Percutaneous Closure of Paravalvular Leak from a Rocking Mitral Valve in a 74-Year-Old Man at High Surgical Risk.

Dehiscence of a prosthetic heart valve or excessive rocking during the cardiac cycle is thought to preclude percutaneous paravalvular leak closure. However, surgical repair of paravalvular leak is associated with recurrent dehiscence and poor outcomes. We present the case of a symptomatic 74-year-old man in whom we performed percutaneous anchoring, involving multiple plugs and multimodal imaging, to stabilize a rocking mitral valve and close a substantial paravalvular leak caused by dehiscence.

Radioprotective strategies for interventional echocardiographers during structural heart interventions.

Objective: We investigated radioprotective strategies for the interventional echocardiographer (IE) during structural heart interventions in comparison with the interventional cardiologist (IC).

Background: Structural heart interventions are expanding in complexity with increased reliance on IE. Recent reports have demonstrated concerning exposure and higher radiation to the IE.

Comparison of Clinical and Echocardiographic Outcomes After Surgical Redo Mitral Valve Replacement and Transcatheter Mitral Valve-in-Valve Therapy.

Objectives: There are minimal data regarding clinical outcomes and echocardiographic findings after transcatheter mitral valve-in-valve replacement (TMVR) compared with redo surgical mitral valve replacement (SMVR).

Background: TMVR therapy has emerged as therapy for a degenerated bioprosthetic valve failure.

Methods: The authors retrospectively identified patients with degenerated mitral bioprostheses who underwent redo SMVR or TMVR at 3 U.

Frequency, treatment, and consequences of device loss and entrapment in contemporary percutaneous coronary interventions.

Background: Device loss and entrapment are infrequent but potentially grave complications of percutaneous coronary interventions (PCI). There are limited contemporary data on the frequency, treatment, and consequences of these complications.

Methods: We reviewed 2338 consecutive PCI cases performed between 1/2005 and 5/2010 at our institution to identify cases of device loss or entrapment.

Use of the venture wire control catheter for the treatment of coronary artery chronic total occlusions.

Background: The Venture catheter (St Jude, Minneapolis, MN) has a deflectable tip for facilitating wire steering and a stiff body. Both properties can be useful in percutaneous coronary interventions (PCI) of coronary chronic total occlusions (CTOs).

Methods: We reviewed 26 consecutive patients in whom the Venture catheter was utilized during coronary CTO PCI at our institution between May 2008 and September 2009.

Clinical presentation and angiographic characteristics of saphenous vein graft failure after stenting: insights from the SOS (stenting of saphenous vein grafts) trial.

Objectives: We sought to compare the clinical presentation and angiographic patterns of saphenous vein graft (SVG) failure after stenting with a paclitaxel-eluting stent (PES) versus a similar bare-metal stent (BMS).

Background: The mode of SVG failure after stenting has been poorly characterized.

Methods: The SOS (Stenting Of Saphenous Vein Grafts) trial enrolled 80 patients with 112 lesions in 88 SVGs who were randomized to a BMS or PES.
