Registration of a 4D Cardiac Motion Model to Endoscopic Video for Augmented Reality Image Guidance of Robotic Coronary Artery Bypass
"... Abstract. The aim of the work described in this paper is registration of a 4D preoperative motion model of the heart to the video view of the patient through the intraoperative endoscope, in order to overlay the real video sequence with it. As the heart motion is cyclical it can be modelled using mu ..."

multiple reconstructions of cardiac gated coronary CT. We propose the use of photoconsistency between the two views through the da Vinci endoscope to align to the preoperative heart surface model from CT. We propose averaging of the photoconsistency over the cardiac cycle to improve the registration
Towards Endoscopic Augmented Reality for Robotically Assisted Minimally Invasive Cardiac Surgery
, 2001
"... One of the problems tightly linked to endoscopic surgery is the fact that, because of the narrow field of view, it is sometimes quite difficult to locate the objects that can be seen through the endoscope. This is especially true in cardiac surgery, where it is difficult to not confuse two coronary ..."

The combined association of depression and socioeconomic status with length of post-operative hospital stay following coronary artery bypass graft surgery: Data from a prospective cohort study ☆
, 2014
"... Objective: To understand the association between pre-operative depression symptoms, including cognitive and somatic symptom subtypes, and length of post-operative stay in patients undergoing coronary artery bypass graft (CABG) surgery, and the role of socioeconomic status (SES). Methods: We measure ..."

110Case Report Minimally Invasive Surgery for Coronary Artery Disease with Associated Lung Cancer
"... Simultaneous surgical management of patients with co-existing ischemic heart disease and lung carcinoma remains controversial. Traditionally, these operations have been staged, with coronary artery revascularization first, followed by pulmonary resection at a later date. Under this procedure, tumor ..."

ABSTRACT Counterpulsation in dogs with normal systemic arterial blood pressure produced a reduction in myocardial oxygen consumption without a significant concomitant change in total coronary flow. In dogs with a deteriorating heart and low systemic arterial blood pressure, myocardial oxygen consum ..."

Counterpulsation reduced the mean systemic arterial blood pressure during ventricular ejection to a greater

Beneficial Effects of o^-Adrenoceptor Activity on Ischemic Myocardium During Coronary Hypoperfusion in Dogs
