Team Situation Awareness (TSA) is one of the critical factors in effective Operating Room (OR) teamwork and can impact patient safety and quality of care. While previous research showed a relationship between situation awareness, as measured by communication events, and team performance, the implications for developing technology to augment and facilitate(More)
In aortic valve sparing surgery, cusp prolapse is a common cause of residual aortic insufficiency. To correct cusp pathology, native leaflets of the valve frequently require adjustment which can be performed using a variety of described correction techniques, such as central or commissural plication, or resuspension of the leaflet free margin. The practical(More)
BACKGROUND Data comparing outcomes after repair versus replacement of chronic ischemic mitral regurgitation (MR) is evolving. Recent data suggest that repair is associated with recurrent MR, but not survival, when compared with replacement. However, it remains unclear when either surgical strategy should be applied based on preoperative mitral valve(More)
OBJECTIVE The minimally invasive coronary artery bypass grafting (MICS CABG) operation performed via a small thoracotomy has not previously been examined in a direct comparison to sternotomy off-pump coronary artery bypass grafting (OPCAB). METHODS We matched, according to age, gender, left ventricular function, and median number of distal anastomoses,(More)
OBJECTIVE Minimally invasive coronary artery bypass grafting is safe and widely applicable, and may be associated with fewer transfusions and infections, and better recovery than standard coronary artery bypass grafting. However, graft patency rates remain unknown. The Minimally Invasive Coronary Artery Bypass Grafting Patency Study prospectively evaluated(More)
BACKGROUND As aortic valve (AV) repairs become more sophisticated, surgeons need increasingly detailed information about the structure and function of this valve. Unlike two-dimensional transesophageal echocardiography (2D-TEE), using three-dimensional (3D)-TEE makes it possible to image the entire AV. We hypothesized that measuring coaptation surface area(More)
Minimally invasive coronary artery bypass grafting (MICS CABG) is a nonrobotic, nonthoracoscopic operation that achieves complete anatomical graft similarity with conventional CABG, while avoiding sternotomy and cardiac anoxia. We describe the stepwise approach to perform proximal anastomoses directly off the ascending aorta and also early results of this(More)
We present the case of a healthy, asymptomatic 50-year-old woman with a systolic ejection murmur who was found to have an obstructive left ventricular outflow tract mass. Transthoracic echocardiography revealed a large mobile mass attached to the basal anterior septum of the left ventricle. Surgical resection was performed and a benign left ventricular(More)
OBJECTIVE We examined the effects of learning curve on clinical outcomes and operative time in minimally invasive coronary artery bypass grafting (MICS CABG). METHODS We studied 210 consecutive MICS CABG cases performed by the same surgeon, composed of 3 cardiopulmonary bypass (CPB)-assisted single-vessel small thoracotomy (SVST), 87 off-pump SVST, 51(More)
In the past decades, developments in transesophageal echocardiography (TEE) have opened new horizons in reconstructive surgery of the aortic valve (AV), whereby corrections are made to normalize the geometry and function of the valve, and effectively treat leaks. To the best of our knowledge, we propose the first integrated framework to process(More)
