Membranous right ventricular outflow obstruction

The American Journal of Cardiology, 1973
A case is reported of right ventricular outflow obstruction caused by a fibrous sac floating in the right ventricular cavity, attached to the tricuspid valve and to the rim of a targe ventricular septal defect. An anomalous membranous leaflet located under the pulmonary valve contributed to the obstruction. The clinical findings were those of tetralogy

An interventional approach to left ventricular assist device outflow graft obstruction

Catheterization and cardiovascular interventions, 2021
LVADs provide life‐sustaining treatment for patients with heart failure, but their complexity allows for complications. One complication, LVAD outflow graft obstruction, may be misdiagnosed as intraluminal thrombus, when more often it is extraluminal ...

Left ventricular outflow tract obstruction

Seminars in Thoracic and Cardiovascular Surgery: Pediatric Cardiac Surgery Annual, 2004
Left ventricular outflow tract obstruction can occur at the supravalvar, valvar, or subvalvar level. Each level of obstruction is associated with distinct symptomatology, natural history, and operative approach. Reconstructive techniques can usually be used with low operative risk and excellent immediate and longer-term outcomes.

Left Ventricular Outflow Tract Obstruction

NeoReviews, 2006
A term female newborn presents with a prenatal diagnosis of cardiac masses on prenatal echocardiography. ### Prenatal History: ### Birth History and Presentation: The baby was delivered by elective cesarean section after rupture of membranes with clear fluid. Apgar scores were 9 at both 1 and 5 minutes.

LEFT VENTRICULAR OUTFLOW OBSTRUCTION

Pediatric Clinics of North America, 1999
Patients with LVOT obstruction require lifelong follow-up because the obstruction may be progressive or recurrent. Several procedures are usually required, either by surgery or by interventional cardiac catheterization, to repair or palliate the obstructive lesion.

Transesophageal Echocardiographic Predictor of Significant Right Ventricular Outflow Tract Obstruction after Tetralogy of Fallot Repair.

Seminars in Thoracic and Cardiovascular Surgery, 2020
The optimal method for reconstruction of the right ventricular outflow tract in tetralogy of Fallot repair is yet to be established. Transatrial repair with pulmonary valve preservation avoids the detrimental effects of ventriculotomy and transannular ...

Mechanisms, pathophysiology, and diagnostic imaging of left ventricular outflow tract obstruction following mitral valve surgery and transcatheter mitral valve replacement

Echocardiography, 2019
Left ventricular outflow tract obstruction is a serious complication of mitral valve surgery (repair and replacement) and transcatheter mitral valve replacement.

Obstructions to left ventricular outflow

World Journal of Surgery, 1985
AbstractModern techniques of cardiopulmonary bypass combined with methods for myocardial protection make the conventional operations of prosthetic patch aortoplasty, aortic valvotomy, and transvalvular resection of subaortic membranes dependable and accurate procedures which can provide the obliteration or successful reduction of systolic gradients ...

Right ventricular outflow tract obstruction

2013
Congenital pulmonary valve abnormalities encompass a spectrum of anomalies that result in right ventricular outflow tract (RVOT) obstruction. Based on the level of obstruction, there are three possible variants: (a) valvular, (b) subvalvular (infundibular stenosis), and (c) supravalvular.

Recognition of Left Ventricular Outflow Obstruction

Circulation, 1965
The purpose of this report is to summarize the syndromes of obstruction to left ventricular outflow. Emphasis is placed upon the correlations between clinical, hemodynamic, and angiographic features that permit an accurate diagnosis. An exact definition of the problem in each patient has become of great importance because of rapid advances in cardiac ...
