BACKGROUND: Surgical and perioperative improvements permit earlier repair of partial and transitional atrioventricular septal defects (AVSD). We sought to describe contemporary outcomes in a multicenter cohort.

METHODS: We studied 87 patients undergoing primary biventricular repair of partial or transitional AVSD between June 2004 and February 2006 across seven North American centers. One-month and 6-month postoperative data included weight-for-age z-scores, left atrioventricular valve regurgitation (LAVVR) grade, residual shunts, and left ventricular ejection fraction. Paired methods were used to assess 6-month change.

RESULTS: Median age at surgery was 1.8 years; median weight z-score was -0.88. Median days for ventilation were 1, intensive …

Ganglionic Plexus Ablation During Pulmonary Vein Isolation--Predisposing To Ventricular Arrhythmias?, Faizel Osman, Suman Kundu, Jiun Tuan, Jeilan Mohamed, Peter J. Stafford, G. Andre' Ng

Internal Medicine, East Africa

Catheter ablation is increasingly used to treat patients with atrial fibrillation (AF). Ablation of ganglionic plexi is often performed to reduce vagal innervation and has been shown to confer a better long-term outcome in terms of AF recurrence. We report a case of a patient having AF ablation with a profound vagal response, suggesting ganglionic plexus ablation, who subsequently developed ventricular fibrillation after programmed ventricular stimulation. Reduced vagal modulation is known to predispose to ventricular arrhythmias and vagal denervation following AF ablation may predispose to ventricular arrhythmias and requires further study.

Stroke Prevalence In A Poor Neighbourhood Of Sao Paulo, Brazil: Applying A Stroke Symptom Questionnaire, Paulo A. Lotufo

Paulo A Lotufo

Background Brazil has one of the highest stroke mortality rates in the world, these rates are most endemic in the poor. We verified the prevalence of stroke in a deprived neighbourhood in the city of Sa˜ o Paulo, Brazil and compared it with other surveys worldwide. Methods A questionnaire with six questions concerning limb and facial weakness, articulation, sensory disturbances, impaired vision, and past diagnosis of stroke was completed door-to-door in a well-defined area of 15 000 people. Questionnaires were considered positive when a participant answered two or more questions about stroke symptoms or the presence of stroke being confirmed …

An Open Letter To The Citizens Of Northwest Louisiana, Frederick J. White Iii

Frederick J White III

We, the undersigned physicians, want to publicly address our community regarding the health system debate in Congress. This is a historic time, and decisions made in these next days will impact you as citizens and as patients for generations. We recognize that the health system needs change. But the path that the Congress has taken is unwise and unnecessary. And although the American Medical Association has endorsed both the House and Senate bills, (1) we want to be clear—the AMA does not speak for us on these issues.

Acute Subarachnoid Hemorrhage And Cardiac Abnormalities: Takotsubo Cardiomyopathy Or Neurogenic Stunned Myocardium? A Case Report, C Franco, B Khaled, L Afonso, M Raufi

Wayne State University Associated BioMed Central Scholarship

Abstract

Introduction

Cardiac abnormalities can be seen with subarachnoid hemorrhage. To date, there have been isolated case reports of transient left ventricular apical ballooning cardiomyopathy, also known as Takotsubo cardiomyopathy in patients suffering from subarachnoid hemorrhage.

Case presentation

An adult female was brought to the emergency department with somnolence. A 3 × 3 mm ruptured basilar aneurysm was found and successfully embolized. Two days after the patient developed acute heart failure. Troponin-I was elevated to 4.2 (normal <0.4). On ECG, new symmetric T wave inversion in V3, V4, V5 with prolonged QT were evident. Transthoracic echocardiogram showed severe systolic dysfunction with an ejection fraction of 20% and akinetic apex along with the distal left ventricular segments, consistent with Takotsubo cardiomyopathy. Myocardial contrast echocardiography showed a decrease in capillary blood flow and volume in the akinetic areas with delayed contrast replenishment, sparing the basal segments. A repeat study 2 weeks later showed near normalization of the perfusion parameters. The patient improved with medical management. A repeat echocardiogram, a month later revealed an ejection fraction of 45% with no identifiable wall motion abnormality.

