Early Detection of Left Ventricular Systolic Dysfunction in Asymptomatic Patients with Chronic Aortic Regurgitation by two Dimensional Speckle Tracking Echocardiography

Objective: By two-dimensional speckle tracking echocardiography, it was possible to find early LV systolic dysfunction in an asymptomatic patient with persistent aortic regurgitation. Methods: Sixty one asymptomatic patients with chronic aortic regurgitation, no ischemic heart diseases or conductive heart diseases, no diabetes mellitus, no hypertension, no hypertension, and no other valvular heart diseases were included in the study, as well as matched healthy controls. Results: In moderate AR, GLS demonstrated the highest sensitivity and specificity in the detection of subtle LV systolic dysfunction. In all forms of AR, GLS had higher NPV than PPV, making it a more effective screening device for early detection of subtle LV systolic dysfunction. Conclusion: Global Longitudinal strain measured by 2-D speckle tracking echocardiography is a powerful tool for early detection of subtle LV systolic dysfunction in asymptomatic patients with persistent AR.

Transcatheter Aortic Valve Implantation for Severe Pure Aortic Regurgitation with Dedicated Devices

Once AR symptoms develop, the prognosis becomes poor. Transcatheter aortic valve implantation for patients with pure AR and at high risk of surgical risk is occasionally performed, but it remains a clinical challenge due to a lack of valvular calcium, a large aortic root, and increased stroke volume. These topics make the selection and installation of transcatheter aortic valve implant kits difficult, with a tendency to prosthesis embolization or malposition. The J-Valve and the JenaValve are AR's only two dedicated transcatheter valves for AR to date.

New Challenging Scenarios in Transcatheter Aortic Valve Implantation: Valve-in-valve, Bicuspid and Native Aortic Regurgitation

Transcatheter aortic valve implantation is the most commonly used structural procedure in interventional cardiology. These include valve-in-valve procedures, lower-risk patients with bicuspid aortic valve, and pure aortic regurgitation. Whereas the valve-in-valve indication has risen quickly, evidence for the use of TAVI in comparison to traditional surgery for bicuspid aortic valve is limited, including the right choice of device should TAVI be used. Operators around the world have reported variations in the TAVI procedural system to achieve commissural alignment and minimize the rate of pacemaker usage by cusp overlap implantation.

TAVI for Pure Native Aortic Regurgitation: Are We There Yet?

Transcatheter aortic valve implantation has improved treatment of degenerative aortic stenosis by transcatheter aortic valve implantation over the past ten to fifteen years. However, the changes in the valve complex in pure native aortic regurgitation are similar to those in degenerative aortic stenosis, and percutaneous valves pose particular challenges to be overcome.

Sutureless aortic valve replacement in pure aortic regurgitation: expanding the indications

Abstract Background In the era of transcatheter technologies, patients with a pure aortic regurgitation are not eligible for transcatheter therapy and, therefore, require another less invasive surgical option. We wanted to investigate our experiences with sutureless aortic valve replacement in patients with symptomatic pure AR, which has been a hindrance to implanting sutureless valve prostheses in Europe for patients. We investigated the results and postoperative complications of 12 patients with a pure severe AR undergoing SU-AVR using Perceval. No patients were diagnosed with a valvular leakage. Our experience with SU-AVR shows the possibility of sutureless techniques in the aortic valve surgery due to pure AR. SU-AVR in severe AR offers a great chance of lowering the surgical cost and potentially lowering hospital costs without compromising the postoperative outcomes and in-hospital length of stay, which is besides the excellent scientific results and outstanding hemodynamics.
