METHODS: We retrospectively reviewed the records of 32 consecutive pediatric patients who underwent coronary revascularization procedures at our institution between May 1995 and June 2020. In-hospital mortality, risk factors, surgical indications, revascularization patency, and mid- and long-term follow-up data were investigated. Patients were categorized into the coronary artery bypass grafting (n = 11) and other coronary artery procedure (n = 21) groups. RESULTS: The median age and weight of patients at the time of surgery were 9 months and 4.8 kg, respectively. There were five in-hospital deaths (5/32, 15.6%). The mortality rates were 27.2% (3/11) in the coronary artery bypass grafting group and 9.5% (2/21) in the other coronary artery procedure group (p = .206; 95% confidence interval: 0.496-25.563). The mortality rates for planned and rescue procedures were 8.3% (2/24) and 37.5% (3/8) (p = .06), respectively. The median follow-up time was 12.5 years. Control imaging studies for coronary patency were performed in 70.3% (19/27) of surviving patients. The overall coronary patency rate was 94.7% (18/19). CONCLUSIONS: Pediatric coronary revascularization procedures with elective-planned indications can be performed with good outcomes. Young age and rescue and emergency procedures may carry an increased risk of in-hospital mortality, although not found to be statistically significant. Surviving patients require lifelong follow-up regarding the patency of reperfused coronary arteries.

BACKGROUND: Postoperative thoracic aortic graft infection (TAGI) is a serious and potentially fatal complication. The classical approach is to replace the infected graft. However, this approach has a high mortality rate. Alternatively, treatment of TAGI without graft replacement can be performed METHOD: Herein, we present a 72-year-old case with mediastinitis and graft infection after type A aortic dissection operation and successful treatment using omental flap coverage following vacuum-assisted wound closure therapy without graft replacement. CONCLUSION: The patient had an uneventful postoperative course and remains infection-free to date.

Background and aim: In patients undergoing congenital cardiac surgery, it is crucial to maintain oxygen demand-consumption balance. Central venous oxygen saturation (ScvO2) is a useful indicator of oxygen demand and consumption balance which is an invasive method. Near-infrared spectroscopy (NIRS) is a noninvasive, continuous monitoring technique that measures regional tissue oxygenation. NIRS that is placed over the internal jugular vein cutaneous area (NIRSijv) has the potential to show ScvO2 indirectly. In this study, we aimed to determine the correlation between ScvO2 with NIRSijv in pediatric patients undergoing congenital cardiac surgery. Materials and methods: Fifty children participated in the study. Four patients were excluded for the inability of internal jugular vein (IJV) catheterization due to technical difficulties. After anesthesia induction, NIRS probes were placed on the IJV site with ultrasound guidance for the measurement of continuous transcutaneous oxygen saturation. The catheter insertion was also done through the IJV from the other side using ultrasound guidance. Cerebral oxygenation monitoring was done using NIRS with a single pediatric probe placed on the right forehead. Values of NIRSijv, cerebral NIRS (NIRSc) and ScvO2, were recorded at certain times until postoperative 24th hour. Results: Data were collected at 8 different time points. There was a significant correlation between ScvO2 and NIRSijv in all measurement time points (r = 0.91), (P = 0.001). The mean bias between ScvO2 and NIRSijv was 2.92% and the limits of agreement were from 11% to 5.2%. There was a moderate correlation between ScvO2 and NIRSc (r = 0.45), (P = 0.001). The mean bias between ScvO2 and NIRSc was 2.7% and the limits of agreement were from +26% to 20%. Conclusions: In this study, we found a strong correlation between ScvO2 and NIRS measurements taken from the internal jugular vein site. Accordingly, continuous noninvasive monitoring with transcutaneous NIRSijv can be an alternative method as a trend monitor for the central venous oxygen saturation in pediatric cardiac patients undergoing congenital cardiac surgery.

Pulmonary valve preservation in tetralogy of Fallot (TOF) repair is one of the most challenging issues. Herein, we describe a novel valve-sparing technique for TOF repair that primarily consists of skeletonization of the anterior part of the pulmonary annulus and gentle dilatation by preserving the pulmonary valve and annulus integrity. With encouraging early results, this technique is suggested to prevent severe pulmonary regurgitation and provide acceptable relief of pulmonary stenosis in patients with TOF.

