BACKGROUND Dual antiplatelet therapy is recommended after coronary stenting to prevent thrombotic complications, yet the benefits and risks of treatment beyond 1 year are uncertain. METHODS Patients were enrolled after they had undergone a coronary stent procedure in which a drug-eluting stent was placed. After 12 months of treatment with a thienopyridine drug (clopidogrel or prasugrel) and aspirin, patients were randomly assigned to continue receiving thienopyridine treatment or to receive placebo for another 18 months; all patients continued receiving aspirin. The coprimary efficacy end points were stent thrombosis and major adverse cardiovascular and cerebrovascular events (a composite of death, myocardial …

Multi-Detector Coronary Ct Imaging For The Identification Of Coronary Artery Stenoses In A "Real-World" Population, A. N. Makaryus, S. Henry, L. Loewinger, J. N. Makaryus, L. Boxt
Journal Articles
BACKGROUND: Multi-detector computed tomography (CT) has emerged as a modality for the non-invasive assessment of coronary artery disease (CAD). Prior studies have selected patients for evaluation and have excluded many of the "real-world" patients commonly encountered in daily practice. We compared 64-detector-CT (64-CT) to conventional coronary angiography (CA) to investigate the accuracy of 64-CT in determining significant coronary stenoses in a "real-world" clinical population. METHODS: A total of 1,818 consecutive patients referred for 64-CT were evaluated. CT angiography was performed using the GE LightSpeed VCT (GE((R)) Healthcare). Forty-one patients in whom 64-CT results prompted CA investigation were further evaluated, and …

Implications Of Gender Difference In Coronary Calcification As Assessed By Ct Coronary Angiography, A. N. Makaryus, C. Sison, M. Kohansieh, J. N. Makaryus
Journal Articles
BACKGROUND: Arterial calcium as measured by 64-slice computed tomography coronary angiography (64-CT) is a reliable predictor of cardiovascular disease risk. Lipid-rich plaques with lower degrees of calcification may pose greater risk for adverse coronary events than more stabilized calcified plaques as a result of the increased risk of plaque rupture, migration, and subsequent acute coronary syndrome. We sought to examine coronary artery calcium scores as measured via 64-CT to assess the extent of calcification and plaque distribution in women compared to men. METHODS: A total of 138 patients referred for 64-CT were evaluated. Computerized tomographic angiography was performed using the …

Inappropriate Implantable Cardioverter-Defibrillator Shocks Attributed To Alternating-Current Leak In A Swimming Pool, J. N. Makaryus, J. Angert-Gilman, M. Yacoub, A. Patel, B. Goldner
Journal Articles
Implantable cardioverter-defibrillators (ICDs) are the standard of care for preventing sudden cardiac death in patients who are predisposed to malignant ventricular arrhythmias. Causes of inappropriate ICD shock include equipment malfunction, improper arrhythmia evaluation, misinterpretation of myopotentials, and electromagnetic interference. As the number of implanted ICDs has increased, other contributors to inappropriate therapy have become known, such as minimal electrical current leaks that mimic ventricular fibrillation. We present the case of a 63-year-old man with a biventricular ICD who received 2 inappropriate shocks, probably attributable to alternating-current leaks in a swimming pool. In addition, we discuss ICD sensitivity and offer recommendations …

Journal Articles
BACKGROUND: We have developed a novel and practical cardiovascular magnetic resonance (CMR) technique to evaluate left ventricular (LV) mitral annular motion by tracking the atrioventricular junction (AVJ). To test AVJ motion analysis as a metric for LV function, we compared AVJ motion variables between patients with hypertrophic cardiomyopathy (HCM), a group with recognized systolic and diastolic dysfunction, and healthy volunteers. METHODS: We retrospectively evaluated 24 HCM patients with normal ejection fractions (EF) and 14 healthy volunteers. Using the 4-chamber view cine images, we tracked the longitudinal motion of the lateral and septal AVJ at 25 time points during the cardiac …

