Virtuosic craft or clerical labour: the rise of the electronic health record and challenges to physicians' professional identity (1950-2022).

The electronic health record (EHR) is a focus of contentious debate, having become as essential to contemporary clinical practice as it is polarising. Debates about the EHR raise questions about physicians' professional identity, the nature of clinical work, evolution of the patient/practitioner relationship, and narratives of technological optimism and pessimism. The metaphors by which clinicians stake our identities-are we historians, detectives, educators, technicians, or something else?-animate the history of the early computer-based medical record in the mid-to-late twentieth-century USA. Proponents and detractors were equally interested in what the EHR revealed about clinician identity, and how it might fundamentally reshape it. This paper follows key moments in the history of the early computer-based patient record from the late 1950s to the EHR of the present day. In linking physician identity development, clinical epistemological structures, and the rise of the computer-based medical record in the USA in the mid-to-late twentieth century, we ask why the EHR is such a polarising entity in contemporary medicine, and situate clinician/EHR tensions in a longer history of aspirational physician identity and a kind of technological optimism that soon gave way to pessimism surrounding computer-based clinical work.

Reversible, regional ST-segment elevation due to chylothorax.

Chylothorax is an uncommon complication of thoracic surgery and, to our knowledge, has never been documented as a cause of dynamic ST-segment elevation (STE). A 63-year-old woman with history of right pneumonectomy presented with chest pain and regional STE on 12-lead electrocardiogram (ECG). Normal troponin-I and a computed tomography (CT) scan showing a large right hemithoracic fluid collection indicated the unique cause of STE, which resolved after thoracentesis, was pericardial inflammation and cardiac compression from chylothorax. This case emphasizes nuances of ECG interpretation in the context of regional STE and explores the pathophysiology that links chylothorax with acute pericarditis.

Patients' Experiences With Staphylococcus aureus and Gram-negative Bacterial Bloodstream Infections: A Qualitative Descriptive Study and Concept Elicitation Phase To Inform Measurement of Patient-reported Quality of Life.

BACKGROUND: Although Staphylococcus aureus and gram-negative bacterial bloodstream infections (SAB/GNB) cause substantial morbidity, little is known regarding patient perceptions' of their impact on quality of life (QOL). Guidance for assessing QOL and disease-specific measures are lacking. We conducted a descriptive qualitative study to gain an in-depth understanding of patients' experiences with SAB/GNB and concept elicitation phase to inform a patient-reported QOL outcome measure. METHODS: We conducted prospective one-time, in-depth, semi-structured, individual, qualitative telephone interviews 6- 8 weeks following bloodstream infection with either SAB or GNB. Patients were enrolled in an institutional registry (tertiary academic medical center) for SAB or GNB. Interviews were audio-recorded, transcribed, and coded. Directed content analysis identified a priori and emergent themes. Theme matrix techniques were used to facilitate analysis and presentation. RESULTS: Interviews were completed with 30 patients with SAB and 31 patients with GNB. Most patients were at or near the end of intravenous antibiotic treatment when interviewed. We identified 3 primary high-level concepts: impact on QOL domains, time as a critical index, and sources of variability across patients. Across both types of bloodstream infection, the QOL domains most impacted were physical and functional, which was particularly evident among patients with SAB. CONCLUSIONS: SAB/GNB impact QOL among survivors. In particular, SAB had major impacts on multiple QOL domains. A combination of existing, generic measures that are purposefully selected and disease-specific items, if necessary, could best capture these impacts. Engaging patients as stakeholders and obtaining their feedback is crucial to conducting patient-centered clinical trials and providing patient-centered care.

Technical aspects of a successful transvascular retrieval of an acutely dislodged WaveCrest® left atrial appendage occluder.

