Introduction
The benefit of implantable cardioverter-defibrillator (ICD) in patients with
non-ischemic dilated cardiomyopathy (DCM) is still an issue under
discussion. Studies examining the relationship between ventricular scar
tissue and ICD shock with cardiac magnetic resonance (CMR) are promising.
CMR studies have shown that ventricular scar tissue size and Selvester score
show a correlation. In the light of this information, this study aimed to
investigate the potential relationship between Selvester score and ICD
therapies.
Methods
The study included 48 patients who had undergone ICD implantation with a
diagnosis of DCM and who had undergone routine 6-month ICD control in
outpatient clinic controls between December 2018 and October 2019. Selvester
score and other data were compared between patients who received ICD therapy
(n=10) and those who did not (n=38).
Results
Selvester score (P<0.001) was higher in ICD therapy group. Positive
correlation was found between ICD shock therapy and Selvester score
(P=0.002, r=0.843). Selvester score was detected as an independent predictor
for ICD therapy after multiple linear regression analysis (P=0.004).
Receiver operating characteristic curve analysis showed that Selvester score
(P<0.001) was a significant predictor of ICD therapy. Selvester score
cutoff points of 5 for were calculated to estimate ICD therapy, with a
sensitivity of 100% and specifity of 81%.
Conclusion
In our study, it was found that a high Selvester score may be a predictor for
ICD therapies in patients with DCM. As an inexpensive and non-invasive
method, Selvester score can help in the decision-making in these
patients.
