A Proposed Maneuver to Guide Transseptal Puncture Using Real-Time Three-Dimensional Transesophageal Echocardiography: Pilot Study

<div>RT3DTEE anatomically oriented view of the IAS from the RA perspective during guidance of transseptal puncture. The puncture catheter (asterisk) was introduced through the IVC into the SVC (a). Then the catheter (asterisk) was pulled inferiorly and anteriorly towards the thin part of the IAS (arrow head) “Fossa” (b and c).</div>
