Bypass Ventrículo aórtico en estenosis aórticas críticas.

Treatment of aortic stenosis with aortic valve byp...[J Thorac Cardiovasc Surg. 2009] - PubMed Result: "CONCLUSIONS: An aortic valve bypass conduit as small as 10 mm results in excellent relief of left ventricular outflow tract obstruction in critical aortic valve stenosis. The presence of an aortic valve bypass conduit has no effect on cerebral blood flow. All blood flow to the brain occurs via antegrade flow across the native stenotic valve; this configuration may decrease the long-term risk of cerebral thromboembolism."

Cambio aórtico por toracotomía izquierda después de una cirugía de esófago.

Aortic valve replacement through left thoracotomy ...[Ann Thorac Surg. 2008] - PubMed Result:
Paciente con cirugía de esófago 14 años atrás, con tubo gástrico subesternal. Se abordó la válvula aórtica por toracotomía izquierda.
A 67-year-old man was referred for aortic valve surgery due to aortic valve regurgitation. He underwent an aortic valve replacement through a left thoracotomy, since he had a history of esophageal surgery with substernal gastric tube reconstruction and lymph node dissection through a right thoracotomy 14 years ago. The aortic valve was successfully replaced with excellent visualization using vacuum-assisted venous drainage on a cardiopulmonary bypass. Although exposing the aortic valve through a left thoracotomy is difficult, the application of vacuum-assisted venous drainage helps visualize the aortic valve in this approach."

Implante de válvula aórtica por cateter

Transcatheter valve implantation for patients with aortic stenosis...[Eur Heart J. 2008] - PubMed Result:
"CONCLUSION: Transcatheter aortic valve implantation is a promising technique, which may offer an alternative to conventional surgery for high-risk patients with aortic stenosis. Today, careful evaluation is needed to avoid the risk of uncontrolled diffusion."
