Infective endocarditis remains an important, life-threatening infection despite improvements in diagnosis and management. Despite the decrease in rheumatic heart disease and the improvements in antibiotic prophylaxis, infective endocarditis has been reported with increasing frequency in the last few decades. Presumably, this is due to the rise in the incidence of intravenous drug users, carriers of prosthetic valves and other intracardiac devices, and the longer survival of patients with congenital heart disease. Despite the great advances in medical and surgical treatment, infective endocarditis is still a life-threatening disease with an estimated mortality of 27%. Infective endocarditis represents one of the few potentially fatal infections that may occur in a dental patient. Efforts to reduce the incidence of this disease usually take the form of appropriate antibiotic coverage before dental treatment, together with the establishment and maintenance of good oral health. This study is a case report of a patient who developed infective endocarditis after multiple tooth extractions due to chronic periodontitis of dental origin.

목적: 감염성 심내막염과 동반된 견관절 화농성 관절염의 치료 경험을 보고하고자 한다. 대상 및 방법: 감염성 심내막염에 동반한 화농성 견관절염을 가진 70세 남자 환자에 대하여 심장 판막 치환술 및 관절경하 활막 절제술과 배농술을 시행 하였다. 결과: 감염에 대한 순조로운 치유와 기능의 회복을 보였다. 결론: 상대적으로 견관절에 화농성 관절염이 동반되는 경우는 매우 드문 것으로 보고 되고 있으나 감염성 심내막염에 동반하는 일반적인 근골격계 증상으로 간과한다면 심각한 합병증으로 발생할 수 있음으로 주의 깊게 판단하여야 한다고 생각한다.

Bacteremia occurs in a wide variety of clinical procedures in oral cavity. Reduction of the number of causative microorganisms of infective endocarditis in oral cavity by local administration of antimicrobial agents decreases the magnitude of bacteremia and possibility of infective endocarditis. The effects of chlorhexidine on Streptococcus sanguis, Streptococcus mitis, Streptococcus mutans, Streptococcus oralis, Streptococcus gordonii, Staphylococcus aureus, and Staphylococcus epidermis were investigated by measurement of turbidity. The effects of 0.1% chlorhexidine gargling for 7 days on oral bacterial flora, total streptococci, S. mutans, S. aureus, and S. epidermis in whole saliv a of 7 healthy human subjects, were investigated by measurement of Colony Forming Units (CFU). The obtained results were as follows : 1. Chlorhexidine showed significant antimicrobial effects on Streptococcus snaguis, Streptococcus mitis, Streptococcus mutans, Streptococcus oralis, Streptococcus gordonii, Staphylococcus aureus, and Staphylococcus epidermis. However, the effects on S. sanguis and S. gordonii were not apparent compared with other microorganisms. 2. Oral gargling of 0.1% chlorhexidine decreased the CFU values of normal oral bacterial flora, total streptococci, S. mutans, S. aureus, and S. epidermis in whole saliva. The antimicrobial effects were significant after 4 days of chlorhexidine gargling. 3. Local antimicrobial administration in addition to systemic antibiotic prophylaxis can be highly recommended as an effective adjunct regimen for prevention of infective endocarditis.

We report a case of perivalvular abscess in a 66-year-old man with infective endocarditis, diagnosed by late gadolinium-enhanced (LGE) cardiovascular magnetic resonance (CMR) imaging. No clinical features suspicious of infective endocarditis were noted, however, transthoracic echocardiography revealed non-specific echogenic focal wall thickening at mitral-aortic intervalvular fibrosa. Perivalvular abscess in the aortic valve was demonstrated as focal wall thickening between the anterior mitral leaflet and the non-coronary cusp of the aortic valve with peripheral enhancement and central low signal intensity on LGE CMR imaging. Other features suggestive of infective endocarditis, such as neither vegetation nor valvular perforation were present. The perivalvular abscess did not grow after intensive intravenous antibiotics therapy, and the patient was discharged without surgical treatment. CMR with LGE provided an early accurate diagnosis of perivalvular abscess. The diagnosis of perivalvular abscess using LGE CMR imaging was not previously reported in Korea.

