Ludman, MD, FRCP, FESC7; Mark A. de Belder, MD, FRCP8; Sandro Sponga, MD, PhD9; Mark Gunning, MD4; James Nolan, MD4; Pantelis Diamantouros, MD, FRCPC1; Patrick J. Teefy, MD, FRCPC1; Bob Kiaii, MD, FRCSC3,10; Michael W. A. Chu, MD, FRCSC3,10; Mamas A. Mamas, BMBCh, DPhil, MRCP4,5

Background: Preimplantation balloon aortic valvuloplasty (BAV) is considered a routine procedure during transcatheter aortic valve implantation (TAVI) to facilitate prosthesis implantation and expansion; however, it has been speculated that fewer embolic events and/or less hemodynamic instability may occur if TAVI is performed without preimplantation BAV. The aim of this study was to systematically review the clinical outcomes associated with TAVI undertaken without preimplantation BAV.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Coronary Artery Disease. The EBC TWO Study (European Bifurcation Coronary TWO). A Randomized Comparison of Provisional T-Stenting Versus a Systematic 2 Stent Culotte Strategy in Large Caliber True Bifurcations

David Hildick-Smith, MD, FRCP, Miles W. Behan, DM, FRCP, Jens F. Lassen, MD, Alaide Chieffo, MD, Thierry Lefèvre, MD, Goran Stankovic, MD, Francesco Burzotta, MD, Manuel Pan, MD, Miroslaw Ferenc, MD, Lorraine Bennett, MSc, Thomas Hovasse, MD, Mark S. Spence, MD, FRCP, Keith Oldroyd, MD, FRCP, Philippe Brunel, MD, Didier Carrie, MD, Andreas Baumbach, MD, FRCP, Michael Maeng, MD, Nicola Skipper, MSc and Yves Louvard, MD

Background: For the treatment of coronary bifurcation lesions, a provisional strategy is superior to systematic 2-stent techniques for the most bifurcation lesions. However, complex anatomies with large side branches (SBs) with significant ostial disease length are considered by expert consensus to warrant a 2-stent technique upfront. This consensus view has not been scientifically assessed.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Advances in Interventional Cardiology. Techniques and Outcomes for the Treatment of Paravalvular Leak

Mackram F. Eleid, MD, Allison K. Cabalka, MD, Joseph F. Malouf, MD, Saurabh Sanon, MBBS, Donald J. Hagler, MD and Charanjit S. Rihal, MD, MBA

Paravalvular prosthetic regurgitation is a potentially serious condition resulting from degeneration of annular tissue, affecting 6% to 15% of surgically implanted prosthetic valves and annuloplasty rings.1–3 In conditions of tissue friability from any cause, annular calcification, or infection, paravalvular defects can form and lead to varying degrees of regurgitation. Surgical factors associated with the development of paravalvular regurgitation include prostheses in the mitral position, supra-annular aortic prostheses, use of continuous sutures in the mitral position,3 and use of sutures without pledgets.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Images and Case Reports in Interventional Cardiology. Fracturing the Ring of Small Mitroflow Bioprostheses by High-Pressure Balloon Predilatation in Transcatheter Aortic Valve-in-Valve Implantation

Jens Erik Nielsen-Kudsk, MD, DMSc, Evald Høj Christiansen, MD, PhD, Christian Juhl Terkelsen, MD, DMSc, Bjarne Linde Nørgaard, MD, PhD, Kaare Troels Jensen, MD, PhD, Lars Romer Krusell, MD, Mariann Tang, MD, Kim Terp, MD, Kaj-Erik Klaaborg, MD and Henning Rud Andersen, MD, DMSc

Introduction: Early deterioration of Mitroflow aortic bioprostheses (Sorin Group Inc), particularly small sizes 19 and 21 mm, has been reported.1 Treatment of failing bioprostheses by transcatheter valve-in-valve (VIV) therapy has become an alternative to repeat surgery.2,3 However, VIV treatment is problematic with small surgical bioprostheses because of a further reduction in the effective valve orifice. One way to overcome this challenge may be to fracture the ring of the surgical valve by high-pressure balloon dilatation before implanting a larger size transcatheter valve.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Structural Heart Disease. Effect of Clinical Trial Experience on Transcatheter Aortic Valve Replacement Outcomes

Fenton H. McCarthy, MD, MS, Peter W. Groeneveld, MD, MS, Dale Kobrin, BA, Katherine M. McDermott, BS, Christopher Wirtalla, BA and Nimesh D. Desai, MD, PhD

Background: Transcatheter aortic valve replacement (TAVR) was approved by the Food and Drug Administration (FDA) in November 2011 after a collaborative technology development process involving professional medical societies, the medical device industry, and the FDA. After FDA approval, TAVR was adopted by numerous hospitals that had not participated in TAVR clinical trials. It is uncertain if outcomes at these hospitals were comparable with those at clinical trial hospitals.

JACC: CARDIOVASCULAR INTERVENTIONS. Hybrid Strategy for Long Diffuse Coronary Lesion

Sandeep Basavarajaiah, MD; Mamoon Qadir, MD

A 48-year-old man with crescendo angina exhibited a severe diffuse lesion in the left anterior descending artery (Figure 1, Online Video). The option of mammary grafting was ruled out due to poor distal target. Percutaneous coronary intervention with drug-eluting stents (DES) would result in full-metal jacket (>50 mm of overlapping stents), which poses the long-term risk of stent thrombosis, and, in addition, restenosis is often difficult to treat, with high rates of recurrence.

JACC: CARDIOVASCULAR INTERVENTIONS. Transapical Mitral Valve Implantation for the Treatment of Severe Native Mitral Valve Stenosis in a Prohibitive Surgical Risk Patient. Importance of Comprehensive Cardiac Computed Tomography Procedural Planning

Guilherme F. Attizzani, MD; Anas Fares, MD; Chor Cheung Tam, MD; Bimal Padaliya, MD; Stacey Mazzurco, RN; Kehllee L. Popovich, NP; Angela C. Davis, RN; Elizabeth Staunton, NP; Hiram G. Bezerra, MD, PhD; Alan Markowitz, MD; Daniel I. Simon, MD; Marco A. Costa, MD, PhD; Basar Sareyyupoglu, MD

A 66-year-old woman with severe mitral stenosis (mean gradient, 13.81 mm Hg; valve area, 0.8 cm2) and extensive mitral annular calcification (MAC) presented with New York Heart Association functional class IV congestive heart failure. Balloon mitral valvuloplasty was not considered due to the high Wilkins score (i.e., 12) Because of a Society of Thoracic Surgeons mortality score of 10.04% and cirrhosis (Child-Pugh B), the heart team deemed her at prohibitive surgical risk.
