Aims There are no comprehensive machine learning (ML) tools used by oncologists to assist with risk identification and referrals to cardio-oncology. This study applies ML algorithms to identify oncology patients at risk for cardiovascular disease for referrals to cardio-oncology and to generate risk scores to support quality of care. Methods and results De-identified patient data were obtained from Vanderbilt University Medical Center. Patients with breast, kidney, and B-cell lymphoma cancers were targeted. Additionally, the study included patients who received immunotherapy drugs for treatment of melanoma, lung cancer, or kidney cancer. Random forest (RF) and artificial neural network (ANN) ML models were applied to analyse each cohort: A total of 20 023 records were analysed (breast cancer, 6299; B-cell lymphoma, 9227; kidney cancer, 2047; and immunotherapy for three covered cancers, 2450). Data were divided randomly into training (80%) and test (20%) data sets. Random forest and ANN performed over 90% for accuracy and area under the curve (AUC). All ANN models performed better than RF models and produced accurate referrals. Conclusion Predictive models are ready for translation into oncology practice to identify and care for patients who are at risk of cardiovascular disease. The models are being integrated with electronic health record application as a report of patients who should be referred to cardio-oncology for monitoring and/or tailored treatments. Models operationally support cardio-oncology practice. Limited validation identified 86% of the lymphoma and 58% of the kidney cancer patients with major risk for cardiotoxicity who were not referred to cardio-oncology.

Bicuspid aortic valve (BAV) is the most common valvular congenital heart disease, with a prevalence of 0.5 to 2% in the general population. Patients with BAV are at risk for developing cardiovascular complications, some of which are life-threatening. BAV has a wide spectrum of clinical presentations, ranging from silent malformation to severe and even fatal cardiac events. Despite the significant burden on both the patients and the health systems, data are limited regarding pathophysiology, risk factors, and genetics. Family studies indicate that BAV is highly heritable, with autosomal dominant inheritance, incomplete penetrance, variable expressivity, and male predominance. Owing to its complex genetic model, including high genetic heterogenicity, only a few genes were identified in association with BAV, while the majority of BAV genetics remains obscure. Here, we review the different forms of BAV and the current data regarding its genetics. Given the clear heritably of BAV with the potential high impact on clinical outcome, the clinical value and cost effectiveness of cascade screening are discussed.

International audience; Background - Infective endocarditis (IE) is a common and serious complication in patients receiving chronic hemodialysis (HD). Objectives - This study sought to investigate whether there are significant differences in complications, cardiac surgery, relapses, and mortality between IE cases in HD and non-HD patients. Methods - Prospective cohort study (International Collaboration on Endocarditis databases, encompassing 7,715 IE episodes from 2000 to 2006 and from 2008 to 2012). Descriptive analysis of baseline characteristics, epidemiological and etiological features, complications and outcomes, and their comparison between HD and non-HD patients was performed. Risk factors for major embolic events, cardiac surgery, relapses, and in-hospital and 6-month mortality were investigated in HD-patients using multivariable logistic regression. Results - A total of 6,691 patients were included and 553 (8.3%) received HD. North America had a higher HD-IE proportion than the other regions. The predominant microorganism was Staphylococcus aureus (47.8%), followed by enterococci (15.4%). Both in-hospital and 6-month mortality were significantly higher in HD versus non-HD-IE patients (30.4% vs. 17% and 39.8% vs. 20.7%, respectively; p

Mitral valve prolapse (MVP) is the most common primary valvular abnormality, associated with various degrees of incompetent function and sequelae, including heart failure and sudden cardiac death. Recent improvements in echocardiographic techniques and new insights into mitral valve anatomy and physiology have rendered the diagnosis of this condition more accurate and reliable. Here we review the genetic etiology, clinical significance, diagnosis, and treatment options for MVP patients.

