Cardiovascular surgery and cardiology, current status of two sister specialties in Spain: the CARDIOXCARDIO study.

In recent years, there has been a notable shift in cardiovascular clinical practice within cardiology and surgery. The CARDIOXCARDIO study aimed to identify professionals' opinions on working practices and relations between specialties. A survey was simultaneously sent to the 4442 members of the Spanish Society of Cardiovascular and Endovascular Surgery (SECCE) and the Spanish Society of Cardiology (SEC), yielding 385 valid responses. More than half (59%) of respondents were men, mostly specialists (7.3% residents), and 74.8% worked in the field of cardiology, predominantly in public centers (88.3%). Using a Likert scale ranging from 1 to 5 (worst to best), respondents rated relations between surgery and cardiology with an average of 3.57±0.9 points. Cardiologists rated surgeons with a mean score of 3.83±0.8, while surgeons gave cardiologists a mean score of 3,92±0.72. In addition, respondents provided numerous suggestions for improvement, which are discussed in detail, highlighting certain discrepancies in criteria between specialties. Implementing strategies based on the suggestions of professionals, together with a proactive approach to continuous improvement, could substantially enhance the quality of cardiovascular care in Spain.

Biological versus mechanical prostheses for aortic valve replacement.

OBJECTIVES: Long-term real-world outcomes are critical for informing decisions about biological (Bio) or mechanical (Mech) prostheses for aortic valve replacement, particularly in patients aged between 50 and 65 years. The objective was to compare long-term survival and major adverse cardiac and cardiovascular events (ie, stroke, reoperation, and major bleeding) within this population. METHODS: This was a multicenter observational study including all patients aged between 50 and 65 years who underwent an aortic valve replacement because of severe isolated aortic stenosis between the years 2000 and 2018. A total of 5215 patients from 27 Spanish hospitals were registered with a follow-up of 15 years. Multivariable analyses, including a 2:1 propensity score matching (1822 Mech and 911 Bio) and competing risks analyses were applied. RESULTS: Bio prostheses were implanted in 19% of patients (n = 992). No significant differences were observed between matched groups in long-term survival (hazard ratio [HR], 1.14; 95% confidence interval [CI], 0.88-1.47; P = .33). Stroke rates were higher for Mech prostheses, but not significant (HR, 0.72; 95% CI, 0.50-1.03; P = .07). Finally, higher rates of major bleeding were found in the Mech group (HR, 0.65; 95% CI, 0.49-0.87; P = .004), whereas reoperation was more frequent among the Bio group (HR, 3.04; 95% CI, 1.80-5.14; P < .001). Bio prostheses increased from 13% in the period from 2000 to 2008 to 24% in 2009 to 2018. CONCLUSIONS: Long-term survival was comparable among groups in patients between 50 and 65 years of age. Mech prostheses were associated with a higher risk of major bleeding, whereas Bio prostheses entailed higher reoperation rates. Bio prostheses seem a reasonable choice for patients between 50 and 65 years in Spain.

Quality of Life After Ministernotomy Versus Full Sternotomy Aortic Valve Replacement.

Quality of life and patient satisfaction after ministernotomy have never been compared to conventional full sternotomy in randomized trials. The QUALITY-AVR trial is a single-blind, single-center, independent, randomized clinical trial comparing ministernotomy to full sternotomy in patients with isolated severe aortic stenosis scheduled for elective aortic valve replacement. One hundred patients were randomized in a 1:1 computational fashion. The primary endpoint was a difference between intervention groups of ≥0.10 points in change from baseline quality of life Questionnaire EuroQOL-index, measured at 1, 6, or 12 months. Secondary endpoints were differences in change from other baseline EuroQOL-index utilities, cardiac surgery-specific satisfaction questionnaire (SATISCORE), a combined safety endpoint of 4 major adverse complications at 1 month (all-cause mortality, acute myocardial infarction, neurologic events, and acute renal failure), bleeding through drains within the first 24 hours, intubation time, and other minor endpoints. Clinical follow-up was scheduled at baseline, 1, 6, and 12 months after randomization. Change from baseline mean difference EQ-5D-index was +0.20 points (95% confidence interval 0.10-0.30, P < 0.001) and median difference +0.14 (95% confidence interval 0.06-0.22, P < 0.001), favoring the ministernotomy group at 1 month. Patient satisfaction was also better at 1 month (Satiscore 83 ± 9 vs 77 ± 13 points; P = 0.010). The ministernotomy group had significantly less bleeding in the first 24 hours (299 ± 140 vs 509 ± 251 mL, P = 0.001). Ministernotomy provides a faster recovery with improved quality of life and satisfaction at 1 month compared to full sternotomy.

