Abstract
Background: Shockwave intravascular lithotripsy (IVL) coronary system is a very useful new technology for de novo severely calcified coronary artery plaques before percutaneous coronary intervention (PCI). The device uses a semi-compliant low-pressure balloon, integrated into a sterile catheter, to deliver by vaporizing fluid an expanding bubble that generates high-pressure ultrasonic energy by waves that create multiplane longitudinal micro-macro fractures in calcified plaques, which facilitate optimal stent placement and expansion, and luminal gain.
Methods: The use of Shockwave IVL coronary system in our cardiac catheterization laboratory (Cath lab) at the "Clinique Saint-Hilaire" in Rouen, France, started in March 2019, with 42 procedures performed since this date: two patients in 2019, two patients in 2020, seven patients in 2021, 23 patients in 2022, and eight patients since the beginning of 2023.
Results: We had experienced problems at the beginning of our activity for the first 11 patients (two patients in 2019, two patients in 2020, and seven patients in 2021): after less than five pulses, the shock therapy stopped. We used initially for Shockwave IVL semi-compliant low-pressure integrated balloons a mixture of 50% contrast and 50% water preparations injectable (PPI). After changing water PPI by sodium chloride physiological saline solution, we never encountered this problem again for the following 31 patients (23 patients in 2022, and eight patients since the beginning of 2023). In fact, the proper functioning of Shockwave IVL system requires ions in balloon mixture in addition to the contrast. It is thanks to the ions contained in sodium chloride physiological saline solution that the spark necessary for shocks delivery after balloon inflation is produced.
Conclusions: Water PPI or sodium chloride physiological saline solution is used in angioplasty balloons in a lot of Cath labs worldwide. It is therefore essential to disseminate in the worldwide Cath lab the obligation to put in Shockwave IVL semi-compliant low-pressure integrated balloons sodium chloride physiological saline solution, rather than water PPI for optimal performance, and the importance of Shockwave Medical reporting this to interventional cardiologists.
