An autoperfusion balloon catheter was developed to allow passive myocardial perfusion during inflation through a central lumen and multiple side holes in the shaft proximal and distal to the balloon. We report its safety and efficacy in 11 patients undergoing elective angioplasty to a single coronary lesion. Each lesion was dilated three times with the autoperfusion inflation bracketed between ...

These data hint that arteritis may be more prevalent in the frontal branch than the parietal branch. Notably, in the majority of patients who had imaging signs of temporal arteritis, abnormalities were present in one branch but not the other, at least on one side. Although neuroimaging is not equivalent to the gold standard of histopathological analysis, this result suggests that selective invo...

Cutting balloon angioplasty (CBA) is one of the adept ways of treating "in-stent restenosis." Various complications related to cutting balloon angioplasty have been reported including arterial rupture, delayed perforation and fracture of microsurgical blades. Here we report a very unusual and inadvertent extraction of a stent previously deployed in the ramus intermedius coronary branch by a cut...

BACKGROUND Severely calcified coronary lesions respond poorly to balloon angioplasty, resulting in incomplete and asymmetrical stent expansion. Therefore, adequate plaque modification prior to drug-eluting stent (DES) implantation is the key for calcified lesion treatment. This study was to evaluate the safety and efficacy of cutting balloon angioplasty for severely calcified coronary lesions. ...

A retrospective, single-center review was performed from January 2013 to June 2018. Sixty-one patients (23 children and 38 adults; aged 3-30 years) with renal artery fibromuscular dysplasia (FMD) had undergone balloon angioplasty for severe hypertension, 2 requiring bail-out stenting. Blood pressure improved in 19 (8 normalized, 11 decreased) of 21 branch FMD during follow-up. The incidence sig...

BACKGROUND Success rates for treatment of chronic total occlusion (CTO) have dramatically improved in recent years with the development of new CTO guidewires and development of new techniques such as the retrograde approach. In the antegrade approach, a guidewire is occasionally passed through a side branch despite successful wire crossing of the CTO lesion. In order to pass a wire through the ...
