Abstract
The aim of this meta-analysis was to determine the effect of pulmonary hypertension (PH) on survival in patients undergoing transcatheter aortic valve replacement (TAVR). The present study was conducted according to the guidelines of Preferred Reporting of Systematic Review and Meta-Analysis (PRISMA). We conducted a comprehensive search of electronic databases including PubMed/MEDLINE, Embase, Cochrane Library, and Web of Science from January 1, 2015, to March 10, 2024. Outcomes assessed in this meta-analysis included early and late all-cause mortality and cardiovascular mortality. Total 15 studies were integrated into the pooled analysis to assess the impact of PH on outcomes among patients undergoing TAVR, comprising a total sample size of 35,732 individuals. The pooled prevalence of PH stood at 52.57% (n=18,767). Predominantly, the studies were conducted in the United States (n=6), followed by Germany (n=3), with one study each from Japan, Italy, Switzerland, Brazil, Poland, and Australia. Pooled analysis showed that risk of short-term mortality was greater in patients with PH compared to patients without PH (risk ratio (RR): 1.46, 95% CI: 1.19 to 1.80). Risk of long-term mortality was greater in patients with PH (RR: 1.42, 95% CI: 1.29 to 1.55). Risk of cardiovascular mortality was also greater in patients with PH compared to patients without PH (RR: 1.66, 95% CI: 1.36 to 2.02). We advocate for further research to address gaps in understanding different types of PH and their impacts on mortality and cardiovascular outcomes.

Abstract
Aims To evaluate the impact of neutrophil-to-lymphocyte ratio (NLR) on periprocedural pulmonary hypertension (PH) and 3-month all-cause mortality in patients with aortic stenosis (AS) who underwent transcatheter aortic valve replacement (TAVR) and to develop a nomogram for predicting the mortality for these patients. Methods and Results 124 patients undergoing TAVR were categorized into three groups according to systolic pulmonary artery pressure (sPAP): Group I (no PH, n = 61) consisted of patients with no pre- and post-TAVR PH; Group II (improved PH, n = 35) consisted of patients with post-TAVR systolic pulmonary artery pressure (sPAP) decreased by more than 10 mmHg compared to pre-TAVR levels; and Group III (persistent PH, n = 28) consisted of patients with post-TAVR sPAP no decrease or less than 10 mmHg, or new-onset PH after the TAVR procedure. The risk of all-cause mortality within 3 months tended to be higher in Group II (11.4%) and Group III (14.3%) compared to Group I (3.3%) (P=0.057). The multinomial logistic regression analysis demonstrated a positive correlation between NLR and both improved PH (OR: 1.182, 95% CI: 1.036-1.350, P=0.013) and persistent PH (OR: 1.181, 95% CI: 1.032-1.352, P=0.016). Kaplan-Meier analysis revealed a significant association between higher NLR and increased 3-month all-cause mortality (16.1% vs. 3.1% in lower NLR group, P=0.021). The multivariable Cox regression analysis confirmed that NLR was an independent predictor for all-cause mortality within 3 months, even after adjusting for clinical confounders. A nomogram incorporating five factors (BNP, heart rate, serum total bilirubin, NLR, and comorbidity with coronary heart disease) was developed. ROC analysis was performed to discriminate the ability of the nomogram, and the AUC was 0.926 (95% CI: 0.850-1.000, P < 0.001). Conclusions Patients with higher baseline NLR were found to be at an increased risk of periprocedural PH and all-cause mortality within 3 months after TAVR.

Abstract
Pulmonary hypertension (PH) is highly prevalent in patients with left heart disease (LHD) and negatively impacts prognosis. The most common causes of PH associated with LHD (PH-LHD) are left heart failure and valvular heart disease. In LHD, passive backward transmission of increased left-sided filling pressures leads to isolated post-capillary PH. Additional pulmonary vasoconstriction and remodelling lead to a higher vascular load and combined pre- and post-capillary PH. The increased afterload leads to right ventricular dysfunction and failure. Multimodality imaging of the heart plays a central role in the diagnostic work-up and follow-up of patients with PH-LHD. Echocardiography provides information about the estimated pulmonary artery pressure, morphology and function of the left and right side of the heart, and valvular abnormalities. Cardiac magnetic resonance imaging is the gold standard for volumetric measurements and provides myocardial tissue characterisation. Computed tomography of the thorax may show general features of PH and/or LHD and is helpful in excluding other PH causes. Histopathology reveals a spectrum of pre- and post-capillary vasculopathy, including intimal fibrosis, media smooth muscle cell hyperplasia, adventitial fibrosis and capillary congestion. In this paper, we provide an overview of clinical, imaging and histopathological findings in PH-LHD based on three clinical cases.

Abstract
Pulmonary hypertension (PH) is a common comorbidity in patients with aortic stenosis (AS) who are candidates for transcatheter aortic valve implantation (TAVI). Herein, we sought to elucidate the prognostic value of preprocedural PH on the early and late mortality after TAVI. The Cochrane Library, Scopus, PubMed, Web of Science, Embase, and ProQuest were screened using a predefined search query. We considered odds ratios (ORs) as the measure of effect. Meta-regression analysis was applied to investigate the potential impact of baseline characteristics on the outcomes. Egger's and Begg's tests were used to assess the publication bias. Thirty-three studies comprising 34 datasets representing 68,435 patients were included in the analysis. Regardless of the definition and severity of PH, pooled data analysis indicated that preprocedural PH was associated with higher cardiac and overall 30-day [OR, 1.45 (1.15-1.82) and OR, 1.75 (1.42-2.17), respectively], and 1-year mortality [OR, 1.63 (1.35-1.96) and OR, 1.59 (1.38-1.82), respectively]. Meta-regression analysis demonstrated that older age, higher New York Heart Association function class, history of hypertension, diabetes, and lower left ventricular ejection fraction were predictors of higher mortality rate following TAVI. Moreover, we found that preprocedural PH is significantly associated with higher in-hospital mortality and 30-day acute kidney injury. Our results demonstrated that preprocedural PH is associated with higher early and late cardiac and overall mortality following TAVI; however, this finding is limited regarding the considerable inconsistency in the definition of PH and PH severity among studies.

Abstract
BACKGROUND While pulmonary hypertension (PH) in patients with severe aortic valve stenosis (AS) is associated with increased mortality after transcatheter aortic valve replacement (TAVR), there is limited data on gender differences in the effects on long-term survival. OBJECTIVE The aim of this retrospective, multicenter study was to investigate the prognostic impact of pre-interventional PH on survival of TAVR patients with respect to gender. METHODS 303 patients undergoing TAVR underwent echocardiography to detect PH prior to TAVR via measurement of systolic pulmonary artery pressure (sPAP). Different cut-off values were set for the presence of PH. The primary endpoint was all-cause mortality at 1, 3 and 5 years. RESULTS Kaplan-Meier analysis by gender showed that only males exhibited significant increased mortality at elevated sPAP values during the entire follow-up period of 5 years (sPAP ≥ 40 mmHg: p ≤ 0.001 and sPAP ≥ 50 mmHg: p ≤ 0.001 in 1- to 5-year survival), whereas high sPAP values had no effect on survival in females. In Cox regression analysis based on the selected sPAP thresholds, male gender was an independent risk factor for long-term mortality after TAVR in all time courses. CONCLUSION Male gender was an isolated risk factor for premature death after TAVR in patients with echocardiographic evidence of PH and severe AS. This could mean that, the indication for TAVR should be discussed more critically in men with severe AS and an elevated sPAP, while in females, PH should not be an exclusion criterion for TAVR.

