Balloon aortic valvuloplasty to bridge and triage patients in the era of trans-catheter aortic valve implantation.
To describe the use of balloon aortic valvuloplasty (BAV) as a method of selecting patients for definitive aortic valve therapy. ⋯ BAV may be used to assess whether a patient might improve from definitive aortic valve treatment, particularly in those patients with left ventricular dysfunction or chronic obstructive pulmonary disease (COPD) where assessment is inconclusive or there remain concern about symptom reversibility. BAV can also be used to screen for the possibility of left main occlusion by native leaflets during TAVI.

Comparative StudyHealing responses after bifurcation stenting with the dedicated TRYTON Side-Branch Stent™ in combination with XIENCE-V™ stents: a clinical, angiography, fractional flow reserve, and optical coherence tomography study: the PYTON (Prospective evaluation of the TRYTON Side-Branch Stent™ with an additional XIENCE-v™ everolimus-eluting stent in coronary bifurcation lesions) study.
We evaluated healing responses with optical coherence tomography (OCT), and clinical and angiographic outcome after bifurcation stenting with the TRYTON Side-Branch Stent™. ⋯ The homogeneous stent strut coverage and the low LLL in the MV reflect proper healing characteristics of the TRYTON Stent in combination with the XIENCE-V™ stent. However, proximal MV edge and ostial SB restenoses together with overall clinical outcomes do not fulfill expectations of a dedicated bifurcation stent. © 2012 Wiley Periodicals, Inc.

Case ReportsMultimodality direct coronary imaging with combined near-infrared spectroscopy and intravascular ultrasound: initial US experience.
Recent studies emphasize the importance of direct intracoronary imaging techniques that provide insights regarding not only lesion architecture but also plaque composition, particularly the presence or absence of lipid-core plaque (LCP). Intracoronary near-infrared spectroscopy (NIRS) is the only validated FDA approved device for in vivo detection of LCP. A recently introduced catheter provides simultaneous NIRS spectral data coregistered with standard intravascular ultrasound (IVUS) images in a single intracoronary pullback. The present series of cases illustrates the unique data obtained by this combined NIRS-IVUS device and highlights its potential clinical applications. © 2012 Wiley Periodicals, Inc.
