Intraoperative Takotsubo Syndrome.

Takotsubo cardiomyopathy is a rare condition that presents a diagnostic challenge due to its close resemblance to acute myocardial ischemia and other cardiac disorders. The excessive production of catecholamines triggers abnormal and severe changes in the myocardium, typically resulting in significant dyskinesia of the left ventricle's apex, reduced ejection fraction, hypotension, and pulmonary edema. Recent reports suggest that potential risk factors may include postmenopausal syndrome and intense, unexpected stress, whether related to life events or medical conditions.

Coarctation of Aorta and Post-Stenotic Dissecting Aortic Aneurysm Successfully Treated with Endovascular Stent.

Coarctation associated with a dissected aneurysm is uncommon and has an incidence of less than 1%. There are few reports describing treatment of this condition with stent graft. Challenging as it may be, endovascular treatment of complex cases has become the preferred modality especially when the anatomy is amenable.

From Pre-Existing Renal Failure to Perioperative Renal Protection: The Anesthesiologist's Dilemmas.

Context: Pre-existing renal dysfunction presents specific features that anesthesiologists must deal with. Anesthesia and renal function are connected and can interfere with each other. Induced hypotension anesthesia and the toxic effects of anesthetic drugs can further deteriorate renal function.