This study sought to identify risk factors for permanent pacemaker implantation (PPMI) after Transcatheter aortic valve implantation (TAVI) and explain their trends over the last decade. TAVI is performed nowadays for severe aortic stenosis in more patients with lower surgical risk. While most TAVI complications have been reduced, PPMI remains common. In this observational, retrospective cohort analysis, 338 TAVI patients treated between 2008 and 2017 were reviewed. Risk factors were compared between the early (2008–2013) and late years (2014–2017), and a multivariable logistic regression model was used. A decreasing trend in PPMI over time was observed (p for trend = 0.008), as was a lower rate of PPMI in the late period (19.3% vs. 31.7%, p = 0.009). Three variables were identified as independent risk factors for PPMI that also decreased significantly in the late period: valve implantation depth ≥ 8 mm (OR = 4.3, 95% CI 2.3–8.2, p

Cancer patients with heart failure (HF) and severe mitral regurgitation (MR) are often considered to be at risk for surgical mitral valve repair/replacement. Severe MR inducing symptomatic HF may prevent delivery of potentially cardiotoxic chemotherapy and complicate fluid management with other cancer treatments.To evaluate the outcome of percutaneous mitral valve repair (PMVR) in oncology patients with HF and significant MR.Our study comprised 145 patients who underwent PMVR, MitraClip, at Hadassah Medical Center between August 2015 and September 2019, including 28 patients who had active or history of cancer. Data from 28 cancer patients were compared to 117 no-cancer patients from the cohort.There was no significant difference in the mean age of cancer patients and no-cancer patients (76 vs. 80 years, P = 0.16); 67% of the patients had secondary (functional) MR. Among cancer patients, 21 had solid tumor and 7 had hematologic malignancies. Nine patients (32%) had active malignancy at the time of PMVR. The mean short-term risk score of the patients was similar in the two groups, as were both 30-day and 1-year mortality rates (7% vs. 4%, P = 0.52) and (29% vs. 16%, P = 0.13), respectively.PMVR in cancer patients is associated with similar 30-day and 1-year survival rate compared with patients without cancer. PMVR should be considered for cancer patients presenting with HF and severe MR and despite their malignancy. This approach may allow cancer patients to safely receive planned oncological treatment.

International audience; Bicuspid aortic valve (BAV) is a common congenital heart disease, with a 10-fold higher prevalence in first-degree relatives. BAV has different phenotypes based on the morphology of cusp fusion. These phenotypes are associated with different clinical courses and prognoses. Currently, the determinants of the valve phenotype are unknown. In this study we evaluated the role of genetics using familial cohorts. Patients with BAV and their first-degree relatives were evaluated by echocardiography. The concordance in BAV phenotype between pairs of family members was calculated and compared with the concordance expected by chance. We then performed a systematic literature review to identify additional reports and calculated the overall concordance rate. During the study period, 70 cases from 31 families and 327 sporadic cases were identified. BAV was diagnosed in 14% of the screened relatives. The proportions of the morphologies identified was: 12.3% for type 0, 66.2% for type 1-LR, 15.4% for type 1-RN, 4.6% for type 1-NL, and 1.5% for type 2. For the assessment of morphologic concordance, we included 120 pairs of first-degree relatives with BAV from our original cohort and the literature review. Concordance was found only in 62% of the pairs which was not significantly higher than expected by chance. In conclusion, our finding demonstrates intrafamilial variability in BAV morphology, suggesting that morphology is determined by factors other than Mendelian genetics. As prognosis differs by morphology, our findings may suggest that clinical outcomes may vary even between first-degree relatives.

Although practiced to this day, teaching the 'head-to-toe' physical examination (PE) does not appear to fully achieve its objective, and since the 1970s, there have been proposals to replace the traditional teaching of the head-to-toe examination by a selective PE aimed at testing diagnostic hypotheses; by a core PE to be supplemented by additional maneuvers as clinically indicated; and by limiting the number of PE maneuvers to be taught. The need to update the teaching of the PE is further indicated by the availability of hand-held pulse oximeters, spirometry and especially point of care ultrasound devices (PoCUS). This paper is a call to update the introduction of medical students into the PE by (a) teaching the PE by clinical contexts, rather than by organ systems, (b) restricting the number of PE maneuvers by discerning between a core of 'essential' PE signs of urgent conditions, 'important' signs that should supplement the core as clinically indicated, and 'optional' PE signs that are no longer useful, and (c) combining previously proposed alternatives of the traditional head-to-toe PE with application of hand-held ultrasound devices. We provide examples of essential, important and optional signs of the cardiovascular system.

