Clinical outcome in nonagenarians undergoing transcatheter valve replacement.

Nonagenarians are mostly denied from different therapeutic strategies due to high preoperative risk. We present the results of nonagenarians with severe aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR).

Potential of transcatheter aortic valve replacement to improve post-procedure renal function.

Baseline comorbidities including renal dysfunction are frequently found in patients treated with transcatheter aortic valve replacement (TAVR) and may increase the risks of acute kidney injury (AKI), although some of them may actually improve renal function. We aimed to evaluate the potential of TAVR to acutely improve post-procedure renal function.

Sex-Specific Outcomes after Transcatheter Aortic Valve Replacement: A Review of the Literature.

Transcatheter aortic valve replacement (TAVR) is a safe and effective therapy for aortic valve replacement in patients ineligible for or at high risk for surgery. However, outcomes after TAVR based on an individual's sex remain to be fully elucidated. We searched PUBMED and EMBASE using the keywords: 'transcatheter aortic valve replacement', 'transcatheter aortic valve implantation', 'sex differences', 'gender', 'sex characteristics' and collected information on baseline features, procedural characteristics and post-procedural outcomes in women. In/exclusion resulted in 25 publications. Women had less pre-existing comorbidities than men. Most studies reported better survival in women (range of HR [95%CI] = 0.27 [0.09-0.84] to 0.91 [0.75-1.10]). At 30 days, women also had more vascular complications (6-20% vs. 2-14%) and higher bleeding rates (10-44% vs. 8-25%). Stroke rates were similar at 30 days (women: 1-7%; men: 1-5%). This literature review showed better survival in women than men after TAVR. However, women had more vascular complications and bleeding; stroke rates were similar. These findings may partly be explained by fewer baseline comorbidities in women. These results should be interpreted with caution as most measures only include unadjusted percentages.

Heart valve disesases : How sufficient is the knowledge of the German population?

To evaluate the awareness and knowledge of the German population regarding diseases in general, a survey of 1446 people aged 60 years or older was conducted in 14 German towns. The focus was on heart valve diseases with special emphasis on aortic valve stenosis (AS). While cancer was the disease that respondents were most concerned about (25.2%), only 3.3% were concerned about heart valve diseases. In this respect, the knowledge was broadly limited: only 7.4% of participants claimed to have some familiarity with heart valve diseases and only 12.5% could correctly describe the symptoms of AS. Even so, 35.0% of the participants could correctly name the number of human heart valves, 71.6% knew at least one therapy option for AS and 30.6% were familiar with transcatheter aortic valve implantation (TAVI). After providing a brief clarification of the prevalence, symptoms and course of AS, 45.6% of respondents were more concerned about the condition, 15.7% wanted to know more about the symptoms of AS and 4.7% even recognized the typical symptoms in themselves. Most of the participants would like to seek more information preferably in discussion with a specialist physician (77.2%), with their general practitioner (43.2%) or using the internet (29.7%). Despite its high prevalence, high morbidity and mortality, the vast majority of the German population were neither concerned nor fully aware of treatment options for AS. There is a strong case for public awareness campaigns that provide better knowledge of AS, and support check-ups that enable timely treatment and the avoidance of unnecessary hospitalization and death.

Hot topics in transcatheter aortic valve implantation.

Transcatheter aortic valve implantation - practice makes perfect.

Complicated transcatheter aortic-valve endocarditis with abscess and pseudoaneurysm: Value of the ECG-gated multidetector computed tomography angiography.

A 80-year-old man was admitted to catheterization room for an acute infero-lateral ST-elevation myocardial infarction (STEMI). Coronary angiography showed a thrombotic occlusion of the second left marginal branch, and normal other coronary arteries. The thrombo-embolic mechanism of the STEMI, and the infectious context in this patient who had had a transcatheter aortic valve implantation (TAVI) two months earlier, led us to suspect a bioprosthesis endocarditis. It was confirmed by transthoracic and transoesophageal echocardiography, which showed an aortic-mitral curtain abscess and aortic bioprosthesis vegetations, associated to Enterococcus faecalis bacteriemia. In order to specify the diagnosis, an ECG-gated multidetector CT angiography (MDCTA) had been performed. Additionally to echocardiographic findings, MDCTA showed a pseudo-aneurysm, sized 20 to 22mm, beginning from the outflow tract of the left ventricle to end on the antero-lateral face of the aorta. The patient was referred for emergency aortic bioprosthesis removal and replacement. Through this case, MDCTA showed its importance for the diagnosis and the prognostic evaluation of cardiac prosthesis endocarditis. MDCTA provided additional informations that echocardiography could not detect, because of artifacts caused by the prosthetic material and calcifications, frequent in elderly patients with comorbidities.

Pusher preventing maximum expansion of transfemoral transcatheter valves.

