ABSTRACT

Background: This study aims to investigate the dilation of sinus valsalva in patients who underwent aortic repair due to type A aortic dissection and to evaluate its progression. Methods: Between January 2004 and December 2019, a total of 68 patients (50 males, 18 females; mean age: 54.2±10.1 years; range, 30 to 82 years) who underwent root-preserving surgery and followed for at least one year in the outpatient setting were retrospectively analyzed. The patients were divided into two groups according to dilatation during follow-up. Group 1 (n=32) included patients with dilatation and Group 2 (n=36) included patients without dilatation. The sinus of Valsalva diameters were measured using pre- and postoperative computed tomography angiography. Results: The mean follow-up was 4.9±3.1 (range, 1 to 4) years. Sinus of Valsalva dilatation was observed in 47% of the patients during follow-up. Preoperative sinus of Valsalva diameter was a risk factor for aneurysmatic dilatation. A diameter of ≥4.05 cm was calculated as a cut-off value for developing dilatation requiring reoperation. Conclusion: Follow-up using postoperative echocardiography or computed tomography angiography is of utmost importance for the assessment of development of sinus of Valsalva dilatation which requires reoperation in patients without intervention to the aortic root.

ABSTRACT

Background and Objectives: We aimed to assess the effect of AST/ALT ratio on echocardiographic and cardiac magnetic resonance imaging (CMRI) parameters after COVID-19 patients recover. Materials and Methods: 87 patients with COVID-19 were included in the study. The patients were hospitalized with COVID-19 pneumonia, but the patients did not need intensive care unit follow-up or non-invasive mechanical ventilation support. After a discharge and two weeks following the positive swab test result, patients were considered eligible if they had any symptoms. Transthoracic echocardiography (TTE) was performed within 24 h prior to CMRI. The median value of AST/ALT ratio was found, and the study population was divided into two subgroups based on the median AST/ALT ratio value. The clinical features, blood test, TTE and CMRI results were compared between subgroups. Results: C-reactive protein, D-dimer and fibrinogen were found to be significantly higher in patients with high AST/ALT ratio. LVEF, TAPSE, S', and FAC were significantly lower in patients with high AST/ALT ratio. LV-GLS were significantly lower in patients with high AST/ALT ratio. In CMRI, native T1 mapping signal, native T2 mapping signal and extracellular volume raised significantly in patients with high AST/ALT ratio. Right ventricle stroke volume and right ventricle ejection fraction were significantly lower in patients with high AST/ALT ratio, but right ventricle end systolic volume was significantly higher in patients with high AST/ALT ratio. Conclusion: High AST/ALT ratio is related to impaired right ventricular function parameters with CMRI and echocardiography after recovery from acute COVID-19. Assessment of AST/ALT ratio at hospital admission may be used to assess the risk of cardiac involvement in COVID-19 disease, and these patients may require closer follow-up during and after the course of COVID-19.

ABSTRACT

The coronavirus disease of 2019 (COVID-19)-related myocardial injury is an increasingly recognized complication and cardiac magnetic resonance imaging (MRI) has become the most commonly used non-invasive imaging technique for myocardial involvement. This study aims to assess myocardial structure by T2*-mapping which is a non-invasive gold-standard imaging tool for the assessment of cardiac iron deposition in patients with COVID-19 pneumonia without significant cardiac symptoms. Twenty-five patients with COVID-19 pneumonia and 20 healthy subjects were prospectively enrolled.Cardiac volume and function parameters, myocardial native-T1, and T2*-mapping were measured. The association of serum ferritin level and myocardial mapping was analyzed. There was no difference in terms of cardiac volume and function parameters. The T2*-mapping values were lower in patients with COVID-19 compared to controls (35.37 [IQR 31.67-41.20] ms vs. 43.98 [IQR 41.97-46.88] ms; p < 0.0001), while no significant difference was found in terms of native-T1 mapping value(p = 0.701). There was a positive correlation with T2*mapping and native-T1 mapping values (r = 0.522, p = 0.007) and negative correlation with serum ferritin values (r = - 0.653, p = 0.000), while no correlation between cardiac native-T1 mapping and serum ferritin level. Negative correlation between serum ferritin level and T2*-mapping values in COVID-19 patients may provide a non-contrast-enhanced alternative to assess tissue structural changes in patients with COVID-19. T2*-mapping may provide a non-contrast-enhanced alternative to assess tissue alterations in patients with COVID-19. Adding T2*-mapping cardiac MRI in patients with myocardial pathologies would improve the revealing of underlying mechanisms. Further in vivo and ex vivo animal or human studies designed with larger patient cohorts should be planned.

