Femoropopliteal Arterial Dissections Post Flex Vessel Prep and Adjunctive Angioplasty: Results of the Flex iDissection Study

Nicolas W. Shammas, MD, MS;  W. John Shammas, BS;  Susan Jones-Miller, MS;  Qais Radaideh, MD;  Gail A. Shammas, BSN, RN

Luminal gain post balloon angioplasty (PTA) is in part due to the occurrence of dissections. The depth and extent of dissections, however, can influence the short- and long-term outcomes of a procedure. Focal force and scoring balloons have been used to reduce angiographic dissections post PTA. Our aim was to examine the role of the Flex Vessel Prep system (VentureMed Group), a dynamic, microincision, non-balloon based system, prior to PTA in reducing or limiting severe dissections.

For patients needing coronary chronic total occlusion (CTO) percutaneous coronary intervention (PCI), a planned, staged intervention has been recommended by experts. Ad hoc CTO-PCI, however, occurs in practice. Our study examined the frequency, characteristics, procedural techniques, and outcomes of 2282 patients who underwent ad hoc vs planned CTO-PCI between 2012 and 2017.

Jess T. Randall, MD;  Osamah Aldoss, MD;  Asra Khan, MD;  Melissa Challman;  Gurumurthy Hiremath, MD;  Athar M. Qureshi, MD;  Manish Bansal, MD

Traditional approaches to pediatric cardiac catheterization have relied on femoral venous access. Upper-extremity venous access may enable cardiac catheterization procedures to be performed safely for diagnostic and interventional catheterizations. The objective of this multicenter study was to demonstrate the feasibility and safety of upper-extremity venous access in a pediatric cardiac catheterization laboratory.

The safety and effectiveness of the everolimus-eluting stent (EES) have been previously demonstrated. Our aim was to assess very long-term performance and outcomes of the EES in a real-world population. This single-center registry prospectively enrolled 6893 patients undergoing elective coronary intervention with the EES over a decade. Clinical follow-up was performed at 1 year and then yearly thereafter.

Shockwave Intravascular Lithotripsy of Calcified Coronary Lesions in ST-Elevation Myocardial Infarction: First-in-Man Experience

Bernard Wong, MBChB;  Seif El-Jack, MBBS;  Ruth Newcombe, DCR;  Timothy Glenie, MBChB;  Guy Armstrong, MBChB;  Aleksandar Cicovic, MBChB;  Ali Khan, MBBS

We present the first cases of Shockwave intravascular lithotripsy (S-IVL; Shockwave Medical), a novel coronary calcium modification device, being used in patients undergoing percutaneous coronary intervention for ST-elevation myocardial infarction (STEMI). The 3 presented cases include an upfront use of S-IVL in a right coronary artery, an in-stent restenosis, and a community cardiac arrest/STEMI equivalent where S-IVL was used as a bail-out technique to facilitate stent delivery in a tortuous calcified vessel.

Transcatheter Aortic Valve Replacement

Impact of Valve Over-Sizing After Transcatheter Aortic Valve Implantation With a Self-Expanding Valve: A Multislice Computed Tomography Study

Maria Drakopoulou, MD;  Konstantinos Toutouzas, MD;  Konstantinos Stathogiannis, MD;  George Latsios, MD;  Skevos Sideris, MD;  Maria Xanthopoulou, MD;  Vicky Penesopoulou, MD;  George Trantalis, MD;  Andreas Synetos, MD;  Angelos Papanikolaou, MD;  Constantina Aggeli, MD;  Manolis Vavuranakis, MD;  Dimitrios Tousoulis, MD

In transcatheter aortic valve implantation (TAVI), prosthesis oversizing prevents paravalvular regurgitation. Strategies of oversizing for self-expanding bioprostheses are not well established at present. Our study aim was to define the optimal value of valve sizing for reducing paravalvular regurgitation after TAVI.

Review

Transradial Approach to Coronary Angiography and Percutaneous Intervention in Patients With Dextrocardia

Gregory J. Sinner, MD;  Bennet George, MD;  Adrian W. Messerli, MD

Patients with dextrocardia present unique challenges in the catheterization laboratory. Variable coronary artery anatomy impacts percutaneous access, catheter selection and manipulation, and image acquisition. This is a review of all published reports of radial artery access for diagnostic and/or therapeutic coronary interventions in patients with dextrocardia. We conclude that the radial approach is safe and effective in these patients and should be used without hesitation. In addition, interventionalists should consider use of multipurpose catheters and possess an understanding of how mirror-image fluoroscopy impacts catheter manipulation.

Coronary Stent Fracture: Still a Cause of Stent Failure

Vitor Pazolini, MD;  Carlos Campos, MD, PhD;  Adriano Caixeta, MD, PhD

In the present case, multimodality images facilitated our understanding of the mechanism behind the patient’s restenosis; a technique using optical coherence tomography with three-dimensional reconstruction allowed the clear identification and extent of stent fracture as well as its subsequent optimal treatment.

Coronary Artery Thrombosis in a Neonate With Critical Aortic Stenosis

Aphrodite Tzifa, MD(Res), FRCPCH; Dimosthenis Avramidis, MD;  Konstantinos Patris, MD

To our knowledge, this is the first report describing coronary artery occlusion in a pediatric patient with critical aortic stenosis. We hypothesize that thrombus formation was due either to in situ fresh thrombus formation resulting from low cardiac output or secondary to an atrial arrhythmia in the presence of severe left ventricular diastolic dysfunction that may have occurred during the flight to our facility.

TAVR Complicated by Thoracic Aortic Perforation and Intussusception of the Right Iliac: Report of Successful Emergent Management With Endovascular Techniques

Ashleigh Long, MD, PhD and Paul Mahoney, MD

Percutaneous approaches have become routine in transcatheter aortic valve replacement (TAVR). Despite numerous advantages, vascular complications associated with percutaneous access can occur during and after TAVR, and increase morbidity and mortality significantly. Effective management of potentially catastrophic vascular complications often requires prompt recognition, diagnosis, and management by multidisciplinary teams.
