Abstract Among the 130 patients underwent percutaneous transluminal mitral valvuloplasty (PBMV) with Inoue balloon, 53 had mitral regurgitation (MR) , including 27 of post-PBMV MR,15 of unchanged MR,7 of aggravated MR, and 4 of alleviated MR.
The level of plasma calcitonin gene related peptide (CGRP) in 30 patients with mitral stenosis (MS) was measured before and after percutaneous balloon mitral valvuloplasty (PBMV).
Objective To assess the feasibility and accuracy of real-time three-dimensional echocardiographic(RT3DE) planimetry of the mitral valve area(MVA) before and after percutaneous balloon mitral valvuloplasty(PBMV).
It is shown that four characteristic regimes of change of tube shape are possible: local dilatation, collapse, flexure, and distributed auto-oscillations.
Therewith, an increase in the stomach fluid, intestinal dilatation, and an increased gallbladder tone were determined in most cases on an empty stomach, which suggested increased secretory activity.
We consider functions f(z), z ∈ D ? ?, determining the mappings w = f(z) that, at the points ζ of the domain D, have the same dilatation ratio along the three pairwise noncollinear rays issuing from ζ.
This paper presents an expansion for radial tempered distributions on ${\bf R}^n$ in terms of smooth, radial analyzing and synthesizing functions with space-frequency localization properties similar to standard wavelets.
Scales of quasi-norms are defined for the coefficients of the expansion that characterize, via Littlewood-Paley-Stein theory, when a radial distribution belongs to a Triebel-Lizorkin or Besov space.
We characterize, for finite measure spaces, those orthonormal bases with the following positivity property: if f is a non-negative function, then the partial sums in the expansion of f are non-negative.
Seventeen consecutive newborn and premature babies with critical pulmonary stenosis underwent a technically successful balloon valvuloplasty at our institution from March 1991 to February 1998.
The immature valve tissue led to recurrent, severe mitral valve incompetence and necessitated several valvuloplasty procedures and finally the implantation of a mechanical prothesis.
