Objective: This study aims to evaluate outcomes in nutcracker syndrome patients with tolerable symptoms and treated conservatively without invasive interventions., Methods: This prospective study included patients treated conservatively. Promoting weight gain, the endpoint of the study was spontaneous resolution of symptoms., Results: Sixteen patients (75% female and mean age 24.4 ± 3.5 years) underwent conservative management. Over a mean follow-up of 27.3 months [13-42, interquartile range (IQR)], the diameter ratio (5.5 [5-6.5, IQR] vs 4.3 [4.1-6], p = NS), the peak velocity ratio (6 [5-7, IQR] vs 4.8 [4.8-5.8], p = NS), beak angle (27° [24-30, IQR] vs 29° [24-32]; p = NS), and aortomesenteric angle (26° [23-29, IQR] vs 28° [24-30]; p = NS) exhibited no statistically significant changes. Complete resolution and improvement of symptoms were 28.5% and 31.4%, respectively, while 68.5% remained unchanged., Conclusions: This study shows that a conservative approach contributes to the spontaneous improvement or complete resolution in young adult patients with mild symptoms., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Coverage of the left subclavian artery origin is required to achieve adequate proximal seal during up to 40% of TEVAR cases. The evidence regarding left subclavian artery revascularization in patients undergoing elective or emergent TEVAR with left subclavian artery coverage is weak, and there is ongoing debate whether revascularization should be performed routinely of selectively. Beyond this debate, there is a lack of data about left subclavian artery coverage during TEVAR in end-stage renal disease patients with a functional left upper limb atreriovenous fistula. We present the case of a patient with a left distal radiocephalic arteriovenous fistula who underwent emergent TEVAR with left subclavian artery coverage for ruptured type B aortic dissection. The arteriovenous fistula remains functional on a 3-month follow-up, and the patient did not develop symptoms related to posterior stroke, spinal cord ischemia, limb ischemia, or vertebrobasilar insufficiency., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objectives: Our study was conducted to determine the effects of intraoperative antithymocyte globulin administration on donor hearts procured after cardiocirculatory death. We evaluated the impact of antithymocyte globulin on graft function and related parameters during isothermic blood cardioplegia., Materials and Methods: In this prospective and randomized single center study, 30 patients with orthotropic heart transplant were divided into 2 groups: group 1 included 15 patients who received retrograde antithymocyte globulin infusion via coronary sinus intraoperatively and immediately after organ procurement and group 2 included 15 patients who received traditional antithymocyte globulin infusion after implantation., Results: Study patients had a mean age of 33.8 years (range, 15-56 y). All patients had panel reactive antibody less than 10% except for 3 patients. The cluster of differentiation 3-positive cell count decrease was more than 20%. The inotropic therapy dose required and the myocardial pressure (stiffness) were less for group 1 patients. These patients had less acute rejection episodes than group 2 (0% vs 13.3%; P < .05)., Conclusions: Favorable clinical outcomes were observed in terms of less acute rejection episodes and better graft function at least during the early posttransplant period. Intraoperative antithymocyte globulin treatment may have a preventive effect for acute cellular rejection in heart transplant patients.

Background: This study aims to investigate the association of progression of tricuspid regurgitation following double-valve replacement by comparing the tricuspid valve repair and no repair groups, and to analyze outcomes of patients with non-repaired mild-to-moderate tricuspid regurgitation., Methods: Between January 2014 and September 2017, a total of 157 patients (74 males, 83 females; mean age: 51.7±13.7 years; range, 18 to 78 years) who underwent aortic and mitral valve replacements with/without concomitant tricuspid valve repair were retrospectively analyzed. The patients were divided into two groups: no-repair (n=78) and repair groups (n=79). The primary outcome measure was development of more than moderate tricuspid regurgitation during follow-up., Results: The data were evaluated according to propensity score matched analysis. The progression of tricuspid regurgitation was significantly increased in the no-repair group (p=0.006). Rheumatic etiology was independently associated with the presence of postoperative moderateto- severe tricuspid regurgitation (p=0.004, odds ratio: 3.40). There was no statistically significant difference between the groups in terms of the potential complications and mortality and survival rates. A multivariable subgroup analysis for the baseline mild-to-moderate tricuspid regurgitation without repair showed that rheumatic etiology was an independent factor for the progression of postoperative tricuspid regurgitation (p=0.01)., Conclusion: Our study results demonstrated that rheumatic etiology was an independent marker for increased tricuspid regurgitation and it was also independently associated with increased tricuspid regurgitation in patients with mild-to-moderate non-repaired patients. The degree of tricuspid regurgitation was improved in the repair group during follow-up., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article., (Copyright © 2022, Turkish Society of Cardiovascular Surgery.)

