We report a case of a 26-year-old woman who presented with multiple episodes of syncope over a five-months period of time. Transthoracic echocardiogram had shown a normal functioning quadricuspid aortic valve (QAV) which was also confirmed on a transesophageal echocardiogram. Computed tomographic angiography of heart and coronary arteries showed the QAV with equal size of all aortic cusps and normal coronary arteries. Intermittent chest pain and palpitations warranted an exercise stress test. The stress test revealed normal aerobic exertion, with achievement of 101% of maximal peak heart rate...

An accessory coronary cusp in aortic valve is a rare congenital cardiovascular malformation with an estimated incidence of 0.003 to 0.043% of all congenital heart disease. It is also describe as a quadricuspid aortic valve (QAV). Several different anatomical variations of quadricuspid aortic valve have been described. Current technology enables noninvasive diagnosis in most cases. Here we reported a rare an isolated congenital type 'C' QAV with aortic regurgitation; hence it was worth reporting this interesting case...

BACKGROUND: After aortic valve replacement (AVR), bicuspid aortic valve (BAV) patients continue to be at risk of aortic complications. Therefore, knowledge of native valve anatomy is important for follow-up. We aimed to determine the extent of which the presence of BAV disease is known in a regional post-AVR population. METHODS: The Electronical Medical Record system was used to collect all patients under follow-up after AVR. We documented their clinical data and used the operative report to determine valve phenotype; lacking reports were retrieved...

We report a case of a 35-year-old active duty male with a rare quadricuspid aortic valve identified via transthoracic echocardiography following the detection of an incidental grade I/VI diastolic murmur. Further characterization of the anatomical findings and aortic valve flow dynamics were evaluated with cardiac magnetic resonance imaging. Accurate assessment of the various valve morphologies is essential, as it guides surgical treatment options to correct the defect. Our case highlights the complimentary role of cardiac magnetic resonance imaging in defining the anatomy and functional consequences of a quadricuspid aortic valve...

The quadricuspid aortic valve is a very uncommon malformation associated with aortic insufficiency, aortic stenosis, endocarditis, and ascending aortic dilatation. We report four cases of this aortic valve malformation. One patient with severe aortic regurgitation and moderate aortic dilatation required aortic valve replacement. Three patients had mild or moderate aortic insufficiency combined with moderate ascending aortic dilatation. These patients were referred to follow-up. The presented cases demonstrate that this aortic valve malformation may not be as rare as it appears and that attention must be paid to any quadricuspid findings during computed tomographic angiography and echocardiography...

OBJECTIVE: The aim of this study was to identify the morphological and functional characteristics of quadricuspid aortic valves (QAV) on cardiac computed tomography (CCT). MATERIALS AND METHODS: We retrospectively enrolled 11 patients with QAV. All patients underwent CCT and transthoracic echocardiography (TTE), and 7 patients underwent cardiovascular magnetic resonance (CMR). The presence and classification of QAV assessed by CCT was compared with that of TTE and intraoperative findings...

A 65-year-old woman was admitted due to electrocardiographic abnormality and exertional dyspnea. Transthoracic echocardiography revealed quadricuspid aortic valve malformation with severe aortic regurgitation. All 4 cusps were of equal size, and the quadricuspid valve was classified as type a by Hurwitz classification. We replaced it with an 18 mm mechanical valve and her postoperative course was uneventful.

Quadricuspid aortic valve (QAV) is an anatomic valvular variant, with a prevalence of 0.008% to 0.033% in the general population, and 1.46% in patients that undergo aortic valve replacement. The QAV can be an isolated valvular abnormality or associated with other congenital heart defects. In this article, we present three of the few reported cases of QAV in the Hispanic population, all of which were asymptomatic and without evidence of hemodynamic alterations or other associated heart defects. Additionally a literature review is provided...

Congenital quadricuspid aortic valve is a very rare malformation. In most cases it has been found incidentally at aortic valve surgery or at autopsy. It frequently causes aortic regurgitation, which may become manifest in adulthood and require surgical treatment. We reported 4 cases of aortic regurgitation with quadricuspid aortic valve. In all cases, aortic valve replacement was preformed with prosthetic valve, and their postoperative courses were uneventful. Two were Hurwitz's classification type b, one was type a and the last patient was type c...

Quadricuspid aortic valve (QAV) is a rare congenital cardiac anomaly causing aortic regurgitation usually in the fifth to sixth decade of life. Earlier, the diagnosis was mostly during postmortem or intraoperative, but now with the advent of better imaging techniques such as transthoracic echocardiography, transesophageal echocardiography (TEE), and cardiac magnetic resonance imaging, more cases are being diagnosed in asymptomatic patients. We present a case of a 39-year-old male who was found to have QAV, with the help of TEE, while undergoing evaluation for a diastolic murmur...

We report 2 cases (a 59-year-old man and a 61-year-old man) of quadricuspid aortic valve that had aortic regurgitation. Preoperative transthoracic or transesophageal echocardiography was useful for diagnosing definitely and deciding treatment plan. Their aortic valves were type F in each according to the Hurwitz-Roberts classification. They underwent aortic valve replacement and had good postoperative courses.

A 69-year-old woman with general fatigue was admitted to our hospital for further examination of mediastinal lymph node swelling. Mediastinal lymph node sampling was planned. Preoperative transthoracic echocardiography revealed severe aortic regurgitation, and aortic valve replacement combined with mediastinal lymph node sampling was performed. Following lymph node sampling, the ascending aorta was opened, and the aortic valve was found to be quadricuspid. An accessory cusp was existed between the left coronary cusp and the non coronary cusp...

A 58-year-old man presented with severe aortic regurgitation(AR) with quadricuspid valve. Intraoperatively, the small accessory cusp was separated from non-coronary cusp( NCC). The NCC and small accessory cusp were sutured to obtain 1 competent cusp, aiming at an effective height of 8 mm. His AR was trivial at the postoperative 7th day.

BACKGROUND: Quadricuspid aortic valve (QAV) is a rare congenital cardiac defect. This study sought to determine QAV frequency in a large echocardiography database, to characterize associated cardiovascular abnormalities, and to describe long-term outcomes. METHODS AND RESULTS: Fifty patients (mean ± SD age, 43.5 ± 21.8 years at the time of the index diagnosis; female sex, 52%) received a diagnosis of QAV between January 1, 1975, and March 14, 2014 (frequency, 0...

Quadricuspid aortic valve is a rare congenital heart defect. The authors present a case of this anomaly in a young, asymptomatic adolescent who presented to the echocardiography laboratory for further evaluation of a cardiac murmur detected on routine physical examination. Imaging revealed a quadricuspid aortic valve with aortic regurgitation. This case highlights the importance of auscultation in detecting cardiac abnormalities.
