International audience; This document represents the first update of the Cardiothoracic and Vascular Anaesthesia Fellowship Curriculum of the European Association of Cardiothoracic Anaesthesiology and Intensive Care. After obtaining feedback from exit interviews with fellows in training, graduate fellows, and program directors, 2 modified online Delphi procedures with questionnaires were conducted. A consensus was reached when two-thirds of responding committee members gave green or yellow ratings on a traffic light system, and >70% indicated strong agreement or agreement on a 5-point Likert scale. The new regulations include the following: (1) more flexibility in the fellows` rotation, as long as the total number of days, rotations, and cases are completed during the training year; (2) recommendation for strict compliance with national working-time guidelines; (3) no extension of fellowship training to compensate for annual and/or sick leave, unless the required minimum number of cases and rotations are not reached; (4) interruption of fellowship training for >12 months is allowed for personal or medical reasons; (5) introduction of a checklist for quantitative assessment of standard clinical skills; (6) recommendations for a uniform structure of exit interviews; (7) possibility of a 1-month training rotation in a postanesthesia care unit instead of an intensive care unit; and (8) provided all other requirements have been met, the allowance of progression from the basic training year to the advanced fellowship training year without first passing the transesophageal echocardiography examination.

Contains fulltext : 244115.pdf (Publisher’s version ) (Closed access) The novel coronavirus pandemic has radically changed the landscape of normal surgical practice. Lifesaving cancer surgery, however, remains a clinical priority, and there is an increasing need to fully define the optimal oncologic management of patients with varying stages of lung cancer, allowing prioritization of which thoracic procedures should be performed in the current era. Healthcare providers and managers should not ignore the risk of a bimodal peak of mortality in patients with lung cancer; an imminent spike due to mortality from acute coronavirus disease 2019 (COVID-19) infection, and a secondary peak reflecting an excess of cancer-related mortality among patients whose treatments were deemed less urgent, delayed, or cancelled. The European Association of Cardiothoracic Anaesthesiology and Intensive Care Thoracic Anesthesia Subspecialty group has considered these challenges and developed an updated set of expert recommendations concerning the infectious period, timing of surgery, vaccination, preoperative screening and evaluation, airway management, and ventilation of thoracic surgical patients during the COVID-19 pandemic.

International audience; Pediatric cardiac anesthesia is a subspecialty of cardiac and pediatric anesthesiology dedicated to the perioperative care of patients with congenital heart disease. Members of the Congenital and Education Subcommittees of the European Association of Cardiothoracic Anaesthesiology and Intensive Care (EACTAIC) agreed on the necessity to develop an EACTAIC pediatric cardiac anesthesia fellowship curriculum. This manuscript represents a consensus on the composition and the design of the EACTAIC Pediatric Cardiac Anesthesia Fellowship program. This curriculum provides a basis for the training of future pediatric cardiac anesthesiologists by clearly defining the theoretical and practical requirements for fellows and host centers.

The European Association of Cardiothoracic Anaesthesiology (EACTA) and the Society of Cardiovascular Anesthesiologists (SCA) aimed to create joint recommendations for the perioperative management of patients with suspected or proven severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection undergoing cardiac surgery or invasive cardiac procedures. To produce appropriate recommendations, the authors combined the evidence from the literature review, reevaluating the clinical experience of routine cardiac surgery in similar cases during the Middle East Respiratory Syndrome (MERS-CoV) outbreak and the current pandemic with suspected coronavirus disease 2019 (COVID-19) patients, and the expert opinions through broad discussions within the EACTA and SCA. The authors took into consideration the balance between established procedures and the feasibility during the present outbreak. The authors present an agreement between the European and US practices in managing patients during the COVID-19 pandemic. The recommendations take into consideration a broad spectrum of issues, with a focus on preoperative testing, safety concerns, overall approaches to general and specific aspects of preparation for anesthesia, airway management, transesophageal echocardiography, perioperative ventilation, coagulation, hemodynamic control, and postoperative care. As the COVID-19 pandemic is spreading, it will continue to present a challenge for the worldwide anesthesiology community. To allow these recommendations to be updated as long as possible, the authors provided weblinks to international public and academic sources providing timely updated data. This document should be the basis of future task forces to develop a more comprehensive consensus considering new evidence uncovered during the COVID-19 pandemic. ispartof: JOURNAL OF CARDIOTHORACIC AND VASCULAR ANESTHESIA vol:35 issue:7 pages:1953-1963 ispartof: location:United States status: published

