Abstract:
Pneumococcal endocarditis is a rare entity, corresponding to 1 to 3% of native valve endocarditis cases. It has a typically adverse prognosis, with high mortality. There is a reported predilection for the aortic valve; thus, a common presentation is acute left heart failure. We present a case of a 60-year-old woman with a history of sinusitis, who was admitted with the diagnosis of pneumonia. She rapidly deteriorated with signs of septic shock and was transferred to the critical care unit. The transesophageal echocardiogram revealed severe aortic regurgitation due to valve vegetations. Blood cultures were positive for Streptococcus pneumoniae. She underwent cardiac surgery and had multiple postoperative complications. Nonetheless, the patient made a slow and complete recovery. Infectious endocarditis should be ruled out if any suspicion arises, and echocardiography should be performed in an early stage in patients with poor response to vasopressors and inotropes. Patients with pneumococcal endocarditis benefit from an aggressive approach, with performance of early surgery.
Insights
Pneumococcal endocarditis, a rare heart valve infection, often presents with severe aortic regurgitation. Early surgical intervention and aggressive treatment are crucial for patient recovery and improved outcomes in these critical cases.
