RESUMO

Transcatheter aortic valve implantation (TAVI) is a rapidly evolving treatment option with an inherent risk of causing cerebral infarctions. The mechanism of cerebral infarction during TAVI mainly involves embolisms from the aortic wall and valve. Transoesophageal echocardiography (TEE) is useful for detecting aortic atheromas. We present the case of a patient in whom the dispersal of aortic atheromas was monitored by TEE during TAVI. This report demonstrates the importance of preoperatively predicting embolisms from aortic atheromas in patients with severe aortic stenosis.

RESUMO

As our population ages, the demand for surgical services in older people is increasing exponentially. Shown to be indispensable in the care of medical patients, use of the comprehensive geriatric assessment (CGA) is also growing in the perioperative setting. We present the case of a previously independent 82-year-old man who underwent a standard preoperative assessment and surgical aortic valve replacement. In the 7 months that followed, prior to his death, he suffered a rapid functional decline contributed to by slow postoperative recovery, delirium and recurrent falls. Post-mortem revealed cardiac amyloid deposition and extensive small vessel disease in the brain. This case highlights the importance of the CGA in the perioperative management of older patients, especially in identification and optimisation of geriatric syndromes and consideration of less-invasive alternative treatments. We review the existing literature on CGA use in cardiothoracic and vascular surgical settings, drawing on experiences learnt from the above case.

RESUMO

We report a case of a 77-year-old male who had been diagnosed with normal-flow high-pressure gradient severe aortic stenosis (AS) two years previously. In accordance with his wishes, it was decided not to perform surgery. He visited our hospital with anorexia and weight loss and was diagnosed with gastric cancer. Echocardiography showed a change to paradoxical low-flow low-pressure gradient severe AS (PLFLPG AS). A decrease in stroke volume is typically associated with a smaller LV size, but the reason for a smaller LV size in PLFLPG AS remains unclear. In this case, the change to PLFLPG AS was thought to be due to a decrease in whole body oxygen consumption, and this may help to understand the pathology.

RESUMO

Left ventricular (LV) remodeling with aortic stenosis (AS) appears to differ according to sex, but reverse remodeling after transcatheter aortic valve implantation (TAVI) has not been elucidated in a Japanese population. This study aims to determine whether any sex-related differences in LV or reverse remodeling after TAVI exist in the context of severe AS.Of 208 patients who received TAVI for severe AS in our institution, 100 (men, 42; mean age, 83.0 ± 4.9 years) underwent transthoracic echocardiography before and 3 months after TAVI. Despite similar valvular gradients, women with severe AS had lower indexed LV mass (LVMi) than did men (152.3 ± 35.4 versus 173.2 ± 44.6 g/m2, P = 0.005), with smaller indexed LV end-diastolic (LVEDVi) (50.2 ± 13.3 versus 61.4 ± 20.7 mL/m2, P = 0.001) and end-systolic (LVESVi; 17.9 ± 8.7 versus 24.3 ± 13.8 mL/m2, P = 0.006) volumes. After TAVI, women (-6.0% ± 14.4%) had higher reduction in the rate of change of relative wall thickness (RWT) than did men (4.4% ± 19.0%, P = 0.003). Men (-8.9% ± 3.9%) had higher reduction in the rate of change of LVEDVi than did women (1.5% ± 3.3%, P = 0.045). Incidence of LV reverse remodeling defined as a reduction in LVESV of >15% was significantly higher in men (50%) than in women (26%, P = 0.013).In addition to sex differences in the pattern of LV remodeling with AS, reverse LV remodeling after TAVI also differed between sexes.

RESUMO

Whether the subtype of atrial fibrillation affects outcomes after transcatheter aortic valve replacement for aortic stenosis is unclear. The nationwide FinnValve registry included 2130 patients who underwent primary after transcatheter aortic valve replacement for aortic stenosis during 2008-2017. Altogether, 281 (13.2%) patients had pre-existing paroxysmal atrial fibrillation, 651 (30.6%) had pre-existing non-paroxysmal atrial fibrillation and 160 (7.5%) were diagnosed with new-onset atrial fibrillation during the index hospitalization. The median follow-up was 2.4 (interquartile range: 1.6-3.8) years. Paroxysmal atrial fibrillation did not affect 30-day or overall mortality (p-values >0.05). Non-paroxysmal atrial fibrillation demonstrated an increased risk of overall mortality (hazard ratio: 1.61, 95% confidence interval: 1.35-1.92; p<0.001), but not 30-day mortality (p = 0.084). New-onset atrial fibrillation demonstrated significantly increased 30-day mortality (hazard ratio: 2.76, 95% confidence interval: 1.25-6.09; p = 0.010) and overall mortality (hazard ratio: 1.68, 95% confidence interval: 1.29-2.19; p<0.001). The incidence of early or late stroke did not differ between atrial fibrillation subtypes (p-values >0.05). In conclusion, non-paroxysmal atrial fibrillation and new-onset atrial fibrillation are associated with increased mortality after transcatheter aortic valve replacement for aortic stenosis, whereas paroxysmal atrial fibrillation has no effect on mortality. These findings suggest that non-paroxysmal atrial fibrillation rather than paroxysmal atrial fibrillation may be associated with structural cardiac damage which is of prognostic significance in patients with aortic stenosis undergoing transcatheter aortic valve replacement.