Objectives Transcatheter aortic valve replacement (TAVR) has become an alternative treatment for patients with symptomatic aortic stenosis not eligible for surgical valve replacement due to a high periprocedural risk or comorbidities. However, there are several areas of debate concerning the pre-, intra- and post-procedural management. The standards and management for these topics may vary widely among different institutions and countries in Europe. Design Structured web-based, anonymized, voluntary survey. Setting Distribution of the survey via email among members of the European Association of Cardiothoracic Anaesthesiology working in European centers performing TAVR between September and December 2018. Participants Physicians. Measurements and Main Results The survey consisted of 25 questions, including inquiries regarding number of TAVR procedures, technical aspects of TAVR, medical specialities present, preoperative evaluation of TAVR candidates, anesthesia regimen, as well as postoperative management. Seventy members participated in the survey. Reporting members mostly performed 151-to-300 TAVR procedures per year. In 90% of the responses, a cardiologist, cardiac surgeon, cardiothoracic anesthesiologist, and perfusionist always were available. Sixty-six percent of the members had a national curriculum for cardiothoracic anesthesia. Among 60% of responders, the decision for TAVR was made preoperatively by an interdisciplinary heart team with a cardiothoracic anesthesiologist, yet in 5 countries an anesthesiologist was not part of the decision-making. General anesthesia was employed in 40% of the responses, monitored anesthesia care in 44%, local anesthesia in 23%, and in 49% all techniques were offered to the patients. In cases of general anesthesia, endotracheal intubation almost always was performed (91%). It was stated that norepinephrine was the vasopressor of choice (63% of centers). Transesophageal echocardiography guiding, whether performed by an anesthesiologist or cardiologist, was used only ≤30%. Postprocedurally, patients were transferred to an intensive care unit by 51.43% of the respondents with a reported nurse-to-patient ratio of 1:2 or 1:3, to a post-anesthesia care unit by 27.14%, to a postoperative recovery room by 11.43%, and to a peripheral ward by 10%. Conclusion The results indicated that requirements and quality indicators (eg, periprocedural anesthetic management, involvement of the anesthesiologist in the heart team, etc) for TAVR procedures as published within the European guideline are largely, yet still not fully implemented in daily routine. In addition, anesthetic TAVR management also is performed heterogeneously throughout Europe.

Newest 3D software allows measurements directly in the en-face-3D TEE mode. Aim of the study was to ascertain whether measurements performed in the en-face-3D TEE mode are comparable with conventional measurement methods based on 2D TEE and 3D using the multiple plane reconstruction mode with the Qlab® software. En-face-3D TEE is used more frequently in daily clinical routine during cardiac operations. So far measurements could only be done based on 2D images or with the use of multi planar reconstruction mode with additional software. Measurement directly in the 3D image (en-face-3D TEE) would make measurements faster and easier to use in clinical practice. After approval by the local ethic committee and written informed consent from the patients additionally to a comprehensive perioperative 2D TEE examination a real time (RT) 3D zoom- dataset was recorded. Routine measurements of the length of anterior and posterior mitral valve leaflets as well as mitral valve and aortic valve areas were performed in en-face-3D TEE, multiplanar reconstruction mode using Qlab®-software (Philips, Netherlands) and 2D TEE standard views. Twenty nine patients with a mean age of 67 years undergoing elective cardiac surgery/interventions were enrolled in this study. Direct measurements in en-face-3D TEE mode lead to non significant underestimation of all parameters as compared to Qlab® and 2D TEE measurements. Measurements in en-face-3D TEE are feasible but lead to non significant underestimation compared to measurements performed with Qlab® or in 2D TEE views.

This article reviews fellowship training in adult cardiac, thoracic, and vascular anesthesia and critical care from the perspective of European program initiators and educational leaders in these subspecialties together with current training fellows. Currently, the European Association of Cardiothoracic Anaesthesiology (EACTA) network has 20 certified fellowship positions each year in 10 hosting centers within 7 European countries, with 2 positions outside Europe (Sao Paulo, Brazil). Since 2009, 42 fellows have completed the fellowship training. The aim of this article is to provide an overview of the rationale, requirements, and contributions of the fellows, in the context of the developmental progression of the EACTA fellowship in adult cardiac, thoracic, and vascular anesthesia and critical care from inception to present. A summary of the program structure, accreditation of host centers, requirements to join the program, teaching and assessment tools, certification, and training requirements in transesophageal electrocardiography is outlined. In addition, a description of the current state of EACTA fellowships across Europe, and a perspective for future steps and challenges to the educational program, is provided. (C) 2019 Elsevier Inc.

Contains fulltext : 225360.pdf (Publisher’s version ) (Closed access) The novel coronavirus has caused a pandemic around the world. Management of patients with suspected or confirmed coronavirus infection who have to undergo thoracic surgery will be a challenge for the anesthesiologists. The thoracic subspecialty committee of European Association of Cardiothoracic Anaesthesiology (EACTA) has conducted a survey of opinion in order to create recommendations for the anesthetic approach to these challenging patients. It should be emphasized that both the management of the infected patient with COVID-19 and the self-protection of the anesthesia team constitute a complicated challenge. The text focuses therefore on both important topics.

This special article summarizes the design and certification process of the European Association of Cardiothoracic Anesthesiology (EACTA) Cardiothoracic and Vascular Anesthesia (CTVA) Fellowship Program.The CTVA fellowship training includes a two-year curriculum at an EACTA-accredited educational facility. Before fellows are accepted into the program, they must meet a number of requirements, including evidence of a valid license to practice medicine, a specialist degree examination in anesthesiology, and appropriate language skills as required in the host centers. The CVTA Fellowship Program has 2 sequential and complementary levels of training-both with a modular structure that allows for individual planning and also takes into account the differing national healthcare needs and requirements of the 36 countries represented in EACTA. The basic training period focuses on the anesthetic management of patients undergoing cardiac, thoracic, and vascular surgery and related procedures. The advanced training period is intended to deepen and to extend the clinical and nontechnical skills that fellows have acquired during the basic training.The goal of the EACTA fellowship is to produce highly trained and competent perioperative physicians who are able to care for patients undergoing cardiac, thoracic, and vascular anesthesia.

