Left ventricular outflow tract obstruction after transcatheter mitral valve replacement: a case report with a multifaceted approach.

An 83-year-old woman was admitted to our center because of heart failure. Transthoracic echocardiography revealed severe mitral annular calcification resulting in a double mitral valve lesion. After discussion by the heart team, transcatheter mitral valve replacement with Tendyne (Abbott Structural, Santa Clara, CA, USA) was performed.

Mid-term assessment of structural valve deterioration of perceval S sutureless prosthesis using the last European consensus definition.

Objectives: Durability of sutureless aortic bioprosthetic valves remains a major issue. The aim of this study was to assess structural valve deterioration (SVD) and bioprosthetic valve failure (BVF) of the Perceval bioprosthesis using the new proposed standardized definitions.

Methods: All patients who underwent aortic valve replacement with sutureless Perceval S prostheses up to September 2016 were included.

Surgical technique modifies the postoperative atrioventricular block rate in sutureless prostheses.

Background: The main objective was to analyse the impact of the modification of the Perceval S implantation technique on the prevalence of postoperative atrioventricular block, which requires a permanent pacemaker, in our aortic valve replacement series. In addition, we attempted to identify those risk factors that are related to the appearance of this complication.

Methods: Five hundred and seventy-two valve replacements were carried out with PERCEVAL S in our centre up to July 2018.

Postoperative Plasma Mitochondrial DNA and Cytokine Profiles of Elderly Patients Undergoing Minimally Invasive Aortic Valve Replacement.

Introduction: Mitochondrial DNA (mtDNA) is gaining increasing interest as a marker of cellular damage and could also act as an inflammatory mediator in cardiopulmonary bypass induced postoperative inflammatory response. Although minimally invasive heart valve surgery reportedly reduces inflammation, the mtDNA and cytokine profile in this context remains unclear.

Materials And Methods: Here, we report a prospective series of 40 elderly patients with aortic stenosis who underwent bioprosthetic aortic valve replacement (AVR) through upper ministernotomy with either a sutureless ( = 20) or a conventional ( = 20) valve.

Circulating Galectin-3 Following Heart Transplant: Long-term Dynamics and Prognostic Value.

Introduction And Objectives: Circulating galectin-3 (Gal-3) is elevated and significantly correlates with all-cause and cardiovascular mortality in patients with heart failure. However, the relationship between serum Gal-3 and heart transplant (HT) outcomes is unclear. The aim of this study was to describe the longitudinal trend and prognostic value of Gal-3 levels after HT.

The "Auto-sliding Graft" Aortic Wrapping Technique.

We describe the "auto-sliding graft" technique, a different anastomotic option for reconstructive prosthetic procedures on the ascending aorta especially in patients at risk of circulatory arrest with mild aortic dilatation. This simple technique provides not only an important hemostatic reinforcement for the distal aortic graft anastomosis but also a protective effect on the native ascending aorta beyond the suture line.

Perceval Less Invasive Aortic Replacement Register: multicentric Spanish experience with the Perceval S bioprosthesis in moderate-high-risk aortic surgery.

Objectives: The development of new percutaneous and surgical techniques has reduced the risk associated with aortic valve replacement procedures. We present the results of a Spanish register after initiating a programme for sutureless prostheses in moderate-high-risk patients.

Methods: This prospective multicentre study was carried out from November 2013 to November 2016.

Toxoplasma Gondii Serostatus in Heart Transplant Recipients: Is It an Independent Prognostic Factor?

Introduction And Objectives: To assess the potential association between recipient Toxoplasma gondii serostatus and outcomes after heart transplant (HT).

Methods: We conducted a retrospective single-center study of 657 HT recipients from 1991 to 2015. Survival and the incidence of adverse clinical events of T.

Long-Term Outcomes and Durability of the Mitroflow Aortic Bioprosthesis.

Background: This study aims to determine the incidence and causes of structural valve deterioration (SVD) among all models of Mitroflow bioprostheses (A12/LX/DL), as well as to define their long-term clinical and hemodynamic performance.

Methods And Results: We retrospectively reviewed a series of 1023 patients who underwent aortic valve replacement with Mitroflow bioprostheses between 2001 and 2014. A small aortic root was found in 22.

Spontaneous fracture and embolization of an inferior vena cava cannula: is it possible?

We present a case of spontaneous fracture and embolization of the distal part of a cannula into the left inferior lobar artery. The embolized fragment was captured with an angioplasty balloon and extracted through the right atrium appendage. No adverse event related to the embolization was observed and the patient was discharged with no sequelae.

The CarboMedics supra-annular Top Hat valve improves long-term left ventricular mass regression.

Objective: The present study aimed to identify potential differences in hemodynamic performance between the supra-annular CarboMedics Top Hat valve and the intra-annular CarboMedics standard valve in terms of the long-term left ventricular mass reduction and transvalvular gradients.

Methods: We retrospectively reviewed a series of 186 consecutive patients who had undergone aortic valve replacement with a small size mechanical prosthesis at our institution from 2003 to 2013, receiving either a CarboMedics Top Hat valve (53 patients, valve size, 21 mm in 52.8% and 23 mm in 47.

[Mitral valve repair using polytetrafluoroethylene neochordae: short-term outcomes].

In recent years, mitral valve repair using polytetrafluoroethylene (PTFE) neochordae has been shown to be an effective technique for correcting valve prolapse due to chordal rupture or elongation. In this study, we evaluated our experience using this technique in a group of 21 patients. The median (range) follow-up period was 9 (1-26) months.
