Case ReportsAntegrade percutaneous valve implantation for mitral ring dysfunction, a challenging case.
The operative risk for reoperation of degenerated bioprosthetic valves or failing mitral-valve annuloplasty is higher compared with the risks for first isolated native valve repair or replacement (Astor et al., Eur Heart J 2008;29:2382-2387). In the presence of comorbidities, these risks increase exponentially. The recent introduction of transcatheter valve implantation opened new perspectives for the treatment of patients at very high surgical risk. We report a percutaneous mitral valve (MV) implantation using a transatrial approach within a MV ring using the Edwars Sapien XT valve.

The pulmonary artery pulsatility index identifies severe right ventricular dysfunction in acute inferior myocardial infarction.
Right ventricular dysfunction (RVD) is a major cause of morbidity and mortality in the setting of acute inferior wall myocardial infarction (IWMI), and early detection may improve clinical outcomes. We defined a novel hemodynamic index, the pulmonary artery pulsatility index (PAPi), and explored whether the PAPi correlates with severe RVD in acute IWMI. ⋯ The PAPi is a simple, invasive hemodynamic measure that may help identify high-risk patients with acute IWMI with severe RVD. Earlier identification of this high-risk population may improve clinical outcomes.

Percutaneous isolated pharmaco-mechanical thrombolysis-thrombectomy system for the management of acute arterial limb ischemia: 30-day results from a single-center experience.
To study the efficacy of isolated pharmaco-mechanical thrombolysis-thrombectomy (IPMT) by Trellis device (Covidien, Mansfield, MA) in managing acute limb ischemic (ALI). ⋯ Besides being the largest series of ALI patients treated with IPMT, this is the first and largest series including 14 native infrainguinal arteries. These results suggest IPMT to be a promising and safer therapeutic option in ALI, likely due to its site-specific nature and limited thrombolysis exposure time.
