Comparison of In-Hospital Outcomes between Early and Late Catheter-Directed Thrombolysis in Acute Pulmonary Embolism: A Retrospective Observational Study.

The purpose of this study is to evaluate whether early initiation of catheter-directed thrombolysis (CDT) in patients presenting with acute pulmonary embolism is associated with improved in-hospital outcomes. A retrospective cohort was extracted from the 2016-2019 National Inpatient Sample database, consisting of 21,730 weighted admissions undergoing CDT acute PE. From the time of admission, the sample was divided into early (<48 h) and late interventions (>48 h). Outcomes were measured using regression analysis and propensity score matching. No significant differences in mortality, cardiac arrest, cardiogenic shock, or intracranial hemorrhage (p > 0.05) were found between the early and late CDT groups. Late CDT patients had a higher likelihood of receiving systemic thrombolysis (3.21 [2.18-4.74], p < 0.01), blood transfusion (1.84 [1.41-2.40], p < 0.01), intubation (1.33 [1.05-1.70], p = 0.02), discharge disposition to care facilities (1.32 [1.14-1.53], p < 0.01). and having acute kidney injury (1.42 [1.25-1.61], p < 0.01). Predictors of late intervention were older age, female sex, non-white ethnicity, non-teaching hospital admission, hospitals with higher bed sizes, and weekend admission (p < 0.01). This study represents a comprehensive evaluation of outcomes associated with the time interval for initiating CDT, revealing reduced morbidity with early intervention. Additionally, it identifies predictors associated with delayed CDT initiation. The broader ramifications of these findings, particularly in relation to hospital resource utilization and health disparities, warrant further exploration.

Perioperative outcomes of hypertrophic cardiomyopathy: An insight from the National Readmission Database.

BACKGROUND: Data regarding hypertrophic obstructive cardiomyopathy (HOCM) patients undergoing noncardiac surgery is lacking. We sought to examine the perioperative outcomes of HOCM patients undergoing noncardiac surgery using a national database. METHODS: We used the National readmission database from 2016 to 2019. We identified HOCM, heart undergoing noncardiac surgery using ICD 10 codes. We examined hospital outcomes as well as 90 days readmission outcomes. RESULTS: We identified 16,098 HOCM patients and 21,895,699 non-HOCM patients undergoing noncardiac surgery. The HOCM group had more comorbidities at baseline. After adjustment for major clinical predictors, the HOCM group experienced more in-hospital death, odds ratio (OR) 1.33 (1.216-1.47), P < 0.001, acute myocardial infarction (AMI), OR 1.18 (1.077-1.292), P < 0.001, acute heart failure odds ratio OR 1.3 to (1.220-1.431), P < 0.001, 90 days readmission OR 1.237 (1.069-1.432), P < 0.01, cardiogenic shock OR 2.094 (1.855-2.363), P < 0.001. Cardiac arrhythmia was the most common cause of readmission, out of the arrhythmias atrial fibrillation was the most prevalent. Acute heart failure was the most common complication of readmission. There was no difference in major adverse cardiovascular events (MACE), and AMI between both groups and readmission. CONCLUSION: HOCM patients undergoing noncardiac surgery may be at increased risk of in-hospital and readmission events. Acute heart failure was the most common complication during index admission, while cardiac arrhythmias were the most common complication during readmission. More research is needed to address this patient population further.

Atrial Speckle Tracking Echocardiography for Detecting Atrial Fibrillation in Cryptogenic Stroke: A Meta-Analysis.

Cryptogenic stroke (CS) accounts for approximately 25% of ischemic stroke cases, with atrial fibrillation (AF) accounting for 30% of CS cases. We investigated the utility of left atrial (LA) speckle-tracking echocardiography in identifying patients at high risk of AF after CS and potentially guiding patients who will benefit from long-term rhythm monitoring devices. Cochrane Library, MEDLINE, and EMBASE were searched for relevant studies. We included studies that examined patients with new CS without a history of AF and further examined LA strain parameters (peak and/or reservoir strain). Continuous data were pooled as a mean difference (MD) comparing patients who developed AF vs no AF.  We used the inverse variance method with the DerSimonian-Laird estimator for tau2 and Hartung-Knapp adjustment for random effect analysis. I2 was used to assess heterogeneity. Thirteen observational studies met our criteria and included 3031 patients with new CS. Of those, 420 patients developed AF on follow-up, and 2611 patients did not develop AF. The AF group vs. no AF had significantly reduced LA reservoir strain (LARS) [MD: -8.61; 95% CI: -10.76, -6.47, I2 = 85%, p < 0.01] at presentation. LARS is significantly lower in patients who developed AF after CS. More studies are needed to validate this data.

