Valid and Reproducible Quantitative Assessment of Cardiac Volumes by Echocardiography in Patients with Valvular Heart Diseases-Possible or Wishful Thinking? Diagnostics (Basel) 2023; 13:1359. [PMID: 37046577 PMCID: PMC10093440 DOI: 10.3390/diagnostics13071359] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Revised: 03/24/2023] [Accepted: 04/03/2023] [Indexed: 04/14/2023] Open
Abstract
The analysis of left ventricular function is predominantly based on left ventricular volume assessment. Especially in valvular heart diseases, the quantitative assessment of total and effective stroke volumes as well as regurgitant volumes is necessary for a quantitative approach to determine regurgitant volumes and regurgitant fraction. In the literature, there is an ongoing discussion about differences between cardiac volumes estimated by echocardiography and cardiac magnetic resonance tomography. This viewpoint focuses on the feasibility to assess comparable cardiac volumes with both modalities. The former underestimation of cardiac volumes determined by 2D and 3D echocardiography is presumably explained by methodological and technical limitations. Thus, this viewpoint aims to stimulate an urgent and critical rethinking of the echocardiographic assessment of patients with valvular heart diseases, especially valvular regurgitations, because the actual integrative approach might be too error prone to be continued in this form. It should be replaced or supplemented by a definitive quantitative approach. Valid quantitative assessment by echocardiography is feasible once echocardiography and data analysis are performed with methodological and technical considerations in mind. Unfortunately, implementation of this approach cannot generally be considered for real-world conditions.

Abstract
BACKGROUND Small aortic root is an unexpected incident during surgical aortic valve replacement in which the prosthesis valve size does not match the case being treated. CASE PRESENTATION Two patient-prosthesis mismatches with aortic valve problems underwent surgical aortic valve replacement. Based on calculating the body surface area (BSA) and effective orifice area (iEOA), the selection of prosthesis valve size was determined. When minor aortic root surgery was performed, it was discovered that the procedure of aortic root enlargement had to be conducted. The surgery went smoothly, but both patients had different outputs. The first patient was dead, while the second patient had a better quality of life. DISCUSSION Every surgical aortic valve replacement preparation of aortic root enlargement procedure needs to be prepared for the worst-case scenario. CONCLUSION Aortic root enlargement procedure must be anticipated in aortic valve replacement, especially for the patients with small aortic roots, both isolated and with concomitant valve procedure.

A comparative study of the efficacy of Glidescope versus Macintosh direct laryngoscopy for intubation in pediatric patients undergoing cardiac surgery. Saudi J Anaesth 2021; 15:419-423. [PMID: 34658729 PMCID: PMC8477783 DOI: 10.4103/sja.sja_472_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2021] [Revised: 06/23/2021] [Accepted: 06/24/2021] [Indexed: 11/21/2022] Open
Abstract
Background: The Glidescope is a novel, portable, reusable video laryngoscope that has provided superior laryngeal visualization to facilitate tracheal intubation, especially in the management of difficult airways. In this study, we aimed to compare the efficacy of the Glidescope (video-laryngoscope) against the Macintosh direct laryngoscope. Methods: Fifty patients were randomly selected via simple randomization using computer-generated random numbers, and sorted into two groups of 25 patients: the Glidescope group and the Macintosh group. We included pediatric patients undergoing cardiac surgery for the repair of congenital heart disease. Those with suspected difficult intubation, preterm babies with low body weight, and patients at risk of aspiration were all excluded. Results: Patients’ baseline demographic and clinical characteristics were found to be comparable in the two groups. The mean intubation time was 24.1 ± 13.6 s in the Glidescope group, as compared to 18.1 ± 5.9 s in the Macintosh group. Blade insertion was easy in 92% and 96% of the patients in the Glidescope and Macintosh groups, respectively. Tracheal intubation was considered easy in 84% of the Glidescope group, compared to 92% of the Macintosh group. There was a statistically significant correlation between the ease of tracheal intubation and the used intubation method (rho = –0.35; P = 0.014). Conclusion: Our findings indicate that the Glidescope can be used as an efficient modality for obtaining successful intubations with no complications. Ease of tracheal intubation was the only outcome that was found to be affected by the used modality. Further investigations with proper sample sizes are needed.

