Nonculprit Stenosis Evaluation Using Instantaneous Wave-Free Ratio in Patients With ST-Segment Elevation Myocardial Infarction

Clinical Case Study | By Thim T, Götberg M, Fröbert O et al.

OBJECTIVES - The aim of this study was to examine the level of agreement between acute instantaneous wave-free ratio (iFR) measured across nonculprit stenoses in patients with ST-segment elevation myocardial infarction (STEMI) and iFR measured at a staged follow-up procedure. BACKGROUND - Acute full revascularization of nonculprit stenoses in STEMI is debated and currently guided by angi...

Cost-Effectiveness of Different Durations of Dual-Antiplatelet Use After Percutaneous Coronary Intervention

Original Research | By Arbel Y, Bennell MC, Wijeysundera HC et al.

BACKGROUND - There is uncertainty regarding the optimal duration of dual-antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI). Our goal was to evaluate the cost-effectiveness of different durations of DAPT. METHODS - We created a probabilistic patient-level Markov microsimulation model to assess the discounted lifetime costs and quality-adjusted life y...

FFR-guided multivessel stenting reduces urgent revascularization compared with infarct-related artery only stenting in ST-elevation myocardial infarction: A meta-analysis of randomized controlled trials

Review Article | By Gupta A, Bajaj NS, Bhatt DL et al.

BACKGROUND - Randomized controlled trials (RCTs) have shown fractional flow reserve-guided (FFR) multivessel stenting to be superior to infarct-related artery (IRA) only stenting in patients with ST-elevation myocardial infarction (STEMI) and multivessel disease. This effect was mainly driven by a reduction in overall repeat revascularization. However, the ability to assess the effect of this strategy on...

Diagnostic performance of stress perfusion cardiac magnetic resonance for the detection of coronary artery disease: A systematic review and meta-analysis

Review Article | By Kiaos A, Tziatzios I, Karamitsos TD et al.

INTRODUCTION - The purpose of this study was to investigate the accuracy of qualitative stress perfusion cardiac magnetic resonance (CMR) to diagnose ischemia-causing lesions according to different definitions of significant coronary artery disease (CAD), and magnetic field strength. METHODS - We searched PubMed, Web of Science, and the Cochrane Library for studies evaluating diagnostic performance of qu...

Catastrophic catheter-induced coronary artery vasospasm successfully rescued using intravascular ultrasound imaging guidance

Clinical Case Study | By Kodaira M, Tabei R, Kuno T et al.

A 46-year-old man underwent coronary angiography for stable angina. He developed inferior ST-segment myocardial infarction during the angiography. Intravascular ultrasound (IVUS) findings suggested coronary vasospasm. Intracoronary administration of isosorbide dinitrate restored the coronary flow. This case illustrates the essential role IVUS imaging played in establishing the diagnosis of catheter-induced coronary vasospasm.

Fate of post-procedural malapposition of everolimus-eluting polymeric bioresorbable scaffold and everolimus-eluting cobalt chromium metallic stent in human coronary arteries: sequential assessment with optical coherence tomography in ABSORB Japan trial

Clinical Trial | By Sotomi Y, Onuma Y, Dijkstra J et al.

AIMS - The natural course of post-procedural incomplete strut apposition (ISA) after the implantation of bioresorbable scaffolds (BVS) remains unknown. The purpose of the present study was to evaluate the fate of post-procedural ISA after everolimus-eluting Absorb BVS in comparison with the second-generation everolimus-eluting cobalt chromium stent (CoCr-EES). METHODS AND RESULTS - Fate of post-proce...

Randomized comparison of stent strut coverage following angiography- or optical coherence tomography-guided percutaneous coronary intervention

Review Article | By Kim JS, Shin DH, Hong MK et al.

Intracoronary Optical Coherence Tomography 2018: Current Status and Future Directions

Review Article | By Ali ZA, Karimi Galougahi K, Maehara A et al.

The advent of intravascular imaging has been a significant advancement in visualization of coronary arteries, particularly with optical coherence tomography (OCT) that allows for high-resolution imaging of intraluminal and transmural coronary structures. Accumulating data support a clinical role for OCT in a multitude of clinical scenarios, including assessing the natural history of atherosclerosis and modulating effects of therap...

Optical coherence tomography compared with intravascular ultrasound and with angiography to guide coronary stent implantation (ILUMIEN III: OPTIMIZE PCI): a randomised controlled trial

Clinical Trial | By Ali ZA, Stone GW; ILUMIEN III: OPTIMIZE PCI Investigators.

BACKGROUND - Percutaneous coronary intervention (PCI) is most commonly guided by angiography alone. Intravascular ultrasound (IVUS) guidance has been shown to reduce major adverse cardiovascular events (MACE) after PCI, principally by resulting in a larger postprocedure lumen than with angiographic guidance. Optical coherence tomography (OCT) provides higher resolution imaging than does IVUS, although findings from some stu...

Comparison of Stent Expansion Guided by Optical Coherence Tomography Versus Intravascular Ultrasound: The ILUMIEN II Study (Observational Study of Optical Coherence Tomography [OCT] in Patients Undergoing Fractional Flow Reserve [FFR] and Percutaneous Coronary Intervention)

Original Research | By Maehara A, Ben-Yehuda O, Stone GW et al.

OBJECTIVES - The present study sought to determine whether optical coherence tomography (OCT) guidance results in a degree of stent expansion comparable to that with intravascular ultrasound (IVUS) guidance. BACKGROUND - The most important predictor of adverse outcomes (thrombosis and restenosis) after stent implantation with IVUS guidance is the degree of stent expansion achieved. ...
