Abstract
Coronary artery obstruction is a rare complication of transcatheter aortic valve replacement (TAVR). This risk increases in TAVR-valve-in-valve procedure. Several anatomic risk factors were described in many studies to identify the predictive elements of coronary artery occlusion on computed tomography cardiac scan. Rescue percutaneous coronary intervention was the first approach described to treat this complication with a high mortality rate. Later on, preventive chimney stenting technique was evaluated and results showed that is a safe and effective strategy but it leads to a difficult coronary access later. New preventive techniques are being evaluated recently (Basilica and Shorctut).

Computational study of transcatheter aortic valve replacement based on patient-specific models-rapid surgical planning for self-expanding valves. Front Physiol 2024; 15:1407215.

Abstract
Transcatheter aortic valve replacement (TAVR) is a minimally invasive interventional solution for treating aortic stenosis. The complex post-TAVR complications are associated with the type of valve implanted and the position of the implantation. The study aimed to establish a rapid numerical research method for TAVR to assess the performance differences of self-expanding valves released at various positions. It also aimed to calculate the risks of postoperative paravalvular leak and atrioventricular conduction block, comparing these risks to clinical outcomes to verify the method's effectiveness and accuracy. Based on medical images, six cases were established, including the aortic wall, native valve and calcification; one with a bicuspid aortic valve and five with tricuspid aortic valves. The parameters for the stent materials used by the patients were customized. High strain in the contact area between the stent and the valve annulus may lead to atrioventricular conduction block. Postoperatively, the self-expanding valve maintained a circular cross-section, reducing the risk of paravalvular leak and demonstrating favorable hemodynamic characteristics, consistent with clinical observations. The outcomes of the six simulations showed no significant difference in valve frame morphology or paravalvular leak risk compared to clinical results, thereby validating the numerical simulation process proposed for quickly selecting valve models and optimal release positions, aiding in TAVR preoperative planning based on patients'geometric characteristics.

Abstract
Cardiac Computed Tomography (CCT) has become a reliable imaging modality in cardiology providing robust information on the morphology and structure of the heart with high temporal and isotropic spatial resolution. For the past decade, there has been a paradigm shift in the management of valvular heart disease since previously unfavorable candidates for surgery are now provided with less-invasive interventions. Transcatheter heart valve interventions provide a real alternative to medical and surgical management and are often the only treatment option for valvular heart disease patients. Successful transcatheter valve interventions rely on comprehensive multimodality imaging assessment. CCT is the mainstay imaging technique for preprocedural planning of these interventions. CCT is critical in guiding patient selection, choice of procedural access, device selection, procedural guidance, as well as allowing postprocedural follow-up of complications. This article aims to review the current evidence of the role of CCT in the preprocedural planning of patients undergoing transcatheter valvular interventions.

Abstract
BACKGROUND In recent years, the kidney function after Transcatheter Aortic Valve Replacement (TAVR) has gradually become a hot spot that arouse extensive attention.Our study is aimed to evaluate the incidence and predictors of acute kidney recovery (AKR) after TAVR. METHODS A total of 102 patients undergoing TAVR in Beijing Anzhen Hospital from June 2021 to March 2022 were enrolled in our study. Patients were divided into AKR group (n = 54), unchanged group (n = 40) and acute kidney injury (AKI) group (n = 8) based on the percent change of estimated glomerular filtration rate (eGFR). Univariate analysis was used to compare the differences in general clinical characteristics and other related indicators between the three groups to analyze the risk factors of AKR. RESULTS The incidence of AKR was 53% (54/102) after TAVR. Multivariate analysis showed that the incidence of age and proportion of severe NYHA class (III or IV) was significantly higher in the AKR group while renal dysfunction (eGFR <60 mL/min/1.73 m2) was lower. Besides, fluid management/volume therapy was significantly different among the three groups. CONCLUSIONS AKR is a generalizable phenomenon occurring frequently after TAVR. The age, proportion of severe NYHA class and the baseline renal function are independent predictors of AKR events in patients with severe aortic stenosis undergoing TAVR.

Abstract
Since the advent of transcatheter aortic valve replacement (TAVR) in 2002, it has now become the default interventional strategy for symptomatic patients presenting with severe aortic stenosis, particularly in intermediate to high-surgical risk patients. In 2019, the United States Food and Drug Administration approved TAVR in low-risk patients based on two randomized trials. However, these breakthrough trials excluded patients with certain unfavorable anatomies and odd profiles. While currently there is no randomized study of TAVR in young patients, it may be preferred by the young population given the benefits of early discharge, shorter hospital stay, and expedite recovery. Nonetheless, it is important to ruminate various factors including lifetime expectancy, risk of pacemaker implantation, and the need for future valve or coronary interventions in young cohorts before considering TAVR in these patients. Furthermore, the data on long-term durability (> 10 years) of TAVR is still unknown given most of the procedures were initially performed in the high or prohibitive surgical risk population. Thus, this editorial aims to highlight the importance of considering an individualized approach in young patients with consideration of various factors including lifetime expectancy while choosing TAVR against surgical aortic valve replacement.

Abstract
BACKGROUND Coronary artery obstruction after percutaneous aortic replacement is a complication with high short-term mortality secondary to the lack of timely treatment. There are various predictors of coronary obstruction prior to valve placement such as the distance from the ostia, the degree of calcification, the distance from the sinuses; In such a situation some measures must be taken to prevent and treat coronary obstruction. CASE PRESENTATION An 84-year-old male, with severe aortic stenosis and high surgical risk, who was treated with TAVR. However, during the deployment of the valve he presented hemodynamic instability secondary to LMCA obstruction. The intravascular image showed obstruction of the ostium secondary to the displacement of calcium that he was successfully treated with a chimney stent technique. CONCLUSIONS The high degree of calcification and the left ostium near the annulus are conditions for obstruction of the ostium at the time of valve release; In this context, provisional stenting prior to TAVR in patients at high risk of obstruction should be considered as a safe prevention strategy to achieve the success of the procedure.

