The purpose of this article is to provide a current review of the spectrum of multidetector CT (MDCT) and MRI findings for a variety of cardiac neoplasms. In the diagnosis of cardiac tumors, the use of MDCT and MRI can help differentiate benign from malignant masses. Especially, the use of MDCT is advantageous in providing anatomical information and MRI is useful for tissue characterization of cardiac masses. Knowledge of the characteristic MRI findings of benign cardiac tumors or thrombi can be

Background: Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) might be considered a bridge therapy in patients who are expected to have short waiting times for heart transplantation. We investigated the clinical outcomes of patients who underwent VA-ECMO as a bridge to heart transplantation and whether the deployment of an early extubation ECMO strategy is beneficial. Methods: Between November 2006 and December 2018, we studied 102 patients who received VA-ECMO as a bridge to heart tra

Long-segment tracheal stenosis in infants and small children is difficult to manage and can be life-threatening. A retrospective review of 12 patients who underwent surgery for congenital tracheal stenosis between 1996 and 2004 was conducted. The patients’ median age was 3.6 months. All patients had diffuse tracheal stenosis involving 40-61% (median, 50%) of the length of the trachea, which was suspected to be associated with complete tracheal ring. Five patients had proximal bronchial stenosis

Donor shortage is a major limitation in organ transplantation. Several studies have reported that extracorporeal membrane oxygenation (ECMO)-assisted organ donation can be successfully completed without inducing warm ischemia in patients with brain death. The present report described clinical experience of three patients (23-yr old man, 32-yr old man, and 41-yr old woman) who underwent ECMO for the evaluation of brain death and organ donation. They donated six kidneys, three livers, and one both

Purpose: Limited data are available on the role of percutaneous cardiopulmonary support (PCPS) for the treatment of acute myocardial infarction (AMI) patients with cardiogenic shock. We investigated the clinical outcomes and predictors of in-hospitalmortality after PCPS in patients with AMI complicated by severe refractory cardiogenicshock. Materials and Methods: From January 2004 to December 2011, we analyzed data from 96 consecutive AMI patients with cardiogenic shock assisted by a PCPS system

배경: 경피적 심폐 보조장치(PCPS)는 체내의 가스교환과 혈액의 관류를 간접적으로 도와줌으로써, 장기를 회복시키기 위한 다른 치료법의 사용을 용이하게 하고, 여러 다양한 임상 상황에서 출혈의 위험성을 최소화하면서 심각한 심폐부전에 빠진 환자의 생명을 구해준다. 본 저자들은 허혈성 심질환자들에서 발생한 심인성 쇼크 혹은 심정지를 PCPS로 치료한 경험을 보고하고자 한다. 대상 및 방법: 1999년 5월부터 2005년 6월까지 발생한 심정지 혹은 심인성 쇼크 환자들을 대상으로 연구가 진행되었고, 환자들 중 7명에서 원심펌프인 Biopump (Medtronic inc., Minneapolis, MN), 나머지 13명에게는 자가 priming이 되는 헤파린-코팅된 EBS (Terumo, Japan)를 사용하였다. 삽관은 모든 환자에서 대퇴 동맥과 대퇴 정맥을 통해서 이루어졌으며, 동맥용 케눌라는 17 Fr에서 21 Fr까지, 정맥용은 21 Fr에서 28 Fr까지의 DLP (Medtroni

Background and Objectives：Percutaneous cardiopulmonary support (PCPS) provides hemodynamic stabilityfor the treatment of patients suffering with cardiogenic shock or cardiac arrest, and it can be used in a wide varietyof clinical settings without the need for chest exploration. In this study, we summarize a single center’s experiencewith performing PCPS in the patients who suffered with severe cardiopulmonary failure. Subjects and Methods：We retrospectively reviewed 30 consecutive patients with

The purpose of this study was to investigate the operative results and the clinical outcomes for octogenarians who underwent cardiac surgery. Twenty consecutive octogenarians who had cardiac operations at Samsung Medical Center from October 1994 through December 2004 were included in the study. The medical records were retrospectively reviewed and the follow-up results were obtained by the interview. The patients were 15 men and 5 women, and their mean age was 83.1 yr (range: 80-89 yr). The surg