Takotsubo Cardiomyopathy As A Sequela Of Elective Direct-Current Cardioversion For Atrial Fibrillation, J. S. Siegfried, S. Bhusri, N. Guttenplan, N. L. Coplan
Journal Articles
In takotsubo cardiomyopathy, the clinical appearance is that of an acute myocardial infarction in the absence of obstructive coronary artery disease, with apical ballooning of the left ventricle. The condition is usually precipitated by a stressful physical or psychological experience. The mechanism is unknown but is thought to be related to catecholamine excess. We present the case of a 67-year-old woman who experienced cardiogenic shock caused by takotsubo cardiomyopathy, immediately after undergoing elective direct-current cardioversion for atrial fibrillation. After a course complicated by left ventricular failure, cardiogenic shock, and ventricular tachycardia, she made a complete clinical and echocardiographic recovery In …

Coronary angiography is the gold standard for defining obstructive coronary disease. However, radiation exposure remains an unwanted hazard. Patients referred for coronary angiography with abdominal circumference60 ml/min were randomized to the fluorography (n = 25) or cineangiography (n = 25) group. Patients in the fluorography group underwent coronary angiography using retrospectively stored fluorography with repeat injection under cineangiography only when needed for better resolution per operator's discretion. Patients in the cineangiography group underwent coronary angiography using routine cineangiography. The primary end point was patient radiation exposure measured by radiochromic film. Secondary end points included the radiation output measurement of kerma-area …

Ascending aortic aneurysms involving the proximal aortic arch, arising anywhere from the aortic valve to the innominate artery, represent various problems in which open surgery is generally required. Surgical options include excision of the aortic pathology or wrapping the aneurysm shell with an aortic Dacron graft. Intervention using the latter method can lead to extravasation of blood along the suture lines resulting in continuous bleeding within the periprosthetic space. The Cabrol technique was developed as a method for decompression of postoperative leaks by the formation of a conduit system from the periprosthetic space to the right atrium. The coronary ostia …

Background Recent clinical trials have demonstrated the safety and efficacy of several non-vitamin K oral anticoagulants (NOACs) for the treatment of atrial fibrillation (AF). However, there are limited data on their use and outcomes in routine clinical practice, particularly among patients newly diagnosed as having AF and patients with AF recently transitioned to a NOAC. Methods/Design ORBIT-AF II is a multicenter, national registry of patients with AF that is enrolling up to 15,000 newly diagnosed patients with AF and/or those with AF recently transitioned to a NOAC from 300 US outpatient practices. These patients will be followed for up to …
A Rare Case Of Double-Chambered Right Ventricle Associated With Ventricular Septal Defect And Congenital Absence Of The Pulmonary Valve, G. Khoueiry, T. Bhat, M. Tantray, M. Meghani, N. Abi Rafeh, M. Abdallah, W. Hoyek
A Rare Case Of Double-Chambered Right Ventricle Associated With Ventricular Septal Defect And Congenital Absence Of The Pulmonary Valve, G. Khoueiry, T. Bhat, M. Tantray, M. Meghani, N. Abi Rafeh, M. Abdallah, W. Hoyek
Journal Articles
Double-chambered right ventricle (DCRV) is a rare congenital heart disorder involving 2 different right ventricle (RV) pressure compartments that is often associated with ventricular septal defect (VSD). Usually, the obstruction is caused by an anomalous muscle bundle crossing the RV from the interventricular septum to the RV free wall. We are reporting a case of double-chambered right ventricle associated with ventricular septal defect and congenital absence of the pulmonary valve, a rare form of congenital infundibular pulmonary stenosis. In addition to ventricular septal defect, our patient had congenital absence of the pulmonary valve, which is very unusual and has never …

As the number of patients having implantable cardioverter defibrillator (ICD) devices is increasing, it is important for the physicians and patients to be aware of situations and conditions that can result in interference with normal functioning of these devices. There are multiple cases of malfunction of ICDs reported in literature and it may be of great significance to have an overview of these incidents for appropriate recognition and future prevention. Here we are reviewing the available literature as well as reporting an interesting case of electromagnetic interference (EMI) resulting from leak of current in pool water causing firing of ICD.
