Objectives: To describe medium‐ to long‐term follow‐up of patients undergoing device closure of patent foramen ovale (PFO) for stroke or transient ischemic attack (TIA).
Secundum atrial septum defect (ASD) is the most common congenital heart disease. It is usually treated by a transcatheter approach using a femoral venous access. In case of bilateral femoral vein occlusion, the internal jugular venous approach for ASD closure is an option, in particular in cases where ASD balloon occlusion test and sizing is needed. Here, we report on a new technique for ASD closure using a venous‐arterial circuit from the right internal jugular vein to the femoral artery. Two patients (females, 4 and 10 years of age) had occlusion of both femoral veins because of a previous history of pulmonary atresia and intact ventricular septum, for which they underwent percutaneous radiofrequency perforation and balloon angioplasty. These subjects needed balloon occlusion test of a residual ASD to size the hole and to check for hemodynamic suitability to ASD closure. After performing a venous‐arterial circuit, a 24 mm St Jude ASD sizing balloon catheter was advanced over the circuit and the defect closed for 15 min to check hemodynamics and size the defect. ASD was closed is hemodinamically suitable. This technique was safe and reliable.
Objectives: To evaluate the safety, feasibility, and efficacy of the MVP™ microvascular plug(Covidien) for closure of vascular anomalies in patients with congenital heart diseases (CHD).
We propose a mechanism of how stroke may be caused by thrombus aspiration during primary percutaneous coronary intervention (PPCI), and how it may be technique‐dependent.
As the LCx is closely related to the mitral valve annulus, it is susceptible to perioperative injury. Various underlying mechanisms, predisposing factors, and therapeutic strategies have been suggested but disagreement exists. Using a MeSH terms‐based PubMed search, 44 cases of mitral valve surgery‐related LCx injury were detected, including our 4 cases. We provide a comprehensive review of current knowledge regarding mitral valve surgery‐related left circumflex coronary artery (LCx) injury. Preoperative coronary angiography was performed in 55% (n = 24). Coronary abnormalities were present in 11% (n = 5). Coronary dominance was reported in 73% (n = 32), predominantly showing left (69%, n = 22) or balanced (19%, n = 6) circulations. Right coronary dominance was present in 12% (n = 4). Ischemia was detected in the perioperative or early postoperative phase in 86% (n = 30). Delayed symptoms were present in 14% (n = 5). Echocardiography demonstrated new regional wall motion abnormalities in 80% (n = 24), but was negative in 20% (n = 6) despite coronary compromise. Electrocardiography showed myocardial ischemia in 97% (n = 34), including regional ST‐segment elevations in 68% (n = 23). Primary treatment was surgical in 42% (n = 15) and percutaneous in 58% (n = 21), reporting success ratios of 87% (n = 13) and 81% (n = 17), respectively. We confirm an augmented risk of mitral valve surgery‐related LCx injury in balanced or left‐dominant coronary circulations. Preoperative knowledge of coronary anatomy does not preclude LCx injury. An anomalous LCx arising from the right coronary cusp was identified as a possible specific high‐risk entity. Electrocardiographic monitoring and intraoperative echocardiography remain paramount to ensure a timely diagnosis and treatment.
Objectives: To evaluate the safety and feasibility of subclavian artery stenting for coronary‐subclavian steal syndrome (CSSS).
Background: The safety and efficacy of the second‐generation biodegradable polymer Cobalt‐Chromium sirolimus‐eluting stent (EXCEL2) in daily clinical practice remains unknown. Additionally, to meet the China Food and Drug Administration requirements, we conducted an objective performance criterion study from the CREDIT II and CREDIT III trials.
Background: Implantation of early‐generation metallic drug‐eluting stents (DES) in patients with acute myocardial infarction (AMI) is associated with poor vessel wall healing. Use of biodegradable polymer (BP) DES might improve safety outcomes; however, the impact of varying drug elution and polymer absorption kinetics of BP‐DES on clinical outcomes in the AMI population is unknown.
Objectives: To compare outcomes after minimalist and standard transfemoral transcatheter aortic valve replacement (TF‐TAVR) in patients with severe chronic obstructive pulmonary disease (COPD).
Objectives: To compare indications and clinical outcomes of two contemporary left atrial appendage (LAA) percutaneous closure systems in a “real‐world” population.
Objective. We report our recent experience with the new Occlutech® PDA Occluder, which seems suitable especially for closure of large patent ductus arteriosus (PDA) sizes with elevated pulmonary artery pressure (PAH).
Objective: To determine the short‐ and medium‐term outcomes of ductal stenting (DS) in patients with functionally univentricular hearts (FUHs) and ductal‐dependent pulmonary blood flow.
Aims: To gather current experience in Occlutech ASD device retrieval, to determine whether snaring is an effective technique and to highlight alternative retrieval techniques.
By providing valuable information about the coronary artery wall and lumen, intravascular imaging may aid in optimizing interventional procedure results and thereby could improve clinical outcomes following percutaneous coronary intervention (PCI). Intravascular optical coherence tomography (OCT) is a light‐based technology with a tissue penetration of approximately 1 to 3 mm and provides near histological resolution. It has emerged as a technological breakthrough in intravascular imaging with multiple clinical and research applications. OCT provides detailed visualization of the vessel following PCI and provides accurate assessment of post‐procedural stent performance including detection of edge dissection, stent struts apposition, tissue prolapse, and healing parameters. Additionally, it can provide accurate characterization of plaque morphology and provides key information to optimize post‐procedural outcomes. This manuscript aims to review the current clinical and research applications of intracoronary OCT and summarize the analytic OCT imaging software packages currently available.
This is the first documented case of a drug‐coated balloon strategy for the treatment of bioresorbable in‐scaffold restenosis caused by diffuse neointimal proliferation. This case can provide an alternative treatment option in this setting, avoiding potential problems related to further bulky metallic stents in a patient where a different strategy was initially planned.