Abstract
BACKGROUND Transcatheter Aortic Valve Implantation (TAVI) has a growing target population after being indicated even in low-surgical-risk patients with severe symptomatic aortic stenosis. However, postoperative outcomes can be compromised due to para-valvular leakage (PVL). A lot of procedural steps have been investigated to decrease this partially avoidable operational hazard. Oversizing is a main technique to decrease the PVL, despite being itself a risky step. Many studies have been conducted to identify the optimum degree of oversizing. However, studies about oversizing by more than 20% are scarce. We aimed to evaluate the safety and efficacy of oversizing equal to or more than 20%. RESULTS 209 patients who underwent TAVI using the self-expandable valve Evolut R were initially included. 66 patients were excluded because of the baseline conduction disturbance and lack of sufficient data, so 143 patients, 60 females and 83 males, were enrolled in our study as two groups based on the degree of oversizing: Group A included 97 patients with an oversizing index (OI) of less than 20%, and Group B included 46 patients with an OI of 20% or more. We conducted a new technique for more accurate measuring of the OI in the context of the implantation depth, and our patients were categorized using this technique. Our findings have met our primary end point in terms of the safety and efficacy of oversizing by 20% or more. There was no significant difference between both groups in terms of new-onset conduction disturbance (NOCD), with zero cases of annular rupture or coronary encroachment. In terms of efficacy, The incidence of significant PVL (grade 2 or more) in group B was less than in group A (P value 0.007). The ROC curve found that the minimum depth of implantation-derived oversizing (DIDO) to predict no significant PVL was less than 17%. CONCLUSION Prosthesis oversizing by 20% using the self-expandable Evolut R valve is safe and effective, with no significant effect on the conduction system, coronary encroachment, or annular injury, and warrants a greater reduction in the incidence of significant PVL.

Abstract
In silico trials are a promising way to increase the efficiency of the development, and the time to market of cardiovascular implantable devices. The development of transcatheter aortic valve implantation (TAVI) devices, could benefit from in silico trials to overcome frequently occurring complications such as paravalvular leakage and conduction problems. To be able to perform in silico TAVI trials virtual cohorts of TAVI patients are required. In a virtual cohort, individual patients are represented by computer models that usually require patient-specific aortic valve geometries. This study aimed to develop a virtual cohort generator that generates anatomically plausible, synthetic aortic valve stenosis geometries for in silico TAVI trials and allows for the selection of specific anatomical features that influence the occurrence of complications. To build the generator, a combination of non-parametrical statistical shape modeling and sampling from a copula distribution was used. The developed virtual cohort generator successfully generated synthetic aortic valve stenosis geometries that are comparable with a real cohort, and therefore, are considered as being anatomically plausible. Furthermore, we were able to select specific anatomical features with a sensitivity of around 90%. The virtual cohort generator has the potential to be used by TAVI manufacturers to test their devices. Future work will involve including calcifications to the synthetic geometries, and applying high-fidelity fluid-structure-interaction models to perform in silico trials.

Abstract
Bicuspid aortic valve (BAV) is a common congenital valvular malformation, which may lead to early aortic valve disease and bicuspid-associated aortopathy. A novel BAV classification system was recently proposed to coincide with transcatheter aortic valve replacement being increasingly considered in younger patients with symptomatic BAV, with good clinical results, yet without randomized trial evidence. Procedural technique, along with clinical outcomes, have considerably improved in BAV patients compared with tricuspid aortic stenosis patients undergoing transcatheter aortic valve replacement. The present review summarizes the novel BAV classification systems and examines contemporary surgical and transcatheter approaches.

Abstract
Acute coronary occlusion during transcatheter aortic valve implantation (TAVI) is a rare but potentially lethal complication. Main mechanisms are sinus insufficiency or sinus sequestration with well-described risk factors. We present two cases of acute right coronary artery occlusion during TAVI with a self-expanding valve in the absence of classical risk factors and propose a novel mechanism.

Abstract
PURPOSE OF REVIEW Cardiac computed tomography (CT) is an established non-invasive imaging tool for the assessment of coronary artery disease. Furthermore, it plays a key role in the preinterventional work-up of patients presenting with structural heart disease. RECENT FINDINGS CT is the gold standard for preprocedural annular assessment, device sizing, risk determination of annular injury, coronary occlusion or left ventricular outflow tract obstruction, calcification visualization and quantification of the target structure, and prediction of a co-planar fluoroscopic angulation for transcatheter interventions in patients with structural heart disease. It is further a key imaging modality in postprocedural assessment for prosthesis thrombosis, degeneration, or endocarditis. CT plays an integral part in the imaging work-up of novel transcatheter therapies for structural heart disease and postprocedural assessment for prosthesis thrombosis or endocarditis. This review provides a comprehensive overview of the key role of CT in the context of structural heart interventions.

Abstract
Periprocedural systemic embolism is a well-documented complication of transcatheter aortic valve replacement (TAVR). Although the most focus was given to cerebral embolism (which remains unpredictable, difficult to prevent, and a source of increased morbidity and mortality after TAVR), coronary embolism remains less investigated and potentially overlooked. This study provides a case series of 3 patients diagnosed with coronary embolism after TAVR in our institution over a 2-year period (3 of 297 cases, 1%) and a systematic literature review (4 studies; 19 case reports). Overall, coronary embolism associated with TAVR is frequently characterized by proximal vessel occlusion causing ST-elevation myocardial infarction and hemodynamic instability with lower mortality in the acute phase as compared with late coronary embolism. However, it often presents with distal vessel occlusion and minor symptoms that may be overlooked in the periprocedural period. In conclusion, we suggest that TAVR-associated coronary embolism has a much higher prevalence than previously documented. Further studies are warranted to properly assess the prevalence and impact of this phenomenon.

Abstract
Myocardial infarction with nonobstructive coronary arteries (MINOCA) is a distinct subtype of myocardial infarction (MI), occurring in about 8-10% of spontaneous MI cases referred for coronary angiography. Unlike MI with obstructive coronary artery disease, MINOCA's pathogenesis is more intricate and heterogeneous, involving mechanisms such as coronary thromboembolism, coronary vasospasm, microvascular dysfunction, dissection, or plaque rupture. Diagnosing MINOCA presents challenges and includes invasive and non-invasive strategies aiming to differentiate it from alternative diagnoses and confirm the criteria of elevated cardiac biomarkers, non-obstructive coronary arteries, and the absence of alternate explanations for the acute presentation. Tailored management strategies for MINOCA hinge on identifying the underlying cause of the infarction, necessitating systematic diagnostic approaches. Furthermore, determining the optimal post-MINOCA medication regimen remains uncertain. This review aims to comprehensively address the current state of knowledge, encompassing diagnostic and therapeutic approaches, in the context of MINOCA while also highlighting the evolving landscape and future directions for advancing our understanding and management of this intricate myocardial infarction subtype.