Abstract
OBJECTIVE The European Society of Cardiology guidelines have recently defined new cut-offs for pulmonary hypertension (PH) and pulmonary vasculature resistance (PVR; median pulmonary artery pressure (mPAP) >20 instead of 25 mm Hg and PVR >2 instead of 3 Wood unit). The prognostic value of this updated classification after transcatheter aortic valve implantation (TAVI) is unknown. METHODS 579 consecutive patients treated by TAVI with preprocedural right heart catheterisation evaluation were included. Patients were grouped as: (1) no PH, (2) isolated precapillary/combined (I-PreC/Co) PH and (3) isolated postcapillary PH (I-PoC). All-cause death, cardiovascular death and hospitalisations for heart failure (HF) were evaluated at follow-up. We also analysed the prognostic role of residual postprocedural PH. RESULTS Out of 579 patients, 299 (52%) had PH according to the new criteria compared with 185 (32%) according to the previous ones. Overall median age was 82 years, while 55.3% patients were male. Patients with PH were more frequently diagnosed with chronic obstructive pulmonary disease and atrial fibrillation and were characterised by higher surgical risk as compared with patients without PH.At a median follow-up of 2.9 years, the presence of PH according to previous definition was associated with worse survival (p<0.001) and HF hospitalisation (p=0.002) rates, irrespective of PVR values. With newer cut-offs, PH was associated with worse outcomes only in patients with increased PVR, while no differences were found between patients with PH and normal PVR values and those without PH. Postprocedural mPAP normalisation was observed in 45% of the cases, but it was associated with improved long-term survival only in the I-PoC PH group. CONCLUSIONS New ESC PH cut-offs increased the number of PH diagnoses. The presence of PH, particularly in the setting of increased PVR, identify patients at higher risk for postprocedural mortality and rehospitalisation. Normalisation of PH was associated with better survival only in I-PoC group.

Abstract
BACKGROUND Transthoracic echocardiography (TTE) offers a measurement method for the determination of pulmonary hypertension (PH) in patients with severe aortic valve stenosis (AS) with determination of maximal tricuspid regurgitation velocity (TRVmax) and systolic pulmonary artery pressure (sPAP). Radiological parameters for noninvasive detection of PH, most importantly computed tomography (CT) based PA/AA-ratio = ratio of pulmonary artery diameter (PA) and ascending aorta diameter (AA), are also included in the latest ESC guidelines. The aim of the present study was to define cut-off values for PA/AA-ratio taking also into account cardiovascular biomarkers to determine criteria for noninvasive diagnosis of PH. METHODS 194 patients with severe AS undergoing transcatheter aortic valve replacement (TAVR) underwent pre-procedural TTE and CT with measurement of PA/AA-ratio. Additionally, common cardiovascular biomarkers were determined. RESULTS TAVR patients with an sPAP ≥ 40 mmHg or a TRVmax ≥ 2.9 m/s had a PA/AA-ratio ≥ 0.80 in an AUROC analysis. The cut-off value of ≥ 0.80 resulted in a significantly higher mortality rate (log-rank test: p = 0.034) in these patients in a Kaplan-Meier analysis regarding 1-year survival after TAVR. Significant differences in biomarker expression between patients with a PA/AA-ratio ≥ 0.80 or < 0.80 occurred for BNP (p = 0.001), cTnI (p = 0.032), GDF-15 (p = 0.002) and H-FABP (p = 0.015). CONCLUSION PA/AA-ratio ≥ 0.80 is a promising radiological parameter that can provide information about mortality in patients with severe AS undergoing TAVR; combined with biomarkers it may contribute to noninvasive detection of PH in patients with severe AS.

Abstract
BACKGROUND There is limited evidence regarding the association between right ventricular-to-pulmonary artery (RV-PA) coupling and outcomes after transcatheter aortic valve replacement (TAVR). OBJECTIVES This study aimed to explore the evolution of RV-PA coupling in patients with severe aortic stenosis undergoing TAVR and its prognostic impact. METHODS A total of 900 patients who underwent TAVR in 2 tertiary centers and with echocardiographic analysis performed within 3 months before and after the procedure were included. RV-PA coupling was measured as the ratio of tricuspid annular plane systolic excursion (TAPSE) to pulmonary artery systolic pressure (PASP). RV-PA uncoupling was defined by TAPSE/PASP <0.55, whereas a TAPSE/PASP <0.32 identified a severe uncoupling. The primary endpoint was all-cause mortality. RESULTS A total of 520 patients (58%) showed RV-PA uncoupling before TAVR, whereas post-TAVR RV-PA uncoupling was observed in 407 patients (45%). During a median follow-up of 40 months, 250 deaths (28%) occurred. Post-TAVR RV-PA uncoupling was independently associated with an increased risk of mortality (adjusted HR: 1.474; 95% CI: 1.115-1.948; P = 0.006), whereas pre-TAVR uncoupling did not. Among patients with post-TAVR RV-PA uncoupling, the presence of severe uncoupling identified a subgroup with the worst survival (P = 0.008). Patients with RV-PA coupling recovery after TAVR showed similar outcomes as compared with patients with normal coupling. Conversely, the presence of either persistent or new-onset RV-PA uncoupling following TAVR was associated with an increased mortality risk. CONCLUSIONS Post-TAVR RV-PA uncoupling is an independent predictor of long-term mortality, irrespective of coupling before intervention. Assessment of TAPSE/PASP response after TAVR may be helpful to improve risk stratification.

Right ventricle to pulmonary artery coupling after transcatheter aortic valve implantation-Determinant factors and prognostic impact. Front Cardiovasc Med 2023; 10:1150039. [PMID: 37139141 PMCID: PMC10150002 DOI: 10.3389/fcvm.2023.1150039] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Accepted: 03/27/2023] [Indexed: 05/05/2023] Open
Abstract
Introduction Right ventricular (RV) dysfunction and pulmonary hypertension (PH) have been previously associated with unfavorable outcomes in patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI), but little is known about the effect of right ventricle (RV) to pulmonary artery (PA) coupling. Our study aimed to evaluate the determinant factors and the prognostic value of RV-PA coupling in patients undergoing TAVI. Methods One hundred sixty consecutive patients with severe AS were prospectively enrolled, between September 2018 and May 2020. They underwent a comprehensive echocardiogram before and 30 days after TAVI, including speckle tracking echocardiography (STE) for myocardial deformation analysis of the left ventricle (LV), left atrium (LA), and RV function. Complete data on myocardial deformation was available in 132 patients (76.6 ± 7.5 years, 52.5% men) who formed the final study population. The ratio of RV free wall longitudinal strain (RV-FWLS) to PA systolic pressure (PASP) was used as an estimate of RV-PA coupling. Patients were analyzed according to baseline RV-FWLS/PASP cut-off point, determined through time-dependent ROC curve analysis, as follows: normal RV-PA coupling group (RV-FWLS/PASP ≥0.63, n = 65) and impaired RV-PA coupling group (RV-FWLS/PASP < 0.63, n = 67). Results A significant improvement of RV-PA coupling was observed early after TAVI (0.75 ± 0.3 vs. 0.64 ± 0.3 before TAVI, p < 0.001), mainly due to PASP decrease (p < 0.001). LA global longitudinal strain (LA-GLS) is an independent predictor of RV-PA coupling impairment before and after TAVI (OR = 0.837, p < 0.001, OR = 0.848, p < 0.001, respectively), while RV diameter is an independent predictor of persistent RV-PA coupling impairment after TAVI (OR = 1.174, p = 0.002). Impaired RV-PA coupling was associated with a worse survival rate (66.3% vs. 94.9%, p-value < 0.001) and emerged as an independent predictor of mortality (HR = 5.97, CI = 1.44-24.8, p = 0.014) and of the composite endpoint of death and rehospitalization (HR = 4.14, CI = 1.37-12.5, p = 0.012). Conclusion Our results confirm that relief of aortic valve obstruction has beneficial effects on the baseline RV-PA coupling, and they occur early after TAVI. Despite significant improvement in LV, LA, and RV function after TAVI, RV-PA coupling remains impaired in some patients, it is mainly related to persistent pulmonary hypertension and is associated with adverse outcomes.

