Review Meta AnalysisA meta-analysis of transcatheter closure of patent foramen ovale versus medical therapy for prevention of recurrent thromboembolic events in patients with cryptogenic cerebrovascular events.
We sought to perform a meta-analysis of randomized controlled trials (RCTs) comparing percutaneous patent-foramen-ovale (PFO) closure with medical therapy for preventing recurrent thromboembolic events after cryptogenic stroke. ⋯ In this meta-analysis of contemporary RCTs, successful transcatheter closure of PFO might be more effective than medical therapy alone for the prevention of recurrent thromboembolic events.

Comparative StudyThree-dimensional multidetector computed tomography versus conventional 2-dimensional transesophageal echocardiography for annular sizing in transcatheter aortic valve replacement: Influence on postprocedural paravalvular aortic regurgitation.
In transcatheter aortic valve replacement (TAVR), the influence of aortic annular assessment with either multidetector computed tomography (MDCT) or conventional transesophageal echocardiography (TEE) on the incidence of postprocedural paravalvular aortic regurgitation (PAR) was evaluated. ⋯ MDCT-based annular sizing in TAVR significantly reduces postprocedural PAR, and THV oversizing appears pivotal in this aspect. Further delineation of the optimal degree of THV oversizing is needed.

Case ReportsTranscatheter treatment of SVC syndrome from histoplasmosis-related mediastinal fibrosis in a 9-year old male.
We report a case of mediastinal fibrosis secondary to histoplasmosis in a 9-year old male, who presented with superior vena cava syndrome. He was successfully treated by percutaneous superior vena cava stent placement in the outpatient cardiac catheterization laboratory.

Randomized Controlled TrialEffect of remote ischemic preconditioning on serum troponin T level following elective percutaneous coronary intervention.
Elective percutaneous coronary intervention (PCI) is associated with myocardial necrosis, as evidenced by troponin release, in approximately one-third of cases. This is known to be linked with subsequent cardiovascular events. This study assessed the ability of remote ischemic preconditioning (RIPC) to attenuate cardiac troponin T (cTnT) release after elective PCI. ⋯ The use of RIPC immediately prior to PCI attenuates procedure-related cTnT release and does not affect occurrence of post procedural MI, CKMB, or CRP levels.

Case ReportsEndovascular stenting for treatment of a left internal mammary artery pseudoaneurysm following redo-sternotomy: a case report.
An 85-year-old gentlemen with a history of previous triple vessel coronary bypass grafting presented with severe aortic stenosis and occlusion of the previous saphenous vein grafts but with patent left internal mammary artery (LIMA)-left anterior descending. The patient underwent uncomplicated repeat sternotomy and aortic valve replacement with repeated coronary bypass. On post-operative day 21 the patient was successfully resuscitated from a pulseless electrical activity (PEA) arrest, and was found to have a 1-cm pseudoaneurysm of the left internal mammary artery at the level of sternomanubrial junction with associated hemothorax. ⋯ The defect was successfully repaired by endovascular implant of a 3.5 mm × 12 mm Graft Master covered stent (Abbott Vascular). The patient recovered well from the procedure without further complications and was discharged after a total of 48 days of hospital stay. Our experience confirms the feasibility of repairing post-operative pseudoaneurysm in the internal mammary artery by endovascular stent grafting, thereby avoiding the risks and complications of a repeat open chest procedure.
