OBJECTIVE Previous studies comparing off-pump coronary artery bypass surgery (OPCABG) to conventional techniques utilizing cardiopulmonary bypass (CABG-CPB) have failed to provide patient selection guidelines. We sought to determine guidelines, attempting to rectify the limitations of previous studies. METHODS AND RESULTS A retrospective analysis of prospectively collected data from the Socie...

Cardiogenic shock or pump failure may be defined as severe circulatory failure resulting from a primary defect in the pumping function of the heart, most commonly from acute myocardial infarction, and less commonly from end-stage congestive cardiomyopathy. It is essential that surgically correctable lesions leading to pump failure are identified and these would include papillary muscle dysfunct...

Surgical treatment of heart failure is emerging as one of the most challenging clinical dilemmas for patients with end-stage cardiac failure not amenable to medical treatment. One of the most intriguing techniques is the use of implantable left ventricular assist devices (LVADs) as a bridge to recovery. The early experience from our centre has shown that even short term post-cardiotomy mechanic...

OBJECTIVE Acute right ventricular (RV) failure is a life-threatening condition with a poor prognosis, and sometimes the use of mechanical circulatory support is inevitable. In this article, we describe our experience using a centrifugal pump as a temporary percutaneous right ventricular assist device (RVAD) in patients with postoperative acute refractory RV failure after left ventricular assist...

OBJECTIVES The aim of this study was to determine the significance of peripheral monocytosis in clinical outcome after reperfused acute myocardial infarction (AMI), especially relating to post-infarct left ventricular (LV) remodeling. BACKGROUND Peripheral monocytosis occurs two to three days after AMI, reflecting infiltration of monocytes and macrophages into the necrotic myocardium. However...

Laser-based metrology has been identified as an enabling technology in the deployment of large, space-borne observatories, where nanometer-level knowledge of fiducial displacement drives overall system performance. In particular, Nd:YAG NPRO (non-planar ring oscillator) based lasers have received considerable attention in this application because of their inherent high coherence at wavelengths ...

INTRODUCTION The use of coronary artery bypass surgery (CABG) with cardiopulmonary bypass (CPB) or without CPB technique (off-pump) can be associated with different mortality and morbidity and their outcomes remain uncertain. The goal of this study was to evaluate the early outcome of on-pump versus off-pump CABG. METHODS We conducted a retrospective database review of 13866 patients (13560 p...
