PURPOSE OF REVIEW: Sutureless aortic valve replacement (AVR) has emerged as an alternative to traditional AVR for patients with aortic stenosis who present a higher surgical risk, such as the elderly, or those with small or highly calcified aortic roots. With transcatheter aortic valve implantation - the other major AVR alternative - being used in increasingly lower-risk patients, the place of sutureless valves in the AVR landscape needs to be defined. In this review, we discuss recent data and expert opinion as it pertains to the subject of sutureless AVR...

BACKGROUND: With improving technologies and an increasingly elderly populations, there have been an increasing number of therapeutic options available for patients requiring aortic valve replacement. Recent evidence suggests that transcatheter aortic valve implantation (TAVI) is one suitable option for high risk inoperable patients, as well as high risk operable patients. Sutureless valve technology has also been developed concurrently, with facilitates surgical aortic valve replacement (SUAVR) by allow resection and replacement of the native aortic valve with minimal sutures and prosthesis anchoring required...

Paravalvular leak (PVL) following aortic valve implantation is a rare complication but may cause potentially serious consequences. It occurs in 2%-10% of surgical aortic valve replacements and 7%-17% of surgical mitral valve replacements. Transcatheter valve replacement data show that significant PVL occurs in 6%-8% of cases. The management of significant PVL has traditionally involved repeat surgical repair. However, many of these patients are considered too high risk to undergo a repeat surgical procedure; hence, a percutaneous transcatheter approach has often been utilized to treat these patients...

A 79-year-old man underwent trans-catheter aortic valve replacement for symptomatic severe aortic stenosis with a 26-mm Edwards SAPIEN XT valve. Immediately after valve deployment there was moderate amount of paravalvular leak. Post-dilation was performed with an additional 2 cc of volume, and the paravalvular leak was reduced to trace. Nine months later, trans-thoracic echocardiography revealed moderate to severe paravalvular leak and possible aortic migration of the valve. The patient was brought back for the treatment of the paravalvular leak which was suspected to be due to valve migration...

New generation of the most widely used devices for transcatheter aortic valve implantation have been recently introduced into practice. We compare the short-term outcomes of transcatheter aortic valve implantation with the Edwards SAPIEN S3 and the Medtronic Evolut-R. We performed a retrospective analysis from a single high-volume tertiary center. Valve Academic Research Consortium-2 criteria were used to define composite end points of device success and safety at 30 days. Study population included 232 patients implanted with the SAPIEN S3 (n = 124) and Evolut-R (n = 108)...

BACKGROUND: Carcinoid tumor is a slow-growing type of neuroendocrine tumor, originating from enterochromaffin cells and secreting mainly serotonin. The diagnosis is based on clinical symptoms, hormone blood levels, radiological and nuclear imaging, and histological confirmation. However, most patients have metastases at the time of diagnosis because the clinical signs often remain unnoticed or are attributed to other abdominal conditions. In up to 50% of patients the endocardium is affected due to a hormonally active tumor profile...

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...

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...

OBJECTIVES: To compare outcomes after minimalist and standard transfemoral transcatheter aortic valve replacement (TF-TAVR) in patients with severe chronic obstructive pulmonary disease (COPD). BACKGROUND: TF-TAVR is increasingly performed with conscious sedation and transthoracic echocardiography guidance (minimalist). The safety/efficacy of this technique in patients with severe COPD is unknown. METHODS: We compared demographics, 30-day outcomes and 1-year survival of patients with severe COPD (FEV1% ≤50) who underwent minimalist vs...
