Preliminary experience of two israeli cath labs with intravascular lithotripsy in severely calcified coronary lesions

Introduction

The lithoplasty system is made up of a semicompliant balloon catheter, connector cable, and generator. When deployed, it releases pulsatile mechanical energy that causes microfractures in the calcium.

Coronary intravascular lithotripsy(IVL) shows promise for improving the ability to optimize PCI in severely calcified lesions, with good safety and efficacy according to data from the DISRUPT CAD III trial.

We will share Bnai-zion and Meir medical center’s cath labs preliminary experience with IVL in treatment of severely calcified coronary lesions.

Material and methods

We collected data from all IVL cases that were performed in the above mentioned two centers between Nov 2019 and March 2021 to an excel sheath.

the data included clinical details; features of the stenotic lesion; IVL balloon diameter; procedure’s complications (i.e: perforation; no reflow) And Other in hospital complications.

Results and discussion

IVL use in the study period was in 9 cases in Bani-zion medical center and 4 cases in Meir medical center. First use of IVL in Israel was in Bnai-zion medical center.

The mean age of the patients was 74±10 year and the clinical presentation was NSTEMI in 76% of patients.

Of the 13 cases 12 were successfully treated; we failed to cross the lesion with IVL balloon in one case.

LAD was the target vessel in the vast majority of cases (8 of 13)

The mean length of stenotic lesion was 20.84±8.8 mm; and non of the above mentioned complications was reported.

Conclusions

These initial results from two Israeli medical centers demonstrate that the use of IVL to treat severely calcified coronary lesions has a high successful rate with no complications;

It seems to be a promising technique for improving the ability to optimize PCI in severely calcified lesions.
