RESUMO

Hypertension remains a leading preventable cause of myocardial infarction, stroke, kidney disease, and cardiovascular death worldwide. Despite lifestyle modifications and intensification of medical therapy, suboptimal blood pressure control is common, spurring the development of device-based therapies for hypertension. The US Food and Drug Administration (FDA) assembled the Circulatory System Devices Panel on August 22-23, 2023, to discuss the safety and effectiveness of renal denervation devices manufactured by Recor Medical and Medtronic. After reviewing the ultrasound-based Recor Paradise renal denervation system the day prior, the panel reconvened to discuss the radiofrequency-based Medtronic Symplicity Spyral Renal Denervation System. In this manuscript, we summarize the data presented by the sponsor and FDA and detail the deliberation and discussion during the meeting.

RESUMO

Tricuspid regurgitation (TR) is common and associated with significant mortality and morbidity. Because the effectiveness and safety of medical and surgical treatments are limited, there is a significant unmet need for the treatment of this disease. Therefore, there is a growing market for percutaneous devices that offer safer, less invasive, and more effective treatment options in this patient population. On February 13, 2024, the US Food and Drug Administration (FDA) convened a meeting of the Circulatory System Devices Panel to discuss the safety and effectiveness of the TriClip Transcatheter Valve Repair System (Abbott, Santa Clara, CA, USA). Several important points were discussed, including newly published data from the TRILUMINATE Pivotal study, the use of patient-oriented outcomes for device approval, and a discussion about training requirements and rollout plans when approving a breakthrough device. In this manuscript, we summarize the data presented by the sponsor and FDA and describe the deliberations and discussions during the meeting.

RESUMO

In the absence of standardized management guidelines, coronary artery aneurysms (CAAs) present therapeutic challenges. Percutaneous coronary intervention (PCI) is rarely explored, especially in giant aneurysms with persistent angina, where surgery might be presumed as a preferred option. We describe the technical aspects and feasibility of PCI using Gore Viabahn expanded polytetrafluoroethylene (ePTFE)-covered nitinol self-expanding stents in a 66-year-old woman with a complex medical history and an enlarging, symptomatic right coronary artery aneurysm. The case was complicated by endoleak after the first stent, but intravascular ultrasound guidance enabled the precise deployment of additional stents, resulting in the successful exclusion of the aneurysm. This case demonstrates steps to successful CAA PCI with Gore Viabahn ePTFE-covered nitinol self-expanding stents and emphasizes that in unsuitable surgical candidates, PCI might be a potential alternative for symptomatic CAAs.

RESUMO

Hypertension continues to be a prominent, avoidable factor contributing to major vascular issues on a global scale. Even with lifestyle adjustments and more aggressive medical treatments, maintaining optimal blood pressure levels remains challenging. This challenge has driven the emergence of device-oriented approaches to address hypertension. To assess the safety and efficacy of the Recor Paradise Ultrasound Renal Denervation System, the Circulatory System Devices Panel was convened by the US Food and Drug Administration (FDA). This manuscript provides a condensed overview of the information put forth by the sponsor and the FDA, along with an account of the considerations and conversations that took place during the meeting.

RESUMO

Underexpanded stents are a dreaded complication of percutaneous coronary intervention (PCI) and are a major predictor of stent thrombosis and in-stent restenosis. Lesion preparation and plaque modification before stent implantation are essential to prevent stent underexpansion and optimize the technical outcomes of PCI. Once stent underexpansion occurs, the treatment options are limited. New devices for the treatment of complex calcified lesions have emerged in the past few years, and experience has accumulated with their use in the treatment of underexpanded stents. This review aims to provide an evidence-based, practical summary of the approach to stent underexpansion, with particular attention to the expected luminal gain, complication rates, and technical nuances of various treatment options. These modalities include the ultrahigh pressure OPN noncompliant balloon, excimer laser coronary angioplasty, rotational and orbital atherectomy, and intravascular lithotripsy. The data gathered for each of these modalities and our experience in treating this complex condition were used to formulate a treatment algorithm for such cases.

