Valvular regurgitation is a recognized complication of aortic and mitral valve procedures, with paravalvular leak the primary mechanism and transvalvular less common. The Cor-knot automated fastener (LSI SOLUTIONS, Victor, NY, USA) has been shown to be a safe, viable alternative to knot pushers or manual tying for use in these procedures. Here we present two cases in which Cor-Knot fastener orientation appeared to result in transvalvular regurgitation necessitating redo operation. With adjunctive use of Cor-Knot devices, fastener orientation relative to valve geometry must be assessed for optimal results...

OBJECTIVE: Transcatheter aortic valve implantation (TAVI) has been adopted rapidly in Europe. TAVI national registries can augment understanding of technologies and represent real-world experience, providing further clinical insights. We undertook a meta-analysis of published European national TAVI registries to assess current results following TAVI in Europe. METHODS: Electronic databases were searched. The review focused on the comparison of the following TAVI strategies: transfemoral (TF) and transapical (TA) SAPIEN and CoreValve implantation...

A 40-year-old man with osteogenesis imperfecta type I submitted to multiple procedures of surgical mitral and aortic valve replacement was referred for refractory congestive heart failure due to significant paravalvular leaks (PVLs) of both mitral and aortic prostheses. Due to perceived very high risk of a further mitroaortic surgery, transcatheter closure of PVLs under three-dimensional echocardiographic guide was performed. Thus, four Amplatzer Vascular Plug type II (St. Jude Medical Corp, St. Paul, Minnesota, USA) devices were implanted into the aortic PVLs, and three Amplatzer Vascular Plug type II devices were used to occlude a huge mitral PVL...

Paravalvular leak (PVL) is a serious complication after surgical valve replacement or after transcatheter aortic valve replacement. Approximately 1-5% of PVLs can lead to serious clinical consequences, including congestive heart failure and/or haemolytic anaemia. For years, surgical re-intervention has been considered the treatment of choice for symptomatic patients with PVLs. However, surgical re-intervention is associated with a high risk of morbidity and mortality. Transcatheter PVL (TPVL) closure is a less invasive alternative to surgical re-intervention...

Transcatheter aortic valves (TAVs) represent the latest advances in prosthetic heart valve technology. TAVs are truly transformational as they bring the benefit of heart valve replacement to patients that would otherwise not be operated on. Nevertheless, like any new device technology, the high expectations are dampened with growing concerns arising from frequent complications that develop in patients, indicating that the technology is far from being mature. Some of the most common complications that plague current TAV devices include malpositioning, crimp-induced leaflet damage, paravalvular leak, thrombosis, conduction abnormalities and prosthesis-patient mismatch...

Percutaneous pulmonary valve implantation is now an acceptable treatment option. The Edwards SAPIEN valve, intended for transcatheter aortic valve implantation, has been used in patients whose landing zone diameter is >22 to 24 mm which is not suitable for Melody valve. We report a patient in whom we successfully placed the latest generation, Edwards SAPIEN 3 (ES3) in the pulmonary position. However, because of the short covered portion of this valve, there was a significant paravalvular leak through the stent struts requiring implantation of a second ES3 valve...

For patients with paravalvular mitral prosthetic regurgitation, percutaneous repair is an established therapy for the treatment of symptoms of heart failure or hemolytic anemia. Percutaneous repair of paravalvular mitral regurgitation is a complex procedure with unique technical challenges, even when performed in experienced centers. Herein, the author discusses patient selection, catheter-based techniques for repair, and clinical outcomes of percutaneous repair for paravalvular mitral regurgitation.

This is a report of the first Brazilian experience with the Perceval sutureless aortic prosthesis in two patients with severe aortic stenosis. Transesophageal echocardiography was used during the procedure. The aortotomy was performed 1 cm above the sinotubular junction, followed by leaflets removal and decalcification. Correct valve size was selected, device released and an accommodation balloon used. The cardiopulmonary bypass times were 47 and 38 min and the cross-clamp times were 38 and 30 min. There was a significant decrease in mean gradients (41 and 75 mmHg preoperatively; 7 and 8 mmHg postoperatively)...

Although radiation dermatitis is a widely known complication of radiotherapy, its association with fluoroscopy-guided interventional procedures is yet underrecognized. We present a case of a 66-year-old man with a left scapular cutaneous lesion, initially diagnosed as a fixed drug eruption. The subsequent knowledge of a previous percutaneous aortic paravalvular leak closure procedure allowed a correct clinicopathological correlation and the final diagnosis of subacute radiodermatitis associated with fluoroscopy...

Best practices for transcatheter aortic valve implantation with CoreValve include patient screening and valve size selection using multislice computed tomography, adherence to manufacturer recommendations for oversizing, control of implant depth to 6 mm or less, and management of conduction disturbances according to international guidelines. The ADVANCE II study implemented these strategies and demonstrated their relation to clinical outcomes. From October 2011 to April 2013, 200 patients with severe aortic stenosis were enrolled, and 194 were implanted...

Paravalvular leak (PVL) remains as uncommon but serious complication after surgical prosthetic valve implantation. PVL when associated which congestive heart failure, hemolytic anemia, or infective endocarditis may require percutaneous treatment. High-surgical risk is common in this population. Dedicated PVL devices are lacking often limiting optimal treatment.
