[Appropriateness of the request for preoperative cardiological evaluation in non-cardiac surgery: 8-year experience in a high-volume cardiological center].

Background: In the last decades the population undergoing non-cardiac surgery has become more numerous and complex. Cardiovascular perioperative complications represent at least one third of the perioperative deaths. Despite the pivotal role of the cardiologist in the perioperative management, current guidelines are often hardly useful in different settings of clinical practice.

Preoperative assessment of cardiovascular risk in patients undergoing noncardiac surgery: the Orion study.

In patients undergoing noncardiac surgery risk indices can estimate patients' perioperative risk of major cardiovascular complications. The indexes currently in use were derived from observational studies that are now outdated with respect to the current clinical context. We undertook a prospective, observational, cohort study to derive, validate, and compare a new risk index with established risk indices.

[Sudden death from lipomatous hamartoma of the heart].

The authors report a case of a patient arrived at their observation in cardiogenic shock. The ECG showed extreme bradycardia refractory to resuscitation manoeuvres. The autopsy showed a lipomatous hamartoma in the interatrial septum.