BACKGROUND: Acute pulmonary embolism (PE) is a serious clinical disease characterized by a high mortality rate. The aim of this study was to assess the prognostic value of international normalized ratio (INR) in acute PE patients not on anticoagulant therapy. METHODS: The study included 244 hospitalized acute PE patients who were not receiving previous anticoagulant therapy. Based on their 30-day mortality, patients were categorized as survivors or non-survivors. INR was measured during the patients' admission, on the same day as the diagnosis of PE but before anticoagulation started. RESULTS: Thirty-day mortality occurred in 39 patients (16%). INR was higher in non-survivors than in survivors (1.3±0.4 vs 1.1±0.3, P=.003). In multivariate analysis, INR (HR: 3.303, 95% CI: 1.210-9.016, P=.020) was independently associated with 30-day mortality from PE. Inclusion of INR in a model with simplified pulmonary embolism severity index (sPESI) score improved the area under the receiver operating characteristics (ROC) curve from 0.736 (95% CI: 0.659-0.814) to 0.775 (95% CI: 0.701-0.849) (P=.028). Also, the addition of INR to sPESI score enhanced the net reclassification improvement (NRI=8.8%, P<.001) and integrated discrimination improvement (IDI=0.043, P=.027). CONCLUSION: Elevated INR may have prognostic value for 30-day mortality in acute PE patients not on anticoagulation. Combining INR with sPESI score improved the predictive value for all-cause mortality. However, further large-scale studies are needed to confirm it's prognostic role.

Objectives Vascular endothelial dysfunction leads to the emerging of free oxygen radicals, deficiency of antioxidant system, forming of oxidative stress, inflammatory processes and release of proinflammatory cytokines. These things play big role in the development of primary varicose veins. Prolidase has been reported as an indicator of oxidative stress in diabetes, diabetic neuropathy, non-ulcerous dyspepsia, osteoporosis, polycystic over syndrome and many other diseases. The aim of this study is to evaluate the oxidative stress at venous insufficiency and to provide preliminary knowledge about the role of prolidase enzyme in varicose vein formation. Methods Ninety patients aged between 22 and 80 (47.35 ± 17.69) were included in the study and divided into 3 groups. Group1(n:30)(Serum control group): Patients without venous insufficiency. Group 2(n:30)(Tissue control group(healthy vein group): Patients underwent coronary artery bypass surgery (the remaining portion of great saphenous vein used as coronary artery bypass graft used as normal tissue) . Group 3(n:30)(Varicose vein group): Patients underwent varicose vein surgery (varicose vein and serum of these patients were used for study). Total Oxidant Status (TOS), Total Antioxidant Status (TAS), Oxidative Stress Index (OSI) and Prolidase enzyme levels were detected in tissue and serum samples. Results No significant changes were detected between three groups' serum samples in oxidative stress parameters and in the prolidase enzyme activity. The tissue TOS and OSI were higher in varicose vein group according to normal vein group and this was found statistically significant. And TAC levels in varicose vein group were significantly lower than normal vein group. Prolidase enzyme activity in varicose vein group was found higher according to normal vein group. Conclusion Oxidative stress plays a role at the development of primary varicose veins at biochemical level. Prolidase enzyme related with oxidative stress may play an important role in the pathogenesis of primary varicose veins.

Background/aim: Although pulmonary valve replacement (PVR) improves ventricular function and symptoms, the benefit and optimal timing of PVR are controversial. This study aimed to evaluate early response to PVR for right ventricle (RV) dilatation and QRS duration. Materials and methods: Retrospective analysis was performed for 32 patients with repaired tetralogy of Fallot (TOF) between March 2005 and October 2017. The differences between preoperative and postoperative changes in echocardiographic parameters, clinical symptoms, and QRS duration were evaluated. Results: There were no in-hospital or late deaths. Mean age at the time of PVR was 16.57 ± 7.97 years. The interval between TOF repair and PVR was 12.99 ± 7.06 years. Postoperative echocardiographic findings showed significant reduction in indexed RV end-diastolic diameter (RV-EDDI) and the ratio of RV/LV-EDDI (P = 0.001 and P = 0.001, respectively). Higher preoperative RV-EDDI was associated with decreased change in RV-EDDI after PVR (r = 0.63; P = 0.001). Normalization of RV diameters was found to be independent of age at PVR, interval between TOF repair and PVR, preoperative QRS duration, and preoperative RV-EDDI. Conclusion: Significant improvement in RV diameter and symptoms could be obtained with PVR in patients with severe pulmonary regurgitation.
ABSTRACT
BACKGROUND Hypothyroid has several effects on the cardiovascular system. Global myocardial performance index (MPI) is used in assessment of both left ventricular (LV) systolic and diastolic function. We compared MPI in hypothyroidism patients vs. normal control subjects. MATERIAL AND METHODS Eighty-two hypothyroid patients were divided into 2 groups: a subclinical hypothyroid (SH) group (n=50), and an overt hypothyroid (OH) group (n=32). The healthy control group (CG) constituted of 37 patients. TSH, FT3, and FT4, anti-TPO, anti-TG, insulin, lipid values, and fasting glucose levels were studied. All patients underwent an echocardiographic examination. Myocardial performance indexes were assessed and standard echocardiographic examinations were investigated. RESULTS MPI averages in OH, SH, and control groups were 0.53±0.06, 0.51±0.05, and 0.44±0.75 mm, respectively. MPI was increased in the OH and SH groups in comparison to CG (p<0.001, p<0.001, respectively). CONCLUSIONS MPI value was significantly higher in hypothyroid patients in comparison to the control group, showing that regression in global left ventricular functions is an important echocardiographic finding. Future studies are required to determine the effects of this finding on long-term cardiovascular outcomes.