Abstract
OBJECTIVES This study was designed to review the ascending aortic diameter of patients undergoing surgery for AAD in China and its influence on prognosis. METHODS In the period between January 2018 and January 2020, 265 patients eligible for analysis of ascending aorta were included in this study. The maximum diameter of the ascending aorta was assessed using preoperative computed tomography (CT) scan for patients. RESULTS The mean diameter of the ascending aorta of the reference population was 48.16 ± 9.37 mm, and the percentage of subjects with an aorta <55 mm was 80.38%. In this study, we found that BMI, hypertension, and bicuspid aortic valve are the main factors affecting the widening of the ascending aorta, and the diameter of the ascending aorta in patients with AAD is negatively correlated with the patient's long-term prognosis. However, there is no significant difference in survival rates among patients with different ascending aortic diameter. CONCLUSIONS Ascending aortas with smaller diameter are also prone to dissection, most of which occur at a lower surgical threshold than recommended by current guidelines. Therefore, the diameter of ascending aorta cannot be used as an independent risk factor for high-risk patients with aortic dissection, but it can be used as an important indicator to evaluate the long-term prognosis of patients.

A critical appraisal of echocardiographic assessment of functional mitral regurgitation. Int J Cardiovasc Imaging 2020; 37:183-196. [PMID: 32851501 PMCID: PMC7878255 DOI: 10.1007/s10554-020-01975-6] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Accepted: 08/17/2020] [Indexed: 12/12/2022]
Abstract
The contradictory findings of recent prospective randomized controlled trials assessing the impact of percutaneous edge-to-edge repair in patients with functional or secondary mitral regurgitation have triggered a lively discussion about an “integrated” echocardiographic approach for grading severity of mitral regurgitation. In the MITRA-FR trial, the COAPT trial and the REDUCE-FMR trial echocardiographic assessment of the severity of mitral regurgitation was consistent with principles set forth by the current echocardiographic guidelines and analysed in its best settings by expert international leaders in the field of echocardiography. However, serious inconsistencies appeared in the presented echocardiographic assessments regarding cardiac output and regurgitant fraction. A new term “disproportionate functional mitral regurgitation” was introduced describing a situation where the increase of effective regurgitant orifice area exceeds the enlargement of the left ventricular end-diastolic volumes. Further discussion resulted in the idea of a “new conceptional framework” for distinguishing “proportionate” and “disproportionate” functional mitral regurgitation. The aim of this viewpoint is to dispute conclusions based on the term “disproportionate” mitral regurgitation. A “disproportionate” FMR is highly questionable because disproportionateness of flow in communication vessels cannot exist. In addition, a proposal of echocardiographic assessment based on a conventional comprehensive transthoracic echocardiography is given to avoid obvious hemodynamic contradictions.

Abstract
BACKGROUND Device complications in complex percutaneous coronary interventions are rare but potentially deadly. Surgical removal is often required. However, an evaluation of surgical therapy beyond case reports is practically not existent. METHODS We prospectively followed all cases of retained guide wires and/or other devices referred to us for surgical removal between 2015 and 2019 and retrospectively searched our database for such cases between 2010 and 2014. RESULTS From 2015 on, eight cases were referred for surgical removal from six different cardiology departments. In the 5 years before, there was not a single case. Six patients were operated emergently. Patients were 60.5 ± 5.42 years old, overweight (body mass index 30.1 ± 3.77) and except for one case (left ventricular-assist device) showed preserved ejection fraction (EF) (mean EF 57 ± 18.01). The retained devices were mostly located in the right coronary artery (50%), followed by the circumflex artery (37.5%) and diagonal branch (12.5%). The devices were remnants of guide wires (n = 4), balloon catheters (n = 3), and in one case a rotablator. Full sternotomy was performed in six patients and two received a left-sided minithoracotomy (n = 2). The operations were performed on-pump in five (62.5%) and off-pump in three patients. Complete extraction of the foreign bodies was possible in all patients. Two patients died; one in unrelated multiorgan failure and one due to retained-device-related right heart failure. The other patients survived and had uneventful postoperative courses. CONCLUSIONS Retained foreign bodies from cardiac interventions can be completely removed surgically using individualized approaches. There appears to be a trend toward a rising incidence of such interventional complications.

