Effect of low-dose methyl prednisolone on serum cytokine levels following extracorporeal circulation:

The systemic inflammatory response to cardiopulmonary bypass (CPB) is associated with increased production of cytokines. This systemic inflammatory response characterized by the activation of interleukin-6 (IL-6) and interleukin-8 (IL-8) during and after CPB is well documented. A prospective, randomized, double-blind study was performed so as to understand the effects of low-dose methyl prednisolone sodium succinate (MPSS) on the circulating levels of serum cytokines and clinical outcome. Twenty patients were randomly divided into two groups on the basis of the administration of low-dose (1 mg/kg) MPSS (n = 10) and placebo (n = 10) into the pump prime solution. All patients were scheduled to undergo a primary elective coronary artery bypass grafting operation. Patients receiving concurrent corticosteroids, salicylates, dipyridamol or anticoagulants were excluded from the study. Other exclusion criteria were concurrent chronic obstructive pulmonary disease, chronic renal failure, insulin-dependent diabetes, congestive cardiac failure, peptic ulcer history, prior cardiac operations, recent (in a one-month period) myocardial infarction and steroid dependency. Mild systemic hypothermia (30-32°C, rectal) was assured during the CPB. Four blood samples were drawn from the radial artery catheter immediately before starting CPB (T1), following protamine administration (T2) and at 24 (T3) and 48 h (T4) after completion of CPB. In each sample, creatine kinase-myocardial band (CK-MB), white blood cell (WBC), IL-6 and IL-8 levels were measured. IL-6 and IL-8 concentrations were measured by enzyme immunoassay and enzyme-linked immunoabsorbant assay methods. Serum IL-6 T2 and serum IL-6 T3 levels were significantly higher than IL-6 T1 levels in both groups (p < 0.001) and (p < 0.01), and there was no significant elevation in serum IL-8 levels in either group. Serum IL-6 levels were significantly higher in the placebo group than in the MPSS group at T3 (p < 0.009). There was no significant difference in CK-MB T1 levels between the groups. Although there was no significant difference between CK-MB T1 and T2 levels in the MPSS group, the CK-MB T2 and CK-MB T3 levels were significantly higher than T1 levels in the placebo group (p < 0.001) and (p < 0.05). There was significant elevation of WBC levels at T2 and T3 in both groups without notable difference between the groups (p < 0.05). This study has shown that low-dose MPSS suppresses CPB-induced inflammatory response. Further clinical studies (on larger and higher risk groups) may reveal more information on relations between morbidity and cytokine levels which may have some predictive value on clinical outcome following CPB.

Asymptomatic Balanced-Type Double Aortic Arch in an Elderly Patient: A Case Report

Double aortic arch is a congenital abnormality and sporadic cases have been reported in adult patients, who are usually diagnosed after complaining of asthma-like symptoms or swallowing difficulties because of the compression of the trachea or esophagus by the abnormal aortic arches. We present the case of a 67-year-old male patient with double aortic arch, found coincidentally during coronary angiographic examination.

Direct reimplantation technique via a right minithoracotomy for scimitar syndrome: a case report.

Scimitar syndrome (SS) is a rare congenital cardiac anomaly defined by an anomalous right pulmonary vein draining of the right lung into the inferior vena cava. We describe a direct reimplantation technique and atrial septal defect closure using cardiopulmonary bypass via a right minithoracotomy on a 24 year-old female SS patient who had an accompanying sinus venous atrial septal defect.

Cardiac and caval invasion of left adrenocortical carcinoma.

Adrenocortical carcinoma (ACC) is a rare and highly malignant neoplasm. We present the case of a 51-year-old male patient with a left-sided ACC admitted to hospital with ipsilateral flank pain, weight loss, difficulty in breathing, abdominal discomfort and swelling and bilateral leg edema. Thoracoabdominal computed tomography revealed a huge adrenal mass with obvious tumor thrombus involvement of the inferior vena cava and right atrium. This is the first report describing caval and opposite side renal vein invasion of a left-sided ACC treated with grafting of the vessels. Histopathological examination of the tumors confirmed the diagnosis of ACC. Postoperative recovery was uneventful. The patient received an adrenolytic agent, mitotane, postoperatively and is alive with no evidence of recurrence after 2 years of follow-up.

Complete Atrioventricular Block due to a Hydatid Cyst Located in the Interventricular Septum: A Case Report

We report a case of complete atrioventricular block and tricuspid valve insufficiency due to a cardiac hydatid cyst located in the interventricular septum that occurred in a 19-year-old male patient. Surgery was carried out with the help of cardiopulmonary bypass. The cyst was excised, and the interventricular septum was closed with an autologous pericardial patch treated with glutaraldehyde. The tricuspid valve insufficiency was repaired with annuloplasty. A dual-chamber epicardial pacemaker was implanted. The postoperative course was uneventful, and the patient was doing well 6 months after discharge. This is the first report of a cardiac hydatidosis case for which the repair of the interventicular septum, tricuspid annulopasty, and permanent pacemaker implantation were performed during the same operation.