Abstract
Surgical aortic valve replacement (SAVR) has long been the standard treatment for severe symptomatic aortic stenosis (AS). However, transcatheter aortic valve replacement (TAVR) has emerged as a minimally invasive alternative; it was initially intended for high-risk patients and has now expanded its use to patients of all risk groups. While TAVR has demonstrated promising outcomes in diverse patient populations, uncertainties persist regarding its long-term durability and potential complications, raising the issue of the ideal lifetime management strategy for patients with AS. Therefore, SAVR continues to play an important role in clinical practice, particularly in younger patients with longer life expectancies, those with complex aortic anatomy who are unsuitable for TAVR, and those requiring concomitant surgical procedures. The choice between TAVR and SAVR warrants personalized decision-making, considering patient characteristics, comorbidities, anatomical considerations, and overall life expectancy. A multidisciplinary approach involving an experienced heart team is crucial in the preoperative evaluation process. In this review, we aimed to explore the current role of surgical management in addressing aortic valve stenosis amidst the expanding utilization of less invasive transcatheter procedures.

Intracoronary Pacing during "Chimney Technique" in Transcatheter Aortic Valve-in-Valve Implantation: An Alternative Temporary Rapid Ventricular Stimulation? J Cardiovasc Dev Dis 2023; 10:341.

Abstract
Temporary rapid ventricular pacing (TRVP) is required during transcatheter aortic valve implantation (TAVI) in order to reduce cardiac output and to facilitate balloon aortic valvuloplasty, prosthesis deployment, and post-deployment balloon dilation. The two most frequently used TRVP techniques are right endocardial (RE)-TRVP and retrograde left endocardial temporary rapid ventricular pacing (RLE)-TRVP. The first one could be responsible for cardiac tamponade, one of the most serious procedural complications during TAVI, while the second one could often be unsuccessful. Intracoronary (IC)-TRVP through a coronary guidewire has been described as a safe and efficient procedure that could avoid such complications. We describe two clinical cases in which IC-TRVP has been effectively used during valve-in-valve TAVI with coronary protection via the "chimney technique", after unsuccessful RLE-TRVP.

Abstract
Due to technological advancements during the past 20 years, transcatheter aortic valve replacements (TAVRs) have significantly improved the treatment of symptomatic and severe aortic stenosis, significantly improving patient outcomes. The continuous evolution of transcatheter valve models, refined imaging planning for enhanced accuracy, and the growing expertise of technicians have collectively contributed to increased safety and procedural success over time. These notable advancements have expanded the scope of TAVR to include patients with lower risk profiles as it has consistently demonstrated more favorable outcomes than surgical aortic valve replacement (SAVR). As the field progresses, coronary angiography is anticipated to become increasingly prevalent among patients who have previously undergone TAVR, particularly in younger cohorts. It is worth noting that aortic stenosis is often associated with coronary artery disease. While the task of re-accessing coronary artery access following TAVR is challenging, it is generally feasible. In the context of valve-in-valve procedures, several crucial factors must be carefully considered to optimize coronary re-access. To obtain successful coronary re-access, it is essential to align the prosthesis with the native coronary ostia. As part of preventive measures, strategies have been developed to safeguard against coronary obstruction during TAVR. One such approach involves placing wires and non-deployed coronary balloons or scaffolds inside an at-risk coronary artery, a procedure known as chimney stenting. Additionally, the bioprosthetic or native aortic scallops intentional laceration to prevent iatrogenic coronary artery obstruction (BASILICA) procedure offers an effective and safer alternative to prevent coronary artery obstructions. The key objective of our study was to evaluate the techniques and procedures employed to achieve commissural alignment in TAVR, as well as to assess the efficacy and measure the impact on coronary re-access in valve-in-valve procedures.

Abstract
INTRODUCTION Small aortic annulus (SAA) poses a challenge in the management of patients with severe aortic stenosis requiring aortic valve replacement - both surgical and transcatheter - since it has been associated with worse clinical outcomes. AREAS COVERED This review aims to comprehensively summarize the available evidence regarding the management of aortic stenosis in patients with SAA and discuss the current controversies as well as future perspectives in this field. EXPERT OPINION It is paramount to agree in a common definition for diagnosing and properly treating SAA patients, and for that purpose, multidetector computer tomography is essential. The results of recent trials led to the expansion of transcatheter aortic valve replacement among patients of all the surgical-risk spectrum, and the choice of treatment (transcatheter, surgical) should be based on patient comorbidities, anatomical characteristics, and patient preferences.

Abstract
In recent years, transcatheter aortic valve replacement (TAVR) has become the leading method for treating aortic stenosis. While the procedure has improved dramatically in the past decade, there are still uncertainties about the impact of TAVR on coronary blood flow. Recent research has indicated that negative coronary events after TAVR may be partially driven by impaired coronary blood flow dynamics. Furthermore, the current technologies to rapidly obtain non-invasive coronary blood flow data are relatively limited. Herein, we present a lumped parameter computational model to simulate coronary blood flow in the main arteries as well as a series of cardiovascular hemodynamic metrics. The model was designed to only use a few inputs parameters from echocardiography, computed tomography and a sphygmomanometer. The novel computational model was then validated and applied to 19 patients undergoing TAVR to examine the impact of the procedure on coronary blood flow in the left anterior descending (LAD) artery, left circumflex (LCX) artery and right coronary artery (RCA) and various global hemodynamics metrics. Based on our findings, the changes in coronary blood flow after TAVR varied and were subject specific (37% had increased flow in all three coronary arteries, 32% had decreased flow in all coronary arteries, and 31% had both increased and decreased flow in different coronary arteries). Additionally, valvular pressure gradient, left ventricle (LV) workload and maximum LV pressure decreased by 61.5%, 4.5% and 13.0% respectively, while mean arterial pressure and cardiac output increased by 6.9% and 9.9% after TAVR. By applying this proof-of-concept computational model, a series of hemodynamic metrics were generated non-invasively which can help to better understand the individual relationships between TAVR and mean and peak coronary flow rates. In the future, tools such as these may play a vital role by providing clinicians with rapid insight into various cardiac and coronary metrics, rendering the planning for TAVR and other cardiovascular procedures more personalized.

