Utility of transesophageal echocardiography in interatrial septal puncture during percutaneous mitral balloon commissurotomy

Specifics of technique in percutaneous mitral commissurotomy in a case of dextrocardia and situs inversus with mitral stenosis

“…Because the use of TEE is time-consuming, requires mild sedation for the patient, and has clear technical constraints, we very seldom use it during PMC. Nonetheless, it is a fact that TEE guidance has been shown to be a useful adjunct for patients with cardiothoracic deformity or when difficulties are encountered in performing transseptal puncture [23]. Successful passage through the patent foramen ovale on the first attempt demonstrates that, in this case, these two measures resulted in safer and more accurate positioning of the transseptal catheter.…”

Transseptal puncture guided by intracardiac echocardiography during percutaneous transvenous mitral commissurotomy in patients with distorted anatomy of the fossa ovalis

“…These techniques have been limited at times by the requirement of an additional operator, interference with the sterile field, as well as inadequate images on TTE or discomfort for patients during esophageal intubation for TEE. Furthermore, a decrease in complication rate was never observed [6,7].…”

“…This can be easily achieved by shielding the gravid uterus and keeping fluoroscopy time to the minimum. Transesophageal echocardiographic guidance has also been utilized during the procedure to reduce radiation exposure [5,6].…”
