Patient-prosthesis mismatch in patients with aortic valve replacement
OBJECTIVE Patient-prosthesis mismatch (PPM) may affect clinical outcomes in patients with aortic valve replacement (AVR). We retrospectively examined the PPM in patients with isolated AVR in the Japan Adult Cardiovascular Surgery Database (JACVSD). METHODS We examined all patients with isolated AVR between January 1, 2008 and December 31, 2009. The JACVSD data collection form has a total of 2...
متن کاملThe problem of valve prosthesis-patient mismatch.
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 obs...

moderate patient-prosthesis mismatch has no negative effect on patients’ functional status after aortic valve replacement with carbomedics prosthesis
conclusions moderate ppm has no negative effect on echocardiographic trans-aortic pressure gradients or the patients’ nyha functional status after avr with a carbomedics prosthesis in the mid-term follow up. results of the 66 studied patients, 39 were male and 27 were female. the mean age of the patients was 43 ± 17 with a range of 6 - 76 years. implanted sizes of the carbomedics av prosthesis ...
متن کاملSilicon synapses self-correct for both mismatch and design inhomogeneities
A neuromorphic chip with an array of neurons has connections (“synapses”) which implement a biological learning mechanism known as spike-timing-dependent plasticity (“STDP”). STDP is a homeostatic mechanism which regulates the firing rate of neurons. This mechanism is shown here to reduce variation in performance between neurons, due to both mismatch in fabrication and inhomogeneities in the el...
