RESUMO

According to the results of modern researchers, the main techniques used in congenital pathology of the aortic valve in children include balloon catheter dilatation of the aortic valve, surgical valvuloplasty, the Ross procedure and replacement of the aortic valve with a mechanical prosthesis. Many surgeons point out that these techniques in congenital pathology of the aortic valve yield suboptimal results. This is often due to the lack of a clear-cut definition between surgeons as to what operation should be performed in a particular age group. According to the reports of the majority of researchers, biological prostheses undergo early degeneration and structural changes in paediatric cardiac surgery and yield the worst results. Comparing the main techniques, optimal haemodynamics is observed after the Ross procedure. A disadvantage of this operation is the necessity of repeat intervention on the right ventricular outflow tract, which is required in 20 to 40%. Concomitant surgery of the mitral valve and/or aortic arch during the Ross procedure significantly increases the lethality and the risk of postoperative complications. Compared with an adult cohort of patients, children after prosthetic repair of the aortic valve using a mechanical prosthesis are more often found to have postoperative complications and a higher mortality rate. Yet another problem encountered in paediatric valve surgery is the unavailability of commercial prostheses sized ?19 mm. The duration of the intraoperative parameters for reconstructions of the aortic valve, the Ross procedure, and replacement of the aortic valve by the results of many studies averagely amounts to 74±34 min, 100±56 min, and 129±71 min, respectively. Yet another method which can be used for neocuspidization of the aortic valve in reconstructive surgery of the aortic root in paediatric patients is the use of glutaraldehyde-treated autologous pericardium. In our opinion, given the simplicity of the procedure, duration of the intraoperative parameters, and acceptable initial results reported by some researchers, the Ozaki procedure may be performed in children.

RESUMO

Postoperative coronary artery complications after Bentall procedures are well recognised but are rare and potentially fatal. There have been only five cases documenting percutaneous coronary intervention (PCI) for right coronary artery (RCA) involvements after button Bentall procedures. We describe a case of postoperative silent myocardial ischaemia in a 72-year-old man who underwent the button Bentall procedure for a right sinus of Valsalva aneurysm. On postoperative day 15, an RCA complication was incidentally detected by follow-up multidetector CT. Coronary angiography showed proximal RCA kinking, which was not an anastomosis but a native coronary artery. The patient underwent a successful PCI with drug-eluting stent implantation. We reviewed six cases consisting of this case and five previous cases treated with PCI. These cases enhance the recognition of potential RCA complications after the button Bentall procedure.

RESUMO

OBJECTIVE: The probability of aortic complications in patients with bicuspid aortic valve is higher in association with aortic regurgitation (AR) compared with aortic stenosis (AS) or normally functioning valves. The objective of this study was to determine whether this is related to the specific characteristics of aneurysmatic dilatation that includes AR or whether AR itself has a negative impact on the aortic wall, independent of aneurysmatic dilatation. Approach and Results: Nondilated aortic specimens were harvested intraoperatively from individuals with tricuspid aortic valves and either AS (n=10) or AR (n=16). For controls, nondilated aortas were harvested during autopsies from individuals with tricuspid aortic valves and no evidence of aortic valve disease (n=10). Histological and immunohistochemical analyses revealed that compared with control aortas, overall medial degeneration was more severe in AR-aortas (P=0.005) but not AS-aortas (P=0.23). This pathological remodeling included mucoid extracellular matrix accumulation (P=0.005), elastin loss (P=0.003), elastin fragmentation (P=0.008), and decreased expression of fibrillin (P=0.003) and collagen (P=0.008). Furthermore, eNOS (endothelial nitric oxide synthase) expression was decreased in the intima (P=0.0008) and in vasa vasorum (P=0.004) of AR-aortas but not AS-aortas (all P>0.05). Likewise, subendothelial apoptosis was increased in AR-aortas (P=0.03) but not AS-aortas (P=0.50). CONCLUSIONS: AR has a negative effect on the nondilated ascending aortic wall. Accordingly, our results support the need for more detailed studies of the aortic wall in relation to aortic valve disease and may ultimately lead to more aggressive clinical monitoring and/or surgical criteria for patients with relevant AR.

