Current Topics The Problem of Valve Prosthesis-Patient Mismatch
نویسنده
چکیده
Valve prostheses have played an important part in the past two decades in the management of patients with valvular heart disease. However, many of the devices used in valve replacement have introduced new clinical problems. This paper deals with some of the problems associated with valve replacement, including one not previously emphasized valve prosthesis-patient mismatch, which may cause obstruction to ventricular outflow and/or inflow.

Introduction: Surgical procedures, especially total laryngectomy, have a profound adverse effect on the patient's physical, functional, as well as emotional health, and strongly decrease quality of life. Tracheoesophageal puncture is one of the most significant method that is widely performed successfully by physicians. Current valve technology enables long expiring duration; however, gen...
متن کاملIncidence and Impact of Patient-Prosthesis Mismatch in Isolated Aortic Valve Surgery
AIM The mains topics of this work are the incidence of patient-prosthesis mismatch and the influence in the early results of isolated aortic valve surgery. METHODS In 193 patients isolated aortic valve surgery was performed. The study population was divided in three subgroups: 20 patients with severe, 131 patients with moderate and 42 patients without patient-prosthesis mismatch. The indexed ...

متن کاملClinical predictors of prosthesis-patient mismatch after aortic valve replacement for aortic stenosis
OBJECTIVE We sought to ascertain predictors of Patient Prosthesis Mismatch, an independent predictor of mortality, in patients with aortic stenosis using bioprosthetic valves. METHOD We analyzed 2,107 sequential surgeries. Patient Prosthesis Mismatch was calculated using the effective orifice area of the prosthesis divided by the patient's body surface area. We defined nonsignificant, moderat...
متن کاملSeventeen-millimeter St. Jude Medical Regent valve in patients with small aortic annulus: dose moderate prosthesis-patient mismatch matter?
BACKGROUND The study was designed to evaluate the effects of moderate prosthesis-patient mismatch (defined as 0.65 cm(2)/m(2) <indexed effective orifice area ≤ 0.85 cm(2)/m(2)) on midterm outcomes after isolated aortic valve replacement with a 17-mm St. Jude Medical Regent valve in a large series of patients, and to determine if these effects are influenced by patient confounding variables. M...
