A 63 year old patient underwent uncomplicated valve replacement with the Edwards Intuity valve. 2 months post operation, the patient had progredient dyspnea. Echocardiography showed a dislocated aortic valve reaching into the left ventricular outflow tract, impairing the anterior mitral valve leaflet. Both v...

Self-expanding transcatheter aortic valve implantation for degenerated Mitroflow bioprosthesis: Early outcomes.

The aim of this study was to assess the safety and effectiveness of valve in valve (VIV) TAVI with the autoexpandable valve, specifically in patients with failed Mitroflow (MF) bioprosthetic aortic valves.

Description of the aortic root anatomy in relation to transcatheter aortic valve implantation.

Transcatheter aortic valve implantation (TAVI) has emerged as a less invasive treatment than surgical aortic valve replacement in patients with aortic stenosis. Understanding the anatomy of aortic valve complex may help in optimal positioning of prosthetic valve and circumvent complications that can arise during its implantation.

Meta-analysis of Valve-in-Valve Transcatheter versus Redo Surgical Aortic Valve Replacement.

 The objective of this study was to determine whether valve-in-valve transcatheter aortic valve implantation (VIV-TAVI) is associated with better survival than redo surgical aortic valve replacement (SAVR) in patients with degenerated aortic valve bioprostheses, and we performed a meta-analysis of comparative studies.

Surgical aortic valve replacement for valve-in-valve trans-catheter aortic valve dysfunction in the patient with a small aortic annulus.

Urgent transcatheter aortic valve replacement for severe acute aortic regurgitation following open mitral valve surgery.

Transcatheter aortic valve replacement (TAVR) is not currently approved for pure native valve aortic incompetence, and is typically performed on a compassionate basis in selected patients who are at high risk for conventional surgery. We describe the first use of TAVR to treat iatrogenic severe acute pure aortic incompetence following mitral valve surgery. A 71-year-old gentleman developed life-threatening acute aortic regurgitation (AR) within hours of a very challenging fifth open heart mitral valve repla...

Thrombocytopenia After Transcatheter Valve-in-Valve Implantation: Prognostic Marker or Mere Finding?

To analyze the behavior of platelets after transcatheter valve-in-valve implantation for the treatment of degenerated bioprosthesis and how they correlate with adverse events upon follow-up.

Valve-sparing aortic root replacement combined with bicuspidization for a quadricuspid aortic valve.

Quadricuspid aortic valves are rare congenital malformations. Although aortic valve replacement is the first-choice treatment in most cases, aortic valve repair using a tricuspidization procedure has been reported. Herein, we report the case of a patient with a quadricuspid aortic valve associated with aortic insufficiency that we successfully repaired with aortic valve-sparing root replacement and bicuspidization.

Severe structural deterioration of small aortic bioprostheses treated with valve-in-valve transcatheter aortic valve implantation.

The aim of this study was to evaluate outcomes of valve-in-valve transcatheter aortic valve implantation (VIV-TAVI) in patients with degenerated small bioprostheses.

Thromboembolic acute myocardial infarction after aortic valve replacement using the Freestyle stentless aortic bioprosthesis with subcoronary valve replacement.

A 70-year-old woman with substernal chest pain lasting 2.5 h presented to the emergency department of our hospital. She had a history of aortic valve replacement with the Freestyle stentless aortic bioprosthesis for severe aortic regurgitation 7 years ago. The initial electrocardiogram showed sinus rhythm at a rate of 71 bpm with ST-segment slight elevation in leads II, III and aVF. She was diagnosed as having acute coronary syndrome and was referred for an urgent catheterization. Urgent coronary angiogra...

Development and Results of Transcatheter and Surgical Aortic Valve Replacement in Germany 2014 and 2015.

 Treatment of aortic valve stenosis has been changing since the introduction of transcatheter aortic valve replacement (TAVR). The present study investigates the treatment of aortic valve stenosis in a real-world population 2014 and 2015 in Germany.

Predicting the future of TAVR: an obituary to open aortic valve replacement?

Transcatheter aortic valve replacement (TAVR) has become the cornerstone for aortic valve intervention since the first implantation in 2002. Recent advances with novel devices and introduction into lower risk cohorts have been successful. In this review, we discuss the ongoing limitations to transcatheter aortic valve therapy and whether it will replace surgical aortic valve replacement in the foreseeable future.

Excessive pannus overgrowth on the aortic side of Trifecta valve determining severe regurgitation.

