Acute Aortic Regurgitation Secondary to Aortic Dissection

Diretrizes para a cirurgia das doenças da aorta

“…Não obstante os excelentes resultados cirúrgicos de alguns grupos, que relatam uma mortalidade hospitalar entre 6 e 12% 3,4,6,7,16,[25][26][27][28] , o International Registry of Acute Aortic Dissection 29 , em levantamento retrospectivo de 464 casos de dissecções agudas da aorta atendidos em 12 centros de referência nos EUA, entre 1996 e 1998, aponta uma mortalidade operatória de 26% na dissecção aguda tipo A, valor possivelmente mais aproximado da média em nossa realidade.…”

Aortic Insufficiency Secondary to Aortic Root Aneurysm or Dissection

“…This permitted resection of aneurysmal sinuses of Valsalva and extension of the graft to the valve anulus, except in the region of the left coronary orifice. 1 There have been three deaths in this group. One patient devel¬ oped a sternal wound infection, which led to massive bleeding, presumably from a disrupted aortic suture line.…”

Surgical treatment of aneurysms of the ascending aorta associated with severe aortic regurgitation.

“…In most cases valve dysfunction is due to loss of commissural support. Hence many favour resuspension of the aortic leaflets.4 6 17 [20][21][22] There are, howAntunes, Baptista, Colsen, Kinsley ever, several reports of late failure and subsequent valve replacement.523 We routinely replace the valve where there is more than moderate regurgitation.…”

“…With these techniques the mean duration of cardiopulmonary bypass was 98 (SD 26) minutes and the aorta was cross clamped for 68 (20) minutes. In one patient circulatory arrest at 22°C was used for 29 minutes.…”
