Quadricuspid pulmonary valve: computed tomography case series and review of relevant literature.

Quadricuspid pulmonary valve (QPV) is a rare congenital cardiac entity. The recognition of QPV has clinical significance as it can cause pulmonary valve dysfunction. It is also important to recognize this condition in patients undergoing the Ross procedure.

Quadricuspid aortic valve with ruptured sinus of Valsalva.

We present a case of a 24-year-old woman who was diagnosed with quadricuspid aortic valve with ruptured sinus of Valsalva. Quadricuspid aortic valve is a rare congenital cardiac anomaly. The recognition of quadricuspid aortic valve has clinical significance as it causes aortic valve dysfunction, and is often associated with other congenital cardiac abnormalities.

Measurement of left and right ventricular volumes with tomographic equilibrium radionuclide angiocardiography and cardiac MRI.

Objective: We previously developed an operator-interactive method for the measurement of left ventricular (LV) and right ventricular (RV) ejection fraction (EF) and end-systolic volume (ESV) and end-diastolic volume (EDV) using single-photon emission tomographic equilibrium radionuclide angiocardiography (SPECT ERNA). We aimed to compare our SPECT ERNA method with cardiac MRI (CMRI) for the determination of ventricular measures.

Methods: Paired measurements of LV and RV EFs and ESV and EDV were carried out by SPECT ERNA and CMRI in a group of patients who had myocardial infarction due to left anterior descending coronary artery thrombosis.

Quadricuspid aortic valve by cardiac magnetic resonance imaging: a case report and review of the literature.

Quadricuspid aortic valve (QAV) is a rare congenital cardiac entity. The recognition of QAV has clinical significance as it causes aortic valve dysfunction, commonly aortic regurgitation, and is often associated with other congenital cardiac abnormalities. We showed the important role played by cardiac magnetic resonance imaging in detecting QAV and review the available literature to explain its incidence, diagnosis, classifications, embryology, correlation between morphology of the QAV and its function, associated conditions, and management.
