Objectives: Patients with impaired renal functions have a variable risk of morbidity and mortality in cardiovascular surgery. Poor outcome was reported among patients who underwent valve surgery. Current study is presumed to compare the early outcomes of patients having different degrees of impaired renal functions and undergoing mitral valve replacement surgery. Methods: 135 patients were admitted into the three highly specialized centers in Cairo and Ismailia–Egypt between Dec.2018 and Jan.2020 Preoperative, intraoperative and early post-operative data were recorded. Impairment may present as one of these strata: early reversible (G1-2 included strata 1 & 2 kidney disease patients), moderate G3-4 included strata 3 & 4 kidney disease patients) or advanced irreversible renal damage. (The 5th stratum or G5-KD included end stage renal disease patients undergoing 4-hour hemodialysis sessions, three times a week, with bicarbonate dialysate). We correlated outcome among each stratum with cardiac and renal functions in that stratum. Results: The more is the impairment of renal functions at any peri- operative stage, the longer is the need for prolonged mechanical ventilation and the longer is the hospital stay. We found that levels of serum creatinine were significantly increased postoperatively Also, the more is the reversibility of the renal impairment, even by renal dialysis, the much better is the outcome (P=.0019). We also found insignificant difference between different strata of irreversible renal impairment in the early outcome of the prosthetic mitral valve replacement surgery. The early reversible damage can be repaired peri-operatively. Conclusions: Prosthetic mitral valve replacement among patients with different degrees of impaired renal functions is not only feasible but also it does not seem to add any more deterioration into renal function. Prolonged mechanical ventilation and hospital stay are the only drawbacks of irreversibly impaired renal damage by dialysis or renal transplant.

Objective:Right ventricular dysfunction constitutes a major risk factor for patients suffering from degenerative mitral valve disease. The objective of this study was to assess right ventricular function by echocardiography and to detect role of right ventricular functions in prediction of outcome following mitral valve replacement operation in patients with rheumatic heart disease involving mitral valve. Methods:Transthoracic 3D echocardiography was done in 52 patients posted for mitral valve replacement surgery. Right ventricular function was analyzed by measuring fractional area change (FAC) of right ventricle, tethering distance and, tricuspid annular plane systolic excursion (TAPSE). Tricuspid regurgitation was graded 0 to 4. Based on echocardiographic ndings of right ventricle, patients were allocated in two groups; Group A (normal right ventricular function) and Group B (poor right ventricular function). After surgery, incidence of complications such as; low cardiac output syndrome, refractory arrhythmia and, sepsis were compared in two group. Results: Incidence of postoperative complication such as low cardiac output syndrome and sepsis was signicantly more in patients with poor right ventricular function. Right ventricular variables, FAC <35%, TAPSE <17 mm and tethering distance > 8 mm are independent predictors of postoperative complications. Tricuspid valve was repaired in patients with grade 3 and 4 regurgitation. Therefore cardiopulmonary bypass time was signicantly more in patients with grade 3 and 4 TR (84.42±69.77 min) (p<0.01). Duration of intensive care support was also signicantly more in patients with poor right ventricular function (p<0.001) Conclusion: To predict possible complications and outcome following mitral valve replacement surgery, right ventricular functions should be thoroughly assessed by 3D echocardiography

Objective: To determine the role of perioperative milrinone on pulmonary hypertension in patients with mitral valve disease undergoing mitral valve replacement surgery. Study Design: Randomized Control Trial. Setting: Department of Cardiac Surgery, Faisalabad Institute of Cardiology, Faisalabad. Period: June 2019 to June 2020. Material & Methods: A total of 80 patients with mitral valve disease who underwent mitral valve replacement were included. The patients were divided into a control group of 40, who were not administered milrinone, and a study group of 40 who received milrinone perioperatively. TVPG, LVEF and NYHA class were recorded preoperatively and postoperatively and were compared. Results: In the study group, postoperative LVEFs and NYHA class were not statistically significant in both groups while postoperative TVPG was significantly lower in study group as compare to control group and is statistically significant (P<0.001). Conclusion: Our study concludes that milrinone can be used as an effective therapy to reduce pulmonary pressure in patients with pulmonary hypertension undergoing mitral valve replacement surgery.

Objectives: The objective of this study was to see whether there is an association between high blood glucose levels after operation under CPB and post operative morbidity and mortality. Methodology: This cohort study was carried out in the Department of Cardiac Surgery at National Institute of Cardiovascular DiseaseS (NICVD), Sher-e-Bangla Nagar, Dhaka from January, 2012 to December, 2013 for a period of twenty four (24) months. A total number of 110 patients who underwent MVR operation with CPB were enrolled in this study as per inclusion and exclusion criteria. Patients were divided into two groups according to their post operative blood glucose levels, recorded with in first 60 hrs after mitral valve replacement surgery under cardiopulmonay bypass. Patients having blood glucose level of less than 10.1 mmol/L (unexposed) and patients having blood lactate level of 10.1 mmol/L or more (exposed) were grouped. Post operative variables were observed and recorded during the hospital course of the patient. Result: A total number of 110 patients were enrolled in this study. Blood glucose levels lower than or equal to10 mmol/L after MVR were present in 55(50%) patients (Group A) Blood glucose levels higher than 10 mmol/L after MVR were present in 55(50%) patients. Postoperative morbidity was higher in this group ( Group B) than in the patients who had peak blood glucose levels of less than or equal to 10 mmol/L MVR (p 0.001). Postoperative ICU stay was prolonged in patients with elevated levels of blood glucose after MVR under CPB compared with of patients with lower blood glucose levels (p 0.001). Other common morbidities are neurological complication (p 0.04), renal dysfunction (p 0.01) , wound infection (p 0.04), post-operative hospital stay ( p0.004). also higher in group B patient, as well as mortality. Conclusions: Blood glucose concentration of 10.1 mmol/ L or higher after MVR under CPB is an important issues related to postoperative morbidity and mortality.
