What is the optimal management for a patient with quadricuspid aortic valve (QAV) and severe aortic regurgitation (AR) with advanced Human Immunodeficiency Virus (HIV) infection?

From the Guidelines

The abstract is well-structured and effectively communicates the complex case of a quadricuspid aortic valve (QAV) with severe aortic regurgitation in an immunocompromised HIV patient, highlighting the importance of multidisciplinary decision-making and timely intervention. The case summary provides a clear overview of the patient's clinical course, from initial detection to successful surgical management, including relevant clinical parameters like CD4 counts and viral load that influenced treatment timing. The abstract appropriately emphasizes the importance of physical examination in detecting valvular disease, the role of imaging in diagnosis, and the value of a multidisciplinary team approach in managing high-risk patients, as supported by the 2017 ACC expert consensus decision pathway for transcatheter aortic valve replacement 1. The management of patients with severe valvular disease, such as the one presented, is best achieved by a collaborative team that includes cardiologists, structural interventional cardiologists, imaging specialists, cardiovascular surgeons, and other healthcare professionals, as recommended by 1. The use of a multidisciplinary team approach allows for shared decision-making, taking into account the patient's preferences, values, and expectations, as well as the risk-benefit ratio of different treatment strategies, as outlined in 1. In terms of treatment, surgical aortic valve replacement (AVR) is a viable option for patients with severe aortic regurgitation, even in those with significant immunosuppression, as long as there is a multidisciplinary team approach and careful consideration of the patient's overall health status, as suggested by 1. The abstract's emphasis on the importance of timely intervention, even in high-risk immunocompromised patients, is supported by the patient's successful outcome, highlighting the need for careful monitoring and management of these patients, as implied by 1 and 1. Overall, the abstract effectively presents a complex case and highlights the importance of a multidisciplinary team approach in managing patients with severe valvular disease, particularly in those with significant immunosuppression.

From the Research

Abstract Review

The provided abstract appears to be well-structured and effectively conveys the key points of the case study. However, some minor corrections may be necessary to improve clarity and adherence to standard abstract guidelines 2.

• The abstract could benefit from a clearer separation between the background, case summary, and conclusion sections.
• The use of specific details, such as the patient's CD4 count and viral load, adds depth to the abstract but may not be essential for a general audience.
• The conclusion effectively highlights the importance of physical examination, imaging, and multidisciplinary decision-making in managing complex cases like quadricuspid aortic valve (QAV) 3, 4, 5.

Quadricuspid Aortic Valve (QAV) Management

The management of QAV is complex and often requires individualized decision-making. Studies have shown that QAV is frequently associated with aortic regurgitation and may require surgical intervention, such as aortic valve replacement or repair 3, 4, 5.

• The choice of surgical procedure depends on various factors, including the patient's overall health, the severity of valvular disease, and the presence of associated cardiovascular abnormalities.
• Recent studies have explored the use of geometric ring annuloplasty to facilitate QAV repair, which may offer superior patient outcomes compared to replacement 6.
• The importance of antibiotic prophylaxis against infective endocarditis in QAV patients with unequal-sized cusps should not be overlooked 3.

Immunocompromised Patients

The case study highlights the challenges of managing QAV in immunocompromised patients, such as those with advanced HIV infection.

• The decision to defer surgical intervention due to significant immunosuppression and high viral load is consistent with standard practice.
• The successful outcome of the patient after modest immune reconstitution and bioprosthetic AVR demonstrates the importance of timely intervention and multidisciplinary care in high-risk patients 5.
