Metrics details. Cardiorenal syndrome CRS is a group of pathophysiological disorders affecting heart and kidneys. We present year-old kidney transplant recipient with acute-on-chronic graft failure in the course of CRS due to acutely decompensated heart failure associated with severe aortic regurgitation successfully treated with aortic valve replacement. Because of graft failure progression and difficult to eradicate infections he was treated with dialysis and radical minimization of immunosuppression.

Valve replacement: Mechanical or tissue? - Harvard Health

Study record managers: refer to the Data Element Definitions if submitting registration or results information. Aortic valve replacement AVR therapy is obvious choice in symptomatic severe aortic stenosis AS patients, because it improves symptoms, LV function and survival. Therefore, the accurate diagnosis of the disease, determination of its severity and precise evaluation of patients' clinical status is essential. However, the treatment decisions and indication for AVR in asymptomatic patients with severe AS and normal left ventricular ejection fraction LV EF are vague and the subject of ongoing debate. The most recent European and American guidelines have class I indication for AVR in asymptomatic severe AS patients with normal LV EF only in patients already scheduled for other cardiac surgery for example by-pass surgery.

Percutaneous aortic valve replacement

Objectives: This study was designed to compare the results of aortic valve replacement in patients greater than or equal to 80 years old with those in patients 65 to 75 years old. Background: Aortic valve replacement may be potentially more complicated and require the use of more resources when performed in octogenarians rather than in younger patients. Few hard data on this possibility are available. Methods: The study group comprises all 44 patients greater than or equal to 80 years old mean age 82 years who underwent aortic valve replacement at our institution between January and July
The most common surgical procedure encountered is the Aorto-Coronary Bypass Graft ACBG for various indications such as left main coronary artery stenosis, severe triple-vessel disease, angina refractory to medical therapy, or recurrent CHF due to ischemia. Less common are removal of intracardiac tumors and LV aneurysmectomy. To perform the surgery, the patient is usually put on "pump" or cardiopulmonary bypass CPB. This involves cannulation of the right atrium and aorta and later cross-clamping of the aorta , allowing the entire cardiac output to bypass the patient's heart and lungs. Blood flow is maintained using a pump and the blood is oxygenated via a membrane oxygenator incorporated into the circuit.
