Table 1 Porcine pressure measurements of the aortic root and ascending aorta
From: The functional limits of the aneurysmal aortic root. A unique pressure testing apparatus
Porcine specimen aortic root | Maximal pressure (mmHg) | Macroscopic characteristics | Porcine specimen ascending aorta only | Maximal pressure (mmHg) | Macroscopic characteristics |
|---|---|---|---|---|---|
1 | 180 | • Tissue dissection at site of pressure transducer • Circumferential spread of dissection | 1 | 300+ | • No loss of tissue integrity • Apparatus failure |
2 | 200 | • Tissue dissection at site of pressure transducer • Luminal tear at coronary ostia • Circumferential spread of dissection | 2 | 300+ | • No loss of tissue integrity • Apparatus failure |
3 | 220 | • Tissue dissection at site of pressure transducer • Luminal tear at coronary ostia • Circumferential spread of dissection | 3 | 300+ | • No loss of tissue integrity • Apparatus failure |
4 | 200 | • Tissue dissection at site of pressure transducer • Circumferential spread of dissection | 4 | 300+ | • No loss of tissue integrity • Apparatus failure |
5 | 240 | • Tissue dissection at site of pressure transducer • Circumferential spread of dissection | 5 | 300+ | • No loss of tissue integrity • Apparatus failure |