Biological or mechanical prostheses for isolated aortic valve replacement in patients aged 50-65 years: the ANDALVALVE study.

OBJECTIVES: The decision about whether to use a biological or a mechanical prosthesis for aortic valve replacement remains controversial in patients between 50 and 65 years of age and has yet to be addressed in a Mediterranean population. This research aimed to analyse long-term survival and major morbidity rates (30-day mortality, stroke, any prosthetic reoperation and major bleeding) within this population. METHODS: Our multicentre observational retrospective study included all subjects aged 50-65 years who had a primary isolated aortic valve replacement due to severe aortic stenosis at 7 public hospitals from Andalusia (Spain) between 2000 and 2015. Concomitant surgery, reoperations and endocarditis were the exclusion criteria. A total of 1443 patients were enrolled in the study (272 with biological and 1171 with mechanical valves). Multivariate analyses including a 2:1 propensity score matching (506 mechanical and 257 biological prostheses) were conducted. RESULTS: Bioprostheses were implanted in 18.8% (n = 272): 35% were women; the mean EuroSCORE-I was 3%. The mean follow-up was 8.1 ± 4.9 years in a matched sample: 8.8 ± 4.9 years in those receiving a mechanical vs 7.1 ± 4.5 years in those receiving a biological prosthesis (P = 0.001). In the paired sample, the 15-year survival rate was 73% in those who had a biological vs 76% in those who had a mechanical valve [hazard ratio (HR) 0.80, 95% confidence interval (CI) 0.54-1.20; P = 0.159]. No significant differences were observed in patients ≥55 years old (74% of 15-year survival in both groups: HR 0.88, 95% CI 0.56-1.34; P = 0.527). A higher rate of major bleeding was found in patients with a mechanical prosthesis (P = 0.004), whereas reoperation was more frequent among those with a biological prosthesis (P = 0.01). CONCLUSIONS: Long-term survival was comparable in patients above 55 years of age. Mechanical prostheses were associated with more major bleeding and bioprostheses, with more reoperations. A bioprosthesis in patients above 55 years old is a reasonable choice. CLINICAL TRIAL REGISTRATION NUMBER: NCT03239509.

Quality of life, satisfaction and outcomes after ministernotomy versus full sternotomy isolated aortic valve replacement (QUALITY-AVR): study protocol for a randomised controlled trial.

BACKGROUND: During the last decade, the use of ministernotomy in cardiac surgery has increased. Quality of life and patient satisfaction after ministernotomy have never been compared to conventional full sternotomy in randomised trials. The aim of the study is to determine if this minimally invasive approach improves quality of life, satisfaction and clinical morbimortality outcomes. METHODS/DESIGN: The QUALITY-AVR trial is a single-blind, single-centre, independent, and pragmatic randomised clinical trial comparing ministernotomy ("J" shaped upper hemisternotomy toward right 4th intercostal space) to full sternotomy in patients with isolated severe aortic stenosis scheduled for elective aortic valve replacement. One hundred patients will be randomised in a 1:1 computational fashion. Sample size was determined for the primary end point with alpha error of 0.05 and with power of 90% in detecting differences between intervention groups of ≥ 0.10 points in change from baseline quality of life Questionnaire EuroQOL-index (EQ-5D-5 L®), measured at 1, 6 or 12 months. Secondary endpoints are: the differences in change from other baseline EQ-5D-5 L® utilities (visual analogue scale, Health Index and Severity Index), cardiac surgery specific satisfaction questionnaire (SATISCORE®), a combined safety endpoint of four major adverse complications at 1 month (all-cause mortality, acute myocardial infarction, neurologic events and acute renal failure), bleeding through drains within the first 24 h, intubation time, postoperative hospital and intensive care unit length of stay, transfusion needs during the first 72 h and 1-year survival rates. Clinical follow up is scheduled at baseline, 1, 6, and 12 months after randomization. All clinical outcomes are recorded following the Valve Academic Research Consortium 2 criteria. DISCUSSION: The QUALITY-AVR trial aims to test the hypothesis that ministernotomy improves quality of life, satisfaction and clinical outcomes in patients referred for isolated aortic valve replacement. Statistically significant differences favouring ministernotomy could modify the surgical "gold standard" for aortic stenosis surgery, and subsequently the need to change the control group in transcatheter aortic valve implantation trials. Recruitment started on 18 March 2016. In November 2017, 75 patients were enrolled. TRIAL REGISTRATION: ClinicalTrials.gov , NCT02726087 . Registered on 13 March 2016.

