Disease relevance of Angioplasty, Balloon, Laser-Assisted

• Direct holmium laser-assisted balloon angioplasty in acute myocardial infarction [1].

High impact information on Angioplasty, Balloon, Laser-Assisted

• Modulation by beta-aminopropionitrile of vessel luminal narrowing and structural abnormalities in arterial wall collagen in a rabbit model of conventional balloon angioplasty versus laser balloon angioplasty [2].
• Using a xenon chloride (308 nm) excimer laser generator and 1.5 to 1.75 mm catheters, excimer laser angioplasty was attempted at 135 ns pulse width, 25 to 40 Hz repetition rate, 2 to 5 s laser delivery time and 30 to 60 mJ/mm2 energy fluence [3].
• Coronary excimer laser angioplasty: reduced complications and indium-111 platelet accumulation compared with thermal laser angioplasty [4].
• Hepatic inferior vena cava obstructions: clinical results of treatment with percutaneous transluminal laser-assisted angioplasty [5].
• Laser balloon angioplasty combined with local intracoronary heparin therapy: immediate and short-term follow-up results [6].

Biological context of Angioplasty, Balloon, Laser-Assisted

• To better define the vessel response to laser balloon angioplasty, its effects on luminal diameter, Indium-111 labelled platelet deposition, and histology were studied in 10 atherosclerotic rabbits [7].

Anatomical context of Angioplasty, Balloon, Laser-Assisted

• Three clinical trials are now being conducted to explore potential applications, including the LARS trial of excimer laser versus balloon angioplasty to treat in-stent restenosis, the PELA trial of excimer laser angioplasty in occluded superficial femoral artery disease, and the LACI trial of excimer laser angioplasty in limb-threatening ischaemia [8].

Associations of Angioplasty, Balloon, Laser-Assisted with chemical compounds

• CONCLUSION: Holmium laser-assisted balloon angioplasty appears promising in the treatment of acute ischemic syndromes and thrombotic coronary lesions [9].
• To limit the thickness of the coagulation layer in laser balloon angioplasty, we used a carbon monoxide (CO) laser, which has high tissue absorption, as a therapy laser source instead of a Nd: YAG laser [10].
• Percutaneous transluminal laser angioplasty. Progress over the past two years [11].

Gene context of Angioplasty, Balloon, Laser-Assisted

• Percutaneous transluminal laser angioplasty has become an accepted method of treatment of peripheral arterial occlusive disease [12].
• Laser balloon angioplasty: a review of the technique and clinical applications. LBA Study Group [13].
• Nineteen of the patients underwent a conventional recanalization (PTA; mean length of occlusion 4.4 +/- 4.1 cm), and 25 underwent percutaneous laser-assisted angioplasty (PLA; mean length of occlusion 10.1 +/- 6.7 cm) [14].

Analytical, diagnostic and therapeutic context of Angioplasty, Balloon, Laser-Assisted

• In the 11 patients treated with elective laser balloon angioplasty (reference diameter 2.94 +/- 0.22 mm), the minimal luminal diameter increased from 0.45 +/- 0.25 to 1.85 +/- 0.46 mm after conventional angioplasty and to 2.44 +/- 0.29 mm after laser balloon angioplasty (p less than 0.001) [15].
• Indium-111-labelled platelet scintigraphy was performed in two patients after laser-assisted balloon angioplasty [16].
