We report the results of acetabular reconstruction using a bipolar prosthesis bearing on cancellous bone graft in 37 patients after a minimum of five years. There was a satisfactory clinical outcome in 58% when assessed by pain, range of movement and stability, with greater improvement in the pain score than of the other parameters. Radiological migration of the prosthesis was a frequent findin...
Left ventricular rupture is an infrequent but potentially fatal complication of mitral valve replacement. In spite of the fact that several methods of repair have previously been described, the mortality rate remains nearly 85%. The use of the intra-aortic balloon pump counterpulsation may increase the possibilities of success in the repair of this dreaded complication. We present here three ca...
Most surgical heart valves currently implanted are bioprosthetic tissue valves. Such valves deteriorate with time, eventually presenting with either stenosis or regurgitation. Reoperation, the current standard of care for failed valves, carries significant risk in terms of both morbidity and mortality. Implantation of a transcatheter valve inside a failed surgical valve (valve-in-valve procedur...
BACKGROUND The indications for continuous oral anticoagulant treatment, the target interval and the procedures for withdrawing treatment have changed in the last 10 years. METHODS Patients on continuous oral anticoagulant treatment at the Outpatient Anticoagulant Clinic at Umeå University Hospital in 2002 were included in a descriptive study (n = 900). 263 of those had a mechanical heart valv...
year: the lowest in the youngest age group and the highest in the oldest. Intracranial haemorrhage was seen at an unacceptable rate (0.6–0.7/year) in all age groups. Therefore, the authors conclude that the use of mechanical AVR below the age of 60 years is associated with a similar rate of intracranial bleeding as seen in older patients. This report shows the deleterious effect of over-anticoa...
OBJECTIVES Transcatheter aortic valve implantation has emerged as a valuable option to treat patients with symptomatic severe aortic stenosis, who are not being considered for surgery because of significant comorbidities. Concerns exist over treating patients who have previously undergone mitral valve surgery for possible interference between the percutaneous aortic valve and the mitral prosthe...
BACKGROUND The majority of prosthetic heart valves currently implanted are tissue valves that can be expected to degenerate with time and eventually fail. Repeat cardiac surgery to replace these valves is associated with significant morbidity and mortality. Transcatheter heart valve implantation within a failed bioprosthesis, a "valve-in-valve" procedure, may offer a less invasive alternative. ...
