BACKGROUND - The difference in intraluminal intensity of blood speckle (IBS) on integrated backscatter-intravascular ultrasound (IB-IVUS) across the coronary artery stenosis (i.e., ΔIBS) has been reported to negatively correlate with fractional flow reserve. Fractional flow reserve after coronary stenting is known as a predictor of target vessel revascularization (TVR). However, the relation between ΔIBS and TVR is unclear. ...
Long-term clinical outcomes after treatment of stent restenosis with two drug-coated balloons
Original Research | By Schröder J, Vogt F, Burgmaier M et al.
BACKGROUND - Treatment of in-stent restenosis (ISR) is still a clinical challenge in interventional cardiology. Paclitaxel-coated balloons (PCBs) are an attractive therapeutic option for ISR. There are several different types of PCBs available for percutaneous coronary intervention, but to date, comparative data between different types of PCBs for the treatment of ISR are scarce. PATIENTS AND METHOD...
Prognostic Value of Intravascular Ultrasound in Patients With Coronary Artery Disease
Clinical Trial | By AS Schuurman, MM Vroegindewey, I Kardys et al.
BACKGROUND - It has been shown that intravascular ultrasound (IVUS) and radiofrequency (RF-)IVUS can detect high-risk coronary plaque characteristics. OBJECTIVES - The authors studied the long-term prognostic value of (RF-)IVUS-derived plaque characteristics in patients with coronary artery disease (CAD) undergoing coronary angiography. METHODS - Fr...

What the article teaches The article highlights the competency of high volume operators across institutions that despite moving to lower volume centers retain their good clinical outcomes. How it will impact practice Although current U.S. based guidelines suggest a volume of at least 50 PCIs annually for operators to retain clinical competency thi...

OBJECTIVES - The aim of this quasi-experimental study was to examine whether high-volume percutaneous coronary intervention (PCI) operators still maintain high volume and quality of outcomes when they moved to lower volume hospitals. BACKGROUND - Systematic reviews have indicated that high-volume PCI operators and hospitals have higher quality outcomes. However, little is known on whether high PCI v...

BACKGROUND - Clinical outcomes following coronary computed tomography–derived fractional flow reserve (FFRCT) testing in clinical practice are unknown. OBJECTIVES - This study sought to assess real-world clinical outcomes following a diagnostic strategy including first-line coronary computed tomography angiography (CTA) with selective FFRCT testing. METHODS - Th...

BACKGROUND - Current guidelines recommend intravascular ultrasound (IVUS) or fractional flow reserve (FFR) to decide upon ambiguous left main (LM) disease. However, no study has compared the safety of LM revascularization deferral based on FFR or IVUS. METHODS - MEDLINE/PubMed was systematically screened for studies reporting on deferred treatment of angiographically ambiguous LM...

Intravascular ultrasound (IVUS) offers tomographic images of the coronary artery, helping physicians to refine drug-eluting stent (DES) implantation in angiographically complex lesions. However, controversy exists regarding whether the routine use of IVUS in short-length lesions leads to improved clinical outcomes after DES implantation. Therefore, we evaluated the usefulness of IVUS in predicting major adverse cardiac ...