Percutaneous left atrial appendage (LAA) closure is an alternative therapy in patients with atrial fibrillation who are not suitable for anticoagulation. However, device embolization is one of the notable complications which inevitably requires catheter or surgical retrieval. In addition to previously reported Watchman® or AMULET® occluder embolization, here we report the first case of a WaveCrest® occluder dislodgement which was successfully removed by transcatheter technique. Instead of using the well-known snaring technique, we used a "wiring and ballooning technique" for retrieval. Considering its specific architecture without having hooks or feet where suitable for grasping, this technique is an option for retrieving WaveCrest® devices.

Clinical utility of intraprocedural three-dimensional integrated image guided transcatheter aortic valve implantation using novel automated computed tomography software: A single-center preliminary experience.

OBJECTIVES: Novel automated computed tomography (CT) software (Valve ASSIST 2) has been developed for transcatheter aortic valve implantation (TAVI), which not only provides three-dimensional (3D) reconstruction of multidetector (MD) CT images, but also enables intraprocedural real-time fusion of fluoroscopic and MDCT images. We aimed to clarify the reproducibility and accuracy of this software in the aortic annulus assessment and verify the potential of intraprocedural integrated MDCT imaging for TAVI. METHODS AND RESULTS: We examined 50 patients with severe aortic stenosis undergoing transfemoral TAVI. Aortic annulus measurements were performed using 3mensio and the novel planning software. For intraprocedural imaging, preoperative CT dataset was overlaid onto fluoroscopy with the fusion software. The two images were aligned using the aortic root anatomy visible on both modalities. Novel planning software provided excellent reproducibility for the measurement of aortic annulus area (intraobserver intraclass correlation coefficients [ICC] 0.959, interobserver ICC 0.941), and perimeter (intraobserver ICC 0.915, interobserver ICC 0.912). Excellent correlation was found between novel planning software and 3mensio (ICC 0.952 for aortic annulus area, and 0.923 for perimeter). Intraprocedural fusion image of CT aortography and fluoroscopic aortic root aortography generated by this novel software identified coronary orifices and the distribution of aortic valve calcification during the device positioning. Fusion image displayed coronary orifices after device implantation. CONCLUSIONS: Novel planning software showed excellent reproducibility and accuracy in the assessment of aortic root anatomy. Furthermore, the integrated 3D fusion image might have a potential as an intraprocedural imaging modality to contribute to the development of a safer TAVI procedure.

Impact of N-terminal pro-B-type natriuretic peptide response on long-term prognosis after transcatheter aortic valve implantation for severe aortic stenosis and heart failure.

N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels prior to transcatheter aortic valve implantation (TAVI) are known to be associated with outcomes of patients undergoing TAVI. However, little has been known about the NT-proBNP response after TAVI. Therefore, we aimed to clarify the role of the NT-proBNP response and identify the determinants of the NT-proBNP nonresponse among patients with severe aortic stenosis (AS) and heart failure (HF) undergoing TAVI. We examined 717 patients with severe AS and HF undergoing TAVI. NT-proBNP nonresponders were defined as patients whose NT-proBNP levels decreased by ≤ 30%. Mean NT-proBNP levels decreased from 7698 ± 7853 pg/mL (baseline) to 4523 ±  5173 pg/mL (post-TAVI); 269 patients (38%) were nonresponders. Female gender and prevalence of diabetes mellitus (DM), chronic kidney disease (CKD), atrial fibrillation (AF), and history of coronary artery revascularization were more common for NT-proBNP nonresponders. Permanent pacemaker implantation rate was higher for NT-proBNP nonresponders. In addition to the baseline NT-proBNP level > 7500 pg/smL (hazard ratio [HR], 1.8; p = 0.03), NT-proBNP nonresponse (HR 2.3; p = 0.001) was associated with lower survival rates. Baseline NT-proBNP level ≤ 7500 pg/mL (OR 3.2; p < 0.001), female gender (odds ratio [OR], 1.5; p = 0.049), DM (OR 1.6; p = 0.016), CKD (OR 1.8; p = 0.001), AF (OR 2.4; p < 0.001), history of coronary revascularization (OR 1.7; p = 0.003), and permanent pacemaker implantation after TAVI (OR 1.7; p = 0.034) were independent determinants of NT-proBNP nonresponse. In "conclusion", NT-proBNP response is important for long-term survival after TAVI. We should consider the aforementioned determinants, particularly permanent pacemaker implantation, as risk factors for NT-proBNP nonresponse.