RESUMO

BACKGROUND: The use of vascular closure devices (VCDs) to achieve quick and safe hemostasis after femoral arterial access is widely accepted. Major complications include bleeding and occlusion of the femoral artery due to device failure, which often necessitates vascular intervention. This manuscript details our peripheral percutaneous endovascular interventional (PEI) approach for the management of femoral artery occlusion resulting from Angio-Seal (Terumo, Somerset, New Jersey, USA) VCD deployment. METHODS: Consecutive patients who developed occlusive complications after Angio-Seal deployment underwent PEI to overcome specific complications. Patients' clinical and procedural characteristics, along with their short- and long-term follow-up data, were analyzed. RESULTS: The study cohort included 40 patients who experienced Angio-Seal occlusive complications between July 2013 and September 2023. The mean age of the patients was 74 ± 10 years and 55% were female. All the patients were treated with PEI, with an overall procedural success rate of 100%. The primary approach for PEI was directional atherectomy, which was used in 35 cases (88%), followed by balloon, while a cutting balloon was used in 5 patients (13%). Stenting served as the definitive therapy in only 7 patients (18%). No procedural complications or conversions to surgery were observed. During a median follow-up of 244 (IQR = 100-707) days, none of the patients required re-intervention related to Angio-Seal occlusion and salvage intervention. CONCLUSION: In the management of Angi-Seal VCD-related femoral artery occlusion, the adjunctive use of directional atherectomy followed by balloon angioplasty was effective and safe, allowing re-establishment of flow with excellent long-term outcomes.

RESUMO

BACKGROUND: Malnutrition is associated with poor prognosis in several cardiovascular diseases; however, its role in patients with secondary mitral regurgitation (SMR) is poorly known. AIMS: To evaluate the impact of nutritional status, assessed using different scores, on clinical outcomes in patients with SMR undergoing transcatheter edge-to-edge repair (TEER) in a real-world setting. METHODS: A total of 658 patients with SMR and complete nutritional data were identified from the MIVNUT registry. Nutritional status has been assessed using controlling nutritional status index (CONUT), prognostic nutritional index (PNI), and geriatric nutritional risk index (GNRI) scores. Outcomes of interest were all-cause mortality and all-cause mortality or heart failure (HF) hospitalization. RESULTS: Any malnutrition grade was observed in 79.4%, 16.7%, and 47.9% of patients by using CONUT, PNI, and GNRI, respectively, while moderate to severe malnutrition was noted in 24.7%, 16.7%, and 25.6% of patients, respectively. At a median follow-up of 2.2 years, 212 patients (32.2%) died. Moderate-severe malnutrition was associated with a higher rate of all-cause mortality (HR: 2.46 [95% CI: 1.69-3.58], HR: 2.18 [95% CI: 1.46-3.26], HR: 1.97 [95% CI: 1.41-2.74] for CONUT, PNI, and GNRI scores, respectively). The combined secondary endpoint of all-cause mortality and HF rehospitalization occurred in 306 patients (46.5%). Patients with moderate-severe malnutrition had a higher risk of the composite endpoint (HR: 1.56 [95% CI: 1.20-2.28], HR: 1.55 [95% CI: 1.01-2.19], HR: 1.36 [95% CI: 1.02-1.80] for CONUT, PNI, and GNRI scores, respectively). After adjustment for multiple confounders, moderate-severe malnutrition remained independently associated with clinical outcomes. CONCLUSIONS: Moderate-severe malnutrition was common in patients with SMR undergoing TEER. It was independently associated with poor prognosis regardless of the different scores used.

RESUMO

BACKGROUND: Transcatheter edge to edge repair (TEER) improves prognosis in patients with functional mitral regurgitation (FMR) receiving guideline directed medical therapy (GDMT). Many patients with FMR do not receive GDMT and the utility of TEER in this population remains unclear. METHODS: We retrospectively studied patients undergoing TEER. Clinical, echocardiographic and procedural variables were recorded. GDMT was defined as use of RAAS inhibitors and MRAs unless GFR was under 30 as well as beta blockers. The primary endpoint of the study was one year mortality. RESULTS: 168 patients (mean age 71.3 ± 9.3; 66% males) with FMR who underwent TEER were included of whom 116 (69%) received GDMT at the time of TEER and 52 (31%) did not. There were no significant demographic or clinical differences between the groups. There were no significant differences in procedural success and complications between groups. One year mortality was identical in the two groups (15% vs. 15%; RR 1.06, CI 0.43-2.63, P = 0.90). CONCLUSIONS: Our findings suggest that procedural success and one year mortality following TEER was not significantly different in HFREF patients with FMR with or without GDMT. Larger, prospective studies are necessary to define the benefit of TEER in this population.