Die Echokardiografie erlaubt die Einschatzung der kardialen Anatomie und Funktion. Eine fallspezifischangepasste Herangehensweise an die echokardiografische Untersuchung ist besonders bei hamodynamisch instabilen Patienten essenziell. Standard-Schnittebenen erlauben eine vollstandige Untersuchung und reduzieren die Wahrscheinlichkeit, etwas zu ubersehen. Die transthorakale Echokardiografie (TTE) sollte in der Notfall- und Intensivmedizin die erste Wahl sein. Die transosophageale Echokardiographie (TEE) ist Standard im operativen Bereich. Die 3D-Echokardiografie dagegen ist in spezifischen Situationen sehr wertvoll. Eine schriftliche Dokumentation der Untersuchungsergebnisse ist obligatorisch.

OBJECTIVES Transcatheter aortic valve implantation (TAVI) in patients with low coronary heights is generally denied but is not impossible. Information about these high-risk procedures is sparse. METHODS Since May 2008, data of more than 3000 patients who had TAVI were prospectively collected in the institutional TAVI Karlsruhe registry. Characteristics, peri- and postoperative outcome of patients with low coronary heights of ≤7 mm were analysed according to the Valve Academic Research Consortium-2. RESULTS Eighty-six patients with an average coronary height of 6.4 ± 1.1 mm (mean age 81.0 ± 5.3 years, logistic EuroSCORE I 19.6 ± 13.3%) were treated. TAVI was performed in 72 transfemoral (83.7%) and 14 transapical (16.3%) cases using 44 CoreValve/Evolut R (51.2%), 21 Sapien XT/S3 (24.4%), 14 ACURATE (16.3%), 5 Lotus (5.8%) and 2 Portico (2.3%) prostheses. Ten procedures were valve-in-valve (VinV) TAVI (VinV, 11.6%). The 72-h, 30-day, 1-year and follow-up (3.0 ± 1.6 years) mortality rates were 2.3%, 8.0%, 10.5% and 26.7%, respectively. Within 30 days, 4 cardiac deaths and 3 non-cardiac deaths occurred (4.7% and 3.5%). Three coronary obstructions (3.5%) occurred-2 during VinV TAVI. One patient was connected to extracorporeal circulation that could not be weaned later due to an unsuccessful percutaneous coronary intervention. Another patient, the only conversion (1.2%), required delayed surgical valve replacement. The third patient died of right heart failure after aortic dissection. The procedural success rate was 95.3%. VinV procedures were associated with increased follow-up deaths (P

OBJECTIVES: The complexity of the mitral valve (MV) anatomy and function is not yet fully understood. Assessing the dynamic movement and interaction of MV components to define MV physiology during the complete cardiac cycle remains a challenge. We herein describe a novel semi-automated 4D MV model. METHODS: The model applies quantitative analysis of the MV over a complete cardiac cycle based on real-time 3D transoesophageal echocardiography (RT3DE) data. RT3DE data of MVs were acquired for 18 patients. The MV annulus and leaflets were semi-automatically reconstructed. Dimensions of the mitral annulus (anteroposterior and anterolateral–posteromedial diameter, annular circumference, annular area) and leaflets (MV orifice area, intercommissural distance) were acquired. Variability and reproducibility (intraclass correlation coefficient, ICC) for interobserver and intraobserver comparison were quantified at 4 time points during the cardiac cycle (mid-systole, end-systole, mid-diastole and end-diastole). RESULTS: Mitral annular dimensions provided highly reliable and reproducible measurements throughout the cardiac cycle for interobserver (variability range, 0.5–1.5%; ICC range, 0.895–0.987) and intraobserver (variability range, 0.5–1.6%; ICC range, 0.827–0.980) comparison, respectively. MV leaflet parameters showed a high reliability in the diastolic phase (variability range, 0.6–9.1%; ICC range, 0.750–0.986), whereas MV leaflet dimensions showed a high variability and lower correlation in the systolic phase (variability range, 0.6–22.4%; ICC range, 0.446–0.915) compared with the diastolic phase. CONCLUSIONS: This 4D model provides detailed morphological reconstruction as well as sophisticated quantification of the complex MV structure and dynamics throughout the cardiac cycle with a precision not yet described.