Introduction: In this trial, we initially aimed to investigate the major predictive factors for prolonged mechanical ventilation (PMV) following cardiac surgery with cardiopulmonary bypass (CPB) in our center and, secondarily, we tried to find out the effects of the independent factors on mortality., Methods: Between July 2017 and August 2018, 207 patients who underwent cardiac surgery with CPB were retrospectively investigated. The patients were randomly divided into two subgroups according to the duration of ventilator dependence (group 1 <24 hours, n=164, 79%; group 2 >24 hours, n=43, 21%)., Results: 207 patients (mean age 59.47±10.56) who underwent cardiac surgery with CPB were enrolled in this study (n=145, 70% of male patients; n=62, 30% of female patients). Amid these patients, 43 (n=43, 20.77%) had prolonged intubation time. After multivariate logistic regression analysis among preoperative factors, female gender (OR=2.321, P=0.028), leukocytosis (OR=1.233, P=0.006), perioperative lactate level (OR=1.224, P=0.027), CPB time (OR=1.012, P=0.012) and postoperative revision for bleeding (OR=23.125, P=0.040) were significantly detected. The effect of predictive factors on mortality after cardiac surgery was determined and found that PMV did not affect hospital mortality (OR=1.979, P=0.420)., Conclusion: In our report, we revealed, differently from previous studies, that intraoperative lactate levels which manifest organ perfusion and oxygenation were included and were significantly different in the early extubation group compared to the PMV group. Female gender, preoperative leukocytosis, intraoperative CPB time, lactate levels and postoperative revision for bleeding were the independent predictive factors for PMV. Moreover, PMV did not affect the early-term mortality during hospital stay.

Cardiac myxomas (CM) is by far the most common type of primary cardiac neoplasm that commonly arise within the left atria and is composed of primitive connective tissue cells and stroma. Despite the benign nature, the CMs are often surgically removed because they can lead to severe complications. Large, thin, and hypermobile forms are unusual. The frequency of recurrence is about 22% for complex forms and 12% for other familial forms and 1% to 3% for sporadic myxomas, which seldom recur after surgery. Although transesophageal echocardiography shows usually accurate imaging capabilities to detect the myxoma, further imaging methods including computed tomography, cardiovascular magnetic resonance imaging, and 18 F-fluorodeoxyglucose positron-emission tomography/computed tomography may be useful to diagnosis for it. Surgery is the mainstay of treatment., (© 2019 Wiley Periodicals, Inc.)

