Normal-Flow Low-Gradient Aortic Stenosis: Comparing the U.S. and European Guidelines.

Patients with normal-flow low-gradient (NFLG) severe aortic stenosis present both diagnostic and management challenges, with debate about the whether this represents true severe stenosis and the need for valve replacement. Studies exploring the natural history without intervention have shown similar outcomes of patients with NFLG severe aortic stenosis to those with moderate aortic stenosis and better outcomes after valve replacement than those with low-flow low-gradient severe aortic stenosis. Most studies (all observational) have shown that aortic valve replacement was associated with a survival benefit vs surveillance. Based on available data, the European Society of Cardiology/European Association for Cardio-Thoracic Surgery guidelines and European Association of Cardiovascular Imaging/American Society of Echocardiography suggest that these patients are more likely to have moderate aortic stenosis. This clinical entity is not mentioned in the American Heart Association/American College of Cardiology guidelines. Here we review the definition of NFLG severe aortic stenosis, potential diagnostic algorithms and points of error, the data supporting different management strategies, and the differing guidelines and outline the unanswered questions in the diagnosis and management of these challenging patients.

Network Meta-Analysis Comparing the Short- and Long-Term Outcomes of Alternative Access for Transcatheter Aortic Valve Replacement.

BACKGROUND: Several studies have pair-wise compared access sites for transcatheter aortic valve replacement (TAVR) but pooled estimate of overall comparative efficacy and safety outcomes are not well known. We sought to compare short- and long-term outcomes following various alternative access routes for TAVR. METHODS: Thirty-four studies with a pooled sample size of 32,756 patients were selected by searching PubMed and Cochrane library databases from inception through 11th June 2021 for patients undergoing TAVR via 1 of 6 different access sites: Transfemoral (TF), Transaortic (TAO), Transapical (TA), Transcarotid (TC), Transaxillary/Subclavian (TSA), and Transcaval (TCV). Data were extracted to conduct a frequentist network meta-analysis with a random-effects model using TF access as a reference group. RESULTS: Compared with TF, both TAO [RR 1.91, 95% CI (1.46-2.50)] and TA access [RR 2.12, 95% CI (1.84-2.46)] were associated with an increased risk of 30-day mortality. No significant difference was observed for stroke, myocardial infarction, major bleeding, conversion to open surgery, and major adverse cardiovascular or cerebrovascular events at 30 days between different accesses. Major vascular complications were lower in TA [RR 0.43, (95% CI, 0.28-0.67)] and TC [RR 0.51, 95% CI (0.35-0.73)] access compared to TF. The 1-year mortality was higher in TAO [RR of 1.35, (95% CI, 1.01-1.81)] and TA [RR 1.44, (95% CI, 1.14-1.81)] groups. CONCLUSION: Non-thoracic alternative access site utilization for TAVR implantation (TC, TSA and TCV) is associated with outcomes similar to conventional TF access. Thoracic TAVR access (TAO and TA) translates into increased short and long-term mortality.

Transcarotid versus transthoracic access for transcatheter aortic valve replacement: A propensity-matched analysis.

OBJECTIVE: Transcarotid access for transcatheter aortic valve replacement is emerging as an alternative to more traditional nonfemoral access options such as transapical or transaortic; however, comparative data are limited. The purpose of the study was to analyze outcomes after transcatheter aortic valve replacement using transcatheter compared with transthoracic (transapical/transaortic) access. METHODS: The Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry was queried for patients who underwent transcarotid, transapical, or transaortic transcatheter aortic valve replacement with the SAPIEN 3 (Edwards Lifesciences, Irvine, Calif) transcatheter heart valve between June 2015 and July 2019. Thirty-day unadjusted outcomes were evaluated, and propensity score matching and logistic regression were used to compare transcatheter access with transthoracic access. RESULTS: In the propensity-matched analysis, 667 transcarotid transcatheter aortic valve replacement procedures were compared with 1334 transthoracic procedures. Transcarotid transcatheter aortic valve replacement was associated with lower mortality (4.2% vs 7.7%, P = .004), less new-onset atrial fibrillation (2.2% vs 12.1%, P < .0001), fewer readmissions at 30 days (9.8% vs 16.1%, P = .0006), shorter median length of stay (3.0 vs 6.0 days, P < .0001), shorter median intensive care unit stay (25 vs 47.2 hours, P < .0001), and greater 30-day Kansas City Cardiomyopathy Questionnaire score improvement from baseline (25.1 vs 20.8, P = .007). Stroke (4.3% vs 3.7%, P = .44) and major vascular complications (1.4% vs 1.9%, P = .40) were similar. CONCLUSIONS: Transcatheter aortic valve replacement using transcarotid access is associated with lower 30-day mortality, less atrial fibrillation, shorter intensive care unit and overall length of stay, fewer readmissions, greater improvement in Kansas City Cardiomyopathy Questionnaire scores, and no significant difference in stroke or major vascular complications compared with transthoracic access.

