BACKGROUND: Transcarotid access is an alternative route for transcutaneous aortic valve implantation (TAVI) in patients with impossible transfemoral access. AIMS: We evaluated the safety, effectiveness and early and late clinical outcomes of CoreValve(®) implantation via the common carotid artery. METHODS: Eighteen patients (10 men, 8 women; mean age 84±5 years) at high surgical risk (mean EuroSCORE II 16±13%) with significant peripheral artery disease underwent TAVI via common carotid artery access under general anaesthesia...

The VARC (Valve Academic Research Consortium) for transcatheter aortic valve replacement set the standard for selecting appropriate clinical endpoints reflecting safety and effectiveness of transcatheter devices, and defining single and composite clinical endpoints for clinical trials. No such standardization exists for circumferentially sutured surgical valve paravalvular leak (PVL) closure. This document seeks to provide core principles, appropriate clinical endpoints, and endpoint definitions to be used in clinical trials of PVL closure devices...

OBJECTIVES: Severe calcification in the mitral valve annulus is a challenging problem during mitral valve surgery. We describe our experience with mitral valve replacement in severely calcified mitral valve without decalcification of the annulus. METHODS: Between April 2001 and July 2011, 61 patients underwent mitral valve replacement with severe mitral annulus calcification without decalcification of the annulus. This retrospective study was performed to assess the surgical and the long-term postoperative outcomes in this group...

OBJECTIVES: To evaluate the feasibility, safety, and efficacy of direct transcatheter aortic valve replacement (TAVR), that is, TAVR without balloon predilation (BPD), by performing a systematic review and meta-analysis of available evidence. BACKGROUND: Avoiding BPD during TAVR was shown to be feasible in previous studies but the risks and benefits of this technique are unknown owing to the limited number of patients included in these studies. METHODS: We performed a systematic search for studies comparing direct TAVR vs TAVR performed with BPD...

We report the case of severe aortic regurgitation 8 months after implantation of a 25-mm sutureless pericardial aortic valve prosthesis. On echocardiography, the regurgitation was suspected to be paravalvular. The sutureless prosthesis had been implanted using an automatic knot fastener device, which renders the suture tails less pliable because of the metal clip that is crimped around the suture.The patient was reoperated, a paravalvular leak was not observed. The sutureless prosthesis was explanted and a conventional biologic valve prosthesis was implanted instead...

Pulmonary valve replacement (PVR) is the most common adult congenital cardiac operation performed. Valve degeneration leading to prosthetic stenosis and/or regurgitation is a long-term risk in this population and may be associated with paravalvular leak (PVL). Complications involving the proximal pulmonary artery, including dissection, are less clearly defined. Herein, we report the case of a 30-year-old patient with a history of multiple pulmonary valve interventions secondary to congenital pulmonic stenosis, who developed dehiscence of a bioprosthetic PVR associated with significant paravalvular leak (PVL) and further complicated by a focal dissection of the proximal pulmonary artery...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valve stenosis (AS) is being increasingly performed. OBJECTIVES: From the Bicuspid AS TAVR multicenter registry, the procedural and clinical outcomes in patients with bicuspid versus tricuspid AS were compared. METHODS: Outcomes of 561 patients with bicuspid AS and 4,546 patients with tricuspid AS were compared after propensity-score matching assembling 546 pairs of patients with similar baseline characteristics...

OBJECTIVES: To investigate short- and long-term outcomes of a conservative decalcification approach in mitral valve replacement (MVR) surgery in the presence of mitral annulus calcification (MAC). METHODS: Of the 1038 patients who underwent MVR, 133 (13%) had significant MAC with at least 30% of the annular circumference heavily calcified. In most patients, the surgical approach to MAC included conservative decalcification, supra-annular prosthesis implantation and insertion of a pericardial patch between the MV annulus and the prosthesis...

The development of paravalvular leak (PVL) following surgical replacement of an aortic or mitral valve is an uncommon complication with significant morbidity and mortality. Surgical or percutaneous repair of PVL can be technically challenging. We describe the application of intracardiac echocardiography guided 3-dimensional electroanatomic mapping to facilitate PVL closure in a symptomatic patient with a previously placed bioprosthetic mitral valve. © 2017 Wiley Periodicals, Inc.

OBJECTIVES: The aim of this study was to compare outcomes of transcatheter intervention (TI) versus surgical intervention (SI) for paravalvular leak (PVL). BACKGROUND: Data comparing the treatment of PVL with TI and SI are limited. METHODS: A retrospective cohort study was conducted comparing baseline characteristics, procedural details, and 1-year survival in consecutive patients who underwent TI or SI for moderate or greater PVL from 2007 to 2016...

Significant periprosthetic aortic regurgitation after transcatheter aortic valve implantation has become a major concern of this technique given its association with impaired survival. We report the successful closure of such defect using a vascular occlusion device with the creation of an arterio-arterial loop to gain enough support to advance the delivery sheath into de the left ventricle.

Dissection of the interventricular septum (IVS) is an extremely rare entity. An institutional echocardiographic database was retrospectively reviewed; 13 patients with a diagnosis of IVS dissection were found and confirmed by cardiac surgery. The purposes of the study were: to determine the value of transthoracic echocardiography (TTE) in establishing the diagnosis of IVS dissection, and to detail the TTE features of IVS dissection.Thirteen patients with IVS dissection diagnosed by TTE, 8 males and 5 females were taken from 789,114 TTE studies performed between 1985 and 2014...

BACKGROUND: To investigate the individual sequential hemodynamic changes after transcatheter aortic valve implantation (TAVI), especially for patients with bicuspid aortic valve (BAV), in comparison with tricuspid aortic valve (TAV). METHODS: The study population comprised 85 patients with severe aortic stenosis who underwent TAVI for BAV (n = 49) or TAV (n = 36) with at least two serial echocardiographic follow-ups. Doppler echocardiography was scheduled to be performed at discharge and 1, 3, 6 months and 1 year after the procedure...

An 87-year-old woman with severe aortic stenosis underwent a transfemoral transcatheter aortic valve replacement (TAVR). Intraoperative transesophageal echocardiography demonstrated a well-seated valve with no paravalvular leak; however, a new acute type B aortic dissection was identified. Endografts were delivered through the TAVR sheath and deployed, effectively treating the dissection. The patient did well postoperatively, with imaging at 2 years demonstrating a well-functioning aortic valve and no migration or endoleak of the thoracic endografts...

OBJECTIVE: The aim of this study was to investigate interactions among pre-procedural aortic regurgitation (AR), post-procedural paravalvular leak (PVL) and long-term clinical outcomes. METHODS AND RESULTS: We analyzed data prospectively collected in the Italian Transcatheter balloon-Expandable Registry (ITER) on aortic stenosis (AS) patients. The degree of pre-procedural AR and post-procedural PVL was stratified as: absent/trivial, mild, and moderate/severe. VARC definitions were applied to outcomes...

BACKGROUND: Percutaneous paravalvular leak (PVL) closure is an alternative treatment option for severely symptomatic, high-surgical risk patients with PVL. Some patients require multiple percutaneous PVL closure procedures. However, the procedural characteristics and success rate of re-do PVL closure have not been well studied. AIMS: The aim of this study is to investigate the indications, procedural characteristics, technical success rate, and 30-day major adverse cardiovascular events (MACE) in patients who underwent re-do PVL closure...
