Comparative Study
Effects of inhaled nitric oxide following lung transplantation.
Lung transplantation offers an established therapeutic option for end-stage lung disease. It is associated with several complications, and early allograft failure is one of the most devastating among all. Different studies are focused on an attempt to minimize these complications, especially transplant failure. We aimed to evaluate the effects of inhaled nitric oxide (iNO) treatment in patients receiving lung transplantation. ⋯ Nitric oxide inhalation for the prevention and treatment of early allograft failure in lung transplant recipients is encouraging. It is superior to other vasodilators with its selectivity to the pulmonary vasculature, while having no significant side effects on systemic circulation. It appears to improve gas exchange and oxygenation properties. Further prospective randomized studies will aid to standardize inhalation nitric oxide therapy.

The impact of intraaortic balloon counterpulsation on bypass graft flow in patients with peripheral ECMO.
Numerous reports have been performed to investigate the hemodynamic effects of intraaortic balloon pumping (IABP) and nonpulsatile circulatory extracorporeal membrane oxygenation (ECMO), but studies on its impact on coronary artery bypass graft flow during concomitant use of IABP and ECMO are lacking. The aim of this study was to assess the impact of additional IABP support on the degree of blood flow increase in bypass grafts in high-risk patients with nonpulsatile femoral venoarterial ECMO. ⋯ We conclude that IABP-induced pulsatility significantly improves coronary bypass graft flows during nonpulsatile peripheral ECMO.

Results of treatment methods in cardiac arrest following coronary artery bypass grafting.
Emergency re-revascularization and invasive/noninvasive interventions in intensive care unit (ICU) are two main treatment methods in cardiac arrest following coronary artery bypass grafting (CABG). We evaluated the short- and long-term consequences of these two methods and discussed the indications for re-revascularization. ⋯ Better short- and long-term results were observed in the re-revascularization group.

Predictive models for the length of stay (LOS) in the intensive care unit (ICU) following cardiac surgery have been developed in the last decade. These risk models use different endpoint and risk factor definitions. This review discusses the need for a uniform multi-institutional risk scoring system for a prolonged ICU LOS. ⋯ There is a need for the development of a multi-institutional risk scoring system for prolonged ICU LOS following cardiac surgery. This predictive model could aid in quality assessment, practice improvement, patient counseling, and decision making. In order to develop this risk model, uniformed and standardized definitions are needed.

We treated a 61-year-old woman with mitral stenosis caused by pannus formation after Duran ring annuloplasty. Pannus overgrowth on the ring with extension onto both leaflets narrowed the mitral orifice and severely restricted the mobility of the valve leaflets. ⋯ Jude Medical mechanical heart valve prosthesis was successfully performed, and the postoperative course was uneventful. Patients undergoing Duran ring annuloplasty should be followed up with the consideration of possible mitral stenosis caused by pannus extension, as the cause for pannus formation remains unclear.