Predictors of permanent pacemaker implantation after transcatheter aortic valve implantation for aortic stenosis using Medtronic new generation self-expanding CoreValve Evolut R.

Conduction disturbance requiring permanent pacemaker (PPM) implantation is a common complication after transcatheter aortic valve implantation (TAVI) using Medtronic self-expanding CoreValve, and has remained common following the introduction of the new generation CoreValve Evolut R device. The aim of this study was to identify the determinants of PPM implantation after TAVI with CoreValve Evolut R. We retrospectively examined 114 patients who underwent transfemoral TAVI using CoreValve Evolut R. We excluded 17 patients with preprocedural PPM, 1 patient requiring Edwards SAPIEN 3 implantation after CoreValve Evolut R implantation, and 4 patients who died during the hospital admission. Thus, 92 patients were finally included in the analysis. Seventeen patients (18%) underwent new PPM implantation after TAVI. Preprocedural electrocardiography showed a lower ventricular rate and more right bundle branch block (RBBB) in patients with new PPM implantation compared to those without. Quantitative multidetector computed tomography assessment revealed larger aortic valve calcification (AVC) and higher asymmetry (∆AVC) in patients with new PPM implantation compared to those without. The univariate logistic regression analysis demonstrated that preprocedural ventricular rate ≤ 70 beats per minute, RBBB, AVC ≥ 110 mm3, and ∆AVC ≥ 45 mm3 were associated with new PPM implantation. Number of these factors clearly stratified the risk of new PPM implantation. In conclusion, PPM implantation occurs in 18% of patients undergoing TAVI with the new generation CoreValve Evolut R. Lower preprocedural ventricular rate, RBBB, larger AVC, and higher ∆AVC are associated with new PPM implantation after TAVI using the new generation CoreValve Evolut R.

Bleeding and thrombotic complications of pediatric liver transplant.

BACKGROUND: Pediatric patients undergoing liver transplant are at significant risk for bleeding and thrombotic complications due to the complex nature of rebalanced hemostasis in patients with liver disease. METHODS/OBJECTIVES: We reviewed records of 92 pediatric liver and multivisceral transplant cases at Duke University Medical Center between January 2009 and December 2015. The goal was to define the nature and incidence of bleeding and thrombotic complications in this cohort and define potential risk factors. RESULTS: There were 24 major bleeding events in 19 transplants (incidence 20.7%) and 30 thrombotic events in 23 transplants (incidence 25%). Five of the 10 retransplantations were for vascular thrombotic complications. Thirty-day mortality was 4.9%, and three of these four deaths were due to vascular thrombosis. No bleeding events led to retransplantation or mortality. Prophylactic aspirin was associated with decreased risk of thrombosis without increased bleeding. Prophylactic heparin did not increase bleeding risk. Laboratory assays predicted events poorly, apparently failing to capture the nuanced and dynamic interplay between pro- and anticoagulant factors in the posttransplant patient. CONCLUSIONS: Both bleeding and thrombosis are frequent in this population, but only thrombotic complications contributed to retransplantation and mortality. A standardized approach to coagulation testing and antithrombotic therapy may be useful in predicting and reducing adverse outcomes. Alternative approaches to monitoring hemostasis need to be prospectively investigated in this complex patient population.

MitraClip in Patients With Mitral Regurgitation and Left Ventricular Ejection Fraction <30%　- Potential Implications for the Treatment of Patients in Japan.

