Laser Angioplasty Technology Context:A private hospital in Chennai has introduced Excimer Laser Coronary Atherectomy (ELCA) technology for advanced heart treatment. The technology helps treat complex coronary artery blockages that are difficult to manage with normal angioplasty methods. About Laser Angioplasty (ELCA) Full Form: Excimer Laser Coronary Atherectomy (ELCA). It is a minimally invasive cardiac procedure using laser energy to remove blockages inside heart arteries. Uses ultraviolet laser pulses to break down and remove plaque and clots. The procedure is performed through a thin catheter inserted through the wrist or groin artery.
