Multicenter StudyStandalone balloon aortic valvuloplasty: indications and outcomes from the UK in the transcatheter valve era.
We sought to characterize UK-wide balloon aortic valvuloplasty (BAV) experience in the TAVI era. ⋯ Balloon aortic valvuloplasty offers good immediate hemodynamic efficacy at an acceptable risk of major complications. Medium-term prognosis is poor in the absence of definitive therapy.

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.

Multicenter StudyImpact of intravascular ultrasound-guided percutaneous coronary intervention on long-term clinical outcomes in a real world population.
To compare long-term clinical outcomes between intravascular ultrasound (IVUS)-guided and angiography-guided percutaneous coronary intervention (PCI) in a large "real world" registry. ⋯ IVUS-guided PCI may reduce long-term mortality when compared with conventional angiography-guided PCI. This may encourage the routine use of IVUS for PCI in patients undergoing DES implantation. © 2012 Wiley Periodicals, Inc.

Safety and effectiveness of a selective strategy for coronary artery revascularization before transcatheter aortic valve implantation.
We assessed the safety and effectiveness of a selective percutaneous revascularization strategy before TAVI in a single-center prospective registry. ⋯ In this study, the incidence of CAD is high in patients referred for TAVI. A selective, clinical based, coronary revascularization before TAVI seemed to be safe, and was associated with an outcome similar to those observed in no-CAD TAVI patients.

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.