Abstract
Delayed coronary obstruction (DCO) occurs when there is obstruction of the coronary ostia following a transcatheter aortic valvular implantation (TAVI). It is an uncommon but serious complication that often leads to death, usually presents as severe hypotension after TAVI, and should be suspected if migration of the valve occurs. We report the case of a 70-year-old female patient with severe aortic stenosis who underwent TAVI using a 26-mm CoreValve Evolut Pro (Medtronic, Dublin, Ireland). Although the valve was implanted successfully, she experienced hypotension with intermittent ST elevations and had a cardiac arrest shortly after, requiring Advanced Cardiovascular Life Support (ACLS). An aortogram showed sealing of the sinotubular junction (STJ) by CoreValve, without coronary flow. CoreValve was then snared and repositioned in the ascending aorta recovering coronary flow and cardiac pulsatility. A second TAVI was performed and an Edwards 20 mm Sapiens 3 valve (Edwards Lifesciences, Irvine, CA, USA) was implanted as standard procedure.

Abstract
BACKGROUND Coronary obstruction (CO) following transcatheter aortic valve replacement (TAVR) is a life-threatening complication, scarcely studied. OBJECTIVES The authors analyzed the incidence of CO after TAVR, presentation, management, and in-hospital and 1-year clinical outcomes in a large series of patients undergoing TAVR. METHODS Patients from the Spanish TAVI (Transcatheter Aortic Valve Implantation) registry who presented with CO in the procedure, during hospitalization or at follow-up were included. Computed tomography (CT) risk factors were assessed. In-hospital, 30-day, and 1-year all-cause mortality rates were analyzed and compared with patients without CO using logistic regression models in the overall cohort and in a propensity score-matched cohort. RESULTS Of 13,675 patients undergoing TAVR, 115 (0.80%) presented with a CO, mainly during the procedure (83.5%). The incidence of CO was stable throughout the study period (2009-2021), with a median annual rate of 0.8% (range 0.3%-1.3%). Preimplantation CT scans were available in 105 patients (91.3%). A combination of at least 2 CT-based risk factors was less frequent in native than in valve-in-valve patients (31.7% vs 78.3%; P < 0.01). Percutaneous coronary intervention was the treatment of choice in 100 patients (86.9%), with a technical success of 78.0%. In-hospital, 30-day, and 1-year mortality rates were higher in CO patients than in those without CO (37.4% vs 4.1%, 38.3% vs 4.3%, and 39.1% vs 9.1%, respectively; P < 0.001). CONCLUSIONS In this large, nationwide TAVR registry, CO was a rare, but often fatal, complication that did not decrease over time. The lack of identifiable predisposing factors in a subset of patients and the frequently challenging treatment when established may partly explain these findings.

Abstract
Introduction Transcatheter aortic valve implantation (TAVI) is a novel treatment strategy used to treat patients with symptomatic aortic stenosis. It utilizes a percutaneous approach and is preferred over surgical aortic valve replacement (SAVR) in patients at high surgical risk. The aim of this study was to audit the indications of the intervention with TAVI over SAVR in Bahrain Defence Force Hospital, Mohammed Bin Khalifa Bin Sulman AlKhalifa Cardiac Centre (BDF-MKCC), as well as note the outcomes of patients who underwent TAVI. Methods The indications for allocating aortic stenosis patients to TAVI over SAVR in BDF-MKCC were studied with regard to the European Society of Cardiology and the European Association for Cardio-Thoracic Surgery (ESC/EACTS) guidelines published in 2017. Data from 82 patients, which accounts for all patients who underwent TAVI, were collected retrospectively from electronic medical records and the percentage of compliance was calculated and analyzed. Results The compliance percentages of the 23 parameters for the intervention with TAVI that have been set by the ESC/EACTS are calculated, where BDF-MKCC were fully adherent to 12 out of the 23 standards. Moreover, the total number of patients that are compliant with all standards is 13 out of 82 (15.85%) compliant patients. Conclusion The centre showed non-compliance to many of the published standards. Hence, we created a checklist to ensure that the international guidelines are followed. We are looking forward to re-audit this aspect in the near future, to make certain that changes were done. We would also like to do a comparative study to compare the patients' outcomes before and after implementing the 2017 ESC/EACTS guidelines. Furthermore, we call for further studies to be conducted in this field and that is to evaluate the standards themselves as well as the safety of TAVI in those who are not eligible for it according to the ESC/EACTS.

Abstract
Myocardial infarction with nonobstructive coronary arteries (MINOCA) is a heterogeneous group of clinical entities characterized by clinical evidence of acute myocardial infarction (AMI) with normal or near-normal coronary arteries on coronary angiography (stenosis < 50%) and without an over the alternative diagnosis for the acute presentation. Its prevalence ranges from 6% to 11% among all patients with AMI, with a predominance of young, nonwhite females with fewer traditional risks than those with an obstructive coronary artery disease (MI-CAD). MINOCA can be due to either epicardial causes such as rupture or fissuring of unstable nonobstructive atherosclerotic plaque, coronary artery spasm, spontaneous coronary dissection and cardioembolism in-situ or microvascular causes. Besides, also type-2 AMI due to supply-demand mismatch and Takotsubo syndrome must be considered as a possible MINOCA cause. Because of the complex etiology and a limited amount of evidence, there is still some confusion around the management and treatment of these patients. Therefore, the key focus of this condition is to identify the underlying individual mechanisms to achieve patient-specific treatments. Clinical history, electrocardiogram, echocardiography, and coronary angiography represent the first-level diagnostic investigations, but coronary imaging with intravascular ultrasound and optical coherent tomography, coronary physiology testing, and cardiac magnetic resonance imaging offer additional information to understand the underlying cause of MINOCA. Although the prognosis is slightly better compared with MI-CAD patients, MINOCA is not always benign and depends on the etiopathology. This review analyzes all possible pathophysiological mechanisms that could lead to MINOCA and provides the most specific and appropriate therapeutic approach in each scenario.