A new CT-based diagnostic method of protrusio acetabuli (PA) was introduced. However, prevalence of PA by this method and correlation between PA and other manifestations of Marfan syndrome (MFS) is unknown in Korean MFS patients. This study aimed to investigate the prevalence of PA diagnosed by a CT-based method in Korean patients with MFS, the association of PA with other manifestations of MFS, and the contribution of PA to MFS diagnosis. We retrospectively reviewed the records of 146 MFS patie

배경: 만성폐색전증으로 인한 폐동맥고혈압은 국내에 잘 알려져 있지 않으나 매우 나쁜 예후를 보이는 질환이다. 내과적인 치료는 그 효과가 적으며 고식적인 치료방법으로 사용된다. 폐동맥 내막절제술은 수술 술기 및 술 후 관리의 발달에 따라 이 질환의 가장 좋은 근본적인 치료방법으로 알려져 있다. 대상 및 방법: 2001년 1월에서 2005년 12월 사이에 11명의 환자에서 폐동맥 내막절제술을 시행하였다. 모든 환자는 만성적인 호흡곤란과 운동불내성(exercise intolerance)을 나타냈다. 진단은 심장초음파, 폐관류스캔, 컴퓨터 단층촬영을 통해 이루어졌다. 수술 전 한 명의 환자를 제외한 모든 환자에서 하대정맥필터를 삽입하였다. 수술은 극저체온상태에서 전신순환정지를 통해 폐동맥의 최대한 원위부까지 내막절제술을 시행하였다. 중등도 이상의 삼첨판 역류증은 수술 중에 판막성형술로 교정하였다. 결과: 수술사망 및 만기사망은 없었다. 우심실수축기압은 수술 전 91 21 mmHg에서 수술

배경 : 활동성 심내막염의 외과적 치료시기에 대해서는 아직 논란의 여지가 있지만 최근에는 조기 수술에 대한 좋은 보고들이 있다. 이에 저자들은 활동성 심내막염에 대한 수술 결과를 수술 전 항생제 사용기간에 따라 분석해 보았다. 대상 및 방법 : 1995년 3월부터 2001년 10월까지 활동성 심내막염으로 삼성서울병원 흉부외과에서 수술 받은 환자 51명에 대해서 후향적으로 분석을 하였다. 남녀 성비는 39：12였고, 평균 연령은 44.5±17.8세(범위 : 13~74세)였다. 감염된 판막은 승모판막이 17례(33.3%), 대동맥판막이 15례(29.4%), 승모판막 및 대동맥 판막이 12례(23.5%), 삼첨판막이 5례(9.8%)였다. 그 중 인공판막 심내막염이 10례(19.6%)였다. 감염 균주는 포도상구균이 19례(37.3%), 연쇄상구균이 17례(33.3%), 장내구균이 3례(5.9%), 진균이 3례(5.9%), 기타균이 5례(9.8%), 균주가 동정되지 않은 경우가 6례(11.8

Background: Extracorporeal membrane oxygenation (ECMO) has become an important treatment modality in pediatric patients with cardiopulmonary failure, but few studies have been conducted in Korea. Methods: We conducted a retrospective review of pediatric patients younger than 18 years who were placed on ECMO between January 2004 and December 2014 at Samsung Medical Center. Results: We identified 116 children on ECMO support. The overall rate of successful weaning was 51.7%, and the survival to di

Background: Extracorporeal life support (ECLS) is widely used in refractory heart or lung failure, and the demand for inter-facility transportation on ECLS is expanding. However, little is known about post-transportation outcomes, the clinical safety of such transportation, or the characteristics of the transported patients. Methods: This was a retrospective review of a 3-year, single-institution experience with inter-facility ECLS transport, as well as a comparative analysis of clinical outcome

Background and Objectives: Stanford type A aortic dissection is a potentially catastrophic event that requires surgical repair, on an emergency basis. The extent of arch repair that should be carried out during emergency surgery of this type is controversial. This study was designed to evaluate the results of arch replacement carried out during acute type A dissection. Subjects and Methods: 28 patients with Stanford type A dissection and who underwent arch replacement between 1995 and 2006 were

To the Editor, Klebsiella species are common pathogens that cause community-onset and hospital-acquired pneumonia, intra-abdominal infections, and bloodstream infections. Infective endocarditis due to Klebsiella species is rare, accounting for less than 1% of cases, and is frequently accompanied by complications and a high in-hospital mortality rate [1]. Moreover, with the emergence of extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae, endocarditis due to ESBL-producing Klebsi
