Long-Term Clinical Outcomes of Iliac Artery Endovascular Therapy in the Korean Vascular Intervention Society Endovascular Therapy in Lower Limb Artery Diseases (K-VIS ELLA) Registry

Background and Objectives@#Limited data are available regarding long-term clinical outcomes of iliac artery endovascular therapy (EVT) in real-world practice. This study investigated long-term outcomes according to Trans-Atlantic Inter-Society Consensus (TASC) classifications. @*Methods@#We analyzed data from 1,705 limbs of 1,364 patients from the retrospective cohort of the multicenter Korean Vascular Intervention Society Endovascular Therapy in Lower Limb Artery Disease registry. The primary endpoint was target lesion revascularization (TLR)-free survival. @*Results@#TASC A, B, C, and D lesions were present in 19.4%, 26.2%, 28.7%, and 25.7% of the treated limbs, respectively. The technical success rate was 96.2% and did not differ between TASC lesion types. Complications occurred in 6.8% of cases and more occurred in TASC D (11.8%). Iliac artery EVT showed a 5-year TLR-free survival of 89.2%. The TASC D group had the lowest TLR-free rate of 79.3%. TASC D (hazard ratio [HR], 1.75; 95% confidence interval [CI], 1.12–2.73; p=0.014), plain old balloon angioplasty (HR, 4.25; 95% CI, 2.03–8.88; p<0.001), current smoker (HR, 1.89; 95% CI, 1.26–2.83; p=0.002), previous bypass surgery (HR, 3.04;95% CI, 1.28–7.19; p=0.011), combined femoropopliteal treatment (HR, 4.89; 95% CI, 3.19–7.50; p<0.001), combined below the knee treatment (HR, 2.20; 95% CI, 1.25–3.89; p=0.007), and complications (HR, 1.86; 95% CI, 1.07–3.24; p=0.028) were predictors for TLR. @*Conclusions@#Iliac artery EVT achieved excellent technical success and 5-year TLR-free survival. TASC D showed a favorable but lower 5-year TLR-free survival rate and higher complication rate compared with other TASC groups.

Successful Primary Percutaneous Coronary Intervention without Stenting: Insight from Optimal Coherence Tomography

For patients with acute myocardial infarction, current management guidelines recommend implantation of a drug-eluting stent, dual antiplatelet therapy (including potent P2Y 12 inhibitors) for at least 1 year, and maintenance of life-long antiplatelet therapy.However, a pilot study showed favorable results with antithrombotic therapy without stent implantation when plaque erosion, not definite plaque rupture, was confirmed using optical coherence tomography (OCT), despite the patients having acute myocardial infarction. Here, we present a case where successful primary percutaneous coronary intervention was performed without stenting with the aid of OCT in a patient with ST-elevation myocardial infarction who developed thrombotic total occlusion of the right coronary artery.

Current State and Strategy for Establishing a Digitally Innovative Hospital - Memorial Review Article for Opening of Yongin Severance Hospital -

The emergence of new technologies, especially digital transformation, influences the entire society, including the medical aspects. Therefore, the concept of digital hospital has been emerging. Here we present the Yongin Severance Hospital, which has developed various novel solutions to serve as foundations for the establishment of a digitally innovative hospital. Further strategies have also been provided to implement consistent and long-term planning.

ST-Segment Elevation Myocardial Infarction as a Result of Coronary Artery Ectasia-Related Intracoronary Thrombus in a Patient with Liver Cirrhosis / 대한중환자의학회지

Coronary artery ectasia (CAE) is a rare condition defined as the dilatation of coronary artery to at least 1.5 times larger than the normal adjacent coronary artery. Clinical manifestations of CAE vary, ranging from asymptomatic to ST-segment elevation myocardial infarction (STEMI). Because of its rarity and clinical diversity, the best treatment strategy and prognosis for CAE remain unclear. We describe a case of STEMI caused by intracoronary thrombus formation within an ectatic area in a patient with liver cirrhosis (LC). The patient was successfully managed by thrombus aspiration only, without balloon angioplasty or stent implantation, and maintained by dual antiplatelet therapy with aspirin and ticagrelor, a potent new P2Y12 inhibitor.

Prediction of the Response to Proton Pump Inhibitor Treatment Using Wireless Ambulatory pH Monitoring in Patients with Globus Sense / 대한소화기학회지

BACKGROUND/AIMS: Globus is a persistent or intermittent non-painful sensation of a lump or foreign body in the throat and a commonly encountered clinical condition. We aim to evaluate the prevalence of gastroesophageal reflux disease (GERD) and to determine the parameters for predicting the response to treatment with proton pump inhibitor (PPI) using wireless pH monitoring in patients with globus sense. METHODS: We retrospectively reviewed the medical records of 37 patients with atypical GERD symptoms. A total of 27 patients with dominant globus sense were enrolled. Endoscopic examination and 48-hour wireless esophageal pH monitoring were performed, and the patients underwent a therapeutic trial of full dose PPIs daily over a period of 4 weeks. RESULTS: Both typical and atypical GERD symptoms co-existed in 14 patients (51.9%, 14/27). According to ROME III criteria, 19 patients (70.4%, 19/27) were diagnosed as GERD. Twelve patients (44.4%, 12/27) were PPI responders. A significant difference in the frequency of symptom index (+) or symptom associated probability (+) was observed between the PPI responder group and the non-responder group (p<0.01). CONCLUSIONS: In patients with globus sense, 70.4% were diagnosed with GERD. Symptom index/symptom associated probability in wireless ambulatory pH monitoring was a good objective parameter for PPI responder.

Early Repolarization Syndrome with Idiopathic Ventricular Fibrillation / 이화의대지

Early repolarization is a common electrocardiographic (ECG) feature found in young adults, men and athletes, and has been considered to be a benign feature for the last several decades. But recent studies suggest that early repolarization may be related to idiopathic ventricular fibrillation and sudden cardiac death. We report a young man, 35 years old, who had life threatening ventricular fibrillation and sudden cardiac arrest. He was evaluated for cardiac causes of ventricular fibrillation. There was no explanation other than that his ECG showed an early repolarization pattern so we treated him with implantable cardioverter defibrillator. Thus, we suggest that early repolarization may be related with life threatening ventricular arrhythmia.

Case of Multiple Cranial Diabetic Neuropathies Involving the Third, Fourth and Sixth Cranial Nerves / 대한내과학회지

Multiple simultaneous cranial neuropathies occur rarely in diabetes patients. In general, diabetic cranial neuropathy presents in an isolated form and frequently involves oculomotor or facial nerves. We report a 73-year-old man with known type 2 diabetes mellitus who presented with severe dizziness, diplopia and third, fourth and sixth nerve ophthalmoplegia of both eyes. Radiological, laboratory and ophthalmic work-up including magnetic resonance imaging and angiography (MRI and MRA) revealed no specific tumor, aneurysm, or inflammation findings, except for a previous cerebral infarction and atherosclerotic changes in the internal carotid and vertebral arteries. After strict blood glucose control, the multiple cranial nerve palsies spontaneously resolved in 12 weeks. We report the case with a review of the literature.
