Diagnosis of Coronary Artery Fistulas: Clinical Aspects and Brief Review of the Literature - Sharma, Umesh M.; Aslam, Ahmed F.; Tak, Tahir
An 86-year-old woman with history of hypertension, diabetes, hyperlipidemia, and coronary artery disease was admitted with new-onset congestive heart failure and pneumonia. She underwent coronary angiography after suffering a non-ST elevation myocardial infarction. There was severe coronary artery disease in addition to coronary artery-pulmonary fistulas involving proximal right coronary artery and a branch of left main coronary artery.
Rotational Atherectomy in a Patient with Acute ST-Elevation Myocardial Infarction and Cardiogenic Shock - Showkathali, Refai; Sayer, Jeremy W.
Rotational atherectomy (rotablation) of coronary artery is relatively contraindicated in high thrombotic state such as acute ST-elevation myocardial infarction (STEMI) because of the risk of platelet activation by the rotablator. We present a case where rotablation was necessary to recanalize the right coronary artery in a patient presenting with acute STEMI complicated by cardiogenic shock, after unsuccessful attempts with balloon catheters. He improved remarkably after the procedure and was discharged after 4 days.
Association of Heart Block with Uncommon Disease States - Yahalom, Malka; Roguin, Nathan; Antonelli, Dante; Suleiman, Khaled; Turgeman, Yoav
A variety of diseases, other than the common Lev-Lenègre disease, are associated with cardiac conduction system abnormalities. These include acute processes, such as acute rheumatic fever, and other disorders, such as sarcoidosis, connective tissue disorders, neoplasms, and bacterial endocarditis with cardiac abscess formation. The purpose of the study is to raise awareness of these rare conditions. We present 10 adult patients (4 males and 6 females) with a mean age of 47 years (range: 19-69), with various rare diseases associated with heart block, who needed temporary or permanent pacemaker therapy in the past two decades. These conditions included acute rheumatic...
Adverse Reactions to Iodinated Contrast Media - Bottinor, Wendy; Polkampally, Pritam; Jovin, Ion
The use of iodinated contrast agents for angiography dates back to the 1920s. With over 75 million contrast-requiring procedures performed annually worldwide, it is important to understand the risk factors, pathogenesis, diagnosis, prevention, and treatment of adverse reactions caused by iodinated contrast media (ICM). As contrast media have evolved from ionic, high-osmolality to nonionic, low-osmolality formulations the risk of reactions has decreased over time; however, no pretreatment protocol has been shown to eliminate all repeat reactions. Clinical alertness and early recognition of adverse reactions is of paramount importance and key for appropriate management of these patients. In this article, we...
Pulmonary Artery Aneurysms: Four Case Reports and Literature Review - Theodoropoulos, Panagiotis; Ziganshin, Bulat A.; Tranquilli, Maryann; Elefteriades, John A.
Aneurysms of the pulmonary artery are proven to be a very rare entity. Association with structural cardiac anomalies, structural vascular anomalies, pulmonary hypertension, vasculitis, and infection has been noted. Surgical intervention of symptomatic aneurysms is recommended. A more detailed study of the natural history of these aneurysms is needed. Here, we report four cases of pulmonary artery aneurysms as well as a brief review of the literature existing on this subject. The first case is of a 41-year-old woman with the aneurysm located 1 cm distal to the pulmonary valve extending to the bifurcation of the main pulmonary artery. The...
Accuracy of Duplex Ultrasonography in Estimation of Severity of Peripheral Vascular Disease - Franz, Randall W.; Jump, Mark A.; Spalding, M. Chance; Jenkins, James J.
Duplex ultrasonography (DUS) is a safe, noninvasive method for imaging vasculature when compared with conventional angiography. Our goal is to assess the accuracy of DUS compared with angiography of the lower extremities. We reviewed a total of 373 lesions in 278 patients from July 2005 through June 2010. Patients underwent DUS followed by angiography within 30 days. Peak systolic velocities (PSV) were stratified into one of four categories and compared with the angiographic findings. Seventy-five chronic total occlusions were found. Of the remaining 298 lesions, a significant relationship was found between PSV and degree of angiographic stenosis (p < 0.001)....