BACKGROUND: The effect of the unique Japanese indication for MitraClip based on left ventricular ejection fraction (LVEF) is unclear. Methods and Results: We analyzed 874 patients who underwent MitraClip because of mitral regurgitation (MR) and compared the characteristics and outcomes between patients with LVEF <30% and ≥30%. Patients with LVEF ≤30% accounted for 33% of the study population and had a higher prevalence of functional MR. Severity of MR after MitraClip was comparable, and LVEF <30% did not independently affect survival. CONCLUSIONS: Japanese unique indication based on LVEF may exclude one third of patients who were treated with MitraClip in Europe.

Blood money: Harvey's De motu cordis (1628) as an exercise in accounting.

William Harvey's famous quantitative argument from De motu cordis (1628) about the circulation of blood explained how a small amount of blood could recirculate and nourish the entire body, upending the Galenic conception of the blood's motion. This paper argues that the quantitative argument drew on the calculative and rhetorical skills of merchants, including Harvey's own brothers. Modern translations of De motu cordis obscure the language of accountancy that Harvey himself used. Like a merchant accounting for credits and debits, intake and output, goods and moneys, Harvey treated venous and arterial blood as essentially commensurate, quantifiable and fungible. For Harvey, the circulation (and recirculation) of blood was an arithmetical necessity. The development of Harvey's circulatory model followed shifts in the epistemic value of mercantile forms of knowledge, including accounting and arithmetic, also drawing on an Aristotelian language of reciprocity and balance that Harvey shared with mercantile advisers to the royal court. This paper places Harvey's calculations in a previously underappreciated context of economic crisis, whose debates focused largely on questions of circulation.

Predictors of thrombus formation after percutaneous left atrial appendage closure using the WATCHMAN device.

Percutaneous left atrial appendage (LAA) closure using the WATCHMAN device is a novel option for prevention of stroke associated with atrial fibrillation. However, device-related thrombus (DRT) formation is a concern after WATCHMAN implantation and the predictors of DRT still remain unclear. We aimed to clarify the predictors of DRT after WATCHMAN implantation by analyzing 78 patients (50 males, 72 ± 8 years, average CHA2DS2-VASc score of 4.3 + 1.8) who had undergone WATCHMAN implantation. WATCHMAN was successfully implanted in all patients and four (5%) developed DRT. Patients with DRT were more often female (75 vs. 34%, p = 0.094). CHA2DS2-VASc score was higher for patients with DRT (6.3 ± 2.5 vs. 4.2 ± 1.7, p = 0.022). Chronic kidney disease (100% vs. 43%, p = 0.024) and deep implantation of the device, which was defined as implant position below the LAA ostial plane (75 vs. 24%, p = 0.026), were more common in patients with DRT. HAS-BLED score (4.5 ± 1.0 vs. 3.5 ± 1.1, p = 0.074) was higher and oral anticoagulants (50 vs. 84%, p = 0.086) were less commonly prescribed for patients with DRT. Multivariable logistic regression analysis showed that higher CHA2DS2-VASc score (p = 0.022, OR 2.8) and deep implantation (p = 0.032, OR 24.7) were associated with DRT. These results suggest the possible role of CHA2S2-VASc scores and implantation depth in the development of DRT after percutaneous LAA closure using the WATCHMAN device.

Role of Right Ventricular Dysfunction and Diabetes Mellitus in N-terminal pro-B-type Natriuretic Peptide Response of Patients With Severe Mitral Regurgitation and Heart Failure After MitraClip.

