BACKGROUND The influences of antiplatelet therapy discontinuation on the risk of stent thrombosis and long-term clinical outcomes after drug-eluting stent implantation have not yet been addressed adequately. METHODS AND RESULTS In an observational study in Japan, 2-year outcomes were assessed in 10 778 patients undergoing sirolimus-eluting stent(More)
The transradial approach for catheterization is becoming increasingly more popular. At present, the choice of the right or left radial artery depends on the operator's preference. We examined how the laterality influenced the effectiveness of the approach. Employing Judkins-type catheters, we performed coronary angiography in 232 patients with the left(More)
Left ventricular free wall rupture (LVFWR) is a fetal complication of acute myocardial infarction. This study was conducted to test the feasibility of percutaneous intrapericardial fibrin-glue injection therapy (PIFIT) for LVFWR after acute myocardial infarction and to assess its clinical outcome. From January 2000 to December 2004, LVFWR was confirmed by(More)
OBJECTIVE Interventional radiology tends to involve long procedures (i.e., long fluoroscopic times). Therefore, radiation protection for interventional radiology staff is an important issue. This study describes the occupational radiation dose for interventional radiology staff, especially nurses, to clarify the present annual dose level for interventional(More)

BACKGROUND The efficacy and safety of abciximab were investigated in Japanese patients undergoing percutaneous coronary intervention (PCI) for acute myocardial infarction (MI) or unstable angina. METHODS AND RESULTS The 973 patients were randomized into 3 groups: the low-dose group (L group) received bolus injection of 0.20 mg/kg followed by 12-h(More)
To investigate the underlying mechanisms of the left ventricular (LV) apical ballooning syndrome, we evaluated the functional responsiveness to dobutamine stimulation in patients with the syndrome. Over a 22-month period, 11 consecutive patients with the apical ballooning syndrome were referred to our institution. All 11 patients were women and 57 to 85(More)
BACKGROUND The use of a stent in the treatment of lesions of the superficial femoral artery (SFA) remains controversial. Although some reports have suggested that use of a nitinol stent in conjunction with aggressive medical management is effective for long SFA lesions, few long-term, large-scale studies have been done. METHODS AND RESULTS A retrospective(More)
It is important to measure the radiation dose [3-mm dose equivalent, Hp(3)] in the eye. This study was to determine the current occupational radiation eye dose of staff conducting interventional cardiology procedures, using a novel direct eye dosimeter. We measured the occupational eye dose [Hp(3)] in physicians and nurses in a catheterization laboratory(More)
The percutaneous arm approach through the radial or brachial artery for diagnostic cardiac catheterization has advantages, such as a lower incidence of access-site complications and decreased patient discomfort, particularly when smaller diameter catheters are employed. However, the pressure produced by high-flow jets of contrast material exiting from an(More)