Bioprosthetic valve fracture: a practical guide.

Valve-in-valve transcatheter aortic valve replacement (VIV TAVR) is currently indicated for the treatment of failed surgical tissue valves in patients determined to be at high surgical risk for re-operative surgical valve replacement. VIV TAVR, however, often results in suboptimal expansion of the transcatheter heart valve (THV) and can result in patient-prosthesis mismatch (PPM), particularly in small surgical valves. Bioprosthetic valve fracture (BVF) and bioprosthetic valve remodeling (BVR) can facilitate VIV TAVR by optimally expanding the THV and reducing the residual transvalvular gradient by utilizing a high-pressure inflation with a non-compliant balloon to either fracture or stretch the surgical valve ring, respectively. This article, along with the supplemental video, will provide patient selection, procedural planning and technical insights for performing BVF and BVR.

Opioid-Related Adverse Events: Incidence and Impact in Patients Undergoing Cardiac Surgery.

Purpose. Opioid-related adverse drug events (ORADEs) increase patient length of stay (LOS) and health care costs. However, ORADE rates may be underreported. This study attempts to understand the degree to which ORADEs are underreported in Medicare patients undergoing cardiac surgery. Materials and Methods. The Center for Medicare and Medicaid Services administrative claims database was used to identify ORADEs in 110 158 Medicare beneficiaries who underwent cardiac valve (n = 50 525) or coronary bypass (n = 59 633) surgery between April 2016 and March 2017. The International Classification of Disease (ICD)-10 codes specifically linked to ORADEs were used to identify an actual ORADE rate, while additional ICD codes, clinically associated with butas not specific to adverse drug events were analyzed as potential ORADEs. Length of stay (LOS) and hospital daily revenue were analyzed among patients with or without a potential ORADE. Results. Among patients undergoing valve or bypass surgery, the documented ORADE rate was 0.7% (743/110 158). However, potential ORADEs may have occurred in up to 32.4% (35 658/110 158) of patients. In patients with a potential ORADE, mean LOS was longer (11.4 vs 8.2 days; P < .0001) and mean Medicare revenue/day was lower ($4016 vs $4412; P < .0001). The mean net difference in revenue/day between patients with and without an ORADE varied between $231 and $1145, depending on the Diagnosis-Related Group analyzed. Conclusions. ORADEs are likely underreported following cardiac surgery. ORADEs can be associated with increased LOS and decreased hospital revenue. Understanding the incidence and economic impact of ORADEs may expedite changes to postoperative pain management. Adopting multimodal pain management strategies that reduce exposure to opioids may improve outcomes by reducing complications, side effects, and health care costs.

Operator Experience and Outcomes of Transcatheter Mitral Valve Repair in the United States.

BACKGROUND: Transcatheter mitral valve repair (TMVr) for the treatment of mitral regurgitation (MR) is a complex procedure that requires development of a unique skillset. OBJECTIVES: The purpose of this study was to examine the relationship between operator experience and procedural results of TMVr. METHODS: TMVr device procedures from the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy registry were analyzed with operator case number as a continuous and categorical (1 to 25, 26 to 50, and >50) variable. Outcomes of procedural success, procedural time, and in-hospital procedural complications were examined. The learning curve for the procedure was evaluated using generalized linear mixed models adjusting for baseline clinical variables. RESULTS: All TMVr device procedures (n = 14,923) performed by 562 operators at 290 sites between November 2013 and March 2018 were analyzed. Optimal procedural success (≤1+ residual MR without death or cardiac surgery) increased across categories of operator experience (63.9%, 68.4%, and 75.1%; p < 0.001), while procedural time and procedural complications decreased. Acceptable procedural success (≤2+ residual MR without death or cardiac surgery) also increased with operator experience, but the differences were smaller (91.4%, 92.4%, and 93.8%; p < 0.001). These associations remained significant in adjusted, continuous variable analyses. Visual inflection points in the learning curves for procedural time, procedural success, and procedural complications were evident after approximately 50 cases, with continued improvements observed out to 200 cases. CONCLUSIONS: For TMVr device procedures, operator experience was associated with improvements in procedural success, procedure time, and procedural complications. The effect of operator experience was greater when considering the goal of achieving 1+ residual MR.

