Cardiac Performance after Open Intracardiac Surgery.
THE hemodynamic state, blood gas levels, blood volumes, and residual shunts soon after repair of atrial septal defect, ventrieular septal defect, and tetralogy of Fallot have been described in previous publications.1-4 Similar data have now been obtained after open operation for acquired disease of the aortic valve, and additional measurements of atrial pressures after repair of ventricular sep...
متن کاملMassive intracardiac thromboembolism following spinal surgery.
microRNA plasma levels correlate with troponin and cardiac function in patients with ST elevation myocardial infarction, are selectively dependent on renal elimination, and can be detected in urine samples.

متن کاملA novel cardioport for beating-heart, image-guided intracardiac surgery.
OBJECTIVE Intracardiac beating-heart procedures require the introduction and exchange of complex instruments and devices. To prevent potential complications such as air embolism and bleeding, a universal cardioport was designed and tested. METHODS The design consists of a port body and a series of interchangeable sleeves. The port uses a fluid purging system to remove air from the instrument ...
متن کاملRobotic Motion Compensation for Beating Heart Intracardiac Surgery
3D ultrasound imaging has enabled minimally invasive, beating heart intracardiac procedures. However, rapid heart motion poses a serious challenge to the surgeon that is compounded by significant time delays and noise in 3D ultrasound. This paper investigates the concept of using a one-degree-of-freedom motion compensation system to synchronize with tissue motions that may be approximated by 1D...
متن کاملRobotic Force Stabilization for Beating Heart Intracardiac Surgery
The manipulation of fast moving, delicate tissues in beating heart procedures presents a considerable challenge to surgeons. We present a new robotic force stabilization system that assists surgeons by maintaining a constant contact force with the beating heart. The system incorporates a novel, miniature uniaxial force sensor that is mounted to surgical instrumentation to measure contact forces...
