Transcatheter mitral valve-in-valve (TMVIV) or valve-in-ring (TMVIR) replacement has shown early promise in patients deemed poor surgical candidates as a less invasive alternative to conventional reoperative mitral valve (MV) replacement. ⋯ TMVIV and TMVIR can be safe and effective in a patient population considered at prohibitive risk for conventional surgery. These procedures can be performed efficiently in a hybrid operating room, with relatively short procedural times and high rates of early extubation. Procedural complications, mortality, and readmission rates for CHF at 30 days, 180 days, and 1 year were very low in this high-risk cohort.

Randomized Controlled Trial Multicenter Study
Long-Term Outcomes of Different Two-Stent Techniques With Second-Generation Drug-Eluting Stents for Unprotected Left Main Bifurcation Disease: Insights From the FAILS-2 Study.
To investigate the long-term clinical outcomes of second-generation drug-eluting stent (2G-DES) implantation for the treatment of complex unprotected left main coronary artery (ULMCA) bifurcation lesions with different two-stent techniques. ⋯ T-stenting, mini-crush, and culotte techniques using 2G-DES for ULMCA bifurcation disease showed similar clinical outcomes at long-term follow-up. MACE rates were mainly driven by in-stent restenosis at the circumflex ostium.

Axillary artery intraaortic balloon pump (IABP) placement enables those awaiting transplant to ambulate and get stronger, but motion increases risk of IABP migration. The management of a migrated pump in a 44-year-old man with heart failure is described.

Radiation dose was compared between two modern imaging systems with different x-ray tube technology (Megalix vs Gigalix) and detector type (amorphous vs crystalline silicon) at the same institution. ⋯ The Gigalix tube and crystalline Si detector decrease radiation dose by 50%-60% for fluoroscopy and cine acquisition in pediatric patients.