MitraClip (MC) is an alternative therapeutic option for patients with severe mitral regurgitation (MR) who are at high surgical risk. Most candidates for MC have severe heart failure (HF) with increased N-terminal pro-B-type natriuretic peptide (NT-pro BNP) levels. We sought to clarify the response of NT-pro BNP after MC and to identify the determinants of NT-pro BNP nonresponders. Among 136 consecutive patients successfully treated with MC, we excluded 20 patients due to low baseline NT-pro BNP levels and therefore examined 116 patients. NT-pro BNP responders were defined as patients whose NT-pro BNP levels decreased by > 30% at 6 months after MC. Mean NT-pro BNP levels significantly decreased from 6,117 pg/mL at baseline to 4,143 pg/mL at 6 months after MC (P < 0.001); 61 patients (53%) were responders. Diabetes mellitus (DM) (51% versus 25%; P = 0.003) and atrial fibrillation (67% versus 49%; P = 0.049) were more common in nonresponders. Baseline New York Heart Association (NYHA) class and NT-proBNP levels were higher in responders. Right ventricular systolic dysfunction (RVSD) defined as tricuspid annular plane systolic excursion (TAPSE) < 15 mm was more common in nonresponders (41% versus 18%; P = 0.008). Multivariable logistic regression analysis revealed that DM (odds ratio [OR], 2.966; P = 0.014), RVSD (OR, 3.948; P = 0.006), and baseline NT-proBNP > 5,000 pg/mL (OR, 0.204; P = 0.001) were independent determinants of nonresponders. All-cause death tended to be less common in responders to NT-pro BNP (20% versus 31%; P = 0.163). In conclusion, NT-pro BNP levels significantly decreased after MC. DM and RVSD were determinants of NT-pro BNP nonresponse after the MC procedure.

Impact of left ventricular systolic dysfunction on the outcomes of percutaneous edge-to-edge mitral valve repair using MitraClip.

Left ventricular systolic dysfunction (LVD) is associated with poor outcomes after mitral regurgitation (MR) surgery. MitraClip (MC) is a novel treatment option for MR patients with a high surgical risk. However, outcomes of LVD patients underwent MC remain unclear. In total of 194 patients after MC implantation, 75 patients (39 %) had severe LVD (LV ejection fraction ≤30 %). Patients with severe LVD were primarily male and also younger. Logistic euroSCOREs were comparable between the two groups. Functional MR was more common in patients with severe LVD, while New York Heart Association (NYHA) class was similar between the two groups. N-terminal pro-B-type natriuretic peptide (NT-proBNP) was significantly higher in patients with LVD. In addition to similar improvements in MR severity, NYHA class, and NT-proBNP levels, the survival rates were not different between patients with and without severe LVD. Among patients with severe LVD, the long-term survival rates were significantly lower in patients aged ≥75 years, those with NT-proBNP >5000 pg/mL, and those with atrial fibrillation (AF). In conclusion, severe LVD was not associated with the mortality after MC implantation. MC might be feasible and effective even in the patients with severe MR and low LVEF. However, we need to carefully observe severe LVD patients who are elderly, have a high NT-proBNP level, and have AF, as these might be considered high-risk subjects.

Implementing a breast cancer registry and treatment plan/summary program in clinical practice: a pilot program.

BACKGROUND: There is a need to better measure and improve the quality of oncology care and improve communication with patients and other providers. The American Society of Clinical Oncology Breast Cancer Registry (BCR) pilot evaluated the feasibility and acceptability of prospective data collection for quality assessment in daily clinical practice. Data were used to create and share treatment plans/summaries (TPSs) at the point of care. METHODS: Using a web-based tool, 20 diverse practices entered clinical data on each new early-stage breast cancer patient into the BCR for 14 months (September 2009 through November 2010). The tool created individual TPSs that were shared with patients. Practices received practice-specific and aggregate BCR quality measures data, participated in a survey, and received a participation stipend. RESULTS: Twenty practices entered 2014 patients into the BCR, collecting demographic, clinical, and treatment information. Fifty-two percent of practice participants replied to an end-of-pilot survey: 73% were satisfied with the BCR and web-based tool, 31% expressed concern regarding time and effort, and 52% reported additional practice costs during the pilot. Among those who created or shared the TPSs, 90% thought the documents improved oncologist-patient communication, and 95% favored using BCR data for practice quality improvement. CONCLUSIONS: Prospective data collection for quality assessment is feasible and allows sharing of TPSs with patients at the point of care. Future efforts should focus on decreasing implementation burden to practices, broadening participation, examining costs, and, most importantly, assessing its effects on patient outcomes.