Characteristics and Outcomes of Early vs Late Initiation of Mechanical Circulatory Support in Non-Acute Myocardial Infarction related Cardiogenic Shock: An Analysis of the National Inpatient Sample Database.

Cardiogenic shock (CS) is significant cause of mortality. The use of mechanical circulatory support (MCS) in patients with non-acute myocardial infarction (Non-AMI) CS is lacking. We inquired data regarding the trends and outcomes early vs late initiation of MCS in non-AMI CS. We investigated National Inpatient Sample database between October 2015-December 2018, identifying hospitalizations with CS, either complicated by AMI or Non-AMI. Patients were divided into 2 cohorts, early initiation of MCS (<48 hours) and late initiation of MCS (>48 hours). The primary analysis included death within first 24 hours. A secondary analysis was adjusted after excluding patients who died in first 24 hours. A total of 85,318 patients with non-AMI-related CS with MCS placement were identified. Among this cohort, 54.6% (n=46,579) underwent early initiation of MCS within 48 hours, and 45.4% (n=38,739) underwent late initiation of MCS after 48 hours. In primary analysis, early MCS initiation was associated with more in-hospital mortality in primary outcome of all-cause hospital mortality (35.72% vs 27.63%, P<0.0001, OR 1.44, 95% CI: 1.40-1.49, P<0.0001), however, adjusted secondary analysis showed a statistically significant decrease in all-cause hospital mortality (23.63% vs 27.63%, P<0.0001, OR 0.80, 95% CI: 0.78-0.83, P<0.0001). In non-AMI-related CS and based on survival to 24 hours after admission, early initiation of MCS had statistically significant decrease in all-cause hospital mortality, with less incidence of vascular and renal complications, and shorter hospital stay. Late initiation of MCS was associated with a higher incidence of advanced therapies, including LVAD and transplant.

Meta-analysis Comparing Percutaneous Coronary Intervention With Coronary Artery Bypass Grafting for Non-ST Elevation Acute Coronary Syndrome in Patients With Multivessel or Left Main Disease.

Outcomes of patients presenting with non-ST-elevation acute coronary syndrome (NSTE-ACS) with multivessel coronary disease (MVD) and/or unprotected left main coronary artery disease (CAD) revascularized with percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) is not well defined. MEDLINE/PubMed and EMBASE/Ovid were queried for studies that investigated PCI vs CABG in this disease subset. The primary outcome was major cardiac adverse events (MACE) at 30 days and long-term follow-up (3-5 years). The final analysis included 9 studies with a total of 9299 patients. No significant difference was observed between PCI and CABG in 30 days MACE (risk ratio [RR] 0.96; 95% confidence interval [CI] 0.38-2.39, all-cause mortality, myocardial infarction, and stroke. A meta-regression analysis revealed patients with a history of PCI had higher risk of MACE with PCI as compared with CABG. At long-term follow-up, PCI compared with CABG was associated with higher risk of MACE (RR 1.52; 95% CI 1.28-1.81), myocardial infarction, and repeat revascularization, while no difference was observed in the risk of stroke and all-cause mortality. In patients with NSTE-ACS and MVD or unprotected left main CAD, no differences were observed in the clinical outcomes between PCI and CABG at 30 days follow-up. With long-term follow-up, PCI was associated with a higher risk of MACE.

Outcomes of Cardiac Arrest and Cardiopulmonary Resuscitation in Patients With Left Ventricular Assist Device; an Insight From a National Inpatient Sample.