Transcription factor E3 (TFE3), which is a key regulator of cellular adaptation, is expressed in most tissues, including the heart, and is reportedly overexpressed during cardiac hypertrophy. In this study, TFE3's role in cardiac hypertrophy was investigated. To understand TFE3's physiological importance in cardiac hypertrophy, pressure-overload cardiac hypertrophy was induced through transverse aortic constriction (TAC) in both wild-type (WT) and TFE3 knockout mice (TFE3-/-). Eleven weeks after TAC induction, cardiac hypertrophy was observed in both WT and TFE3-/- mice. However, significant reductions in ejection fraction and fractional shortening were observed in WT mice compared to TFE3-/- mice. To understand the mechanism, we found that myosin heavy chain (Myh7), which increases during hemodynamic overload, was lower in TFE3-/- TAC mice than in WT TAC mice, whereas extracellular signal-regulated protein kinases (ERK) phosphorylation, which confers cardioprotection, was lower in the left ventricles of WT mice than in TFE3-/- mice. We also found high expressions of TFE3, histone, and MYH7 and low expression of pERK in the normal human heart compared to the hypertensive heart. In the H9c2 cell line, we found that ERK inhibition caused TFE3 nuclear localization. In addition, we found that MYH7 was associated with TFE3, and during TFE3 knockdown, MYH7 and histone were downregulated. Therefore, we showed that TFE3 expression was increased in the mouse model of cardiac hypertrophy and tissues from human hypertensive hearts, whereas pERK was decreased reversibly, which suggested that TFE3 is involved in cardiac hypertrophy through TFE3-histone-MYH7-pERK signaling.

OBJECTIVES Pleural effusions (PEffs) are known to occur in type B acute aortic dissection (TBAAD). We investigated the relationship between pleural effusion and the development of early or late complications following TBAAD. METHODS The incidence of PEff (defined as at least an obliteration of the costophrenic angle in a frontal projection) diagnosed on their initial chest X-ray in patients with TBAAD enrolled in the International Registry of Acute Aortic Dissection was examined. We analysed in-hospital outcomes and long-term survival separately for patients with and without PEffs (PEff+ versus PEff−, respectively). RESULTS Included were 1252 patients with TBAAD, of whom 224 (17.9%) had PEff. Compared with patients without PEff in the initial chest X-ray, these were significantly older [mean age 67 (SD: 14.7) vs 63.4 (SD: 14.2) years, P = 0.001] and more often female (42.4% vs 34.2%, P = 0.021) and had more comorbidities (known aortic aneurysm, chronic obstructive pulmonary disease, chronic renal failure, diabetes, congestive heart failure or mitral valve disease). PEff was associated with higher in-hospital mortality (16.1% vs 9.1%, P = 0.002) and increased rates of neurological complications (16.6% vs 11.1%, P = 0.029), acute renal failure (27.2% vs 19.7%, P = 0.017) and hypotension (17.4% vs 9.6%, P = 0.001). In addition, patients with PEff underwent aortic repair more frequently (44.6% vs 32.5%, P CONCLUSIONS Patients with TBAAD and evidence of PEff showed a higher in-hospital mortality, are more likely to develop additional in-hospital complications and have a decreased likelihood of survival during follow-up. However, according to propensity-matched analysis, PEff remained not as an independent predictor of worse outcome but might serve as an early surrogate marker to identify higher-risk patients.