Impact of Transcatheter Edge-to-Edge Mitral Valve Repair on Guideline-Directed Medical Therapy Uptitration.

BACKGROUND: Guideline-directed medical therapy (GDMT) optimization is mandatory before transcatheter edge-to-edge mitral valve repair (M-TEER) in patients with secondary mitral regurgitation (SMR) and heart failure (HF) with reduced ejection fraction (HFrEF). However, the effect of M-TEER on GDMT is unknown. OBJECTIVES: The authors sought to evaluate frequency, prognostic implications and predictors of GDMT uptitration after M-TEER in patients with SMR and HFrEF. METHODS: This is a retrospective analysis of prospectively collected data from the EuroSMR Registry. The primary events were all-cause death and the composite of all-cause death or HF hospitalization. RESULTS: Among the 1,641 EuroSMR patients, 810 had full datasets regarding GDMT and were included in this study. GDMT uptitration occurred in 307 patients (38%) after M-TEER. Proportion of patients receiving angiotensin-converting enzyme inhibitors/angiotensin receptor blockers/angiotensin receptor-neprilysin inhibitors, beta-blockers, and mineralocorticoid receptor antagonists was 78%, 89%, and 62% before M-TEER and 84%, 91%, and 66% 6 months after M-TEER (all P < 0.001). Patients with GDMT uptitration had a lower risk of all-cause death (adjusted HR: 0.62; 95% CI: 0.41-0.93; P = 0.020) and of all-cause death or HF hospitalization (adjusted HR: 0.54; 95% CI: 0.38-0.76; P < 0.001) compared with those without. Degree of MR reduction between baseline and 6-month follow-up was an independent predictor of GDMT uptitration after M-TEER (adjusted OR: 1.71; 95% CI: 1.08-2.71; P = 0.022). CONCLUSIONS: GDMT uptitration after M-TEER occurred in a considerable proportion of patients with SMR and HFrEF and is independently associated with lower rates for mortality and HF hospitalizations. A greater decrease in MR was associated with increased likelihood for GDMT uptitration.

Sex-specific impact of anthropometric parameters on outcomes after transcatheter edge-to-edge repair for secondary mitral regurgitation.

BACKGROUND: Body surface area (BSA) has been reported to be the stronger predictor for prognosis than body mass index in heart failure (HF) patients. The sex-specific association of BSA with mortality has been unclear. METHODS: EuroSMR, a European multicenter registry, included patients who underwent edge-to-edge repair (TEER) for secondary mitral regurgitation (SMR). The outcome was two-year all-cause mortality. RESULTS: The present cohort included 1594 HF patients (age, 74 ± 10 years; male, 66%). Association of calculated BSA with two-year all-cause mortality was evaluated. Patients were classified into three BSA groups: the lowest 10% (S), the highest 10% (L), and intermediate between S and L (M). Mean BSA was 1.87 ± 0.21 m2 (male, 1.94 ± 0.18 m2; female, 1.73 ± 0.18 m2). The association of BSA with the endpoint in females showed a U-shaped curve, indicating worse prognosis for both S and L. The association in males followed a linear regression, demonstrating better prognosis for L. Hazard ratio (HR) of L to S in males was 0.43 (95% confidence interval [CI], 0.25-0.74; p = 0.002), whereas HR of L to M in females was 1.76 (95% CI, 1.11-2.78; p = 0.016) (p for interaction = 0.003). CONCLUSIONS: Sex-specific association patterns demonstrate the complex influence of anthropomorphic factors in HF patients scheduled for TEER. Further investigation beyond simple evaluation of weight and height is needed for better comprehension of the obesity paradox and better prediction of the results of transcatheter therapy in HF patients.

Staging Heart Failure Patients With Secondary Mitral Regurgitation Undergoing Transcatheter Edge-to-Edge Repair.