Objective: Acute kidney injury (AKI) is one of the most important complications after coronary artery bypass grafting (CABG) procedure. Serum albumin, which is an acute phase reactant, is suggested to be associated with AKI development subsequent to various surgical procedures. In this study, we research the relation between preoperative serum albumin levels and postoperative AKI development in diabetes mellitus (DM) patients undergoing isolated CABG., Methods: We included a total of 634 diabetic patients undergoing CABG (60.5±9.1 years, 65.1% male) into this study, which was performed between September 2009 and January 2014 in a single center. The relation between preoperative serum albumin levels and postoperative AKI development was observed. AKI was evaluated and diagnosed using the Kidney Disease: Improving Global Outcomes (KDIGO) classification., Results: AKI was diagnosed in 230 (36.3%) patients. Multiple logistic regression analysis was performed to determine the independent predictors of AKI development. Proteinuria (odds ratio [OR] and 95% confidence interval [CI], 1.066 [1.002-1.135]; P=0.043) and low preoperative serum albumin levels (OR and 95% CI, 0.453 [0.216-0.947]; P=0.035) were found to be independent predictors of AKI. According to the receiver operating characteristic curve analysis, albumin level <3mg/dL (area under the curve: 0.621 [0.572-0.669], P<0.001) had 83% sensitivity and 10% specificity on predicting the development of AKI., Conclusion: We observed that a preoperative low serum albumin level was associated with postoperative AKI development in patients with DM who underwent isolated CABG procedure. We emphasize that this adjustable albumin level should be considered before the operation since it is an easy and clinically implementable management for the prevention of AKI development.

Introduction: The mechanical circulation support used in treatment of low cardiac output at most is the intra-aortic balloon pump (IABP). Its usage fields are the complications occurring due to ischemic heart disease, disrupted left ventricle function, and the low cardiac output syndrome occurring during coronary artery by-pass surgery. Methods: During 28 years from 1985 to 2013, IABP support has been implemented to 3135 patients in our cardiac surgery operating theater and intensive care unit. The mean age of the patients was 61.4 ± 13.2 years (16-82). 2506 patients (80%) were the ones whom the cardiac surgery has been implemented. IABP support has been provided for 629 (20%) patients for medical treatment. We utilized IABP most frequently in coronary artery patients (70%). The first choice for placing the balloon catheter is the femoral artery in 3093 cases (98.7%). Results: The most frequently observed balloon complication was the lower extremity ischemia in 383 cases (12.2%).The leg ischemia was statistically significantly more frequent in patients with sheath (P=0.004). The extremity ischemia has developed in 4 of 12 patients with balloon placed from upper extremity. The local bleeding and balloon rupture were more frequent in patients whom the balloon has been placed without sheath. The mortality due to IABP has occurred in only 5 patients. Conclusion: Despite increase in IABP usage frequency rapidly, the complications due to catheter are still seen. We believe that the leg ischemia that is the most frequently seen complication can be prevented via IABP use without sheath.

Totally endoscopic robotic surgery is a safe approach to atrial septal defect closure in adults. Robotic approach can be an alternative to traditional incisions in the management of concomitant tricuspid valve regurgitation with ruptured chordae tendineae. Herein, we describe a woman who presented with atrial septal defect and tricuspid insufficiency after an unsuccessful percutaneous intervention with device removal from the right ventricle. Concomitant closure of septal defect and tricuspid valve repair with artificial chords was successfully performed using robot assistance.

Aim: We undertook genetic assessment of coronary artery disease (CAD) in 20 patients aged 30 years or less undergoing coronary artery bypass grafting (CABG) surgery, to investigate the prognostic value of pre-defined genes., Methods: Twenty patients, who underwent CABG surgery between December 2001 and May 2013, were retrospectively analysed to find out the role their genetic make-up played in their disease. We used three genetic diagnostic tests, the plasminogen activator inhibitor (PAI) -1 gene, the A1/A2 polymorphism of glycoprotein IIIa (GpIIIa) gene, and common polymorphisms of the methylenetetrahydrofolate reductase (MTHFR) gene., Results: The mean age of patients was 26.35 ± 3.51 (19-30) years, and 90% were male (n = 18). One patient had diabetes, three had hypertension, 11 (55%) had dyslipidaemia and 16 (80%) were smokers. Eight of the patients (40%) had left ventricular ejection fraction (LVEF) < 50%, and functional capacity was poor in only two (10%) patients (NYHA III-IV). Follow up was completed in all patients (100%). We found five homozygous and 11 heterozygous mutations in the MTHFR gene, which predisposes individuals to coronary artery disease or deep-vein thrombosis. Eight patients were found to have a GpIIIa gene polymorphism, which is associated with increased risk of myocardial infarction (MI). Fifteen patients had a polymorphism in the promoter region of the PAI-1 gene, which is a major inhibitor of the fibrinolytic system., Conclusion: MTHFR C677T polymorphism, and GpIIIa and PAI-1 genes are risk factors for CAD. In young patients, genetic studies promise to revolutionise early diagnosis, treatment and prevention of CAD and MI.