RESUMO

Patients with symptomatic aortic stenosis are often treated with a surgical valve replacement. Surgical bioprosthetic valves degenerate over time and therefore may necessitate a redo surgery. This analysis reports the 2-year clinical outcomes of the Valve-in-Valve study, which evaluated transcatheter aortic valve implantation using the CoreValve and Evolut R devices in patients with degenerated surgical aortic bioprostheses at high risk for surgery. The prospective Valve-in-Valve study enrolled 202 eligible patients with failing surgical aortic bioprostheses due to stenosis, regurgitation, or a combination of both. The Evolut R bioprosthesis was used in 90.5% of valve-in-valve transcatheter aortic valve implantation cases. Two-year all-cause and cardiovascular mortality rates were 16.5% and 11.1%, respectively. Other clinical events included stroke (7.9%), disabling stroke (1.7%), and new pacemaker implantation (10.1%). The 2-year all-cause mortality rate was significantly higher in patients with discharge mean gradients ≥20 mmHg vs. those with lower mean gradients (21.0% vs 7.6%, p = 0.025). Discharge mean gradients ≥20 mm Hg were associated with smaller surgical bioprostheses (OR, 7.2 [95% CI 2.3 to 22.1]. In patients with failing surgical aortic bioprostheses, valve-in-valve treatment using a supra-annular self-expanding bioprosthesis provides significant functional improvements with acceptable rates of complications, especially if a postprocedural mean gradient of <20 mmHg can be achieved.

RESUMO

Mucopolysaccharidosis type VII (MPS VII) is a rare autosomal recessive lysosomal storage disorder. MPS VII is caused by mutations in the GUSB gene that encodes ß-glucuronidase. Adult MPS VII patients present with musculoskeletal abnormalities, coarse features, and corneal clouding. Cardiac and valvular impairment are common; however, severe valvular disease necessitating surgery has not yet been reported. We present a 32-year-old male MPS VII patient admitted to our hospital with decompensated heart failure. We identified aortic valve disease with severe stenosis (valve area 0.69 cm2) and moderate regurgitation. Severe mitral valve stenosis (valve area 1 cm2) with moderate to severe regurgitation was also found in the patient. In addition, an occlusion of the right coronary artery (RCA) was documented. The patient underwent surgical replacement of the mitral and aortic valves with mechanical prostheses and implantation of a venous bypass graft to his RCA. The surgery led to a significant improvement of his clinical symptoms. Six months after the procedure, both mechanical valves function normally. Histopathological assessment identified chronic inflammatory infiltrates, fibrosis and calcifications in both resected valves. Foamy cytoplasmic transformation was most evident in the valvular interstitial cells. The ultrastructural vacuolar abnormality seen in these cells corresponded to storage changes observed in other MPSs. In conclusion, we describe clinical findings and valvular pathology in an MPS VII patient with the first-reported successful combined surgical valve replacement and myocardial revascularization. The histological and ultrastructural analyses revealed that the lysosomal storage predominantly affected the valvular interstitial cells.

RESUMO

AIM: The aim of our investigation was to assess the remote results of valve-sparing aortic root reimplantation into the graft (Florida Sleeve technique) compared with reimplantation of the aortic valve into the graft (David technique) during surgical correction of ascending aortic aneurysms accompanied by concomitant aortic insufficiency. PATIENTS AND METHODS: Our single-centre, blind, prospective, randomized study carried out from 2011 to 2015 included a total of 64 patients with ascending aortic aneurysms and aortic insufficiency. The patients were randomized into 2 groups: group I - aortic root reimplantation according to the Florida Sleeve technique (FS group) and group II - reimplantation of the aortic valve according to the T. David technique in David I modification (D group). The groups did not statistically differ by the baseline clinical profile. RESULTS: The overall 7-year survival for the FS group and D group amounted to 83% and 85.6%, respectively (p=0.98). Assessing the competing risks of mortality related to cardiovascular or other causes revealed no differences. Freedom from prosthetic repair of the aortic valve in the remote follow-up period amounted to 92.8% and 85.8% for the FS group and D group, respectively (p=0.4). According to the obtained findings, the technique of a valve-sparing operation is not a predictor of either lethality (RR 0.98 (95% CI 0.23-4.15), p=0.98) or prosthetic repair of the aortic valve (RR 2.03 (95% CI 0.40-14.63), p=0.40) in the remote period of follow up. RCONCLUSION: Aortic root reimplantation inside the prosthesis according to the Florida Sleeve technique makes it possible to simplify and accelerate the procedure of aortic root reconstruction in patients with aortic root aneurysms and concomitant aortic insufficiency, demonstrating long-term results comparable with those of the David technique.

