Trends in Heart Valve Surgery in Korea: A Report from the Heart Valve Surgery Registry Database.

Background: In this study, we present recent trends in heart valve surgery in Korea through analyses of data from the Korea Heart Valve Surgery Registry (KHVSR).

Methods: We enrolled 8,981 patients who were registered in the KHVSR from 2017 to 2020. Yearly trends in patients' baseline characteristics, surgical profiles, and early mortality rates were explored.

Impact of chronic kidney disease on clinical outcomes in patients with Stage B progressive aortic regurgitation (mild to moderate and moderate grades).

Background: Chronic kidney disease (CKD) is a significant comorbidity in patients with heart failure and valvular heart disease. Renal impairment is not well evaluated in the patients with Stage B progressive aortic regurgitation (AR) (mild to moderate and moderate grades in this study), for estimating outcome.

Hypothesis: We sought to investigate the prognostic factor, especially CKD, in the patients with progressive AR.

Idiopathic hypereosinophilic syndrome with intracardiac atypical linear-shaped and floating thrombus presenting as embolic cerebral infarction.

Knowledge of the multi-organ involvement in hypereosinophilic syndrome (HES) is important for the diagnosis and care of patients with this condition, even in cases with atypical presentation. This report aims to describe cerebral embolic infarction and intracardiac atypical linear-shaped thrombus in a patient with idiopathic HES and to discuss the approach of appropriate diagnosis and timely interventional management. A 55-year-old man presented with general weakness, including left-sided weakness, mild cognitive dysfunction, and mild exertional dyspnea for about 2 weeks.

Temporary use of unusually high dose of catecholamine improved severe ventricular dysfunction associated with stunned myocardium without significant myocardial injury in a post cardiac surgical patient: A case report.

Introduction: Some cardiac surgical patients present low cardiac output syndrome due to ventricular dysfunction resulting from postischemic myocardial stunning. We present a case of using unusually high dose of inotropes so that we could avoid mechanical circulatory support after cardiac surgery.

Presentation Of Case: A 65-year-old man underwent elective cardiac surgery.

Cardiac impalement injury by a steel rebar: A case report.

Introduction: Penetrating cardiac injury often occurs in South Korea. However, impalement injury of the heart with other organs is rare and fatal. We present a case of cardiac impalement injury by a steel rebar.

Multi-Modality Imaging of Coronary Artery Fistula with Giant Aneurysms.

A 50-year-old woman was referred to our hospital with a chief complaint of chest pain. Coronary angiography revealed a fistula between the left anterior descending artery and pulmonary artery with giant aneurysms. Although coronary angiography is considered the standard tool to confirm a coronary artery fistula, the patient in this case underwent successful surgical repair with the aid of multi-modality imaging.

Isolated metastasis of hepatocellular carcinoma in the right ventricle: A case report.

Metastatic hepatocellular carcinoma (HCC) of the right ventricle is very rare and difficult to diagnosis.A 79-year-old man who underwent right hemi-hepatectomy for HCC was admitted to our hospital for chest pain, severe dyspnea, and orthopnea. The echocardiogram showed a tumor located in the right ventricle.

Prediction of Intimal Tear Site by Computed Tomography in Acute Aortic Dissection Type A.

Background And Objectives: Preoperative identification of intimal tear site in acute type A dissection will help procedural planning. The objective of this study was to determine the key findings of computed tomography (CT)-based prediction for tear site and compare the accuracy between radiologists and surgeons.

Subjects And Methods: Multi-detector CT (MDCT) images from 50 patients who underwent surgical repair of type A aortic dissection were retrospectively reviewed by 4 cardiac surgeons with limited experience or by 3 radiologists specialized in cardiovascular imaging.

Change of Proximal Descending Aortic False Lumen after Conventional Repair of Acute Type I Dissection: Is It Always Unfavorable?

Background: Some patients show favorable changes in the descending aortic false lumen after conventional repair of acute type A dissection, although the incidence of favorable changes has been reported to be low. We aimed to investigate the incidence of positive postoperative changes in the false lumen and the factors associated with positive outcomes.

Methods: In 63 patients who underwent surgery for type A acute dissection as well as serial computed tomography (CT) scanning, morphological parameters were compared between the preoperative, early postoperative (mean interval, 5.

Sternal healing after coronary artery bypass grafting using bilateral internal thoracic arteries: assessment by computed tomography scan.

Background: This study aimed to investigate sternal healing over time and the incidence of poor sternal healing in patients undergoing coronary artery bypass graft (CABG) surgery using bilateral internal thoracic arteries.

Methods: This study enrolled 197 patients who underwent isolated CABG using skeletonized bilateral internal thoracic arteries (sBITA) from 2006 through 2009. Postoperative computed tomography (CT) angiography was performed on all patients at monthly intervals for three to six months after surgery.

Clinical results of cardiovascular surgery in the patients older than 75 years.

Background: The balance of the risks and the benefits of cardiac surgery in the elderly remains a major concern. We evaluated the early and mid-term clinical results of patients aged over 75 years who underwent major cardiovascular surgery.

Methods: Two hundred and fifty-one consecutive patients, who underwent cardiac surgery at Seoul National University Bundang Hospital between July 2003 and June 2011, were included in this study (mean age, 78.

Accuracy of CT angiography in the assessment of the circle of Willis: comparison of volume-rendered images and digital subtraction angiography.

Background: Computed tomography angiography (CTA) is increasingly used for non-invasive imaging of the cerebrovascular diseases.

Purpose: To evaluate the accuracy of CTA in the assessment of the variation of the segment calibers of the circle of Willis.

Material And Methods: One hundred and 17 patients with acute SAH (51 men and 66 women, mean age 50.

Small atypical cervical nodes detected on sonography in patients with squamous cell carcinoma of the head and neck: probability of metastasis.

Objective: The purpose of this study was to assess the probability of metastasis of small atypical cervical lymph nodes detected on sonography in patients with squamous cell carcinoma (SCC) of the head and neck.

Methods: We reviewed, retrospectively and blindly, sonographic findings of 148 patients (118 men and 30 women; mean age, 58.2 years) who underwent curative neck dissection.

Cyclosporin A has a protective effect with induced upregulation of Hsp70 and nNOS on severe spinal cord ischemic injury in rabbits.

The purpose of this study is to ascertain the neuroprotective effect of cyclosporin A on the 25-min surgical ischemia model in the spinal cords of rabbits with neuropathological correlation and histoimmunochemical analyses measuring HSP70 and neuronal NOS (nNOS). New Zealand white rabbits were randomly divided into four groups (each n = 8): the C2, C7, Cs2, and Cs7 groups. The C2 and C7 groups underwent a 25-min surgical aortic cross-clamp without intervention and were sacrificed respectively on day 2 and on day 7 postoperatively.

Pulmonary endometriosis resected by video-assisted thoracoscopic surgery.

Catamenial haemoptysis is a rare condition caused by thoracic endometriosis that presents as tracheobronchial or pulmonary endometriosis. The authors report a 31-year-old woman with a 1-year history of catamenial haemoptysis, which was diagnosed by chest CT scan during menses and treated successfully by means of video-assisted thoracoscopic surgery of the solitary pulmonary lesion. There was no evidence of recurrence 6 months after the operation.