Association of Smoking Status With Long-Term Mortality and Health Status After Transcatheter Aortic Valve Replacement: Insights From the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry.

Background Smoking is a significant risk factor for aortic stenosis but its impact on clinical and health status outcomes after transcatheter aortic valve replacement (TAVR) has not been described. Methods and Results Patients (n=72 165) undergoing TAVR at 457 US sites in the STS/ACC TVT (Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy) Registry between November 2011 and June 2016 were categorized at the time of TAVR as current/recent smokers versus prior/nonsmokers. A series of multivariable models examined the association between smoking status and outcomes, including 1-year mortality, rehospitalization, mean gradient, and health status (measured by the 12-item Kansas City Cardiomyopathy Questionnaire-Overall Summary Score [KCCQ-OS]) and in-hospital outcomes. A total of 4063 patients (5.6%) were smokers. Smokers presented for TAVR at a younger age (75 [68-81] years versus 83 [77-88] years) but with a greater burden of cardiovascular and lung disease. In adjusted models, smoking was associated with lower in-hospital mortality (relative risk, 0.74; 95% CI, 0.62-0.89 [P=0.001]) but not with in-hospital stroke/transient ischemic attack or myocardial infarction. Smoking status had no association with postdischarge mortality, stroke, myocardial infarction, or heart failure (HF) but was associated with slightly lower 1-year KCCQ-OS scores (2.4-point lower KCCQ-OS; 95% CI, -4.6 to -0.2 [P=0.031]) and higher mean aortic valve gradients (11.1 versus 10.2 mm Hg, P<0.001) in adjusted models. Conclusions The current/recent smoking rate in US patients with TAVR is 5.6% and smokers present at a younger age for TAVR. Smoking was associated with lower in-hospital but similar long-term survival after TAVR, slightly worse long-term health status, and marginally higher mean aortic valve gradients. Further research is needed to understand the effect of smoking cessation on outcomes.

Institutional Experience With Transcatheter Mitral Valve Repair and Clinical Outcomes: Insights From the TVT Registry.

OBJECTIVES: The aim of this study was to examine the relation between institutional experience and procedural results of transcatheter mitral valve repair. BACKGROUND: Transcatheter mitral valve repair for the treatment of mitral regurgitation (MR) is a complex procedure requiring navigation of the left atrium, left ventricle, and mitral valve apparatus using echocardiographic guidance. METHODS: MitraClip procedures from the Society of Thoracic Surgeons/American College of Cardiology TVT (Transcatheter Valve Therapy) Registry were stratified into tertiles on the basis of site-specific case sequence (1 to 18, 19 to 51, and 52 to 482). In-hospital outcomes of procedural success, procedural time, and procedural complications were examined. To evaluate the learning curve for the procedure, generalized linear mixed models were developed using case sequence number as a continuous variable. RESULTS: MitraClip procedures (n = 12,334) performed at 275 sites between November 2013 and September 2017 were analyzed. Optimal procedural success (≤1+ residual MR without mortality or need for cardiac surgery) increased across tertiles of case experience (62.0%, 65.5%, and 72.5%; p < 0.001), whereas procedural time and procedural complications decreased. Acceptable procedural success (≤2+ residual MR without death or need for cardiac surgery) also increased across tertiles of case experience, but the differences were smaller (91.2%, 91.2%; and 92.9%; p = 0.006). In the learning-curve analysis, visual inflection points for procedural time, procedural success, and procedural complications were evident after about 50 cases, with continued improvements observed up to 200 cases. CONCLUSIONS: For transcatheter mitral valve repair with the MitraClip, increasing institutional experience was associated with improvements in procedural success, procedure time, and procedural complications. The impact of institutional experience was larger when considering the goal of achieving optimal MR reduction.

Bioprosthetic valve fracture: Technical insights from a multicenter study.