Single-stage repair of adult aortic coarctation and concomitant cardiovascular pathologies: a new alternative surgical approach

BackgroundCoarctation of the aorta in the adulthood is sometimes associated with additional cardiovascular pathologies that require intervention. Ideal approach in such patients is uncertain. Anatomic left-sided short aortic bypass from the arcus aorta to descending aorta via median sternotomy allows simultaneuos repair of both complex aortic coarctation and concomitant cardiac operation.MaterialsFour adult patients were underwent Anatomic left-sided short aortic bypass operation for complex aortic coarctation through median sternotomy using deep hypothermic circulatory arrest. Concomitant cardiac operations were Bentall procedure for annuloaortic ectasia in one patient, coronary artery bypass grafting for three vessel disease in two patient, and patch closure of ventricular septal defect in one patient.ResultsAll patients survived the operation and were alive with patent bypass at a mean follow-up of 36 months. No graft-related complications occurred, and there were no instances of stroke or paraplegia.ConclusionWe conclude that single-stage repair of adult aortic coarctation with concomitant cardiovascular lesions can be performed safely using this newest technique.

Postoperative outcomes after off-pump coronary artery bypass grafting in EuroSCORE low- and high-risk women.

BACKGROUND Many previous studies have reported that women who undergo coronary artery bypass grafting have higher perioperative morbidity and mortality rates than men. The use of off-pump coronary artery bypass grafting (OPCAB) has been suggested to decrease morbidity and mortality because the deleterious effects of cardiopulmonary bypass, particularly in high-risk patients, are avoided. The reduction in unwanted postoperative complications in women undergoing OPCAB surgery has not been extensively investigated. The aim of this retrospective study was to compare perioperative rates of morbidity and mortality and follow-up events after OPCAB in female patients assessed as high- or low-risk according to the European System for Cardiac Operative Risk Evaluation (EuroSCORE). METHODS The study included 377 adult female patients who underwent elective primary isolated OPCAB. The study patients were divided into 2 groups based on the Additive EuroSCORE: low-risk patients (group I, n = 301, EuroSCORE < 6) and high-risk patients (group II, n = 76, EuroSCORE > or = 6). RESULTS Patient ages were 60.1 +/- 7.77 years in group I and 69.3 +/- 5.51 years in group II (P <.001). Compared to group I patients, group II patients had significantly higher Additive EuroSCORE (P <.001), predicted mortality rate (Logistic EuroSCORE) (P <.001), and Canada angina classification (P <.001) and higher rates of preoperative myocardial infarction (P <.001), peripheral vascular disease (P <.001), carotid artery disease (P <.005), and hypertension (P <.05). Occurrence of postoperative arrhythmia and mortality were significantly higher (P <.05) in group II. The observed mortality rate in group I was 1%, which was 41% of the predicted mortality rate (Logistic EuroSCORE) of 2.42 +/- 0.76. The observed mortality rate in group II was 5.3%, which was 79% of the predicted rate (6.74 +/- 2.89), but the difference was not significant (P = .2). Intensive care unit length of stay (P <.01) and ventilation times (P <.05) were longer for group II than group I, and the incidence of conversion to cardiopulmonary bypass was 1.6% versus 5.3%, respectively, in groups I and II (P = .08). CONCLUSION These results indicate that OPCAB surgery is safe and seems to be an effective surgical technique for lowering rates of morbidity and mortality in high- and low-risk female patients.

Multicentric Cardiac Myxoma Treated with Extended Surgery

We present the case of a 37-year-old male patient with a multicentric myxoma admitted to hospital with dyspnoea, syncope and chest pain. Physical examination revealed a grade 3/6 systolic murmur at the left lower sternal border and diffuse bilateral lung rales. Transthoracic echocardiography and thoraco-abdominal computed tomography revealed a right atrial mass and a right ventricular mass obstructing the outflow tract. The patient underwent urgent surgical treatment. At operation, a solitary right atrial myxoma and a right ventricular myxoma originating from the tricuspid valve and attached to the free wall of the right ventricle were seen. The tumours were successfully excised and the tricuspid valve was replaced with a No. 33 Omnicarbon® metallic valve. The right ventricular free wall was repaired with a glutaraldehyde-treated pericardial patch. Histopathological examination of the tumours confirmed the diagnosis of myxoma. Post-operative recovery was uneventful and there was no recurrence after 1 years follow-up.
