BACKGROUND Percutaneous pulmonary valvuloplasty is well established treatment of choice in pulmonary valve stenosis. AIM The aim of our study was to present our experience with the interventional technique, its immediate and mid-term effectiveness as well as its complication rate. MATERIAL AND METHODS The study included 43 patients, where 33 (74%) of them were children between the age of 1 ...

Systolic anterior motion (SAM) of mitral valve is the prolapse of a mitral leaflet into the left ventricle outflow tract (LVOT) during systole, causing LVOT obstruction and mitral valve regurgitation. We report the case of a patient who developed SAM-induced hemodynamic instability during bleeding with a clinical picture resembling pulmonary edema. A 77-year-old woman was admitted to our emerge...

Background After surgical correction of Tetralogy of Fallot (TOF), residual pulmonary regurgitation (PR), right ventricular (RV) dilatation and RV failure have been associated with adverse clinical events and are considered criteria for pulmonary valve replacement. Cardiovascular magnetic resonance imaging (CMR) is the gold-standard for evaluation of these parameters. However it is an expensive...

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital coronary artery defect leading to sudden cardiac death. Diagnosis is made after the onset of symptoms, mainly in the pediatric population. We describe an uncommon presentation of ALCAPA and rheumatic mitral valve regurgitation, diagnosed by a coronary 64-CT scan performed before a planned mitral...

Percutaneous Pulmonary Valve Implantation— Clinical Context For many congenital heart defects treated in infancy (eg, tetralogy of Fallot, transposition of the great arteries, double outlet right ventricle), long-term right ventricular outflow tract (RVOT) dysfunction, in the form of pulmonary stenosis and regurgitation, is a common finding as patients become older (older children, adolescents,...

BACKGROUND Pulmonary regurgitation can lead to severe right ventricular dysfunction, which is a delicate postoperative problem in the long-term follow-up of patients who had surgery for congenital heart diseases. Clinical conditions of patients suffering from pulmonary valve incompetence are improved by valve replacement with a prosthetic valve. To date, the surgical approach is the only option...

Primary mitral regurgitation is generally an insidious disease with late onset of symptoms. Current European and American guidelines recommend surgery in severe primary mitral regurgitation when symptoms, overt left ventricular dysfunction, pulmonary hypertension or atrial fibrillation, occur. However, recent large studies reported an improved outcome in asymptomatic patients with severe mitral...

A2-year-old cachectic cross-breed gelding was admitted toVeterinary Teaching Hospital of University of Tehran followingthe onset of a marked respiratory distress, coughing and ventraledema. Clinical examinations indicated harsh respiratory andexpiratory sounds as well as jugular vein distention. Therespiratory and heart rates were 35/min and 60 bpm, respectively.Agrade III/IV pansystolic murmur...

left ventricular outflow tract obstruction. In patients with predominant aortic regurgitation, especially those with bicuspid aortic valve or rheumatic fever associated with a geometric mismatch between the aortic and pulmonary valve due to dilated aortic annulus, the Ross procedure should be employed more selectively, and technical modifications that aim to prevent future annular and root dila...

T he prevalence of valve regurgitation in healthy people has been previously examined by echocardiography. Pulmonary regurgitation or tricuspid regurgitation (TR) was common, mitral regurgitation (MR) was less common, and aortic regurgitation was generally undetectable. In addition, the prevalence of regurgitant signals varies with age or sex. Assuming that a low prevalence of regurgitant signa...
