Introduction

Transmyocardial laser-revascularisation (TMLR) is a new and promising method for the treatment of angina pectoris in patients with no other therapeutic options. We investigated the incidence of ventricular arrhythmias (VA) before, immediately after and 4 months after TMLR.

Methods

In this ongoing, 24 h study Holter monitors were applied immediately before, 48 h after and 4 months after TMLR-surgery and analysed using Hellige-Marquette 4000 software. We registered ventricular premature beats mean (VPB), ventricular couplets, triplets and ventricular tachycardias (VT).

Results

We included 16 patients so far, mean age 64.8 (± 7.9) bypass surgery previous to the TMLR. Mean echocardiographic ejection fraction was 45%. The table summarizes the results of our patients, values are given as median and minimum/maximum.

Conclusion

Our preliminary data suggest a temporary increase of ventricular premature beats in the early phase after TMLR, but no increase of ventricular tachycardias.
