Subaortic stenosis usually occurs without a previous heart operation, however, it can occur after heart surgery as well, with a condition known as a secondary subaortic stenosis (SSS). SSS has been reported after surgical repair of several congenital heart defects. There are only a few recorded cases of SSS after repair of ventricular septal defect (VSD). Here we report a rare case of SSS that ...

In this paper, a relation for finding type-II discrete sine transform (DST) from type-I discrete Hartley transform (DHT) has been derived. The transform length N is taken as even. Using this relation, the (N 1) output components of DST can be realized from DHT. The DHT is one of the transforms used for converting data in time domain into frequency domain using only real values.

Discrete subaortic membrane is a rare cause of left ventricular outflow tract obstruction. The Mmode and two-dimensional transthoracic echocardiographic features of discrete subaortic membrane have been described previously. In this study transesophageal e.chocardiography (TEE) have been performed in 8 patients. previously diagnosed by transthoracic echocardiography to have discrete subaortic m...

There is recent interest in using discrete choice experiments (DCEs) to derive health state utility values, and results can differ from time tradeoff (TTO). Clearly, DCE is "choice based," whereas TTO is generally considered a "matching" task. We explore whether procedural adaptations to the TTO, which make the method more closely resemble a DCE, make TTO and choice converge. In particular, we ...

X-ray absorption near edge structure (XANES) measurements at the C, N, and Fe K absorption edges were performed for iron(III)-tetraphenylporphyrin (FeTPP), iron(III)-tetrakis(p-carboxyphenyl)porphyrin (FeTCPP), and iron(III)-tetrakis(p-sulfonatophenyl)porphyrin (FeTSPP). The spectral shapes differ in the Fe K XANES, but not in C and N K XANES among FeTPP, FeTCPP, and FeTSPP. Crosschecks of XANE...