ABSTRACT

OBJECTIVE: This study aimed to investigate the QT, QTc, and QTc dispersion changes that may occur with the use of hydroxychloroquine (HCQ), favipiravir, and moxifloxacin in combination or alone in COVID 19 patients. METHODS: This study was retrospectively conducted on 193 inpatients diagnosed with COVID-19. We divided the patients into four separate groups due to their medications as, group-1: favipiravir, group-2: favipiravir + HCQ, group-3: favipiravir + moxifloxacin, and group-4: favipiravir + moxifloxacin + HCQ. We recorded their pre and post-treatment QT parameters of each group and evaluated the changes of these parameters with the SPSS statistical program. RESULTS: The mean age of the patients was 63.1±17.7. In group 1 and 2, although there were slight changes in QT parameters, these results were not statistically significant. In group 3, significant increases in QT and QTc dispersion occurred (p=0.005 and p=0.018). In the 4th group where the triple therapy was applied, there was a significant increase only in the QTc values (p=0.027). When we compared the changes of QT parameters for each group, a significant difference was found in ΔQTc dispersion, and post hoc analysis showed that it was due to changes in the third group (p=0.047). CONCLUSION: We thought that, if there is a COVID-19 infection with an additional bacterial infection, and if there is a need of using moxifloxacin alone or together with HCQ, additional risk factors that may cause QT interval prolongation should be reviewed and ECG monitoring of the patients should be performed during the treatment period.

ABSTRACT

BACKGROUND: Prosthetic valve thrombosis (PVT) is one of the life-threatening complications of prosthetic heart valve replacement. Due to the lack of randomized controlled trials, the optimal treatment of PVT remains controversial between thrombolytic therapy (TT) and surgery. OBJECTIVES: This study aimed to prospectively evaluate the outcomes of TT and surgery as the first-line treatment strategy in patients with obstructive PVT. METHODS: A total of 158 obstructive PVT patients (women: 103 [65.2%]; median age 49 years [IQR: 39-60 years]) were enrolled in this multicenter observational prospective study. TT was performed using slow (6 hours) and/or ultraslow (25 hours) infusion of low-dose tissue plasminogen activator (t-PA) (25 mg) mostly in repeated sessions. The primary endpoint of the study was 3-month mortality following TT or surgery. RESULTS: The initial management strategy was TT in 83 (52.5%) patients and surgery in 75 (47.5%) cases. The success rate of TT was 90.4% with a median t-PA dose of 59 mg (IQR: 37.5-100 mg). The incidences of outcomes in surgery and TT groups were as follows: minor complications (29 [38.7%] and 7 [8.4%], respectively), major complications (31 [41.3%] and 5 [6%], respectively), and the 3-month mortality rate (14 [18.7%] and 2 [2.4%], respectively). CONCLUSIONS: Low-dose and slow/ultraslow infusion of t-PA were associated with low complications and mortality and high success rates and should be considered as a viable treatment in patients with obstructive PVT.

