Review Case ReportsRelentless pulmonary vein stenosis: a contemporary approach to a recurring problem.
Pulmonary vein (PV) stenosis is a known complication of PV isolation procedures for atrial fibrillation. Treatment can be percutaneous or surgical. We describe in this report a case of recurring PV stenosis after both surgical and percutaneous procedures, highlighting a number of novel interventional techniques. We also provide a review of literature regarding intervening in pulmonary vein occlusion.

Procedural variation in the performance of primary percutaneous coronary intervention for ST-elevation myocardial infarction: a SCAI-based survey study of US interventional cardiologists.
Great strides have been made in improving outcomes for patients with ST-elevation myocardial infarction (STEMI), predominately through initiatives focusing upon improving clinical processes "upstream" of percutaneous coronary intervention (PCI). The actual step-by-step mechanics of diagnostic angiography during STEMI and other aspects of the PCI procedure itself have received relatively little attention. ⋯ There is significant variability in the self-reported mechanics of primary PCI by US interventional cardiologists. Some of this variability (e.g., sequence of catheters, and performance of left ventriculography prior to reperfusion) is not addressed by current guidelines/consensus documents, and may have clinical implications, reflecting the balance between the desire for timely reperfusion versus a more complete assessment of patient risk.

Case ReportsThe next era of transcatheter aortic valve replacement: a case illustrating the benefit of a fully re-positionable, re-sheathable, and retrievable prosthesis.
While transcatheter aortic valve replacement (TAVR) is an accepted treatment modality in appropriately selected patients there remain modest complication rates. New TAVR devices, through novel design features, may overcome some of these complications. We present the first case of full re-sheathing and retrieval of a Lotus Valve to facilitate a change in prosthesis size.
