Alan Wilson and Szeto Zajarias show that vascular complications of the trans-femoral path remain an important factor because of the high profile of the catheters used in TAVI and the appearance of smaller devices, as well as the experience of surgeons, will progressively reduce complication rates. Josep Rodes-Cabau commented about the negative impact a stroke...
The pressure ratio in the resting phase of the cardiac cycle is a newly Introduced procedure for the assessment of coronary stenoses based on pressure measurement without adenosine. It generated interest with over 1500 comparisons with the FFR since its introduction at TCT 2011. The discrepancies between the two methods have been attributed to the...
ISAR-DESIRE 3 did not show that paclitaxel-eluting balloon may be useful for treating restenosis of a sirolimus–eluting stent. This study tests the safety and efficacy of a paclitaxel-eluting balloon versus a paclitaxel-eluting stent in cases of in-stent drug-eluting restenosis. We included 220 patients with in-stent restenosis of a drug-eluting stent ball randomized at a 1:1...
The simple strategy with a provisional stent is now favored to treat bifurcation lesions; however, stent implantation in the main branch can compromise or even occlude the side branch. Pre-dilation of the side branch could lower the chances of this happening. We included 372 patients with bifurcation lesions (Medina 111, 011 and 101); the technique...
The objective of the study was to test the use of a new atherectomy device to prepare severely calcified lesions. It was an observational, prospective, multicenter study that included 443 patients from 49 sites with a 30-day follow-up. The lesion was classified as severely calcified, as fluoroscopy showed the presence of calcium on both sides...
There is little information about the use of bioresorbable vascular devices in patients with a reference diameter ≥4mm, long, bifurcation, calcified or unstable lesions. The BVS-Expand registry is a single-center study that evaluates the safety and efficacy of this device in past populations (real world).The primary endpoint was the occurrence of MACE (cardiac death, myocardial...
Percutaneous aortic valve replacement (TAVI) is a new treatment option for patients that are inoperable or present a high surgical risk. Some studies have shown that the stroke rate may be higher with TAVI than with medical treatment or surgical replacement. Embolic protection has been used successfully for the carotids, but there is not much...
The objective of the study was to assess events after 30 days with the DirectFLOW Medical Valve device in patients with severe aortic stenosis and high surgical risk. The device is designed to reduce post-implant aortic regurgitation; it has a low profile and high navigability and requires no post-dilatation or rapid pacing. The study included...
The study aims to evaluate clinical, angiographic and IVUS results of the new platinum chromium everolimus stent. The new design of the device has additional proximal connectors to enhance the longitudinal strength where distortion is more common. Included were 100 patients with de novo coronary lesions and a reference diameter of 2.5 to 4 mm...
This non-inferiority design study compared the sirolimus-eluting stent with biodegradable polymer versus everolimus-eluting stent with permanent polymer in de novo coronary lesions. The primary endpoint was late lumen loss at nine months. We Included 440 patients with stable coronary lesions randomized 2:1 to receive the new sirolimus eluting stent with biodegradable polymer versus everolimus eluting...
