Increased risk due to ventricular arrhythmias after transmyocardial laser-revascularisation? Preliminary results
Published: 1 March 1997
Keywords
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
Table
VPB/ | Couplets/ | Triplets/ | VT/ | |
|---|---|---|---|---|
24 h | 24 h | 24 h | 24 h | |
Before TMLR | 135 (16–1452) | 5 (0–235) | 0 (0–94) | 0 (0–575) |
48 h after TMLR | 301 (7–1654) | 3.5 (0–43) | 0.5 (0–26) | 0.5 (0–76) |
4 months after TMLR | 226 (12–1930) | 3 (0–91) | 0.5 (0–17) | 0 (0–13) |