Coronary Sinus Ostial Atresia and Persistent Left-Sided Superior Vena Cava: Clinical Significance and Strategies for Cardiac Resynchronization Therapy - Lim, Paul Chun Yih; Baskaran, Lohendran; Ho, Kah Leng; Teo, Wee Siong; Ching, Chi Keong
A 48-year-old male patient underwent cardiac resynchronization therapy defibrillator implantation, and he was found to have atresia of the coronary sinus ostium with venous drainage occurring via a persistent left-sided superior vena cava, which was connected to the right-sided superior vena cava by the innominate vein. This is a rare benign cardiac anomaly that can pose problems when the coronary sinus needs to be cannulated. To identify the course of the coronary sinus, a coronary angiogram can be performed with attention directed to the venous phase of the angiogram. Although the technical difficulty of coronary sinus cannulation increases, various catheters,...
Outcomes of Patients Treated with the Everolimus- versus the Paclitaxel-Eluting Stents in a Consecutive Cohort of Patients at a Tertiary Medical Center - Shammas, Nicolas W.; Shammas, Gail A.; Nader, Elie; Jerin, Michael; Mrad, Luay; Ehrecke, Nicholas; Shammas, Waheeb J.; Voelliger, Cara M.; Hafez, Alexander; Kelly, Ryan; Reynolds, Emily
In this study, we compare the outcomes of the paclitaxel-eluting stent (PES) versus the everolimus-eluting stent (EES) treated patients at a tertiary medical center and up to 2 years follow-up. Unselected consecutive patients were retrospectively recruited following stenting with PES (159 patients) or EES (189 patients). The primary endpoint of the study was target lesion failure (TLF), defined as the combined endpoint of cardiac death, nonfatal myocardial infarction (MI), or target lesion revascularization (TLR). Secondary endpoints included target vessel revascularization (TVR), TLR, target vessel failure (TVF), acute stent thrombosis (ST), total death, cardiac death, and nonfatal MI. Patients treated with...
A Rare Case of Behçet Disease Presenting with Pyrexia of Unknown Origin, Pulmonary Embolism, and Right Ventricular Thrombus - Xing, Weili; Swaminathan, Girider; Appadorai, Dorai Raj; Sule, Ashish Anil
Behçet disease is a systemic vasculitis characterized by recurrent oral and genital ulcers and uveitis. We describe a rare case of a 43-year-old woman with Behçet disease who was admitted for pyrexia of unknown origin, cough, dyspnea, and chest pain. Her computerized tomography scan revealed pulmonary embolism and right ventricular thrombus. She was treated with anticoagulation for pulmonary embolism and right ventricular thrombus. She was well during her last follow-up.
Intercoronary Continuity: A Case Report - Karabay, Kanber Ocal; Bagirtan, Bayram; Gozukara, Ibrahim
Intercoronary continuity is a rare variance of coronary circulation. The importance of this rare anomaly is unknown. We present this rare anomaly in a patient with acute myocardial infarction.
Effect of Short-Term Low-Intensity Exercise Training on Association of Oxygen Free Radicals and Nitric Oxide Production in Patients with Acute Myocardial Infarction - Baraas, Faisal; Rilantono, Lily; Diniharini, Sri; Kurniawan, Iwan; Christian, Roy; Kusmana, Dede
Moderate-to-high intensity of exercise training within 2 to 3 months decreases oxygen free radicals (reactive oxygen species, ROS) and increases nitric oxide (NO) in outpatients with myocardial infarction. There is no data about the association of ROS and NO after short-term low-intensity exercise training within 5 days in patients hospitalized with acute myocardial infarction (AMI). A total of 32 male patients with AMI were randomized into two groups: 15 patients with short-term low-intensity exercise training within 5 days formed the training group and 17 patients without such exercise training formed the control group. All patients performed exercise treadmill test with...
Retrieval of Broken Export Catheter during Primary Angioplasty - Mehta, Vimal; Pandit, Bhagya Narayan; Trehan, Vijay
Broken catheter fragments in a coronary artery during percutaneous coronary interventions although uncommon can potentially result in life-threatening consequences from the attended embolization, thrombus formation, and perforation. We report an unusual complication of a broken export catheter during primary angioplasty, which was successfully managed by inflated balloon-mediated retrieval technique.
Lemierre Syndrome—Should We Anticoagulate? A Case Report and Review of the Literature - Phua, C.K.; Chadachan, V.M.; Acharya, R.
