A novel method for the evaluation of right ventricular dysfunction in acute pulmonary embolism: Myocardial work indices.

PURPOSE: The presence of right ventricular dysfunction indicates a higher risk status in patients with pulmonary embolism (PE). The RV strain evaluated by speckle-tracking echocardiography seems to be more reliable method in the evaluation of RV dysfunction as compared to standard echocardiographic measures. In this study, we aimed to determine the value of myocardial-work indices in evaluating serial changes of RV function in acute PE. METHODS: Our study comprised 83 consecutive acute PE patients who admitted to our tertiary cardiovascular hospital. Echocardiography was performed within the first 24-hours of hospitalization, and RV and LV myocardial-work parameters were obtained along with standard echocardiographic parameters. The change in the RV/LVr detected on tomography was selected as the primary outcome measure, and its' predictors were analyzed with classical linear regression and a generalized additive model (GAM). RESULTS: Among the LV-RV strain and myocardial work parameters, the RV global longitudinal strain (GLS) has borderline statistical significance in predicting the RV/LVr change whereas the RV global work efficiency (RV-GWE) strongly predicted RV/LVr change (p: 0.049 and <0.001, respectively). CONCLUSION: In this study, classical linear regression and GAM analyses showed that RV-GWE seems to offer a better prediction of RV/LVr change in patients with acute PE.

Temporal association of contamination obsession on the prehospital delay of STEMI during COVID-19 pandemic.

BACKGROUND: One of the modifiable risk factors for ST elevation myocardial infarction is prehospital delay. The purpose of our study was to look at the effect of contamination contamination obsession on prehospital delay compared with other measurements during the Covid-19 pandemic. METHOD: A total of 139 patients with acute STEMI admitted to our heart center from 20 March 2020 to 20 June 2020 were included in this study. If the time interval between the estimated onset of symptoms and admission to the emergency room was >120 min, it was considered as a prehospital delay. The Beck Depression Inventory (BDI), the Beck Anxiety Inventory (BAI), and Padua Inventory-Washington State University Revision (PI-WSUR) test were used to assess Contamination-Obbsessive compulsive disorder (C-OCD). RESULT: The same period STEMI count compared to the previous year decreased 25%. The duration of symptoms onset to hospital admission was longer in the first month compared to second and third months (180 (120-360), 120 (60-180), and 105 (60-180), respectively; P = 0.012). Multivariable logistic regression (model-2) was used to examine the association between 7 candidate predictors (age, gender, diabetes mellitus (DM), hypertension, smoking, pain-onset time, and coronary artery disease (CAD) history), PI-WSUR C-OCD, and admission month with prehospital delay. Among variables, PI-WSUR C-OCD and admission month were independently associated with prehospital delay (OR 5.36 (2.11-13.61) (P = 0.01); 0.26 (0.09-0.87) p < 0.001] respectively]. CONCLUSION: Our study confirmed that contamination obsession was associated with prehospital delay of STEMI patients, however anxiety and depression level was not associated during the pandemic.

Evaluation of subvalvular pannus formation in mechanical aortic valve by transesophageal echocardiography.

Subvalvular pannus formation is a rare but clinically important complication with prosthetic valves. Transthoracic echocardiography still plays a role in the initial assessment of mechanical aortic valve dysfunction. But evaluation with transesophageal echocardiography is more useful. Subvalvular area may be a blind spot of echocardiography due to acoustic shadowing. The case presented herein underlines the significant role of transgastric plane and three-dimensional TEE in the assessment of subvalvular pannus formation in mechanical aortic valves.

Mitral-aortic intervalvular fibrosa pseudoaneurysm causing compression of superior vena cava and right atrium.

The mitral-aortic intervalvular fibrosa (MAIVF) is a fibrous, avascular region between the anterior leaflet of the mitral valve and noncoronary cusp of the aortic valve. This makes MAIVF vulnerable to injury and infection; thus pseudoaneurysm may develop. The pseudoaneurysm can cause compression to coronary arteries which causes angina or pulmonary artery resulting in pulmonary hypertension. We presented the pseudoaneurysm of MAIVF causing compression of superior vena cava and right atrium which was visualized by two- and three-dimensional transesophageal echocardiography and cardiac computed tomography.

Complete Percutaneous Retrieval of Migrated VSD Occluder Device from the Pulmonary Artery: Management of a Catastrophic Complication.