Objective Transapical aortic valve implantation (TAVI) may lead to obstruction of coronary arteries during deployment. To prevent this, it is essential to determine the distance of the coronary ostium to the aortic annulus prior to valve placement. Multidetector computed tomography (MDCT) commonly is used to determine these measurements, but even marginal exposure to contrast agents can result in acute kidney injury in this high-risk group of multi-morbid patients. The aim of the study was to determine the feasibility of real-time 3D transesophageal echocardiography (RT 3D TEE) as the first-choice technique for noninvasive evaluation of the coronary ostium during TAVI. Design Retrospective study. Setting University hospital. Interventions Fifty patients underwent MDCT the evening before surgery. RT 3D TEE was performed intraoperatively before valve deployment. The dataset from both of these examinations was digitally stored and evaluated. MDCT was performed in nonanesthetized patients; however, in the RT 3D TEE group, general anesthesia was established. Measurements and Main Results The distances from the right coronary artery and the left coronary artery ostium were measured retrospectively. Bland-Altman Plots and linear regression analysis showed excellent correlation between the 2 methodologies; intraobserver and interobserver variance were calculated using analysis of variance. Krippendorff's α indicated excellent agreement between the 2 observers (0.96 and 0.98) as well as between RT 3D TEE and MDCT (0.97 and 0.98). Conclusions The observations showed that RT 3D TEE reliably can measure the coronary ostium distance from the aortic annulus. It is feasible and an alternative method for evaluating these measurements and thereby preventing contrast exposure during MDCT, which may jeopardize the safety of patients with pre-existing renal disease.

Iatrogenic injury to the circumflex artery (Cx) due to its close proximity to the mitral annulus is a rare but dreadful complication that can occur during mitral valve repair. The aim of our study was to compare multiple measurements of the Cx datasets, obtained by real time three-dimensional transesophageal echocardiography (RT3D TEE) and corresponding measurements assessed in multi-planar three-dimensional images acquired by multidetector computed tomography (MDCT). Preoperative RT3D TEE and MDCT datasets of 25 patients who had previously undergone minimally invasive mitral valve surgery were retrospectively analyzed. The vessel diameter and the horizontal as well as vertical distances from the center of the Cx to the mitral valve annulus were measured. Horizontal as well as vertical Cx distances showed a strong correlation between measurements of RT3D TEE and MDCT whereas the measurements of the Cx diameter showed no correlation. Measurements of horizontal and vertical distances of the Cx to the mitral annulus can be performed using RT3D TEE and show good correlation with MDCT-based measurements.

Hintergrund Die umfassende intraoperative transosophageale Echokardiographie (TEE) bezieht zahlreiche quantitative Messungen der Herzkammern und -klappen, basierend auf mehreren Standardschnitten, in die Untersuchung ein. Aufgrund von Zeitmangel beschranken sich die Untersucher in den meisten deutschen Zentren wahrend kardiochirurgischer Engriffe allerdings auf eine problemfokussierte intraoperative Untersuchung, die es nicht erlaubt, das gesamte Repertoire auszuschopfen. Ziel der vorgestellten Studie war es: 1) zu untersuchen, welche Parameter an einem „Real-time-3-dimensional-full-volume“-(RT-3D-FV)-Datensatz gemessen werden konnen, und 2) diese Messungen mit denen aus den 2D-Standardschnitten zu vergleichen.

In the last 10 years, implantation of ventricular-assist devices has become an interesting option as either bridge-to-transplantation or destination procedure for patients with end-stage congestive heart failure. In the future, the number of ventricular assist device implantations is expected to increase furthermore. In general, this patient cohort is associated with significant co-morbidities, for example, pulmonary hypertension, peripheral vascular disease and renal insufficiency. Anaesthetic management for implantation of ventricular assist devices can be challenging for cardiac anaesthesiologists. Even minor changes in their haemodynamics and physiological parameters can cause significant morbidity and mortality. Experience in haemodynamic monitoring including echocardiography and pharmacological management (use of inotropes, phosphodiesterase inhibitors and vasopressors) is a requirement. Particularly, the diagnosis and therapy of right-sided heart failure after implantation of left-ventricular assist devices should be addressed.

Background Injury to the circumflex artery after mitral valve (MV) repair or replacement is a recognized complication of this procedure. We designed an echocardiographic method to visualize the course and flow of the circumflex artery, to detect iatrogenic injury to this structure intraoperatively, as well as to predict the coronary dominance pattern in MV surgery patients. Methods After Ethics Committee approval, a prospective study was undertaken in 110 patients undergoing minimal invasive MV repair. Intraoperative transesophageal echocardiography was used to visualize the circumflex artery using a combination of B-mode imaging and color Doppler with different Nyquist limits. The course of the circumflex artery and the coronary sinus and their corresponding diameters were documented at the proximal and distal ends of both vessels. Preoperative angiographic data were used to determine the coronary dominance type. Results The course of the circumflex artery could be detected proximally in 109 patients (99%), to the point of intersection with the coronary sinus in 99 patients (90%), and distal to this intersection in 95 patients (86%) using our technique. Three patients had evidence of iatrogenic aliasing (circumflex stenosis) or "no flow" (circumflex occlusion) on transesophageal echocardiography examination after repair and therefore underwent surgical or percutaneous correction. All 3 of these patients had an uncomplicated postoperative course thereafter with no evidence of perioperative myocardial infarction. All remaining patients with normal circumflex examinations after repair did not show any clinical evidence of myocardial infarction or unstable hemodynamics postoperatively. The 95% confidence interval for the diameter of the proximal circumflex artery was 4.5 mm to 5.6 mm for the left dominant type patients and 3.8 mm to 4.2 mm for the right dominant and balanced type patients ( p = 0.01). Conclusions The early recognition of iatrogenic injury of the circumflex artery is feasible with intraoperative transesophageal echocardiography examination, and may lead to treatment before extensive myocardial infarction occurs. We suggest that visualization of the circumflex artery with our technique should be performed more frequently in patients undergoing MV surgery.

