We report a 52-year-old male patient who had a quadricuspid aortic valve (QAV) associated with aortic regurgitation (AR) and left ventricular hypertrophy (LVH). A new accessory cusp (ACC) with maximum thickness than other cusps was located between right coronary cusp (RCC) and left coronary cusp (LCC). The histopathological features revealed markedly thickened and distorted cusp architecture with fibrosis and/or myxomatous degeneration in both non-coronary cusp (NCC) and ACC. Two equal sizes for larger cusps (RCC and NCC) and two equal sizes for smaller cusps (LCC and ACC) were obtained...

To our knowledge, this is the first documented case of successful TAVI for severe quadricuspid aortic valve (QAV) stenosis performed in the U.S. and the first documented Sapien 3 valve implantation in a severely stenotic QAV.

Quadricuspid aortic valve (QAV) is a rare occurrence, usually presenting with insufficiency rather than stenosis. We report a case of aortic valve replacement in a septuagenarian with a stenotic QAV, achieving a good result with a Sorin Perceval sutureless bioprosthesis. We emphasize the particular technique of implantation and possible pitfalls. Sutureless bioprosthetic valves present a feasible option for aortic valve replacement in patients with uncommon valve morphologies, aiming to reduce operative time...

Quadricuspid aortic valve (QAV) is a rare congenital anomaly frequently associated with other anomalies particularly coronary anomalies. It may be detected on transthoracic or transesophageal echocardiography. We present here a case report of a 27-year-old male patient with a QAV, the valve being regurgitant and requiring aortic valve replacement. It has been reported as isolated case reports in the literature and various theories exist to the development of QAV. The diagnosis requires a high degree of suspicion and a detailed assessment, and if asymptomatic, then patients need to be carefully followed up for the development of aortic regurgitation...

We report two cases of a quadricuspid aortic valve with severe aortic incompetence. Both patients presented with dyspnea on exertion. Their physical examinations demonstrated wide pulse pressures with diastolic murmurs. Bedside transthoracic Doppler echocardiography revealed preserved left ventricular systolic function and possible quadricuspid aortic valve with severe aortic incompetence in both patients. We proceeded with transesophageal echocardiography that confirmed a quadricuspid aortic valve with severe aortic incompetence in both patients...

We report a 15-month-old female with unruptured noncoronary sinus of Valsalva anreurysm (SOVA) associated with quadricuspid aortic valve, ascending aortic aneurysm (AAA), moderate aortic insufficiency, mild mitral insufficiency, genetic leukoencepaholpathy, developmental delay and mild mixed aminoaciduria. She was referred for evaluation of a cardiac murmur. Initial echocardiographic examination showed the aneurysm as a round cyst in the right atrium which changed in size during systole and diastole. As to the best of our knowledge, this is the first report of association of SOVA, quadricuspid aortic valve, AAA and genetic leukoencephalopathy in an infant...

Quadricuspid aortic valve is a rare congenital disease. We experienced 3 surgical cases of quadricuspid aortic valve. Patient 1 was a 72-year-old man who was noted to have a quadricuspid aortic valve associated with aortic regurgitation and an ascending aortic aneurysm(51 mm in diameter). He underwent replacement of the aortic valve and the ascending aorta. Patient 2 was a 71-year-old man with severe aortic stenosis, regurgitation, and coronary triple vessel disease. He underwent aortic valve replacement and coronary artery bypass grafting...

Quadricuspid aortic valve (QAV) is a rare congenital aortic valve abnormality. It is less common as compared to bicuspid or unicuspid aortic valve abnormality. QAV causes aortic regurgitation usually in the fifth to sixth decade of life. We present a rare case of a female patient with cryptogenic stroke due to a QAV and a patent foramen ovale (PFO). The patient underwent transcatheter closure of PFO, as there was no clear indication for surgery for her valve. Surgical removal remains the method of choice for the treatment of the QAV before left ventricular decompensation occurs...

Infective endocarditis complicating a quadricuspid aortic valve (QAV) is rare. Previous reports highlight the increased risk for complications, including progressive aortic regurgitation, decompensated heart failure, and valve perforation. Thus, cardiologists must be able to quickly identify QAVs to guide rapid evaluation and treatment. We report a case of infective endocarditis in a QAV identified on echocardiography and effectively managed with medical therapy alone without complications over an 8-year follow-up period...

The quadricuspid aortic valve (QAV) is a very uncommon congenital malformation with an estimated incidence of 0.003% to 0.043% of all congenital heart diseases. Combinations of QAV with several different congenital malformations have been described. The case is reported of a type A QAV associated with moderate aortic regurgitation, mild mitral regurgitation, and ascending aorta dilatation. This interesting case was referred for close follow up.

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...
