ABSTRACT: Background
The study sought to investigate the clinical predictive value of quantitative flow ratio (QFR) for the long-term outcome in patients with heavily calcified lesions who underwent percutaneous coronary intervention (PCI) following rotational atherectomy (RA).Methods
In this retrospective study, 393 consecutive patients from 2009 to 2017 were enrolled. The QFR of the entire target vessel (QFRv) and the QFR of the stent plus 5 mm proximally and distally (in-segment) (QFRi) were measured. The primary endpoint was target lesion failure (TLF), including target lesion-cardiac death (TL-CD), target lesion-myocardial infarction (TL-MI), and clinically driven-target lesion revascularization (CD-TLR).Results
A total of 224 patients with 224 calcified lesions complete