Background: Due to ventricular compensatory mechanisms, patients with severe aortic regurgitation are generally asymptomatic. Severe left ventricular dysfunction develops annually in 20% of non-operated cases, and the prognosis in those cases is poor. Although surgery is recommend in patients with left ventricular dysfunction, surgeons are wary. We investigated the changes in ventricular and effort capacity after surgery in patients with normal and abnormal left ventricular function., Methods: We retrospectively examined the data of patients with aortic regurgitation who underwent aortic valve replacement in our clinic between 1993 and 2013. Those who had previous cardiac surgery, chemotherapy, radiotherapy, renal dysfunction, diabetes mellitus, or preoperative arrhythmias were excluded. The 113 patients were divided into 2 groups according to ejection fraction., Results: In patients with ejection fraction <50%, interventricular septal thickness, posterior wall thickness, and left ventricular mass were significantly greater than in the ejection fraction ≥50% group (p < 0.01). No significant differences in intensive care unit stay and hospitalization were determined. No mortality was observed. Ejection fraction and effort capacity increased significantly after aortic valve replacement in both groups, and interventricular septal thickness, posterior wall thickness, and left ventricular mass decreased in both groups., Conclusions: Significant left ventricular functional improvements can be achieved after aortic valve replacement in patients with severe aortic regurgitation who develop left ventricular dysfunction. Despite the reported higher surgical mortality in this patient group, surgical treatment offers a survival benefit. We recommend surgical treatment in patients with severe aortic regurgitation who develop left ventricular dysfunction., (© The Author(s) 2016.)

Aortic root abscess is the most severe sequela of infective endocarditis, and its surgical management is a complicated procedure because of the high risk of morbidity and death. Twenty-seven patients were included in this 15-year retrospective study: 21 (77.8%) with native- and 6 (22.2%) with prosthetic-valve endocarditis. The surgical reconstruction of the aortic root consisted of aortic valve replacement in 19 patients (70.4%) with (11) or without (8) a pericardial patch, or total aortic root replacement in 7 patients (25.9%); 5 of the 27 (18.5%) underwent the modified Bentall procedure with the flanged conduit. Only one patient (3.7%) underwent subaortic pericardial patch reconstruction without valve replacement. A total of 7 patients (25.9%) underwent reoperation: 6 with prior valve surgery, and 1 with prior isolated sinus of Valsalva repair. The mean follow-up period was 6.8 ± 3.7 years. There were 6 (22.2%) in-hospital deaths, 3 (11.1%) of which were perioperative, among patients who underwent emergent surgery. Five patients (23.8%) died during follow-up, and the overall survival rates at 1, 5, and 10 years were 70.3% ± 5.8%, 62.9% ± 6.4%, and 59.2% ± 7.2%, respectively. Two of 21 patients (9.5%) underwent reoperation because of paravalvular leakage and early recurrence of infection during follow-up. After complete resection of the perianular abscess, replacement of the aortic root can be implemented for reconstruction of the aortic root, with or without left ventricular outflow tract injuries. Replacing the aortic root with a flanged composite graft might provide the best anatomic fit.

