Addison's Disease and Dilated Cardiomyopathy: A Case Report and Review of the Literature.

Addison's disease is often accompanied by a number of cardiovascular manifestations. We report the case of a 30-year-old man who presented with a new onset dilated cardiomyopathy due to Addison's disease. The clinical presentation, treatment, and outcomes of this rare hormone mediated cardiac disorder are reviewed.

The Role of TEE in Diagnosing Hepatopulmonary Syndrome and Cryptogenic Cirrhosis.

In the vast majority of cases, ongoing hypoxemia in a cirrhotic patient is usually hepatopulmonary syndrome (HPS) until proven otherwise; in this case, HPS was suspected prior to any known diagnosis of cirrhosis. This is the first reported case in the literature whereby HPS and cirrhosis were diagnosed after the fact, rather than with the preexisting knowledge of liver cirrhosis.

Curriculum Development and Evaluation of a Hemodynamic Critical Care Ultrasound: A Systematic Review of the Literature.

Objective: The application of ultrasound to assess a patient's cardiac function and volume status is becoming commonplace in the practice of critical care. These skills have been taught through varying curricula; however, no consensus on the optimal curriculum has been established. The purpose of this systematic review is to evaluate the literature regarding critical care ultrasound curriculum development and evaluation.

Functional mitral regurgitation: current understanding and approach to management.

Functional mitral regurgitation (FMR) is a challenging clinical entity that frequently complicates ischemic and nonischemic cardiomyopathy. The underlying pathophysiology of FMR is caused primarily by ventricular and subvalvular apparatus dysfunction which causes failure of proper leaflet coaptation. Echocardiography is the primary modality used in diagnosis and characterization of FMR.

Carotid intima-media thickness measurements are not affected by the ultrasound frequency.

Objective: Carotid intima-media thickness (IMT) is a B-mode ultrasound measure of subclinical atherosclerosis predictive of future cardiovascular risk. Carotid IMT measurements were historically obtained at an ultrasound frequency of 8 MHz or lower, but it is unknown whether measurements obtained at higher frequencies using newer, more advanced ultrasound technology allow for valid comparison to the older general population databases that are commonly used for the interpretation of carotid IMT results.

Methods: Carotid IMT studies were conducted in 35 consecutive patients at standard (8 MHz) and high (14 MHz) frequencies and measurements were performed by two independent expert readers.

Evaluating the effectiveness of rosuvastatin in preventing the progression of diastolic dysfunction in aortic stenosis: A substudy of the aortic stenosis progression observation measuring effects of rosuvastatin (ASTRONOMER) study.

Background: Tissue Doppler imaging (TDI) is a noninvasive echocardiographic method for the diagnosis of diastolic dysfunction in patients with varying degrees of aortic stenosis (AS). Little is known however, on the utility of TDI in the serial assessment of diastolic abnormalities in AS.

Objective: The aim of the current proposal was to examine whether treatment with rosuvastatin was successful in improving diastolic abnormalities in patients enrolled in the Aortic Stenosis Progression Observation Measuring Effects of Rosuvastatin (ASTRONOMER) study.

Idiopathic ventricular fibrillation controlled successfully with phenytoin.

We describe a case of an individual with idiopathic ventricular fibrillation whose arrhythmias were successfully controlled with phenytoin therapy.

Myocardial siderosis due to hemochromatosis in an individual with hypertrophic cardiomyopathy.

A patient with hypertrophic cardiomyopathy (HCM) and transfusion-dependent sideroblastic anemia, who presented with decompensated heart failure, is described. The present case demonstrates the usefulness of cardiac magnetic resonance imaging as a noninvasive imaging modality to assess the etiology of new systolic dysfunction in the setting of HCM. Cardiac magnetic resonance imaging is able to differentiate between the dilated 'burned-out' phase of HCM and a concomitant dilated cardiomyopathy secondary to myocarditis or hemosiderosis.

Clinical utility of cardiac magnetic resonance imaging in Churg-Strauss syndrome: case report and review of the literature.

We describe a case of an individual with Churg-Strauss syndrome who presented with a cerebrovascular accident (CVA) secondary to left ventricular intracavitary thrombi. Noninvasive cardiovascular imaging using transthoracic echocardiography (TTE) and cardiac magnetic resonance (CMR) was used to identify the cardioembolic source of CVA. The clinical utility of CMR in the management of patients with Churg-Strauss syndrome is reviewed.

Reperfusion times for ST elevation myocardial infarction: a prospective audit.

Background: New published guidelines recommend treatment of ST elevation myocardial infarction (STEMI) within 30 minutes of first medical contact to thrombolysis and 90 minutes to primary percutaneous coronary intervention (PCI).

Objectives: To determine how a tertiary care center compares to these new guidelines and to evaluate the success of measures directed to shorten delays.

Methods: This was a prospectively designed audit loop using retrospective chart review.

Chiari network endocarditis: not just an innocent bystander.

A Chiari's network, noted in approximately 2% of the general population, is a congenital remnant of the sinus venosum valve present in the right atrium. We report a case of a 67-year-old male who presented with acute infective endocarditis of the tricuspid valve due to coagulase-negative Staphylococci. Despite appropriate antimicrobial therapy for 2 weeks, the patient remained febrile with septic emboli to the pulmonary vasculature.

Association of mitral annular calcification and aortic valve morphology: a substudy of the aortic stenosis progression observation measuring effects of rosuvastatin (ASTRONOMER) study.

Aims: Mitral annular calcification (MAC) is characterized by calcium and lipid deposition in the annular fibrosa of the mitral valve. Although individuals with MAC are at increased risk of cardiovascular events, little is known about the significance of this finding in patients with concurrent aortic stenosis (AS). The aim of this study was to describe the association of baseline MAC and aortic valve morphology in asymptomatic patients enrolled in the ASTRONOMER study, a multicentre study to assess the effect of Rosuvastatin on the progression of AS.

Resolution of protein-losing enteropathy with low-molecular weight heparin in an adult patient with Fontan palliation.

Protein-losing enteropathy is a well-known complication after the Fontan procedure, and unfractionated heparin therapy has been tried with some success as a potential therapy. Low-molecular weight heparin is believed to be ineffective. We now describe a case in which an adult patient with protein-losing enteropathy after Fontan palliation was successfully treated with systemic doses of low-molecular weight heparin, with complete resolution in the 24-hour fecal alpha-1 anti-trypsin level and serum albumin.

Intermittent androgen suppression in prostate cancer: an update of the Vancouver experience.

Introduction: This report will review the long-term follow-up of a prospective Phase II evaluation of intermittent androgen suppression in the treatment of prostate cancer. Specifically, this analysis will address completed cycle characteristics, the concept of prolonged off-treatment cycles, the time to cancer progression, cancer-specific survival and the association between PSA and bone scan changes.

Methods: A total of 102 patients have been entered into this protocol.