Outcomes of Preprocedural Pulmonary Hypertension on All-Cause and Cardiac Mortality in Patients Undergoing Transcatheter Aortic Valve Implantation: A Systematic Review. Cureus 2023; 15:e34300. [PMID: 36860229 PMCID: PMC9969809 DOI: 10.7759/cureus.34300] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2022] [Accepted: 01/27/2023] [Indexed: 01/30/2023] Open
Abstract
Patients with symptomatic aortic stenosis (AS) commonly have an associated finding of pulmonary hypertension (PH), and it has been previously shown to have increased morbidity and mortality following surgical aortic valve repair (SAVR) as well as transcatheter aortic valve implantation (TAVI). There are no guidelines stating the cut-off point for PH at which the patient can safely undergo TAVI with benefits outweighing the risks. This is partly due to the lack of uniformity in the PH definition used in various studies. This systematic review sought to study the effect of preprocedural pulmonary hypertension on early and late all-cause and cardiac mortality in patients undergoing TAVI. We performed a systematic review of studies comparing patients with AS undergoing TAVI having PH. The review was undertaken as per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Articles were identified from PubMed, Pubmed Central (PMC), Cochrane, and Medline on January 10, 2022, for literature published until January 10, 2022. MeSH strategy was used on PubMed to search the literature, and filters were applied to search only Observational Studies, randomized controlled trials (RCT), and meta-analysis. A total of 170 unique articles were identified and screened. Of the 33 full-text articles that were reviewed, 18 articles, including duplicates, were excluded. Fifteen articles fulfilled the selection criteria and were included in this review. The study design included two meta-analyses, one randomized control trial, one prospective cohort study, and 11 retrospective cohort studies. The studies involved a total of approximately 30,000 patients. The observational studies in our review were of good to fair quality, the RCT had a low to moderate bias, and the meta-analysis was of moderate quality. Baseline PH and persistence of PH post-TAVI are strongly associated with all-cause and cardiac mortality. Few studies have shown that a decrease in post-TAVI PH carries mortality benefits. Therefore, efforts should be made to identify mechanisms of persistent PH post-TAVI and whether interventions to reduce PH pre-TAVI will have any clinical implications or not by conducting RCT.

Abstract
OBJECTIVE A novel artificial intelligence-based phenotyping approach to stratify patients with severe aortic stenosis (AS) prior to transcatheter aortic valve replacement (TAVR) has been proposed, based on echocardiographic and haemodynamic data. This study aimed to analyse the recovery of extra-aortic valve cardiac damage in accordance with this novel stratification system following TAVR. METHODS The proposed phenotyping approach was previously established employing data from 366 patients with severe AS from a bicentric registry. For this consecutive study, echocardiographic follow-up data, obtained on day 147±75.1 after TAVR, were available from 247 patients (67.5%). RESULTS Correction of severe AS by TAVR significantly reduced the proportion of patients suffering from concurrent severe mitral regurgitation (from 9.29% to 3.64%, p value: 0.0015). Moreover, pulmonary artery pressures were ameliorated (estimated systolic pulmonary artery pressure: from 47.2±15.8 to 43.3±15.1 mm Hg, p value: 0.0079). However, right heart dysfunction as well as the proportion of patients with severe tricuspid regurgitation remained unchanged. Clusters with persistent right heart dysfunction ultimately displayed 2-year survival rates of 69.2% (95% CI 56.6% to 84.7%) and 74.6% (95% CI 65.9% to 84.4%), which were significantly lower compared with clusters with little or no persistent cardiopulmonary impairment (88.3% (95% CI 83.3% to 93.5%) and 85.5% (95% CI 77.1% to 94.8%)). CONCLUSIONS This phenotyping approach preprocedurally identifies patients with severe AS, who will not recover from extra-aortic valve cardiac damage following TAVR and whose survival is therefore significantly reduced. Importantly, not the degree of pulmonary hypertension at initial presentation, but the irreversibility of right heart dysfunction determines prognosis.

Comparability between Computed Tomography Morphological Vascular Parameters and Echocardiography for the Assessment of Pulmonary Hypertension in Patients with Severe Aortic Valve Stenosis-Results of a Multi-Center Study. Diagnostics (Basel) 2022; 12:2363. [PMID: 36292052 PMCID: PMC9600691 DOI: 10.3390/diagnostics12102363] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Revised: 09/23/2022] [Accepted: 09/26/2022] [Indexed: 12/03/2022] Open
Abstract
Background: Computed tomography (CT) of the aorta and cardiac vessels, which is performed in patients with severe aortic valve stenosis (AS) before transcatheter aortic valve replacement (TAVR), offers the possibility of non-invasive detection of pulmonary hypertension (PH), for example, by determining the diameter of the main pulmonary artery (PA), the right pulmonary artery (RPA) or the left pulmonary artery (LPA). An improvement of the significance of these radiological parameters is often achieved by indexing to the body surface area (BSA). The aim of this study was to compare different echocardiographic systolic pulmonary artery pressure (sPAP) values with radiological data in order to define potential clinical cut-off values for the presence or absence of PH. Methods: A total of 138 patients with severe AS undergoing TAVR underwent pre-interventional transthoracic echocardiography with determination of sPAP values and performance of CT angiography (CTA) of the aorta and femoral arteries. Radiologically, the PA, RPA, LPA, and ascending aorta (AA) diameters were obtained. Vascular diameters were not only indexed to BSA but also ratios were created with AA diameter (for example PA/AA-ratio). From these CT-derived vascular parameters, AUROC curves were obtained regarding the prediction of different sPAP values (sPAP 40−45−50 mmHg) and finally correlation analyses were calculated. Results: The best AUROC and correlation analyses were generally obtained at an sPAP ≥ 40 mmHg. When considering diameters alone, the PA diameter was superior to the RPA and LPA. Indexing to BSA generally increased the diagnostic quality of the parameters, and finally, in a synopsis of all results, PA/BSA had the best AUC 0.741 (95% CI 0.646−0. 836; p < 0.001; YI 0.39; sensitivity 0.87; specificity 0.52) and Spearman’s correlation coefficient (r = 0.408; p < 0.001) at an sPAP of ≥40 mmHg. Conclusions: Features related to pulmonary hypertension are fast and easily measurable on pre-TAVR CT and offer great potential regarding non-invasive detection of pulmonary hypertension in patients with severe AS and can support the echocardiographic diagnosis. In this study, the diameter of the main pulmonary artery with the additionally determined ratios were superior to the values of the right and left pulmonary artery. Additional indexing to body surface area and thus further individualization of the parameters with respect to height and weight can further improve the diagnostic quality.