Introduction Bicuspid aortic valve (BAV) is the commonest congenital heart valve defect, found in 1% to 2% of the general population and associated with life-threatening complications. Given the high heritability index of BAV, many experts recommend echocardiography for first-degree relatives (FDRs) of an index patient. However, the cost-effectiveness of such cascade screening for BAV has not been fully evaluated. Materials and methods Using a decision-analytic model, we performed a cost-effectiveness analysis of echocardiographic screening of FDRs of BAV index cases. Data on BAV probabilities and BAV complications among FDRs were derived from our institution's BAV familial cohort and from the relevant literature on population-based BAV cohorts with long-term follow-up. Health gain was measured as quality-adjusted life years (QALYs). Cost inputs were based on list prices and literature data. One-way and probabilistic sensitivity analyses were performed to account for uncertainty in the model's variables. Results and disscusion Screening of FDRs was found to be the dominant strategy, being more effective and less costly than no screening, with savings of €208 and gains of 1.6 QALYs. Results were sensitive to the full range of reported BAV rates among FDRs across the literature, with the benefit gradually decreasing from the screening age of 55 years, with trend shifting at the age of 69. Conclusions This economic evaluation model revealed that echocardiographic screening of FDRs of BAV index case is not only clinically important but also highly cost effective and cost-saving. Health gains could be achieved from initiating screening program, along with costs saving. Sensitivity analysis supported the model's robustness, suggesting its generalization.

Purpose Primary sarcoma of the heart is a rare but devastating tumor. Median survival with conventional treatment is 8-12 months. When resection is not feasible, patients often succumb to heart failure secondary to obstruction of blood flow, valve dysfunction, chamber compression or conduction abnormalities. Palliative treatment options include systemic chemotherapy and external beam irradiation. We herein describe a novel technique using endovascular brachytherapy, aiming at reducing tumor mass, alleviating right ventricular pressure overload and at the same time keeping the option of R0 resection viable. Material and methods A 35-year-old man was diagnosed with a non-resectable high-grade intimal sarcoma of the right ventricle (RV), main pulmonary artery (PA) and right PA. After three cycles of doxorubicin and ifosfamide, the patient's symptoms of right heart failure worsened. Imaging documented tumor progression and supra-systemic pulmonary artery pressure. Through a trans-femoral venous access, a brachytherapy sleeve was placed in the RV and main and right PA. A dose of 20 Gy was delivered over a period of ten minutes. Results The patient had an uneventful course and was discharged home 24 hours after the procedure. Ten months after brachytherapy, repeat imaging demonstrated a significant reduction in tumor volume and an increase in pulmonary artery cross-sectional area with a marked reduction of pulmonary artery pressure, leading to a complete resolution of heart failure symptoms. Conclusions Endovascular brachytherapy is a novel, safe and effective therapeutic modality for non-resectable primary cardiac sarcomas either for palliation of obstruction, or tumor mass reduction to allow complete resection.

Contains fulltext : 231547.pdf (Publisher’s version ) (Open Access) With the improvement in survival rate, cardiotoxicity has emerged as a significant adverse effect of cancer therapy. Early diagnosis of subclinical cardiac injury may allow the initiation of cardioprotective therapy and preventing the interruption of optimal cancer therapy and the development of irreversible cardiac dysfunction. In this article, we review the role of two-dimensional speckle tracking echocardiography (2D-STE), beyond the common left ventricle global longitudinal strain in the diagnosis of early subclinical cardiac injury in patients treated with cancer therapies.

Carcinoid heart disease (CHD) is a paraneoplastic cardiac manifestation occurring in patients with carcinoid syndrome (CS) and advanced neuroendocrine malignancy. In about 20-40% of patients with CS, chronic exposure to tumor-released circulating vasoactive peptides typically results in right-sided valvular fibrosis leading to valve dysfunction and right heart failure. CHD remains a significant cause of morbidity and mortality. The management of patients with CHD is complex, as both the systemic malignant disease and the heart involvement have to be addressed. Early diagnosis and timely surgical intervention in selected patients are of utmost importance and offer a survival benefit. In patients with advanced carcinoid heart disease, valve replacement surgery is the most effective option to alleviate cardiac symptoms and contribute to survival outcomes. A collaboration of a multidisciplinary team in centers with experience is required to provide optimal patient management. Here, we review the current literature regarding CHD presentation, pathophysiology, diagnostic tools, and available treatment strategies.

