The patient recently underwent open heart surgery to have a prosthetic heart valve placed. His current medications include simvastatin, metoprolol and coumadin. He describes the dizziness as occurring gradually over the past few days and not succumbing to losing his balance and having a traumatic fall. He describes the dizziness as being bearable with a constant level of intensity, while also denying any nausea, vomiting or ringing in his ears. On physical exam, the patient exhibits vertical nystagmus but no horizontal or rotatory nystagmus. A Dix-Hallpike maneuver was performed, which proved to be negative. A pneumatic otoscope was also used to insufflate air into both his ear canals, which also failed to provoke an episode of vertigo with nystagmus. Which of the following is the most likely diagnosis?