The Evolution of Pulmonary Hypertension and Its Prognostic Implications Post-TAVI-Single Center Experience. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58091182.

Abstract
Background and Objectives: Since the first transcatheter aortic valve implantation (TAVI) procedure was performed in 2002, advances in technology and refinement of the method have led to its widespread use in patients with severe aortic stenosis (AS) and high surgical risk. We aim to identify the impact of TAVI on the clinical and functional status of patients with severe AS at the one-month follow-up and to identify potential predictors associated with the evolution of pulmonary hypertension (PH) in this category of patients. Materials and Methods: We conducted a prospective study which included 86 patients diagnosed with severe AS undergoing TAVI treatment. We analyzed demographics, clinical and echocardiographic parameters associated with AS and PH both at enrolment and at the 30-day follow-up. Results: In our study, the decrease of EUROSCORE II score (p < 0.001), improvement of angina (p < 0.001) and fatigue (p < 0.001) as clinical benefits as well as a reduction in NYHA functional class in patients with heart failure (p < 0.001) are prognostic predictors with statistical value. Regression of left ventricular hypertrophy (p = 0.001), increase in the left ventricle ejection fraction (p = 0.007) and improvement of diastolic dysfunction (p < 0.001) are echocardiographic parameters with a prognostic role in patients with severe AS undergoing TAVI. The pulmonary artery acceleration time (PAAT) (p < 0.001), tricuspid annular plane systolic excursion (TAPSE) (p = 0.020), pulmonary arterial systolic pressure (PASP) (p < 0.001) and the TAPSE/PASP ratio (p < 0.001) are statistically significant echocardiographic parameters in our study that assess both PH and its associated prognosis in patients undergoing TAVI. Conclusions: PAAT, TAPSE, PASP and the TAPSE/PASP ratio are independent predictors that allow the assessment of PH and its prognostic implications post-TAVI.

Abstract
Aims Hypothesizing that aortic outflow velocity profiles contain more valuable information about aortic valve obstruction and left ventricular contractility than can be captured by the human eye, features of the complex geometry of Doppler tracings from patients with severe aortic stenosis (AS) were extracted by a convolutional neural network (CNN). Methods and results After pre-training a CNN (VGG-16) on a large data set (ImageNet data set; 14 million images belonging to 1000 classes), the convolutional part was employed to transform Doppler tracings to 1D arrays. Among 366 eligible patients [age: 79.8 ± 6.77 years; 146 (39.9%) women] with pre-procedural echocardiography and right heart catheterization prior to transcatheter aortic valve replacement (TAVR), good quality Doppler tracings from 101 patients were analysed. The convolutional part of the pre-trained VGG-16 model in conjunction with principal component analysis and k-means clustering distinguished two shapes of aortic outflow velocity profiles. Kaplan-Meier analysis revealed that mortality in patients from Cluster 2 (n = 40, 39.6%) was significantly increased [hazard ratio (HR) for 2-year mortality: 3; 95% confidence interval (CI): 1-8.9]. Apart from reduced cardiac output and mean aortic valve gradient, patients from Cluster 2 were also characterized by signs of pulmonary hypertension, impaired right ventricular function, and right atrial enlargement. After training an extreme gradient boosting algorithm on these 101 patients, validation on the remaining 265 patients confirmed that patients assigned to Cluster 2 show increased mortality (HR for 2-year mortality: 2.6; 95% CI: 1.4-5.1, P-value: 0.004). Conclusion Transfer learning enables sophisticated pattern recognition even in clinical data sets of limited size. Importantly, it is the left ventricular compensation capacity in the face of increased afterload, and not so much the actual obstruction of the aortic valve, that determines fate after TAVR.

Severe Aortic Valve Stenosis and Pulmonary Hypertension: A Systematic Review of Non-Invasive Ways of Risk Stratification, Especially in Patients Undergoing Transcatheter Aortic Valve Replacement. J Pers Med 2022; 12:jpm12040603.

Abstract
Patients with severe aortic valve stenosis and concomitant pulmonary hypertension show a significantly reduced survival prognosis. Right heart catheterization as a preoperative diagnostic tool to determine pulmonary hypertension has been largely abandoned in recent years in favor of echocardiographic criteria. Clinically, determination of echocardiographically estimated systolic pulmonary artery pressure falls far short of invasive right heart catheterization data in terms of accuracy. The aim of the present systematic review was to highlight noninvasive possibilities for the detection of pulmonary hypertension in patients with severe aortic valve stenosis, with a special focus on cardiovascular biomarkers. A total of 525 publications regarding echocardiography, cardiovascular imaging and biomarkers related to severe aortic valve stenosis and pulmonary hypertension were analyzed in a systematic database analysis using PubMed Central®. Finally, 39 publications were included in the following review. It was shown that the current scientific data situation, especially regarding cardiovascular biomarkers as non-invasive diagnostic tools for the determination of pulmonary hypertension in severe aortic valve stenosis patients, is poor. Thus, there is a great scientific potential to combine different biomarkers (biomarker scores) in a non-invasive way to determine the presence or absence of PH.

Abstract
OBJECTIVES This study aimed to improve echocardiographic assessment of pulmonary hypertension (PH) in patients presenting with severe tricuspid regurgitation (TR). BACKGROUND Echocardiographic assessment of PH in patients with severe TR carries several pitfalls for underestimation, hence concealing the true severity of PH in very sick patients in particular, and ultimately obscuring the impact of PH on survival after transcatheter tricuspid valve intervention (TTVI). METHODS All patients in this study underwent TTVI for severe TR between 2016 and 2020. To predict the mean pulmonary artery pressure (mPAP) solely based on echocardiographic parameters, we trained an extreme gradient boosting (XGB) algorithm. The derivation cohort was constituted by 116 out of 162 patients with both echocardiography and right heart catheterization data, preprocedurally obtained, from a bicentric registry. Moreover, 142 patients from an independent institution served for external validation. RESULTS Systolic pulmonary artery pressure was consistently underestimated by echocardiography in comparison to right heart catheterization (40.3 ± 15.9 mm Hg vs 44.1 ± 12.9 mm Hg; P = 0.0066), and the assessment was most discrepant among patients with severe defects of the tricuspid valve and impaired right ventricular systolic function. Using 9 echocardiographic parameters as input variables, an XGB algorithm could reliably predict mPAP levels (R = 0.96, P < 2.2 × 10-16). Moreover, patients with elevations in predicted mPAP levels ≥29.9 mm Hg showed significantly reduced 2-year survival after TTVI (58.3% [95% CI: 41.7%-81.6%] vs 78.8% [95% CI: 68.7%-90.5%]; P = 0.026). Importantly, the poor prognosis associated with elevation in predicted mPAP levels was externally confirmed (HR for 2-year mortality: 2.9 [95% CI: 1.5-5.7]; P = 0.002). CONCLUSIONS PH in patients with severe TR can be reliably assessed based on echocardiographic parameters in conjunction with an XGB algorithm, and elevations in predicted mPAP levels translate into increased mortality after TTVI.