Atrial fibrillation (AF) is the most common supraventricular arrhythmia following ST elevation myocardial infarction (STEMI). Oxidative stress and inflammation may cause structural and electrical remodeling in the atria making these critical processes in the pathology of AF. In this study, we aimed to evaluate the association between total oxidative status (TOS), total antioxidative capacity (TAC) and high-sensitivity C-reactive protein (hs-CRP) in the development of AF in patients presenting with STEMI. This prospective cohort study consisted of 346 patients with STEMI. Serum TAC and TOS were assessed by Erel's method. Patients were divided into two groups: those with and those without AF. Predictors of AF were determined by multivariate regression analysis. In the present study, 9.5% of patients developed AF. In the patients with AF, plasma TOS and oxidative stress index (OSI) values were significantly higher and plasma TAC levels were significantly lower compared to those without AF (p = .003, p = .002, p < .0001, respectively). Multivariate regression analysis results showed that, female gender (Odds ratio [OR] = 3.07; 95% Confidence Interval [CI] = 1.26-7.47; p = .01), left atrial diameter (OR =1.28; 95% CI =1.12-1.47; p < .0001), hs-CRP (OR =1.02; 95% CI =1.00-1.03; p = .001) and OSI (OR =1.10; 95% CI =1.04-1.18; p = .001) were associated with the development of AF in patients presenting with STEMI. The main finding of this study is that oxidative stress and inflammation parameters were associated with the development of AF in patients presenting with STEMI. Other independent predictors of AF were female gender, left atrial diameter and hs-CRP.

Background Pulmonary embolism (PE) is a common and life-threatening condition associated with considerable morbidity and mortality. Pleural effusion occurs in about one in three cases; however, data on its prognostic value are scarce. Purpose To investigate the association between pleural effusion and both 30-day and long-term mortality in patients with acute PE. Material and Methods We retrospectively evaluated 463 patients diagnosed with acute PE using computed tomography pulmonary angiography (CTPA). Echocardiographic, demographic, and laboratory data were collected. The study population was divided into two groups: patients with and without pleural effusions. Pleural effusion detected on CT was graded as small, moderate, and large according to the amount of effusion. The predictors of 30-day and long-term total mortality were analyzed. Results Pleural effusions were found in 120 patients (25.9%). After the 30-day follow-up, all-cause mortality was higher in acute PE patients with pleural effusions than in those without (23% versus 9%, P < 0.001). Also, patients with pleural effusions had significantly higher incidence of long-term total mortality than those without pleural effusions (55% versus 23%, P < 0.001). In a multivariate analysis, pleural effusion was an independent predictor of 30-day and long-term mortality (odds ratio [OR], 2.154; 95% confidence interval [CI], 1.186-3.913; P = 0.012 and OR, 1.591; 95% CI, 1.129-2.243; P = 0.008, respectively). Conclusion Pleural effusion can be independently associated with both 30-day and long-term mortality in patients with acute PE.

OBJECTIVE: The aim of this study was to evaluate the efficacy of nebivolol, carvedilol or metoprolol succinate on the outcome of patients presenting with acute myocardial infarction (AMI) complicated by left ventricular dysfunction. SUBJECTS AND METHODS: Patients (n = 172, aged 28-87 years) with AMI and left ventricular ejection fraction ≤0.45 were randomized to the nebivolol (n = 55), carvedilol (n = 60) and metoprolol succinate (n = 57) groups. Baseline demographic and clinical characteristics and composite event rates of nonfatal MI, cardiovascular mortality, hospitalization due to unstable angina pectoris or heart failure, stroke or revascularization during the 12-month follow-up were compared among the groups using the x03C7;2 test, t test or log-rank test as appropriate. RESULTS: Baseline demographic and clinical characteristics were similar in the three groups. The composite end point during follow-up was lower in the patients treated with nebivolol than those treated with metoprolol (14.5 vs. 31.5%; p = 0.03). However, event rates were similar between the patients treated with carvedilol and those treated with the metoprolol (20.3 vs. 31.5%, p > 0.05) and between the patients treated with nebivolol and carvedilol (14.5 vs. 20.3%, p > 0.05). CONCLUSION: The patients treated with nebivolol experienced 12-month cardiovascular events at a lower rate than those treated with metoprolol succinate. However, event rates were similar between the carvedilol and the metoprolol succinate groups and between the nebivolol and the carvedilol groups.
