Two-stent telescoping technique for securing an atrially embolized venous stent.
Coronary sinus stenosis or atresia is a rare problem in congenital heart disease. It is sometimes associated with ventricular dysfunction. In this setting, relief of the obstruction may improve myocardial perfusion and contractility. During percutaneous stent deployment within the coronary sinus, distal embolization of the stent into the atrial chambers occurred. The patient had double inlet left ventricle, severe ventricular dysfunction, interrupted IVC, mechanical aortic valve, and a Fontan circulation. The intervention was performed as a rescue procedure prior to transplantation referral. In this report we describe use of telescoping technique, i.e., deploying the distal end of a long stent within the embolized stent while traversing its proximal end across the stenosed coronary sinus ostium. This secured the embolized stent and at the same time relieved the coronary sinus stenosis.
