Four cases are presented to illustrate the echo patterns of pulmonary valve motion in patients with pulmonary regurgitation caused by pulmonary hypertension, idiopathic dilatation of the pulmonary artery, or congenital absence of the pulmonary valve or in association with pulmonary stenosis. Absence of the pulmonary 'a' wave, fluttering of the e-f slope, and midsystolic closure or 'notching' of...

transluminal balloon valvuloplasty is an alternative to surgical valvotomy for congenital pulmonary valve stenosis. the aim of this study was to evaluate the long term results (to 13.5 years) of balloon pulmonary valvuloplasty. from june 1998 to january 2012, percutaneous balloon pulmonary valvuloplasty for congenital pulmonary valve stenosis was performed in 98 patients (50 males, 48 females, ...

Introduction: It is well-documented that right-sided heart dysfunction and significant tricuspid valve regurgitation (TVR) have adverse effects on patient outcomes after left-sided heart valve surgery. Therefore, the evaluation of right ventriclular (RV) function and TR severity in patients who had undergone mitral valve replacement (MVR), associated with/without concomitant su...

BACKGROUND At present, the exclusion for percutaneous pulmonary valve implantation for free pulmonary regurgitation after tetralogy of Fallot repair includes an unfavourably large right ventricular outflow tract. OBJECTIVE To report feasibility and early experience with a recently developed transcatheter heart valve, Venus P-valveTM, implanted in six patients with severe pulmonary regurgitati...

Despite recent renewed interest in the detection of tricuspid valve regurgitation by echocardiographic and Doppler techniques, little morphologic information is available on dysfunctioning tricuspid valves. This report describes 45 necropsy patients with clinical and morphologic evidence of pure (no element of stenosis) tricuspid regurgitation and provides morphometric observations (anular circ...

OBJECTIVE To evaluate the results of pulmonary valve replacement in patients with severe pulmonary regurgitation after tetralogy of Fallot repair in Hong Kong. DESIGN Retrospective review. SETTING University teaching hospital, Hong Kong. PATIENTS Consecutive patients undergoing pulmonary valve replacement after repair of tetralogy of Fallot between August 2002 and December 2008. MAIN OU...

Tetralogy of Fallot is the most common form of cyanotic congenital heart disease, with a prevalence of 0.26–0.8 per 1000 live births. Total repair for tetralogy of Fallot has been available for 50 years with a favourable outcome in most patients. Today, one is faced with an increasing number of patients with residual pulmonary regurgitation. It was previously thought that pulmonary regurgitatio...

Pulsed Doppler echocardiography in healthy individuals often shows a disturbance of diastolic flow in the right ventricular outflow tract just below the pulmonary valve that suggests regurgitation. This disturbance of diastolic flow was studied in 50 healthy individuals and 40 patients with cardiopulmonary disease, some of whom had a pulmonary regurgitant murmur. Diastolic flow was disturbed in...

We present a 73 years old woman who presented with pelvic cancer, ongoing sepsis and presumably a new diastolic murmur. Her transthoracic echocardiogram, as part of a sepsis screen, showed an abnormal pulmonary valve with moderate regurgitation. Trans-oesophageal echocardiography using 3D imaging showed a bicuspid pulmonary valve as the cause for the moderate regurgitation, but with no clear so...

Pulsed Doppler echocardiography was used to determine prospectively the prevalence of mitral, aortic, tricuspid and pulmonary regurgitation in 80 consecutive patients with mitral valve prolapse and 85 normal subjects with similar age and sex distribution. Mitral valve prolapse was defined by posterior systolic displacement of the mitral valve on M-mode echocardiography of 3 mm or more (40 patie...
