Temporal changes of incomplete stent apposition during early phase after everolimus-eluting stent implantation: serial optical coherence tomography analyses at 2-week and 4-month.

The healing process of acute incomplete stent apposition (ISA) in the early phase after stent implantation has not been well understood. We evaluated the temporal changes of ISA during the early phase after everolimus-eluting stent (EES) implantation using serial optical coherence tomography (OCT) analyses. Serial OCT examinations were performed immediately post-stenting and 2-week and 4-month after EES implantation for patients with ST-segment elevation myocardial infarction.

Impact of vascular access site on procedural time of endomyocardial biopsy.

Endomyocardial biopsy (EMB) is widely used for the diagnosis of unexplained ventricular dysfunction and for assessment of cardiac allograft rejection. But, the impact of vascular access site on procedural time of EMB is not well-known. From February 2014 to May 2016, consecutive patients requiring EMB were prospectively enrolled in this study.

Impact of Continuous Administration of Tolvaptan on Preventing Medium-Term Worsening Renal Function and Long-Term Adverse Events in Heart Failure Patients with Chronic Kidney Disease.

Tolvaptan (TLV) has an inhibiting effect for worsening renal function (WRF) in acute decompensated heart failure (HF) patients. However, there are limited data regarding the effect of continuous TLV administration on medium-term WRF.This was a retrospective observational study in hospitalized HF patients with chronic kidney disease (CKD).
