Dangas, Javier Escaned, Carlos Macaya, Josep Rodés-Cabau and Luis Nombela-Franco

Background: Currently, 2 third-generation transcatheter valves, 29-mm Sapien-3 and 34-mm Evolut-R (ER), are indicated for large sized aortic annuli. We analyzed short and 1-year performance of these valves in patients with large (area ≥575 mm2 or perimeter ≥85 mm) and extra-large (≥683 mm2 or ≥94.2 mm) aortic annuli undergoing transcatheter aortic valve replacement.

Percutaneous Interventions for Secondary Mitral Regurgitation

Mahboob Ali, Satya S. Shreenivas, David N. Pratt, Donald R. Lynch and Dean J. Kereiakes

Abstract Mitral regurgitation is frequently associated with ventricular dysfunction and carries a high mortality. Guideline-directed medical therapy, surgical mitral valve repair or replacement, and, in the setting of advanced heart failure, heart transplant and left ventricular assist devices have been the mainstay of treatment. However, rapid advancement in the field has resulted in approval of edge-to-edge mitral valve repair with the MitraClip, and there are several novel catheter-based percutaneous options in clinical trials. Percutaneous options, while promising, must be deployed in patients who are most likely to benefit, and thus, understanding the pathophysiology of specific subgroups of patients with functional mitral regurgitation (eg, disproportionate versus proportionate mitral regurgitation) is key to the success of new devices. We review the pathophysiology, percutaneous therapeutic treatment options, and ongoing clinical trials for functional mitral regurgitation.

Impact of Coronary Lesion Stability on the Benefit of Emergent Percutaneous Coronary Intervention After Sudden Cardiac Arrest

Louis Pechmajou, Eloi Marijon, Olivier Varenne, Florence Dumas, Frankie Beganton, Daniel Jost, Lionel Lamhaut, Eric Lecarpentier, Thomas Loeb, Jean-Marc Agostinucci, Georgios Sideris, Elisabeth Riant, Pierre Baudinaud, Albert Hagege, Wulfran Bougouin, Christian Spaulding, Alain Cariou, Xavier Jouven and Nicole Karam

Background: Conflicting data exist regarding the benefit of urgent coronary angiogram and percutaneous coronary intervention (PCI) after sudden cardiac arrest, particularly in the absence of ST-segment elevation. We hypothesized that the type of lesions treated (stable versus unstable) influences the benefit derived from PCI.

Comparison of Ultrathin, Bioresorbable-Polymer Sirolimus-Eluting Stents and Thin, Durable-Polymer Everolimus-Eluting Stents in Calcified or Small Vessel Lesions

Kazuhiro Dan, Hector M. Garcia-Garcia, Paul Kolm, Stephan Windecker, Shigeru Saito, David E. Kandzari and Ron Waksman

Background: The ultrathin-strut bioresorbable-polymer sirolimus-eluting stent (BP-SES) demonstrated comparable performance to durable-polymer everolimus-eluting stent (DP-EES) in randomized controlled trials. The purpose of this study was to evaluate the performance of a BP-SES compared with a DP-EES in calcified or small vessel lesions, which represent higher risk of restenosis.

Novel Panna Guide Wire Facilitates Percutaneous and Nonfluoroscopic Procedure for Atrial Septal Defect Closure

Pengxu Kong, Guangzhi Zhao, Zonggang Zhang, Weimin Zhang, Taibing Fan, Yu Han, Kunjing Pang, Shouzheng Wang, Fengwen Zhang, Weiwei Wang, Shengshou Hu and Xiangbin Pan

Background: Echo-guided percutaneous procedures have been reported reliable and advantageous. However, the learning curve is difficult for junior doctors. We aimed to evaluate the safety and efficacy of a novel guidewire (Panna wire) in percutaneous atrial septal defect closure under transthoracic echocardiography guidance only.

