A Very Unusual Origin of Left Subclavian Artery
ABSTRACT: The left internal mammary artery, a branch of the left subclavian artery, is the most commonly used arterial graft during coronary artery bypass grafting. Although extremely rare, an abnormal origin of left subclavian artery may lead to a d…
Utilization of 3 Amplatzer Occluders for Closure of Post-Myocardial Infarction Ventricular Septal Defect
ABSTRACT: This case report describes a patient who sustained a post-myocardial infarction ventricular septal defect (VSD) with an associated left ventricular aneurysm who developed cardiogenic shock and required an intra-aortic balloon pump for hemod…
Acquired (Post-Angioplasty) Coronary Ventricular Fistula Draining into Left Ventricle Aneurysm
ABSTRACT: Coronary artery fistula is a rare condition where a fistulous communication exists between the coronary artery and a cardiac chamber or vein. Mostly they are of congenital origin, but rarely may be acquired due to trauma, post cardiac surge…
Redirection of Anomalous Venous Pulmonary Flow to Left Atrium Using a Vascular Plug II
ABSTRACT: An 8-year-old male patient was sent to the catheterization laboratory for assessment of a partial anomalous pulmonary venous connection found by echocardiography. During the intervention, cineangiogram revealed left pulmonary veins draining…
Exclusion of Infected Pseudoaneurysm of Modified Blalock Taussig Shunt Using a Covered Stent
ABSTRACT: A pseudoaneurysm due to infection after a modified Blalock-Taussig shunt is a rare but potentially fatal complication that can rupture, compress mediastinal structures, produce shunt occlusion, and bacteremia. In these patients, medical man…
Segmental Diastolic Compression of Circumflex Coronary Artery Secondary to Pericardial Constriction: An Uncommon Cause of Angina Pectoris
ABSTRACT: Diastolic segmental compression of a native coronary artery is an uncommon cause of chest pain. Here we describe a 24-year-old woman with constrictive pericarditis who had retrosternal chest pain, progressive dyspnea, tachycardia, and bilat…
An Angiographic Consideration Prior to Coronary Bypass Graft Surgery: Importance of Routine Selective Angiography of the Internal Mammary Artery Prior to Myocardial Revascularization
ABSTRACT: The collateral perfusion via the hypertrophied internal thoracic arteries and rich anastomosis between the epigastric arteries reconstituting femoral artery are an important route in patients with peripheral vascular disease (chronic aortoi…
Editor's Message
Dear Readers,The goal of the Journal of Invasive Cardiology is to provide state-of-the-art information that will support clinicians in the effective management of patients with cardiovascular disease. There are many selections in this issue that I ho…
A Tale of Two Balloons: Assessment of Hemodynamics with Atrial Septal Defect Temporary Balloon Occlusion
Abstract: We describe two cases in which temporary balloon occlusion (TBO) was used to determine the suitability of atrial septal defect (ASD) closure. These cases underscore the utility of TBO in select patients undergoing percutaneous closure of AS…
Pitfalls of Angiography in the Assessment of Atherosclerosis: The Role of Optical Coherence Tomography
Abstract: We report the case of a patient presenting with unstable angina, in whom information obtained by coronary angiography was inconclusive for the existence of a culprit lesion in the ostium of the right coronary artery. The use of optical cohe…
