Role of Intravascular Ultrasound in Managing a Rare Case of Delayed Stent Deformity.

Delayed stent deformity is a very rare complication. We attempted to dilate the lumen within the crushed stent, but were unsuccessful even after laser atherectomy. At this point, we opted to place a new stent within the deformed old stent.

Emergent TandemHeart-ECMO for acute severe mitral regurgitation with cardiogenic shock and hypoxaemia: a case series.

Background: Acute severe mitral regurgitation (MR) associated with cardiogenic shock is a life-threatening emergency. Traditional teaching has focused on the need for emergent coronary angiography and/or intra-aortic balloon counterpulsation in preparation for emergent open-heart surgery for repair/replacement. Unfortunately, emergent open-heart surgery in patients with acute MR complicated by cardiogenic shock is associated with 25-46% perioperative mortality.
