RESUMO
Left ventricular pseudoaneurysm (LV-PSA) is a rare complication following cardiac surgery, let alone in the pediatric population. Other known causes of LV-PSA are trauma, percutaneous cardiac intervention, and infections. This report describes the development of LV-PSA following surgical repair of ventricular septal defect (VSD) and coarctation of aorta (CoA) in an infant.

Sinus of Valsalva aneurysm is a rare cardiac malformation that stems from incomplete fusion of the aortic media and the aortic valve annulus, a weakness that may result in rupture of the sinus, large left-to-right shunt, and severe congestive heart failure. Historically, this lesion has been repaired surgically, but percutaneous closure (PC) has emerged as a therapeutic intervention over the last 20 years. We review and contrast 34 studies detailing the PC approach with 16 studies on surgical closure (SC), together comprising a total of 877 patients who were treated for ruptured sinus of Valsalva aneurysm from 1956 to 2014. Both groups had similar sites of rupture, age distribution, and clinical symptoms at presentation. Selection bias ultimately prohibits a direct comparison between the 2 groups as patients who underwent SC often had worse aortic regurgitation and more complex associated lesions, including endocarditis, bicuspid aortic valve, tunnel-type fistulous connections, larger defect size, and multiple site of rupture. In conclusion, although SC is indicated and reserved for these more complicated patients, our review of previously published reports reveals that PC in patients who are too ill to undergo bypass, with mild or no aortic regurgitation and simple associated defects (muscular ventricular septal defects, secundum atrial septal defect, small patent ductus arteriosus), can be safe, effective, and practical.
