AIMS: Safety and efficacy of single vs. dual antiplatelet therapy (DAPT) in patients undergoing TAVI remain to be addressed. METHODS AND RESULTS: All consecutive patients enrolled in the ITER registry were included. Patients undergoing TAVI discharged with aspirin alone were compared to those assuming DAPT before and after selection with propensity score with matching. Subgroup analysis was performed for those on OAT. Prosthetic heart valve dysfunction at follow-up was the primary end point whereas all cause death, cardiovascular death, bleedings, vascular complications and cerebrovascular accidents were the secondary ones...

BACKGROUND: The role of three-dimensional transesophageal echocardiography (3DTEE) vs multidetector computed tomography (MDCT) in aortic annular sizing has been poorly defined in patients undergoing transcatheter aortic valve replacements (TAVR). We set to determine the correlation between 3DTEE and MDCT in measuring the aortic annulus prior to TAVR. METHODS: In an observational, retrospective study, we compared aortic annular areas measured by MDCT and 3DTEE in TAVR patients...

Dilatation of the ascending aorta (AA) is a common finding in patients with aortic valve disease. The clinical practice guidelines recommend replacing the AA whenever the diameter exceeds 45 mm. However, no consensus has been reached regarding the approach when the aorta is only moderately dilated. Although the risk in aorta replacement is generally low, it may be higher when associated with other complex surgical procedures or it is carried out in elderly patients or patients with significant comorbidity. This would justify the use of alternative surgical techniques, which reduce surgical risk and guarantee a durable correction of the aortic pathology...

Background Permanent pacemaker implantation after surgical aortic valve replacement depends on patient selection and risk factors for conduction disorders. We aimed to identify risk criteria and obtain a selected group comparable to patients assigned to transcatheter aortic valve implantation. Methods Isolated sutured aortic valve replacements in 994 patients treated from 2007 to 2015 were reviewed. Demographics, hospital stay, preexisting conduction disorders, surgical technique, and etiology in patients with and without permanent pacemaker implantation were compared...

OBJECTIVES: Minimal access mitral valve surgery (MVS) has already proved to be feasible and effective with low perioperative mortality and excellent long-term outcomes. However, experience in more complex valve diseases such as infective endocarditis (IE) still remains limited. The aim of this retrospective study was to evaluate early and long-term results of minimal access MVS for IE. METHODS: Data were entered into a dedicated database. Analysis was performed retrospectively for the 8-year period between January 2007 and April 2015...

OBJECTIVES: Determine the comparative impact of small prosthesis size on transcatheter and surgical aortic valve replacement (SAVR) outcomes. BACKGROUND: Patients with small aortic annuli tend to have worse postoperative outcomes and hemodynamics. We sought to describe surgical outcomes in patients with very small aortic annuli and then compare early hemodynamic and clinical outcomes in patients undergoing surgical or transcatheter aortic valve replacement (TAVR) with the smallest available valves to assist in optimal prosthesis selection for this challenging patient population...

BACKGROUND: Minimally invasive aortic valve replacement (MAVR) has demonstrated a benefit with respect to increased patient satisfaction due to minimised pain and earlier recovery. Sutureless valves may benefit MAVR and conventional aortic valve replacement (AVR) by reducing operative times and blood transfusion requirements. The Perceval valve (Sorin, Salluggia, Italy) is a self-expanding prosthesis made from bovine pericardium mounted in a nitinol stent, designed to simplify the implantation of an aortic valve...

Transcatheter aortic valve replacement (TAVR) has been validated as a new therapy for patients affected by severe symptomatic aortic stenosis who are not eligible for surgical intervention because of major contraindication or high operative risk. Patient selection for TAVR should be based not only on accurate assessment of aortic stenosis morphology, but also on several clinical and functional data. Multi-Imaging modalities should be preferred for assessing the anatomy and the dimensions of the aortic valve and annulus before TAVR...

BACKGROUND: The use of transcatheter aortic valve implantation (TAVI) following the introduction of Nitinol autoexpandable devices has spread rapidly during recent years. In addition, cardiac surgery has been revolutionized due to the use of Nitinol-based sutureless prostheses for aortic valve replacement (AVR). During the same period, however, permanent pacemaker (PPM) implantation has emerged as a frequent complication. The study aim was to identify the risk factors of PPM following the implantation of a Nitinol self-expanding prosthesis (for AVR or TAVI)...

BACKGROUND: The risk of patient-prosthesis mismatch drives most surgeons to select the largest bioprosthesis possible during aortic valve replacement, but interactions between the native aortic annulus and valve prosthesis remain poorly defined. We examined the hemodynamic and functional consequences of oversizing contemporary bioprostheses in an in vitro model. METHODS: Three sizes each (21, 23, and 25 mm) of 5 aortic bioprostheses (Magna, Edwards Lifesciences, Irvine, CA; Trifecta and Epic, St...

RATIONALE AND OBJECTIVES: Multimodality evaluation of the aortic annulus is generally advocated to plan for transcatheter aortic valve replacement (TAVR). We compared aortic annular measurements by cardiac computed tomography angiography (cCTA) to three-dimensional transesophageal echocardiography (3D-TEE), and also evaluated the use of semi-automated software for cCTA annular measurements. MATERIALS AND METHODS: A retrospective cohort of 74 patients underwent 3D-TEE and electrocardiogram-gated cCTA of the heart within 30 days for TAVR planning...
