can be treated less invasively with transcatheter aortic valve implantation (TAVI). Different access routes have been proposed for TAVI, including transapical, transsubclavian, and transfemoral, with percutaneous transfemoral being preferred because it is the least invasive and nonsurgical. Bernard Chevalier, MD, Institut Cardiovasculaire Paris Sud, Massy\/Quincy, France, presented data from the Massy TAVI database regarding the institute\u0027s early and later experience with performing 170 transfemoral TAVIs (140 patients with full percutaneous approach).\u003C\/p\u003E\n      \u003Cp id=\u0022p-3\u0022\u003EPatients in the early and later experience groups had similar demographics, patients in the later group were at higher risk, based on Euro scores (26.9 \u00b1 11.8 vs 21.1 \u00b1 10.7 in the late group; p=0.003) and left ventricular ejection fraction (LVEF; 45.8 \u00b1 13.1 vs 54.3 \u00b1 14.2 in the late group; p\u0026lt;0.001). Access vessel diameter was measured angiographically or with multislice computed tomography (MSCT). Patients were required to have calcification and tortuosity scores between 0 and 3. Vascular complications (20 patients vs 8 in the late group; p=0.012) occurred significantly more often among patients in the early group, most likely due to a learning curve with the Prostar device. This translated into longer intensive care unit stays (7.5 vs 3.3 days; p=0.039) in the earlier cohort, despite their lower risk profile.\u003C\/p\u003E\n      \u003Cp id=\u0022p-4\u0022\u003EThe optimum sheath:femoral artery ratio (SFAR) was 1.05 mm. Ratios that were higher than this were associated with significantly (p\u0026lt;0.05) more frequent femoral artery, iliac artery, and Valve Academic Research Council (VARC) major and minor vascular complications, as well as mortality (both in-hospital and 30-day). Factors that were predictive of major VARC complications were body mass index, early experience, SFAR, and femoral artery minimum luminal diameter.\u003C\/p\u003E\n      \u003Cp\u003EProf. Chevalier presented his top tips to reduce vascular access complications during TAVI:\n\u003C\/p\u003E\n      \u003Cul class=\u0022list-unord \u0022 id=\u0022list-1\u0022\u003E\u003Cli id=\u0022list-item-1\u0022\u003E\n            \u003Cp id=\u0022p-6\u0022\u003EDo not use an 18F sheath if common femoral arter (CFA) \u0026lt;6.8 mm\u003C\/p\u003E\n         \u003C\/li\u003E\u003Cli id=\u0022list-item-2\u0022\u003E\n            \u003Cp id=\u0022p-7\u0022\u003EStick the middle of the anterior wall of the CFA\u003C\/p\u003E\n         \u003C\/li\u003E\u003Cli id=\u0022list-item-3\u0022\u003E\n            \u003Cp id=\u0022p-8\u0022\u003EUse fluoroscopy to check the deployment of the 4 needles\u003C\/p\u003E\n         \u003C\/li\u003E\u003Cli id=\u0022list-item-4\u0022\u003E\n            \u003Cp id=\u0022p-9\u0022\u003EIntroduce large sheath only on extra stiff wire\u003C\/p\u003E\n         \u003C\/li\u003E\u003Cli id=\u0022list-item-5\u0022\u003E\n            \u003Cp id=\u0022p-10\u0022\u003EProgress with a back-and-forth rotation\u003C\/p\u003E\n         \u003C\/li\u003E\u003Cli id=\u0022list-item-6\u0022\u003E\n            \u003Cp id=\u0022p-11\u0022\u003EEliminate large iliac dissections before removing the sheath\u003C\/p\u003E\n         \u003C\/li\u003E\u003Cli id=\u0022list-item-7\u0022\u003E\n            \u003Cp id=\u0022p-12\u0022\u003EMake the surgical knots with wet sutures at the end of the TAVI\u003C\/p\u003E\n         \u003C\/li\u003E\u003Cli id=\u0022list-item-8\u0022\u003E\n            \u003Cp id=\u0022p-13\u0022\u003EKeep the wire in place when pushing the first knot\u003C\/p\u003E\n         \u003C\/li\u003E\u003Cli id=\u0022list-item-9\u0022\u003E\n            \u003Cp id=\u0022p-14\u0022\u003ECheck angiographically from the opposite side after closure\u003C\/p\u003E\n         \u003C\/li\u003E\u003C\/ul\u003E\n      \u003Cp\u003E\n         \u003C\/p\u003E\n      \u003Cp\u003EIn order to deal with potential complications, it is important to be comfortable with specific techniques, including a crossover, balloon angioplasty, femoral stenting, and covered stenting.
