Use of transthoracic echocardiography to assess left ventricular volume in total hip joint replacement.

This study is looking at whether a type of heart ultrasound called transthoracic echocardiography can be used to measure the amount of blood in the heart's left chamber during hip replacement surgery. This non-invasive test may help doctors better monitor patients during the operation to keep them safe. You may be eligible if: - You are scheduled for a planned (elective) right-sided total hip joint replacement You may NOT be eligible if: - You have a medical reason that prevents you from having spinal anaesthesia - You have poorly controlled heart failure Talk to your doctor about whether this trial might be right for you.