Lemierre syndrome is an uncommon condition classically described in acute oropharyngeal infection with septic thrombophlebitis of the internal jugular vein and metastatic septic embolism particularly to the lungs. It is commonly described in young healthy adults with isolation of Fusobacterium necrophorum. We describe a case of Lemierre syndrome in a 50-year-old man with newly diagnosed diabetes mellitus presenting with a neck abscess secondary to Klebsiella pneumoniae. Our patient made good recovery to appropriate antimicrobial therapy, prompt surgical drainage, and anticoagulation. Anticoagulation remains controversial and we review the literature for its role in Lemierre syndrome.
Posttraumatic versus Mycotic Dorsalis Pedis Pseudoaneurysm - Lynch, James E.; Winkler, Katrina A.; Xenos, Eleftherios
Reports of dorsalis pedis aneurysms are rare, and there are currently no reports of mycotic dorsalis pedis aneurysms in the literature. Most dorsalis pedis pseudoaneurysms are diagnosed by physical exam and color flow duplex. Surgical treatment includes aneurysm resection with or without reconstruction of the dorsalis pedis artery. We report a dorsalis pedis pseudoaneurysm diagnosed clinically and via duplex ultrasound, treated by excision and ligation of the aneurysm.

Kidney transplantation is the preferred clinical and most cost-effective option for end-stage renal disease. Significant advances have taken place in the care of the transplant patients with improvements in clinical outcomes. The optimization of the costs of transplantation has been a constant goal as well. We present herein the impact in financial outcomes of a shortened length of stay after kidney transplant.
A Case Series of HIV-Seropositive Patients and Hypercoagulable State—Is It Difficult to Treat Even with Therapeutic Anticoagulation? - Sule, Ashish Anil; Pandit, Nihar; Handa, Pankaj; Chadachan, Veerandra; Tan, Endean; Sum, Faith Nadine Choo Yun; Joyce, Er Hui Ling; Chin, Tay Jam
Patients with human immunodeficiency virus (HIV) are at risk of developing thrombosis and are 8 to 10 times more likely to develop thrombosis than the general population. Moreover, if they have hypercoagulable state they can have severe thrombosis and life-threatening thrombotic events. The purpose of this retrospective study is to analyze hypercoagulable state in HIV-seropositive patients who have been diagnosed with venous thromboembolism (VTE). This study is a subgroup study of a larger cohort group of HIV-seropositive patients with VTE followed up with our vascular medicine outpatient clinic. The patients included for this study were HIV-seropositive patients with hypercoagulable state,...
Clinical Significance of Conditions Presenting with ECG Changes Mimicking Acute Myocardial Infarction - Yahalom, Malka; Roguin, Nathan; Suleiman, Khaled; Turgeman, Yoav
The electrocardiogram (ECG) is the primary tool in the diagnosis of acute myocardial infarction (AMI). However, other clinical conditions, both cardiac and noncardiac originated pathologies, may result in ECG tracing of AMI. This may lead to an incorrect diagnosis, exposing the patients to unnecessary tests and potentially harmful therapeutic procedures. The aim of this report is to increase the still insufficient awareness of clinicians from multiple disciplines, regarding the different clinical syndromes, both cardiac and noncardiac, associated with ECG abnormalities mimicking AMI, to avoid unjustified thrombolytic therapy or intervention procedures. During a 9-year period, the data from six patients (five...
Endovascular Repair of a Traumatic Thoracic Aortic Injury Resulting in Late Aortic Dilatation - Ozaki, Kumi; Matsui, Osamu; Ohtake, Hiroshi; Watanabe, Go; anada, Junichiro
We present an unusual complication following endovascular repair of traumatic thoracic aortic injury using a homemade stent-graft. Although an initial technical success was apparently obtained, the aorta showed remarkable dilatation without shortening or migration of the stent skeleton in late follow-up period. The possible cause of the dilatation was considered to be the expansion and gathering of the crimped, loosely attached, graft fabric in addition to the incomplete exclusion due to the insufficient landing zone and the limited radial force. Thus, the specific feature of stent-graft, considered to provide an advantage to treatment, has adversely affected the native aorta.
Risk of Venous Thromboembolism in Patients Infected with HIV: A Cohort Study - Sule, Ashish Anil; Pandit, Nihar; Handa, Pankaj; Chadachan, Veerandra; Tan, Endean; Sum, Faith Nadine Choo Yun; Joyce, Er Hui Ling; Chin, Tay Jam
Introduction Human immunodeficiency virus (HIV) patients are at risk of developing thrombosis than general population. There are several intersecting mechanisms associated with HIV infection and antiviral therapy that are emerging, which may lead to vasculopathy and hypercoagulability in these patients.
