The impact of changes in B-type natriuretic peptide levels on prognosis after transcatheter aortic valve implantation
AbstractHigher B-type natriuretic peptide (BNP) levels at discharge predict higher cardiovascular events in transcatheter aortic valve implantation (TAVI) patients. However, it is not known whether the reduction in BNP levels effectively predicts prognosis. The purpose was to examine the predictive power of percentage changes in BNP levels for all-cause death and hospitalization of heart failure (HF) after TAVI in severe aortic stenosis (AS) patients. We analyzed 70 severe AS patients treated with TAVI who had a record of BNP  >  200 pg/mL. Receiver operating characteristics (ROC) curves analysis for ...

Utility of computed tomography in cases of aortic valve stenosis before and after transcatheter aortic valve implantation
AbstractTrans-catheter aortic valve implantation (TAVI) has been recognized as a useful treatment for patients with severe aortic valve stenosis, particularly those with moderate to high risks of open heart surgery. A thorough evaluation of the aortic valve complex, including the size or presence of calcifications of the leaflets and annulus, is important for the selection of appropriate candidates, artificial valve types and approach. Echocardiography is useful for the precise evaluation of aortic valve stenosis severity and aortic valve complex morphology, but it is not useful to evaluate three-dimensional aortic valve a...

Significance of echocardiographic evaluation for transcatheter aortic valve implantation
AbstractTranscatheter aortic valve implantation (TAVI) is widely accepted as an alternative to surgical aortic valve replacement (SAVR) for the treatment of severe aortic stenosis (AS). Existing scientific evidence demonstrates that TAVI is superior to SAVR, and it is expected that indications for the clinical applications of TAVI will be expanded in the future. Echocardiography plays a key role in perioperative assessment of patients undergoing TAVI. Preprocedural echocardiographic evaluation is important to determine the severity of AS in addition to patients ’ anatomical suitability for TAVI. Furthermore, echocard...

Acute and mid-term outcomes of drug-coated balloon following rotational atherectomy
AbstractRotational atherectomy (RA) is effective for reducing calcified plaque volume as part of percutaneous coronary intervention (PCI). Most lesions are then treated by stenting, but we often observe in-stent restenosis (ISR) due to an under-expanded stent associated with severe calcification, a condition that is particularly challenging to treat. It is unknown if drug-coated balloon (DCB) application following RA can be used as a “stentless” treatment strategy for calcified lesions. The aim of this study is to assess the acute and mid-term efficacy of DCB following RA (RA + DCB) at our institu...

Peak systolic velocity ratio derived from quantitative vessel analysis for restenosis after femoropopliteal intervention: a multidisciplinary review from Endovascular Asia
AbstractWith technological improvements in the endovascular armamentarium, there have been tremendous advances in catheter-based femoropopliteal artery intervention during the last decade. However, standardization of the methodology for assessing outcomes has been underappreciated, and unvalidated peak systolic velocity ratios (PSVRs) of 2.0, 2.4, and 2.5 on duplex ultrasonography have been arbitrarily but routinely used for assessing restenosis. Quantitative vessel analysis (QVA) is a widely accepted method to identify restenosis in a broad spectrum of cardiovascular interventions, and PSVR needs to be validated by QVA. T...

Triple, dual, and single antithrombotic therapy for patients with atrial fibrillation undergoing percutaneous coronary intervention
AbstractIn patients with atrial fibrillation (AF), concomitant coronary artery disease is often present, and vice versa. Although both AF and coronary artery disease need antithrombotic therapy to reduce ischemic events, optimal antithrombotic regimens for patients with AF undergoing percutaneous coronary intervention (PCI) remain unclear. Triple therapy, a combination of oral anticoagulant plus dual antiplatelet therapy with aspirin and P2Y12 inhibitor, has been used for patients with AF undergoing PCI as an initial antithrombotic strategy in the recent decade. However, triple therapy is well-known to induce severe bleedi...
