Excimer laser technology in percutaneous coronary interventions: Cardiovascular laser society's position paper
2022
Excimer Laser Coronary Atherectomy (ELCA) is a well-established therapy that emerged for the treatment of peripheral vascular atherosclerosis in the late 1980s, at a time when catheters and materials were rudimentary and associated with the most serious complications. Refinements in catheter technology and the introduction of improved laser techniques have led to their effective use for the treatment of a wide spectrum of complex coronary lesions, such as thrombotic lesions, severe calcific lesions, non-crossable or non-expandable lesions, chronic occlusions, and stent under-expansion. The gradual introduction of high-energy strategies combined with the contrast infusion technique has enabl…
Gefäßrekanalisation mit einem elektrischen Thermokauter-Katheter -In-vitro-Erfahrungen mit einem neuen Kathetersystem
1988
Recanalisation of arteriosclerotic occlusions by means of laser angioplasty, Kensey catheter and the "hot tip" catheter is undergoing early, successful clinical trials. The thermo-cautery catheter described in this paper uses the well known technique of cutting with high frequency electric currents in order to achieve vascular recanalisation. Seven attempts were made to recanalise occlusions at post mortem; four were successful, but perforation occurred in three. Histologically we found a narrow rim of carbonisation of tissues surrounded by a zone of homogenisation and a transitional zone.