Importance Women with aortopathy conditions are at risk for pregnancy-related aortic dissection, and these conditions may not be recognized until after the aortic dissection occurs. Objective To examine the clinical characteristics, imaging features, and outcomes in women with pregnancy-related acute aortic dissection. Design, Setting, and Participants A cohort study, comprising data from the International Registry of Acute Aortic Dissection (IRAD) (February 1, 1998, to February 28, 2018). The multicenter referral center study included 29 women with aortic dissection during pregnancy or less than 12 weeks post partum in IRAD from 1998 to 2018. Main Outcomes and Measures Clinical features of pregnancy-related aortic dissection to be studied included underlying aortopathy, aortic size, type of aortic dissection, timing of dissection, hypertension, and previous aortic surgery. Results A total of 29 women (mean [SD] age, 32 [6] years) had pregnancy-related aortic dissection, representing 0.3% of all aortic dissections and 1% of aortic dissection in women in the IRAD. Among women younger than 35 years, aortic dissection was related to pregnancy in 20 of 105 women (19%). Thirteen women (45%) had type A aortic dissection, and 16 women (55%) had type B. Aortic dissection onset was known in 27 women (93%): 15 during pregnancy, 4 in the first trimester, and 11 in the third trimester; 12 were post partum, occurring a mean (SD) of 12.5 (14) days post partum. At type A aortic dissection diagnosis, the mean (SD) aortic diameters were sinus of Valsalva, 54.5 (5) mm and ascending aorta, 54.7 (6) mm. At type B aortic dissection diagnosis, the mean (SD) descending aortic diameter was 32.5 (5) mm. Twenty women (69%) had an aortopathy condition or a positive family history: 13 women (65%) with Marfan syndrome, 2 women (10%) with Loeys-Dietz syndrome, 2 women (10%) with bicuspid aortic valves, 2 women (10%) with a family history of aortic disease, and 1 woman (5%) with familial thoracic aortic aneurysm. Aortopathy was not recognized until after aortic dissection in 47% of the women. Twenty-eight women (97%) survived aortic dissection hospitalization. Conclusions and Relevance Aortic dissection complicating pregnancy is rare. Most pregnancy-related aortic dissection is due to an aortopathy often not diagnosed until after aortic dissection. In this study, type A aortic dissections were associated with a dilated aorta, and type B aortic dissections often were not. Recognition of underlying conditions and risks for aortic dissection may improve management of pregnancy in women with aortopathy.

Rupture of Abdominal aortic aneurysm (AAA) is among the 15 leading causes of death after age 65. Using high frequency ultrasound, we showed that photobiomodulation (PBM) prevents formation and progression of AAA in the angiotensin-II (Ang-II)-infused, apolipoprotein-e-deficient mouse model. In the current study we report that while challenge of porcine aortic Smooth Muscle Cells (SMCs) with Ang-II (1 μM) resulted in a marked decay in mitochondrial membrane potential (MitMP) vs non-challenged cells, treatment with PBM (continuous diode laser, 780 nm, 6.7 mW/cm2 , 5 minutes, 2 J/cm2 ) or pre-incubation with estrogen (50 nM, 1 hour) significantly attenuated this deterioration in MitMP. We also report that PBM and estrogen markedly affected porcine aortic SMC contraction and modified mitochondrial dispersion reflecting important influence on SMC function. These studies provide strong evidence of the important underlying role of mitochondria in the preventive effect of PBM on formation and progression of AAA and its reduced incidence and delayed onset in women.

