Clinical characteristics and safety of valvular surgery in elderly patients aged over 75 years / 中华胸心血管外科杂志

ABSTRACT

Objective:To study the clinical characteristics and surgical conditions of valve surgery in elderly patients over 75 years old.Methods:Datas of patients over 75 years old with valve surgery in our hospital from January 2014 to January 2019 were retrospectively analyzed. 73 cases were analyzed, accounting for 5.3%(73/1 372) of the cardiac valve operations performed during the same period.There were 46 males and 27 females, with an average age of 77.35 years(75-88 years). The main diagnoses were MR 28 cases(38.3%), MS 8 cases(11.0%), AR 7 cases(9.6%), AS+ AR 7 cases(9.6%) and AS 6 cases (8.2%). There were 28 cases(38.4%) of MVR+ TVP, 20 cases(27.4%) of AVR, and 11 cases(15.1%) of MVR.Pacemakers were installed in 2 patients(2.7%) and coronary artery bypass grafting was performed in 14 patients(19.2%).Results:There were statistically significant differences in left atrial end-diastolic diameter(LA), left ventricular end-diastolic diameter(LV), right atrial end-diastolic diameter(RA) and ejection fraction(EF) before and after surgery( P<0.05). There were no statistically significant differences between the two groups( P>0.05) in surgical interception time, extracorporeal circulation time, postoperative ventilator time, ICU time, surgical complications, postoperative liver and kidney functioninsufficiencyand mortality, as compared with 150 cases of valve surgery under 60 years old( P>0.05). Conclusion:Mitral regurgitation is the most common valvular disease in senile patients over 75 years old, the cardiac structure is improved significantly after surgery, and the risk of surgery is the same as that in normal age groups. Therefore, valvular surgery issafe in elderly patients over 75 years old.