Abstract
Although transcatheter aortic valve implantation (TAVI) has revolutionised the landscape of treatment for aortic stenosis, there exists a cohort of patients where TAVI is deemed futile. Among the pivotal high-risk trials, one-third to half of patients either died or received no symptomatic benefit from the procedure at 1 year. Futility of TAVI results in the unnecessary exposure of risk for patients and inefficient resource utilisation for healthcare services. Several cardiac and extra-cardiac conditions and frailty increase the risk of mortality despite TAVI. Among the survivors, these comorbidities can inhibit improvements in symptoms and quality of life. However, certain conditions are reversible with TAVI (e.g. functional mitral regurgitation), attenuating the risk and improving outcomes. Quantification of disease severity, identification of reversible factors and a systematic evaluation of frailty can substantially improve risk stratification and outcomes. This review examines the contribution of pre-existing comorbidities towards futility in TAVI and suggests a systematic approach to guide patient evaluation.

Baseline PA/BSA ratio in patients undergoing transcatheter aortic valve replacement - A novel CT-based marker for the prediction of pulmonary hypertension and outcome. Int J Cardiol 2021; 348:26-32. [PMID: 34923001 DOI: 10.1016/j.ijcard.2021.12.019] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2021] [Revised: 11/16/2021] [Accepted: 12/13/2021] [Indexed: 01/08/2023]
Abstract
BACKGROUND Pulmonary hypertension (pH) has a prognostic impact on patients undergoing transcatheter aortic valve replacement (TAVR). Pulmonary artery (PA) dilatation assessed by multidetector computed tomography (MDCT) has the potential to predict PH. The aim of the study was to evaluate the clinical parameters associated with PA dilatation and to investigate its prognostic relevance in patients undergoing TAVR. METHODS In 770 patients undergoing TAVR between February 2016 and July 2019, PA diameter was measured by MDCT before TAVR. Additionally, PA diameter divided by ascending aorta diameter or body surface area (BSA) was calculated. RESULTS Of all the CT-derived parameters compared with a receiver operating characteristic curve, the value for PA/BSA with a median of 1.68 (IQR 1.47, 1.91) cm/m2 showed the greatest area-under-the-curve (0.75) for predicting PH at baseline. Based on this median, patients were assigned to a small PA/BSA (n = 386) or a large PA/BSA (n = 384) group. Hereby, a large PA/BSA was independently associated with PH at baseline (OR:8.39 [5.36-13.14], p < 0.001) and after TAVR (OR:1.73 [1.18-2.53], p = 0.005). A large PA/BSA was associated with a significantly higher cumulative two-year all-cause mortality compared to small PA/BSA (30.0% vs. 13.7%, p < 0.001), which was supported in the multivariable model (HR:1.87; 95%CI, 1.12-3.04; p = 0.017). CONCLUSION Patients with a large PA/BSA on MDCT are more likely to have PH at baseline and after TAVR. Large PA/BSA is associated with an increased risk of mortality and could provide additional information for risk stratification in patients undergoing TAVR.

Impact of Pulmonary Artery Dilatation on Clinical Outcomes in Patients Undergoing Transcatheter Aortic Valve Replacement. JACC Cardiovasc Interv 2021; 14:2560-2569. [PMID: 34774478 DOI: 10.1016/j.jcin.2021.08.023] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Revised: 08/04/2021] [Accepted: 08/10/2021] [Indexed: 12/20/2022]
Abstract
OBJECTIVES The aim of this study was to evaluate the clinical impact of computed tomography (CT)-derived pulmonary artery dilatation (PAD) in patients undergoing transcatheter aortic valve replacement (TAVR). BACKGROUND Several studies have reported an association between pulmonary hypertension and cardiovascular events, but the prognostic value of PAD in patients undergoing TAVR remains unclear. METHODS The preprocedural computed tomographic studies of patients who underwent TAVR at Cedars-Sinai Medical Center between November 2013 and December 2017 were analyzed. Patients were divided into 2 groups according to the presence of PAD assessed on CT (pulmonary artery [PA] diameter ≥29 mm). The primary endpoint was all-cause mortality at 2 years. RESULTS A total of 895 patients were included (mean age 81.3 ± 8.5 years), with a mean Society of Thoracic Surgeons score of 4.8%. The median PA diameter was 28.0 mm, and PAD was observed in 369 patients (41.2%). Compared with the no-PAD group, the PAD group had higher Society of Thoracic Surgeons scores and higher rates of atrial fibrillation, chronic kidney disease, and chronic obstructive pulmonary disease. The PAD group had higher 2-year all-cause mortality than the no-PAD group (28.9% vs 12.8%; P < 0.001), and PAD was independently associated with mortality (adjusted HR: 2.21; 95% CI: 1.44-3.39; P < 0.001). Furthermore, PAD had strong prognostic power in the subgroup analysis, stratified according to PA pressure (>36 mm Hg). CONCLUSIONS CT-derived PAD is a significant prognostic factor in patients undergoing TAVR.

Abstract
OBJECTIVES The aim of this retrospective analysis was to categorize patients with severe aortic stenosis (AS) according to clinical presentation by applying unsupervised machine learning. BACKGROUND Patients with severe AS present with heterogeneous clinical phenotypes, depending on disease progression and comorbidities. METHODS Unsupervised agglomerative clustering was applied to preprocedural data from echocardiography and right heart catheterization from 366 consecutively enrolled patients undergoing transcatheter aortic valve replacement for severe AS. RESULTS Cluster analysis revealed 4 distinct phenotypes. Patients in cluster 1 (n = 164 [44.8%]), serving as a reference, presented with regular cardiac function and without pulmonary hypertension (PH). Accordingly, estimated 2-year survival was 90.6% (95% CI: 85.8%-95.6%). Clusters 2 (n = 66 [18.0%]) and 4 (n = 91 [24.9%]) both comprised patients with postcapillary PH. Yet patients in cluster 2 with preserved left and right ventricular structure and function showed a similar survival as those in cluster 1 (2-year survival 85.8%; 95% CI: 76.9%-95.6%), whereas patients in cluster 4 with dilatation of all heart chambers and a high prevalence of mitral and tricuspid regurgitation (12.5% and 14.8%, respectively) died more often (2-year survival 74.9% [95% CI: 65.9%-85.2%]; HR for 2-year mortality: 2.8 [95% CI: 1.4-5.5]). Patients in cluster 3, the smallest (n = 45 [12.3%]), displayed the most extensive disease characteristics (ie, left and right heart dysfunction together with combined pre- and postcapillary PH), and 2-year survival was accordingly reduced (77.3% [95% CI: 65.2%-91.6%]; HR for 2-year mortality: 2.6 [95% CI: 1.1-6.2]). CONCLUSIONS Unsupervised machine learning aids in capturing complex clinical presentations as observed in patients with severe AS. Importantly, structural alterations in left and right heart morphology, possibly due to genetic predisposition, constitute an equally sensitive indicator of poor prognosis compared with high-grade PH.

Abstract
(1) Background: Pulmonary hypertension after aortic valve replacement (AVR; post-AVR PH) carries a poor prognosis. We assessed the pre-AVR hemodynamic characteristics of patients with versus without post-AVR PH. (2) Methods: We studied 205 patients (mean age 75 ± 10 years) with severe AS (indexed aortic valve area 0.42 ± 0.12 cm2/m2, left ventricular ejection fraction 58 ± 11%) undergoing right heart catheterization (RHC) prior to surgical (70%) or transcatheter (30%) AVR. Echocardiography to assess post-AVR PH, defined as estimated systolic pulmonary artery pressure > 45 mmHg, was performed after a median follow-up of 15 months. (3) Results: There were 83/205 (40%) patients with pre-AVR PH (defined as mean pulmonary artery pressure (mPAP) ≥ 25 mmHg by RHC), and 24/205 patients (12%) had post-AVR PH (by echocardiography). Among the patients with post-AVR PH, 21/24 (88%) had already had pre-AVR PH. Despite similar indexed aortic valve area, patients with post-AVR PH had higher mPAP, mean pulmonary artery wedge pressure (mPAWP) and pulmonary vascular resistance (PVR), and lower pulmonary artery capacitance (PAC) than patients without. (4) Conclusions: Patients presenting with PH roughly one year post-AVR already had worse hemodynamic profiles in the pre-AVR RHC compared to those without, being characterized by higher mPAP, mPAWP, and PVR, and lower PAC despite similar AS severity.

