giant left atria are defined as those measuring larger than 8 cm and are typically found in patients who have rheumatic mitral valve disease with severe regurgitation. enlargement of the left atrium may create compression of the surrounding structures such as the esophagus, pulmonary veins, respiratory tract, lung, inferior vena cava, recurrent laryngeal nerve, and thoracic vertebrae and lead t...

Diffuse alveolar hemorrhage (DAH) can be caused by several etiologies including vasculitis, drug exposure, anticoagulants, infections, mitral valve stenosis, and regurgitation. Chronic mitral valve regurgitation (MR) has been well documented as an etiological factor for DAH, but there have been only a few cases which have reported acute mitral valve regurgitation as an etiology of DAH. Acute mi...

Thirty-five children with pulmonary stenosis were catheterized from 1 day to 9 years of age and recatheterized after 2 weeks to 15 years. Right ventricular systolic pressure rose in 24 and the increase was greater in those under than over 5 years old. Pulmonary valve orifice area per square metre of body surface area increased in 12, but did not change in 3, and fell in 17; absolute decrease in...

INTRODUCTION Stress cardiomyopathy is a condition of chest pain, breathlessness, abnormal heart rhythms and sometimes congestive heart failure or shock precipitated by intense mental or physical stress. CASE PRESENTATION A 64-year-old male with a known diagnosis of moderate-to-severe aortic stenosis and advised that valve replacement was not urgent, presented with acute pulmonary edema follow...

A six-year-old boy presented to the Cardiology clinic with history of mild cyanosis and dyspnea on exertion from age 1. He had a to-and-fro murmur at the middle left sternal border. Chest examination was normal but chest x-ray showed a small left lung. Echocardiography established the diagnosis of tetralogy of Fallot (TOF) and absent pulmonary valve with severe pulmonary regurgitation and moder...

BACKGROUND Low-gradient severe aortic stenosis with preserved ejection fraction is an increasingly recognized entity, and symptomatic patients may benefit from aortic valve replacement. However, systemic hypertension frequently coexists with low-gradient severe aortic stenosis, which itself may cause elevated left ventricular (LV) filling pressures with resultant symptoms of dyspnea. METHODS ...

Twenty nine patients (19 male, mean (SD) age 6.25 (0.5) years (range 0.16-15 years] with typical pulmonary valve stenosis were treated by balloon dilatation of the pulmonary valve. They were studied by echocardiography before the procedure, immediately after it, and at follow up (mean (SD) 10.2 (5.6) months, n = 18). The morphology of the pulmonary valve, the right ventricular-pulmonary artery ...

initiated pediatric cardiac interventions. Interventional Pediatric Cardiology since then has come a long way and several lesions are now primarily treated by interventional catheterization. These include pulmonary valve stenosis, aortic stenosis, patent ductus arteriosus, aortic recoarctation. In other situations, interventions are used preferably over surgery including native coarctation of a...

Ten patients with valvular pulmonic stenosis were studied by simultaneous external phonocardiograms and intracardiac pressure recordings during successive respiratory cycles to examine the mechanism of the respiratory variation in the ejection click. Selective cineangiograms were perforned in four. During inspiration right ventricular end-diastolic pressure (RVEDP) exceeded the pressure in the ...