Intravascular Imaging-Guided Percutaneous Coronary Intervention

Evan Shlofmitz, Ziad A. Ali, Akiko Maehara, Gary S. Mintz, Richard Shlofmitz and Allen Jeremias

Abstract Despite consistent clinical data supporting the use of intravascular imaging with percutaneous coronary intervention, utilization remains low. A practical and standardized approach to incorporating intravascular imaging with percutaneous coronary intervention may overcome the barriers to utilization. This review focuses on basic image interpretation with intravascular ultrasound and optical coherence tomography and proposes an algorithmic approach to stent sizing and optimization. Incorporation of this strategic method for percutaneous coronary intervention may aid in the greater adoption of intravascular imaging for percutaneous coronary intervention.

Valve-in-Valve and Valve-in-Ring Transcatheter Mitral Valve Implantation in Young Women Contemplating Pregnancy

Adeline Fuchs, Marina Urena, Caroline Chong-Nguyen, John Kikoïne, Eric Brochet, Jérémie Abtan, Quentin Fischer, Grégory Ducrocq, Alec Vahanian, Bernard Iung and Dominique Himbert

Background: Transcatheter mitral valve implantation (TMVI) is emerging as an alternative to surgical mitral valve replacement in selected high-risk patients. Delaying definitive mechanical mitral valve replacement and the constraints of anticoagulation thanks to TMVI may be an attractive option in young women contemplating pregnancy and suffering from failure of mitral bioprosthesis or annuloplasty. The aim of the study was to evaluate the possibility, safety, and outcomes of pregnancy after TMVI in this population.

Risk of Coronary Obstruction and Feasibility of Coronary Access After Repeat Transcatheter Aortic Valve Replacement With the Self-Expanding Evolut Valve

Brian J. Forrestal, Brian C. Case, Charan Yerasi, Corey Shea, Rebecca Torguson, Cheng Zhang, Itsik Ben-Dor, Teshome Deksissa, Syed Ali, Lowell F. Satler, Christian Shults, Gaby Weissman, John C. Wang, Jaffar M. Khan, Ron Waksman and Toby Rogers

Background: The supra-annular leaflet position and tall stent frame of the self-expanding Evolut PRO or Evolut PRO+ transcatheter heart valves (THVs) may cause coronary occlusion during transcatheter aortic valve replacement (TAVR)-in-TAVR and present challenges for future coronary access. We sought to evaluate the risk of TAVR-in-TAVR with Evolut PRO or Evolut PRO+ THVs and the feasibility of future coronary access.

A Randomized Trial Evaluating Online 3-Dimensional Optical Frequency Domain Imaging–Guided Percutaneous Coronary Intervention in Bifurcation Lesions

Yoshinobu Onuma, Norihiro Kogame, Yohei Sotomi, Yosuke Miyazaki, Taku Asano, Kuniaki Takahashi, Hideyuki Kawashima, Masafumi Ono, Yuki Katagiri, Hiroyuki Kyono, Shimpei Nakatani, Takashi Muramatsu, Faisal Sharif, Yukio Ozaki, Patrick W. Serruys, Takayuki Okamura and on behalf of OPTIMUM Investigators

Background: Clinical implications of online 3-dimensional optical frequency domain imaging (3D-OFDI)-guided stenting for bifurcation lesions have not been investigated in the randomized controlled trials. The purpose of this study was to determine whether online 3D-OFDI-guided stenting is superior to angiography-guided percutaneous coronary intervention (PCI) in terms of incomplete stent apposition at the bifurcation segment.

Increasing Wait-Time Mortality for Severe Aortic Stenosis

Omar Albassam, Kayley A. Henning, Feng Qiu, Peter Cram, Tej N. Sheth, Dennis T. Ko, Graham Woodward, Peter C. Austin and Harindra C. Wijeysundera

Background: Transcatheter aortic valve replacement (TAVR) has emerged as a reasonable alternative to surgical aortic valve replacement (SAVR) for patients with severe aortic stenosis (AS). There is limited data on temporal trends in wait-times and access to care for patients with AS, irrespective of treatment modality. We sought to investigate the trends in wait-times for the treatment (either SAVR or TAVR) of AS in Ontario, Canada, and to understand the drivers of wait-list mortality and hospitalization due to heart failure.
