Does Aspartate Aminotransferase to Alanine Aminotransferase Ratio Predict Acute Kidney Injury After Cardiac Surgery?

Background: Aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio (AST/ALT) frequently is used in the diagnosis and prognosis of liver diseases, however it is also used in the diagnosis and prognosis of many other diseases, such as myocardial infarction, acute ischemic stroke, and peripheral artery disease. Acute kidney injury (AKI) is one of the most important complications after cardiac surgery and is one of the main causes of morbidity and mortality. The purpose of the study was to analyze the relationship between AST to ALT and AKI after isolated coronary artery bypass graft surgery (CABG).

Transient Diabetes Insipidus Following Cardiopulmonary Bypass.

Diabetes insipidus (DI) results from inadequate output of Antidiuretic Hormone (ADH) from the pituitary gland (central DI) or the inability of the kidney tubules to respond to ADH (nephrogenic DI). ADH is an octapeptide produced in the supraoptic and paraventricular nuclei of the hypothalamus and stored in the posterior lobe of the pituitary gland. Cardiopulmonary Bypass (CPB) has been shown to cause a six-fold increased circulating ADH levels 12 hours after surgery.

Translocation of anomalous right coronary artery to aortic side of the aortopulmonary window: a different approach for a rare combination.

A case of aortopulmonary window associated with anomalous origin of the right coronary artery from the pulmonary artery in a four-month-old boy is reported in this paper with a different method of repair. In this patient, surgical repair was done by transferring the right coronary artery from the pulmonary artery to the aorta at the aortopulmonary window side. The defect at the pulmonary artery was repaired by a pericardial patch, so no other secondary opening was used for the aorta in order to reimplant the coronary artery.
