A Pilot Study Comparing Aortic Valve Area Estimates Derived from Fick Cardiac Output with Estimates Based on Cheetah-NICOM Cardiac Output.

Cardiac output during cardiac catheterization is often estimated using the modified Fick method (CO). In this proof-of-concept, prospective non-randomized study carried out in a single academic healthcare centre, we examined whether replacing CO in the Gorlin formula with Cheetah-NICOM monitor cardiac output (CO) could produce an accurate and precise estimate of aortic valve area in patients with severe aortic stenosis. In twenty-six subjects, CO and CO were obtained concurrently.

When we should say no to TAVR-Defining the line between utility and futility.

History of prior coronary artery bypass surgery (CABG) is a frequent scenario encountered in patients with severe symptomatic aortic stenosis deemed inoperable and referred for transcatheter aortic valve replacement (TAVR). Aside from indices of frailty and other comorbidities, these patients remain at higher risk for peri-operative mortality and morbidity compared to their counterparts without prior CABG. Presence of concomitant peripheral arterial disease and patent left internal mammary artery (LIMA) graft pose further access related challenges.

Impella left ventricular assist device in cardiac arrest after spinal anaesthesia for caesarean section.

Cardiac arrest after neuraxial anaesthesia is very well described. Inhibition of the sympathetic efferent system and vagal activation leading to decrease preload and severe bradycardia results in cardiac arrest. Pregnant patients undergoing spinal anaesthesia are at increased risk for vasovagal events due to aortocaval compression and higher level of spinal block.

Emergency department inter-hospital transfer for post-cardiac arrest care: initial experience with implementation of a regional cardiac resuscitation center in the United States.

Objective: The American Heart Association recently recommended regional cardiac resuscitation centers (CRCs) for post-resuscitation care following out-of-hospital cardiac arrest (OHCA). Our objective was to describe initial experience with CRC implementation.

Methods: Prospective observational study of consecutive post-resuscitation patients transferred from community Emergency Departments (EDs) to a CRC over 9 months.

A randomized comparison of a novel bioabsorbable vascular closure device versus manual compression in the achievement of hemostasis after percutaneous femoral procedures: the ECLIPSE (Ensure's Vascular Closure Device Speeds Hemostasis Trial).

Objectives: This trial compared the performance of a novel bioabsorbable vascular closure device (VCD) versus manual compression (MC) for access site hemostasis in patients undergoing percutaneous trans-femoral coronary or peripheral procedures.

Background: From a patient's perspective, access site management after percutaneous procedures remains challenging.

Methods: Patients enrolled in this multicenter, nonblinded trial underwent 6-F diagnostic or interventional procedures were randomly assigned 2:1 to VCD versus MC.