Abstract
Aortic stenosis is the most common valvular disease requiring valve replacement. Valve replacement therapies have undergone progressive evolution since the 1960s. Over the last 20 years, transcatheter aortic valve replacement has radically transformed the care of aortic stenosis, such that it is now the treatment of choice for many, particularly elderly, patients. This review provides an overview of the pathophysiology, presentation, diagnosis, indications for intervention, and current therapeutic options for aortic stenosis.

Abstract
This thematic review focuses on recently proposed classification of stages in pronounced aortic stenosis based on the prevalence of extravalvular cardiac damage and its modified variant designed for asymptomatic patients. The review presents studies, which analyzed the predictive significance of the proposed classification. The use of this classification allows predicting the course of disease in patients with pronounced aortic stenosis in valve replacement. The classification is based on routinely used structural and functional echocardiographic signs with already proven predictive values with respect of adverse events in patients after aortic valve replacement. The review discusses limitations of the classification for pronounced aortic stenosis stages based on the prevalence of extravalvular cardiac damage.

Abstract
Background Preoperative pulmonary hypertension (PH) is associated with excess mortality among patients with severe mitral regurgitation undergoing mitral valve surgery (MVS). However, the links between PH phenotype, pulmonary vascular remodeling, and persistent postoperative PH are not well understood. We aimed to describe the associations between components of pulmonary hemodynamics as well as postoperative residual PH with longitudinal mortality in patients with severe mitral regurgitation who received MVS. Methods and Results Patients undergoing MVS for severe mitral regurgitation from 2011 to 2016 were retrospectively identified within our health system (n=488). Mean pulmonary artery pressure and other hemodynamic variables were determined by presurgical right-heart catheterization. Postoperative pulmonary artery systolic pressure was assessed on echocardiogram 42 to 365 days post-MVS. Longitudinal survival over a mean 3.9 years of follow-up was evaluated using Cox proportional hazards modeling to compare survival after adjustment for demographics, surgical characteristics, and comorbidities. Pre-MVS prevalence of PH was high at 85%. After adjustment, each 10-mm Hg increase in preoperative mean pulmonary artery pressure was associated with a 1.38-fold increase in risk of death (95% CI, 1.13-1.68). Elevated preoperative pulmonary vascular resistance, transpulmonary gradient, and right atrial pressure were similarly associated with increased mortality. Among 231 patients with postoperative echocardiogram, evidence of PH on echocardiogram (pulmonary artery systolic pressure ≥35 mm Hg) was associated with increased risk of death (hazard ratio [HR], 2.02 [95% CI, 1.17-3.47]); however, this was no longer statistically significant after adjustment (HR, 1.55 [95% CI, 0.85-2.85]). Conclusions In patients undergoing MVS for mitral regurgitation, preoperative PH, and postoperative PH were associated with increased mortality.

Abstract
Pulmonary hypertension (PH) due to left heart disease (LHD) is a frequent complication of heart failure (HF) and is associated with exercise intolerance, poor quality of life, increased risk of hospitalisations, and reduced overall survival. Since the recent Sixth World Symposium on Pulmonary Hypertension in 2018, there have been significant changes in the hemodynamic definitions and clinical classification of PH-LHD. PH-LHD can be subdivided into (1) isolated postcapillary PH (IpcPH) and (2) combined precapillary and postcapillary PH (CpcPH). This categorisation of PH-LHD is important because CpcPH shares certain pathophysiologic, clinical, and hemodynamic characteristics with pulmonary arterial hypertension and is associated with worse outcomes compared with IpcPH. A systematic approach using clinical history and noninvasive investigations is required in the diagnosis of PH-LHD. Right heart catheterisation with and without provocative testing is performed in expert centres and is indicated in selected individuals. Although the definition of IpcPH and CpcPH is based on measurements made with right heart catheterisation, distinguishing between these two entities is not always necessary. Despite strong evidence for medical therapy in patients with pulmonary arterial hypertension, those options have limited benefit in PH-LHD. Expert PH centres in Canada have been established to provide ongoing care for the more complex patient subgroups.

Abstract
Aims A volume challenge can unmask pulmonary hypertension (PH) and its mechanism. We evaluated the impact of a volume challenge on mean pulmonary artery pressure (mPAP) and mean pulmonary artery wedge pressure (mPAWP) and its prognostic implications in patients with severe aortic stenosis (AS) undergoing aortic valve replacement (AVR). Methods and results In 285 patients with severe AS (indexed aortic valve area 0.41 ± 0.13 cm2/m2), mPAP and mPAWP were measured before and after administration of 150 ± 58 mL of low‐osmolal or iso‐osmolal contrast. Following contrast, mPAP and mPAWP rose from 25 ± 10 and 16 ± 8 mmHg by 5 ± 4 and 4 ± 4 mmHg to 30 ± 11 and 20 ± 8 mmHg. There were 112 (39%) patients with pre‐contrast PH and 70 (40% of those without pre‐contrast PH) patients with post‐contrast PH only. Post‐contrast PH patients were intermediate between pre‐contrast PH and no PH in terms of AS severity, cardiac dysfunction, and haemodynamics. After a median follow‐up of 43 months post‐AVR, pre‐contrast PH patients had numerically the highest mortality driven by those with pre‐contrast combined pre‐capillary and post‐capillary PH (n = 35), while post‐contrast changes in mPAP and mPAWP were not related to mortality. Patients with any post‐contrast mPAWP > 18 mmHg had significantly higher mortality than those with post‐contrast mPAWP ≤ 18 mmHg, Conclusions In severe AS, a contrast challenge leads to post‐contrast PH in ~40% of patients without pre‐contrast PH. However, post‐contrast haemodynamic changes do not adversely affect outcomes in patients undergoing AVR. Post‐contrast PH represents an intermediate stage of ‘cardiac damage’, which may be attenuated or reversible after AVR.

Abstract
We aimed to evaluate the association between pulmonary hypertension (PH) hemodynamic classification and all-cause mortality in patients with symptomatic severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI). PH is common and associated with post-TAVI outcomes in patients with severe AS. Although PH in these patients is primarily driven by elevated left-sided pressures (postcapillary PH), some patients develop increased pulmonary vascular resistance (PVR) configuring the combined pre- and postcapillary PH (CpcPH). We analyzed severe AS patients with mean pulmonary artery pressure (mPAP) measured by right heart catheterization (RHC) before TAVI between 2011 and 2017. PH hemodynamic classification was defined as: No PH (mPAP < 25 mm Hg); precapillary PH (mPAP ≥ 25 mm Hg, pulmonary capillary wedge pressure (PCWP) ≤15 mm Hg); isolated postcapillary PH (IpcPH; mPAP ≥ 25 mm Hg, PCWP > 15 mm Hg, PVR ≤ 3 Wood units (WU); CpcPH (mPAP ≥ 25 mm Hg, PCWP > 15 mm Hg, PVR > 3 WU). Kaplan-Meier and Cox regression analyses were used to test the association of PH hemodynamic classification with post-TAVI all-cause mortality. We examined 561 patients (mean age 82 ± 8 years, 51% men, mean LVEF 54 ± 14%). The prevalence of no PH was 201 (36%); precapillary PH, 59 (10%); IpcPH, 189 (34%); and CpcPH, 112 (20%). During a median follow-up of 30 months, 240 all-cause deaths occurred. Patients with CpcPH had higher mortality than those with no-PH even after adjustment for baseline characteristics (Hazard ratio 1.56, 95% confidence interval 1.06 to 2.29, p = 0.025). There was no survival difference among patients with non-PH, precapillary PH and IpcPH. In conclusion, for patients with symptomatic severe AS treated with TAVI, CcpPH is independently associated with long-term all-cause mortality despite successful TAVI.