RESUMO

AIMS: Severe mitral regurgitation (MR) following acute myocardial infarction (MI) is associated with high mortality rates and has inconclusive recommendations in clinical guidelines. We aimed to report the international experience of patients with secondary MR following acute MI and compare the outcomes of those treated conservatively, surgically, and percutaneously. METHODS AND RESULTS: Retrospective international registry of consecutive patients with at least moderate-to-severe MR following MI treated in 21 centres in North America, Europe, and the Middle East. The registry included patients treated conservatively and those having surgical mitral valve repair or replacement (SMVR) or percutaneous mitral valve repair (PMVR) using edge-to-edge repair. The primary endpoint was in-hospital mortality. A total of 471 patients were included (43% female, age 73 ± 11 years): 205 underwent interventions, of whom 106 were SMVR and 99 PMVR. Patients who underwent mitral valve intervention were in a worse clinical state (Killip class ≥3 in 60% vs. 43%, P < 0.01), but yet had lower in-hospital and 1-year mortality compared with those treated conservatively [11% vs. 27%, P < 0.01 and 16% vs. 35%, P < 0.01; adjusted hazard ratio (HR) 0.28, 95% confidence interval (CI) 0.18-0.46, P < 0.01]. Surgical mitral valve repair or replacement was performed earlier than PMVR [median of 12 days from MI date (interquartile range 5-19) vs. 19 days (10-40), P < 0.01]. The immediate procedural success did not differ between SMVR and PMVR (92% vs. 93%, P = 0.53). However, in-hospital and 1-year mortality rates were significantly higher in SMVR than in PMVR (16% vs. 6%, P = 0.03 and 31% vs. 17%, P = 0.04; adjusted HR 3.75, 95% CI 1.55-9.07, P < 0.01). CONCLUSIONS: Early intervention may mitigate the poor prognosis associated with conservative therapy in patients with post-MI MR. Percutaneous mitral valve repair can serve as an alternative for surgery in reducing MR for high-risk patients.

RESUMO

BACKGROUND: The pathogenesis of atherosclerosis is multifactorial, mainly driven by complex inflammatory processes. Colchicine is an anti-inflammatory drug used in a variety of clinical settings. The purpose of this review is to evaluate the role of colchicine in atherosclerotic vascular disease and more specifically, its promising impact on the outcome of patients with stable and acute coronary syndrome and to review its effect in patients undergoing angioplasty. A literature review was performed using the search terms colchicine, coronary heart disease, or acute coronary syndrome, stable coronary disease. We accessed PubMed, Google scholar, and the Cochrane Library databases to search for studies. Patients with chronic coronary disease may benefit from treatment with low dose colchicine to reduce the occurrence of a cardiovascular event. Among patients with a recent myocardial infarction, colchicine treatment was associated with reduced ischemic cardiovascular events, although without a meaningful difference in mortality. Colchicine was found to be a promising agent that can be potentially integrated into the armamentarium of treatments for patients with atherosclerotic coronary disease pending careful patient selection.

RESUMO

BACKGROUND: Transcatheter aortic valve implantation related thrombocytopenia (TAVI-rTP) is an inevitable phenomenon. However, no study has been performed on TAVI-rTP in the current setting of extended clinical indications combined with technology improvements. METHODS: Patients with severe symptomatic aortic stenosis who underwent transfemoral TAVI, from January 2016 to December 2019 were enrolled. RESULTS: Two-hundred and one consecutive patients (mean age 81.1 ± 7.1 years, 96 men) enrolled. Platelet count was recorded before and after aortic valve implantation. Dropped platelet count (DPC) occurred in all but 11 patients who were included. Two groups were created: DPC <30 and DPC ≥30%. DPC was compared with in-hospital major adverse cardiovascular events. The mean DPC was 26 ± 14%. We found that 67 patients (33.3%) had DPC of more or equal to 30%. In the univariable analysis, the time of the procedure (94.4 ± 32.7 vs 79.4 ± 21.9, p = .002), the amount of the contrast used (125.4 ± 55.4 vs 108.4 ± 44.1, p = .02) and the residual AV gradient (13.3 ± 7.2 vs 14.7, p = .05) were related to a DCP ≥30%. A DPC ≥30% was associated with increased risk of life-threatening/major bleeding (11.9% vs 1.5%, p = .001), major vascular complications (16.4% vs 5.2% p = .009) and death (3.0% vs 0%, p = .044) at 30 days. After multivariable analysis, the factors associated with a higher DPC were time and contrast. CONCLUSION: Contemporary TAVI-rTP in this cohort of patients continues to be a common phenomenon but severe thrombocytopenia is less frequent. Patients developing a DPC ≥30% are associated with poor outcomes at 30 days.