Background The reoperative risk for degenerated aortic valve xenografts may be increased in elderly patients with comorbidities. We evaluated the off-pump beating heart concept of transapical aortic valve implantation using the valve-in-valve (VinV) concept. Methods Since March 2007, 11 patients with degenerated xenografts received transapical aortic valve implantation using the Edwards Sapien transcatheter heart valve (Edwards Lifesciences, Irvine, CA). After informed consent, all procedures were performed as an off-label use. Mean patient age was 78 ± 6 years (range, 72 to 89), mean logistic European System for Cardiac Operative Risk Evaluation was 32% ± 16% (range, 16% to 62%) and mean Society for Thoracic Surgeons score was 7% ± 3% (range, 3% to 10%). Results All patients were treated off pump. The transapical aortic valve implantation was successful in all patients, and apical access was uncomplicated in all of them. Total operating room time was 71 ± 14 minutes. On postoperative echocardiography, there was no paravalvular incompetence in any and mild (first degree) central incompetence in 2 of 11 patients. Sufficient flaring of the inflow and outflow parts of the Sapien prosthesis was observed in all patients, suggesting a stable position and an almost absent risk of late embolization. Maximal transvalvular pressure gradients were 21 ± 8 mm Hg, and mean echocardiographic pressure gradients were 11 ± 4 mm Hg. Follow-up extends to 330 ± 293 days (range, 15 to 1,007), and all patients are well and alive. Conclusions Valve-in-valve implantation is a truly minimally invasive procedure for redo treatment of failed aortic valve xenografts in high-risk elderly patients. The Edwards Sapien valve is well suited for VinV implantation, and this technique may become a routine procedure to treat degenerated xenografts in the future.

Objective The purpose of this study was to review the management of anesthesia for transapical transcatheter aortic valve implantation. Design Retrospective review of collected data. Setting University-affiliated heart center. Participants One hundred consecutive patients with severe aortic stenosis. Interventions General anesthesia followed by an established fast-track protocol. Materials and Methods A total of 100 patients with significant AS received transapical transcatheter aortic valve implantation. The patients were treated following a fast-track protocol. The mean arterial pressure was maintained above 65 mmHg by volume and/or inotropes during the procedure. The mean arterial pressure was increased above 75 mmHg to avoid hemodynamic deterioration before starting rapid ventricular pacing for the balloon valvuloplasty and the valve implantation. Transesophageal echocardiography was used to assess valve size and for hemodynamic monitoring. Eighty-one patients were treated completely off pump. There was a significant decline in mean arterial pressure from pre- to postvalvuloplasty (74.7 ± 9.1 mmHg v 63.6 ± 11.3 mmHg, p Conclusion A well-designed anesthetic plan as well as an understanding of the surgical procedure and the hemodynamic effects of rapid ventricular pacing are required to ensure successful outcomes in this new surgical option for high-risk patients.

Background Mitral valve (MV) annuloplasty is an integral part of MV repair, but sizing under direct vision is occasionally challenging. Furthermore, traditional sizing is not possible for percutaneous MV repair techniques. This study compared augmented reality-enhanced three-dimensional (3D) transesophageal echocardiography (TEE) for determining MV annuloplasty size with conventional surgical sizing. Methods In patients undergoing elective MV repair, a 3D MV reconstruction was performed using TEE. Modified 4D valve assessment software was used to create 3D computer-aided design models of standard annuloplasty rings (28 to 36 mm), which were stored in a digital database. These virtual 3D annuloplasty ring templates were superimposed on the preoperative 3D TEE reconstructions of the MV, and results were compared with conventional sizing under direct vision. A post hoc validation of the 3D models was performed using the implanted rings as a control. The echocardiographer was blinded to the implanted ring size. Results The study included 50 patients. The correlation between the selected 3D annuloplasty ring template and the implanted annuloplasty ring size was 0.83. Thirty ring templates (60%) were the same size as the implanted annuloplasty ring, 19 templates (38%) differed by ±2 mm in size, and 1 template differed by +4 mm. Postoperatively, the validation protocol revealed a correlation of 0.94 between the size of the ring templates and the implanted annuloplasty prostheses. Conclusions Augmented reality-enhanced TEE for determining optimal annuloplasty ring size during MV repair correlates well with conventional surgical sizing and may facilitate future percutaneous MV repair techniques.

Echocardiography allows assessment of cardiac anatomy and function. A tailored approach to echocardiographic assessment is essential in hemodynamic unstable patients. Standard views allow comprehensive examination and also reduce the chances to oversee unexpected findings. TTE should be first choice in emergency and intensive care medicine. TEE is standard of care in intraoperative setting. 3 D echocardiography is valuable in specific situations. Written reporting of examination is mandatory.

