Stent Crushing as a Novel Therapeutic Option In-Stent Entrapment

Stent Entrapment is a rare complication of Percutaneous Coronary Intervention if left in situ may cause intracoronary or systemic embolization, thrombus formation, emergent coronary artery bypass graft surgery, or death. We here present a case of 2 unexpanded Drug eluting stent entrapment during the procedure leading to hemodynamic instability and Its treatment using stent crushing as a life-saving procedure.

Successful Percutaneous Balloon Dilatation of Membranous Sub-aortic Stenosis in a 22 Year Old Pregnant Patient

Congenital obstruction of the left ventricular outflow tract comprises a heterogeneous group of disorders, with obstruction potentially occurring below, above, or at the level of the aortic valve. Subvalvular stenosis is the second most common type of left ventricular outflow tract obstruction, of which discrete membranous type is the most common. Although surgical resection of the subaortic membrane is the treatment of choice in discrete membranous subaortic stenosis, in selected patients with isolated membranous subaortic stenosis, without significant aortic insufficiency, percutaneous balloon tearing of the membrane results in reduction in the degree of left ventricular outflow tract obstruction and symptomatic relief. We report a case of 22 year old pregnant patient admitted with NYHA class III breathlessness, found to have discrete membranous subaortic stenosis. Balloon aortic valvuloplasty was performed in the patient with good result. Patient underwent normal vaginal delivery at 38 weeks. Both mother and newborn were asymptomatic. Patient is asymptomatic on subsequent follow-ups.