Three-Year Outcomes of Balloon-Expandable Transcatheter Aortic Valve Implantation According to Annular Size. Am J Cardiol 2023; 194:9-16. [PMID: 36921423 DOI: 10.1016/j.amjcard.2023.01.051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Revised: 01/23/2023] [Accepted: 01/31/2023] [Indexed: 03/18/2023]
Abstract
Data on the association between annular size and transcatheter aortic valve implantation (TAVI) outcomes beyond 1 year are limited. The present study assessed the association between the aortic annulus size and TAVI clinical and hemodynamic outcomes at 3 years of follow-up. Patients were classified according to the aortic annulus size as having small, intermediate, and large annuli (size <400, 400 to 574, and ≥575 mm2, respectively). The co-primary endpoints were all-cause mortality and heart failure hospitalization. Further, the changes in hemodynamic outcomes over the follow-up period (median 37, interquartile range: 26 to 45 months) were assessed. The present analysis included 850 patients, with 182 patients (21.4%), 538 patients (63.3%), and 130 patients (15.3%) in the small, intermediate, and large-sized aortic annulus groups, respectively. The groups had comparable age and pre-TAVI pressure gradients; however, patients with small annuli had higher Society of Thoracic Surgeons risk scores. Adjusted Cox regression analysis showed that compared to patients with intermediate-sized annuli, patients with small and large annuli had similar all-cause mortality (hazard ratio [HR] = 1.11, 95% confidence interval [CI] 0.72 to 1.69 and HR = 0.74, 95% CI 0.48 to 1.16, respectively) and heart failure hospitalization rates (HR = 0.96, 95% CI 0.55 to 1.69 and HR = 1.26, 95% CI 0.73 to 2.17, respectively). However, patients with small annuli had consistently higher mean and peak pressure gradients and a higher risk of patient-prosthesis mismatch. The risks of moderate-to-severe regurgitation and structural valve deterioration were similar between the three groups. In conclusion, although patients with small annuli had higher transvalvular gradients, there was no significant association between the aortic annulus size and TAVI clinical outcomes at 3 years of follow-up. Future studies should compare the performance of transcatheter valve types in patients with different aortic annulus sizes.

Abstract
Transcatheter aortic valve implantation (TAVI) is now a standard procedure for the treatment of symptomatic aortic valve stenosis in many patients. In Germany, according to the annual reports from the German Institute for Quality Assurance and Transparency in Healthcare (Institut für Qualitätssicherung und Transparenz im Gesundheitswesen), the rate of serious intraprocedural complications, such as valve malpositioning or embolization, coronary obstruction, aortic dissection, annular rupture, pericardial tamponade, or severe aortic regurgitation requiring emergency cardiac surgery has decreased markedly in recent years from more than 5.5% in 2012 to 2.0% in 2019. However, with increased use, the total number of adverse events remains about 500 per year, about 100 of which require conversion to sternotomy. These, sometimes, fatal events can occur at any time and are still challenging. Therefore, the interdisciplinary TAVI heart team should be prepared and aware of possible rescue strategies.

Abstract
Since the first transcatheter delivery of an aortic valve prosthesis was performed by Cribier et al in 2002, the picture of aortic stenosis (AS) therapeutics has changed dramatically. Initiated from an indication of inoperable to high surgical risk, extending to intermediate and low risk, transcatheter aortic valve replacement (TAVR) is now an approved treatment for patients with severe, symptomatic AS across all the risk categories. The current evidence supports TAVR as a frontline therapy for treating severe AS. The crucial question remains concerning the subset of patients who still are not ideal candidates for TAVR because of certain inherent anatomic, nonmodifiable, and procedure-specific factors. Therefore, in this study, we focus on these scenarios and reasons for referring selected patients for surgical aortic valve replacement in 2023.

Abstract
Coronary artery occlusion (CAO) is a rare but life-threatening complication of transcatheter aortic valve implantation (TAVI). The mechanism of CAO is the displacement of the native calcified valve leaflet over the coronary ostium. Here, we report on a woman who experienced sudden cardiac arrest and abrupt CAO during TAVI, which was caused by two different original obstructions, a rupture of aortic plaque or a partial tear of the aortic intima blocking the upper 2/3 of the left main trunk (LMT) ostium, and the transcatheter heart valve (THV) blocking the lower 1/3 of the LMT ostium. She was eventually successfully treated with the chimney stenting technique. Aortography other than coronary angiography was used to ascertain CAO. In patients presenting with abrupt cardiac arrest or cardiogenic shock with LMT occlusion, there must be prompt identification, and the causes of CAO may be various and rare. The identification of CAO relies not only on CAG but also on aortography, especially if the locations and origins of obstructions are special. Supportive therapy with an attempt at percutaneous revascularization is necessary. Pre-procedural assessment is crucial prior to TAVI interventions. In cases with high risk of CAO, upfront coronary artery protection can be provided.

Abstract
Transcatheter aortic valve replacement (TAVR) has become increasingly common as the indications expanded to include valve-in-valve (ViV) applications and a wider patient population with lower surgical risk. Intra-operative coronary arterial occlusion remains a significant source of morbidity, particularly in ViV applications or cases with high-risk anatomy. We present a novel technique for coronary artery protection utilizing a guide extension catheter to secure coronary access during valve deployment and a ViV case demonstration in a patient with prior surgical aortic valve replacement.

Abstract
Valve-in-valve transcatheter aortic valve replacement (VIV-TAVR) for a degenerated surgical aortic bioprosthesis is a well-established treatment modality but carries an increased risk of coronary artery obstruction (CAO) with potentially catastrophic consequences. Both chimney stenting and leaflet modification by BASILICA (Bioprosthetic or Native Aortic Scallop Intentional Laceration to Prevent Iatrogenic Coronary Obstruction) are increasingly employed and can be highly effective means of preventing CAO. Using a case report, in which both strategies were utilized, as a platform for detailed discussion, we address the indications, contraindications, and relative merits of each technique in the prevention of CAO.

Abstract
INTRODUCTION Transcatheter aortic valve implantation (TAVI) is commonly used to treat patients with stenosed aortic valves. CT is one of the crucial steps in planning TAVI to obtain measurements of the aortic annulus to choose an appropriately sized prosthesis. Incorrect measurements can lead to patient-prosthesis mismatch and other complications. However, some patients cannot undergo ECG-gated CT with radiocontrast because of the presence of radiopaque objects in the thorax, arrhythmia, renal failure, etc. Aim: To explore supplementary methods to improve aortic annulus sizing for TAVI by extracardiac measurements. METHODS We included all patients who underwent CT as part of TAVI planning. Measurements of femoral and iliac arteries and the femoral head cross-sectional area were performed. RESULTS CT scans of 139 patients were included in this study. Sixty-three patients (45%) were males. Mean age of the female patients was 79.6 ± 7.1 years and of the male patients was 81.3 ± 6.1 years. Mean aortic annulus perimeter among female patients was 74.3 ± 6 mm (range 61.9-88.2) and 83 ± 7.9 mm among male patients (range 70.1-74.3 mm). Mean diameters of common iliac, external iliac, and common femoral arteries were 9.2 ± 1.8, 7.6 ± 1, 7.6 ± 1 mm, respectively, for females and 10.2 ± 1.8, 8.5 ± 1.3, and 8.6 ± 1.4 mm for males. Mean perimeter of the femoral head (average value of right and left femoral heads) among the female patients was 137.8 ± 6.3 mm, and among male patients was 155 ± 9.6 mm. A significant correlation was observed between the perimeter of the aortic annulus and the perimeter of the femoral head (Pearson's R2 = 0.224). The correlation between the aortic annulus perimeter and the femoral head perimeter was stronger among men than among women (Pearson's R2 = 0.66 and 0.19, respectively). CONCLUSION Femoral head diameter is associated with annulus size. This may help size the appropriate prosthesis in cases where the measurements by CT are in the border zone if corroborated by clinically driven data.

