Is the Evaluation Sufficient? Interpretation on the Cardiac Inhomogeneity Without Considering the Transmural Dispersion
The authors opine on a previous study by Mirbolouk et al (J Invasive Cardiol. 2014;26(9):444-450) and recommend the addition of transmural dispersion data to the study to reveal the effects of revascularization procedures on electrical heterogeneity…
Interventional Cardiology: Reflections on My Career Choice at 10 Years
Dr Naidu offers his thoughts on the state of Interventional Cardiology after a decade in practice.
Intravascular-Ultrasound Assisted Localization and Revascularization of an Ostial Chronic Total Occlusion: Utility of Near-Field and Far-Field Imaging
We demonstrate the utility of intravascular ultrasound imaging in the localization of an ambiguous or “stump-less” ostial CTO in addition to providing real-time far-field imaging, which is helpful in tracking wire progress through the occluded segmen…
Percutaneous Transcatheter Balloon Valvuloplasty for Bioprosthetic Tricuspid Valve Stenosis in a patient With Orthotopic Heart Transplant
A 47-year-old man with history of familial cardiomyopathy and orthotopic heart transplant at the age of 34 years presented severe tricuspid stenosis (TS) with a mean transvalvular gradient of 10 mm Hg. To the best of our knowledge, this is the first…
Adoption of the Hybrid CTO Approach by a Single Non-CTO Operator: Procedural and Clinical Outcomes
This study tested the feasibility of adopting the “hybrid” approach by a single operator without prior experience in CTO-PCI. The authors conclude that the “hybrid” approach to CTO-PCI can be successfully adopted by a single operator with excellent e…
Commentary: Intraaortic Balloon Pump Versus Percutaneous Ventricular Assist for the High-Risk Patient: Keep it Simple Except When You Can't
In order to put the pVAD analysis of Shah et al into clinical perspective, Drs Shields and Goldberg review the definitions of “high-risk PCI,” the mechanism of action of support devices for PCI patients, and comment on the results of trials comparing…
Clinical and Economic Effectiveness of Percutaneous Ventricular Assist Devices for High-Risk Patients Undergoing Percutaneous Coronary Intervention
This study conducted a review of all comparative randomized control trials of the pVADS (Impella and TandemHeart) vs IABP for patients undergoing high-risk percutaneous coronary intervention (PCI).
Safety, Feasibility, and Long-Term Results of Percutaneous Closure of Atrial Septal Defects Using the Amplatzer Septal Occluder Without Periprocedural Echocardiography
Percutaneous closure of atrial septal defects (ASDs) is usually performed using simultaneous fluoroscopic and transthoracic, transesophageal, or intracardiac echocardiographic guidance. This study sought to assess the safety and efficacy of percutane…
Comparison of Diabetic and Non-Diabetic Patients Undergoing Endovascular Revascularization for Peripheral Arterial Disease
This study assessed the clinical outcomes of diabetic versus non-diabetic patients with peripheral arterial disease who underwent peripheral transluminal angioplasty (PTA). Diabetic patients were found to more frequently present with critical limb is…
A Prospective, Randomized, Pivotal Trial of a Novel Extravascular Collagen-Based Closure Device Compared to Manual Compression in Diagnostic and Interventional Patients
The RESPECT trial was a multicenter, randomized comparison that evaluates the safety/efficacy of the new Vascade extravascular closure system (Cardiva Medical, Inc) in diagnostic and interventional procedures. Compared to manual compression, Vascade…
