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.

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.

Recurrent acinic cell carcinoma in the parotid gland with cardiac metastasis and hypertrophic osteoarthropathy.: Sung Yun Jung, Dong Won Lee, Min Geun Gu, Tae Hun Kwon, Sung Ae Ko, Joon Hyuk Choi, Jang Won Sohn, Myung Soo Hyun; Yeungnam Univ J Med. 2014;31(1):33-37.

Abstract PDF: Acinic cell carcinoma (ACC) is an uncommon malignant tumor of the salivary glands that is difficult to diagnose. It grows slowly and shows distant metastasis rarely. We experienced a case of recurrent ACC in the parotid gland with cardiac metastasis and hypertrophic osteoarthropathy. The 29-year-old man had been suffering from severe multiple bones and joints pain for 2 months. Ten years earlier, he underwent superficial parotidectomy due to a right subauricular mass. The mass was diagnosed with ACC. After surgery, the tumor recurred twice. Then the patient was diagnosed with cardiac metastasis via positron emission tomography-computed tomography and trans-thoracic echocardiography. He also had hypertrophic osteoarthropathy with multiple bone metastasis. He was given palliative radiotherapy and conservative treatment. ACC in the parotid gland with cardiac metastasis and hypertrophic osteoarthropathy has not yet been reported in literature. From this case, it is recommended to evaluate multiple distant metastasis in the ACC of the parotid gland when joint and bone pain are present.

Died immediately after corrective surgery for right ventricular acute myocardial infarction and ventricular septal rupture.: Su Mi Kim, Sung Yun Jung, Min Jung Kim, Tae Hun Kwon, Kang Un Choi, Byung Jun Kim, Jang Won Sohn, Gue Ru Hong; Yeungnam Univ J Med. 2014;31(1):9-12. Published online June 30, 2014; DOI: https://doi.org/10.12701/yujm.2014.31.1.9

Abstract PDF: Postinfarction ventricular septal rupture (VSR) is a rare but fatal complication of acute myocardial infarction. In many cases, postinfarction VSR leads to hemodynamic instability and urgent surgical treatment is necessary. Here we describe a case of a patient with right ventricular (RV) dysfunction caused by acute RV infarction and with cardiogenic shock, whose condition improved after development of postinfarction VSR, but the patient died after corrective surgery.

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.
