Perfusion

In cases of severe cardiopulmonary deterioration, quick establishment of venoarterial extracorporeal membrane oxygenation (ECMO) represents a support modality. After successful arterial peripheral cannulation, a certain grade of peripheral limb malperfusion is a fairly common phenomenon. Detection of peripheral malperfusion is vital, since it can result in compartment syndrome or even loss of the affected limb. ⋯ Comparatively, the 17-Fr-sized cannula performs on a scale of 140 ± 20 to 390 ± 60 mL distal perfusion cannula blood flow at 1.5-5.0 L min-1 ECMO blood flow, respectively. The quantitative assessment of the distal perfusion cannula blood flow has revealed that distal perfusion cannula blood flow can measure up to 10% of the ECMO blood flow. Furthermore, it has been also well demonstrated that the novel distal perfusion cannula is sufficient to compensate peripheral limb ischaemia.

Clinical Trial
Early and long-term results of aortic valve sparing aortic root reimplantation surgery for bicuspid and tricuspid aortic valves.
To evaluate early and long-term clinical outcomes following aortic valve sparing aortic root reimplantation surgery in patients with leaking bicuspid and tricuspid aortic valves. ⋯ Aortic valve sparing aortic root reimplantation surgery is a safe and efficient technique, providing acceptable long-term survival with low rates of valve-related complications in both tricuspid aortic valve and bicuspid aortic valve patient groups. However, aortic valve reoperation rates at 10 years follow-up were higher in bicuspid aortic valve group patients compared to tricuspid aortic valve group patients.