RESUMO

A 42-year-old woman had undergone aortic valve replacement with a 19 mm bioprosthetic valve for aortic stenosis due to a bicuspid valve 8 years before. She was admitted to our hospital for valve re-replacement owing to the prosthetic valve dysfunction. As the patient's valve annulus was markedly thickened owing to pannus formation, we were unable to pass a 19 mm valve sizer through the annulus even after removal of the prosthetic valve and the tissue surrounding the annulus. Valve re-replacement combined with patch enlargement of the aortic annulus was performed to obtain maximally effective orifice area. Her postoperative course was uneventful, and echocardiography revealed no perivalvular leak. In valve re-replacement, it is important to remove the prosthetic valve and the tissue surrounding the annulus to the greatest extent possible and consider patch enlargement of the aortic annulus to avoid patient-prosthesis mismatch in a patient with a small aortic annulus.

RESUMO

Arteritis is an inflammatory disease of the vessel walls, resulting in vascular damage and a wide variety of clinical symptoms and multisystem disorders. Because aneurysmal disease, coronary disease, and aortic insufficiency affect patient prognosis, surgical intervention plays an important role. Preoperatively, systemic vessels, cardiac function, and other major organs should be evaluated. Regarding the surgical technique, reinforcement of the anastomosis to the fragile aortic wall is important to prevent pseudoaneurysmal formation and prosthetic valvular detachment. As aortic root replacement, we have been applying the modified Bentall procedure with a "double fixation technique" and obtained desirable outcomes. Although endovascular repair for aneurysmal disease is one of the treatment options, its longterm efficacy remains uncertain. Postoperative control of inflammation with corticosteroids and/or immunosuppressive agents is also important for long-term management. Pseudoaneurysmal formation and prosthetic valvular detachment may occur progressively over a long period of time. To prevent these complications, strict follow-up with imaging and inflammation control should be performed.

RESUMO

BACKGROUND The worldwide spread of the severe acute respiratory syndrome-coronavirus-2 (SARS-COV-2) has created unprecedented situations for healthcare professionals and healthcare systems. Although infection with this virus is considered the main health problem currently, other diseases are still prevalent. CASE REPORT This report describes a 59-year-old man who presented with symptoms of dyspnea and fever that were attributed to Covid-19 infection. His clinical condition deteriorated and further examinations revealed a subjacent severe aortic regurgitation due to acute infective endocarditis. Surgical treatment was successful. CONCLUSIONS The results of diagnostic tests for Covid-19 should be re-evaluated whenever there are clinical mismatches or doubts, as false-positive Covid-19 test results can occur. Clinical interpretation should not be determined exclusively by the Covid-19 pandemic. This case report highlights the importance of using validated and approved serological and molecular testing to detect infection with SARS-CoV-2, and to repeat tests when there is doubt about presenting symptoms.

RESUMO

AIMS: Data regarding outcomes for patients with severe aortic stenosis (AS) with concomitant aortic insufficiency (AI), undergoing transcatheter aortic valve replacement (TAVR) are limited. This study aimed to analyze the prevalence of severe AS with concomitant AI among patients undergoing TAVR and outcomes of TAVR in this patient group. METHODS AND RESULTS: Using data from the STS/ACC-TVT Registry, we identified patients with severe AS with or without concomitant AI who underwent TAVR between 2011 and 2016. Patients were categorized based on the severity of pre-procedural AI. Multivariable proportional hazards regression models were used to examine all-cause mortality and heart failure (HF) hospitalization at 1-year. Among 54,535 patients undergoing TAVR, 42,568 (78.1%) had severe AS with concomitant AI. Device success was lower in patients with severe AS with concomitant AI as compared with isolated AS. The presence of baseline AI was associated with lower 1 year mortality (HR 0.94 per 1 grade increase in AI severity; 95% CI, 0.91-0.98, P < .001) and HF hospitalization (HR 0.87 per 1 grade increase in AI severity; 95% CI, 0.84-0.91, P < .001). CONCLUSIONS: Severe AS with concomitant AI is common among patients undergoing TAVR, and is associated with lower 1 year mortality and HF hospitalization. Future studies are warranted to better understand the mechanisms underlying this benefit. SHORT ABSTRACT: In this nationally representative analysis from the United States, 78.1% of patients undergoing TAVR had severe AS with concomitant AI. Device success was lower in patients with severe AS with concomitant AI as compared with isolated AS. The presence of baseline AI was associated with lower 1 year mortality (HR 0.94 per 1 grade increase in AI severity; 95% CI, 0.91-0.98, P < .001) and HF hospitalization (HR 0.87 per 1 grade increase in AI severity; 95% CI, 0.84-0.91, P < .001).