To report on 2 rare cases of balloon-expandable transfemoral transcatheter aortic valve implantation, where a trapped balloon led to complications requiring acute intervention. Both patients were elderly with increased risk profile and had been discussed by the heart team. After standard positioning of the valves using a transfemoral approach, retrieval of the pusher before deployment of the valve was missed. In 1 patient, rapid pacing was continued, the balloon deflated, the pusher pulled back and the balloon repositioned and reinflated. In the other patient, valve migration into the left ventricle occurred. A second valve was deployed. The embolized valve was then recovered from the ventricle via transapical access. Complications can occur in transcatheter aortic valve implantation, even when they are very rare. A predeployment check list, indicating key procedural steps on a standardized basis, should always be followed to easily prevent mishaps.

Treatment of a degenerated sutureless Sorin Perceval® valve using an Edwards SAPIEN 3.

Valve-in-valve implantation is an alternative to reoperation for patients with degenerated bioprostheses. This case report presents a 75-year-old woman presenting with worsening dyspnoea according New York Heart Association (NYHA) Class III after she had received a Sorin Perceval® S sutureless valve due to severe aortic valve stenosis 5 years ago. Echocardiography revealed a degenerated Perceval valve with severe valvular aortic regurgitation and stenosis. After exclusion of acute infective endocarditis, an Edwards SAPIEN 3 was implanted leading to an immediate haemodynamic improvement. A cerebral protection device caught a big embolized piece of material in the left carotid artery filter. The case demonstrates that not only suture-based stented and stentless bioprostheses can be treated by a valve-in-valve strategy, but it is also feasible to treat a failed sutureless Sorin Perceval using a balloon-expandable SAPIEN 3.

Sutureless aortic valve replacement versus transcatheter aortic valve implantation: a meta-analysis of comparative matched studies using propensity score matching.

The aim of this meta-analysis was to compare outcomes of patients undergoing transcatheter aortic valve implantation (TAVI) with those undergoing surgical aortic valve replacement using sutureless valves.

Transapical transcatheter aortic valve implantation in patients with a low ejection fraction.

It may be expected that patients with left ventricular dysfunction may be at greater risk of complications after transcatheter aortic valve implantation (TAVI) via transapical (TA) access compared with via transfemoral (TF) access. There is a lack of data comparing the outcomes of TAVI using TA and TF access in patients with a reduced left ventricular ejection fraction (EF).

A new technique to implant a transcatheter inflatable, fully repositionable prosthesis in aortic stenosis with severe asymmetric calcification.

In contrast to stented transcatheter aortic valves, the Direct Flow Medical (DFM) valve is a stentless bovine aortic bioprosthesis mounted in a non-metallic inflatable frame. Hence, severe asymmetric annular calcification may result in residually elevated transaortic pressure gradients after DFM implantation. We present a novel intraprocedural dilatation (IDIL) technique for successful implantation of the DFM valve in the presence of complex annular calcification.

Transinnominate approach for transcatheter aortic valve replacement: single-centre experience of minimally invasive alternative access.

Iliofemoral arteries have been the preferred access for transcatheter aortic valve replacement (TAVR). When these arteries are too small, calcified or tortuous, an alternative access must be considered. Transinnominate (TI) access is an extrathoracic approach that does not require manipulation of major neurovascular structures or the apex. The aim of this study is to evaluate the efficacy and safety of TI TAVR as an alternative access in patients with severe aortic stenosis not amenable to a transfemoral approach.

Shifting transcatheter aortic valve implantation to low-risk patients: a pilgrimage with no shortcuts.

Systematic review and meta-analysis to compare outcomes between intermediate- and high-risk patients undergoing transcatheter aortic valve implantation.

Recent studies have reported non-inferior outcomes for transcatheter aortic valve implantation (TAVI) compared with surgical aortic valve replacement (SAVR) in intermediate-risk patients. However, a comparison of outcomes among TAVI patients depending upon the surgical risk score has not been performed in a large study. Our aim was to compare the outcomes of TAVI in low-, intermediate-, and high-risk patients, to ascertain if the morbidity and mortality is related to the patient's risk profile or the procedure itself.

Double trouble for transcatheter aortic valve implantation: a patient with no vascular access and high-risk features for bilateral coronary obstruction.

Relative Survival After Transcatheter Aortic Valve Implantation: How Do Patients Undergoing Transcatheter Aortic Valve Implantation Fare Relative to the General Population?

Transcatheter aortic valve implantation (TAVI) is indicated for patients with aortic stenosis who are intermediate-high surgical risk. Although all-cause mortality rates after TAVI are established, survival attributable to the procedure is unclear because of competing causes of mortality. The aim was to report relative survival (RS) after TAVI, which accounts for background mortality risks in a matched general population.

Peripheral Artery Disease and Transcatheter Aortic Valve Replacement Outcomes: A Report From the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Therapy Registry.

Peripheral artery disease (PAD) is associated with increased cardiovascular mortality, and PAD risk factors overlap with those for aortic stenosis. The prevalence and outcomes associated with PAD in a population undergoing transcatheter aortic valve replacement (TAVR) are unknown.
