JACC: CARDIOVASCULAR INTERVENTIONS. The PFO Gets Blamed Again…Perhaps This Time it Is Real

Alfred A. Bove, MD, PhD

Patent foramen ovale (PFO) closure is the thing to do these days in the interventional laboratory. Closures are done for strokes, migraine headaches, and postural cyanosis, and for divers who are at risk for decompression sickness. Atrial septal defect closures are also done in the interventional laboratory, but these are known to reduce the significant left-to-right intracardiac shunt that eventually, when large enough, results in pulmonary hypertension, an Eisenmenger syndrome, and permanent lung injury.

JACC: CARDIOVASCULAR INTERVENTIONS. Covered Stents for Coarctation of the Aorta. Treating the Interventionalist or the Patient?

Ziyad M. Hijazi, MD, MPH; Damien P. Kenny, MB, MD

Interventionalists treating congenital heart lesions are constantly faced with challenging therapeutic decisions, often without randomized trials to support one approach over the other. Indeed, detailed outcome data, particularly outside of the United States, may lag behind the availability of a particular device or stent, and therefore, application of a procedure may be based on rational thought and evolving clinical experience rather than on published trials. This is certainly the case with the use of covered stents for endovascular treatment of coarctation of the aorta (CoA). Therapeutic options for native CoA in adults have evolved from surgical correction through balloon angioplasty in the early 1980s to stent implantation in the 1990s. Concerns regarding the potential for aortic wall trauma with endovascular arterioplasty evolved following reports describing high aneurysm rates (7% to 20%)

JACC: CARDIOVASCULAR INTERVENTIONS. Successful Transcatheter Aortic Valve Replacement in a Patient With a Sinus of Valsalva Aneurysm

Cara Hendry, MBChB, MD; Anthony Della Siega, MD; Imad J. Nadra, MBChB, BSc, PhD; Simon D. Robinson, MBChB, BSc, MD

Transcatheter aortic valve replacement (TAVR) is increasingly being used to treat patients with severe aortic stenosis who are either deemed to be inoperable or at prohibitive surgical risk. Both operator experience and devices have evolved over time, as have the indications for valve implantation.

JACC: CARDIOVASCULAR INTERVENTIONS. Follow-Up Improvement of Distal Vessel Diameter After Successful Chronic Total Coronary Occlusion Recanalization

Gabriele L. Gasparini, MD; Marco L. Rossi, MD; Patrizia Presbitero, MD

Chronic total occlusion (CTO) of a coronary artery promotes negative remodeling in distal reference segments by negative vascular wall remodeling and plaque growth. Restoring blood flow by recanalization potentially leads to positive vascular remodeling.

JACC: CARDIOVASCULAR INTERVENTIONS. Self-Expanding Stent Peeling Away From Overlapping Balloon-Expandable Stent Causing Late Acquired Aneurysm Formation and Stent Malapposition

Chi Yuen Chan, MBChB; Eugene B. Wu, MD; Bryan P. Yan, MBBS

A 48-year-old man underwent elective percutaneous coronary intervention of a mid–left anterior descending (LAD) artery bifurcation lesion. A dedicated bifurcation self-expanding biolimus-eluting stent (3.0 × 14 mm AXXESS, Biosensors International, Morges, Switzerland) was implanted in the mid-LAD abutting the carina of the LAD and first diagonal (D1) bifurcation. Three balloon-expandable biolimus-eluting stents (Biomatrix, Biosensors) were placed proximal to the previous stent and in the distal main branch and the D1 side branch overlapping the AXXESS stent in a Y-configuration. High-pressure post-dilation of the proximal main vessel was performed with a 3.0-mm noncompliant balloon.

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS. Early invasive versus selectively invasive strategy in patients with non-ST-segment elevation acute coronary syndrome: Impact of age

Fabio Angeli MD1,*, Paolo Verdecchia MD2, Stefano Savonitto MD3, Nuccia Morici MD4, Stefano De Servi MD5 andClaudio Cavallini MD6

Background: It is unclear whether the benefits of an early invasive strategy (EIS) in patients with non-ST-segment elevation acute coronary syndromes (NSTEACS) equally apply to younger and older individuals. Elderly patients are generally less likely to undergo EIS when compared with younger patients.

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS. Expandable sheath for transfemoral transcatheter aortic valve replacement: Procedural outcomes and complications

Bogdan Borz MD, Eric Durand MD, Phd, Christophe Tron MD, Matthieu Godin MD, Alexandre Canville MD, Camille Hauville MD, Alain Cribier MD andHélène Eltchaninoff MD*

Aims: It is currently unknown whether the expandable sheath (e-sheath) for transfemoral Edwards transcatheter aortic valve replacement (TAVR) has a lower rate of access complications than the 18/19F fixed size sheath (f-sheath). Our aim was to compare the incidence of procedural complications when using f-sheath vs. e-sheath during TAVR.
