About

This study aims to achieve the following objectives

• objective 1 : To review the Investigators' experience of surgical management of infective endocarditis (IE) and analyze the outcomes and associated prognostic factors
• objective 2 : To provides information on early and late clinical outcomes of patients undergoing surgery for IE
• objective 3 : To evaluate the impact of perioperative clinical variables and identification of perioperative prognostic factors
• objective 4 : To determine the indications of surgical intervention and the best time of the surgery

Full description

The role of surgery in active infective endocarditis (IE) has been expanding since the first report of successful ventricular septal repair and removal of tricuspid vegetation in 1961 and the first successful valve replacement during active IE in 1965 "4".

The risk of death and complications of infective endocarditis (IE) treated medically has to be balanced against those from surgery in constructing a therapeutic approach .

The results of surgery depend upon many factors. The general preoperative condition of the patient, antibiotic treatment, timing of surgery, perioperative management, surgical techniques( including choice of methods for reconstruction), postoperative management, and follow-up are all important determinants of outcome .

Despite substantial improvements made in the diagnosis and management of infective endocarditis (IE), infective endocarditis remains a serious condition that is associated with significant morbidity and mortality. Compared with antibiotic treatment alone, surgery for IE has greatly increased survival "1".

Surgery for IE is required in 25-30% of cases during the acute phase and in 20-40% during the convalescent phase "2". The most common indications for surgery in IE include intractable heart failure, uncontrolled infection related to peri-valvular extension and resistant organisms, recurrent embolic events and presence of prosthetic material "3".

Risk stratification to identify patients at high risk of developing significant morbidity and mortality is important in the management of IE. Some authors have found operation during the acute phase of endocarditis to be associated with a higher risk of persistent or early recurrent prosthetic valve endocarditis (PVE)"5". Other studies did not find an increased recurrence rate "6", particularly not after surgery for mitral valve endocarditis "7". In general, the prognosis is better after early surgery undertaken before the cardiac pathology and the general condition of the patient have deteriorated too severely "8"
