One year after surgical repair of the truncus arteriosus, a 1-year 8-month-old boy was found to have a pseudoaneurysm of the right ventricular outflow tract (RVOT). Cine-magnetic resonance imaging (MRI) showed a narrow communication between the RVOT and aneurysm. MRI was useful to evaluate the anatomical and spatial relations between the pseudoaneurysm and the surrounding structures, therefore ...

The right ventricle outflow tract (RVOT) is the most common site of origin of idiopathic ventricular arrhythmias. The typical outflow tract arrhythmias pattern on ECG is an inferior axis deviation and left bundle branch block when originated on the RVOT and right bundle branch block morphology when originated on the left ventricular outflow tract (LVOT). There are several ECG tricks for differe...

Right ventricular outflow tract (RVOT) ventricular tachycardias (VT) occur in the absence of structural heart disease and are called idiopathic ventricular arrhythmias. These arrhythmias are thought to be produced by adenosine-sensitive, cyclic AMP mediated, triggered activity and are commonly observed in adolescents and young adults. In the ECG, they appear with a wide QRS complex, a left bund...

Background. Despite current trends toward early primary repair, the surgical systemic-to-pulmonary shunt is still considered first-choice palliation in patients with critical tetralogy of Fallot (TOF) and duct-dependent pulmonary circulation unsuitable for repair. However, stenting right ventricular outflow tract (RVOT) nowadays emerging as an effective alternative to selected patients. Methods...

Objective: To detect residual RV dysfunction on a right ventricle focused Transthoracic Echocardiography (TTE) in COVID-19 infection survivors with lung involvement.
 Study Design: Analytical Cross sectional study design.
 Place and Duration of Study: Combined Military Hospital Abbottabad Pakistan, Feb 2022 to Apr 2022.
 Methodology: 87 patients who had suffered from survived def...

A 50-year-old man with idiopathic premature ventricular contractions (PVCs; PVC 1, Figure 1A) and ventricular tachycardias (VTs) was referred for catheter ablation. Activation and pace mapping were performed at multiple sites in the right and left ventricular outflow tracts (RVOT and LVOT) (Figure 1). Nonirrigated radiofrequency (RF) applications delivered in the left coronary cusp where pacing...

BACKGROUND The optimal surgical treatment of patients with transposition of the great arteries, ventricular septal defect, and pulmonary stenosis is controversial. Although the Rastelli operation has been standard surgical management of this lesion, aortic root translocation with right ventricular outflow tract (RVOT) reconstruction (Nikaidoh) and the pulmonary artery translocation (Lecompte) o...

BACKGROUND Premature ventricular beats (PVBs) and monomorphic ventricular tachycardia originating from the right ventricular outflow tract (RVOT) are the most frequent forms of idiopathic ventricular arrhythmias, but arrhythmia originating from the left ventricular outflow tract (LVOT) may be found in about 10% of these patients. AIM To compare electrocardiographic (ECG) patterns and duration...

OBJECTIVES This study sought to determine the diagnostic accuracy and impact of the systematic use of coronary echocardiography in a large group of preoperative patients with tetralogy of Fallot (TOF). BACKGROUND Accurate preoperative identification of an anomalous coronary artery crossing the right ventricular outflow tract (RVOT) in patients with TOF is important to prevent coronary injury ...