RESUMO

Assessment of right ventricular (RV) systolic function in patients with significant secondary tricuspid regurgitation (STR) remains challenging. In patients with severe aortic stenosis treated with transcatheter aortic valve implantation (TAVI), STR and RV enlargement have been associated with poor outcomes. In these patients, speckle tracking echocardiography (STE) may detect RV systolic dysfunction better than 3-dimensional (3D) RV ejection fraction (EF). The purpose of this study was to investigate the prevalence of RV dysfunction when assessed with STE in patients with significant STR (≥3+) compared with patients without significant STR (<3+) matched for 3D RV dimensions and RVEF on dynamic computed tomography (CT). Patients with dynamic CT data before TAVI were evaluated retrospectively. To assess the performance of RV-free wall strain (RVFWS) for identifying patients with impaired RV systolic function, patients were subsequently matched 1:1 based on age, gender, indexed RV end-diastolic volume (RVEDVi), indexed RV end-systolic volume (RVESVi), RVEF, and left ventricular ejection fraction (LVEF). In a total 267 patients (80 ± 8 years, 48% male), significant STR (≥3+) was observed in 67 patients. Patients with STR≥3+ had larger RVEDVi, larger RVESVi, lower LVEF, and more impaired RVFWS compared with patients with STR<3+ (n = 200). After propensity score matching, patients with STR≥3+ (n = 53) had significantly more impaired RVFWS compared with patients with STR<3+ (n = 53): -18.2 ± 5.0% versus -21.1 ± 3.7%, p = 0.001. In conclusion, patients with significant STR have more pronounced RV systolic dysfunction as assessed with STE than the patients without significant STR despite having similar 3D RV dimensions and RVEF on dynamic CT.

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

Scarce data exist on clinical features and prognosis of patients with severe aortic stenosis (AS), concomitant with left ventricular obstruction (LVO). We aimed to evaluate the prevalence, characteristics, and outcomes in patients with severe AS and LVO undergoing transcatheter aortic valve implantation (TAVI). Consecutive patients with severe AS undergoing TAVI between January 2013 to December 2017 at our institution were included. Significant LVO was defined as resting peak left ventricular (LV) systolic gradient ≥30 mm Hg on pre-TAVI echocardiography. We analyzed the primary composite outcome of all-cause mortality and rehospitalization for heart failure (HHF) at 1-year in patients with LVO and those without LVO in the overall and propensity-matched populations. Among 1,729 patients who underwent TAVI, significant LVO was observed in 31 (1.8%) patients. This group was more likely to be female, had smaller aortic annulus and LV cavity, and received a smaller size of the transcatheter heart valve. The most common phenotype of LV hypertrophy causing LVO was concentric LV hypertrophy (58%), and mid-LV obstruction was more common than LV outflow tract obstruction (77% vs 23%, respectively). After adjustment for baseline differences, the primary outcome was not significantly different between patients with LVO and those without LVO (15% vs 16%, respectively; hazard ratio: 0.83; 95% confidence interval: 0.19 to 3.72; p = 0.809). In conclusion, in patients undergoing TAVI, concomitant LVO was relatively uncommon and occurred more often at mid-LV. The presence of pre-TAVI LVO was not associated with worse outcomes defined as increase all-cause mortality or HHF at 1-year.

RESUMO

Data regarding the longitudinal effect of catheter procedure-related acute kidney injury (AKI) on clinical outcomes are limited. This study aimed to assess the late adverse cardiorenal events of AKI following transcatheter aortic valve implantation (TAVI). A total of 2,518 patients who underwent TAVI, excluding in-hospital deaths, were enrolled from the Japanese multicenter registry. The definition of AKI was determined using the Valve Academic Research Consortium-2 criteria. The incidence, predictors, major adverse renal and cardiac events (MARCE), and all-cause mortality of AKI were evaluated. MARCE included readmission for renal and heart failure (HF), hemodialysis requirement, and cardiovascular-renal death during the follow-up period. The incidence of AKI was 9.7% in the entire cohort. The significant predictive factors of AKI were men, diabetes mellitus, hypertension, chronic kidney disease, low albumin, overdose of contrast media, nontransfemoral approach, transfusion, vascular complications, and new pacemaker implantation. The rates of HF readmission and future hemodialysis were significantly higher in patients with AKI than in those without AKI (19.7% vs 9.0%, p <0.001, 3.3% vs 0.4%, p <0.001, respectively). Cox regression multivariate analysis showed that AKI occurrence was an independent predictive factor for the incremental risk of both MARCE and late mortality up to 4 years (hazard ratio [HR] 1.59, 95% confidence interval [CI] 0.75 to 1.20, p <0.001, HR 2.18, 95% CI 1.70 to 2.79; p <0.001, respectively). In conclusion, AKI occurrence was significantly associated with late adverse cardiorenal events after TAVI. Adequate clinical management can be expected to reduce AKI-related late phase cardiorenal damage even after successful TAVI.