Study Objective: To compare adhesion formation and histological features of peritoneal closure and nonclosure over an intra-abdominally placed barbed suture., Design: Single-blind randomized controlled trial (Canadian Task Force Classification I)., Setting: Certified animal research facility., Subjects: Eight nonpregnant rats., Interventions: Abdominal cavities were entered via midline incision. Left and right parietal peritoneal surfaces were incised 1.5 cm long separately and stitched with unidirectional barbed suture material (3/0 V-Loc). The parietal peritoneum was approximated over the barbed suture using polypropylene suture material (7/0 Prolene) to embed the barbed suture (peritonization) on one side, and left open on the other side. The side of the barbed suture to be peritonized was allocated at random. On the postoperative day 32, all rats were sacrificed, adhesion formations on each side were macroscopically scored, and histological features were evaluated microscopically., Measurement and Main Results: The median adhesion score was 2.00 (range, 1-4) on operative fields. There was no statistically significant difference in median adhesion score between the peritonized and nonperitonized sides (1.5 vs 2, respectively; p = .13). Microscopically, there were no statistically significant differences in median acute and chronic inflammation scores between the peritonized and nonperitonized sides (p = .58 and p = .45, respectively), but a significantly higher median fibrosis score on the peritonized side (3 vs 1.5, respectively; p = .02)., Conclusion: Based on the results of the present study in a rat model, barbed suture material might be associated with adhesion formation when used intra-abdominally, and these adhesions could not be prevented by peritonization., (Copyright © 2015 AAGL.

Purpose: We sought to determine whether hypothermia provided any benefit in patients undergoing simultaneous coronary artery bypass graft surgery (CABG) and carotid endarterectomy (CEA) using one of two different surgical strategies., Methods: Group 1 patients (n = 34, 88.2% male, mean age 65.94 ± 6.67 years) underwent CEA under moderate hypothermia before cross clamping the aorta, whereas group 2 patients (n = 23, 69.6% male, mean age 65.78 ± 9.29 years) underwent CEA under normothermic conditions before initiating cardiopulmonary bypass (CPB). Primary outcome of interest was the occurrence of any new neurological event., Results: The two groups were similar in terms of baseline characteristics. Permanent impairment occurred in one patient (2.9%) in group 1. One patient from each group (2.9 and 4.37%) had transient neurological events and they recovered completely on the sixth and 11th postoperative days, respectively. Overall, there was no statistically significant difference between the two groups with regard to occurrence of early neurological outcomes (n = 2, 5.8 % vs n = 1, 4.3 %, p = 0.12)., Conclusions: This study could not provide evidence regarding benefit of hypothermia in simultaneous operations for carotid and coronary artery disease because of the low occurrence rate of adverse outcomes. The single-stage operation is safe and completion of the CEA before CPB may be considered when short duration of CPB is required.

Ectopic thyroid tissue is a result of abnormal migration of thyroid tissue during the embryonic state. Most of these rare cases, almost 90% of them, are located in the base of the tongue and a minority of them is located anteriorly near the hyoid bone area. Below we report the case of a young patient with an intracardiac mass first diagnosed with three-dimensional echocardiography and afterward successfully treated surgically. Once a careful histological examination has revealed a follicular adenoma, the prognosis is good especially if successful surgical excision is part of the management., (© 2014, Wiley Periodicals, Inc.)

Context: Patients with chronic renal failure have a high prevalence of coronary artery disease and cardiovascular death. The mortality and the morbidity rates of cardiac surgery are particularly high in these patients with end-stage renal disease. Performing cardiac surgery and kidney transplant in the same session can reduce these complications in the early postoperative period by normalizing renal function., Objective: To compare the mortality and morbidity rates between patients who had undergone cardiac surgery and kidney transplant separately and patients who had combined surgeries., Methods: This retrospective study consisted of 75 patients. One group of 60 patients underwent cardiac surgery and kidney transplant in separate sessions, and the other group of 15 patients had combined surgeries in the same session, between March 2008 and September 2012., Results: Patients who had combined surgeries achieved fluid electrolytic balance more easily, had shorter extubation times, used less blood and blood products, and had fewer major complications. The patients recovered faster and thus had shorter stays in the intensive care unit and hospital. This combined surgical approach allows normalized kidney function in patients with end-stage renal disease, so mortality and morbidity in the early postoperative period could be significantly reduced.