ABSTRACT

OBJECTIVES: No studies have been specifically conducted on asthma patients undergoing cardiac surgery for assessing mortality and morbidity. Distinct effects of cardiac surgery lead to negative effects on respiratory functions, putting patients with existing lung diseases under an increased risk. We aimed to investigate whether asthma patients are under higher risk for mortality and possible complications after coronary artery bypass graft (CABG) surgery than patients without asthma. MATERIALS AND METHODS: The study included patients who underwent elective CABG surgery at our hospital between November 2014 and November 2015. Patients with a history of asthma were verified with physical examination and spirometric measurements by a single. The asthma group was compared with the controls in terms of mortality and morbidities. RESULTS: Asthma patients were extubated later than control patients (p=0.028); however, prolonged intubation (longer than 24 h) frequency was not different (p>0.05). Asthma patients required longer stay in the intensive care unit (ICU) (p=0.003) than controls. The incidence of perioperative asthma exacerbations was significantly lower in patients in whom asthma was previously well-controlled. The incidence of postoperative sibilant rhonchi was lower in patients in whom asthma was under control than in those in whom asthma was partially controlled (p=0.020). CONCLUSION: Asthma is associated with longer ICU stay and asthma-related pulmonary complications after CABG surgery. Preoperative evaluation of asthma patients scheduled for CABG surgery requires consideration of the control status of asthma. Studies with more controls are needed to provide further evidence on the topic.

ABSTRACT

INTRODUCTION:: Elevated hemoglobin A1c levels in patients with diabetes mellitus have been known as a risk factor for acute kidney injury after coronary artery bypass grafting. However, the relationship between hemoglobin A1c levels in non-diabetics and acute kidney injury is under debate. We aimed to investigate the association of preoperative hemoglobin A1c levels with acute kidney injury in non-diabetic patients undergoing isolated coronary artery bypass grafting. METHODS:: 202 non-diabetic patients with normal renal function (serum creatinine <1.4 mg/dl) who underwent isolated coronary bypass were analyzed. Hemoglobin A1c level was measured at the baseline examination. Patients were separated into two groups according to preoperative Hemoglobin A1c level. Group 1 consisted of patients with preoperative HbA1c levels of < 5.6% and Group 2 consisted of patients with preoperative HbA1c levels of ≥ 5.6%. Acute kidney injury diagnosis was made by comparing baseline and postoperative serum creatinine to determine the presence of predefined significant change based on the Kidney Disease Improving Global Outcomes (KDIGO) definition. RESULTS:: Acute kidney injury occurred in 19 (10.5%) patients after surgery. The incidence of acute kidney injury was 3.6% in Group 1 and 16.7% in Group 2. Elevated baseline hemoglobin A1c level was found to be associated with acute kidney injury (P=0.0001). None of the patients became hemodialysis dependent. The cut off value for acute kidney injury in our group of patients was 5.75%. CONCLUSION:: Our findings suggest that, in non-diabetics, elevated preoperative hemoglobin A1c level may be associated with acute kidney injury in patients undergoing coronary artery bypass grafting. Prospective randomized studies in larger groups are needed to confirm these results.

ABSTRACT

OBJECTIVE: Recent studies have demonstrated that preoperative statin therapy reduces the incidence of postoperative atrial fibrillation (AF). The objective of this study was to assess the efficacy of statin therapy started in the early postoperative period for the prevention from new-onset AF after isolated coronary artery bypass grafting (CABG). METHODS: This prospective and randomized study consisted of 60 consecutive patients who underwent elective isolated CABG. Patients were divided into two groups to examine the influence of statins: those with postoperative statin therapy (statin group, n=30) and those without it (non-statin group, n=30). Patient data were collected and analyzed prospectively. In the statin group, each extubated patient was given 40 mg of atorvastatin per day, starting from an average of 6 hours after the operation. RESULTS: The overall incidence of postoperative AF was 30%. Postoperative AF occurred in 5 patients (16.7%) in the statin group. This was significantly lower compared with 13 patients (43.3%) in the non-statin group (p=0.049). According to the multivariate analysis, postoperative atorvastatin reduced the risk of postoperative AF by 49% [odds ratio (OR) 0.512, 95% confidence interval (CI) 0.005 to 0.517, p=0.012]. Also, age was an independent predictor of postoperative AF (OR 1.299, 95% CI 1.115 to 1.514, p=0.001). CONCLUSION: Postoperative statin therapy seems to reduce new-onset AF after isolated CABG in our study.