Structural valve deterioration represents the most important concern regarding the implantation of a biological heart valve in young patients. Several strategies have been proposed to improve prosthesis design in order to optimize performance and durability. Here we describe an early and specific mode for valve degeneration of prosthesis with outwards mounted pericardial leaflets due to pannus overgrowth on the aortic side. This led to leaflet retraction in two consecutive cases four and six years after the...

Reconstruction of regurgitant bicuspid aortic valve (Sievers type 1, L/R, I) with raphe resection and concomitant pericardial patch-augmentation: A standardized approach.

A major limitation of the more widespread application of aortic valve reconstruction is the lack of a common framework for valve assessment that could  be used to guide a standardized approach to aortic valve repair, similar to that used in reconstructive mitral valve surgery. Most patients with a regurgitant aortic valve are young and possess a specific subtype of a bicuspid aortic valve according to the Sievers classifications system. This video tutorial presents the technical aspects of a standardized ...

Biomarkers of aortic bioprosthetic valve structural degeneration.

Bioprosthetic valves are now used for the majority of surgical aortic valve replacements and for all transcatheter aortic valve replacements. However, bioprostheses are subject to structural valve deterioration (SVD) and have, therefore limited durability.

Improvement in the Assessment of Aortic Valve and Aortic Aneurysm Repair by 3-Dimensional Echocardiography.

Reconstructive surgery of the aortic valve is being increasingly used in patients with aortic regurgitation and/or aortic aneurysm. Its success depends on restoring normal aortic valve and root form. Echocardiography is the most reliable and precise imaging technique because it defines abnormal morphology and function, essential for selecting appropriate substrates and guiding the surgical strategy. Despite technical advances in echocardiography, aortic valve and aortic root morphology and function are stil...

Ten-year follow-up of unreplaced Valsalva sinuses after aortic valve replacement in bicuspid aortic valve disease.

Aortopathy is common in patients with bicuspid aortic valve (BAV).

Outcomes of direct transcatheter aortic valve replacement without balloon aortic valvuloplasty using a new generation valve.

We investigated the outcomes of patients who underwent Transcatheter Aortic Valve Replacement (TAVR) with and without Balloon Aortic Valvuloplasty (BAV) using the SAPIEN 3 (S3) valve.

Commissural Alignment of Bioprosthetic Aortic Valve and Native Aortic Valve Following Surgical and Transcatheter Aortic Valve Replacement and its Impact on Valvular Function and Coronary Filling.

The aim of this study was to assess the commissural alignment between bioprosthetic and native aortic valve leaflets following surgical aortic valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR) and to investigate its impact on valvular function and coronary filling.

Sutureless Valve Replacement Through a Right Anterior Mini-thoracotomy In Elderly Patients With Stenotic Bicuspid Aortic Valve.

Several indications for sutureless aortic valve replacement (SU-AVR) have been a matter of debate. We evaluated our experience with Perceval-S (LivaNova group, Saluggia, Italy) SU-AVR in patients with severe aortic stenosis (AS) involving bicuspid aortic valve (BAV), even though presence of BAV is still considered to be a contraindication for sutureless valves.

Clinical and Echocardiographic Outcomes after Aortic Valve Repair in Patients with Bicuspid or Unicuspid Aortic Valve.

Unicuspid and bicuspid aortic valve (BAV) are congenital cardiac anomalies associated with valvular dysfunction and aortopathies occurring at a young age.

Transcatheter Aortic Valve Replacement for Pure Native Aortic Valve Regurgitation: A Systematic Review.

Transcatheter aortic valve replacement (TAVR) is a recent and an effective treatment option for high- or extreme-surgical-risk patients with symptomatic severe aortic stenosis. However, pure severe native aortic valve regurgitation (NAVR) without aortic stenosis remains a contraindication to TAVR. The aim of our systemic review analysis was to evaluate TAVR in patients with pure NAVR.

Transcatheter treatment of pure aortic regurgitation in a horizontal aorta complicated by valve embolization and aortic dissection.

A 83-year-old female with severe aortic regurgitation (AR) and an horizontal ascending aorta was scheduled for a transcatheter aortic valve replacement. After the complete deployment, a Portico 29 mm valve embolized in the ascending aorta due to the unfavorable anatomy of the anchoring zone. A second Portico 29 mm was successfully implanted using the embolized valve for superior anchoring. The patient died 7 days after the procedure due to a retrograde aortic dissection. This case shows a rare but pos...