OBJECTIVE: Valve-in-valve transcatheter aortic valve replacement (VIV TAVR) can result in high residual gradients that are associated with increased mortality. Bioprosthetic valve fracture (BVF) has been shown to improve residual gradients following VIV TAVR; however, factors influencing the results of BVF have not been studied. METHODS: BVF was performed in 75 patients at 21 centers. Hierarchical multiple linear regression was performed to identify variables that were associated with lower final transvalvular gradient. RESULTS: Surgical valves with a median true internal diameter of 18.5 mm (interquartile range, 17.0-20.5 mm) were treated with VIV TAVR in conjunction with BVF using balloon-expandable (n = 43) or self-expanding (n = 32) transcatheter heart valves with a median size of 23 mm (interquartile range, 23-23 mm). There were no aortic root disruptions, coronary occlusions, or new pacemakers; in-hospital or 30-day mortality was 2.6% (2 out of 75). Final mean transvalvular gradient was 9.2 ± 6.3 mm Hg, but was significantly lower when BVF was performed after VIV TAVR compared with BVF first (8.1 ± 4.8 mm Hg vs 16.9 ± 10.1 mm Hg; P < .001). After adjusting for timing of BVF (ie, before or after VIV TAVR), transcatheter heart valve size/type, surgical valve mode of failure, true internal diameter, and baseline gradient and BVF balloon size, performing BVF after VIV TAVR (P < .001) and using a larger BVF balloon (P = .038) were the only independent predictors of lower final mean gradient. CONCLUSIONS: BVF can be performed safely and results in reduced residual transvalvular gradients. Performing BVF after VIV TAVR and using larger balloon appears to achieve the best hemodynamic results.

Transcarotid Versus Transapical and Transaortic Access for Transcatheter Aortic Valve Replacement.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) using transcarotid access may improve outcomes compared with transapical or transaortic access. METHODS: This study retrospectively evaluated 165 patients who were undergoing alternate access TAVR using transcarotid (n = 84), transapical (n = 48), and transaortic (n = 33) access. The 30-day outcomes and 2-year Kaplan-Meier survival were analyzed using a multivariable Cox proportional hazards model. RESULTS: The median Society of Thoracic Surgeons predicted risk of mortality was similar among patients treated by transcarotid, transapical, and transaortic access (9.0% [interquartile range (IQR), 6.6, 12.0] vs 9.1% [IQR, 7.0, 11.7] vs 10.0% [IQR, 8.5, 13.0]; p = 0.14), respectively. Patients treated with transcarotid TAVR had a trend toward lower 30-day mortality (3.6% [3 of 84] vs 6.3% [3 of 48] vs 15.2% [5 of 33]; p = 0.09) and significantly better 2-year survival (88.4% vs 79.2% vs 63.6%; p = 0.004) compared with patients treated by transapical and transaortic access, respectively. In addition, transcarotid access was associated with a shorter median length of stay (3.0 days [IQR, 2.0, 5.0] vs 6.5 days [IQR. 5.0, 9.5] vs 7.0 days [IQR, 5.0, 9.0]; p < 0.001), lower transfusion rate (4.8% [4 of 84] vs 12.0% [12 of 48] vs 24.2% [8 of 33]; p < 0.001), higher likelihood of discharge to home without home health care (89.3% [75 of 84] vs 54.2% [26 of 48] vs 42.4% [14 of 33]; p < 0.001), and similar 30-day stroke rates (2.4% [2 of 84] vs 2.1% [1 of 48] vs 3.0% [1 of 33];p = 0.9). CONCLUSIONS: Transcarotid compared with transapical and transaortic access for TAVR is associated with shorter length of stay, fewer transfusions, more frequent discharge to home, and better 2-year survival.

Is Bioprosthetic Valve Fracture Beneficial for Patients with Larger Surgical Valves Undergoing Valve in Valve TAVR?

PURPOSE OF REVIEW: This review aims to summarize data regarding bioprosthetic valve fracture (BVF), a novel technique that involves fracturing the surgical valve sewing ring to allow for further expansion of the transcatheter heart valve in patients undergoing valve in valve transcatheter aortic valve replacement (VIV TAVR). RECENT FINDINGS: Bench testing and clinical experience have demonstrated that most, but not all, bioprosthetic surgical valves can be fractured. BVF in patients with small- and intermediate-sized surgical valves results in a lower residual valve gradient and larger final valve effective orifice area as compared with standard VIV TAVR. However, whether patients with larger bioprothetic valves benefit from BVF, and whether the hemodynamic benefits of BVF translate into improved clinical outcomes, is unknown. BVF improves the hemodynamic results of VIV TAVR in small surgical valves. However, further research is needed to determine whether BVF is beneficial for patients with larger surgical valves, and whether the hemodynamic benefits of BVF result in improved clinical outcomes.