ABSTRACT

OBJECTIVE: The aim of this study is to investigate the putative neuroprotective effect of alpha-lipoic acid (LA) on spinal ischemia/reperfusion (I/R) injury in rabbits. METHODS: Thirty-five adult female New Zeland rabbits, weighing 2,000-3,500 g (mean: 2,800), were divided randomly into five groups of seven rabbits each (n: 7) as Group 1: sham, only laparotomy; Group 2 (I/R): I/R; Group 3 (LA): I/R and 100 mg/kg of LA; Group 4 (MP): I/R and 30 mg/kg of methylprednisolone (MP); and Group 5 (LA + MP): I/R and 100 mg/kg of LA plus 30 mg/kg of MP. RESULTS: A statically significant effect of LA, MP, and LA plus MP on lowering malondialdehyde levels both in the blood and in the cerebrospinal fluid (CSF) has been observed. Nitric oxide is significantly decreased in the blood and spinal cord tissues, and also in the CSF but it is not significant. Superoxide dismutase, catalase, and glutathione levels were increased by LA administration. CONCLUSION: LA exhibits antioxidant efficacy in spinal cord I/R injury, but it cannot decrease the oxidative stress. The histopathological result of the present study also demonstrated that LA has neuroprotective effect in spinal cord injury.

ABSTRACT

OBJECTIVES: Lymphatic complications, lymphocele and lymphorrhea being the leading, are generally encountered after vascular interventions and surgeries. The present study aimed to evaluate the outcomes of vacuum-assisted-closure (VAC) therapy, which we frequently prefer as the first-choice treatment for such complications. MATERIALS AND METHODS: Among patients undergoing peripheral vascular intervention or surgery between January 2008 and February 2012, the medical files of 21 patients who received VAC therapy or other treatment due to symptomatic lymphatic complications were retrospectively analyzed and the results were discussed. RESULTS: Group I consisted of 10 patients (three with lymphocele and seven with lymphorrhea) who underwent VAC therapy as the first-choice treatment, Group II consisted of 11 patients of which 7 patients received various therapies before VAC therapy and 4 patients received other treatments alone. The patients who received VAC therapy as the primary therapy demonstrated more rapid wound healing, early drainage control, and shorter hospital stay. The mean hospital medical cost was €1038 (range, €739-1826) for the patients who primarily underwent VAC therapy; it was calculated to be €2137 (range, €1610-3130) for the other patients (p=0.001). CONCLUSION: In addition to its safety and good clinical outcomes, VAC therapy also has economic advantages and should be the primary method for the treatment of lymphatic complications.

ABSTRACT

OBJECTIVE: Ventricular fibrillation is common after aortic declamping in patients undergoing open heart surgery. This situation has a negative impact on morbidity and mortality. The aim of this prospective study was to compare the effect of administering lidocaine versus amiodarone before aortic declamping during elective coronary bypass grafting, paying close attention to when the initial effect of amiodarone sets in. METHODS: In this double blind, prospective, randomized, controlled study, 86 patients who were candidates for elective coronary artery bypass grafting were recruited into three groups: group lidocaine (group L, n=29); group amiodarone (group A, n=27); and group placebo (group P, n=30). Group L patients received 1.5 mg/kg of lidocaine 2 minutes before aortic declamping and group A patients received 300 mg of amiodarone intravenously 15 minutes before release of the aortic cross clamp. The primary endpoints were the incidence of ventricular fibrillation and the number of shocks required to terminate ventricular fibrillation. RESULTS: The frequency of ventricular fibrillation occurrence was significantly higher in group P (70%) when compared with group A (37%) and group L (38%) (P=.017). There was no statistically significant difference between the amiodarone and the lidocaine groups regarding ventricular fibrillation. However, when ventricular fibrillation occurred, the percentage of patients requiring electrical defibrillation was significantly higher in both group L and group P when compared with group A (P=.023). CONCLUSION: We suggest that during coronary arterial bypass surgery, administration of an amiodarone regime before release of the aortic cross clamp, paying particular attention to the start of the initial effect of amiodarone, is no more effective than lidocaine for prevention from arrhythmia; however, amiodarone reduces the need for electrical defibrillation.

