Acute Gastroenteritis in Children Below 5 Years of Age at Tirupati, Andhra Pradesh, India Post Introduction of Rotavirus Vaccine into National Immunization Programme.

Objective: To identify the burden of rotavirus acute gastroenteritis (AGE) and the genotypes presenting in the authors' area in the period after introduction of rotavirus vaccine in Universal Immunization Programme (UIP).

Methods: Children aged less than 5 y and presenting to hospital for the treatment of AGE were enrolled into the study from January 2016 to June 2019. Clinical details including age, gender, extent of illness, number of stools, concomitant vomiting and fever, grade of dehydration, and associated illness were recorded.

Correlation of coronary artery calcium score and carotid artery intima-media thickness with severity of coronary artery disease.

Coronary artery calcium score (CACS) and carotid artery intima-media thickness (CIMT) are the markers of atherosclerosis. An association between CACS and CIMT with presence of atherosclerotic coronary artery disease (CAD) is well established. However relationship between severity of CAD with CACS and CIMT is less clear.

Novel single nucleotide mutations in exon-10 of human coagulation Factor V gene in patients with pulmonary thromboembolism.

Acute pulmonary thromboembolism (PTE) presents with wide spectrum and has variable prognosis. Factor V Leiden (FVL) is the most common inherited thrombophilia, with a prevalence of 3%-7% in the general US population, approximately 5% in Whites, 2.2% in Hispanics and 1.

New integrated approach to percutaneous mitral valvuloplasty combining Wilkins score with commissural calcium score and commissural area ratio.

Background: Present echocardiographic scoring systems for percutaneous mitral valvuloplasty (PMV) have limitations, and no scoring system is significant determinant of procedural outcome. In this study, we assess the relationship between various echocardiographic parameters and scoring systems with immediate outcomes and test an integrated approach by combining Wilkins score with other parameters.

Methods: One hundred two patients who had undergone PMV were included in this prospective observational study.

Right Ventricle before and after Atrial Septal Defect Device Closure.

Background: Percutaneous atrial septal defect (ASD) device closure is a safe and effective means of reducing or eliminating interatrial shunting. The response of the right heart to device closure is incompletely understood.

Aim: To evaluate the effects of transcatheter closure of secundum ASD on right ventricle size and function, that is, both systolic and diastolic by transthoracic echocardiography (TTE) over a 6-month period.

Real Time 3D Echocardiographic Evaluation of Iatrogenic Atrial Septal Defects After Percutaneous Transvenous Mitral Commissurotomy.

Introduction: Percutaneous transvenous mitral commissurotomy (PTMC) is a safe and effective procedure for relief of severe mitral stenosis. PTMC is being done widely and many transseptal procedures requiring large diameter catheters, sheaths are becoming popular. The knowledge of iatrogenic atrial septal defect (iASD) is vital.

Predictive Value of D-Dimer Levels and Tissue Doppler Mitral Annular Systolic Velocity for Detection of Left Atrial Appendage Thrombus in Patients with Mitral Stenosis in Sinus Rhythm.

Background: Transesophageal echocardiogram (TEE) is a gold standard test for diagnosis of left atrial (LA) thrombus, but it has limited sensitivity for identification of small thrombi within side lobes. Thus, the absence of visualizing a left atrial appendage (LAA) thrombus does not equate with the absence of a LAA thrombus.

Aim: To assess the predictive value of mitral annular systolic velocity (Sa) and D-dimer for the detection of LA thrombus and spontaneous echocardiographic contrast (SEC) in mitral stenosis (MS) patients with sinus rhythm (SR).
