Cardiac hydatid cyst is a rare condition, and the location of a hydatid cyst in the interventricular septum is exceptional. A 54-year-old female was admitted to our hospital with complaints of chest pain, shortness of breath and malaise. Transthoracic echocardiography defined a cystic mass lesion of 50 × 59 mm originating from apex of the heart protruding into and compressing the interventricular septum. The cyst was excised surgically and the patient was discharged on the 8th postoperative day without symptoms. In our case, localization of the cystic mass was within interventricular septum which is an uncommon site. It limited both ventricular volumes significantly. In addition, this cyst was extensively protruding to the right ventricular epicardium.
BACKGROUND: Penetrating cardiac injuries are high-risk, high-mortality injuries considering the outcomes. Therefore, it is important to choose the appropriate incision. In general clinical settings, thoracotomy and median sternotomy are choices of incisions to explore the injury. In this study, the results of median sternotomy and thoracotomy in penetrating cardiac injuries were compared.
Background Coronavirus disease 2019 (COVID-19) causes thromboembolic complications during or post-infection period despite a lack of conventional risk factors. The study aims to learn fundamental changes in COVID-19 patients who underwent embolectomy in terms of clinical characteristics and clot composition. Methods In a retrospective cohort study design, we evaluated 21 patients who underwent embolectomy in our clinic between March 12, 2020, and December 31, 2020. Demographics, characteristics, and laboratory values were abstracted and analyzed. Histopathological assessment was held in the pathology department. Results Of these 21 patients, 11 (52.3%) were SARS-CoV-2 positive and 10 (47.6%) were SARS-CoV-2 negative. There is no statistical difference in terms of anatomic distribution, diagnostic method, length of hospital stay, amputation or mortality levels. Thromboembolic material of COVID-19 patients include significantly less red blood cell (RBC) (21.2–32.6%; P = 0.01), more lymphocyte (14.1–2.6%; P < 0.001), and more leukocyte (27.1–22.1%; P = 0.05). There was no statistical difference between the fibrin ratio. Conclusions Inflammatory cells are prominent in arterial thromboembolic material of COVID-19 patients. A combination of hyperinflammation and prothrombotic status may be responsible for this phenomenon.
ObjectiveTreatment of acute diseases of the aorta is still associated with high mortality and morbidity. It is believed that interventions for these diseases on overtime hours (night shifts or weekend shifts) may increase mortality. In this study, we investigated the effect of performing acute type A aortic dissection surgery on overtime hours in terms of postoperative outcomes.Methods206 patients who underwent emergency surgery for acute type A aortic dissection were retrospectively evaluated. Two groups were constituted: patients operated on daytime working hours (n=61), and patients operated on overtime hours (n=145), respectively.ResultsChronic obstructive pulmonary disease and repeat surgery were higher in group 1. There was no statistically significant difference between the two groups in terms of operative and postoperative results. Mortality rates and postoperative neurological complications in group 1 were 9.8% and 13.1%, respectively. In group 2, these rates were 13.8% and 12.4%, respectively (P=0.485 - P=0.890). Multivariate analysis identified that cross-clamp time, amount of postoperative drainage, preoperative loss of consciousness and postoperative neurological complications are the independent predictors of mortality.ConclusionsAs the surgical experience of the clinics improves, treatment of acute type A aortic dissections can be successfully performed both overtime and daytime working hours.
