Intervention in the Occluded Vein Graft: With High Risk Can Come Great Reward. Review of Techniques With Case Examples
Abstract: Total occlusion of a saphenous vein graft (SVG) can present as abrupt thrombotic occlusion in an atherosclerotic graft with resultant acute cardiac events or chronic total occlusion (CTO) with resultant angina symptoms. The risks of percuta…
Off-Label Closure During CLOSURE Study
Abstract: Background. The role of percutaneous closure of patent foramen ovale (PFO) in patients with cryptogenic stroke or transient ischemic attack remains controversial. Registry data have suggested considerable benefit of closure over medical the…
Intracardiac Aspiration for Life-Threatening Air Embolism During Cardiac Catheterization in Tetralogy of Fallot: An Aborted Sudden Death
ABSTRACT: Accidental introduction of air into veins can occur during a variety of surgical operations or diagnostic procedures. High mortality rate results without early diagnosis and appropriate treatment. This is due to “air lock” at the right vent…
Thrombus Aspiration With Microcatheter for Distal Embolization During Primary Angioplasty for Acute Myocardial Infarction: Technical Notes
Abstract: We describe a new technique for removing distal emboli that became visible on angiography during percutaneous coronary intervention for acute myocardial infarction. Three patients presented with distal embolization as a filling defect with…
Anomalous Origin of the Right Coronary Artery With Intramural Aortic Course Causing Exercise-Induced Cardiac Arrest
A 25-year-old athletic man had a ventricular fibrillation arrest while running. Electrocardiogram after defibrillation showed ST-segment elevations in leads V1 and V2 and incomplete right bundle branch block, which then normalized. Personal and famil…
Direct Aspiration of Large Thrombi in Acute Myocardial Infarction Using a Standard 6 Fr Guide Catheter Via the Transradial Approach
ABSTRACT: A large thrombus load on the culprit coronary artery of patients with acute myocardial infarction (MI) is associated with increased procedural complications and adverse coronary events following angioplasty. This case series describes effec…
Percutaneous Catheter-Based Left Atrial Appendage Ligation and Management of Periprocedural Left Atrial Appendage Perforation With the LARIAT Suture Delivery System
ABSTRACT: We report an 88-year-old male with coronary artery disease, previously placed left main coronary artery drug-eluting stent, and atrial fibrillation unable to tolerate anticoagulation with warfarin in addition to dual antiplatelet therapy wh…
Dislocation of an Infected and Abandoned Pacemaker Lead
ABSTRACT: We present a case of pacemaker lead dislodgment in an 83-year-old patient with a pacemaker infection. Initially, the generator and the proximal part of the leads were removed, and the remaining leads were severed and abandoned. Twenty-five…
Coronary to Bronchial Artery Fistula: Are We Treating It Right?
ABSTRACT: Fistulas between coronary artery and bronchial artery may be present from birth, with few hemodynamic consequences, and may remain closed due to similarity of the filling pressures at these 2 sites.1 They can also be secondary to pulmonary…
Catheter-Induced Bilateral Coronary Ostium Dissection in a Patient with Long-Term Steroid Therapy
ABSTRACT: Catheter-induced coronary dissection is a very rare and serious complication. We report a case of a 44-year-old man with catheter-induced bilateral coronary dissection that occurred during diagnostic coronary angiography for angina. The cor…