RESUMO

OBJECTIVES: To assess outcomes in patients with acute mitral regurgitation (MR) following acute myocardial infarction (AMI) who received percutaneous mitral valve repair (PMVR) with the MitraClip device and to compare outcomes of patients who developed cardiogenic shock (CS) to those who did not (non-CS). BACKGROUND: Acute MR after AMI may lead to CS and is associated with high mortality. METHODS: This registry analyzed patients with MR after AMI who were treated with MitraClip at 18 centers within eight countries between January 2016 and February 2020. Patients were stratified into CS and non-CS groups. Primary outcomes were mortality and rehospitalization due to heart failure. Secondary outcomes were acute procedural success, functional improvement, and MR reduction. Multivariable Cox regression analysis evaluated association of CS with clinical outcomes. RESULTS: Among 93 patients analyzed (age 70.3 ± 10.2 years), 50 patients (53.8%) experienced CS before PMVR. Mortality at 30 days (10% CS vs. 2.3% non-CS; p = .212) did not differ between groups. After median follow-up of 7 months (IQR 2.5-17 months), the combined event mortality/re-hospitalization was similar (28% CS vs. 25.6% non-CS; p = .793). Likewise, immediate procedural success (90% CS vs. 93% non-CS; p = .793) and need for reintervention (CS 6% vs. non-CS 2.3%, p = .621) or re-admission due to HF (CS 13% vs. NCS 23%, p = .253) at 3 months did not differ. CS was not independently associated with the combined end-point (hazard ratio 1.1; 95% CI, 0.3-4.6; p = .889). CONCLUSIONS: Patients found to have significant MR during their index hospitalization for AMI had similar clinical outcomes with PMVR whether they presented in or out of cardiogenic shock, provided initial hemodynamic stabilization was first achieved before PMVR.

RESUMO

BACKGROUND: Anti-endothelial cell antibodies (AECA) are a known biomarker of endothelial dysfunction and damage in clinical practice, especially in autoimmune disease. OBJECTIVES: To determine the relation between natural AECA levels and prognosis related to coronary artery disease. METHODS: Candidates for coronary angiography were prospectively enrolled. AECA levels were determined by ELISA assay. Mortality was evaluated after more than 5 years follow-up. RESULTS: Of a total 857 patients, 445 had high AECA levels (group 1) and 412 had low levels (< 1 OD unit, group 2). Both groups did not differ in age, sex, or presence of diabetes. The median follow up was 2293 days (76 months). Patients with high AECA levels were more likely to have normal coronary arteries on angiography (21.6% vs. 16.9%, P = 0.047) and less likely to have calcified lesions (19.0% vs. 26.6%, P = 0.028) and lower prevalence of abnormal renal functions (71.1 mg/dl vs. 66.5 mg/dl, P = 0.033). Patients with higher AECA levels had lower mortality levels (20.1% vs. 27.6%, P = 0.006). A logistic regression model demonstrated independent association between lower AECA levels and the presence of coronary atherosclerosis based on angiogram. CONCLUSIONS: After a median of more than 6 years, higher natural AECA levels were associated with less coronary artery disease and lower mortality rates in patients undergoing coronary angiography.

RESUMO

BACKGROUND: Chronic kidney disease (CKD) is associated with poorer outcomes following percutaneous coronary intervention (PCI) with drug-eluting stents. Drug-eluting balloons are used for in-stent restenosis and selected cases of de-novo coronary lesions. Little is known regarding the outcomes of individuals with CKD who undergo PCI with drug-eluting balloons. The goal of this study was to assess outcomes of PCI with drug-eluting balloons in individuals with CKD. METHODS: In a retrospective analysis, outcomes of PCI with drug-eluting balloons were compared between 101 patients with CKD and 261 without CKD. CKD was defined as estimated glomerular filtration rate < 60 ml/min/1.73m2. We compared demographics, procedure data and clinical outcomes in the first and second years following the procedure. RESULTS: Rates of major adverse cardiac events (MACE) and myocardial infarction were higher in patients with than without CKD: 23.8% vs. 13.8%, P < 0.005 and 15.9% vs. 3.8%, P < 0.001, respectively. Rates of target lesion revascularization were similar, 14.9 and 11.5%, respectively, P = 0.4. Shorter duration of dual anti-platelet therapy was observed among patients with than without CKD (10.0 + 3.4 vs. 10.9 + 3.7 months, P < 0.05). First-year hemorrhage episodes were similar in the two groups (0.08 ± 0.4 and 0.03 ± 0.2, respectively, P = 0.2). In a multivariate regression analysis, CKD was associated with increased risks of first year MACE (OR 2.1; 95% confidence interval 1.0-4.3, P < 0.001). CONCLUSIONS: PCI with drug-eluting balloons was associated with increased cardiovascular morbidity and mortality in patients with than without CKD. However, rates of target lesion revascularization were similar in the two groups. Shorter duration of dual anti-platelet therapy was observed in the CKD group.

