Since the 1960s when the first aortic surgical aortic valve replacement (SAVR) was performed, continuous growth in the field of valvular technology has occurred. Although SAVR remains a lifesaving procedure, minimally invasive transcatheter aortic valve replacement has revolutionized and expanded aortic valve replacement to patients who were not previously SAVR candidates, increasing their quality of life and survival. Since its introduction in the United States in 2011, the technology and practice have rapidly expanded...

The main limitation of bioprosthetic valves is their limited durability, which exposes the patient to the risk of aortic valve reintervention. Transcatheter aortic valve implantation (TAVI) is considered a reasonable alternative to surgical aortic valve replacement (SAVR) in patients with intermediate or high surgical risk. TAVI is now rapidly expanding towards the lower risk populations. Although the results of midterm durability of the transcatheter bioprostheses are encouraging, their long-term durability remains largely unknown...

After 8 years of practice and over 400 operated patients, we present a technique of minimally invasive aortic valve replacement that can be used by all surgeons on many patients. The access to the aorta is via the 2nd or 3rd right anterior intercostal space. Cardiopulmonary bypass is provided using the femoral artery and vein. The aorta is clamped directly. One shot of Custodiol (EUSA Pharma, Limonest, France) is the most commonly used cardioplegia. Aortic valve replacement is performed in the regular way...

BACKGROUND: Expandable, rapid deployment aortic valves may interfere with the cardiac conduction system, which can lead to permanent pacemaker implantation (PPI). We sought to characterize PPI following rapid deployment aortic valve replacement (RDAVR) with the EDWARDS INTUITY valve system and investigate associated factors. METHODS: We analyzed 708 patients from 29 centers in the TRANSFORM trial undergoing RDAVR ± CABG without pre-existing pacemakers. Intrinsic conduction status was recorded as well as PPI incidence through one year...

INTRODUCTION: Aortic valve stenosis (AS) is the most common valvular pathology in the elderly. Surgical aortic valve replacement (AVR) remains the gold-standard of treatment for AS. However, emerging transcatheter aortic valve replacement (TAVR) has become an increasing alternative to surgery. In a recent survey from the European Society of Cardiology, 9,4% of the physicians stated that age was the main reason to propose for a TAVR instead of surgery. METHODS: We performed a single-center retrospective study including 353 patients (149 patients over 80 years-old, compared to 204 patients between 60-69 years-old) consecutively submitted to AVR between January 1, 2013, and December 31, 2016, to compare the results of both groups in AVR surgery and how we can improve surgery outcome in older patients...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is a minimally invasive approach to aortic valve replacement. However, critical cardiovascular collapse can occur during the procedure for various reasons. CASE PRESENTATION: A 90-year-old man with severe aortic stenosis and left circumflex artery stenosis developed acute torrential mitral regurgitation (MR) during TAVR. The valve deployment process induced left ventricular dyssynchrony due to left bundle-branch block and myocardial ischemia in the left circumflex artery region with torrential MR...

BACKGROUND: Surgical aortic valve replacement using conventional biological valves (CBVs) is the standard of care for treatment of old patients with aortic valve disease. Recently, rapid deployment valves (RDVs) have been introduced. OBJECTIVES: The purpose of this study was to report the nationwide German experience concerning RDVs for treatment of aortic valve stenosis and provide a head-to-head comparison with CBVs. METHODS: A total of 22,062 patients who underwent isolated surgical aortic valve replacement using CBV or RDV between 2011 and 2015 were enrolled into the German Aortic Valve Registry...

Transcatheter aortic valve implantation (TAVI) is an effective and less invasive treatment for the increasing population of individuals with severe aortic stenosis (AS). Echocardiography is crucial in the assessment of AS patients from pre- to post-procedure. Transthoracic echocardiography (TTE) may be used to assess patient suitability for TAVI, as well as evaluate the severity of AS, the aortic valve complex, aortic valve morphology, mitral regurgitation (MR), and left ventricular function. Transesophageal echocardiography (TEE) is usually used as an intra-procedural monitoring tool to provide feedback during the procedure, to assess prosthetic valve function, and to detect complications rapidly before and after balloon aortic valvuloplasty (BAV) or transcatheter heart valve (THV) deployment...

OBJECTIVES: Rapid-deployment aortic valve replacement (RD-AVR) potentially reduces procedure times providing excellent haemodynamic results compared to standard tissue aortic valve replacement. However, concerns have been raised regarding higher rates of postoperative pacemaker (PPM) requirement compared to standard aortic valve replacement. In this study, we sought to determine the PPM rate and its potential risk factors in RD-AVR patients. METHODS: Between 2011 and 2017, 193 patients underwent RD-AVR...

We herein report anesthetic management during aortic valve replacement for aortic valve regurgitation in a patient with adult mucopolysaccharidosis type II (MPS type 2) (Hunter syndrome). This disorder is rare and related to the accumulation of a mucopolysaccharide in lysosomes. It affects various organs, including the airways, heart, and central nerves. In children with MPS type 2, the risk of airway obstruction during anesthesia/sedation is high, and the degree of difficulty increases with aging. The patient described herein was a 33-year-old male without mental retardation...

Bioprosthetic aortic valves have been used with increasing frequency over the past two decades, often in relatively young patients who may eventually require aortic valve re-operations due to degeneration of the bioprosthesis. Growing experience with minimally invasive aortic valve replacement has prompted surgeons to use minimally invasive approaches also with redo operations for replacement of the aortic valve.  This tutorial describes the operative steps for a minimally invasive redo replacement of the aortic valve through an upper ministernotomy...
