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.

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

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 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.

Right Ventricular Myxoma Obstructing the Outflow Tract

The American Heart Hospital Journal, 2010
Cardiac myxomas are benign tumors of endocardial origin. Symptoms might mimic heart disease as well as infectious disease, immunodeficiency, and malignant processes. We present the case of a 59-year-old female patient with a large right ventricular myxoma that was connected to the basal interventricular septum.

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 ...

Apicoaortic Shunts for Left Ventricular Outflow Obstruction

The Annals of Thoracic Surgery, 1986
Extracardiac conduits were envisioned in 1910 (Carrel) and used clinically in the mid-l950s, yet little long-term postoperative follow-up data currently exist. In this issue of The Annals (p 609), Sweeney and associates discuss 38 patients with apicoaortic shunts created between 1975 and 19M, and analyze the follow-up results.

Update on Left Ventricular Outflow Tract Obstruction

Journal of Cardiovascular Imaging
Abstract The diagnosis and management of left ventricular outflow tract obstruction have evolved substantially since its initial characterization by invasive cardiac catheterization nearly 70 years ago. This review traces the historical progression of our understanding of left ventricular outflow tract obstruction, with a particular focus on ...

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.
