We analyzed 14 cases of new lesions inside implanted bare-metal stents. In every case, there was no angiographic restenosis within 3 years, but a new lesion was observed inside a stented segment at long-term follow-up (>5 years). Fourteen cases were evaluated: 9 with Wiktor stents, 2 with Palmaz-Schatz stents, and 3 with ACS Multilink stents. The interval(More)
BACKGROUND The purpose of this study was to evaluate the long-term safety of the Igaki-Tamai stent, the first-in-human fully biodegradable coronary stent made of poly-l-lactic acid. METHODS AND RESULTS Between September 1998 and April 2000, 50 patients with 63 lesions were treated electively with 84 Igaki-Tamai stents. Overall clinical follow-up (>10(More)

If the intra-atrial conduction time of a focal tachycardia is prolonged and exceeds the tachycardia cycle length, isochronal electroanatomical maps may be confusing by not showing the classical centrifugal pattern of focal activation. In addressing the hypothesis that by mapping post pacing intervals (PPI), the shortest PPI (ideally identical to tachycardia(More)
An 83-year-old male with a history of angina pectoris presented with massive intracranial hemorrhage in June 2011, and he died 2 days after admission. Previously, he was included in the first in-human feasibility study of biodegradable poly-l-lactic acid (PLLA) coronary stents: the Igaki-Tamai stents (Kyoto Medical Planning Co Ltd, Kyoto, Japan). To assess(More)
A 35-year-old woman presented to the emergency room with a 2-month history of general malaise and anasarca. The chest x-ray showed cardiomegaly, and transthoracic echocardiography revealed massive pericardial effusion leading to cardiac tamponade (Figure 1A and 1B). Immediately, 1400 mL pericardial effusion (yellow exudate) was removed by needle(More)
Ebstein's anomaly is highly associated with atrioventricular reciprocating tachycardia (AVRT) due to an atrioventricular accessory pathway (AP). This case report describes a case of a 30-year-old man with Ebstein's anomaly who had been suffering from recurrent palpitation caused by AVRT due to the right-sided AP. Conventional mapping technique failed to(More)
A 17-year-old woman was found to have ectopic atrial tachycardia by her physician. Echocardiography and cardiac catheterization revealed findings resembling dilated cardiomyopathy at the time of initial presentation. The tachycardia was controlled with atenolol only at a dose of 50 mg/day. However, at the age of 22, the presence of ectopic atrial(More)
