Abstract Background  Aortic stenosis (AS) is one of the most common valvular disorders worldwide. An increasing number of transcatheter aortic valve implantation (TAVI) procedures are being performed yearly for managing AS. This, along with the occurrence of common complications, makes timely diagnosis essential to manage rare complications and improve patient outcomes. Case summary  We present a case of a 77-year-old Caucasian male with severe AS with a dysfunctional bioprosthetic valve following previous surgical valve replacement. During valve-in-valve TAVI, we noted bioprosthetic valve leaflet avulsion and embolization causing a major vascular occlusion that resulted in vascular insufficiency of the left lower extremity. This condition was managed successfully via immediate diagnosis using transoesophageal echocardiogram, angiogram, and vascular surgical intervention for retrieving the embolized valve to re-establish circulation. Discussion  To our knowledge, this is the first case of aortic valve leaflet embolization during TAVI resulting in significant vascular insufficiency. Vascular complications are common during TAVI. However, not all vascular complications are the same. Our case highlights an embolic vascular complication from an avulsed prosthetic material during a challenging valve-in-valve TAVI procedure.

Transcatheter aortic valve implantation (TAVI) and endovascular aortic repair (EVAR) are increasingly being used as therapeutic options for patients with severe aortic stenosis who are ineligible for surgery and who have aortic aneurysm with suitable anatomical features. These procedures can be associated with severe complications, especially related to vascular access and the use of a large introducer sheath (from 18 to 24 French [Fr]). In this article we describe possible vascular complications emerging during TAVI and EVAR and their appropriate management, beginning with patient selection, the correct way to perform vessel puncture and the use of a vascular closure device, up to the recently proposed cross-over technique, which is thought to minimise the risk of dangerous consequences of vascular damage.

Abstract Background Failure of a small surgical aortic bioprosthesis represents a challenging clinical scenario with valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) often resulting in patient-prosthesis mismatch. Bioprosthetic valve fracture (BVF) performed as a part of the ViV TAVI has recently emerged as an alternative approach with certain types of surgical bioprostheses. Case summary An 81-year-old woman with a history of three surgical aortic valve procedures presented with heart failure. Aortic bioprosthesis degeneration with severe stenosis and moderate regurgitation was found. The patient was deemed a high-risk surgical candidate and the heart team decided that ViV TAVI was the preferred treatment option. Due to the very small 19 mm stented surgical aortic bioprosthesis Mitroflow 19 mm (Sorin Group, Italy) we decided to perform BVF as a part of ViV TAVI to prevent patient-prosthesis mismatch. Since this was the first BVF procedure in our centre, an ex vivo BVF of the same kind of bioprosthetic valve was performed first. Subsequently, successful BVF with implantation of Evolut R 23 mm (Medtronic, USA) self-expandable transcatheter valve was performed. Excellent haemodynamic result was achieved and no periprocedural complications were present. The patient had an immediate major improvement in clinical status and remains asymptomatic after 6 months. Discussion Bioprosthetic valve fracture together with ViV TAVI is a safe and effective emerging technique for treatment of small surgical aortic bioprosthesis failure. Bioprosthetic valve fracture allows marked oversizing of implanted self-expandable transcatheter aortic valves, leading to excellent haemodynamic and clinical results. An ex vivo BVF can serve as an important preparatory step when introducing the new method.

Abstract Background Fatal thrombo-embolic events like cerebral stroke or myocardial infarction are rare complications of prosthetic heart valve leaflet thrombosis. Nevertheless, prevention and management of leaflet thrombosis is gaining increased attention, particularly with the widespread adoption of transcatheter heart valves. Case summary We herein present the case of a 79-year-old man who had undergone a transcatheter aortic valve implantation procedure. Seven months later, he presented with a non-ST-segment elevation myocardial infarction. Coronary angiography did not reveal obstructive lesions. A dedicated cardiac computed tomography scan showed thrombosis of both right- and non-coronary leaflets of the prosthetic aortic valve, while prosthetic valve function was normal on echocardiography. Transmural myocardial infarction lesions in the midventricular and apical inferior wall were detected by cardiac magnetic resonance imaging. Discussion Subclinical leaflet thrombosis of prosthetic aortic valves is a common finding. In this case report, we show that myocardial infarction presumably due to leaflet thrombosis was the first symptom in an otherwise asymptomatic patient. This finding raises the question of the validity in distinguishing between subclinical and clinical leaflet thrombosis based on prosthetic valve function.