BACKGROUND: Outcomes of patients with implanted left ventricular assist device (LVAD) implantation experiencing a cardiac arrest (CA) are not well reported. We aimed at defining the in-hospital outcomes of patients with implanted LVAD experiencing a CA. METHODS: The national inpatient sample (NIS) was queried using ICD9/ICD10 codes for patients older than 18 years with implanted LVAD and CA between 2010-2018. We excluded patients with orthotropic heart transplantation, biventricular assist device (BiVAD) implantation and do not resuscitate (DNR) status. RESULTS: A total of 93,153 hospitalisations between 2010 and 2018 with implanted LVAD were identified. Only 578 of these hospitalisations had experienced CA and of those, 173 (33%) hospitalisations underwent cardiopulmonary resuscitation (CPR). The mean age of hospitalisations that experienced a CA was 60.61±14.85 for non-survivors and 56.23±17.33 for survivors (p=0.14). The in-hospital mortality was 60.8% in hospitalisations with CA and 74.33% in hospitalisations in whom CPR was performed. In an analysis comparing survivors with non-survivors, non-survivors had more diabetes mellitus (DM) (p=0.01), and ischaemic heart disease (IHD) (p=0.04). Age, female sex, peripheral vascular disease and history of coronary artery bypass graft (CABG) were independently associated with increased mortality in our cohort. Also, ventricular tachycardia (VT) and CPR were independently associated with in-hospital mortality. During the study period, there was a significantly decreasing trend in performing CPR in LVAD hospitalisations with CA. CONCLUSION: In conclusion, age, female sex, peripheral vascular disease, history of CABG, VT and CPR were independently associated with in-hospital mortality in LVAD hospitalisations who experienced CA.

Sex Differences in Trends and In-Hospital Outcomes Among Patients With Critical Limb Ischemia: A Nationwide Analysis.

Background Critical limb ischemia (CLI) represents the most severe form of peripheral artery disease and is associated with significant mortality and morbidity. Contemporary data comparing the sex differences in trends, revascularization strategies, and in-hospital outcomes among patients with CLI are scarce. Methods and Results Using the National Inpatient Sample database years 2002 to 2015, we identified hospitalizations for CLI. Temporal trends for hospitalizations for CLI were evaluated. The differences in demographics, revascularization, and in-hospital outcomes between both sexes were compared. Among 2 400 778 CLI hospitalizations, 43.6% were women. Women were older and had a higher prevalence of obesity, hypertension, heart failure, and prior stroke. Women were also less likely to receive any revascularization (34.7% versus 35.4%, P<0.001), but the trends of revascularization have been increasing among both sexes. Revascularization was associated with lower in-hospital mortality among women (adjusted odds ratio [OR], 0.76; 95% CI, 0.71-0.81) and men (adjusted OR, 0.69; 95% CI, 0.65-0.73). On multivariable analysis adjusting for patient- and hospital-related characteristics as well as revascularization, women had a higher incidence of in-hospital mortality, postoperative hemorrhage, need for blood transfusion, postoperative infection, ischemic stroke, and discharge to facilities compared with men. Conclusions In this nationwide contemporary analysis of CLI hospitalizations, women were older and less likely to undergo revascularization. Women had a higher incidence of in-hospital mortality and bleeding complications compared with men. Sex-specific studies and interventions are needed to minimize these gaps among this high-risk population.

Echocardiography, lung ultrasound, and cardiac magnetic resonance findings in COVID-19: A systematic review.

BACKGROUND: The manifestations of COVID-19 as outlined by imaging modalities such as echocardiography, lung ultrasound (LUS), and cardiac magnetic resonance (CMR) imaging are not fully described. METHODS: We conducted a systematic review of the current literature and included studies that described cardiovascular manifestations of COVID-19 using echocardiography, CMR, and pulmonary manifestations using LUS. We queried PubMed, EMBASE, and Web of Science for relevant articles. Original studies and case series were included. RESULTS: This review describes the most common abnormalities encountered on echocardiography, LUS, and CMR in patients infected with COVID-19.

Meta-analysis of Safety and Efficacy of Anticoagulation versus no Anticoagulation in Octogenarians and Nonagenarians with Atrial Fibrillation.

