Importance The safety and effectiveness of mitral valve repair via thoracoscopically-guided minithoracotomy (minithoracotomy) compared with median sternotomy (sternotomy) in patients degenerative regurgitation is uncertain. Objective To compare the vs a randomized trial. Design, Setting, Participants A pragmatic, multicenter, superiority, clinical trial 10 tertiary care institutions UK. were adults undergoing surgery. Interventions 1:1 concealed allocation to receive either or performed by...
Right ventricular (RV) long-axis function is known to be depressed after cardiac surgery, but the mechanism not known. We hypothesized that intraoperative transesophageal echocardiography could pinpoint time at which this happens help narrow range of plausible mechanisms. Transthoracic was conducted in 33 patients before and elective coronary artery bypass graft. In an intensively monitored cohort 9 patients, we also RV intraoperatively using serial pulsed wave tissue Doppler (PW TD)...
Aortic stenosis causes angina despite unobstructed arteries. Measurement of conventional coronary hemodynamic parameters in patients undergoing valvular surgery has failed to explain these symptoms. With the advent percutaneous aortic valve replacement (PAVR) and developments pulse wave analysis, it is now possible instantaneously abolish measure resulting changes waves that direct flow.Intracoronary pressure flow velocity were measured immediately before after PAVR 11 with Using we...
Fingerprint Presentation Attack Detection (FPAD) deals with distinguishing images coming from artificial replicas of the fingerprint characteristic, made up materials like silicone, gelatine or latex, and alive fingerprints. Images are captured by modern scanners, typically relying on solid-state optical technologies. Since 2009, Liveness Competition (LivDet) aims to assess performance state-of-the-art algorithms according a rigorous experimental protocol and, at same time, simple overview...
The International Fingerprint liveness Detection Competition (LivDet) is an open and well-acknowledged meeting point of academies private companies that deal with the problem distinguishing images coming from reproductions fingerprints made artificial materials relative to real fingerprints. In this edition LivDet we invited competitors propose integrated algorithms matching systems. goal was investigate at which extent integration impact on whole performance. Twelve were submitted...
Coronary artery bypass graft (CABG) surgery may induce myocardial stunning and thereby affect cardiac function. We aimed to assess whether function is affected by CABG in patients with preserved preoperative systolic function.Myocardial tissue peak velocities were recorded at the lateral septal angle of mitral annulus as well tricuspid pulsed wave Doppler echocardiography before surgery, then 5 days, 6 weeks 18 months after surgery.Thirty-two consecutive left ventricular (31 male, 63+/-10...
Patients undergoing coronary artery bypass grafting (CABG) experience a reduction in right ventricular long axis velocities post surgery.We tested whether the phenomenon of (RV) velocity decline depends on chest being opened fully by mid-line sternotomy, pericardial incision, or type operation performed.By intraoperative transoesophageal echocardiography (TEE) we recorded serial systolic pulse-wave tissue Doppler during 6 types elective procedure: 53 CABG surgery, 15 robotic-assisted...
Objective Minimally invasive aortic valve replacement (MIAVR) has been demonstrated as a safe and effective option but remains underused. We aimed to evaluate outcomes of isolated MIAVR compared with conventional (CAVR). Methods Data from The National Institute for Cardiovascular Outcomes Research (NICOR) were analyzed at seven volunteer centers (2006–2012). Primary in-hospital mortality midterm survival. Secondary postoperative length stay well cumulative bypass cross-clamp times....
The International Fingerprint Liveness Detection Competition is an international biennial competition open to academia and industry with the aim assess report advances in Presentation Attack Detection. proposed "Liveness Action" "Fingerprint representation" challenges were aimed evaluate impact of a PAD embedded into verification system, effectiveness compactness feature sets for mobile applications. Furthermore, we experimented new spoof fabrication method that has particularly affected...