Abstract
OBJECTIVES The aim of this review was to analyze literature and provide systematic algorithm to guide decision making during TAVI procedure. BACKGROUND Transcatheter aortic valve implantation (TAVI) is growing in popularity and expanding to younger patients with lower risk profiles. Currently, there is no concise guideline on the management strategy during TAVI in patients with anomalous coronary artery (ACA) anatomy undergoing this procedure. METHODS A systematic search was conducted for relevant case reports of TAVI in patients who had confirmed ACA anatomy. Twenty-four case reports, that met the criteria for this review, were identified and included in the final study size. RESULTS TAVI was successful in 23 out of 24 cases. Half of the cases (12) described performing balloon aortic valvuloplasty (BAV) before TAVI. The majority (15) reported using angiogram Postimplantation. Only one-third of cases (8) reported performing coronary protection (with either wire, wire and stent or wire and balloon). Two-third of case reports (16/24, 67%) mentioned using Edwards SAPIEN balloon expandable transcatheter heart valves (THV). CONCLUSIONS Preprocedural diagnostic imaging tests play important role in determining the ACA anatomy and its relation to the aortic valve. BAV with simultaneous coronary arteries angiography or aortography should be performed before implantation of THV, as it could potentially predict whether the ACA would be compressed. Using at least a coronary wire for ACA protection is recommended in case there is high risk of ACA obstruction. Management strategy should be individualized when performing TAVI in patients with ACA.

Detection of left coronary ostial obstruction during transcatheter aortic valve replacement by coronary flow velocity measurement in the left main trunk by intraoperative transesophageal echocardiography. J Cardiol 2023; 81:97-104. [PMID: 36114119 DOI: 10.1016/j.jjcc.2022.08.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2022] [Revised: 07/27/2022] [Accepted: 08/09/2022] [Indexed: 11/22/2022]
Abstract
BACKGROUND Coronary obstruction is a rare but catastrophic complication of transcatheter aortic valve replacement (TAVR) and occurs mostly at the left coronary artery (LCA) ostium. However, some patients do not show any clinical findings, and thus, its detection is sometimes difficult. The peak diastolic flow velocity in left main coronary artery (LM) was reportedly increased in significant stenosis lesions. We evaluated the effectiveness of measuring blood flow velocities in LM by transesophageal echocardiography (TEE) for the detection of LCA ostial obstruction during a TAVR procedure. METHODS A total of 1105 consecutive patients who underwent TAVR in Sendai Kousei Hospital between September 2014 and December 2020 were enrolled. The LM blood flow velocity was measured at pre- and post-valve implantation. RESULTS Among the 1105 patients, 9 had LCA ostial obstruction. The peak LM blood flow velocity at post-TAVR [0.90 (0.39-1.15) vs. 0.37 (0.28-0.50) m/s; p = 0.0046) was significantly higher in 9 patients who had LCA ostial obstruction, compared with the remaining 1096 patients who had not (controls), although no significant difference was observed before the TAVR procedures between the two groups. The post- to pre-TAVR LM flow velocity ratio [2.26 (1.31-3.42) vs. 1.06 (0.82-1.36); p = 0.0030] was also significantly higher in patients with LCA obstruction, compared to the controls. Furthermore, the post- to pre-TAVR LM blood flow velocity ratio was >2.0 in all six hemodynamically stable patients with LCA obstruction, whereas <2.0 in all three patients with LCA obstruction who showed hemodynamic collapse at post-TAVR procedure. CONCLUSION Coronary blood flow velocity in LM significantly increased in hemodynamically stable LCA obstruction patients. The intraprocedural TEE measurement of the LM flow velocities would be potentially useful to detect asymptomatic and hemodynamically stable LCA ostial obstruction.

Abstract
Transcatheter aortic valve replacement (TAVR) in the setting of an anomalous left circumflex coronary artery (LCX) has had a variety of outcomes. Most commonly an anomalous LCX originates as a separate ostium arising from the right coronary sinus or is found branching off of the proximal right coronary artery. The artery courses around the aortic annulus before taking the course seen in typical anatomy. Given this deviation from typical anatomy and increased aortic annulus pressure by the replacement valve, there is an increased risk of a complication such as acute coronary artery occlusion. Special consideration and preparation are needed to prevent adverse outcomes, including death. We report a case in which intraprocedural anomalous LCX rescue stenting proved to be effective for treatment of acute coronary occlusion. Follow-up angiography provided an opportunity to demonstrate long-term patency in rescue stenting during TAVR.

Acute left main coronary occlusion after transcatheter aortic valve implantation: life-saving intervention using the snare technique-a case report. Eur Heart J Case Rep 2022; 7:ytac469.

Abstract
Background Transcatheter aortic valve implantation (TAVI) has rapidly evolved and changed the field of structural cardiovascular intervention. Its advances lead to a marked reduction in the risk of complications and improved outcomes. However, TAVI is still associated with potential serious complications. Case summary A 73-year-old man with severe aortic stenosis underwent TAVI using a 34-mm self-expanding aortic bioprosthesis. After valve deployment, the patient rapidly progressed to cardiac arrest. Acute left main occlusion, due to high valve implantation, was promptly recognized and advanced life support immediately initiated. Concomitantly, the valve was successfully retrieved toward the ascending aorta using the snare technique, resulting in immediate restoration of flow and successful cardiopulmonary resuscitation. Subsequently, a 29-mm balloon-expandable aortic bioprosthesis was uneventfully implanted. After TAVI, the patient had a remarkable clinical evolution and was discharged home at hospitalization day five without relevant electrocardiographic nor echocardiographic disturbances. At six-month follow-up, the patient remains asymptomatic and transthoracic echocardiography revealed a normofunctional aortic bioprosthesis with preserved left ventricular ejection fraction. Discussion Acute coronary occlusion is a rare and life-threating complication of TAVI that may be prevented with accurate procedure planning. Pre-procedural computed tomography angiography is essential for a comprehensive patient evaluation, allowing appropriate valve selection, a key factor for successful management. Self-expandable valve retrieval with snare technique can be an appropriate strategy for the management of this complication. This case highlights the importance of performing these procedures in highly experienced centres and with fully equipped catheterization laboratories to allow timely interventions when facing unexpected events.