Intravenous Acetaminophen Improves Outcomes After Transapical Transcatheter Aortic Valve Replacement.

OBJECTIVE: Complications with opioid-based postoperative pain management have led to guideline recommendations for a multimodal analgesia strategy incorporating nonopioid agents. We evaluated the opioid-sparing effect of intravenous acetaminophen in patients undergoing transapical transcatheter aortic valve replacement. METHODS: A multimodal pain management strategy that incorporated intravenous acetaminophen was retrospectively evaluated in 43 patients undergoing transapical transcatheter aortic valve replacement between November 2012 and March 2014. Before intravenous acetaminophen formulary availability, 23 patients received standard postoperative pain management interventions including intravenous narcotics and oral narcotics/acetaminophen. After intravenous acetaminophen availability, 20 patients received intravenous acetaminophen (4 g/d, ≥4 doses) and supplemental intravenous and nonacetaminophen oral narcotics. Daily narcotic dose (standardized to morphine equivalents), drug cost, and hospital length of stay were compared between groups. RESULTS: Baseline characteristics were similar between intravenous acetaminophen (n = 20) and nonintravenous acetaminophen (n = 23) patients including the Society of Thoracic Surgery mortality risk (10.5% vs 9.0%, P = 0.3). The median number of intravenous acetaminophen doses was 6.5 (interquartile range = 4.0-18.5), with a median cost per patient of US $221 (interquartile range = $136-$629). Patients who received intravenous acetaminophen used significantly fewer morphine equivalents on postoperative day 0 compared with patients not receiving intravenous acetaminophen (22.5 vs 45.0 morphine equivalents, P = 0.03) and had a shorter median length of stay (5.0 vs 7.0 days, P = 0.007). After adjusting for the Society of Thoracic Surgery risk, intravenous acetaminophen continued to be associated with a reduction in median postoperative length of stay [-1.9 days (95% confidence interval = -0.9 to -8.2 days), P = 0.049]. CONCLUSIONS: In patients undergoing transapical transcatheter aortic valve replacement, a multimodal pain management strategy incorporating intravenous acetaminophen was associated with reductions in narcotic use on the day of surgery and overall length of stay.

Incidence, predictors and clinical outcomes of residual stenosis after aortic valve-in-valve.

OBJECTIVE: We aimed to analyse the incidence of prosthesis-patient mismatch (PPM) and elevated gradients after aortic valve in valve (ViV), and to evaluate predictors and associations with clinical outcomes of this adverse event. METHODS: A total of 910 aortic ViV patients were investigated. Elevated residual gradients were defined as ≥20 mm Hg. PPM was identified based on the indexed effective orifice area (EOA), measured by echocardiography, and patient body mass index (BMI). Moderate and severe PPM (cases) were defined by European Association of Cardiovascular Imaging (EACVI) criteria and compared with patients without PPM (controls). RESULTS: Moderate or greater PPM was found in 61% of the patients, and severe in 24.6%. Elevated residual gradients were found in 27.9%. Independent risk factors for the occurrence of lower indexed EOA and therefore severe PPM were higher gradients of the failed bioprosthesis at baseline (unstandardised beta -0.023; 95% CI -0.032 to -0.014; P<0.001), a stented (vs a stentless) surgical bioprosthesis (unstandardised beta -0.11; 95% CI -0.161 to -0.071; P<0.001), higher BMI (unstandardised beta -0.01; 95% CI -0.013 to -0.007; P<0.001) and implantation of a SAPIEN/SAPIEN XT/SAPIEN 3 transcatheter device (unstandardised beta -0.064; 95% CI -0.095 to -0.032; P<0.001). Neither severe PPM nor elevated gradients had an association with VARC II-defined outcomes or 1-year survival (90.9% severe vs 91.5% moderate vs 89.3% none, P=0.44). CONCLUSIONS: Severe PPM and elevated gradients after aortic ViV are very common but were not associated with short-term survival and clinical outcomes. The long-term effect of poor post-ViV haemodynamics on clinical outcomes requires further evaluation.

Bioprosthetic Valve Fracture to Facilitate Transcatheter Valve-in-Valve Implantation.