INTRODUCTION: The role of anticoagulation in octogenarians and nonagenarians with atrial fibrillation (AF) is controversial due to the lack of evidence from randomized controlled trials (RCTs), owing to the under representation of these patients in clinical trials. AIM: In the present meta-analysis we aim at comparing the clinical benefits and risk of anticoagulation (AC) with no AC in octogenarians and nonagenarians. METHODS: We systematically searched MEDLINE/PubMed, EMBASE/Ovid, and Web of Science databases from the inception to October, 2020. Studies were eligible for inclusion if they met the following criteria: studies comparing AC with no AC in patients aged 80 or more for AF and reported thromboembolic events (TE) and bleeding outcomes. We used Mantel-Haenszel method with a Paule-Mandel estimator of Tau2 with Hartung Knapp-Sidik-Jonkman adjustment to estimate risk ratio (RR) with a 95% confidence interval (CI). Outlier analysis was used to adjust for statistical heterogeneity. RESULTS: A total of 10 observation studies and 1 RCT were included in the final analysis. There was no difference in the risk of TE with AC in octogenarians and nonagenarians compared with no AC, before [RR: 0.87, 95% CI 0.62-1.23, I2: 71%, GRADE confidence "very low"] and after [RR: 0.83, 95% CI 0.66-1.04, I2: 55.5%] adjusting for statistical heterogeneity among studies. In the unadjusted analysis, no difference in the risk of bleeding events was observed between both groups [RR: 1.05, 95% CI 0.62-1.77, I2: 86%, GRADE confidence "very low"]. After adjusting for heterogeneity, AC was associated with an increased risk of bleeding compared with those not receiving AC [RR: 1.57, 95% CI 1.44-1.71, I2: 0%]. AC in octogenarians was not associated with a net clinical benefit compared with no AC. CONCLUSIONS: This meta-analysis did not demonstrate any difference in the risk TE in octogenarians and nonagenarians with AF on AC vs. no AC, in both the adjusted and unadjusted analyses. Also, the risk of bleeding events in the unadjusted analysis was similar between both groups. The adjusted analysis showed an increased risk of bleeding in the AC group compared with no AC group. More data is needed to establish safety and efficacy of AC in this vulnerable patient population. The results of this analysis should be interpreted with caution due to the observational nature of most studies included, and the only RCT reported lower rates of TE and similar risk of bleeding.

Impact of Arrhythmias on Hospitalizations in Patients With Cardiac Amyloidosis.

Cardiac involvement in amyloidosis is associated with a poor prognosis. Data on the burden of arrhythmias in patients with cardiac amyloidosis (CA) during hospitalization are lacking. We identified the burden of arrhythmias using the National Inpatient Sample (NIS) database from January 2016 to December 2017. We compared patient characteristics, outcomes, and hospitalization costs between CA patients with and without documented arrhythmias. Out of 5,585 hospital admissions for CA, 2,020 (36.1%) had concurrent arrhythmias. Propensity-score matching for age, sex, income, and co-morbidities was performed with 1,405 CA patients with arrhythmias and 1,405 patients without. The primary outcome of all-cause mortality was significantly higher in CA patients with arrhythmia than without(13.9% vs 5.3%, p-value <0.001). Atrial fibrillation (AF) was the most common (72.2%) arrhythmia in CA patients with concurrent arrhythmia. The secondary outcomes of AF-related mortality (11.95% vs 9.16%, p-value = 0.02) and acute and acute on chronic as heart failure (HF) exacerbation (32.38% vs 24.91%, p-value <0.0001) were significantly higher in CA and concurrent arrhythmia compared with CA patients without. The total length of hospital stay (6[3 to 12] vs 5[3 to 10], p-value <0.001) and cost of hospitalization were ($ 15,086[7,813 to 30,373] vs $ 12,219[6,865 to 23,997], p-value = 0.001) were significantly greater among CA with arrhythmia compared with those without. These data suggest that the presence of arrhythmias in CA patients during hospital admission is associated with a poorer prognosis and may reflect patients with a higher risk of HF exacerbation and mortality.

Impact of continuous positive airway pressure ventilation on cardiovascular outcomes among patients with obstructive sleep apnea: A meta-analysis of randomized trials.