Abstract
BACKGROUND Currently, patient selection in TAVI is based upon a multidisciplinary heart team assessment of patient comorbidities and surgical risk stratification. In an era of increasing need for precision medicine and quickly expanding TAVI indications, machine learning has shown promise in making accurate predictions of clinical outcomes. This study aims to predict different intrahospital clinical outcomes in patients undergoing TAVI using a machine learning-based approach. The main clinical outcomes include all-cause mortality, stroke, major vascular complications, paravalvular leakage, and new pacemaker implantations. METHODS AND RESULTS The dataset consists of 451 consecutive patients undergoing elective TAVI between February 2014 and June 2016. The applied machine learning methods were neural networks, support vector machines, and random forests. Their performance was evaluated using five-fold nested cross-validation. Considering all 83 features, the performance of all machine learning models in predicting all-cause intrahospital mortality (AUC 0.94-0.97) was significantly higher than both the STS risk score (AUC 0.64), the STS/ACC TAVR score (AUC 0.65), and all machine learning models using baseline characteristics only (AUC 0.72-0.82). Using an extreme boosting gradient, baseline troponin T was found to be the most important feature among all input variables. Overall, after feature selection, there was a slightly inferior performance. Stroke, major vascular complications, paravalvular leakage, and new pacemaker implantations could not be accurately predicted. CONCLUSIONS Machine learning has the potential to improve patient selection and risk management of interventional cardiovascular procedures, as it is capable of making superior predictions compared to current logistic risk scores.

Abstract
Background Cardiac graft denervation causes inadequate sinus tachycardia in patients after heart transplantation (HTX) which is associated with reduced survival. This study investigated the 5-year results of heart rate control with ivabradine or metoprolol succinate in patients after HTX. Methods This registry study analyzed 104 patients receiving either ivabradine (n = 50) or metoprolol succinate (n = 54) within 5 years after HTX. Analysis included patient characteristics, medication, echocardiographic features, cardiac catheterization data, cardiac biomarkers, heart rates, and post-transplant survival including causes of death. Results Demographics and post-transplant medication revealed no significant differences except for ivabradine and metoprolol succinate use. At 5-year follow-up, patients with ivabradine had a significantly lower heart rate (73.3 bpm) compared to baseline (88.6 bpm; P < 0.01) and to metoprolol succinate (80.4 bpm; P < 0.01), a reduced left ventricular mass (154.8 g) compared to baseline (179.5 g; P < 0.01) and to metoprolol succinate (177.3 g; P < 0.01), a lower left ventricular end-diastolic pressure (LVEDP; 12.0 mmHg) compared to baseline (15.5 mmHg; P < 0.01) and to metoprolol succinate (17.1 mmHg; P < 0.01), and a reduced NT-proBNP level (525.4 pg/ml) compared to baseline (3826.3 pg/ml; P < 0.01) and to metoprolol succinate (1038.9 pg/ml; P < 0.01). Five-year post-transplant survival was significantly better in patients with ivabradine (90.0%) versus metoprolol succinate (68.5%; P < 0.01). Conclusion Patients receiving ivabradine showed a superior heart rate reduction and a better left ventricular diastolic function along with an improved 5-year survival after HTX.

Abstract
AIMS Percutaneous mitral annuloplasty (PMA) represents a new treatment option for secondary mitral regurgitation (SMR) being associated with higher morbidity and mortality. The present study was aimed to evaluate whether or not acute effects on SMR severity can quantitatively be assessed after PMA. METHODS AND RESULTS PMA was performed in 30 patients (mean age 76 ± 9; 37% males) with moderate (n = 14) or severe (n = 16) SMR. Vena contracta (VC), left ventricular (LV) velocity-time-integral ratio (VTIMV/LVOT ), effective regurgitant orifice area (EROA) by two-dimensional proximal isovelocity surface area (PISA), regurgitant volume (RVolPISA ) and regurgitant fraction (RFPISA ) by PISA, RVolvolume and RFvolume by LV volume analyses, and parameters describing LV morphology, function, and cardiac performance were assessed by transthoracic echocardiography prior to and after PMA. According to RFPISA /RFvolume , 14 patients showed mild, 15 moderate, and 1 severe SMR after PMA. Mean RF, RVol, EROA, VC, and VTIMV/LVOT were lower directly after PMA (RFPISA : 49% ± 11 vs. 34% ± 13, P < 0.001; RFvolume : 46% ± 10 vs. 34% ± 13, P < 0.001; RVolPISA : 33 mL ± 13 vs. 25 mL ± 12, P < 0.001; RVolvolume : 28 mL ± 17 vs. 20 mL ± 14, P < 0.05; EROAPISA : 0.24 cm2 ± 0.1 vs. 0.19 cm2 ± 0.1, P < 0.05; VC: 5.2 ± 0.1 vs. 4.1 ± 0.2, P < 0.001; VTIMV/LVOT : 1.9 ± 0.4 vs. 1.6 ± 0.5, P < 0.05). Parameters of LV morphology, function, and cardiac performance did not change directly after PMA. CONCLUSIONS PMA leads to a reduction of MR severity in >80% of SMR patients. Acute effects of PMA can quantitatively be assessed by transthoracic echocardiography.