Abstract
Since the first groundbreaking procedure in 2002, transcatheter aortic valve implantation (TAVI) has revolutionized the management of aortic stenosis (AS). Through striking developments in pertinent equipment and techniques, TAVI has now become the leading therapeutic strategy for aortic valve replacement in patients with severe symptomatic AS. The procedure streamlining from routine use of conscious sedation to a single arterial access approach, the newly adapted implantation techniques, and the introduction of novel technologies such as intravascular lithotripsy and the refinement of valve-bioprosthesis devices along with the accumulating experience have resulted in a dramatic reduction of complications and have improved associated outcomes that are now considered comparable or even superior to surgical aortic valve replacement (SAVR). These advances have opened the road to the use of TAVI in younger and lower-risk patients and up-to-date data from landmark studies have now established the outstanding efficacy and safety of TAVI in patients with low-surgical risk impelling the most recent ESC guidelines to propose TAVI, as the main therapeutic strategy for patients with AS aged 75 years or older. In this article, we aim to summarize the most recent advances and the current clinical aspects involving the use of TAVI, and we also attempt to highlight impending concerns that need to be further addressed.

Abstract
Structural valvular interventions have skyrocketed in the past decade with new devices becoming available and indications for patients who would previously have been deemed inoperable. Furthermore, while echocardiography is the main imaging tool and the first line for patient screening, cardiac magnetic resonance and CT are now essential tools in pre-planning and post-procedural follow-up. This review aims to address imaging modalities and their scope in aortic, mitral and tricuspid structural valvular interventions, including multimodality imaging. Pulmonary valve procedures, which are mostly carried out in patients with congenital problems, are discussed. This article presents a guide on individualised imaging approcahes on each of the available interventional procedures.

Abstract
Transcatheter aortic valve replacement is now indicated across all risk categories of patients with symptomatic severe aortic stenosis and has been proposed as first line option for the majority of patients >74 years old. However, median age of patients enrolled in the transcatheter aortic valve replacement low-risk trials is 74 years and transcatheter aortic valve replacement has never been systematically investigated in young low risk patients. Although the long-term data in surgical aortic valve replacement in young patients (age <75) are well known, such data remain lacking in transcatheter aortic valve replacement. In the absence of clear guideline recommendations in patients with challenging anatomies (eg, hostile calcium, bicuspid), it is important to know the potential advantages and disadvantages of each treatment and to consider how they might integrate with each other in the lifetime management of such patients. In this review, we discuss current outstanding issues on the management of severe aortic stenosis from a lifetime management perspective, particularly in terms of initial intervention and future reinterventions.

Abstract
Background This study compared the clinical outcomes of transcatheter (TAVR) and surgical (SAVR) aortic valve replacements, focusing on postoperative valvular performance assessed by echocardiography. Method and Results A total of 425 patients who underwent TAVR (230 patients) or SAVR (195 patients) were included. Postoperative effective orifice area index (EOAI) was higher in the TAVR group (1.27 ± 0.35 cm2/m2) than in the SAVR group (1.06 ± 0.27 cm2/m2, p < 0.001), and patient−prosthesis mismatch (PPM) was more frequent in the SAVR group (22.6%) than in the TAVR group (8.7%, p < 0.001). Mild or greater paravalvular leakage (PVL) was more frequent in the TAVR group (21.3%) than in the SAVR group (0%, p < 0.001). Moreover, there was no difference in freedom from all-cause death, stroke, or rehospitalization between the groups. Patients with moderate or greater PPM (EOAI < 0.85 cm2/m2) had lower freedom from composite events than those without this PPM criterion (p = 0.008). Patients with mild or greater PVL also had lower freedom from composite events than those without this PVL criterion (p = 0.017). Conclusions Postoperative valvular performance of TAVR was superior to that of SAVR in terms of EOAI. This merit was counterbalanced by the significantly lower rates of PVL in patients who underwent SAVR. The overall clinical outcomes were similar between the study groups.

Abstract
OBJECTIVES With the extended indications of transcatheter aortic valve (TAV) replacement (TAVR) to lower-risk patients, there is an increasing number of patients requiring surgical explantation of failed TAV. We sought to describe macroscopic and microscopic features of surgically explanted percutaneous aortic valve prostheses. METHODS Preoperative and surgical characteristic of patients undergoing surgical explantation of TAV were retrospectively analyzed from 2007 to 2020. Surgical and pathologic features of these valves, and outcomes of the surgical valve replacement were described. RESULTS Out of 1764 patients who underwent a TAVR procedure, 21 were operated for TAV failure. Isolated or combined indications for surgery included: significant paravalvular leak (n = 15), delayed prosthesis migration (n = 5), significant increase of trans-TAV gradients (n = 6), and endocarditis (n = 3). Mean time elapsed between TAVR and explantations was 674.9 ± 803.9 days. Macroscopic lesions found on explanted percutaneous valves were severe adhesions to the aorta (n = 10), calcifications (n = 7), leaflet thrombosis (n = 4), and vegetations (n = 3). Except for patients with endocarditis, one or more pathological lesions were found in 15 patients. Pathology analyses on these valves showed fibro-calcific degenerations (n = 12), pannus formation (n = 9), and chronic inflammation (n = 3). One patient (4.8%) died after surgical explantation, and 13 (61.9%) had concomitant procedures. The survival rate at 1 year was 94.4%. CONCLUSIONS Microscopic findings of fibro-calcific leaflet degeneration, and pannus formation in addition to macroscopic calcification and thrombosis present early, (within a mean of 2 years) after TAVR. Further investigation with a higher number of patients and echocardiographic follow-up is warranted.

