Abstract
Aim
The aim of this study was to investigate the frequency of mitral valve prolapse (MVP) in patients with supraventricular tachycardia (SVT) who were diagnosed by intracardiac electrophysiological study (EPS).
Method
The study was a retrospective cohort of 378 adult patients (128 males and 250 females, 17 to 63 years) admitted with EPS. We included 267 SVT patients (58.4 % (n = 156) atria-ventricular nodal reentrant tachycardia (AVNRT), 30 % (n = 80) atria-ventricular reentrant tachycardia (AVRT), 6.4 % (n = 17) atrial tachycardia (AT), and 5.2 % (n = 14) other). MVP prevalence was compared in individuals with SVT.
Results
MVP prevalence was found 27.7 % (n = 74) in patients with SVT. In subgroup analyses, there was a significant difference between AVRT and others about MVP prevalence (AVRT 52.7 % n = 39, AVNRT 33.8 % n = 25, AT 9.5 % n = 7, and others 4.1 % n = 3; p < 0.005). Also, there was a significant difference between females and males (75.7 % (n = 56); 24.3 % (n = 18); p < 0.05). There was a significant negative correlation between age and MVP just in female group (r = −0.116, p = 0.024).
Conclusion
It was demonstrated in our study that AVRT and female sex may be related to MVP in SVT patients. It was dedicated from these results that the existence of arrhythmia should be focused on young female subjects with MVP more than the others.

This paper reports on the prevalence of mitral valve prolapse among patients with supraventricular tachycardia in a retrospective cohort of patients who underwent electrophysiology studies. Over 25 % of patients with supraventricular tachycardia had concomitant mitral valve prolapse. This study also reports on subgroups of patients with mitral valve prolapse (severity and age, gender of patients) and how this affects the findings.
