승모판 폐쇄 부전증에 의한 심부전의 경우 대부분 양측폐에 대칭적으로 폐부종이 발생하지만 일부의 경우 국소적인 폐부종 형태로 나타날 수 있으며 대부분 우상엽에 발생하며 우중엽에 동반되기도 한다. 승모판 폐쇄 부전증 환자의 흉부 방사선 소견상 일측성 침윤이 보일때 폐렴과 국소적인 폐부종을 감별해야 할 것이다.
An 82-year-old female non-smoker with a history of hypertension presented with increasing dyspnea, cough and some purulent sputum without fever. Upon admission, the patient was in a distressed condition. Auscultation revealed diminished breath sounds with no rales over the right lung. An examination of the heart revealed a regular rhythm and a systolic murmur radiating from the apex of the heart. There was no pitting edema in the lower extremities. The blood tests showed mild leukocytosis and an increased C-reactive protein level. The $O_2$ saturation was 98 % whilst breathing room air. The electrocardiogram demonstrated sinus tachycardia. The chest radiograph showed a moderate cardiomegaly, right lobe infiltrates, and blunting of the both costophrenic sulcus suggesting a small pleural effusion. Three days after admission, the symptoms became slightly aggravated despite being treated with empirical antibiotics for presumed community-acquired pneumonia. Transthoracic color Doppler echocardiography indicated an ejection fraction of 48 %, mild left ventricular enlargement, and moderate left atrial enlargement resulting in severe mitral regurgitation. The clinical symptoms and right pulmonary edema resolved quickly with intravenous furosemide treatment.