Atrial fibrillation (AF) is a cardiac dysrhythmia commonly seen in clinical practice especially after cardiac surgery. It is associated with increased morbidity and mortality for the patients. The pathogenesis of AF is not exactly understood yet, but there is growing data about the relationship between AF and inflammation. Cardiac surgery itself is a big source for inflammation. It causes major surgical trauma, ischemia/reperfusion injury, hypothermia, low arterial pressure, and the equipment of cardiopulmonary bypass makes a large foreign surface thus it activates inflammatory response. There is a large number of data about the treatment options of AF and there are also strategies, which are related to reduction of inflammatory activation during cardiopulmonary bypass. In order to review the relationship between cardiac surgery, inflammation, AF and treatment strategies in patients with AF, we conducted a search through Pubmed for articles in English using the keywords: "atrial fibrillation, cardiac surgery, inflammation, medical therapy, surgical therapy, ablation therapy" from January 2012 to present. We also searched separately for each alternative treatment modality on Pubmed. To identify further articles, we also looked into related citations in review articles and commentaries. We searched thoroughly the guidelines published by the European Society of Cardiology (2016), and the American Heart Association/ American College of Cardiology/ Heart Rhythm Surgery (2014). Many studies concluded that inflammation contributes in the occurrence of AF. Inflammatory markers, such as CRP, interleukins and complements have high sensitivity and specificity for prediction of AF whether the patient having cardiac surgery or not. Betablockers, diltiazem and amiodarone are the most commonly used drugs for rate control in AF following surgery. Although there are some new therapeutic approaches to reduce postoperative inflammatory activation, such as the use of vitamins, fatty acids, statins, or technical improvements to cardiopulmonary bypass unit like miniaturized bypass circuits, heparin coating of the circuits, leukocyte filters, or various surgical approaches like off-pump coronary bypass surgery, we still need more effective strategies to reduce both postoperative inflammation and postoperative AF risk after cardiac surgery. Today we use more advanced invasive and surgical treatment strategies for AF although we need far more advanced technics to reduce perioperative inflammatory activation, which actually causes AF.
SummaryBackgroundCoronary artery bypass (CAB) surgery triggerssystemic inflammatory response syndrome (SIRS) via severalmechanisms. Moreover, age is directly correlated with SIRS.We evaluated the effect of age on SIRS and postoperativeoutcome after CAB surgery.MethodsWe retrospectively reviewed the records of 229 patients who had undergone CAB surgery. The patients were divided into three groups according to age: group 1, < 40 years (n = 61); group 2, 40–75 years (n = 83); and group 3, > 75 years old (n = 85). Pre- and peri-operative data were assessed in all patients. SIRS was diagnosed according to the criteria established by Boehme.ResultsThe average pre-operative EuroSCORE value in group 3 was higher than in the other groups and body surface areas were significantly lower in group 3 than in the other groups (p < 0.05). The postoperative SIRS rates were 68.9% in group 1, 84.3% in group 2 and 91.8% in group 3 (group 1 vs group 3; p < 0.05). Mortality rates were not significantly different between the groups (p > 0.05). The predictive factors for SIRS were age, EuroSCORE rate, on-pump CAB surgery and intra-aortic balloon pump use.ConclusionAge was an important risk factor for SIRS during the postoperative period after CAB.
Objective Since the systemic drugs have been used to reduce the hyperplasic response in the tunica intima, the periadventitial local drug applications to the vascular wall have gained more popularity. In this study, we investigated the effect of bovine serum albumin-glutaraldehyde and polyethylene glycol polymer on neointimal hyperplasia in rabbit carotid artery anastomosis to explore the effects of these two different agents. Methods 21 New Zealand male rabbits were randomly divided into three groups. The carotid artery transection and anastomosis was performed onthe control group. The bovine serum albumin-glutaraldehyde and the polyethylene glycol polymer were applied locally on the other two groups seperatley after transection and anastomosis of the carotid arteries. At the end of 28-day follow-up, the histological and the immunohistochemical results related to neointimal hyperplasia were compared. Results The glue residues were detected in the BSA-glutaraldehyde group, but in the PEG polymer group there was no glue residue. The intima thickness and the intima/media thickness ratio in the control group was significantly higher (p<0.05) than the other groups. These values did not differ significantly between the BSA-glutaraldehyde group and the PEG polymer group (p>0.05). The lumen diameter and the area in the control group were significantly higher (p < 0.05) than the BSA-glutaraldehyde group. These values between the control group and the PEG polymer group did not differ significantly (p>0.05). aSMA-positive staining score in the Control group was found to be significantly lower (p < 0.05) than the BSA-glutaraldehyde and PEG polymer group and the VEGF-positive staining score in the control group was found to be significantly higher (p < 0.05) than the BSA-glutaraldehyde and the PEG polymer group. Conclusions Although the both agents have positive results on neointimal hyperplasia, it would be favorable to use polyethylene glycol polymer, since it does not seem to affect the lumen area and the lumen diameter of the vessel.