Background: The impact of continuous positive airway pressure (CPAP) on cardiovascular outcomes among patients with obstructive sleep apnea (OSA) is controversial. Objective: To evaluate the impact of CPAP on reducing cardiovascular outcomes in patients with OSA. Methods: We performed a computerized search of MEDLINE, EMBASE and COCHRANE databases through April 2021 for randomized trials evaluating the impact of CPAP versus control on cardiovascular outcomes in patients with OSA. Summary estimates were reported using both fixed and random effects model. The main study outcome was major adverse cardiac events (MACE). Results: The final analysis included 8 randomized trials with total of 5684 patients. The weighted mean follow-up was 42.6 months. There was no difference between the CPAP and control groups in the risk of MACE (14.4% versus 14.8%, risk ratio [RR]: 0.97; 95% confidence interval [CI]: 0.85 to 1.10; p = 0.60; I2 = 21%). Subgroup analysis suggested that CPAP was associated with lower MACE (by 36%) in CPAP-adherent patients (≥4 h/night) (Pinteraction = 0.08). There was no difference between the CPAP and control groups in the risk of all-cause mortality, cardiovascular mortality, acute stroke, acute myocardium infarction or hospitalizations for angina. Conclusions and relevance: CPAP use might not be associated with lower cardiovascular events among patients with OSA. However, patients adherent to CPAP (≥4 h/night) might derive a benefit on cardiovascular outcomes. Future studies are warranted to evaluate the impact of CPAP in reducing cardiovascular events among patients with severe OSA and with optimal adherence rates to CPAP therapy.

A Systematic Review of the Cardiovascular Manifestations and Outcomes in the Setting of Coronavirus-19 Disease.

The impact of coronavirus disease, 2019 (COVID-19), has been profound. Though COVID-19 primarily affects the respiratory system, it has also been associated with a wide range of cardiovascular (CV) manifestations portending extremely poor prognosis. The principal hypothesis for CV involvement is through direct myocardial infection and systemic inflammation. We conducted a systematic review of the current literature to provide a foundation for understanding the CV manifestations and outcomes of COVID-19. PubMed and EMBASE databases were electronically searched from the inception of the databases through 27 April 2020. A second literature review was conducted to include major trials and guidelines that were published after the initial search but before submission. The inclusion criteria for studies to be eligible were case reports, case series, and observation studies reporting CV outcomes among patients with COVID-19 infection. This review of the current COVID-19 disease and CV outcomes literature revealed a myriad of CV manifestations with potential avenues for treatment and prevention. Future studies are required to understand on a more mechanistic level the effect of COVID-19 on the myocardium and thus provide avenues to improve mortality and morbidity.

Assessment of right ventricular function following left ventricular assist device (LVAD) implantation-The role of speckle-tracking echocardiography: A meta-analysis.

BACKGROUND: Right ventricular failure (RVF) following left ventricular assist device (LVAD) implantation is associated with worse outcomes. Prediction of RVF is difficult with routine transthoracic echocardiography (TTE), while speckle-tracking echocardiography (STE) showed promising results. We performed systematic review and meta-analysis of published literature. METHODS: We queried multiple databases to compile articles reporting preoperative or intraoperative right ventricle global longitudinal strain (RVGLS) or right ventricle free wall strain (RVFWS) in LVAD recipients. The standard mean difference (SMD) in RVGLS and RVFWS in patients with and without RVF postoperatively was pooled using random-effects model. RESULTS: Seventeen studies were included. Patients with RVF had significantly lower RVGLS and RVFWS as compared to non-RVF patients; SMD: 2.79 (95% CI: -4.07 to -1.50; P: <.001) and -3.05 (95% CI: -4.11 to -1.99; P: <.001), respectively. The pooled odds ratio (OR) for RVF per percentage increase of RVGLS and RVFWS were 1.10 (95 CI: 0.98-1.25) and 1.63 (95% CI 1.07-2.47), respectively. In a subgroup analysis, TTE-derived GLS and FWS were significantly lower in RVF patients as compared to non-RVF patients; SMD of -3.97 (95% CI: -5.40 to -2.54; P: <.001) and -3.05 (95% CI: -4.11 to -1.99; P: <.001), respectively. There was no significant difference between RVF and non-RVF groups in TEE-derived RVGLS and RVFWS. CONCLUSION: RVGLS and RVFWS were lower in patients who developed RVF as compared to non-RVF patients. In a subgroup analysis, TTE-derived RVGLS and RVFWS were reduced in RVF patients as compared to non-RVF patients. This difference was not reported with TEE.

Speckle tracking echocardiography can predict subclinical myocardial involvement in patients with sarcoidosis: A meta-analysis.

