Rotational atherectomy (RA) has been widely used for percutaneous coronary intervention
(PCI) to severely calcified lesions. As compared to other countries, RA in Japan has …

Over the past 40 years, the safety and efficacy of percutaneous coronary intervention has
dramatically improved by overcoming several challenges. The introduction of drug-eluting …

Background: Coronary calcification inhibits stent expansion. We sought to establish an
intravascular ultrasound–derived calcium score to predict stent underexpansion. Methods …

Background Whether an eruptive or noneruptive target lesion calcified nodule (CN) portends
worse acute and long-term clinical outcomes after stenting has not been established …

Background: Optical coherence tomography (OCT) has the potential to characterize the
detailed morphology of calcified coronary plaques. This study examined the prognostic …

Background Evidence of prognostic factors for stent failure after drug-eluting stent
implantation for calcified nodules (CNs) is limited. Aims We aimed to clarify the prognostic …

The prevalence of calcification in obstructive coronary artery disease is on the rise.
Percutaneous coronary intervention of these calcified lesions is associated with increased …

Objectives. This study aimed to determine characteristics and pattern of a calcified nodule
(CN) and/or nodular calcification (NC) detected by intravascular ultrasound (IVUS) on the …

Aims: Calcified nodule (CN) has been known as the advanced stage of coronary
calcification. However, clinical outcomes following percutaneous coronary intervention (PCI) …

Abstract The Task Force on Rotational Atherectomy of the Japanese Association of
Cardiovascular Intervention and Therapeutics (CVIT) proposed the expert consensus …
