Troubleshooting for Epileptiform Activity during Percutaneous Transvenous Mitral Commisurotomy

Percutaneous transvenous mitral commisurotomy (PTMC) is a frequently used minimally invasive procedure for patients with symptomatic mitral stenosis. However, it is not without complications. Few complications which are distinctive to the procedure are thromboembolism, left-to-right shunts, mitral regurgitation, cardiac tamponade and complete heart block. We present the case of a 32-year-old female patient scheduled for a PTMC, who had multiple complications during the procedure. She developed cardiac tamponade for which pericardiocentesis and autotransfusion was done. Subsequently she exhibited epileptiform activity for which there was a diagnostic dilemma due to the presence of multiple confounding factors. However, she had a complete recovery without any residual sequelae at the time of discharge.
