Catheterization and Cardiovascular Interventions

BACKGROUND: Same day discharge (SDD) following chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has received limited study. METHODS: We evaluated the clinical, angiographic, and procedural characteristics of patients discharged the same day versus those kept for overnight observation in the Prospective Global Registry for the Study of Chronic Total Occlusion Intervention (PROGRESS-CTO, NCT02061436). RESULTS: Of the 7181 patients who underwent CTO PCI, 943 (13%) had SDD...

Near-infrared spectroscopy (NIRS) is an intravascular imaging (IVUS) modality that detects lipid core plaques in the vessel wall, which are regarded as high-risk plaques for distal embolization in percutaneous coronary interventions (PCI). Saphenous vein graft (SVG) lesions have friable lipid-rich plaques and thrombus prone to distal embolization. The plaque characterization of SVG by NIRS was confirmed herein for the first time with histopathology before and after PCI. The present case was a man in his 60 s with a history of coronary artery bypass graft surgery...

OBJECTIVES: In this study, we aimed to investigate the vascular response to an intravascular lithotripsy (IVL) shockwave balloon in a healthy porcine coronary artery model. BACKGROUND: IVL is a novel clinical technique for modifying heavily calcified atherosclerotic plaques. METHODS: A total of 24 porcine coronary arteries were treated with IVL or plain old balloon angioplasty (POBA). Histology, histomorphometry, quantitative coronary angiography analysis (QCA), and optical coherence tomography (OCT) were performed postprocedure and at 1-month follow-up (1M-FU)...

OBJECTIVES: We aimed to evaluate the diagnostic accuracy of quantitative flow ratio (QFR) in left main (LM) coronary stenoses, using Fractional Flow Reserve (FFR) as reference. BACKGROUND: QFR has demonstrated a high accuracy in determining the functional relevance of coronary stenoses in non-LM. However, there is an important paucity of data regarding its diagnostic value in the specific anatomical subset of LM disease. METHODS: This is a retrospective, observational, multicenter, international, and blinded study including patients with LM stenoses...

AIMS: To compare outcomes of patients who underwent left atrial appendage occlusion (LAAO) for nonvalvular atrial fibrillation (NVAF) and contraindication to anticoagulants due to history of either gastrointestinal (GI) or intracranial (IC) bleeding. METHODS: Patients with NVAF that underwent LAAO for GI or IC bleeding from seven centers were included in this observational study. Baseline characteristics, procedural features, and follow-up data were collected, and compared between the two groups...

BACKGROUND: Invasive procedures used to manage intravascular masses such as vegetation from endocarditis, deep vein thrombosis, and septic emboli are associated with high rates of complications and mortality, especially in patients with several pre-existing comorbidities. A minimally invasive technique that has become more popular in recent years is the AngioVac procedure. This single-centered, retrospective study focuses on patient presenting comorbidities and indications for the procedure as well as postprocedural outcomes...

BACKGROUND: With expansion of transcatheter aortic valve implantation (TAVI) into younger patients, valve durability is critically important. AIMS: We aimed to evaluate long-term valve function and incidence of severe structural valve deterioration (SVD) among patients ≥ 10-years post-TAVI and with echocardiographic follow-up at least 5-years postprocedure. METHODS: Data on patients who underwent TAVI from 2007 to 2011 were obtained from the UK TAVI registry...

BACKGROUND: Endovascular peripheral vascular intervention (PVI) has become the primary revascularization technique used for peripheral artery disease (PAD). Yet, there is limited understanding of long-term outcomes of PVI among women versus men. In this study, our objective was to investigate sex differences in the long-term outcomes of patients undergoing PVI. METHODS: We performed a cohort study of patients undergoing PVI for PAD from January 1, 2010 to September 30, 2015 using data in the Vascular Quality Initiative (VQI) registry...

BACKGROUND: Angiography-derived fractional flow reserve (FFR) (angio-FFR) has been validated against FFR and could provide virtual pullback. However, whether a physiological map can be generated by angio-FFR and its clinical value remains unclear. We aimed to investigate the feasibility of physiological map created from angio-FFR pullback and its value in predicting physiological and clinical outcomes after stenting. METHODS: An angio-FFR physiological map was generated by overlaying the virtual pullback onto coronary angiogram, to calculate physiological stenosis severity, length, and intensity (Δangio-FFR/mm)...

Patients with Marfan syndrome who present with a dual aortic aneurysm are not uncommon in clinical practice; however, the management of these patients is a significant challenge. We present a unique case of aortic root aneurysm and challenging infrarenal abdominal aortic aneurysm (AAA) with a short and angulated neck. We performed simultaneous repair using the Bentall procedure and ascending aortobiiliac bypass. Endovascular obliteration of the AAA neck and bilateral common iliac arteries was also performed...

Clinical outcomes after non-ST-segment-elevation myocardial infarction (NSTEMI) in patients with (symptom-to-door time [SDT] ≥ 24 h) or without (SDT < 24 h) delayed hospitalization among patients with or without diabetes were compared. From the Korea Acute Myocardial Infarction Registry-National Institute of Health, a total of 4517 patients with NSTEMI who underwent new-generation drug-eluting stents implantation were recruited and they were classified into the diabetes mellitus (DM) and non-DM groups...

OBJECTIVE: This study aimed to explore anatomical and hemodynamic features of atrial septal defect, which was treated by transcatheter device closure late after completion of biventricular circulation in patients with pulmonary atresia and intact ventricular septum (PAIVS) or critical pulmonary stenosis (CPS). METHODS: We studied echocardiographic and cardiac catheterization data, including defect size, retroaortic rim length, single or multiple defects, the presence of malalignment atrial septum, tricuspid and pulmonary valve diameters, and cardiac chamber sizes, in patients with PAIVS/CPS who underwent transcatheter closure of atrial septal defect (TCASD), and compared to control subjects...

Pseudoaneurysm (PA) following carotid endarterectomy (CEA) is a rare and dangerous complication. In recent years endovascular approach has been preferred to open surgery as it is less invasive and reduces complications in an already operated neck, especially cranial nerve injuries. We report a case of large post-CEA PA causing dysphagia, successfully treated by deployment of two balloon-expandable covered stents and coil embolization of the external carotid artery. A literature review dealing with all cases of post-CEA PAs since 2000 treated by endovascular means is also reported...
