The necrotic core component identified with VH-IVUS is related to liberation of small embolic particles during coronary stenting, which results in the poorer recovery of CFVR.

, "Melting points and thermal expansivities of proton-disordered hexagonal ice with several model potentials" (2004 A method of free energy calculation is proposed, which enables to cover a wide range of pressure and temperature. The free energies of proton-disordered hexagonal ice ͑ice Ih͒ and liquid water are calculated for the TIP4P ͓J. Chem. Phys. 79, 926 ͑1983͔͒ model and the TIP5P ͓J. Chem. Phys. 112, 8910 ͑2000͔͒ model. From the calculated free energy curves, we determine the melting point of the proton-disordered hexagonal ice at 0.1 MPa ͑atmospheric pressure͒, 50 MPa, 100 MPa, and 200 MPa. The melting temperatures at atmospheric pressure for the TIP4P ice and the TIP5P ice are found to be about T m ϭ229 K and T m ϭ268 K, respectively. The melting temperatures decrease as the pressure is increased, a feature consistent with the pressure dependence of the melting point for realistic proton-disordered hexagonal ice. We also calculate the thermal expansivity of the model ices. Negative thermal expansivity is observed at the low temperature region for the TIP4P ice, but not for the TIP5P ice at the ambient pressure.

Retrograde flow in the LAD by TTDE is a highly sensitive and specific finding that can be used to noninvasively diagnose total LAD occlusion.
