“…As with TTE, the frequency of valve morphology in cases diagnosed using CT scan or CMR was largely different from that in cases diagnosed at autopsy (Table 3 ) [ 13 - 16 , 40 - 55 ]. It might be reasonable to actively look for QPV in patients who have marked aneurysmal dilatation of the main pulmonary artery, with or without an extension of the dilatation into pulmonary artery branches [ 54 ]. Table 4 shows differences in the frequency of QPV using diagnostic methods.…”

Background: Quadricuspid pulmonary valve (QPV) is a rare congenital anomaly. Simple QPV had been mainly diagnosed at the time of autopsy before 2000 and the frequency rates of QPV are approximately 0.02%–0.41%. QPV was initially diagnosed using transthoracic echocardiography (TTE) after 2000 and with contrast computed tomography (CT) or cardiac magnetic resonance imaging (CMR) after 2009. Obtaining the cross-sectional view of the pulmonary valve using TTE is difficult. We aimed to review the papers regarding the incidence, embryology, diagnosis, associated congenital heart anomalies, and prognosis in patients with QPV, and furthermore to compare with those in patients with quadricuspid aortic valve (QAV). Case presentation: We diagnosed QPV with mild stenosis in a 12-month-old infant. With a slight angulation of the transducer superiorly from the left high parasternal short-axis view, a short-axis view of QPV was obtained. Results: In QPV cases diagnosed at autopsy, Hurwitz’s type-b with three equal cusps and one smaller cusp is dominant, whereas Hurwitz’s type-a with four equal cusps is dominant in clinically diagnosed cases. Patients with associated congenital heart anomaly and valvular stenosis are more frequent in patients with QPV than in patients with QAV. Coronary artery anomalies and infectious endocarditis are more frequent in patients with QAV than in patients with QPV. The incidence of PR is more common in type-a QPV than in type-b QPV. There is no difference between type-a QAV and type-b QAV with respect to the incidence of aortic regurgitation (AR). It is assumed that QPV is a risk factor for a Ross operation. However, QPVs have been used as autografts in certain patients. Conclusion: Between QPV and QAV, various differences were found about frequency rates, diagnostic methods, valve morphology, valve function, associated congenital heart diseases, and frequencies of infectious endocarditis.

A 17‐year‐old male presented to our hospital from an external center with complaints of chest pain and shortness of breath, referred with preliminary diagnoses of pulmonary stenosis and pulmonary artery dilation. Echocardiography revealed moderate pulmonary regurgitation and mild pulmonary stenosis. Coronary computed tomography (CT) angiography showed normal coronary arteries and no presence of a patent ductus arteriosus, but an aneurysmal dilation of up to 4 cm was observed in the pulmonary artery. The patient was found to have a quadricuspid (QPV) pulmonary valve, while the aortic valve appeared normal. No phenotypic anomalies or accompanying aortic or lung abnormalities were detected in this case. Our case represents the first in the pediatric age group diagnosed via CT scan. Our study contributes insights into the relationship between QPV anomaly and pulmonary artery aneurysm, aiding in the diagnosis and management of these rare conditions. Furthermore, our findings highlight the importance of evaluating the possibility of QPV in patients with pulmonary valve stenosis, regurgitation, or artery aneurysm, emphasizing the significance of coronary CT angiography in the diagnostic process.

A quadricuspid pulmonary valve (QPV) is a rare congenital cardiac anomaly, mostly identified incidentally during autopsy or imaging examination. The authors report on an autopsy case report describing a case of a QPV recognised incidentally during the autopsy of a 91-year-old male with bilateral pneumonia. All four cusps of the pulmonary valve exhibited approximately equal sizes and showed no degenerative changes, while the remaining heart valves displayed no structural anomalies. There was no clinical or pathological evidence of stenosis or regurgitation. In this report, the authors discuss the clinical presentation, review the existing literature, investigate the diagnostic and clinical implications of QPV, and highlight the key factors involved in QPV embryogenesis.
