“…Theoretically, this might be related to the low oxygen content of the venous blood, the low pressure in the right heart and to the differences in the endothelial covering and the vascularization of the right heart, thus the higher prevalence is among the population of congenital heart diseases with predominant left to right shunts 2). In our patient, alcoholism and probably diabetes were the major predisposing risk factors due to their proven negative impact on the immune system at multiple cellular levels 6). The patient denied any history of intra-venous drug abuse.…”

Pulmonic valve infective endocarditis in isolation is a rare clinical entity. The formation of an abscess in the right ventricular outflow tract as a consequence of vegetations affecting the pulmonic valve in a structurally normal heart is extremely rare and has not been reported. We report a case of isolated pulmonic valve endocarditis complicated by a regional abscess formed within the right ventricular outflow tract caused by Streptococcus Constellatus (S. Constellatus), a member of the Streptococcus Milleri group in a young male whose risk factor was alcohol abuse and he was treated medically, a comprehensive literature review on the subject is also reported. Our case is the first reported in literature with infective endocarditis caused by S. Constellatus affecting the pulmonic valve, and the first with pulmonic valve endocarditis and perivalvular abscess formation in a structurally normal heart.

“…Also, thorough echocardiographic evaluation of all cardiac valves, including right-sided valves, should be carried out in all patients with suspecting infective endocarditis, especially when the patient has a risk factor [4]. Due to the low sensitivity of TTE for evaluating the pulmonary valve (vegetations are only identified by TTE in 70% of the cases), TOE is the next step in the diagnostic workup after blood cultures being positive [2]. …”

We present a case of a fifty-three-year-old male who presented with severe sepsis. He had been treated as a pneumonia patient for five months before the admission. Investigations revealed isolated pulmonary valve endocarditis and septic pulmonary embolism in addition to undiagnosed right ventricular outflow tract (RVOT) obstruction. The patient underwent surgery for the relief of RVOT obstruction by substantial muscle resection of the RVOT, pulmonary artery embolectomy, pulmonary valve replacement, and reconstruction of RVOT and main pulmonary artery with two separate bovine pericardial patches. He was discharged from our hospital after 6 weeks of intravenous antibiotics. He recovered well on follow-up 16 weeks after discharge. A high-suspicion index is needed to diagnose right-side heart endocarditis. Blood cultures and transesophageal echocardiogram are the key diagnostic tools.

“…The most common infectious agents causing pulmonary endocarditis are Staphylococci [1,7,8,9,10]. Streptococci is less common [1,11,12]. Seldom the lesion can be due to Enterococci [13,14] or Candida spp.…”

Surgical Treatment of Infective Endocarditis in Pulmonary Position—15 Years Single Centre Experience

et al. 2019

Background and Objectives: Infective endocarditis in the pulmonary position is a rare disease. Isolated pulmonary valve endocarditis is extremely rare. The aim of our study was to assess patients who were treated surgically for pulmonary endocarditis at our institution from January 2003 to December 2017. Materials and Methods: We analyze eight cases of infectious endocarditis in pulmonary position out of 293 patients who were operated for infective endocarditis (2.7%, 8/293). Only two of these eight patients were not related to congenital heart malformation. They were followed for early and late mortality, long-term survival, postoperative morbidity and reoperations. Results: Among six patients suffering from congenital heart disease, four patients underwent corrections of pulmonary valve malformation previously, and their infected grafts were replaced by two allografts and two xenografts. The two other patients had replaced their infected pulmonary valves with allografts. Two non-congenital patients with pulmonary valve endocarditis underwent valve replacement with biological prosthesis. All patients survived the early postoperative course. The mean follow-up time was 9.1 (interquartile range (IQR), 5.3–12.6) years. The long-term follow-up included seven patients. One patient (12.5%, 1/8) died more than 4 years after the surgery due to sepsis. Pulmonary endocarditis was the rarest endocarditis treated surgically (p < 0.001). Conclusion: Surgery for infective endocarditis in the pulmonary position (IEPP) is an effective method of treatment with excellent early outcome and good late results despite a very uncommon pathology and few operations being performed. Surgery performed earlier may make the procedure less radical.
