Pa nthawi ya opaleshoni ya mphindi 45, catheter ya laser imayikidwa mu mtsempha wolakwika. Izi nthawi zambiri zimachitika pansi pa anesthesia yapafupi pogwiritsa ntchito malangizo a ultrasound. Laser imatenthetsa mkati mwa mtsempha, kuiwononga ndikupangitsa kuti ichepetse, ndikutseka. Izi zikachitika, mtsempha wotsekedwa sungathenso kunyamula magazi, kuchotsa kutupa kwa mtsempha mwa kukonza chomwe chimayambitsa vutoli. Chifukwa chakuti mitsempha iyi ndi yapamwamba, sikofunikira kuti magazi omwe atha mpweya abwerere kumtima. Ntchitoyi idzasinthidwa mwachibadwa kupita ku mitsempha yathanzi. Ndipotu, chifukwamitsempha yotupaMwachidule, zimawononga thanzi lanu lonse la kuyenda kwa magazi. Ngakhale kuti sizili pachiwopsezo cha moyo, ziyenera kuthetsedwa mavuto ena asanayambe.

Mphamvu ya laser ya 1470nm imayamwa bwino m'madzi amkati mwa selo la khoma la mitsempha ndi m'madzi omwe ali m'magazi.

Njira yosasinthika yogwiritsira ntchito photo-thermal yomwe imachitika chifukwa cha mphamvu ya laser imapangitsa kuti pakhale kutsekedwa kwathunthu kwamtsempha wochiritsidwa.

Mphamvu yochepa yomwe imafunika pogwiritsa ntchito ulusi wa laser wozungulira inachepetsa kwambiri zotsatira zoyipa poyerekeza ndi ulusi wa laser wopanda kanthu.
