“…Thrombus is identified by the homogenous echo texture and is visualized in more than one plane. Thrombus formation can also occur acutely following BMV in patients with AF [1]. Our patient was in sinus rhythm and there was no obvious clot before the procedure.…”

We report the case of a 23-year-old female who underwent balloon mitral valvotomy for severe symptomatic mitral stenosis. Following septal puncture, the patient developed cardiac tamponade, which warranted sternotomy to suture the rent in the inferior vena cava-right atrial junction. The postoperative echocardiogram revealed nonhomogenous irregular opacities within the left atrium suggesting the possibility of thrombus formation. As the patient was in sinus rhythm and peri-procedural activated clotting time was in therapeutic range, clot formation was unlikely. A review of operative notes revealed placement of absorbable hemostatic gelatin sponge within the pericardium, which was mimicking left atrial clot. This potential pitfall has to be recognized in echocardiograms, as it will avoid inappropriate anticoagulant therapy.

“…Fresh thrombus formation has also been reported during balloon mitral valvotomy (BMV) or following it [1]. We report a case, where the gelatin sponge placed in the pericardial cavity mimicked the appearance of LA thrombus.…”
