Assessment of Diastolic Function in High Risk Patients Undergoing Major Vascular Surgery

Heart Failure Clinical Trial

Official title: Assessment of Left Ventricle Diastolic Function in High Risk Patients Undergoing Major Vascular Surgery as an Early Indicator of Cardiac Failure. Observational Study

Status Completed

Clinical Trial Summary

Patients scheduled for Thoracic Endovascular Aortic Repair (TEVAR) surgery will have transthoracic echocardiography evaluation of left ventricle diastolic function during the perioperative period.

Clinical Trial Description

Patients undergoing TEVAR surgery are a high risk group of developing perioperative cardiovascular complications.

Left ventricle diastolic dysfunction is common in this group of patients because of the prevalence of risk factors: > 60 years old, hypertension, smoking history and diabetes.

Because of many predisposing factors that occur during the surgery: stress respond, fluid shifts, anaesthesia and mechanical ventilation. Deterioration of the diastolic function is likely to occur in perioperative period

In this study, the investigators will evaluate change in left ventricle diastolic function as a marker for early detection of a myocardial failure in patients scheduled for an elective TEVAR surgery. The examination will be performed preoperatively, shortly after the surgery and 24 hours after the surgery.

Aim: The aim of the study is to evaluate the diastolic function of left ventricle in perioperative period after high risk surgery. This may provide a valuable information in preoperative risk stratification and postoperative therapy guidance. ;
