Quadricuspid pulmonary valve complicated with aneurysm of pulmonary trunk diagnosed with ECG-gated computed tomography.
Quadricuspid pulmonary valve (QPV) is an uncommon congenital defect reported in the general population with a frequency of up to 0.25%. The defect usually does not cause severe clinical complications and its presence frequently remains clinically silent. Moreover, there are several difficulties in visualization of pulmonary valve using basic diagnostic modalities such as echocardiography. Therefore, in the majority of cases, QPV is detected accidentally during cardiac procedures or post mortem. The authors present a case of QPV complicated with aneurysm of the pulmonary trunk, diagnosed with computed tomography in 70-year-old woman. Although the patient had undergone transthoracic echocardiography examinations several times in the past, only computed tomography allowed the detection of the anomalous valve. In addition, the examination confirmed aneurysm of the pulmonary trunk. To the best of our knowledge, this is the first case of QPV diagnosed in vivo with computed tomography.