Transcatheter closure of muscular ventricular septal defects (VSD) remains a safe and effective method with low complication rates. However, device migration can pose a significant challenge to interventional cardiologists due to potential mortal consequences. A 21-year-old female presented to our clinic with exertional dyspnea and was diagnosed with a muscular VSD. The defect was percutaneously closed using an Amplatzer occluder device. On the first post-procedural day, the patient experienced repeated episodes of coughing and mild hemoptysis. Imaging revealed migration of the VSD occluder device to the right pulmonary artery (PA). Percutaneous retrieval of the device was then decided upon. The right PA was accessed using a hydrophilic guidewire and a pigtail catheter. This catheter was exchanged for an 8-Fr sheathless guide catheter, and a 6-Fr Judkins right catheter was advanced into the right PA through the sheathless guide catheter using the mother-and-child technique. Multiple attempts using a snare were made to retrieve the migrated device. Eventually, the proximal marker point, the hub of the device, was grasped and pulled back from the PA, then externalized through the sheath without the need for surgical cutdown. Our report represents a case of complete percutaneous retrieval of an embolized VSD occluder device from the PA.

Prognostic Impact of the Tricuspid Annular Plane Systolic Excursion/Pulmonary Arterial Systolic Pressure Ratio in Acute Pulmonary Embolism.

BACKGROUND: Currently available risk stratification models for acute pulmonary embolism (PE) include hemodynamic status, cardiac biomarkers, right ventricle (RV) dysfunction on imaging, and clinical scores. Focusing on the length-tension relationship of the ventricle might have a superior predictive capability over RV dysfunction in terms of mortality and classification of patients with acute PE. In this study, our hypothesis suggests that the tricuspid annular plane systolic excursion (TAPSE)/systolic pulmonary artery pressure (sPAP) ratio has superior predictive capability for in-hospital mortality in patients with acute PE compared to TAPSE or sPAP as distinct measures. METHODS: This single-center study comprised retrospectively evaluated 703 patients referred to our tertiary cardiovascular center with acute PE. We divided patients into quartiles based on the TAPSE/sPAP ratio. Different models were developed to quantify the predictive relationship between in-hospital death and echocardiographic measurements. A base model was created with variables including risk status and RV/LV ratio >1. Then, to evaluate the predictive contribution of each measurement; TAPSE/sPAP, TAPSE, and sPAP were sequentially added to the base model. After that, the performance of each model was evaluated. RESULTS: Predictive and discriminative power was the highest in model containing TAPSE/sPAP. There was still a significant inverse association between TAPSE/sPAP and the risk of in-hospital death even after adjusting for risk status and RV/LV ratio >1. Receiver operating characteristic curve analysis for TAPSE/sPAP revealed the best cut-off value as 0.34. CONCLUSION: The outcomes of our study reveal that the ratio of TAPSE/sPAP serves as a more potent predictor of mortality than either of the 2 measurements taken separately. The interpretation and utilization of the TAPSE/sPAP cut-off value in acute PE can assist in identifying patients at risk of deterioration and guide the consideration of more intensive treatment options across all risk groups.

Long-term cardiovascular outcomes after mini-crush or T and minimal protrusion techniques in complex bifurcation lesions: the EVOLUTE-CRUSH III study.

BACKGROUND: Mini-crush (MC) and T-stenting and small protrusion (TAP) techniques are frequently used, but the long-term comparison of both techniques in patients with complex bifurcation lesions (CBLs) is still a debatable issue. This study sought to retrospectively evaluate the long-term outcomes of MC and TAP techniques in patients with CBLs. METHODS: A total of 271 patients [male: 202 (78.9%), mean age: 58.90 ±â€…10.11 years] patients in whom complex bifurcation intervention was performed between 2014 and 2023 were involved. The primary endpoint was major cardiovascular events (MACE) as the combination of cardiac death, target vessel myocardial infarction, or clinically driven-target lesion revascularization. The Cox proportional hazard models were adjusted by the inverse probability weighting approach to reduce treatment selection bias. RESULTS: The initial management strategy was MC in 146 patients and TAP in 125 cases. MACE occurred in 52 patients (19.2%) during a mean follow-up period of 32.43 ±â€…16 months. The incidence of MACE (13 vs. 26.4%, P = 0.005) and major cardiovascular and cerebral events (15.1 vs. 28.8%, P = 0.006) were significantly lower in the MC group than in the TAP group. Additionally, the incidence of definite or probable stent thrombosis was numerically lower in the MC group compared with the TAP group but did not differ significantly (2.7 vs. 8%, P = 0.059). The long-term MACE was notably higher in the TAP group than the MC group [adjusted hazard ratio (inverse probability weighted): 1.936 (95% confidence interval: 1.053-3.561), P = 0.033]. CONCLUSION: In this study involving patients with CBLs, percutaneous coronary intervention with the MC technique had better long-term outcomes than the TAP technique.