Primary inferior vena cava leiomyosarcoma: reconstruction is not mandatory.

Computed tomography in an 81-year-old woman revealed obstruction of the inferior vena cava by a large primary vascular leiomyosarcoma, and involvement of the right renal vein. She underwent successful en-bloc resection of the tumor, right kidney, hepatic segments IV and VI, and inferior vena cava, without caval reconstruction. A renal vein-to-remaining infrahepatic inferior vena cava saphenous vein graft bypass was performed for left renal venous drainage. The need for vascular reconstruction is not always mandatory.

Transapical aortic valve implantation in bicuspid aortic valves: must be an absolute contraindication?

Transcatheter Aortic Valve Implantation (TAVI) is a new therapeutic option for patients with severe aortic stenosis with unacceptable surgical risk for conventional aortic valve surgery. A Bicuspid Aortic Valve (BAV) is the most common congenital cardiac disorder (1% of the population) and currently is considered exclusion criteria for TAVI, because it predicts an increased risk of adverse aortic events as incomplete sealing, severe paravalvular regurgitation, or dislocation due to more frequent elliptic shape and asymmetric calcifications in BAV annulus. Only few cases have been published in recent literature, so in this case report we illustrate our experience and management of TAVI in a BAV, with excellent outcomes and no late complications at 1 year follow-up. We believe that currently the presence of a BAV might not be considered an absolute contraindication for TAVI, because although there is no sufficient data for assess the safety or efficacy of TAVI in BAV, this case report shows that it could be performed safely in selected patients with unacceptable surgical risk after an extensive preoperative evaluation, avoiding this procedure in patients with bad prognostic factors as huge and heavy calcifications, asymmetric valves, elliptic annulus or small distance from leaflets to coronary ostia. Each case must be individualized, being alert at follow-up because the risk of late complications.

Mega-aorta syndrome development in giant cell arteritis. A same entity?

Giant cell arteritis (GCA) is the most common form of large vessel arteritis. GCA typically involves the branches of the external carotid artery, but is the leading cause of inflammatory aortitis. However, involvement of the aorta often goes undetected. We present a case of an 81-year-old man, with headache and intense chest pain, who was previously given a diagnosis of GCA with a temporal artery biopsy 6 years ago. Owing to the suspicion of acute aortic syndrome, an emergent computed tomography (CT) was performed. CT showed the development of mega-aorta syndrome, with a diameter of 75.2 mm in the ascending aorta, 61.8 mm in the aortic arch, 76.1 mm in the descending thoracic aorta, and 45.1 mm in the abdominal aorta, presenting a chronic type B aortic dissection. Although there are reported cases secondary to Takayasu arteritis, this is the first case reported in the literature of mega-aorta syndrome associated with GCA in a patient previously diagnosed using temporal artery biopsy.

Management of aortic valve dysfunction after transapical approach using the technique "valve after valve".

We report a case of a 77-year-old patient with severe aortic stenosis who underwent transapical aortic valve implantation with a 23-mm Edwards Sapien valve (Edwards Lifesciences Inc, Irvine CA). This procedure was complicated with the occurrence of an acute regurgitation due to entrapment of one of the leaflets that was successfully managed by valve after valve technique.

Spontaneous closure of pseudoaneurysm after transapical aortic valve implantation.

Transcatheter aortic valve implantation by an apical approach has been developed as an alternative to conventional aortic valve replacement. Complications with these relatively new procedures are being reported. We report a case of transapical transcatheter aortic valve implantation, in which a pseudoaneurysm at the apex of the left ventricle as a complication of the procedure developed in the patient and was treated without surgery. The defect spontaneously closed.