RESUMO

BACKGROUND: Chronic kidney disease (CKD) is associated with an increased risk of adverse cardiovascular outcomes, in patients with coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI). However, most studies used bare-metal stents or first-generation drug-eluting stents, and less guideline-directed therapy to reduce cardiovascular risk was reported in CKD patients. This study investigates the impact of moderate-CKD on patients undergoing PCI in the current era. METHODS: Patient level data were pooled from 2 multicenter randomized trials (BIONICS and NIREUS trials) with a near "all-comers" design, comparing PCI with ridaforolimus-eluting stents vs. zotarolimus-eluting stents in patients with CAD. Patients were classified according to the presence or absence of moderate-CKD, defined as creatinine clearance (CrCl) <60 mL/min. We compared baseline characteristics, angiographic findings, and clinical outcomes 1-year post-PCI. RESULTS: 236/2,201 (10.7%) patients had CKD, mean CrCl of 50.3 + 7.8 mL/min. These patients were generally older and more often with hypertension than non-CKD patients, but the use of guideline-directed therapy was similar between the groups. CKD was associated with an increased risk of cardiovascular death (hazard ratio [HR] 6.08; 95% CI 2.11-17.51; p < 0.001), but with a reduced occurrence of repeated revascularization, including ischemia-driven revascularization (HR 0.47; 95% CI 0.24-0.92; p < 0.05). The rate of repeated angiography per severe cardiovascular adverse event was significantly lower in the CKD than the non-CKD group (23/38 [61%] vs. 253/334 [76%], p < 0.05). CONCLUSIONS: Moderate-CKD in patients with CAD was associated with higher rates of all-cause and cardiovascular mortality, yet with a lower risk of revascularization 1-year following PCI. Lack of guideline-directed medical therapy does not explain the adverse outcome of CKD patients.

RESUMO

Transcatheter heart valve (THV) procedures require careful planning and consideration to prevent coronary artery obstruction (CAO), which poses a significant and potentially life-threatening condition, especially in patients undergoing valve-in-valve (ViV) transcatheter aortic valve replacement (TAVR). Despite identifying predictors of CAO and utilization of computed tomography and inputting THV features, a significant uncertainty remains in predicting CAO. The ShortCut™ device (Pi-Cardia, Rehovot, Israel) was purposefully designed to modify the leaflets in patients undergoing TAVR, especially prior to ViV procedures, to overcome the risk for CAO. This review aims to detail the device's objectives, structure, procedural steps, the available clinical data, and future directions for its intended utilization in the structural arena for the prevention of CAO.

RESUMO

Spontaneous coronary artery dissection (SCAD) is a rare cause of ST-segment elevation myocardial infarction (STEMI), predominantly affecting women. Because primary percutaneous coronary intervention (PPCI) is reserved for a select group of patients, vulnerable and minority patients may experience delays in appropriate management and adverse outcomes. We examined the racial differences in the outcomes for patients with SCAD who underwent PPCI for STEMI. Records of patients aged ≥18 years who underwent PPCI for SCAD-related STEMI between 2016 and 2020 were identified from the National Inpatient Sample database. Clinical, socioeconomic, and hospital characteristics were compared between non-White and White patients. Weighted multivariate analysis assessed the association of race with inpatient mortality, length of stay (LOS), and hospitalization costs. The total weighted estimate of patients with SCAD-STEMI who underwent PPCI was 4,945, constituting 25% non-White patients. Non-White patients were younger (56 vs 60.7 years, p <0.001); had a higher prevalence of diabetes, acute renal failure, and obesity; and were more likely to be uninsured and be in the lowest income group. Inpatient mortality (7.7% vs 8.4%, p = 0.74) and hospitalization costs ($34,213 vs $31,858, p = 0.27) were similar for non-White and White patients, and the adjusted analysis did not show any association between the patients' race and inpatient mortality (odds ratio 0.60, 95% confidence interval [CI] 0.32 to 1.13, p = 0.11) or hospitalization costs (ß [ß coefficient]: 215, 95% CI -4,193 to 4,623, p >0.90). Similarly, there was no association between the patients' race and LOS (incident rate ratio 1.20, 95% CI 1.00 to 1.45, p = 0.054). The weighted multivariate analysis showed that age; clinical co-morbidities such as diabetes, acute renal failure, valvular dysfunction, and obesity; low-income status; and hospitalization in the western region were associated with adverse outcomes. In conclusion, our study does not show any differences in inpatient mortality, LOS, and hospitalization costs between non-White and White patients who underwent PPCI for SCAD-related STEMI.

