Congenital Absence of Superior Vena Cava with no Manifestation of Superior Vena Cava Syndrome

Chan,Soon,Park,Jeong,Jae,Kim,Jin,Joo,Park 대한심장학회 2016 Korean Circulation Journal Vol.46 No.5

Total absence of superior vena cava (SVC) is a very rare anomaly, and the patient usually suffers from SVC syndrome or conduction disturbances. We report an asymptomatic 27 year-old male, with complete absence of SVC. Transthoracic echocardiography and computed tomography demonstrated the absence of SVC and other congenital cardiac anomalies, but the presence of prominent collateral vessels that allow a sufficient venous return.

Thrombotic Occlusion of Stent Graft Limbs due to Severe Angulation of Aortic Neck in Endovascular Repair of Abdominal Aortic Aneurysm

Minsu,Kim,Myeong,Gun,Kim,Woong,Chol,Kang,Pyung,Chun,Oh,Ji,Yeon,Lee,Jin,Mo,Kang,Wook-Jin,Chung,Eak,Kyun,Shin 대한심장학회 2016 Korean Circulation Journal Vol.46 No.5

Endovascular aneurysm repair (EVAR) is a safe alternative to open surgical repair for an abdominal aortic aneurysm. However, unfavorable aortic anatomy of the aneurysm has restricted the widespread use of EVAR. Anatomic limitation is most often related to characteristics of the proximal neck anatomy. In this report, we described a patient with a severely angulated proximal neck who underwent EVAR, but required repeat intervention because of thrombotic occlusion of stent graft limbs.

Coronary stent dislodgement is a rare and serious complication of percutaneous coronary intervention and is associated with major adverse cardiac events. Successful retrieval of the stent is recommended in this situation because it is important for the prognosis. Recently, a patient was referred to our hospital with a dislodged coronary stent. When attempting to percutaneously extract the dislodged stent, a challenging situation was encountered, as the stent was entrapped and tightly entangled with another fully deployed coronary stent. Extraction of a fully deployed stent is generally prohibited as it may result in severe complications. Nevertheless, we extracted both the dislodged stent and the fully deployed stent, as a last resort. Herein, we report about this case. Our case highlights if the operator had a thorough understanding of the surrounding circumstances regarding the fully deployed coronary stent, successful extraction of the fully deployed coronary stent without any complications could be possible.

Combined Subpectoral Implantation of Implantable Cardioverter-Defibrillator and Augmentation Mammoplasty in a Young Female Patient

Dong-Jun,Kim,Jae-Sun,Uhm,Je,Wook,Park,Jong-Chan,Youn,Dong,Won,Lee,Moon-Hyoung,Lee,Bon-Nyeo,Koo 대한심장학회 2016 Korean Circulation Journal Vol.46 No.5

Subcutaneous implantation of a cardiac implantable electronic device is the standard method. Occasionally, subpectoral cardiac implantable electronic device (CIED) implantation via axillary incisions is performed in young female patients for cosmetic purposes. Because subpectoral CIED implantation and augmentation mammoplasty involve the same layer, it is feasible to perform both procedures simultaneously. We report a case of combined subpectoral implantation of an implantable cardioverter-defibrillator and augmentation mammoplasty via the axillary approach in a young female patient with dilated cardiomyopathy and small breasts.

Concordant and Discordant Cardiac MRI Delayed Hyperenhancement Pattern in Ischemic and Non-ischemic Cardiomyopathy

Eun,Kyoung,Kim,장성아,최진오,James,Glockner,Brian,Shapiro,Yeon,Hyeon,Choe,Nowell,Fine,장신이,김성목,Wayne,Miller,이상철,Jae,K.,Oh 대한심장학회 2016 Korean Circulation Journal Vol.46 No.1

Background and Objectives: The diagnosis of ischemic (ICM) and non-ischemic cardiomyopathy (NICM) is conventionally determined by the presence or absence of coronary artery disease (CAD) in the setting of a reduced left systolic function. However the presence of CAD may not always indicate that the actual left ventricular (LV) dysfunction mechanism is ischemia, as other non-ischemic etiologies can be responsible. We investigated patterns of myocardial fibrosis using delayed hyperenhancement (DHE) on cardiac magnetic resonance (CMR) in ICM and NICM. Subjects and Methods: Patients with systolic heart failure who underwent a CMR were prospectively analyzed. The heart failure diagnosis was based on the modified Framingham criteria and LVEF <35%. LV dysfunction was classified as ICM or NICM based on coronary anatomy. Results: A total of 101 subjects were analyzed; 34 were classified as ICM and 67 as NICM. The DHE pattern was concordant with the conventional diagnosis in 27 (79.4%) of the patients with ICM and 62 (92.5%) of the patients with NCIM. A discordant NICM DHE pattern was present in 8.8% of patients with ICM, and an ICM pattern was detected 6.0% of the patients with NICM. Furthermore, 11.8% of the patients with ICM and 1.5% of those with NICM demonstrated a mixed pattern. Conclusion: A subset of patients conventionally diagnosed with ICM or NICM based on coronary anatomy demonstrated a discordant or mixed DHE pattern. CMR-DHE imaging can be helpful to determine the etiology of heart failure in patients with persistent LV systolic dysfunction.

Comparison of Transcatheter Atrial Septal Defect Closure in Children, Adolescents and Adults: Differences, Challenges and Short-, Mid- and Long-Term Results

Turkay,Saritas,Ilker,Kemal,Yucel,Ibrahim,Halil,Demir,Fadli,Demir,Abdullah,Erdem,Ahmet,Celebi 대한심장학회 2016 Korean Circulation Journal Vol.46 No.6

Background and Objectives: This study aims to compare the characteristics, effectiveness and results of transcatheter closure of atrial septal defect between children, adolescents, and adults. Subjects and Methods: In this study, 683 patients who underwent atrial septal defect closure in the last 10 years were divided into three groups: children (age <12), adolescents (age 12 to 16), and adults (age >16) as group 1, group 2 and group 3, respectively. Results: The average defect size and incidence of complex atrial septal defect were higher in group 3 (p=0.0001 and 0.03 respectively). While the average size of the devic was higher in adults (22.6±6.4 mm vs. 18.5±4.9 mm; p=0.0001), the ratio of the device size/total septum was higher in both children and adolescents (Group 1 and 2). In the child and adolescent groups and patients with only complex atrial septal defect, the use of techniques, other than standard deployment, was similar in all three groups (p=0.86 and 0.41, respectively). The ratio of the residual shunt was similar in all three groups. Major complications were seen in 5 cases (4 cases with migration, and 1 case with dislocation) in group 3 and 1 case (migration) in group 1. Conclusion: Depending on the complexity of the defect and age of the patient, transcatheter closure of atrial septal defect might have certain difficulties and complications. Patients must be evaluated in detail to avoid major complications and possible problems during the procedure.
