Therapeutic application of inhaled nitric oxide in adult cardiac surgical patients.

Increased pulmonary vascular resistance can be detrimental to the cardiac output in post-operative cardiac surgical patients. Pulmonary vasodilator therapy by systemic pharmacologic agents is non-selective. Inhaled nitric oxide is a selective pulmonary vasodilator and does not cause systemic hypotension.

Predictors of operative mortality following primary coronary artery bypass surgery.

Background: Although quality assessment of coronary artery patients can be done by 30 days risk-adjusted operative mortality, it is still insufficient to study the outcome after primary coronary artery bypass graft surgery (CABG). In our study, we attempted to determine the factors, which can help predict operative mortality before and after CABG.

Methods: The study population consisted of 1000 prospective patients who underwent primary isolated CABG.

Coronary artery bypass grafts assessment at one year by noninvasive multislice computed tomography and invasive coronary angiography.

Objective: : The aim of this study was to evaluate and compare the postoperative graft patency by multislice computed tomography (MSCT) and invasive coronary angiography (ICA) in patients with multivessel coronary artery bypass grafting at 1 year of surgery.

Methods: : Patients (n = 114) who underwent isolated coronary artery bypass grafting at least 1 year (1.4 ± 0.

Three-Dimensional Reconstruction of Ultrafast 16-Slice Computed Tomography Images and CT Angiography Versus Conventional Coronary Angiography at One Year in Multivessel Coronary Artery Bypass Surgery.

Background: : The aim of this study was to evaluate and compare the postoperative graft patency assessment by multislice spiral computed tomography (MSCT) scan and conventional coronary angiography (CCA) in coronary artery bypass grafting (CABG) patients 1 year after surgery.

Methods: : Sixty-nine patients who underwent isolated CABG at least 1 year before the study, were subjected to both MSCT angiography with cardiac gating and CCA. The results were evaluated and compared.

A prospective evaluation of hemodynamic instability during off-pump coronary artery bypass surgery.

Objective: Despite recognized hemodynamic derangements during cardiac displacement, most patients appear to tolerate the off-pump procedure well. However, some patients unpredictably become hemodynamically unstable requiring emergency cardiopulmonary bypass or intra-aortic balloon pump support. After an experience of 5306 multivessel off-pump coronary artery bypasses (OPCABs), this study was undertaken to determine the factors that would identify the patients who were at a higher risk for the procedure.
