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

Reversible obstruction of the ventricular outflow tract

The American Journal of Cardiology, 1963
Abstract Obstruction of the left ventricular outflow tract with characteristics of subaortic muscular hypertrophy has been produced in a human subject and 2 of 8 dogs by infusion of isoproterenol. In 2 other dogs with outflow tract gradients in the “control” state, infusion of blood relieved the obstruction.

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.

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 ...

Left Ventricular Outflow Obstruction in Infancy and Childhood

Archives of Surgery, 1969
Left ventricular outflow obstruction occurs in 3% to 5% of cardiac anomalies encountered in the pediatric age group. The obstructing lesion may be supravalvular, valvular, subvalvular, or a combination of more than one lesion. 1,2 The indication for surgical intervention in these patients is not yet fully defined.

Left Ventricular Volume and Hypertrophy in Outflow Obstruction

Cardiovascular Research, 1968
Left ventricular wall thickness and ejection fraction were found to be increased in 17 patients with either hypertrophic obstructive cardiomyopathy or organic obstruction to left heart outflow. Concentric hypertrophy appears to take place partly by inward growth, and this behaviour may be important for understanding the diseases associated with it.

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.

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 ...