Abstract
Importance Severe aortic stenosis causes pressure overload of the left ventricle, resulting in progressive cardiac dysfunction that can extend beyond the left ventricle. A staging system for aortic stenosis has been recently proposed that quantifies the extent of structural and functional cardiac changes in aortic stenosis. Objectives To confirm the reproducibility of a proposed staging system and expand the study findings by performing a survival analysis and to evaluate the association of aortic stenosis staging with both cardiac and noncardiac post-transcatheter aortic valve replacement (TAVR) readmissions. Design, Setting, and Participants A cohort analysis was conducted involving patients with severe aortic stenosis who underwent TAVR at the University of Pittsburgh Medical Center between July 1, 2011, and January 31, 2017. Patients who had undergone TAVR for valve-in-valve procedures and had an incomplete or unavailable baseline echocardiogram study for review were excluded. Clinical, laboratorial, and procedural data were collected from the Society of Thoracic Surgeons database and augmented by electronic medical record review. Exposures The aortic stenosis staging system is based on echocardiographic markers of abnormal cardiac function. The stages are as follows: stage 1 (left ventricle changes - increased left ventricular mass index; early mitral inflow to early diastolic mitral annulus velocity (E/e') >14; and left ventricular ejection fraction <50%), stage 2 (left atrial or mitral changes - left atrial volume index >34 mL/m2; moderate to severe mitral regurgitation; and atrial fibrillation), stage 3 (pulmonary artery or tricuspid changes - pulmonary artery systolic pressure ≥60 mm Hg; moderate to severe tricuspid regurgitation), and stage 4 (right ventricle changes - moderate to severe right ventricle dysfunction). Main Outcomes and Measures Primary outcome was post-TAVR all-cause mortality. Secondary outcomes were composite outcomes of all-cause mortality and post-TAVR all-cause and cardiac-cause readmissions. Results A total of 689 consecutive patients (351 [50.9%] were male, with a mean [SD] age of 82.4 [7.6] years) were included. The prevalence of stage 1 was 13%; stage 2, 62%; stage 3, 21%; and stage 4, 4%. Patients with higher staging had a greater burden of comorbidities as captured by the Society of Thoracic Surgeons Predicted Risk of Mortality (STS-PROM). Despite adjustment for STS-PROM, a graded association was found between aortic stenosis staging and all-cause mortality (hazard ratio [HR] stage 2 vs stage 1: 1.37 [95% CI, 0.81-2.31; P = .25]; stage 3 vs stage 1: 2.24 [95% CI, 1.28-3.92; P = .005]; and stage 4 vs stage 1: 2.83 [95% CI, 1.39-5.76; P = .004]). Stage 3 patients had higher post-TAVR readmission rates for both cardiac (HR, 1.84; 95% CI, 1.13-3.00; P = .01) and noncardiac causes. Conclusions and Relevance Aortic stenosis staging appears to show a strong graded association between the extent of cardiac changes and post-TAVR all-cause mortality; such staging may improve patient care, risk stratification, assessment of prognosis, and shared decision making for patients undergoing TAVR.

Abstract
Pulmonary hypertension (PH) is an important contributor to morbidity and mortality in patients with left-sided heart disease, including valvular heart disease. In this context, elevated left atrial pressure primarily leads to the development of post-capillary PH. Despite the fact that repair of left-sided valvular heart disease by surgical or interventional approaches will improve PH, recent studies have highlighted that PH (pre- or post-interventional) remains an important predictor of long-term outcome. Here, we review the current knowledge on PH in valvular heart disease taking into account new hemodynamic PH definitions, and the distinction between post- and pre-capillary components of PH. A specific focus is on the precise characterization of hemodynamics and cardiopulmonary interaction, and on potential strategies for the management of residual PH after mitral or aortic valve interventions. In addition, we highlight the clinical significance of tricuspid regurgitation, which may occur as a primary condition or as a consequence of PH and right heart dilatation (functional). In this context, proper patient selection for potential tricuspid valve interventions is crucial. Finally, the article highlights gaps in evidence, and points toward future perspectives.

Abstract
This study was performed to investigate the prevalence and impact on survival of baseline mitral stenosis (MS) in patients who underwent transcatheter aortic valve implantation (TAVI) due to the presence of severe symptomatic aortic stenosis. This retrospective study included 928 consecutive patients with severe, symptomatic aortic stenosis who underwent TAVI in 2 institutions, from January 2012 to August 2016. Mean follow-up was 40.8 ± 13.9 months. Based on the mean mitral gradient (MMG) at baseline, 3 groups were identified: MMG <5 mm Hg (n = 737, 81.7%); MMG ≥5 and <10 mm Hg (n = 147, 16.3%); MMG ≥10 mm Hg (n = 17, 1.9%). These latter were more frequently women, with a smaller body surface area, a higher prevalence of atrial fibrillation, chronic obstructive pulmonary disease, and previous history of coronary-artery bypass graft/percutaneous coronary intervention. At baseline, patients with MMG ≥10 mm Hg compared with ≥5 and <10 mm Hg and <5 mm Hg patients had a lower mitral valve area (2.4 ± 0.94 vs 2.1 ± 0.86 vs 1.5 ± 0.44 cm2), a lower prevalence of MR ≥2+ (5.9% vs 28.6% and 15.6%, p <0.0001), a higher prevalence of severe mitral annular calcium (70.6% vs 45.6% and 13.0%, p <0.0001) and a higher systolic pulmonary arterial pressure (50.6 ± 12.1 vs 47.2 ± 14.5 and 41.6 ± 14.4, p <0.0001). Despite the low prevalence of MMG ≥10 mm Hg, these patients had higher 5-year mortality compared with the other groups (adjusted hazard ratio 2.91, 95% confidence interval 1.17 to 7.20, p = 0.02). In conclusion, severe calcific MS is uncommon in patients who underwent TAVI. Its presence is associated with higher long-term mortality whereas moderate MS is not.