Abstract
OBJECTIVES Functional mitral regurgitation (FMR) in patients with non-ischaemic dilative cardiomyopathy (DCM) is associated with heart failure and poor outcome. Aggressively undersized annuloplasty as an annular solution for a ventricular problem ameliorates heart failure but may be associated with recurrent FMR and does not improve survival. We sought to analyse if moderately undersized annuloplasty with repositioning of both papillary muscles can lead to improved valve stability and outcome in patients with DCM and FMR. METHODS In 66 patients with DCM-associated FMR (age 66 ± 12 years, ejection fraction 29 ± 6% and mean pulmonary artery pressure 35 ± 11 mmHg) and severe leaflet tethering (tenting height ≥10 mm) bilateral papillary muscle repositioning was added to moderately undersized ring annuloplasty (median size 30 mm). Concomitant surgery included tricuspid valve repair in 86% of patients and atrial ablation in 44%. RESULTS The early mortality rate was 9%. Overall 5-year freedom from all-cause death, left ventricular assist device implantation or heart transplant was 58% (95% confidence interval 45-71%). Six patients underwent reoperation (redo repair n = 4). Reverse remodelling was observed during follow-up in 66% of patients with decreasing left ventricular end-diastolic diameters (66 ± 5 to 61 ± 12 mm; P < 0.001) and left ventricular end-systolic diameters (56 ± 9 to 51 ± 14 mm; P = 0.001). Subgroup analyses (partial versus complete ring, preoperative left ventricular end-diastolic diameters <65 mm vs left ventricular end-diastolic diameter ≥65 mm) documented similar survival rates. A competing risks regression analysis identified cerebral vascular disease (P = 0.01), use of a partial ring (P = 0.03) and absence of tricuspid valve repair (P = 0.03) as independent predictors of death. CONCLUSIONS The combination of bilateral papillary muscle repositioning and moderately undersized ring annuloplasty leads to stable mid-term repair results and reverse remodelling in patients with DCM and FMR and severe leaflet tethering.

Abstract
BACKGROUND Cardiac amyloidosis, caused by deposition of immunoglobulin light chains (AL) or transthyretin (ATTR), carries a poor prognosis. Established risk scores for amyloidosis may not predict outcomes in those patients who develop advanced heart failure and who are potential candidates for heart transplantation. Here, we aimed to identify predictive parameters for patients with severe heart failure due to amyloidosis. METHODS Out of > 1000 patients with cardiac amyloidosis (AL or ATTR) admitted to our centre between September 1998 and January 2016, a cohort of 120 patients with a complete cardiac assessment at diagnosis, including right heart catheterization, echocardiography and biomarkers, was analysed retrospectively in this study. Primary endpoint was all-cause mortality. We performed univariate and multivariate Cox regression analysis, generated risk scores to predict outcomes in AL and ATTR amyloidosis and compared those to established risk models for amyloidosis. RESULTS In the Cox multivariate model, high-sensitivity troponin T (hsTnT; hazard ratio (HR) 1.003; confidence interval (CI) 1.001-1.005; p = 0.009) and mean pulmonary artery pressure (HR 1.061; CI 1.024-1.100; p = 0.001) were found to significantly and independently predict outcomes for AL amyloidosis, whereas QRS duration (HR 1.021; CI 1.004-1.039; p = 0.013), hsTnT (HR 1.021; CI 1.006-1.036; p = 0.006) and N-terminal pro-brain natriuretic peptide (HR 1.0003; CI 1.0001-1.0004; p = 0.002) were the best predictors for ATTR amyloidosis. A simple risk score ("HeiRisk") including these parameters for AL and ATTR allowed a more precise risk stratification in our patient population compared to established risk models. CONCLUSIONS Risk stratification for cardiac amyloidosis with the newly developed "HeiRisk" score may be superior to other staging systems for patients with advanced heart failure due to amyloid cardiomyopathy.

