Beam hardening artifact reduction using dual energy computed tomography: implications for myocardial perfusion studies [PDF]

, 2015
Background: Myocardial perfusion computed tomography (CTP) using conventional single energy (SE) imaging is influenced by the presence of beam hardening artifacts (BHA), occasionally resembling perfusion defects and commonly observed at the left ...

Treatment of Coronary Perforation in a Bifurcation: Two‐Stent Strategies With Fenestrated Covered Stents

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Coronary perforations are a dreaded complication for any interventional cardiologist. The treatment of this complication is exceptionally difficult when it occurs in a coronary bifurcation. While a conservative approach or a balloon occlusion might be sufficient in some cases, additional treatment is sometimes necessary.

Computed Tomography of the Coronary Arteries

SA Heart Journal, 2017
MSCT Coronary Angiography is a fast developing non-invasive diagnostic technique that can detect a coronary stenosis. The detection of a coronary stenosis is hampered by limited image quality and by motion artefacts and extensive calcifications ...

Coronary Slow Flow and No‐Reflow During Percutaneous Coronary Intervention: Contemporary Insights Into Imaging‐Guided Prediction, Prevention, and Management

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Coronary slow flow (SF) and no‐reflow (NR) are clinically significant complications of percutaneous coronary intervention (PCI), particularly in ST‐segment elevation myocardial infarction (STEMI) and saphenous vein graft (SVG) interventions. Angiographically defined as impaired myocardial perfusion despite restored epicardial patency, SF/NR ...

Extremity Function After Transfemoral Transcatheter Aortic Valve Implantation: A TAVI XS Sub‐Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Physical decline after transcatheter aortic valve implantation (TAVI) is associated with worse outcomes. However, data on post‐TAVI extremity function are limited. This sub‐study of the TAVI XS trial aimed to assess extremity function after transfemoral TAVI, evaluate functional decline, compare outcomes between upper‐and lower ...

The “Skipping Rope” Technique: A Novel Strategy for Distal Burr Entrapment During Rotational Atherectomy

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT We describe the “skipping rope technique” for managing burr entrapment during rotational atherectomy. Sequential counterclockwise rotational force is applied to the drive shaft, generating alternative torque dynamics. This maneuver provides a safe method to disengage a stuck rotaburr, offering operators an additional strategy for this ...