RESUMO

Controversy persists regarding the advisability of anticoagulation for the early period after biological surgical aortic valve replacement (AVR). We aim to examine the impact of various antithrombotic regimens on outcomes in a large cohort of biological AVR patients. Records of 1,111 consecutive adult patients who underwent surgical biological AVR at our institution between 2013 and 2017 were reviewed. Outcomes included stroke, bleeding, and death at 3 and 12 months. Treatment regimens included (1) no therapy, (2) anticoagulants (warfarin or Factor Xa inhibitors), (2) antiplateles (various), and (4) anticoagulants + antiplatelets. Kaplan-Meier analysis was used to track outcomes, and Cox-proportional hazards regression models were conducted to analyze effects of different therapies on adverse events. At 3 months, thromboembolic events were low and not significantly different between the no therapy group (2.2%) and anticoagulation (2.8%) or anticoagulation + antiplatelet (3.6%) or all groups (3.7%). The antiplatelet group was just significantly lower, at 2.2%. However, this was driven by non-stroke cardiovascular events in patients with coronary artery disease. The incidence of death at 3 months was low and not significantly different between all groups. At 12 months, there were no thromboembolic benefits between groups, but bleeding events were significantly higher in the anticoagulation group (no therapy (1.4%), anticoagulation (8.4%), antiplatelet (4.5%), anticoagulation + antiplatelet (7.9%)). In conclusion, none of the antithrombotic regimens showed benefits in stroke or survival at 3 or 12 months after biological AVR. Anticoagulation increased bleeding events. Routine anticoagulation after biological AVR appears to be unnecessary and potentially harmful.

RESUMO

OBJETIVO: Reflejar nuestra frustración al perder un paciente, no porque su infrecuente patología sea de por sí muy grave, sino por el acumulo sobreañadido de otros motivos diagnósticos, y terapéuticos en un entorno hospitalario de epidemia Covid-19. MÉTODO: Primero describimos el proceso diagnóstico, terapéutico y evolutivo (27 febrero al 25 marzo 2020) de un varón de 73 años portador de una fístula aorto-entérica secundaria a un bypass aorto-bifemoral, implantado doce años antes en otro hospital. Después presentamos nuestra experiencia (1978-2020) en este tipo de situaciones, y finalmente realizamos una revisión de la literatura (1953-2020) al respecto. RESULTADOS: A) Caso clínico: ausencia de diagnóstico precoz, fracaso de la técnica operatoria elegida, importantes complicaciones postoperatorias (hemorragia, infarto cerebral y neumonía bilateral por coronavirus) que finalizo en exitus. B) Experiencia personal: cuatro casos (incluido el referido). C) Revisión de la literatura: tres revisiones sistemáticas: 564 casos (1953-1993); 386 casos en 58 publicaciones (1991-2006), 823 pacientes en 216 publicaciones (1995-2015) y 20 casos en 14 publicaciones (2016-2020). CONCLUSIÓN: Si en situaciones normales una fístula aorto-entérica es una condición que amenaza seriamente la vida del paciente (hemorragia y/o infección), no debe extrañar que en situaciones excepcionales esa situación de gravedad se incremente. No obstante, de estas malas experiencias estamos obligados a sacar enseñanzas que beneficien a otros en el futuro


OBJECTIVE: To reflect our frustration when losing a patient, not because their infrequent pathology is in itself very serious, but because of the accumulation of other diagnostic and therapeutic reasons in a hospital environment of the Covid-19 epidemic. METHOD: First we describe the diagnostic, therapeutic and evolutionary process (February 27 to March 25, 2020) of a 73-year-old male with an aorto-enteric fistula secondary to an aorto-bifemoral bypass, implanted twelve years earlier in another hospital. Then we present our experience (1978-2020) in this type of situation, and finally we carried out a review of the literature (1953-2020) in this regard. RESULTS: A) Clinical case: absence of early diagnosis, failure of the chosen operative technique, significant postoperative complications (hemorrhage, cerebral infarction and bilateral coronavirus pneumonia) that ended in death. B) Personal experience: four cases (including the referred one). C) Literature review: three systematic reviews: 564 cases (1953-1993); 386 cases in 58 publications (1991-2006), 823 patients in 216 publications (1995-2015) and 20 cases in 14 publications (2016-2020). CONCLUSION: If in normal situations an aorto-enteric fistula is a condition that seriously threatens the patient's life (hemorrhage and / or infection), it should not be surprising that in exceptional situations this serious situation increases. However, from these bad experiences we are obliged to draw lessons that will benefit others in the future