RESUMO

OBJECTIVE: Aortic stenosis may be complicated by an acquired von Willebrand syndrome that rarely causes significant bleeding, raising the question of why it does so in a few cases. To seek an explanation, we studied 5 severe bleeder aortic stenosis patients in a cohort of 49 patients, using the flowchart for inherited von Willebrand disease. Approach and Results: All 5 patients were lacking in large and intermediate VWF (von Willebrand factor) multimers, 3 had reduced plasma and platelet VWF levels, and none showed PFA100 closure. Two patients (those with most multimers missing) also had a short VWF half-life. Genetic analyses on the 3 patients with reduced platelet VWF levels revealed that one carried both the c.1164C>G and the c.7880G>A mutations, and another carried the c.3390C>T mutation, while the third had one of the 2 VWF alleles relatively less expressed than the other (25% versus 75%). No genetic alterations emerged in the other 2 patients. Successful replacement of the stenotic aortic valve, performed in the 2 patients with VWF mutations, did not correct their abnormal VWF multimer picture-unlike what happened in the aortic stenosis patients without bleeding symptoms. CONCLUSIONS: Our findings suggest that acquired von Willebrand syndrome can develop in patients with hitherto-undiagnosed inherited von Willebrand disease. Since von Willebrand disease is the most common bleeding disorder, this possibility should be considered in aortic stenosis patients-especially those with a more severe bleeding history and more disrupted VWF laboratory patterns-because they risk hemorrhage during aortic valve replacement.

RESUMO

BACKGROUND: The management of patients with coexisting severe aortic stenosis (AS) and coronary artery disease (CAD) is still facing a great deal of uncertainty when it comes to choosing between the entire surgical versus the complete percutaneous approaches, after accurately balancing risks versus outcomes. AIM: To evaluate clinical outcomes and mortality of transcatheter aortic valve replacement (TAVR) plus percutaneous coronary intervention (PCI) compared with surgical aortic valve replacement (SAVR) plus coronary arteries bypass grafting (CABG) procedures in patients with concomitant AS and CAD. METHODS: Electronic databases of PubMed, EMBASE, and SCOPUS were searched for relevant articles assessing outcome parameters of interest. The study endpoints were the rate of overall myocardial infarction and stroke within 30 days and the rate of 30-day mortality and 2-year mortality between patients with TAVR/PCI and those with SAVR/CABG. RESULTS: Random-effect meta-analysis did not reveal any significant difference between 30-day safety outcomes: myocardial infarction (TAVR/PCI vs SAVR/CABG: odds ratio [OR]: 0.52; 95% confidence interval [CI]: 0.20-1.33; I2 = 0%), stroke (TAVR/PCI vs SAVR/CABG: OR: 0.88; 95% CI: 0.45-1.73; I2 = 0%). No significant difference in 30-day mortality (OR: 0.72; 95% CI: 0.43-1.21; I2 = 0%) and 2-year mortality (OR: 1.50; 95% CI: 0.77-2.94; I2 = 81%) rate was noted between patients with TAVR/PCI and those with SAVR/CABG. CONCLUSIONS: When comparing the total percutaneous and total surgical treatment, no significant difference in short-term safety outcomes or early and late mortality was observed. More evidence is needed to guide the clinical decision.

