Junctional Ectopic Tachycardia After Congenital Heart Surgery: Incidence, Risk Factors, and Outcomes.

Objective: Postoperative junctional ectopic tachycardia (JET) is usually a self-limiting condition; however, when combined with atrioventricular dissociation and postoperative ventricular dysfunction, it may increase morbidity and mortality. This study aimed to determine the overall incidence of JET following congenital heart surgery, to identify patient and procedure-related risk factors, and to evaluate the clinical impact of JET on outcomes.

Methods: The records of 2,814 patients who underwent cardiac surgery over a five-year period were reviewed retrospectively to identify those with JET.

Methods: A retrospective chart review of all extracardiac Fontan patients in a single tertiary care center was undertaken. Patients with a diagnosis of hypoplastic left heart syndrome and those who had undergone a lateral tunnel modification, intra/extracardiac Fontan, Kawashima procedure, or inferior vena cava-to-azygous vein connection were excluded from the analysis.

Randomized comparison between mild and moderate hypothermic cardiopulmonary bypass for neonatal arterial switch operation.

Objectives: To compare neonates receiving arterial switch operation (ASO) either with mild or moderate hypothermic cardiopulmonary bypass.

Methods: Forty neonates undergoing ASO were randomized to receive either mild (Mi > 32 °C, n = 20) or moderate (Mo > 26 °C, n = 20) hypothermic cardiopulmonary bypass (CPB) between April 2007 and June 2010. All patients were diagnosed with simple transposition of the great arteries.

Asymmetric dimethylarginine levels in Buerger's disease.

Background: Endothelial dysfunction may play a major role in both peripheral arterial disease (PAD) and Buerger's disease (BD). Asymmetric dimethylarginine (ADMA) is an endogenous inhibitor of endothelial nitric oxide synthase and increased ADMA levels impair vascular homeostasis. We aimed to determine the plasma levels of ADMA and evaluate the relationship of ADMA levels with smoking and clinical severity of the disease in patients with BD and to compare these results with those of patients with PAD and healthy individuals.

Simultaneous operation in a patient with coronary heart disease, abnormal orifice of coronary arteries, morgagni hernia, atrial septal defect, and pericardial and pleural agenesis.

A 68-year-old male patient with acute coronary syndrome was referred to our center. He also received a diagnosis of diaphragmatic hernia after a clinical examination. The patient underwent a simultaneous aorta coronary bypass operation and repair of the congenital diaphragm hernia.

Tetraplegia after coronary artery bypass surgery in a patient with cervical herniation.

Tetraplegia is a rare complication after coronary artery bypass surgery. The authors present a case of tetraplegia after uncomplicated coronary artery bypass surgery because of cervical disc herniation. No distinct abnormality was found in the preoperative neurologic examination although the postoperative cervical magnetic resonance imaging revealed a huge hernia at C5-C6 level presenting with tetraplegia.

Objective: The aim of this study was to compare the effects of two different cardioplegic solutions on nitric oxide (NO) release from coronary vasculature in patients with type II diabetes mellitus undergoing coronary artery bypass grafting (CABG) surgery.

Methods: Forty patients undergoing elective CABG surgery were randomized to be given crystalloid (Group 1) or blood (Group 2) cardioplegia. Aortic and coronary sinus blood samples were taken at three different time periods and the release of NO from the coronary vasculature was determined by measuring its stable end-products, nitrite and nitrate.

A comparison of the acute hemodynamic effects of inhaled nitroglycerin and iloprost in patients with pulmonary hypertension undergoing mitral valve surgery.

Background: Since the presence of pulmonary hypertension (PHT) affects the prognosis of the patients, it is important to manage and evaluate PHT. The aim of this study was to compare the hemodynamic effects of inhaled nitroglycerin and iloprost during early postoperative period, in patients with PHT undergoing mitral valve replacement surgery.

Materials And Methods: One hundred patients with PHT (mean pulmonary artery pressure (MPAP) >25 mmHg at rest), were randomized to receive either inhalation of nitroglycerin (group I; n=50) or iloprost (group II; n=50) in the postoperative period.

Continuous positive airway pressure does not improve lung function after cardiac surgery.

Purpose: Despite the well-documented impairment of pulmonary function after cardiopulmonary bypass, effective precautions and ideal management strategies for this problem are still under debate. This study aimed to evaluate the effects of continuous positive airway pressure (CPAP) applied during cardiopulmonary bypass on respiratory and hemodynamic variables.

Methods: In this randomized, prospective, controlled trial, 120 male patients, aged 45 to 70 yr undergoing first-time elective bypass surgery, were randomly assigned to receive either 10 cm H2O of CPAP (Group I; n = 60) during cardiopulmonary bypass, or serve as control (Group II; n = 60), where the patient's lungs were vented to atmosphere during the bypass period.

Methods: One hundred and twenty patients were prospectively randomized to be given either insulin (Group 1;n=60), or saline (Group 2;n= 60). Blood samples were taken 15 minutes before the reperfusion and insulin was given (0.

Effect of nitroglycerin inhalation on patients with pulmonary hypertension undergoing mitral valve replacement surgery.

Background: The aim of this study was to investigate the postoperative hemodynamic effects of nitroglycerin inhalation on patients with pulmonary hypertension undergoing mitral valve replacement surgery.

Methods: Twenty patients who underwent mitral valve replacement surgery were included in the study. In the surgical intensive care unit, at T0 (before the inhalation of nitroglycerin), basal systemic and pulmonary hemodynamics were recorded.

Daily comparison of respiratory functions between on-pump and off-pump patients undergoing CABG.

Objective: Widespread application of on-pump revascularization procedures is increasing due to the thought of elimination of untoward effects of cardiopulmonary circuit. Thus, whether off-pump coronary artery surgery eliminates side effects especially related to respiratory functions is still controversial. Although many previous studies have evaluated these respiratory functions, daily comparison of 12 parameters was not included in any of the studies.

Accelerated recovery after cardiac operations.

Background: The accelerated-recovery approach, involving early extubation, early mobility, decreased duration of intensive care unit stay, and decreased duration of hospitalization has recently become a controversial issue in cardiac surgery.

Methods: We investigated timing of extubation, length of intensive care unit stay, and duration of hospitalization in 225 consecutive cardiac surgery patients. Of the 225 patients, 139 were male and 86 were female; average age was 49.
