Proceedings ArticleDOI
An adaptive approach to abnormal heart sound segmentation
TL;DR: The method incorporates an adaptive approach for thresholding the simplicity and strength profiles to detect the timings of the sound in the presence of murmur to provide an automatic heart sounds analysis to medical professionals.
Journal ArticleDOI
Preservation of the pulmonary annulus in total correction of tetralogy of Fallot. Decreasing transannular gradients in the early follow-up period.
TL;DR: The integrity of the pulmonary annulus was preserved in 21 of 22 children consecutively subjected to total correction of tetralogy of Fallot and a similar favourable evolution of the diameters of themonary annulus and of the right pulmonary artery was observed.
Journal ArticleDOI
Long-term follow-up of elderly patients subjected to aortic valve replacement with mechanical prostheses.
TL;DR: In elderly patients older than 65 years of age who received a mechanical valve in the aortic position, implantation of a mechanical prosthesis in elderly patients safe and appropriate, but the choice must be tailored for each specific patient.
