OBJECTIVES: This study sought to investigate whether left atrial (LA) functional measures predict atrial fibrillation (AF) in the general population. BACKGROUND: Increasing evidence suggests LA functional measures are predictors of AF in several patient groups. METHODS: In a community-based cohort study, approximately 2,000 individuals underwent a transthoracic echocardiogram. Conventional echocardiographic measures and extended LA measures, including the minimal and maximal LA volumes (LAVmin and LAVmax , respectively) and left atrial emptying fraction (LAEF), were performed...

Background: Cardiopulmonary disease is a major cause of morbidity and mortality in persons with sickle cell disease (SCD). Tricuspid regurgitant jet velocity (TRJV) and predicted forced expiratory volume in 1 s (FEV1%) predicted are independently associated with death in SCD. The goal of this study was to determine the prevalence of elevated TRJV and the association, if any, between TRJV and FEV1% predicted among persons with sickle cell anaemia (SCA) in Nigeria. Methods: Using a cross-sectional design, we enrolled 100 adult Nigerians (≥15 y) with SCA...

About 20-30% of people infected with Chagas disease present with chronic Chagas cardiomyopathy (CCC), the most serious and frequent manifestation of the disease, while others remain asymptomatic and often do not experience Chagas-specific mortality. It is not currently well understood what causes these differential disease outcomes, but a genetic predisposition within the host could play an important role. This study examined variants in the NLRP1, CARD, and CASP1 inflammasome genes among 62 T. cruzi seropositive patients from Bolivia (38 cases with CCC and 24 asymptomatic controls) to uncover associations with CCC...

BACKGROUND: Left axis deviation (LAD) discovered in children via electrocardiogram (ECG) is uncommon but can be associated with heart disease (HD). The optimal diagnostic approach in a seemingly healthy child with LAD is unclear. We sought to better stratify which patients with LAD but without previously known HD may warrant additional workup. METHODS: A retrospective chart review was performed to identify patients ≥1 to <18 years of age with LAD (QRS frontal plane axis 0 to -90) on an ECG between January 2002 and December 2014...

PURPOSE: Catheter-directed thrombolysis (CDT) is a relatively new therapy for pulmonary embolism that achieves the superior clot resolution compared to systemic thrombolysis while avoiding the high bleeding risk intrinsically associated with that therapy. In order to examine the efficacy and safety of CDT, we conducted a retrospective cohort study of patients undergoing ultrasound-assisted CDT at our institution. METHODS: The charts of 30 consecutive patients who underwent CDT as a treatment of pulmonary embolism at our institution were reviewed...

Abnormal noninvasive stress test (NIST) findings do not always correlate with angiographically significant (luminal obstruction ≥50%) coronary artery disease. Positive predictive value (PPV) of NIST in the real clinical practice is not well known. The goal of this retrospective study was to determine the PPV of NIST and assess the factors affecting PPV in a US community hospital. This study included all consecutive patients (n = 355) who underwent invasive coronary angiography after a positive NIST within ~1-year duration at our institution...

Current screening guidelines are available for anthracycline-induced cardiotoxicity. However, the utility of echocardiogram screening for late-onset anthracycline cardiotoxicity especially in the decade immediately after end of therapy is debatable. A retrospective chart review of patients seen in the Thriving after Cancer Clinic at Rady Children's Hospital January 2006 to December 2013 was performed. Treatment data, echocardiogram results, cardiology referral notes and cardiac medication data were abstracted from anthracycline-exposed survivors...

Aortic arch anomalies refer to congenital malformations of position or branching pattern of the aortic arch. To-date, only a few small studies have documented prenatal detection of aortic arch anomalies. In this article, we share our experience in detecting aortic arch anomalies. Foetal echocardiograms, clinic and genetic histories of 33 patients who had been diagnosed with aortic arch anomaly from 2007 to 2015 were reviewed. In 15 patients, right aortic arch with mirror image branching; in 13 patients, right aortic arch with left ductus arteriosus and aberrant left subclavian artery; in three patients, left aortic arch with aberrant right subclavian artery; in one patient bilateral ductus and right aortic arch with aberrant left subclavian artery and in one patient double aortic arch were detected...
