15 Possible Causes for Cardiac Catheterization showing Right to Left Shunt, Prominent A-Wave

  • Atrial Septal Defect

    In sinus venosus ASD, it shows left axis deviation and a negative P wave in lead III.[] Transesophageal echocardiography showed an increase of right to left shunt flow on sitting.[] Imaging The chest X-ray shows a dilated pulmonary artery, prominent pulmonary vascular markings, and enlarged right atrial and ventricular chambers in patients with significant[]

  • Eisenmenger Syndrome

    ECG of Eisenmenger syndrome Usually there is right ventricular hypertrophy with prominent P waves.[] Elevated jugular venous pressure and prominent "v" wave in right heart failure and severe tricuspid regurgitation.[] In tricuspid regurgitation, the jugular venous pressure may be elevated and shows a prominent "v" wave, Fig. ( 2 ).[]

  • Ostium Primum Atrial Septal Defect

    If MR is present, the findings of ASD may be modified Prominent v wave in JVP LV type apex IE may occur (unlike secundum ASD) ECG Incomplete RBBB pattern in v1 as in secundum[] The notched R waves in inferior leads are not so prominent. ECG 11.[]

  • Patent Foramen Ovale

    The clinical benefit of patent foramen ovale (PFO) closure in patients with cryptogenic stroke (CS) for recurrent stroke prevention has been a subject of extensive debate. Prior clinical trials failed to show superiority of PFO closure versus medical therapy. Meta-analyses suggested a possible benefit of PFO[…][]

  • Large Ventricular Septal Defect

    Abstract To evaluate the effects of acute afterload reduction, hydralazine, 0.2 mg/kg, was administered at cardiac catheterization to seven infants who had a large ventricular septal defect (VSD). The infants were 2.5 - 11 months old (mean 5.1 months). Before and 5, 15, 25 and 35 minutes after hydralazine, aortic,[…][]

  • Corrected Transposition of the Great Vessels

    ECG absence of Q waves in the lateral precordium (V4-6) physiologic Q waves in these leads often referred to as "septal" Q waves prominent Q waves in right precordium (V1-[]

  • Tetralogy of Fallot

    Additionally, right atrial enlargement is manifested by prominent P waves in V1 (*). Right ventricular hypertrophy is demonstrated by a rightward deviated axis.[] The electrocardiogram will demonstrate right axis deviation and prominent right ventricular forces, with large R waves in the anterior precordial leads and large S waves in[] A CXR (Chest X-Ray) of a child with tetralogy of Fallot Electrocardiogram: On EKG, patients with TOF will show increased right ventricular forces as evidenced by tall R waves[]

  • Ebstein Malformation

    The C wave is prominent because of a large mobile anterior tricuspid leaflet. 41.[] […] and v waves late in the course of the 36.[] […] negative sign. 39. • JVP – • The jugular pulse is normal except for a prominent C wave that coincides with mobility of the anterior tricuspid leaflet. • An attenuated X descent[]

  • Scimitar Syndrome

    Chest X-ray film showed Scimitar sign. Cardiac catheterization revealed 30% left to right shunt without atrial septal defect.[] Cardiac catheterization showed right-sided PAPVR, which drained as a common trunk into the RA at the inferior cavo-atrial junction.[] Pulmonary angiography showed anomalous pulmonary vein was drained to inferior vena cava and left atrium.[]

  • Persistent Truncus Arteriosus

    , right aortic arch and normal left ventricle (LV) function.[] Figure 1: Cardiac catheterization and angiography showing type 1 truncus arteriosus Click here to view Intraoperative TEE examination confirmed that the PA was arising posterior[] […] aorta with a truncal valve over riding interventricular septum (IVS) with moderate truncal valve regurgitation, large subtruncal VSD of 20 mm in size with bi-directional shunt[]
