An unusual percutaneous transmitral commissurotomy: A collection of four rare occurrences!

Abstract

We are presenting an interesting case of a 30-year-old patient taken for percutaneous transvenous mitral commissurotomy (PTMC) for severe rheumatic mitral stenosis in which there was a collection of four unusual occurrences during the course of a procedure.She had recurrent generalized tonic–clonic seizures immediately after femoral sheath insertion requiring the patient to be mechanically ventilated. Subsequently, the pressure tracings recorded with catheters in the aorta and the pulmonary artery showed transient unusually high supra-systemic pulmonary artery pressure. During inflation the Accura PTMC balloon which was used to dilate the mitral valve ruptured and the procedure subsequently had to be completed using another balloon catheter. During the procedure the presence of a distended stomach due to insufflations of air during positive pressure ventilation which subsided subsequently was another unusual documentation on fluoroscopy. The final outcome of the procedure was successful.This case presents an interesting collection of unusual occurrences during a PTMC procedure which started on an unusual note but ended on a successful one. Careful assessment and appropriate management of complications can lead to successful outcome of procedures as in our case.
