Percutaneous Mitral Balloon Valvuloplasty in a Pregnant Patient Under Guidance of Three-Dimensional Transesophageal Echocardiography and Right Atrial Mapping, without Using Fluoroscopy.

Mitral stenosis is the most common valvular pathology complicating pregnancy. Herein are reported the details of a 26-week pregnant patient with severe mitral stenosis and NYHA class 3-4 symptoms. Percutaneous mitral balloon valvuloplasty was performed under guidance of three-dimensional transesophageal echocardiography and right atrial mapping, without using fluoroscopy. Video 1: Two-dimensional transesophageal echocardiography. The four-chamber view shows limited opening of the rheumatic mitral valve. Video 2: Two-dimensional transesophageal echocardiography while the balloon is inflated. Video 3: Live/real time three-dimensional transesophageal echocardiography showing the uninflated balloon passing through the mitral valve. Video 4: Live/real time three-dimensional transesophageal echocardiography showing the inflated balloon passing through the mitral valve.
