Summary
Transcatheter aortic valve implantation (TAVI) is effective for bicuspid aortic valve (BAV) patients with large aortic annuli. The SAPIEN 3 prosthesis showed successful sealing, reducing leakage risks in these challenging cases.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Devices
Background:
- Transcatheter aortic valve implantation (TAVI) for bicuspid aortic valve (BAV) with large aortic annuli presents significant challenges.
- Residual paravalvular aortic leakage is a primary concern in these procedures.
Purpose of the Study:
- To evaluate the efficacy and safety of TAVI using the SAPIEN 3 prosthesis in patients with BAV and large aortic annuli.
- To assess the sealing capability of the SAPIEN 3 prosthesis in the unique anatomy of BAV.
Main Methods:
- Successful implantation of a SAPIEN 3 prosthesis in two patients diagnosed with BAV and a large aortic annulus.
- Focus on the prosthesis's sealing performance at the inter-commissural space.
Main Results:
- The SAPIEN 3 prosthesis was successfully implanted in both patients with BAV and large aortic annuli.
- Effective sealing was observed at the inter-commissural level, mitigating leakage risks.
Conclusions:
- TAVI with the SAPIEN 3 prosthesis is a viable option for BAV patients with large aortic annuli.
- The design of the SAPIEN 3, particularly its sealing at the inter-commissural space, contributes to successful outcomes in these complex cases.

The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

1.0K
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...

01:27Mitral Valve Prolapse I: Introduction
820
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

01:20Mitral Regurgitation I: Introduction
807
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

01:22Aortic Regurgitation II: Clinical Features and Diagnostic Tests
731
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...