Abstract
INTRODUCTION This study was done to review the association of pulmonary hypertension (PH) with Transcatheter Aortic Valve Replacement (TAVR) procedures done in the US for years 2010 to 2012. METHODS We used Nationwide Inpatient Sample (NIS) data to extract data for patients who were hospitalized with a primary/secondary diagnosis of TAVR as specified by International Classification of Disease (ICD-9) codes 35.05 and 35.06. PH was identified with ICD-9 codes 416.0 and 416.8. Logistic regression models were used to analyze the association between PH and clinical outcomes of TAVR. RESULTS A total of 8,824 weighted discharges were identified with a primary/secondary diagnosis of TAVR, of which 1,976 (22.4%) also had PH. Mean age of patients undergoing TAVR with and without PH was 81.4 and 81.1 years, respectively. More females had a diagnosis of PH with TAVR when compared to males, (56.9% vs. 43.1). When controlling for demographics, diabetes and hypertension; the association between PH and TAVR was statistically significant (p<.0001). Estimated odds of TAVR with PH was 5.46 (95% CI: 4.63, 6.41) times greater than for TAVR without PH. Similarly, the estimated odds for a length of stay greater than 1 week for TAVR with PH was 1.43 (95% CI: 1.12, 1.82; p=.0034) times greater than odds for TAVR without PH. PH was not statistically significant for in-hospital mortality in patients receiving TAVR (p=0.7067). CONCLUSION This study suggests that underlying PH does not influence the immediate mortality of patients underlying TAVR. Further studies are needed to delve into the bearing of PH on TAVR.

Haemodynamic mechanisms and long-term prognostic impact of pulmonary hypertension in patients with severe aortic stenosis undergoing valve replacement. Eur J Heart Fail 2018; 21:172-181. [PMID: 30328215 DOI: 10.1002/ejhf.1322] [Citation(s) in RCA: 46] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2018] [Revised: 07/26/2018] [Accepted: 08/27/2018] [Indexed: 01/16/2023] Open
Abstract
AIMS We aimed to investigate the prevalence, detailed invasive haemodynamics, and prognostic impact of pulmonary hypertension (PH) in severe aortic stenosis (AS). METHODS AND RESULTS We studied 503 patients (mean age 74 ± 10 years) with severe AS (indexed aortic valve area 0.4 ± 0.1 cm2 /m2 , left ventricular ejection fraction 57 ± 12%) undergoing left and right heart catheterization prior to aortic valve replacement. Median follow-up was 3.7 (interquartile range 2.6-5.4) years. Baseline PH (mean pulmonary artery pressure ≥ 25 mmHg) was found in 239 (48%) patients: 31 patients had pre-capillary PH [mean pulmonary artery wedge pressure (mPAWP) ≤ 15 mmHg], 144 had isolated post-capillary PH [IpcPH; mPAWP > 15 mmHg, pulmonary vascular resistance (PVR) ≤ 3 Wood units (WU)], and 64 had combined pre- and post-capillary PH (CpcPH; mPAWP > 15 mmHg, PVR > 3 WU). Patients with CpcPH had higher mortality than those with IpcPH, pre-capillary PH, and without PH. In the multivariate analysis, CpcPH remained an independent predictor of death (hazard ratio 4.39, 95% confidence interval 2.40-8.03; P < 0.001). Patients with CpcPH had higher mPAWP (26 ± 7 vs. 22 ± 5 mmHg) and lower pulmonary arterial capacitance (1.5 ± 0.6 vs. 2.9 ± 1.2 mL/mmHg) than IpcPH patients but similar left ventricular end-diastolic pressure (LVEDP; 25 ± 7 vs. 25 ± 7 mmHg). A smaller LVEDP-mPAWP difference was related to larger left atrial size, atrial fibrillation, and more severe mitral regurgitation. CONCLUSIONS In patients with severe AS, PH is common but underlying mechanisms differ. Patients with CpcPH have higher mPAWP, lower pulmonary arterial capacitance, and worse survival than all other groups. Left atrial dysfunction and mitral regurgitation seem to be drivers of high mPAWP in CpcPH.

Abstract
In the summer of 2016, delegates from the German Society of Cardiology (DGK), the German Respiratory Society (DGP), and the German Society of Pediatric Cardiology (DGPK) met in Cologne, Germany, to define consensus-based practice recommendations for the management of patients with pulmonary hypertension (PH). These recommendations were built on the 2015 European Pulmonary Hypertension guidelines, aiming at their practical implementation, considering country-specific issues, and including new evidence, where available. To this end, a number of working groups was initiated, one of which was specifically dedicated to PH associated with left heart disease. In this context, the European Guidelines point out that the drugs currently approved to treat patients with PAH (prostanoids, endothelin receptor antagonists, phosphodiesterase type 5 inhibitors, sGC stimulators) have not sufficiently been investigated in other forms of PH. However, despite the lack of respective efficacy data, an uncritical use of targeted PAH drugs in patients with PH associated with left heart disease is currently observed at an increasing rate. This development is a matter of concern. On the other hand, PH is a frequent problem that is highly relevant for morbidity and mortality in patients with left heart disease. In that sense, the distinction between isolated post-capillary pulmonary hypertension (IpcPH) and combined post- and pre-capillary pulmonary hypertension (CpcPH) and their proper definition may be of particular relevance. The detailed results and recommendations of the working group on PH associated with left heart disease, which were last updated in the spring of 2018, are summarized in this article.

Abstract
OBJECTIVES To evaluate the prognostic value of the ratio between tricuspid annular plane systolic excursion (TAPSE)-pulmonary artery systolic pressure (PASP) as a determinant of right ventricular to pulmonary artery (RV-PA) coupling in patients undergoing transcatheter aortic valve replacement (TAVI). BACKGROUND RV function and pulmonary hypertension (PH) are both prognostically important in patients receiving TAVI. RV-PA coupling has been shown to be prognostic important in patients with heart failure but not previously evaluated in TAVI patients. METHODS Consecutive patients with severe aortic stenosis who received TAVI from July 2011 through January 2016 and with comprehensive baseline echocardiogram were included. All individual echocardiographic images and Doppler data were independently reviewed and blinded to the clinical information and outcomes. Cox models quantified the effect of TAPSE/PASP quartiles on subsequent all-cause mortality while adjusting for confounders. RESULTS A total of 457 patients were included with mean age of 82.8±7.2 years, left ventricular ejection fraction (LVEF) 54%±13%, PASP 44±17 mm Hg. TAPSE/PASP quartiles showed a dose-response relationship with survival. This remained significant (HR for lowest quartile vs highest quartile=2.21, 95% CI 1.07 to 4.57, p=0.03) after adjusting for age, atrial fibrillation, LVEF, stroke volume index, Society of Thoracic Surgeons Predicted Risk of Mortality. CONCLUSION Baseline TAPSE/PASP ratio is associated with all-cause mortality in TAVI patients as it evaluates RV systolic performance at a given degree of afterload. Incorporation of right-side unit into the risk stratification may improve optimal selection of patients for TAVI.

Abstract
In patients with aortic and/or mitral valve disease the presence of pulmonary hypertension (PH) indicates a decompensated state of the disease with left ventricular and left atrial dysfunction and exhausted compensatory mechanism, i.e., a state of heart failure. Pulmonary hypertension in this context is the consequence of the backwards transmission of elevated left atrial pressure. In this form of PH, pulmonary vascular resistance is initially normal (isolated post-capillary PH). Depending on the extent and chronicity of left atrial pressure elevation additional pulmonary vascular remodeling may occur (combined pre- and post-capillary PH). Mechanical interventions for the correction of valve disease often but not always reduce pulmonary pressures. However, the reduction in pulmonary pressures is often modest, and persistent PH in these patients is common and a marker of poor prognosis. In the present review we discuss the pathophysiology and clinical impact of PH in patients with aortic and mitral valve disease, the comprehensive non-invasive and invasive diagnostic approach required to define treatment of PH, and recent insights from mechanistic studies, registries and randomized studies, and we provide an outlook regarding gaps in evidence, future clinical challenges, and research opportunities in this setting.
