Project description:A quadricuspid aortic valve is rarely diagnosed in children, but it can be associated with significant aortic regurgitation. It is important for pediatric cardiologists to be aware of this pathologic entity. We present a nine-year-old male, diagnosed with a quadricuspid aortic valve and mild aortic regurgitation.

Percutaneous Intervention of Aortic Pseudoaneurysm and Severe Bioprosthetic Valve Regurgitation Following a Bentall Procedure.

Project description:A 77-year-old man with a history of a Bentall procedure presented with acute decompensated heart failure. Investigations revealed severe bioprosthetic aortic valve regurgitation and a large pseudoaneurysm eroding the sternum. We describe the multimodal imaging and heart team planning to stent the pseudoaneurysm with an endograft followed by transcatheter valve-in-valve implantation.

Raphal Cord Rupture: A Rare Mechanism of Aortic Regurgitation in Bicuspid Aortic Valve.

Project description:A 70-year-old male with chronic aortic regurgitation was referred with abrupt worsening heart failure. Late referral markers were pulmonary hypertension, mitral regurgitation, and tricuspid regurgitation. Evaluation revealed rupture of a raphal cord or fenestrated raphe from the conjoined cusp of a congenitally bicuspid aortic valve, a rare mechanism of aortic regurgitation. (Level of Difficulty: Intermediate.).

A Rare Case of Post-Mitral Valve Replacement Ventricular Pseudoaneurysm, Bioprosthetic Dehiscence, and Paravalvular Mitral Regurgitation.

Project description:We present a rare case of a young patient who underwent a bioprosthetic mitral valve replacement and subsequently experienced a left ventricular pseudoaneurysm complicated by valve dehiscence and paravalvular mitral regurgitation, demonstrated by multimodality imaging and confirmed during surgical repair. (Level of Difficulty: Advanced.).

Leaflet disruption of ViV-TAVI after bioprosthetic valve fracture leading to severe aortic regurgitation: a case report.

Project description:BackgroundValve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) has emerged as an alternative for the treatment of degenerated bioprosthetic valves (BPVs) for high surgical risk patients. However, this procedure often results in patient-prosthesis mismatch. BPV fracture is a novel technique to address this problem. From now, complications following BPV fracture are few.Case summaryWe present the case of a 84-year-old female with history of first surgical aortic BPV replacement with a Mitroflow Sorin 23 mm due to severe aotic stenosis in 2009. In 2017, a second intervention due to bioprosthetic aortic valve stenosis valve was performed with valve-in-valve TAVI with CoreValve Evolut R 23 mm. In 2021, she was admitted with severe heart failure due to TAVI degeneration with severe stenosis in the bioprothesis. After heart team discussions, the patient was deemed inoperable for new heart surgery and considered as a candidate for BPV fracture as last possible alternative. After BPV fracture was performed, the patient suffered acute hypotension. Urgent transoesophageal echocardiography and angiogram demonstrated severe acute intra-TAVI aortic insufficiency because of probable disruption of the CoreValve leaflets. The patient was successfully treated with a ViV 23 mm SAPIEN three Edwards valve with a resolution of the aortic insufficiency and improvement of her haemodynamics. The patient remains asymptomatic after 6 months, with improvement in clinical status.DiscussionThis case demonstrates a disruption of the transcatheter heart valve leaflets causing severe aortic regurgitation as one of the complication of BPV fracture. To our knowledge, this is the first report of a TAVI in a patient who was already operated with ViV-TAVI. Although case series described few complications with improvement in clinical status, the procedure should be established with appropriate planning and careful technique.
