Although the angiographic rates of in-stent restenosis (ISR) at later months have reduced dramatically with the introduction of drug-eluting stents (DESs), some patients with ISR after implantation of DES present with acute coronary syndrome (ACS). Here, we sought to identify parameters influencing the likelihood of restenosis with ACS presentation after DES implantation. Stented patients (n=3,817) with DESs in the Korea University Anam Hospital percutaneous coronary intervention registry were reviewed retrospectively for inclusion...

The decreased 123I-BMIPP uptake, while having normal perfusion, in the correspondent coronary artery territory is caused by a delayed metabolic recovery after the recovery of perfusion. This phenomenon termed ischemic memory can clearly differentiate vasospastic angina from other chest pain syndromes.

BACKGROUND: Bronchopulmonary sequestration is a congenital abnormality of the primitive foregut. In adults, the typical age at presentation is 20-25 years. CASE REPORT: A 64-year-old female was referred for evaluation of an 8 × 6-cm right lower lobe cystic lesion. Her medical history was significant for recurrent right lower lobe pneumonia requiring multiple hospitalizations. Her physical examination was significant for crackles at the right lung base. Computed tomography (CT) of the chest with contrast showed cystic changes with thickened septation of the medial segment of the right lower lobe lacking distinct visceral pleura and with arterial supply from the anomalous branch of the thoracic aorta arising near the celiac trunk...

A 79-year-old woman with a history of ischaemic heart disease and atrial fibrillation presented to hospital with severe chest pain. Blood tests showed an elevated D-dimer and a rise in troponin I. ECG showed right bundle branch block pattern and T wave inversion in leads V1 to V3, although these changes were present in old ECGs. A chest X-ray was done which was normal. Due to the nature and severity of her pain a CT aortic angiogram was done. This did not show any evidence of aortic dissection or a pulmonary embolism...

BACKGROUND: Depression is strongly linked to increased morbidity and mortality in patients with chronic stable angina; however, its associated healthcare costs have been less well studied. Our objective was to identify the characteristics of chronic stable patients found to have depression and to determine the impact of an occurrence of depression on healthcare costs within 1 year of a diagnosis of stable angina. METHODS AND RESULTS: In this population-based study conducted in Ontario, Canada, we identified patients diagnosed with stable angina based on angiogram between October 1, 2008, and September 30, 2013...

BACKGROUND AND OBJECTIVE: Symptomatic basilar artery stenosis (BAS) is associated with high risk of ischemic stroke recurrence. We aimed to investigate whether statin therapy might prevent the progression of symptomatic BAS and stroke recurrence. METHODS: We retrospectively analyzed the data of patients with acute ischemia with symptomatic BAS, which was assessed using magnetic resonance angiogram (MRA) imaging on admission day, and 1 year later (or the day of the clinical event)...

BACKGROUND: The incidence of venous thromboembolism (VTE) after lung transplantation (LTX) varies significantly across studies. Two studies have suggested that these thrombotic events are associated with a lower posttransplant survival. Herein, we sought to determine the incidence, predictors and impact of VTE on survival after LTX at a quaternary referral center. METHODS: This was a large cohort study of LTX recipients. Key outcome parameters were time to VTE after transplant and survival...

A 56-year-old woman was admitted to our hospital because of amaurosis fugax. The carotid angiogram showed irregularly stenotic lesions of the left and right internal carotid arteries (ICAs), suggestive of dissection. Follow-up evaluation was performed by transoral carotid ultrasonography (TOCU) with contrast enhancement (CE), which yielded better vessel lumen and intramural hematoma visualization than color Doppler imaging. CE-TOCU is useful for evaluating ICA dissections that extends to the high cervical portion...

We report a case of a 47-year-old female who presented with breathlessness and palpitations for two weeks. On clinical evaluation, bilateral pedal edema was noticed. A CT pulmonary angiogram showed a mass in the left atrium causing significant obstruction to cardiovascular outflow. After extensive work-up, the mass was surgically resected. Histopathological findings from the acquired specimen revealed a high-grade leiomyosarcoma with extensive necrosis and heterologous (cartilaginous) differentiation. The early postoperative period was complicated by cardiac tamponade and the patient died on the second postoperative day due to ventricular arrhythmia, shock and multiorgan failure...

BACKGROUND/OBJECTIVE: Contact aspiration has gained growing acceptance in the endovascular stroke therapy. The safety and efficacy data of the novel ARC™ catheter (Medtronic, Irvine, CA) used for intracranial thrombectomy was poorly evaluated. We reported our preliminary results with the ARC™ with regard to angiographic reperfusion, duration of thrombectomy, safety, and clinical outcome at 90 days. METHODS: In a single center series including 20 large-vessel occlusion stroke patients prospectively collected, we retrospectively evaluated the safety and efficacy profiles of the ARC™ intracranial catheter for first-line contact aspiration...

BACKGROUND: A contralateral approach to clip a middle cerebral artery (MCA) aneurysm in case of bilateral intracranial aneurysms reduces surgical time and cost. However, there is a lack of evidence for objective patient selection. In this study, we assessed the change in surgical freedom along the contralateral MCA to provide objective evidence for patient selection. METHODS: Sixteen cadaveric specimens were studied. Through a pterional approach, the surgical freedom was calculated moving distally along the contralateral MCA at 5-mm increments...

Arteriovenous malformations of the temporalis muscle (TM-AVMs) are rare lesions commonly considered as a variant of scalp AVMs. A study was designed in order to analyze TM-AVMs features and to confirm them as a certain entity different from scalp AVMs. Seven TM-AVMs cases (5 from literature plus 2 from our database) were studied. Clinical, epidemiological, radiological, and therapeutic data were analyzed and compared to common scalp AVMs features. All TM-AVMs presented as large soft tumor-like masses on the temporal region (mean diameter: 6 cm)...
