Lead I R‐wave amplitude to differentiate idiopathic ventricular arrhythmias with left bundle branch block right inferior axis originating from the left versus right ventricular outflow tract

Cardiovascular Electrophysiology, 2018
Differentiation of right versus left ventricular outflow tract (RVOT vs. LVOT) arrhythmia origin with left bundle branch block right inferior axis (LBRI) morphology is relevant to ablation planning and risk discussion.

Hemangioma of the right ventricular outflow tract

The Annals of Thoracic Surgery, 2000
Obstruction of the right ventricular outflow tract by a primary cardiac tumor is rare. Six cases of right ventricular outflow tract obstruction by a primary cardiac hemangioma have been reported; all but one were detected before the age of 25 years. In this report, we review the literature and describe what we believe to be only the second reported ...

Right ventricular outflow tract pseudoaneurysm: Two cases

Journal of Cardiovascular Computed Tomography, 2011
Right ventricular pseudoaneurysm is a rare complication following repair of Tetralogy of Fallot. Presented are two patients, both with history of Tetralogy of Fallot, successful repair and pseudoaneurysms discovered on symptomatic follow up. Because surgical intervention is often required, the location and characteristics of the pseudoaneurysm are ...

Monocusp Valve in Right Ventricular Outflow Tract

Scandinavian Cardiovascular Journal, 1999
Sixty patients aged 5 days-10.3 years (mean 2.9 years) received monocusp valve implants in the right ventricular outflow tract in corrective surgery for congenital heart disease. The free edge of the monocusp valve was attached to the posterior wall of the new pulmonary tract to cover the entire root of the pulmonary tract when the monocusp valve ...

Reoperative homograft right ventricular outflow tract reconstruction

The Annals of Thoracic Surgery, 2001
Homografts are implanted in the right ventricular outflow tract (RVOT) of children, with the knowledge that reoperation might be required. We reviewed 14 years of homograft RVOT reconstruction to assess the feasibility of homograft replacement and to determine risk factors for homograft survival.From February 1985 through March 1999, 223 children (age ...

Right Ventricular Outflow Tract Lesions

2007
Valvar pulmonary stenosis can present as isolated congenital anomaly or as part of other complex congenital heart abnormalities, such as tetralogy of Fallot, transposition of great arteries, or syndromes such as Noonan syndrome.

Exercise provocable right ventricular outflow tract tachycardia

American Heart Journal, 1982
During the past 5 years, we have seen six patients who met inclusion criteria of exertional palpitations, reproducible treadmill (TM) provocable ventricular tachycardia (VT), and performance of electrophysiologic (EP) studies including isoproterenol (ISO) infusion. There were five males and one female, aged 15 to 55 years (mean +/- SD, 31 +/- 18 years).

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.

Edrophonium‐Induced Right Ventricular Outflow Tract Tachycardia

Pacing and Clinical Electrophysiology, 2005
Idiopathic right ventricular outflow tract‐ventricular tachycardia (RVOT‐VT) generally occurs when sympathetic nervous system activity is increased, though, in a few patients, it develops when parasympathetic nervous activity (PNA) is increased. Among 101 consecutive patients with RVOT‐VT confirmed by endocardial catheter mapping, 5 (4.9%) presented ...
