Late complication of the Nuss procedure: recurrent cardiac tamponade: Won Jong Park, Jang Won Son, Kyu Hwan Park, You Min Kim, Jong Ho Nam, Kang Un Choi, Jung Ho Kim; Yeungnam Univ J Med. 2019;36(3):260-264. Published online June 13, 2019; DOI: https://doi.org/10.12701/yujm.2019.00241

Abstract PDF: Pectus excavatum (PE) is known as one of the most common congenital deformities of the anterior chest wall. The Nuss procedure is an effective surgical therapy to correct PE. Here, we report a case of recurrent cardiac tamponade due to hemopericardium that occurred after 16 months following the Nuss procedure. The cause of recurrent hemopericardium was thought to be local, repetitive irritation of the pericardium by the Nuss steel bar. We should keep in mind that this serious complication can occur after the Nuss procedure, even in the late phase.

Severe chest pain with mid-ventricular obstruction in a patient with hyperthyroidism: Jong Ho Nam, Jang Won Son, Geu Ru Hong; Yeungnam Univ J Med. 2017;34(1):128-131. Published online June 30, 2017; DOI: https://doi.org/10.12701/yujm.2017.34.1.128

Abstract PDF: Mid-ventricular obstruction (MVO) rarely occurs in patients without hypertrophic cardiomyopathy. Increased cardiac contractility may play an important role in causing MVO. We experienced a case of severe chest pain and MVO in a 50-year-old female patient. She had hypertension, diabetes, stroke and peripheral artery disease. Her blood pressure was very high (222/122 mmHg) with severe fluctuation. The transthoracic echocardiography revealed MVO accompanied by hyper-dynamic left ventricular systolic function. We regarded her chest pain and MVO as secondary findings related to other diseases. Coronary angiography and several tests for uncontrolled hypertension were performed, and those evaluations revealed that she had coronary artery disease and hyperthyroidism. We considered that the increase in the myocardial oxygen demand in response to the increase in cardiac contractility and workload associated with hyperthyroidism aggravated her symptoms and MVO. She was treated with methimazole and beta blockers and her symptoms dramatically improved.

Bronchogenic cyst masquerading as malignant pericardial effusion with tamponade: Kang Un Choi, Byung Jun Kim, Hong Ju Kim, Jang Won Son, Jong Seon Park, Dong Gu Shin, Young Jo Kim; Yeungnam Univ J Med. 2017;34(1):91-95. Published online June 30, 2017; DOI: https://doi.org/10.12701/yujm.2017.34.1.91

Abstract PDF: We report on a rare case involving a 23-year-old female patient with mediastinal cystic mass complicated with acute pericarditis and cardiac tamponade. Pericardial fluid demonstrated lymphocyte-predominant exudate and the level of carcinoembryonic antigen (CEA) was unexpectedly elevated. Successive aspiration of mediastinal cystic mass revealed a very high level of CEA (>100,000 U/mL) and carbohydrate antigen 19-9 (>15,000 ng/mL). This patient was clinically diagnosed as an infected bronchogenic cyst complicated with pericarditis and cardiac tamponade. The treatment resulted in alleviation of her symptoms.

Unusual paradoxical embolic stroke in a patient with persistent left superior vena cava.: Tae Hun Kwon, Kang Un Choi, Byung Jun Kim, Jae Ho Cho, Jae Young Lee, Kyu Hwan Park, Sang Hee Lee, Jang Won Son; Yeungnam Univ J Med. 2015;32(2):118-121. Published online December 31, 2015; DOI: https://doi.org/10.12701/yujm.2015.32.2.118

Abstract PDF: Cardiogenic embolic stroke accounts for approximately 20% of ischemic strokes and the likelihood of its recurrence is high. Paradoxical embolism may be an important cause of cardioembolic stroke, which can be evaluated through multiple diagnostic modalities including transesophageal echocardiography (TTE) or transcranial Doppler. A persistent left superior vena cava (PLSVC) is a rare congenital vascular anomaly, which mainly drains to the right atrium via the coronary sinus. Although rare, PLSVC draining into the left heart predisposes the patient to paradoxical embolism through a right-to-left shunt. We report on a 78-year-old female patient with an ischemic stroke associated with PLSVC draining into the left atrium through the pulmonary vein, which was investigated via TTE with an agitated saline test and computed tomography.

Early Stage Loeffler's Endocarditis Detected by Transthoracic Echocardiography.: Min Kyu Kang, Won Jong Park, Sung Yun Jung, Su Mi Kim, Tae Hun Kwon, Young Ha Ryu, Jang Won Son, Dong Gu Shin; Yeungnam Univ J Med. 2012;29(2):118-120. Published online December 31, 2012; DOI: https://doi.org/10.12701/yujm.2012.29.2.118

Abstract PDF: Loeffler's endocarditis involves progressive eosinophilic infiltration of the endocardium, which leads to apical thrombotic obliteration of the ventricle and endomyocardial fibrosis, that may finally represent a characteristic feature of restrictive cardiomyopathy. This paper presents a case of a 44-year-old male with symptoms of dyspnea and peripheral hypereosinophilia, who was diagnosed with early stage Loeffler's endocarditis via multicardiac imaging modalities.