Introduction: Transapical-aortic valve implantation (TA-AVI) has evolved into a routine procedure in selected elderly high-risk patients. However, more-than-mild paravalvular leaks remain a significant drawback of current TAVI systems. The aim was to study the impact of native aortic valve calcification on paravalvular leaks in cardiac contrast-enhanced computed tomography (CT). Methods: The degree and distribution of native valve calcification were quantified using an Aortic Valve Calcium Score (AVCS) for each cusp separately (3mensio Valves™ workstation, version 7.0, 3mensio Medical Imaging B.V., Netherlands). To exclude an artificial increase of the AVCS due to the presence of contrast material, we used a threshold for density [mean aortic density + 2*D] and volume [0, 3, 5, 25 and 50 mm 3 ] of calcification. AVCS was compared to the rate of paravalvular leaks, assessed intraoperatively by echocardiography and root angiography. Results: Eighty-eight consecutive patients prior to TA-AVI with preoperative CT aged 80.0 ± 5.7 years, 51.1 % female were included. Three prosthesis sizes were used for annular diameters up to 23 mm (n = 29), 26 mm (n = 45) and 29 mm (n = 14). Mean log. EuroSCORE was 24.6 ± 15.4 % and mean STS-Score was 8.4 ± 8.3 %. The mean AVCS in patients without paravalvular leaks (n = 42) was 606.4 ± 374.3; with mild paravalvular leaks (n = 39) was 761.2 ± 530.4; and with moderate paravalvular leaks (n = 5) was 792.4 ± 515.3 with the highest calcification in the non-coronary cusp. There was no significant association between the total AVCS and paravalvular leaks (χ 2 -statistic = 2.9; P = 0.13, 551 hounsfield units). The additional use of the volume-based threshold did not lead to an increase of the association between the AVCS and paravalvular leakages. Paravalvular leaks were significantly associated with the degree (r Spearman = 0.34; χ 2 -statistic = 10.0; P = 0.02) and location of eccentric calcified plaques. Conclusions: Quantification of aortic valve calcification in contrast enhanced computed tomography shows only a weak correlation with paravalvular leakage and is therefore not reliable as a predictor, respectively. The degree of eccentric cusp calcification was significantly associated with the occurrence and location of paravalvular leaks.

Objective The purpose of the study was to report the anesthetic management and immediate procedural success in the initial 20 patients undergoing percutaneous transapical mitral valve replacement. Design Retrospective review of collected data. Setting University-affiliated heart center. Participants Twenty patients with mitral regurgitation or stenosis due to a degenerated valve or ring in the mitral position. Interventions TEE-guided transapical mitral valve replacement under general anesthesia and early extubation by means of an established fast-track protocol. Measurements and Main Methods Twenty patients underwent transapical mitral valve replacement by a beating heart procedure, avoiding cardiopulmonary bypass. The valve was either deployed due to a previously implanted bioprosthetic valve (valve-in-valve group), which degenerated, or a ring (valve-in-ring group), which predominantly showed regurgitation. There was a significant increase in the mitral valve opening area in stenosed valve pathology from 1.3-1.9 sq. cm (p = 0.004), and an increase in ejection fraction from 40% to 45% (p = 0.52). In the valve-in-ring group, valve area increased from 2.0 sq. cm to 2.6 sq. cm (p = 0.21), with an increase in ejection fraction from 30% to 35% (p = 0.18). Eighteen patients underwent successful deployment of the valve. The anesthesia duration for the procedure lasted 185.5±25.4 minutes. Conclusions There was a significant increase in opening area of the valve and improvement in ejection fraction in this patient group. TEE and fluoroscopy-guided imaging is necessary for the procedure’s success and is an evolving alternative treatment for high-risk mitral valve patients who would otherwise be considered inoperable for routine surgery using sternotomy.

Circumflex artery occlusion is an unusual but grave complication that can be intra-operatively challenging to identify. Various modalities of imaging are possible during transfemoral aortic valve replacement (TAVR). Fluoroscopy and/or trans-esophageal echocardiography maybe used for assessment during and after TAVR. Imaging dilemma can cause delay or alter diagnosis. We report a case of an imaging complication during TAVR which might have modified the outcome of the procedure.

A frail 77-year-old man with severe aortic stenosis (Pmax/Pmean gradient of 67/34 mmHg, aortic valve area 0.8 cm2) underwent a valuable bailout strategy in the case of valve dislocation of the Sapien™ prosthesis into the left ventricle (LV) during transapical aortic valve implantation. Major comorbidities included coronary three-vessel disease status post-bare-metal stent implantation (Coroflex®, B. Braun, Melsungen, Germany), status post-multiple myocardial …

Aim of our study was to evaluate the beneficial effect of low dose intrathecal morphine on postoperative analgesia, over the use of intravenous patient controlled anesthesia (PCA), in patients undergoing fast track anesthesia during minimally invasive cardiac surgical procedures. A randomized controlled trial was undertaken after approval from local ethical committee. Written informed consent was obtained from 61 patients receiving mitral or tricuspid or both surgical valve repair in minimal invasive technique. Patients were assigned randomly to 2 groups. Group 1 received general anesthesia and intravenous patient controlled analgesia (PCA) pump with Piritramide (GA group). Group 2 received a single shot of intrathecal morphine (1.5 μg/kg body weight) prior to the administration of general anesthesia (ITM group). Site of puncture was confined to lumbar (L1-2 or L2-3) intrathecal space. The amount of intravenous piritramide used in post anesthesia care unit (PACU) and the first postoperative day was defined as primary end point. Secondary end points included: time for tracheal extubation, pain and sedation scores in PACU upto third postoperative day. For statistical analysis Mann-Whitney-U Test and Fishers exact test (SPSS) were used. We found that the demand for intravenous opioids in PACU was significantly reduced in ITM group (P

