Penetrating cardiac injuries are commonly instantaneously lethal. However, numerous delayed manifestations of cardiac injury, including traumatic ventricular septal defect, ventricular aneurysms, right pulmonary artery to left atrial fistula, valvular regurgitation, and aorto-right ventricular fistula, are all described in the literature. Here, we present a case of aorto-right ventricular fistu...

A case of a 51-year old male is presented. A left bundle branch block inferior axis tachycardia was manifest. At electrophysiological study this tachycardia was inducible and was ablated in the septal right ventricular outflow tract (RVOT). Two other tachycardias were identified both with right bundle branch block (RBBB) morphology raising the suspicion of diffuse pathology. Arrythmogenic right...

Magnetic resonance imaging (MRI) is particularly valuable in the assessment of diseases that affect the right heart. Concomitant physiological provocation may unmask latent pathology and provide incremental information to inform prognosis and guide therapy. For example, lowdose dobutamine stress MRI has been shown to unmask right ventricular dysfunction in patients with repaired tetralogy of Fa...

Patients with pulmonary embolism (PE) present with a wide spectrum of clinical acuity that necessitates different therapeutic strategies. Most patients maintain normal systolic arterial pressure and normal right ventricular function. With therapeutic levels of anticoagulation, they will likely have a benign clinical course. Unfortunately, some PE patients suffer rapid clinical deterioration wit...

Background Cardiac magnetic resonance imaging (CMR) is the goldstandard technique for the assessment of right ventricular function. Recent data indicate that right ventricular ejection fraction (RVEF) <45% by CMR is a strong predictor of outcome in patients with dilated cardiomyopathy. However, the prognostic significance of RVEF in heart failure with preserved ejection fraction (HFpEF) is unkn...

background: we sought to assess right ventricular (rv) systolic and diastolic functions via tissue doppler imaging (tdi) in order to discriminate right-to-left (bidirectional) from left-to-right intracardiac shunts. methods: a tissue doppler velocity study via doppler echocardiography was performed in 20 patients with left-to-right shunt (without evidence of significant pulmonary hypertension) ...

conclusions in light of our findings, we concluded that ra function is severely diminished in adult patients with tof. it would play an important role in pathophysiological process of the right sided heart failure in these patients. results the myocardial velocities and deformational indices of ra free wall were significantly compromised in tof patients compared with normal subjects. there was ...

Thallium-201 myocardial scintigraphy was performed in patients with congenital heart defects to determine whether, by quantification of right ventricular isotope uptake, one could assess the degree of right ventricular hypertrophy and so predict the level of right ventricular pressure. A total of 24 patients ranging in age from 7 months to 30 years was studied; 18 were studied before corrective...