BACKGROUND: This meta-analysis aims to evaluate the utility of speckle tracking echocardiography (STE) as a tool to evaluate for cardiac sarcoidosis (CS) early in its course. Electrocardiography and echocardiography have limited sensitivity in this role, while advanced imaging modalities such as cardiac magnetic resonance (CMR) and 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) are limited by cost and availability. METHODS: We compiled English language articles that reported left ventricular global longitudinal strain (LVGLS) or global circumferential strain (GCS) in patients with confirmed extra-cardiac sarcoidosis versus healthy controls. Studies that exclusively included patients with probable or definite CS were excluded. Continuous data were pooled as a standard mean difference (SMD), comparing sarcoidosis group with healthy controls. A random-effect model was adopted in all analyses. Heterogeneity was assessed using Q and I2 statistics. RESULTS: Nine studies were included in our final analysis with an aggregate of 967 patients. LVGLS was significantly lower in the extra-cardiac sarcoidosis group as compared with controls, SMD -3.98, 95% confidence interval (CI): -5.32, -2.64, P < .001, also was significantly lower in patients who suffered major cardiac events (MCE), -3.89, 95% CI -6.14, -1.64, P < .001. GCS was significantly lower in the extra-cardiac sarcoidosis group as compared with controls, SMD: -3.33, 95% CI -4.71, -1.95, P < .001. CONCLUSION: LVGLS and GCS were significantly lower in extra-cardiac sarcoidosis patients despite not exhibiting any cardiac symptoms. LVGLS correlates with MCEs in CS. Further studies are required to investigate the role of STE in the early screening of CS.

Periodontal Inflammation and the Risk of Cardiovascular Disease.

PURPOSE OF REVIEW: The role of oral bacteremia and periodontal inflammation driving atherosclerosis is still under investigation. This review article highlights the role of periodontal inflammation and oral microorganisms in the development and progression of atherosclerosis and cardiovascular diseases. RECENT FINDINGS: Association between periodontal and cardiovascular diseases has been well characterized, but causal correlation is yet to be established. For instance, untreated gingivitis can progress to periodontitis. Periodontal disease has been associated with several systemic diseases one of which is atherosclerosis. One possible association that was documented in literature is that poor oral hygiene leads to bacteremia, which in turn can cause bacterial growth over atherosclerotic coronary artery plaques and possibly worsen coronary artery disease. It is crucial that clinicians understand the association between periodontal and cardiovascular disease. A comprehensive treatment for periodontitis and re-establishment of a healthy periodontium can help in reduction of overall inflammation in the body. This may play an important role in prevention of cardiovascular disease, though future research is needed to establish this.

Temporal Trends and Outcomes of Transcatheter Versus Surgical Aortic Valve Replacement for Bicuspid Aortic Valve Stenosis.

OBJECTIVES: The purpose of this study was to assess the temporal trends of transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic stenosis (AS), and to compare the outcomes between TAVR and surgical aortic valve replacement (SAVR) in this population. BACKGROUND: Randomized trials comparing TAVR to SAVR in AS with bicuspid valve are lacking. METHODS: The study queried the National Inpatient Sample database (years 2012 to 2016) to identify hospitalizations for bicuspid AS who underwent isolated aortic valve replacement. A propensity-matched analysis was used to compare outcomes of hospitalizations for TAVR versus SAVR for bicuspid AS and TAVR for bicuspid AS versus tricuspid AS. RESULTS: The analysis included 31,895 hospitalizations with bicuspid AS, of whom 1,055 (3.3%) underwent TAVR. TAVR was increasingly utilized during the study period for bicuspid AS (ptrend = 0.002). After matching, TAVR and SAVR had similar in-hospital mortality (3.1% vs. 3.1%; odds ratio: 1.00; 95% confidence interval: 0.60 to 1.67). There was no difference between TAVR and SAVR in the rates of cardiac arrest, cardiogenic shock, acute kidney injury, hemopericardium, cardiac tamponade, or acute stroke. TAVR was associated with lower rates of acute myocardial infarction, post-operative bleeding, vascular complications, and discharge to nursing facility as well as a shorter length of hospital stay. On the contrary, TAVR was associated with a higher incidence of complete heart block and permanent pacemaker insertion. TAVR for bicuspid AS was associated with similar in-hospital mortality compared with tricuspid AS. CONCLUSIONS: This nationwide analysis showed similar in-hospital mortality for TAVR and SAVR in patients with bicuspid AS. TAVR for bicuspid AS was also associated with similar in-hospital mortality compared with tricuspid AS. Further studies are needed to evaluate long-term outcomes of TAVR for bicuspid AS.
