“…The most prevalent type of surgery is CABG, in this study performed in 54 patients, confirming the published literature, followed by valve replacement [6,18,27,28]. The valve repair has become the procedure of choice for treatment of mitral valve disease.…”

Objective: To present the complications that prolong the stay in the Intensive Care Unit (ICU) of the patients undergoing cardiac surgery.Methods: We retrospectively analyzed records of 85 patients undergoing cardiac surgery during the period of March to May 2009, at the Santa Casa de Misericordia de Juiz de Fora (MG), and, of these patients we studied 14 (16.47%) who stayed for more than five days in ICU. Amongst the 85 patients, there were three deaths, being two patients operated on an emergency basis, which increases morbidity, and one patient who remained in the hospital and under mechanical ventilation (MV) for 21 days.Results: The study showed that complications that increased the length of stay in ICU were respiratory and metabolic disorders, according to the literature. Conclusion:The complications that increase length of stay in ICU are related to respiratory function, chronic obstructive pulmonary disease, smoking, lung congestion, prolonged switch-off from MV, diabetes, infections, kidney failure, stroke and hemodynamic instability. 167LAIZO, A ET AL -Complications that increase the time of Hospitalization at ICU of patients submitted to cardiac surgery Bras Cir Cardiovasc 2010; 25(2): 166-171 Rev

“…This is because there is no ideal substitute to provide a long life, without the use of oral anticoagulants, with no increased risk of thromboembolism and operating mechanism similar to the native valve [8][9][10][11][12][13][14]. Still, the clinical decision becomes increasingly challenging with the increase in life expectancy and the presence of comorbidities such as advanced age, congestive heart failure, coronary artery disease, pulmonary disease and renal failure [6].…”

Resultados de pacientes submetidos à cirurgia de substituição valvar aórtica usando próteses mecânicas ou biológicasOutcomes of patients subjected to aortic valve replacement surgery using mechanical or biological prosthesesThis study was carried out at Clinics Hospital of Porto Alegre, Porto Alegre, RS, Brazil. AbstractObjective: This paper evaluates outcomes in patients subjected to surgery for replacement of the aortic valve using biological or mechanical substitutes, where selection of the type of prosthesis is relevant.Methods: Three hundred and one patients, randomly selected, who had been subjected to aortic valve replacement surgery between 1990 and 2005, with a maximum follow-up period of 20 years.Results: Survival at 5, 10 and 15 years after surgery using mechanical substitute was 83.9%, 75.4% and 60.2% and, for biological substitute, was 89.3%, 70.4% and 58.4%, respectively (P=0.939). Factors associated with death were: age, obesity, pulmonary disease, arrhythmia, bleeding and aortic valve failure. Probability free of reoperation for these patients at 5, 10 and 15 years after surgery using mechanical substitute was 97.9%, 95.8% and 95.8% and, for those using bioprostheses, was 94.6%, 91.0% and 83.3%, respectively (P=0.057). Factors associated with reoperation were: renal failure, prosthesis endocarditis and age. Probability free of bleeding events at 5, 10 and 15 years after surgery using mechanical substitute was 94.5%, 91.7% and 91.7% and, for bioprostheses, was 98.6%, 97.8% and 97.8%, respectively (P=0.047). Factors associated with bleeding events were: renal failure and mechanical prostheses.Conclusions: The authors have concluded that: 1) mortality was statistically similar in the groups; 2) patient characteristics at baseline were a major determinant of late mortality after surgery; 3) there was a tendency toward reoperation in the bioprostheses group; 4) patients using mechanical prosthesis had more bleeding events as time passed; 5) data presented in this paper is in accordance with current literature.

“…The degenerative calcification of the aortic valve is considered the most common cause of aortic stenosis in developed countries, the most frequent indication for aortic valve replacement [1][2][3][4][5]. Standard treatment involves replacing of the valve by a prosthetic device (biological or mechanical) with operative mortality around 4% [6.7].…”