Vena contracta width (VCW) and effective regurgitant orifice area (EROA) are well established methods for evaluating mitral regurgitation using transesophageal echocardiography (TEE). For color-flow Doppler (CF) measurements Nyquist limit of 50–60 cm/s is recommended. Aim of the study was to investigate the effectiveness of a baseline shift of the Nyquist limit for these measurements. After a comprehensive 2-dimensional (2D) TEE examination, the mitral regurgitation jet was acquired with a Nyquist limit of 50 cm/s (NL50) along with a baseline shift to 37.5 cm/s (NL37.5) using CF. Moreover a real time 3-dimensional (RT 3D) color complete volume dataset was stored with a Nyquist limit of 50 cm/s (NL50) and 37.5 cm/s (NL37.5). Vena contracta width (VCW) as well as Proximal Isovelocity Surface Area (PISA) derived EROA were measured based on 2D TEE and compared to RT 3D echo measurements for vena contracta area (VCA) using planimetry method. Correlation between VCA 3D NL50 and VCW NL50 was 0.29 (p < 0.05) compared to 0.6 (p < 0.05) using NL37.5. Correlation between VCA 3D NL50 and EROA 2D NL50 was 0.46 (p < 0.05) vs. 0.6 (p < 0.05) EROA 2D NL37.5. Correlation between VCA 3D NL37.5 and VCW NL50 was 0.45 (p < 0.05) compared to 0.65 (p < 0.05) using VCW NL37.5. Correlation between VCA 3D NL37.5 and EROA 2D NL50 was 0.41 (p < 0.05) vs. 0.53 (p < 0.05) using EROA 2D NL37.5. Baseline shift of the NL to 37.5 cm/s improves the correlation for VCW and EROA when compared to RT 3D NL50 planimetry of the vena contracta area. Baseline shift in RT 3D to a NL of 37.5 cm/s shows similar results like NL50.

OBJECTIVE: Transapical-aortic valve implantation (TA-AVI) has evolved as routine for selected high-risk patients. However, paravalvular leaks >1+ remain an unsolved issue using current generations of transcatheter valve devices. The purpose of this study was to investigate the impact of native aortic valve calcification on paravalvular leaks and outcomes using the Edwards SAPIEN™ prosthesis. METHODS: One hundred and twenty consecutive patients (out of 307 TA-AVIs) with preoperative computed tomography aged 82.6 ± 6.2 years, 75.0% female were included. Implanted prosthetic valve sizes were 23 mm (n= 31) and 26 mm (n= 89), respectively. Mean logistic European System for Cardiac Operative Risk Evaluation-Score was 30.1 ± 15.5% and mean Society of Thoracic Surgeons-Score was 12.8 ± 7.9%. Electrocardiographic (ECG)-gated cardiac computed tomography allowed to quantify the amount of calcification of aortic valve leaflets using a scoring analogous to the Agatston calcium scoring of coronary arteries [Aortic Valve Calcium Scoring (AVCS)]. Paravalvular leaks were assessed intraoperatively by echocardiography and root angiography. RESULTS: All valves were implanted successfully. The mean AVCS in patients without paravalvular leaks (n= 66) was 2704 ± 1510; with mild paravalvular leaks (n= 31) was 3804 ± 2739 (P= 0.05); and with moderate paravalvular leaks (n= 4) was 7387 ± 1044 (P= 0.002). There was a significant association between the AVCS and paravalvular leaks [odds ratio (OR; per AVCS of 1000), 11.38; 95% confidence interval (CI) 2.33–55.53; P= 0.001)] and a trend towards a higher incidence of new pacemaker implantation (OR 1.27; 95% CI 0.85–1.89; P= 0.26). No association was found to 30-day mortality, major cardiac events and stroke rate (OR 1.05; 95% CI 0.84–1.32; P= 0.68; OR 0.92; 95% CI 0.68–1.25; P= 0.57 and OR 0.90; 95% CI 0.41–1.96; P= 0.79, respectively). Overall 30-day mortality was 14.2%. CONCLUSION: Severe native valve calcifications are predictive for postoperative relevant paravalvular leak. AVCS prior to TA-AVI might serve as an additional tool to reconsider the TAVI indication to reduce the risk of paravalvular leaks especially in so-called operable patients.

Aim of our study was to investigate the feasibility of use and possible additional value of real-time 3D transesophageal echocardiography (RT-3D-TEE) compared to conventional 2D-TEE in patients undergoing elective mitral valve repair. After ethical committee approval, patients were included in this prospective study. After induction of anesthesia, a comprehensive 2D-TEE examination was performed, followed with RT-3D-TEE. The intraoperative surgical finding was used as the gold standard for segmental analysis. Only such segments which were surgically corrected either by resection or insertion of artificial chords were judged pathologic. A total of 50 patients were included in this study; usable data were available from 42 of these patients . Based on the Carpentier classification, the pathology found was type I in 2 (5%) patients, type II in 39 (93%) patients and type IIIb in 1 (2%) patient. We found that 3D imaging of complex mitral disease involving multiple segments, when compared to 2D-TEE did not show any statistically significant difference.RT-3D-TEE did not show any major advantage when compared to conventional 2D-TEE for assessing mitral valve pathology, although further study in a larger population is required to establish the validity of this study.