RESUMO

AIMS: Acute mitral regurgitation (MR) in the setting of myocardial infarction (MI) may be the result of papillary muscle rupture (PMR). This condition is associated with high morbidity and mortality. We aim to evaluate the feasibility of transcatheter edge-to-edge mitral valve repair (TEER) in this acute setting. METHODS AND RESULTS: We analysed data from the International Registry of MitraClip in Acute Mitral Regurgitation following acute Myocardial Infarction (IREMMI) of 30 centres in Europe, North America, and the middle east. We included patients with post-MI PMR treated with TEER as a salvage procedure, and we evaluated immediate and 30-day outcomes. Twenty-three patients were included in this analysis (9 patients suffered complete papillary muscle rupture, 9 partial and 5 chordal rupture). The patients' mean age was 68 ± 14 years. Patients were at high surgical risk with median EuroSCORE II 27% (IQR 16, 28) and 20 out of 23 (87% were in cardiogenic shock). All patients were treated with vasopressors, and 17 out of 23 patients required mechanical support. TEER procedure was performed on the median 6 days after the index MI date IQR (3, 11). Procedural success was achieved in 87% of patients. The grade of MR was significantly decreased after the procedure. MR reduction to 0 or 1 + was achieved in 13 patients (57%), to 2 + in 7 patients (30%), P < 0.01. V-Wave was reduced from 49 ± 8 mmHg to 26 ± 10 mmHg post-procedure, P < 0.01. Sixteen out of 23 patients (70%) were discharged from hospital and 5 of them required reintervention with surgical mitral valve replacement. No additional death at 1 year was documented. CONCLUSIONS: TEER is a feasible therapy in critically ill patients with PMR due to a recent MI. TEER may have a role as salvage treatment or bridge to surgery in this population.

RESUMO

BACKGROUND: PROTECT IV is a current enrolling randomized controlled trial evaluating high-risk percutaneous coronary intervention (HR-PCI) with prophylactic Impella versus no Impella to reduce the composite primary endpoint of all-cause death, stroke, myocardial infarction (MI), or cardiovascular hospitalization. In a PROTECT IV-like cohort of patients who underwent HR-PCI without Impella, we aimed to report the rate of major adverse events to determine whether the trial is adequately powered. METHODS AND RESULTS: A total of 700 patients meeting similar inclusion/exclusion criteria of PROTECT IV who underwent HR-PCI without Impella at a single tertiary center from 2008 to 2022 were included in the analysis. The composite rates of all-cause death, MI, target lesion revascularization, and target vessel revascularization at 1, 2, and 3 years were estimated using the Kaplan-Meier method, and the results were used to calculate the sample size under the constant hazard ratio assumption and expected number of events to be observed used in planning PROTECT IV. The primary endpoint occurred in 30.8 % of patients at 2 years. PROTECT IV assumes a hazard ratio of 0.75 using a multivariate Cox regression, which, under a 5 % level and 90 % power, yields 516 events. This implies a 2-year primary outcome rate of 50 % for the non-Impella arm. CONCLUSION: Therefore, PROTECT IV estimates that a sample size of 1252 patients is required for Impella to be declared superior to the non-Impella group. Using our observed 2-year outcome of 30.8 %, we estimate that PROTECT IV requires 1966 patients, demonstrating that PROTECT IV is probably underpowered.

RESUMO

Bioprosthetic aortic valve thrombosis is frequently detected after transcatheter and surgical aortic valve replacement due to advances in cardiac computed tomography angiography technology and standardized surveillance protocols in low-surgical-risk transcatheter aortic valve replacement trials. However, evidence is limited concerning whether subclinical leaflet thrombosis leads to clinical adverse events or premature structural valve deterioration. Furthermore, there may be net harm in the form of bleeding from aggressive antithrombotic treatment in patients with subclinical leaflet thrombosis. This review will discuss the incidence, mechanisms, diagnosis, and optimal management of bioprosthetic aortic valve thrombosis after transcatheter aortic valve replacement and bioprosthetic surgical aortic valve replacement.