Abstract
We present a rare case of delayed coronary artery obstruction following a transcatheter aortic valve replacement (TAVR). Interestingly, the patient did not meet the criteria for traditionally recognized risk factors for delayed coronary obstruction. This case piques interest as to whether the severity of calcification on aortic valve leaflets plays any role in coronary obstruction post transcatheter aortic valve replacement. There is no consensus as to the optimal approach to investigation and revascularization in patients with delayed coronary obstruction. We report a case with successful emergent revascularization of the left main coronary artery following transcatheter aortic valve replacement.

Abstract
INTRODUCTION Although transcatheter aortic valve implantation (TAVI) has become a streamlined and standardized procedure, different complications still remain and need the operators to be properly trained about their management. AREAS COVERED This review article aims at offering a practical overview of the most impactful TAVI complications, analyzing, and discussing the potential risk factors, and focusing on the available strategies for their management. EXPERT OPINION Complications following TAVI have been decreasing thanks to technical advancements and operators experience. The thorough knowledge of potential complications and their prevention played a key role in the decreasing of complications rates. Pre-procedural, computed tomography angiography assessment of patient's anatomical characteristics, allows to properly choose and tailor the best strategy for managing complications in most of cases. Nevertheless, further research is required to shed lights about the optimal strategies to adopt for managing TAVI complications.

Abstract
Aortic insufficiency caused by paravalvular leakage (PVL) is one of the most feared complications following transcatheter aortic valve replacement (TAVI) in patients. Domestic pigs (Sus scrofa domestica) are a popular large animal model to study such conditions and develop novel diagnostic and therapeutic techniques. However, the models based on prosthetic valve implantation are time intensive, costly, and often hamper further hemodynamic measurements such as PV loop and 4D MRI flow by causing implantation-related wall motion abnormalities and degradation of MR image quality. This study describes in detail, the establishment of a minimally invasive porcine model suitable to study the effects of mild-to-moderate “paravalvular“ aortic regurgitation on left ventricular (LV) performance and blood flow patterns, particularly under the influence of altered afterload, preload, inotropic state, and heart rate. Six domestic pigs (Swiss large white, female, 60–70 kg of body weight) were used to establish this model. The defects on the hinge point of aortic leaflets and annulus were created percutaneously by the pierce-and-dilate technique either in the right coronary cusp (RCC) or in the non-coronary cusp (NCC). The hemodynamic changes as well as LV performance were recorded by PV loop measurements, while blood flow patterns were assessed by 4D MRI. LV performance was additionally challenged by pharmaceutically altering cardiac inotropy, chronotropy, and afterload. The presented work aims to elaborate the dos and don'ts in porcine models of aortic insufficiency and intends to steepen the learning curve for researchers planning to use this or similar models by giving valuable insights ranging from animal selection to vascular access choices, placement of PV Loop catheter, improvement of PV loop data acquisition and post-processing and finally the induction of paravalvular regurgitation of the aortic valve by a standardized and reproducible balloon induced defect in a precisely targeted region of the aortic valve.

Abstract
The transcatheter aortic valve replacement procedure is used in patients with aortic stenosis. Transcatheter aortic valve replacement devices are quite versatile; thus, they are increasingly being used for nonaortic applications, such as tricuspid valve-in-valve implantation. This case series describes a transcatheter aortic valve replacement procedure in 4 patients with anatomic challenges (eg, aortic tortuosity, high valvular calcium burden, highly calcified bicuspid valve, low coronary artery takeoff, left main coronary artery occlusion, and large aortic annulus) and a fifth patient who had a failed tricuspid bioprosthesis and underwent a tricuspid valve-in-valve implantation with the Edwards SAPIEN 3 transcatheter heart valve (Edwards Lifesciences). All procedures required adjustments to the standard protocol, and each procedure was successful. The critical, technical adjustments in the deployment technique and preprocedural planning of the procedures are detailed to provide a road map for other cardiologists who encounter similar challenges.

Abstract
BackgroundCoronary occlusion is an uncommon but fatal complication of transcatheter aortic valve replacement (TAVR) with a poor prognosis.Case PresentationA patient with symptomatic severe bicuspid aortic valve stenosis was admitted to a high-volume center specializing in transfemoral TAVR with self-expanding valves. No anatomical risk factors of coronary occlusion were identified on pre-procedural computed tomography analysis. The patient was scheduled for a transfemoral TAVR with a self-expanding valve. Balloon pre-dilatation prior to prosthesis implantation was routinely used for assessing the supra-annular structure and assessing the risk of coronary occlusion. Immediately after the tubular balloon inflation, fluoroscopy revealed that the right coronary artery was not visible, and the flow in the left coronary artery was reduced. The patient would be at high-risk of coronary occlusion if a long stent self-expanding valve was implanted. Therefore, our heart team decided to suspend the ongoing procedure. A transapical TAVR with a 23 mm J-valve was performed 3 days later. The prosthesis was deployed at a proper position without blocking the coronary ostia and the final fluoroscopy showed normal flow in bilateral coronary arteries with the same filling as preoperatively.DiscussionOur successful case highlights the importance of a comprehensive assessment of coronary risk and a thorough understanding of the TAVR procedure for the heart team. A short-stent prosthesis is feasible for patients at high risk of coronary occlusion. Most importantly TAVR should be called off even if the catheter has been introduced when an extremely high risk of coronary obstruction is identified during the procedure and no solution can be found.

Acute Coronary Artery Occlusion during Transcatheter Aortic Valve Replacement in a Patient with an Anomalous Left Circumflex Coronary Artery. Case Rep Cardiol 2022; 2022:6257367. [PMID: 35845176 PMCID: PMC9286928 DOI: 10.1155/2022/6257367] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2022] [Accepted: 06/27/2022] [Indexed: 12/03/2022] Open
Abstract
Background Acute coronary artery occlusion (CAO) during transcatheter aortic valve replacement (TAVR) is a rare but life-threatening complication during the procedure; there were a few case reports about an anomalous LCX during perioperative period. We report a case of successful coronary protection using the chimney stenting technique in a patient with a severely calcified aortic valve and an anomalous LCX. Case Summary. A 75-year-old man was found an anomalous left circumflex coronary artery (LCX) originating from the right coronary cusp with severely calcified aortic valve stenosis requiring TAVR. When a self-expanding aortic valve was deployed, we found flow compromise in the right coronary system and circumflex to TIMI-0 flow. By using the chimney stenting technique, we rapidly planted 2 stents from the proximal CX branch to the sinotubular junction and the coronary flow was maintained. Conclusion Chimney stenting protection as a bailout technique is safe and feasible and should be considered in patients deemed to be at high risk of coronary flow compromise, especially with an anomalous LCX.