Aims We sought to investigate the additional value of real-time three-dimensional transoesophageal echocardiography (RT 3D TOE)-guided sizing for predicting annuloplasty ring size during mitral valve repair. Methods and results In 53 patients undergoing elective mitral valve repair, an RT 3D TOE was performed pre- and post-operatively. The digitally stored loops were imported into a software for mitral valve assessment. The annuloplasty ring size was predicted by superimposing computer-aided design (CAD) models of annuloplasty rings onto Live 3D zoom loops, measurement of the intercommissural distance, or the height of the anterior mitral leaflet. The surgeon implanted the annuloplasty ring according to the usual surgical technique and was blinded to the echocardiographic measurement results. Pre-operative correlation between the selected ring size with mitral valve assessment and the actual implanted annuloplasty ring size was 0.91. The correlation for measurement of the intercommissural distance was 0.55 and for measurement of the height of the anterior mitral leaflet 0.75. The post-operative correlation with the actual implanted ring size was 0.96 for mitral valve assessment, 0.92 for intercommissural distance, and 0.79 for the anterior mitral leaflet height. Conclusion Superimposition of annuloplasty ring CAD models on the Live 3D zoom loops of the mitral valve using mitral valve assessment is superior to two-dimensional measurements of the intercommissural distance or the height of the anterior mitral leaflet in predicting correct annuloplasty ring size.

Objective To optimize the conditions for the surgeon during minimally invasive direct coronary artery bypass (MIDCAB) and totally endoscopic coronary artery bypass (TECAB) procedures, one-lung ventilation (OLV) is required using double-lumen tubes (DLT). This prospective study was designed to compare high-frequency jet ventilation (HFJV) of both lungs with the conventional method of OLV via DLT. Design Prospective, randomized, clinical study. Setting University-affiliated heart center. Participants Forty patients with coronary artery disease and scheduled for elective MIDCAB or TECAB procedures were equally randomized into a DLT and an HFJV group. Interventions In the DLT group, OLV of the right lung was performed throughout the surgical procedure. In the HFJV group, patients received a conventional single-lumen endotracheal tube and both lungs were ventilated using HFJV. Measurements Hemodynamic, oxygenation and ventilation parameters were measured at the beginning of the operation, then 5, 15, 30, and 60 minutes after OLV/HFJV, as well as immediately before transfer to the ICU. Main Results Regarding the view of the surgical field, surgeons' comfort did not differ between methods. The intraoperative PaO 2 was significantly higher in the HFJV group compared with the DLT group at 5 (336.8 ± 123.3 v 228.6 ± 124.0; p = 0.009) and 15 minutes (301.7 ± 133.9 v 192.6 ± 92.8; p = 0.012). The PaCO 2 was significantly higher in the HFJV group after 5 minutes and persisted through 60 minutes of ventilation. The peak inspiratory pressure was significantly lower during HFJV (10.0 ± 2.8 mbar v 32.1 ± 5.9 mbar). Conclusions HFJV in MIDCAB or TECAB procedures appears to be a feasible alternative to OLV using a DLT, although study in a larger population is required.

Objective: Compare changes in P-wave amplitude of the intra-atrial electrocardiogram (ECG) and its corresponding transesophageal echocardiography (TEE)-controlled position to verify the exact localization of a central venous catheter (CVC) tip. Design: A prospective study. Setting: University, single-institutional setting. Participants: Two hundred patients undergoing elective cardiac surgery. Interventions: CVC placement via the right internal jugular vein with ECG control using the guidewire technique and TEE control in 4 different phases: phase 1: CVC placement with normalized P wave and measurement of distance from the crista terminalis to the CVC tip; phase 2: TEE-controlled placement of the CVC tip; parallel to the superior vena cava (SVC) and measurements of P-wave amplitude; phase 3: influence of head positioning on CVC migration; and phase 4: evaluation of positioning of the CVC postoperatively using a chest x-ray. Measurements and Main Results: The CVC tip could only be visualized in 67 patients on TEE with a normalized P wave. In 198 patients with the CVC parallel to the SVC wall controlled by TEE (phase 2), an elevated P wave was observed. Different head movements led to no significant migration of the CVC (phase 3). On a postoperative chest-x-ray, the CVC position was correct in 87.6% (phase 4). Conclusion: The study suggests that the position of the CVC tip is located parallel to the SVC and 1.5 cm above the crista terminalis if the P wave starts to decrease during withdrawal of the catheter. The authors recommend that ECG control as per their study should be routinely used for placement of central venous catheters via the right internal jugular vein.

Transapical aortic valve implantation is a minimally invasive, beating-heart procedure that normally requires a general anesthetic. We herein report an 85-year-old patient with impaired pulmonary function who underwent successful transapical aortic valve implantation while awake, using a thoracic epidural anesthetic.