Abstract
According to recent recommendations on echocardiographic assessment of aortic valve stenosis direct measurement of transvalvular peak jet velocity, calculation of transvalvular mean gradient from the velocities using the Bernoulli equation and calculation of the effective aortic valve area by continuity equation are the appropriate primary key instruments for grading severity of aortic valve stenosis. It is obvious that no gold standard can be declared for grading the severity of aortic stenosis. Thus, conclusions of the exclusive evaluation of aortic stenosis by Doppler echocardiography seem to be questionable due to the susceptibility to errors caused by methodological limitations, mathematical simplifications and inappropriate documentation. The present paper will address practical issues of echocardiographic documentation to satisfy the needs to analyze different scenarios of aortic stenosis due to various flow conditions and pressure gradients. Transesophageal and multidimensional echocardiography should be implemented for reliable measurement of geometric aortic valve area and of cardiac dimensions at an early stage of the diagnostic procedure to avoid misinterpretation due to inconsistent results.

Abstract
Two recent trials of transcatheter mitral-valve repair in patients with functional mitral regurgitation (FMR) presented opposing results for the MitraClip® compared to medical therapy alone. The conflicting results gave rise to intensive discussions about assessment of mitral valve regurgitation (MR). A recent editorial viewpoint provided a potential explanation presenting a new pathophysiologic concept. However, the echocardiographic characterization of both trials' patients is inconsistent and the discussed concepts appear to suffer from plausibility weaknesses. It is well conceivable that limitations in the echocardiographic assessment of the trial patients introduced a bias regarding the selection of patients with severe (or less severe) MR that may be a more plausible explanation for the differences in outcome. We here illustrate our viewpoint regarding the two MitraClip trials and also illustrate the difficulties in assessing functional MR properly. It may indeed be "opening Pandora's box", but we will also make an attempt to provide a solution.

Abstract
BACKGROUND Transcatheter aortic valve implantation (TAVI) is emerging as the standard of care for patients with severe aortic stenosis. Recent results have been favourable even for patients with low periprocedural risk. METHODS We analysed the number of procedures, complications, and in-hospital mortality rates of all patients undergoing isolated aortic valve replacement in 2017 in Germany, focussing especially on transvascular (TV) TAVI. Patients were stratified according the German Aortic Valve Score (AKL) into the risk classes low, intermediate, high and very high (≥ 10%). RESULTS A total of 17,956 TV-TAVI and 9011 isolated surgical aortic valve replacements (iSAVR) were performed in Germany in 2017. Although the total rate of intraprocedural complications after TV-TAVI was the same as in 2016 (both 7.4%), fewer patients experienced an arterial vascular complication in 2017 (2017: 6.0%; 2016: 7.1%; p < 0.001). Likewise, the rate of new pacemaker implantation decreased (2017: 9.6%; 2016:11.4%; p < 0.001). In-hospital mortality after TV-TAVI and iSAVR was equal (2.7%) in 2017, despite the much higher risk profile of TV-TAVI patients. Using the AKL score as reference, TV-TAVI showed a more favourable observed-to-expected mortality (O/E) ratio (0.89) than iSAVR (1.14)- even more pronounced in patients at low risk (0.81 vs. 1.14). CONCLUSIONS The rates of major complications like bleeding and permanent pacemaker implantation after TV-TAVI keep declining. In 2017 patients undergoing TV-TAVI had a low in-hospital mortality rate with an O/E ratio < 1, indicating that the results were again better than those of all TAVI and SAVR of the previous year. Overall in-hospital mortality after transvascular TAVI and isolated aortic valve repair 2017 in Germany stratified to risk groups by the German Aortic Valve Score (German AV Score/AKL Score): low risk group (AKL 0- < 3%), intermediate risk group (AKL 3- < 6%), high risk group (AKL 6- < 10%) and very high risk group (AKL ≥ 10%).
