Association between aortic thrombi detected using non-obstructive general angioscopy and atrial fibrillation
Atrial fibrillation (AF) is an independent risk factor for stroke and systemic embolism. Cardiogenic and aortogenic emboli are causes of stroke or systemic embolism. Non-obstructive general angioscopy (NOGA) c...

Open AccessProtective effect of the Impella on the left ventricular function after acute broad anterior wall ST elevation myocardial infarctions with cardiogenic shock: cardiovascular magnetic resonance imaging strain analysis
The clinical efficacy of the Impella for high-risk percutaneous coronary intervention (PCI) and cardiogenic shock remains under debate. We thus sought to investigate the protective effects on the heart with th...

Evaluation of the incidence, timing, and potential recovery rates of complete atrioventricular block after transcatheter aortic valve implantation: a Japanese multicenter registry study
Data on the accurate onset date and serial changes of the complete atrioventricular block (CAVB) after transcatheter aortic valve implantation (TAVI) are limited. This study aimed to assess the incidence, timi...

Importance of combined assessment of skeletal muscle mass and density by computed tomography in predicting clinical outcomes after transcatheter aortic valve replacement
Skeletal muscle mass (SMM) as calculated by computed tomography (CT) is a predictor of all-cause mortality after transcatheter aortic valve replacement (TAVR), but it remains unclear whether using CT-determine...

Effect of drug-coated balloon angioplasty on in-stent restenotic coronary lesions analyzed with optical coherence tomography and serial coronary artery angioscopy
Drug-coated balloon angioplasty (DCBA) has been recognized for its utility in preventing in-stent re-restenosis (ISR); however, imaging of the neointima immediately after treatment and during follow-up has onl...
