“…Therefore, that research concluded this method is effective and feasible, and may become an alternative of ventricular septal radiofrequency ablation, which is more safe than sternotomy, and also provides a reference for further HOCM animal experiments. Fu et al [27] employed ultrasound-guided transthoracic percutaneous laser ablation to perform ventricular septal laser ablation on an adult sheep's heart that is similar in size to an adult heart, and established a control group. Their results were followed-up for 1 year after ablation, and it was disclosed that ventricular septal surgery generated immediate cardiac coagulation necrosis in the ablation group.…”

For symptomatic hypertrophic obstructive cardiomyopathy (HOCM), how to effectively relieve left ventricular outflow tract obstruction is of great significance. Relying on drugs and double-chamber pacing to reduce left ventricular outflow tract pressure gradient can alleviate symptoms. Methods to reduce the thickness of inter-ventricular septum include myocardial myectomy, percutaneous transluminal septal myocardial ablation, radiofrequency catheter ablation of ventricular tachycardia, and high-intensity focused ultrasound (HIFU) ablation of the ventricular septum that were performed on animal experiments to reduce inter-ventricular septal thickness, and showed significant therapeutic effects. Ultrasound-guided percutaneous intramyocardial septal ablation, as a less invasive and more effective treatment, exhibited great application prospects in reducing the pressure gradient of left ventricular outflow tract. This article reviews the research progress of several ventricular septal ablation techniques for the treatment of HOCM.

There is a lack of evidence-based reviews on the effects of laser irradiation on blood coagulation in the literature, despite a large number of clinical trials. We therefore evaluated the available evidence on laser irradiation parameters used in coagulation of blood to optimize physical parameters. We performed a literature search for recent scientific studies indexed between 2017 and 2023 using the databases of PubMed and ScienceDirect. Articles were selected based on defined inclusion and exclusion criteria, and 78 publications in total were eventually included in this scoping review. The following were found to produce significant benefits in blood coagulation for surgical application: (1) dentistry and oral surgeries: 980 nm, 27 s, 2 W, 1502.7 W/cm2, 26.5 J, 622 J/cm2, 400 μm; (2) urogenital disorders: 532 nm, 4 s, 40 W, 10600 W/cm2, 1.3 J, 424 J/cm2, 600 μm; (3) ophthalmic disorders: 810 nm, 1 s, 1 W, 3540 W/cm2, 0.75 J, 1326 J/cm2, 100 μm; (4) embryological surgeries: 1064 nm, 10 s, 25 W, 35400 W/cm2, 262.5 J, 371000 J/cm2, 332.5 μm; (5) dermatological disorders: 1064 nm, 20 W, 2440 W/cm2, 0.1 J, 24 J/cm2, 670 μm; (6) gastrointestinal disorders: 532 nm, 3 s, 20 W, 1051 W/cm2, 120 J, 26500 J/cm2, 760 μm; (7) neurological surgeries: 2.5 s, 1.5 W, 1035 W/cm2, 2 J, 1584 J/cm2, 385 μm; (8) pulmonary disorders: 1320 nm, 5s, 35 W, 12450 W/cm2, 250 J, 65000 J/cm2, 700 μm (9) cardiovascular disorders: 1064 nm, 16.5 s, 5 W, 1980.5 W/cm2, 900 J, 760 J/cm2, 400 μm. In conclusion, our scoping review identifies that combining data from all clinically heterogeneous studies suggests that laser irradiation reflects an effective method for inducing blood coagulation in several medical fields.