ABSTRACT

BACKGROUND AND OBJECTIVE: Evaluation of graft patency is an important component of coronary bypass surgery. In the present study, intraoperative cineangiography was performed in a cardiovascular hybrid operating room to evaluate anastomosis quality and patency of coronary venous grafts. METHOD: This prospective study evaluated coronary bypass grafts in 34 patients between January 2012 and June 2012. Radiopaque material was administered into the grafts through a vessel cannula before the proximal anastomosis. Then, cineangiographic images were obtained using a mobile C-arm cineangiography system. The myocardial perfusion scintigraphy (MPS) of the patients was compared between preoperative and first month postoperative periods to assess graft function. RESULTS: The localization of the grafts in the target vessel, structural status of the grafts, anastomosis line, and availability of the target vessel were easily evaluated. Angiographic defects were detected in two grafts (3%, n = 60) in two patients (6%, n = 34). Staining was observed in the distal myocardial segments of the saphenous vein grafts following the administration of radiopaque material. The procedure took eight minutes, on average (range, 5-14 minutes), and a mean of 15 mL (range, 10-35 mL) of opaque material was used. None of the patients developed intraoperative myocardial infarction, postoperative complications, or contrast material-induced renal failure. No mortality was observed. The distal myocardial segments of saphenous vein grafts were detected to be perfused 92% normally, 5% reversibly defective, and 3% irreversibly defective with postoperative MPS controls. CONCLUSION: Cineangiographic graft evaluation in a hybrid operating room is a practical, safe, noninvasive, easily available, and easily applicable method.

ABSTRACT

Intraoperative detection of deeply embedded coronary arteries is difficult. This study describes an effective method to identify embedded coronary arteries by intraoperative cine angiography. Two embedded left anterior descending coronary arteries were successfully identified by intraoperative cine angiography. We believe that the intraoperative cineangiography is helpful for surgeons in this difficult situation.

ABSTRACT

Pseudoaneurysm and aorto-cutaneous fistula following surgical procedures of the aorta are rare complications with potentially catastrophic results that require rapid diagnosis and urgent surgical treatment. We performed a successful life-saving operation using hypothermic circulatory arrest with femoral artery and vein cannulation. The patient had undergone open heart surgery in our clinic twice, and there was active and abundant bleeding from aorta-cutaneous fistula that occured 5 years after the last surgery.

ABSTRACT

We report a patient and his family, who have branchio-oto-renal (BOR) syndrome and coexisting mitral valve prolapse. A literature review of BOR syndrome failed to identify any similar families and we report this as a new observation. During the preoperative assessment of a patient with BOR syndrome, tachycardia was noted and a cardiologic examination including echocardiography revealed mitral valve prolapse. Members of his extended family were investigated, including carrying out cardiology and otolaryngology examinations to determine whether they had signs of either BOR syndrome or cardiac problems. Mitral valve prolapse was identified in five (71.4%) of the seven BOR syndrome patients in the family. Deafness was present in all patients. Distribution of the other clinical findings of the BOR syndrome patients were as follows: branchial fistula in five (71.4%), preauricular pits in four (57.1%), ear deformity in two (28.5%), renal anomalies in three (42.8%), lacrimal duct anomaly in two (28.5%) and orbital anterior compartment anomaly in one (14.2%). We conclude that mitral valve prolapse can be associated with BOR syndrome. Further large studies are needed to clarify this association.
