Central venous stenosis associated with pacemaker leads: short-term results of endovascular interventions.

Purpose: To determine the safety and outcomes of performing endovascular interventions across pacemaker (PM) lead-related central vein stenosis/occlusion.

Materials And Methods: Clinical and imaging records from April 2002 to August 2010 were reviewed for patients presenting with clinically significant central venous stenosis or central venous obstruction with indwelling PM leads and were evaluated to determine if any lead dysfunction or complications occurred following intervention. Thirteen patients were identified who underwent 14 interventions.

Spectrum of aortic operations in 300 patients with confirmed or suspected Marfan syndrome.

Background: Cardiovascular disease is the main cause of morbidity and mortality in patients with Marfan syndrome. Many patients with presumed Marfan syndrome do not meet current diagnostic criteria. This study reviews the surgical aspects of aortic disease in 300 patients referred with the diagnosis of Marfan syndrome.