Conclusion

Our case, as well as others reported previously, supports the diagnosis of Takotsubo cardiomyopathy in patients with Subarachnoid Hemorrhage who fulfill the …

Diverticular And Aneurysmal Structures Of The Left Ventricle In Adults: Report Of A Case Within The Context Of A Literature Review., Premraj Makkuni, Morris N Kotler, Vincent M. Figueredo

Department of Medical Genetics Faculty Papers

Left ventricular outpouchings are increasingly detected on cardiovascular imaging. Herein, we describe the case of a 45-year-old man who underwent noncardiac preoperative imaging and was found to have an asymptomatic left ventricular outpouching. The patient underwent successful surgical repair of the structure. When left ventricular outpouchings are detected, the main differential diagnoses are pseudoaneurysm, aneurysm, and diverticulum. The outcomes for these conditions differ substantially, and accurate diagnosis can be crucial in making clinical decisions. We review the relevant medical literature, outline the natural history of these left ventricular abnormalities, and discuss options in regard to their management.

Subclinical Hyperthyroidism And Dementia: The Sao Paulo Ageing & Health Study (Spah), Paulo A. Lotufo

Paulo A Lotufo

Background: Several epidemiologic studies have shown a possible association between thyroid function and cognitive decline. Our aim was to evaluate the association of subclinical hyperthyroidism and dementia in a population sample of older people. Methods: A cross-sectional study - São Paulo Ageing & Health Study (SPAH) - in a population sample of low-income elderly people ≥ 65 years-old to evaluate presence of subclinical thyroid disease as a risk factor for dementia. Thyroid function was assessed using thyrotropic hormone and free-thyroxine as well as routine use of thyroid hormones or antithyroid medications. Cases of dementia were assessed using a harmonized one-phase …

Research Note: Exploration Of Factors That Impede Door-To-Balloon Times, Erin Troby

Inquiry: The University of Arkansas Undergraduate Research Journal

When experiencing an acute myocardial infarction (AMI), more commonly known as a heart attack, patients need rapid treatment in order to open up and reestablish blood flow within the coronary artery. By far, the most common way to do this is an invasive procedure that allows a physician to inflate a tiny balloon into the plaque-filled area of the artery. The American College of Cardiology (ACC) and the American Heart Association (AHA) have established a 90-minute goal for this procedure, which means that, from the time a patient enters the door of the emergency department (ED), the medical team has …

Hydatid Cyst Disease Of The Thorax, Saulat H. Fatimi, Naima Waqar Butt, Taimur Saleem, Mohammad Asim Beg

Section of Cardiothoracic Surgery

Hydatid disease is a frequently encountered entity in endemic areas and constitutes a serious health problem. The lung is the second most commonly affected organ after the liver. In three of four cases of pulmonary hydatid cyst, the cyst is solitary. The early phase after primary infection is always asymptomatic. Primary symptoms in patients with pulmonary cystic echinococcosis include cough, fever, and chest pain. The clinical and radiological manifestations for the hydatid cyst in the lung depend on the integrity of the cyst. Bronchial fistulization is an important event in the evolution of the cyst. In cases of dubious orientation …

Clinico-Morphological Correlations In The Categorization Of Holes Between The Ventricles., Brad A. Friedman, Anthony Hlavacek, Karen Chessa, Girish S. Shirali, Eowyn Corcrain, Diane Spicer, Robert H. Anderson, Sinai Zyblewski

Manuscripts, Articles, Book Chapters and Other Papers

Controversy still exists in the categorization of holes between the ventricles, although they are the most common congenital cardiac malformation. Advanced imaging techniques such as three-dimensional echocardiography and computed tomographic angiography offer superb anatomical details of these defects. In this review, we have sought to collate the features highlighted in different categorizations and identify their similarities, but also emphasize their differences. We hope that an analysis of this type, now achievable during life, using advanced imaging, might lead to the appearance of a unified system for diagnosis and description of holes between the ventricles.