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

Patients with Shone complex (SC) have multiple left-sided obstructive lesions and thus are at risk for left ventricular (LV) remodeling, LV diastolic dysfunction and pulmonary hypertension. Yet, to date, there has been no description of hemodynamics in adults with SC. Retrospective chart review of 25 patients with SC who underwent cardiac catheterization at Mayo Clinic, MN between 2002 and 2019 was performed. SC was defined as multiple left-sided obstructive lesions in the presence of an anatomically abnormal mitral valve. Median age was 32 years (22.5, 42) and 15 patients (60%) were female. The majority of patients (84%) had history of coarctation of the aorta, 10 (40%) had subaortic stenosis, 11 (44%) had prior aortic valve replacement, and 10 (40%) had prior mitral valve replacement. Structural disease at the time of catheterization which warranted intervention within the next year was present in 13 patients (52%). The mean LV end-diastolic pressure was 21.3 ± 9.0 mm Hg (>15 mm Hg in 71%), pulmonary artery peak systolic pressure was 55.4 ± 13.4 mm Hg, and the pulmonary artery mean pressure was 37.0 ± 9.4 mm Hg (>20 mm Hg in 96%). During a mean follow-up of 8.3 ± 4.4 years, there were 7 deaths (28%) and 3 additional patients (12%) underwent cardiac transplantation. In conclusion, adults with SC who underwent catheterization showed significant left-sided heart and pulmonary vascular remodeling. Elevated LV end-diastolic pressure and pulmonary artery pressures were highly prevalent. There were high mortality and cardiac transplant rates in our cohort.

RESUMO

Hemodialysis (HD) is one of the important risks for the development of cardiovascular disease, including aortic valve stenosis (AS). Although aortic valve replacement (AVR) is a beneficial treatment for AS, HD patients are known to show a high rate of mortality after AVR than non-HD patients.We retrospectively studied 109 patients who underwent AVR for severe AS, 18 of which were HD patients. Survival rate after AVR, preoperative clinical data, and surgical procedure were investigated.In preoperative clinical features, left ventricular end-diastolic diameter was larger, intraventricular septum thickness (IVST) was thicker, left ventricular mass index (LVMI) was higher, left ventricular ejection fraction was lower, E/e' was higher, and pulmonary arterial wedge pressure (PAWP) was higher in the HD group than in the non-HD group. During a follow-up period of 3.2 ± 2.3 years after AVR, patients receiving HD had a worse prognosis than those without HD treatment: the 3-year survival rate after surgery in the HD group was 36.2% and that in the non-HD group was 84.9%. With regard to prognostic factors in the whole cohort, significant differences were found in IVST, LVMI, E/e', PAWP, and HD. In patients receiving HD, abnormally high PAWP for their right atrial pressure (RAP) was observed, suggesting that PAWP and RAP were discordant, and univariate analysis revealed that high PAWP was the only predictor of mortality in HD patients after surgery.Preoperative PAWP with a discordant pattern in HD patients might be an important prognostic predictor after AVR.

RESUMO

Polycytemia vera (PV) is a rare myeloproliferative neoplasm associated with microcirculatory disturbances, thrombosis and bleeding. Patients suffering from PV have a high risk of perioperative adverse events, but the literature regarding on-pump procedures in PV patients is scarce. We report two cases of acute and severe oxygenator failure during cardiopulmonary bypass and present valid exit scenarios.

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: One out of seven patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR) may be affected by transthyretin cardiac amyloidosis (ATTR-CA), mostly presenting with low-flow low-gradient AS with mildly reduced ejection fraction. The complex interaction of these two pathologies poses specific diagnostic and management challenges. The prognostic implications of this clinical intersection are not defined yet. Moreover, whether TAVR may have a prognostic benefit in ATTR-CA patients with symptomatic severe AS remains unclear, posing doubts on the best management strategy in this increasingly recognized subset of patients. CLINICAL CASE: We present a case of an 87-year old man with low-flow low-gradient severe AS, for whom a diagnosis of ATTR-CA was suspected based on clinical and echocardiographic criteria specific to coexisting AS and ATTR-CA. The diagnosis was eventually confirmed by positive bone tracer scintigraphy imaging. Following in-depth Heart team discussion, integrating frailty and prognostic information from combined cardiomyopathy states, a decision was made to manage the patient's severe AS conservatively. CONCLUSION: In the presented case, we deemed the natural history of ATTR-CA amyloidosis to negatively affect both the patient' prognosis and procedural risk, adversing TAVR indication despite symptomatic severe AS. No clear evidence is currently available to guide decision making in this setting, advocating for prospective studies to clarify if TAVR may have a prognostic benefit in ATTR-CA - and which ATTR-CA - patients.

RESUMO

The novel coronavirus disease-2019 (COVID-19) pandemic has created uncertainty in the management of patients with severe aortic stenosis. This population experiences high mortality from delays in treatment of valve disease but is largely overlapping with the population of highest mortality from COVID-19. The authors present strategies for managing patients with severe aortic stenosis in the COVID-19 era. The authors suggest transitions to virtual assessments and consultation, careful pruning and planning of necessary testing, and fewer and shorter hospital admissions. These strategies center on minimizing patient exposure to COVID-19 and expenditure of human and health care resources without significant sacrifice to patient outcomes during this public health emergency. Areas of innovation to improve care during this time include increased use of wearable and remote devices to assess patient performance and vital signs, devices for facile cardiac assessment, and widespread use of clinical protocols for expedient discharge with virtual physical therapy and cardiac rehabilitation options.