BACKGROUND: Valve-in-valve transcatheter aortic valve replacement is less effective in small surgical bioprostheses. We evaluated the feasibility of bioprosthetic valve fracture with a high-pressure balloon to facilitate valve-in-valve transcatheter aortic valve replacement. METHODS: In vitro bench testing on aortic tissue valves was performed on 19-mm and 21-mm Mitroflow (Sorin, Milan, Italy), Magna and Magna Ease (Edwards Lifesciences, Irvine, CA), Trifecta and Biocor Epic (St. Jude Medical, Minneapolis, MN), and Hancock II and Mosaic (Medtronic, Minneapolis, MN). High-pressure balloons Tru Dilation, Atlas Gold, and Dorado (C.R. Bard, Murray Hill, NJ) were used to determine which valves could be fractured and at what pressure fracture occurred. RESULTS: Mitroflow, Magna, Magna Ease, Mosaic, and Biocor Epic surgical valves were successfully fractured using high-pressures balloon 1 mm larger than the labeled valve size whereas Trifecta and Hancock II surgical valves could not be fractured. Only the internal valve frame was fractured, and the sewing cuff was never disrupted. Manufacturer's rated burst pressures for balloons were exceeded, with fracture pressures ranging from 8 to 24 atmospheres depending on the surgical valve. Testing further demonstrated that fracture facilitated the expansion of previously constrained, underexpanded transcatheter valves (both balloon and self-expanding) to the manufacturer's recommended size. CONCLUSIONS: Bench testing demonstrates that the frame of most, but not all, bioprosthetic surgical aortic valves can be fractured using high-pressure balloons. The safety of bioprosthetic valve fracture to optimize valve-in-valve transcatheter aortic valve replacement in small surgical valves requires further clinical investigation.

Beyond restenosis: Patients' preference for drug eluting or bare metal stents.

OBJECTIVES: To assess patients' perspective about factors associated with stent choice. BACKGROUND: Drug eluting stents (DES) markedly reduce the risk of repeat percutaneous coronary intervention (PCI), but necessitate a longer duration of dual anti-platelet therapy (DAPT) as compared with bare metal stents (BMS). Thus, understanding patients' perspective about factors associated with stent choice is paramount. METHODS: Patients undergoing angiography rated, on a 10-point scale, the importance (1 = not important, 10 = most important) of avoiding repeat revascularization and avoiding the following potential DAPT drawbacks: bleeding/bruising, more pills/day, medication costs and delaying elective surgery. The factor, or group of factors, that was rated highest by each patient was identified. RESULTS: Among 311 patients, repeat revascularization was the single most important consideration to 14.4% of patients, while 20.6% considered avoiding one of the DAPT drawbacks as most important. Most patients (65%) considered avoiding at least one DAPT drawback as important as avoiding repeat revascularization. In no subgroup of patients did more than a quarter of patients prefer avoiding repeat revascularization above all other concerns. Among patients undergoing PCI, more than three quarters received a DES, regardless of their stated preferences (DES use among those most valuing DES benefits, avoiding DAPT drawbacks, or both equally were 78.7%, 86.2%, and 85.6%, respectively, P = 0.56). CONCLUSION: Most patients reported that avoiding DAPT drawbacks was as important as avoiding repeat revascularization. Eliciting patient preferences regarding stent type can enhance shared decision-making and allow physicians to better tailor stent choice to patients' goals and values.

Combined Transcatheter Aortic Valve Replacement and Thoracic Endovascular Aortic Repair Using Transapical Access.

Vascular complications remain an important consideration when selecting access for delivery of large endovascular devices. With the advent of transcatheter aortic valve replacement, transapical access has become an acceptable technique when transfemoral or direct transaortic access is contraindicated. We report the use of the transapical approach during thoracic aortic endovascular repair in 2 patients, one of which included concomitant delivery of a transcatheter aortic valve replacement device. To our knowledge, this is the first reported case of a hybrid single-stage transcatheter aortic valve replacement and thoracic aortic endovascular repair using transapical access.

Myocardial infarction secondary to a coronary ostial thrombus in antiphospholipid syndrome.

A 44-year-old woman presented with an acute inferior ST elevation myocardial infarction, followed by a stroke in the right hemisphere. To search for a cardiac source of embolism, a transesophageal echocardiogram was performed, which showed a mass obstructing the origin of the right coronary artery. The mass was surgically excised and a histologic examination confirmed its thrombotic origin. The diagnosis of antiphospholipid antibody syndrome was confirmed by positive lupus anticoagulant antibodies.