BACKGROUND: Secondary mitral regurgitation (SMR) is a progressive disease with characteristic pathophysiological changes that may influence prognosis. Although the staging of SMR patients suffering from heart failure with reduced ejection fraction (HFrEF) according to extramitral cardiac involvement has prognostic value in medically treated patients, such data are so far lacking for edge-to-edge mitral valve repair (M-TEER). OBJECTIVES: This study sought to classify M-TEER patients into disease stages based on the phenotype of extramitral cardiac involvement and to assess its impact on symptomatic and survival outcomes. METHODS: Based on echocardiographic and clinical assessment, patients were assigned to 1 of the following HFrEF-SMR groups: left ventricular involvement (Stage 1), left atrial involvement (Stage 2), right ventricular volume/pressure overload (Stage 3), or biventricular failure (Stage 4). A Cox regression model was implemented to investigate the impact of HFrEF-SMR stages on 2-year all-cause mortality. The symptomatic outcome was assessed with New York Heart Association functional class at follow-up. RESULTS: Among a total of 849 eligible patients who underwent M-TEER for relevant SMR from 2008 until 2019, 9.5% (n = 81) presented with left ventricular involvement, 46% (n = 393) with left atrial involvement, 15% (n = 129) with right ventricular pressure/volume overload, and 29% (n = 246) with biventricular failure. An increase in HFrEF-SMR stage was associated with increased 2-year all-cause mortality after M-TEER (HR: 1.39; CI: 1.23-1.58; P < 0.01). Furthermore, higher HFrEF-SMR stages were associated with significantly less symptomatic improvement at follow-up. CONCLUSIONS: The classification of M-TEER patients into HFrEF-SMR stages according to extramitral cardiac involvement provides prognostic value in terms of postinterventional survival and symptomatic improvement.

Rotational angiography for preinterventional imaging in transcatheter aortic valve implantation.

OBJECTIVE: To evaluate the clinical value of 3D rotational angiography, as a tool for imaging and measuring 3D anatomy, coupled with transesophageal echocardiogram (TEE) as preinterventional imaging for transcatheter aortic valve implantation (TAVI) procedures. BACKGROUND: TAVI is a growing field in cardiology. An understanding of the 3D anatomy of the aortic root is crucial for patient selection and for the optimal planning and guidance of such procedures. Current techniques include 3D imaging (with MSCT MRI and 3D TEE) combined with multiplane TEE. Nevertheless, a gold standard of 3D imaging is yet not defined. 3D rotational angiography provides 3D anatomy information in the cathlab. Initially designed for nonmoving anatomical structures, one can adapt the protocol to temporarily minimize the heart anatomy motion during rotational angiography. METHODS: Ninety-nine consecutive patients (61 females, 38 males, age 80.9 ± 5.2 years) with symptomatic aortic stenosis underwent 3D rotational angiography to assess the anatomical suitability of potential TAVI candidates. 3D rotational angiography with a C-Arm (Innova 3100(IQ) , GE Healthcare, Chalfont St Giles, UK) was performed to create the 3D anatomy of the aortic root. Coronary angiography and pelvic vessel angiography were performed during the same examination. Measurements of the aortic annulus and the sinotubular junction were made on the 3D cross-sections and were compared to TEE. Radiation dose to the patient was also monitored. RESULTS: In all 99 patients, 3D rotational angiography was performed successfully with good imaging of the aortic root and measurements of the aortic annulus. In patients scheduled for SAPIEN valve implantation, the distances from the annulus to the coronary ostia were also measured. Of 99 patients, 80 subsequently underwent successful implantation. There is a good correlation to the TEE in the measured aortic annulus (22.13 ± 2.09 mm in rotational angio, 21.58 ± 2.09 mm TEE, Spearman r = 0.88, 95% IC [0.83;0.92], P < 0.0001) and sinotubular junction (26.19 ± 2.71 mm in rotational angio, 26.22 ± 2.73 mm TEE, Spearman r = 0.83, 95% IC [0.75;0.88], P < 0.0001). The effective dose is a fraction of the X-ray dose required for multi-slice computed tomography. CONCLUSION: Given that this technology is available in the cathlab at reasonable dose levels, 3D rotational angiography has proven to be a suitable preinterventional 3D imaging modality for TAVI procedures. Together, the raw angiographic data and the reconstructed 3D volume provide all the necessary anatomical information necessary for this procedure, including the measurements.