Background People over the age of 85 are a rapidly growing age group with a high incidence of congestive heart failure (CHF), in particular heart failure with preserved ejection fraction (HFpEF). The diagnosis of CHF is challenging and longitudinal data assessing cardiac structure and function are necessary to distinguish physiologic from pathologic cardiac aging. The objective of the study was to determine longitudinal changes in cardiac struture and function from ages 85 to 94 years using home echocardiography. Methods Subjects were recruited from the Jerusalem Longitudinal Cohort Study. Sixty three members of the initial cohort (32F, 31M) who underwent home echocardiography at age 85 were the subjects of the current study and underwent repeat home 2-D and Doppler echocardiographic assessment at age 94. Results There were no significant longitudinal changes in left ventricular mass index (LVMI), however LV end-diastolic volume significantly decreased from 113.4 ± 30 to 103.6 ± 35.5 mL (P < 0.02). Ejection fraction (EF) remained stable, however longitudinal systolic function significantly decreased with age from 7.9 ± 1.8 to 6.6 ± 1.4 cm/s2 (P < 0.0001). Diastolic function as assessed by increased E: e' (11.2 ± 3.4 to 16 ± 7.5, P < 0.0001) and increased left atrial volume index (34.1 ± 11.3 to 42.4 ± 13.7 mL/m2, P < 0.0001) was reduced with aging. Conclusions This study demonstrated preserved EF with decreased longitudinal systolic function and diastolic function without significant change in LV mass. Changes in LV function in the very elderly may be independent of changes in LV geometry.

Detection of cardiomyocyte death is crucial for the diagnosis and treatment of heart disease. Here we use comparative methylome analysis to identify genomic loci that are unmethylated specifically in cardiomyocytes, and develop these as biomarkers to quantify cardiomyocyte DNA in circulating cell-free DNA (cfDNA) derived from dying cells. Plasma of healthy individuals contains essentially no cardiomyocyte cfDNA, consistent with minimal cardiac turnover. Patients with acute ST-elevation myocardial infarction show a robust cardiac cfDNA signal that correlates with levels of troponin and creatine phosphokinase (CPK), including the expected elevation-decay dynamics following coronary angioplasty. Patients with sepsis have high cardiac cfDNA concentrations that strongly predict mortality, suggesting a major role of cardiomyocyte death in mortality from sepsis. A cfDNA biomarker for cardiomyocyte death may find utility in diagnosis and monitoring of cardiac pathologies and in the study of normal human cardiac physiology and development., The detection of cardiomyocyte death is a critical aspect in the diagnosis and monitoring of heart diseases. Here the authors show that cardiomyocyte-specific methylation patterns of circulating cell-free DNA may serve as a biomarker of cardiac cell death in infarcted and septic patients.

Between January 1996 and May 2017, the International Registry on Acute Aortic Dissections has collected information on a total of 6,424 consecutive patients with acute aortic dissection, including 258 individuals with a diagnosis of Marfan syndrome. Patients with Marfan syndrome presented at a significantly younger age compared to patients without Marfan syndrome (38.2±13.2 vs. 63.0±14.0 years; P

Pacing Dependency Following TAVIBackground Conduction disorders requiring permanent pacemaker (PPM) implantation are a known complication of transcatheter aortic valve implantation (TAVI). Indications for permanent pacing in this setting are still controversial. The study aim was to characterize the natural history of conduction disorders related to TAVI, and to identify predictors for long-term pacing dependency. Methods Consecutive patients who underwent TAVI were included in this prospective observational study. The conduction system was investigated by reviewing 12-lead ECGs during hospitalization and up to 1-year follow-up and by analyzing pacemaker interrogation data. Multivariate analysis was performed in order to identify independent predictors for pacemaker dependency. Results Of 110 patients included in the analysis, 38 (34.5%) underwent PPM implantation. Of those, 26 (68.4%) had a long-term pacing dependency (required PPM), while 12 (31.6%) did not (not-required PPM). Logistic regression revealed that baseline RBBB (P = 0.01, OR = 18.0), baseline PR interval (P = 0.019, OR = 1.14), post-TAVI PR interval and the change in PR interval from baseline (P < 0.001 for both, OR = 1.17 for each 10 milliseconds increment) were independent predictors for long-term pacing dependency. A PR interval increment of greater than 28 milliseconds had the best accuracy in predicting pacemaker dependency. Conclusions Increased pre- and postprocedural PR intervals and pre-existing RBBB are reliable predictors for long-term PPM dependency, while left bundle branch block or QRS width are misleading factors. Our study suggests that the decision for implanting PPM after TAVI should be based mostly on the prolongation of the PR interval.

