Abstract

BACKGROUND: While prosthetic rings are commonly used for mitral valve repairs, autologous pericardium is an alternative ring material that can be used in these procedures. In this report, we aim to present a comparison of two types of rings used for mitral repair. METHODS: Between January 2005 and January 2009, 107 patients who underwent mitral valve repair surgery were analyzed. Patients were divided into two groups, according to the type of ring that was used for mitral annular stabilization. Glutaraldehyde-treated pericardial rings were used for 31 patients (group 1), whereas prosthetic rings were used for 76 patients (group 2). Survival, freedom from reoperation, recurrent mitral regurgitation, and the effects of rheumatic mitral disease on these parameters were evaluated and compared for both groups. RESULTS: Follow-up time for our cohort was 4.24±0.4 years. There were four and seven late mortalities in groups 1 and 2, respectively, and five reoperations in each group. There was no significant difference between the groups, in terms of survival, freedom from reoperation, and recurrent mitral regurgitation (log-rank analyses for both groups were P = 0.777, P = 0.346, and P = 0.781, respectively). There was no significant difference in freedom from reoperation and recurrent mitral regurgitation for both groups, in terms of underlying rheumatic valvular disease and other types of pathology. CONCLUSION: Pericardial ring annuloplasty shows to be a considerable alternative technique for mitral valve repair procedures in the mid- to long-term follow up. Rheumatic mitral valves had poor outcomes, when compared with other types of structural valvular pathologies in cases where pericardial rings were used in the repair procedure., NA

Abstract

OBJECTIVES To conduct a survey across European cardiac centres to evaluate the methods used for cerebral protection during aortic surgery involving the aortic arch. METHODS All European centres were contacted and surgeons were requested to fill out a short, comprehensive questionnaire on an internet-based platform. One-third of more than 400 contacted centres completed the survey correctly. RESULTS The most preferred site for arterial cannulation is the subclavian-axillary, both in acute and chronic presentation. The femoral artery is still frequently used in the acute condition, while the ascending aorta is a frequent second choice in the case of chronic presentation. Bilateral antegrade brain perfusion is chosen by the majority of centres (2/3 of cases), while retrograde perfusion or circulatory arrest is very seldom used and almost exclusively in acute clinical presentation. The same pumping system of the cardio pulmonary bypass is most of the time used for selective cerebral perfusion, and the perfusate temperature is usually maintained between 22 and 26°C. One-third of the centres use lower temperatures. Perfusate flow and pressure are fairly consistent among centres in the range of 10-15 ml/kg and 60 mmHg, respectively. In 60% of cases, barbiturates are added for cerebral protection, while visceral perfusion still receives little attention. Regarding cerebral monitoring, there is a general tendency to use near-infrared spectroscopy associated with bilateral radial pressure measurement. CONCLUSIONS These data represent a snapshot of the strategies used for cerebral protection during major aortic surgery in current practice, and may serve as a reference for standardization and refinement of different approaches
