BACKGROUND: The presence of a fourth aortic valve cusp (quadricupsid aortic valve) is a rare congenital malformation and is often accompanied by other anomalies of the adjacent cardiovascular structures. Among these concomitant anomalies, simultaneous association of both a single coronary ostium and aneurysmal ascending aortic dilation in combination with the quadricupsid aortic valve has not been reported yet. CASE PRESENTATION: We experienced the case of a 56-year-old female patient presenting as aortic regurgitation resulted from malcoaptation of quadricupsid aortic valve...

Aortocardiac fistulae (ACF) are exceptionally due to infective endocarditis; they are usually congenital, posttraumatic, or complicate aortic dissection. In infective endocarditis setting, their presence should prompt urgent surgery as patients can deteriorate rapidly. We report the case of a 78-year-old female patient with the first ever reported quadricuspid aortic valve infective endocarditis complicated by multiple aortocardiac fistulae. Additionally, we provide a brief review of ACF, in infective endocarditis and quadricuspid aortic valve...

Quadricuspid aortic valves (QAVs) are extremely rare. In this case study, we report a David-V valve-sparing aortic root replacement with reimplantation of a native QAV in a patient with aortic dilation, normal valve function, and a family history of aortic dissection. Microscopic pathological examination of the excised section of the aorta revealed scattered small foci of cystic medical degeneration throughout. A genetic predisposition for aortic dilation may be present in patients with QAV, even in the setting of a competent valve...

The patient was a 69-year-old man who had 1st experienced exertional dyspnea approximately 1 month earlier. He visited our hospital for treatment because his symptoms had gradually worsened and he had developed orthopnea. Echocardiography revealed an atrial septal defect(ASD) and a quadricuspid aortic valve with moderate regurgitation. As patch closure of the ASD alone could pose a risk of exacerbating the untreated aortic regurgitation, we performed both procedures patch closure and aortic valve replacement through median sternotomy concomitantly...

OBJECTIVE: We describe a simple method to assess the aortic valve using a videoscope inserted in the left ventricle (LV-VS) during valve-sparing root replacement. The aim of this study was to evaluate the feasibility of this technique by comparing it with the findings of postoperative transesophageal echocardiography (TEE). METHODS: Thirty-six patients (29 male, mean age 45.4 ± 20.1 years) undergoing aortic root reimplantation were assessed intraoperatively with LV-VS...

Quadricuspid aortic valve is a rare anomaly, and most patients require surgery for aortic regurgitation in the 5th or 6th decades of life; only a few cases of aortic valve repair in childhood have been reported. A 3-year-old boy was scheduled for ventricular septal defect closure and aortic valve repair. Quadricuspid aortic valve was an incidental finding at operation; it was repaired by joining the left anterior and right anterior cusps. At the 9-month follow-up, the patient had no more than mild aortic regurgitation...

A congenital quadricuspid aortic valve accompanied by ostial obstruction of the left coronary artery is extremely rare and has not yet been reported in an infant. We herein describe an infant with ostial obstruction of the left coronary artery caused by a small left coronary cusp that formed a pouch. The patient's cardiac function deteriorated due to progressive myocardial ischaemia, and translocation of the ostium of the left coronary artery was performed. Postoperative coronary angiography revealed good filling of the left coronary artery...

Quadricuspid aortic valve is an extremely rare congenital heart anomaly that often causes valve incompetence, requiring surgical intervention. Care must be taken to avoid surgical complications in patients with quadricuspid aortic valve; thus, preoperative diagnosis is important. A 76-year-old man presented with exertional dyspnea due to aortic regurgitation. Transthoracic and transesophageal echocardiography revealed severe aortic regurgitation caused by quadricuspid aortic valve. To avoid interference with the cardiac conduction system, we performed aortic valve replacement using an ingenious technique, in which pledgeted sutures on the accessory leaflet were placed from outside the sinus of Valsalva to above the aortic annulus...

Quadricuspid aortic valve (QAV) is a rare congenital heart disease. The functional status of QAV is predominantly a pure aortic regurgitation. Clinical manifestations of patients with a QAV depend on the functional status of the QAV and the associated disorders. Significant valvular regurgitation and (or) stenosis is often present with subsequent operation performed at the fifth to sixth decade of life. The functional status of QAV is predominantly regurgitant; whereas pure stenotic QAV can be as few as in only 0...

Quadricuspid aortic valve (QAV) is a rare congenital cardiac defect. Aortic regurgitation is the predominant hemodynamically relevant abnormality in patients with QAV, and the main reason for patients requiring valve surgery. Calcific valve disease of the left heart valves is classified as 'low embolic risk' according to current guidelines. However, it remains an important risk factor of cardiovascular events, including ischemic stroke. A 71-year-old woman presented with new-onset aphasia and hemiparesis of the right side of her body...

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...