우측 심장에 발생한 감염성 심내막염은 전체 감염성 심내막염의 5%를 차지하며 이중 70%이상에서 선천성 심기형이나 후천성 판막질환 등에 동반되어 발생한다. 환자들은 약물 남용의 과거력을 갖는 경우가 많으며, 혈액투석 등 의인성 감염성 심내막염이 발생하는 경우도 있다. 우측 심장에 발생한 감염성 심내막염은 항생제 치료에 대한 반응이 우수하고, 내과적 치료에 반응하지 않더라도 판막손상이나 색전에 의한 합병증이 상대적으로 적게 발생하기 때문에 수술이 필요하지 않은 경우가 많다. 만성신부전으로 혈액투석을 받는 환자들은 관혈적 투석경로를 통해 균혈증에 노출되고 이로 인해 감염성 심내막염이 속발된다. 본 교실에서는 혈액투석을 받던 말기신부전 환자에서 정맥내 도관과 관련하여 삼첨판막이나 폐동맥판막의 침범없이 우심방내 우종을 동반한 심내막염이 발생하였으며, 항생제 치료를 시행하였으나 반응이 없어 수술을 시행하였다. 속목정맥도관과 관련된 우측 심장의 감염성 심내막염은 혈액투석환자에서 매우 드물게 발생하지만 진단이 지연되고 이로 인해 적절한 시기에 치료를 받지 못하여 병원내 사망률을 높이므로 적극적인 진단과 처치가 필요함을 확인할 수 있었기에 이를 문헌고찰과 함께 보고하는 바이다.

감염성 심내막염은 치과치료로부터 발생할 수 있는 심각한 심장질환 합병증이며, 생명을 위협하는 치명적인 상황을 초래할 수 있다. 따라서 심내막염 예방을 위하여 위험군에 속하는 환자에서 침습적 술식을 행하기에 앞서 예방적 항생제를 전투여한다. 본 증례는 영구치 근관치료 후 발생한 감염성 심내막염을 주소로 내원한 환아로서 심실중격결손으로 인해 예방적 항생제를 투여했음에도 불구하고 심내막염이 발병하여, 항생제 요법 후 의심되는 원인치아를 발거하고 심장수술을 시행하였다. 이에 다소의 지견을 얻었기에 보고하는 바이다.

We experienced a case of infective endocarditis of aortic valve and tricuspid valve associated with a fistula between aorta and right ventricle. The patient was 35 years old woman and showed severe congestive heart failure. Large and multiple vagetations were found on the valvular surfaces and a fistula was present between aorta and right ventricle. Probably infective endocarditis of aortic valve resulted in annular abscess and as it healed, a fistula was formed and tricuspid valve endocarditis followed. We replaced the aortic valve and tricuspid valve with St. Jude mechanical prostheses, and closed the fistula opening with suture. The postoperative course was smooth and the patient has no problems till now 4 months after operation.

Despite the multivariate improvements in tissue treatment, material, and design of prosthetic heart valves in recent years, numerous complications that may lead to valve dysfunction remain a constant threat after valve replacement. Most common indications for prosthetic valve failure are primary valve failure, infective endocarditis, paravalvular leakage, and thromboembolism. From 1977 to 1986, 15 patients underwent reoperation for prosthetic valve failure in 278 cases of valve surgery. The etiology of prosthetic valve failure were primary valve failure in 12 patients [80 %], infective endocarditis in 2 patients [13.3 %], and a paravalvular leakage [6.7 %]. The average durations of implantation were 45.5 months; 53.9 months in primary valve failure, 16 months in infective endocarditis, and 4 months in paravalvular leakage. The rate of valve failure was high under age of 30 [11/15]. Calcifications and collagen disruption of prosthesis were main cause of primary valve failure in macro- & micropathology. Prosthesis used in reoperation were 5 tissue valves and 10 mechanical valves. Operative mortality were 13.3 % [2/15], due to intractable endocarditis and ventricular arrhythmia.

From May 1984 through December 1991, twelve patients underwent valve replacement for infective endocarditis at National Medical Center. There were 7 male and 5 female, ranged in age 16 to 61[mean 34.1] years. Four had native valve endocarditis, six had prosthetic valve endocarditis and two were associated with congenital heart disease. The indication of surgery was medically intractable congestive heart failure in all patients. 5 patients revealed systemic embolization and 4 patients had uncontrollable sepsis. The causative organism was Streptococcus in 4 patients, Staphylococcus in 1 patient and Pseudomonas in 2 patients. Hospital mortality was 33.3%[4/12]. The main cause of death was low cardiac output due to perioperative myocardial damage and cerebral vascular accident. There were 2 late mortality because of recurrent endocarditis. This review showed much higher mortality in prosthetic valve endocarditis[66.7%] than native valve endocarditis[33.3%].

Coronary artery fistula is an abnormal communication between the coronary artery and the cardiac chambers. In particular, an abnormal connection between the conus branch of the right coronary artery and the proximal left anterior descending coronary artery is defined as Vieussens' arterial ring. Coronary artery fistulas are usually asymptomatic, but some can cause complications such as infective endocarditis. Here, we report a case of Vieussens' arterial ring causing infective endocarditis with severe mitral regurgitation.
