Our aim was to analyze any changes during diastole in patients with normal left ventricular ejection fraction (LVEF), after pacemaker stimulation from the right ventricular outflow tract (RVOT) and right ventricular apex (RVA) lead position. This was a prospective, randomized, follow up study, which lasted for 12 months. Our research included 132 consecutive patients who were implanted with a p...

Fig. 1. (A) Non-contrast computed tomography showing the filter migrated into the r (arrowhead) in the RVand the right ventricular outflow tract (RVOT). We were not abl a big thrombus (arrow). (C) Intraoperating picture; a thrombus in the RV and the filte the filter removed from the RV and RVOT. This is an extremely rare type of an inferior can be successful in many cases and there is no report...

Background In patients with congenital heart defects, restoration of the right ventricle outflow tract (RVOT) continuity by surgical or percutaneous bovine valve implantation is a common procedure. Flow characteristics in such valves are complex, therefore the aim of this study was demonstrating the potential application of 4D MRI flow for the comprehensive assessment of pulmonary flow patterns...

Primary tumors of the heart are rare, but they are often associated with refractory arrhythmias. Vascular tumors of the heart comprise a small minority of primary cardiac tumors. In patients with structurally normal hearts, ventricular tachycardia (VT) originating from the right ventricular outflow tract (RVOT) can be sensitive to adenosine, vagal maneuvers, and calcium channel blockers. In thi...

A case is presented, in which asymptomatic but persistent right ventricular outflow tract (RVOT) ectopics resulted in left ventricular (LV) dilatation and systolic dysfunction. The patient underwent extensive investigation with no other cause for the cardiomyopathy being found. Successful ablation of the RVOT ectopic focus resulted in normalization of LV size and function. This case suggests th...

Three-dimensional (3D) transthoracic echocardiography has advantages over traditional two-dimensional (2D) echocardiography in visualizing tricuspid valve morphology in Ebstein's anomaly. We describe the application of intra-operative 3D transesophageal echocardiography during a tricuspid valve repair procedure in a patient with Ebstein's anomaly. Intra-operatively three-dimensional transesopha...

OBJECTIVE The role of electrophysiology study in Brugada syndrome (BS) sudden cardiac death risk stratification remains controversial and seems to depend on the phenotypic expression of the channelopathy. Ajmaline has a key role in the diagnosis of BS. We observed that programmed electrical stimulation (PES) of the right ventricular outflow tract (RVOT), only when type 1 BS ECG is unmasked by a...

An electrophysiological study was performed in a 61 year old man with Wolff- Parkinson-White (WPW) syndrome. At baseline, neither ventricular nor supraventricular tachycardias could be induced. During isoprenaline infusion, ventricular tachycardia originating from the right ventricular outflow tract (RVOT) with a cycle length of 280 ms was induced and subsequently atrioventricular reentrant tac...

Surgical skill and strategy for the correction of tetralogy of Fallot (TOF) have improved and resulted in satisfactory outcomes. However, prematurity and low birth weight continue to remain risk factors for poor outcomes. We present a case of a 2,150 g neonate born with TOF, in whom palliation was achieved with right ventricular outflow tract (RVOT) stenting. Seventy-seven days after the proced...