Type A acute aortic dissection (TAAAD) is conventionally treated with surgery; however, some patients are poor surgical candidates and medical management (MM) is occasionally undertaken. Pre-operative factors influencing survival with MM of TAAAD are unknown. This study utilizes the International

There is limited organized “real life” data regarding the long-term structural and functional durability of transcatheter aortic valve implants, a topic of major importance. We assessed the 5-year structural and functional integrity outcomes following trans-catheter aortic valve implantation (TAVI) with both self-expandable and balloon-expandable prosthetic valve devices. This study included 450 consecutive patients who underwent TAVI for severe symptomatic aortic stenosis (AS) between September 2008 and December 2011. Data were acquired from a multicenter Israeli registry and the median follow up time was 5.6 years. In 184 patients (40.9%) who survived 5 years, prostheses displayed sustained hemodynamic performance, with average peak and mean aortic valve gradients of 16.2 ± 8.9 and 9.2 ± 6.6 mm Hg, respectively. Late structural valve deterioration was found in 22 (12.3%) patients. Of these, 16 (8.9%) experienced valve deterioration and 6 (3.3%) experienced valve failure. Among the 6 patients with bioprosthetic valve failure, only 3 underwent re-interventions. Bioprosthetic valve dysfunction occurred more frequently in patients with small valves (23 mm) and high peak and mean transvalvular gradients at baseline. In conclusion, a relatively low rate of valve deterioration or failure was noted in our long-term follow-up study after TAVI procedures with both the catheter-based self-expandable and balloon-expandable prosthetic valves.

Background Head and neck pain is an atypical presentation of acute aortic dissection. Classic teaching associates this pain with proximal dissections, but this has not been extensively studied. Methods Patients enrolled in the International Registry of Acute Aortic Dissection from January 1996 to March 2015 were included in this study. We analyzed the demographics, presentation, treatment, and outcomes of Type A aortic dissection patients presenting with head and neck pain (n = 812, 25.8%) and compared it with those without these symptoms (n = 2,341, 74.2%). Results Patients with head and neck pain were more likely to be white, female, with a family history of aortic disease. Patients with head and neck pain had higher percentages of back pain (43.3% vs. 37.5%, p = 0.005) and chest pain (87.6% vs. 79.3%, p 65 years were significantly associated with increased mortality. Conclusion Presence of head and neck pain in Type A dissection is associated with more arch involvement, intramural hematoma, and stroke. When isolating those with head and neck pain only, there appear to be a higher rate of comorbidity burden and higher overall mortality.

Objective: Bicuspid aortic valve is a common risk factor for thoracic aortic aneurysm and dissection. Guidelines for elective ascending aortic intervention (AAI) in bicuspid aortic valve are derived from limited evidence, and the extent of practice variation due to patient and provider characteristics is unknown. Using data from 2 large cardiovascular registries, we investigated factors that influence decisions for AAI. Methods: All bicuspid aortic valve cases with known aortic diameters and surgical status were included. We used multivariable logistic regression to profile predictors of isolated aortic valve replacement (AVR) or AVR+AAI, stratified by patient characteristics, surgical indications, and institution. Results: We studied 2861 subjects at 18 institutions from 1996 to 2015. The median aortic diameter of patients who underwent AVR+AAI varied widely across institutions (39-52 mm). Aortic diameters were