Prevalence and Predisposing Factors of Non-infectious Cardiac Implantable Electronic Device Lead Masses as Incidental Finding During Transoesophageal Echocardiography: A Retrospective Cohort Study.

Objectives: In this study, we assessed the prevalence and predisposing factors of non-infectious CIED lead masses as incidental finding during transoesophageal echocardiography (TOE). Methods: In a retrospective single centre study, we analysed TOE examinations performed for indications other than infectious endocarditis in 141 patients with CIED. Patients with non-suspicious leads and those with incidental non-infectious lead masses were compared with respect to clinical characteristics, anticoagulation, indication for TOE, and CIED lead characteristics. The odds ratios for non-infectious CIED lead masses were calculated. Results: Non-infectious CIED lead masses were detected in 39 (27.6%) of the 141 patients. They were more often identified on ICD and CRT-D leads compared to pacemaker and CRT-P leads [OR 2.77 (95% CI 1.29-5.95), p = 0.008]. The lifespan of the CIEDs from the first implantation to the index TOE did not differ between both groups. Incidental CIED lead masses were more prevalent in patients who received their device for primary prevention of sudden cardiac death (43.2%) and for resynchronisation (63.6%) but were less prevalent in patients with oral anticoagulation [OR.33 (95% CI.003-1.003), p = 0.048]. Conclusion: Incidental non-infectious CIED lead masses were frequently found in TOE, with highest prevalence in ICD and CRT-D devices implanted for patients with dilated cardiomyopathy. Patients with therapeutic anticoagulation had significantly lower prevalence of CIED lead masses than those without.

Guideline-directed medical therapy in patients undergoing transcatheter edge-to-edge repair for secondary mitral regurgitation.

AIMS: Guideline-directed medical therapy (GDMT), based on the combination of beta-blockers (BB), renin-angiotensin system inhibitors (RASI), and mineralocorticoid receptor antagonists (MRA), is known to have a major impact on the outcome of patients with heart failure with reduced ejection fraction (HFrEF). Although GDMT is recommended prior to mitral valve transcatheter edge-to-edge repair (M-TEER), not all patients tolerate it. We studied the association of GDMT prescription with survival in HFrEF patients undergoing M-TEER for secondary mitral regurgitation (SMR). METHODS AND RESULTS: EuroSMR, a European multicentre registry, included SMR patients with left ventricular ejection fraction <50%. The outcome was 2-year all-cause mortality. Of 1344 patients, BB, RASI, and MRA were prescribed in 1169 (87%), 1012 (75%), and 765 (57%) patients at the time of M-TEER, respectively. Triple GDMT prescription was associated with a lower 2-year all-cause mortality compared to non-triple GDMT (hazard ratio [HR] 0.74; 95% confidence interval [CI] 0.60-0.91). The association persisted in patients with glomerular filtration rate <30 ml/min, ischaemic aetiology, or right ventricular dysfunction. Further, a positive impact of triple GDMT prescription on survival was observed in patients with residual mitral regurgitation of ≥2+ (HR 0.62; 95% CI 0.44-0.86), but not in patients with residual mitral regurgitation of ≤1+ (HR 0.83; 95% CI 0.64-1.08). CONCLUSION: Triple GDMT prescription is associated with higher 2-year survival after M-TEER in HFrEF patients with SMR. This association was consistent also in patients with major comorbidities or non-optimal results after M-TEER.
