  ABSTRACT: Persistent left superior vena cava is known to be associated with cor triatriatum. The persistent left superior vena cava drains into a dilated coronary sinus and can cause left atrial outflow obstruction by impinging on the posterior wall of the left atrium. Residual obstruction can persist, even after surgical resection of the cor triatriatum membrane. We describe a novel surgical treatment in a patient with cor triatriatum and persistent left superior vena cava.

• Article: Left atrial myxoma in a child with unique presentation: chest pain.

  ABSTRACT: We present a 16-year-old girl who presented with chest pain. Given her obesity and positive family history, she was felt to have atherosclerotic heart disease. However, an echocardiogram showed an atrial myxoma, which prompted surgical excision. This case supports the routine use of echocardiography and widened differential diagnosis when presented with pediatric chest pain.

  ABSTRACT: Reports on outcomes of acute type A aortic dissection (ATAAD) repair after previous cardiac surgery (PCS) are few. Some suggest no difference in mortality while others note decreased risk of free rupture due to adhesions. We analyzed our experience of ATAAD after PCS. Between January 1992 and March 2009 we repaired 330 patients with ATAAD. Of these, 49 (15%) patients had PCS: coronary artery bypass in 30 (61%), aortic valve replacement in 8 (16%), coronary artery bypass/aortic valve replacement in 5 (10%), aortic valve replacement-mitral repair in 1 (2%), aortic valve replacement-tricuspid repair in 1 (2%), and others in 4 (9%) patients. The ATAAD patients with and without PCS (primary) were compared. The PCS group was older (63 vs 58 years, p < 0.02), more frequently men (82% vs 67%, p < 0.04), and less likely to have aortic insufficiency (30% vs 47%, p < 0.05). Otherwise, the PCS group did not differ in clinical presentation, with similar malperfusion and tamponade. Operative procedures did not differ between groups except for repair of pulmonary artery fistula (4% vs 0%, p < 0.03), more use of Cabrol shunt (18% vs 3%), p < 0.03), and more frequent need for mechanical cardiac support in the PCS group (8% vs 3.6%, p < 0.04). The PCS group suffered more strokes (10% vs 2.5%, p < 0.03), temporary neurologic deficits (24% vs 10%, p < 0.007), and higher hospital mortality (31% vs 13.8%, p < 0.007) than the no-PCS group. Patients with ATAAD after PCS exhibited similar risks for malperfusion, hypotension, and cardiac tamponade. This suggests that adhesions formed after PCS do not eliminate the risk of cardiac tamponade from aortic rupture. Although results from surgical repair are acceptable, justifying timely repair, mortality still remains higher than without prior history of cardiac surgery.
