Cardiac electrophysiology is an evolving specialty that has seen rapid advances in recent years. Concurrently, there has been much progress in the field of cardiac imaging. Electrophysiologists are increasingly requesting cross-sectional imaging in advance of many procedures. Pulmonary vein isolation and left atrial appendage (LAA) occlusion are now an established treatment options for atrial fibrillation. In patients undergoing pulmonary vein isolation, applications of computed tomography (CT) include evaluating the left atrial and pulmonary venous anatomy, excluding LAA thrombus and assessing for pulmonary vein stenosis...

OBJECTIVE: Pulmonary hypertension (PH) is associated with bronchopulmonary dysplasia (BPD). Screening strategies, a thorough investigation of co-morbidities, and multidisciplinary involvement prior to anti-PH medications have been advocated by recent guidelines. We sought to evaluate current practices of neonatologists caring for premature infants with PH. DESIGN: Electronic survey of American Academy of Pediatrics neonatology members. RESULTS: Among 306 neonatologist respondents, 38% had an institutional screening protocol for patients with BPD; 83% screened at 36 weeks for premature neonates on oxygen/mechanical ventilation...

BACKGROUND: Annulus-sparing (AS) repair of tetralogy of Fallot (TOF) carries a potential increased risk reoperation for re-stenosis and unproven benefits on right ventricular (RV) geometry. METHODS: Primary TOF repairs (N=434) between 2000 and 2012 were studied using risk-adjusted parametric techniques. Progression of cardiac dimensions were analyzed using repeated measures regression using reports of all 2,103 echocardiograms undertaken throughout the study period, to maximum follow-up 13...

In this study, we report a patient with pulmonary atresia with intact ventricular septum (PA/IVS), confluent pulmonary arteries supplied by an arterial duct, and chromosome 22q11.2 microdeletion. The 22q11.2 deletion syndrome has been associated with anomalies of the outflow tracts, such as tetralogy of Fallot with either pulmonary stenosis or atresia, but we are aware of a solitary case described with pulmonary atresia when the ventricular septum is intact. The presence of genetic malformations can have long-term co-morbidities...

Asthma is a heterogeneous disease, usually characterized by chronic airway inflammation. Various clinical conditions can mimic asthma, such as foreign body aspiration, subglottic stenosis, congestive heart failure, diffuse panbronchiolitis, aortic arch anomalies, reactive airway dysfunction syndrome, chronic obstructive pulmonary disease, retrosternal goiter, vocal cord tumors, other airway tumors, and vocal cord dysfunction. Upper airway obstruction can be a life-threatening emergency. Here, we present the case of a 58-year-old female with recurrent hospital visits for wheezing and exacerbations of asthma, who was later found to have a vocal cord nodule confirmed to be squamous cell carcinoma, which was mimicking like asthma...

Williams syndrome is a rare neurodevelopmental disorder characterized by mental retardation, growth deficiency, hypercalcemia, cardiac defects, and a distinctive facial appearance. Cardiovascular abnormalities are present in approximately 80% of Williams syndrome patients. Surgical treatment is generally performed for supravalvular aortic stenosis, aortic coarctation, pulmonary artery stenosis, or ventricular septal defect. In rare cases, diffuse hypoplasia of the aortic arch with a normal left ventricular outflow tract and ascending aorta may be diagnosed in early childhood...

BACKGROUND: Left atrial (LA) dysfunction, expressed as impaired LA deformation using two-dimensional (2D) strain imaging, has been observed in association with rheumatic mitral stenosis (MS). However, the clinical role of speckle tracking echocardiography (STE)-derived LA strain has rarely been studied in MS. AIM: This study aimed to identify the determinants of New York Heart Association (NYHA) functional class in patients with mitral stenosis and to investigate the relationship between left atrial deformation as measured by two-dimensional STE-derived LA strain and heart failure symptoms...

OBJECTIVE: Palliation of hypoplastic left heart syndrome with a standard nonvalved right ventricle to pulmonary artery conduit results in an inefficient circulation in part due to diastolic regurgitation. A composite right ventricle pulmonary artery conduit with a homograft valve has a hypothetical advantage of reducing regurgitation, but may differ in the propensity for stenosis because of valve remodeling. METHODS: This retrospective cohort study included 130 patients with hypoplastic left heart syndrome who underwent a modified stage 1 procedure with a right ventricle to pulmonary artery conduit from 2002 to 2015...

OBJECTIVES: The significant morbidity of long-term pulmonary regurgitation (PR) has driven the development of pulmonary valve (PV) sparing repair strategies in patients with tetralogy of Fallot (ToF). We assessed mid-term PV function in patients who underwent primary ToF repair with valve-sparing intraoperative balloon dilation (IBD) technique. METHODS: We evaluated 162 consecutive patients with ToF and pulmonary stenosis (ToF-PS) who underwent valve-sparing repair with IBD under 1 year of age...

A case of tracheobronchial stenosis due to tuberculosis in a young woman is presented. Compromised pulmonary function due to near-total obstruction of the proximal left main bronchus was diagnosed. Treatment options included surgical resection, endobronchial dilation or stenting, and argon photocoagulation. An approach was chosen to address symptoms without aggressive resection or commitment to stenting. She remains monitored and, while possibly committed to future intervention, no bridges have been burned with respect to more definitive and invasive therapies...

Even though, the incidence of Mitral Stenosis (MS) has reduced grossly, it still remains a health problem in developing countries and is the most common rheumatic valvular lesion encountered in pregnant patients. The already compromised cardiac status of a pregnant female deteriorates further by the presence of MS. So, pregnancy is a common situation during which untreated and frequently poorly tolerated MS are first diagnosed. Percutaneous Balloon Mitral Valvuloplasty (BMV) may be life saving in such a setting and a multidisciplinary approach in the management reduces the mortality and morbidity during the procedure...