We report on a case of a 57-year-old male patient, who underwent full root replacement in 2005 and now presented with high grade aortic insufficiency. On admission, the patient underwent a computed tomography scan which demonstrated interstitial infiltration in the left lung, highly suspicious for a COVID-19 infection that could not be confirmed by reverse transcription polymerase chain reaction (RT-PCR) testing. As there usually is a delay between infection and positive RT-PCR test results, the initial decision was to perform additional testing. However, the patient deteriorated quickly in spite of optimal medical therapy making urgent aortic valve replacement necessary. We decided to perform transcatheter aortic valve replacement to avoid cardiopulmonary bypass with shorter operative times, presumably shorter ventilation times and duration of intensive care unit stay, and thus a lesser risk for pulmonary complications.

RESUMO

Background: Paravalvular leak (PVL) is common after transcatheter aortic valve implantation (TAVI) and has been linked with worse survival. This study aimed to investigate the determinants and outcome of PVL after TAVI and determine the role of aortic valve calcification (AVC) distribution in predicting PVL. Methods and Results: This was a retrospective cohort study of 270 consecutive patients who underwent TAVI. Determinants and outcomes of ≥mild PVL were assessed. Matching rates of PVL jet with AVC distribution were calculated. AVC volume, larger annulus dimensions, and transvalvular peak velocity were risk factors for ≥mild PVL after TAVI. AVC volume was an independent predictor of ≥mild PVL. On the other hand, annulus ellipticity, left ventricular outflow tract nontubularity, and diameter-derived prosthesis mismatch were not found to predict PVL after TAVI. PVL jet matched, in varying proportions, with calcification at all aortic root regions, and the highest matching rate was with calcifications at body of leaflets. Moreover, matching rates were less with commissure compared to cusp calcifications. Mild or greater PVL was not associated with all-cause and cardiovascular mortality up to 1-year follow-up. Conclusion: ≥mild PVL after TAVI is common and can be predicted by aortic root calcification volume, larger annulus dimensions, and pre-TAVI transvalvular peak velocity, with calcification volume being an independent predictor for PVL. However, annulus ellipticity, left ventricular outflow tract nontubularity, and diameter-derived prosthesis mismatch had no role in predicting PVL. Importantly, body of leaflet calcifications (versus annulus and tip of leaflet) and cusp calcifications (versus commissure calcification) are more important in predicting PVL. No association between ≥mild PVL and increased risk of all-cause and cardiovascular mortality at 1-year follow-up.

RESUMO

BACKGROUND: As the average age of patients with severe aortic stenosis (AS) who receive procedural intervention continue to age, the need for non-invasive modalities that provide accurate diagnosis and operative planning is increasingly important. Advances in cardiovascular magnetic resonance (CMR) over the past two decades mean it is able to provide haemodynamic data at the aortic valve, along with high fidelity anatomical imaging. METHODS: Electronic databases were searched for studies comparing CMR to transthoracic echocardiography (TTE) and transoesophageal echocardiography (TEE) in the diagnosis of AS. Studies were included only if direct comparison was made on matched patients, and if diagnosis was primarily through measurement of aortic valve area (AVA). RESULTS: Twenty-three relevant, prospective articles were included in the meta-analysis, totalling 1040 individual patients. There was no significant difference in AVA measured as by CMR compared to TEE. CMR measurements of AVA size were larger compared to TTE by an average of 10.7% (absolute difference: + 0.14cm2, 95% CI 0.07-0.21, p < 0.001). Reliability was high for both inter- and intra-observer measurements (0.03cm2 +/- 0.04 and 0.02cm2 +/- 0.01, respectively). CONCLUSIONS: Our analysis demonstrates the equivalence of AVA measurements using CMR compared to those obtained using TEE. CMR demonstrated a small but significantly larger AVA than TTE. However, this can be attributed to known errors in derivation of left ventricular outflow tract size as measured by TTE. By offering additional anatomical assessment, CMR is warranted as a primary tool in the assessment and workup of patients with severe AS who are candidates for surgical or transcatheter intervention.