Is it Time to Reappraise for Black-Box Warning on AngioJet Rheolytic Thrombectomy in Patients with Pulmonary Embolism: A Systematic Review and Meta-analysis.

BACKGROUND: AngioJet rheolytic thrombectomy (ART) system has been widely used as a catheter-directed treatment (CDT) method in acute pulmonary embolism (PE), however, there has been a controversy regarding the safety of its use. In this systematic review and meta-analysis, we evaluated the efficacy and safety outcomes of ART in patients with PE. METHODS: Our meta-analysis have been based on search in the MEDLINE, EMBASE, and Cochrane Library for studies published up to August 2022. The primary outcomes were overall pooled rates of major bleeding (MB) and minor bleeding (mB), worsening renal function (WRF), bradycardia/conduction disturbance (BCD), and PE-related and all-cause mortality in patients who underwent ART. RESULTS: Among the 233 studies documented at initial search, 24 studies were eligible for meta-analysis, and a total of 427 PE patients who underwent ART were evaluated. Overall pooled rates of MB and mB were 9.6% (95% CI 5.9%-15.2%) and 9.2% (95% CI 6.1%-13.6%), transient BCD and WRF were 18.2% (95% CI 12.4%-26%) and 15% (95% CI 10%-21.8%), and PE-related death and all-cause death were 12.7% (95% CI 9.1%-17.3%) and 15% (95% CI 11%-20%), respectively. However, significant heterogeneity and some evidence of funnel plot asymmetry and publication bias were noted for MB, BCD and WRF, but not for PE-related death and all-cause death. CONCLUSION: Overall pooled rates of bleeding events, BCD and WRF episodes, PE-related death and all-cause death may be considered as encouraging results for efficacy and safety issues of ART utilization in specific scenarios of acute PE, and a reappraisal for black-box warning on ART seems to be necessary.

Current Insights for Catheter-Directed Therapies in Acute Pulmonary Embolism: Systematic Review and Our Single-Center Experience.

In this review, the current status of the worldwide experience on different catheter-directed treatment systems utilized as alternative reperfusion methods in acute pulmonary-embolism was evaluated, and the risk stratification algorithms in which catheter-directed treatments may be implemented, source of evidence in this setting, adjudication of benefits and risks of available techniques, and innovative multidisciplinary frameworks for referral patterns and care delivery were discussed. Moreover, our perspectives on risk-based catheter-directed treatment utilization strategies in acute pulmonary embolism were summarized.

Hoarseness as a Predictor for Pulmonary Arterial Aneurysm and Extrinsic Left Main Coronary Artery Compression in Patients with Severe Pulmonary Hypertension.

OBJECTIVE: Pulmonary artery (PA) enlargement is a common finding in patients with severe pulmonary hypertension (PH) and may be associated with extrinsic compression of the left main coronary artery (LMCA-Co) and/or compression of the left recurrent laryngeal nerve resulting in hoarseness named as Ortner syndrome (OS). In this study, we evaluated the diagnostic impact of OS in predicting the PA aneurysm and significant LMCA-Co in patients with PH. METHODS: Our study population comprised retrospectively evaluated 865 with PH confirmed with the right heart catheterization between 2006 and 2022. Patients underwent coronary angiography due to several indications, including the presence of a PA aneurysm on echocardiography, angina symptoms, or the incidental discovery of LMCA-Co on multidetector computed tomography. The LMCA-Co is defined as diameter stenosis ³ 50% in reference distal LMCA segment on two consecutive angiographic planes. RESULTS: The LMCA-Co and hoarseness were documented in 3.8% and 4.3% of patients with PH, respectively. Increasing PA diameter was significantly associated with worse clinical, hemodynamic, laboratory, and echocardiographic parameters. The receiver operating curves revealed that the PA diameter >41 mm was cutoff for hoarseness (AUC: 0.834; sensitivity 69%, specificity 84%, and negative predictive value 98%), and PA diameter >35 mm was cutoff for LMCA-Co >50% (AUC: 0.794; sensitivity 89%, specificity 58 %, and negative predictive value 99%). An odds ratio of hoarseness for LMCA-Co was 83.3 (95% confidence interval; 36.5-190, P < 0.001) with 3.2% sensitivity, 98.7% specificity, and 59% positive and 98% negative predictive values. CONCLUSION: In this study, a close relationship was found between the presence of hoarseness and the probability of extrinsic LMCA-Co by enlarged PA in patients with severe PH. Therefore, the risk of LMCA-Co should be taken into account in patients with PH suffering from hoarseness.

A Novel Composed Index to Evaluate the Right Ventricle Free-Wall Adaptation Against Ventricular Wall Stress in Acute Pulmonary Embolism.

BACKGROUND: Pulmonary embolism severity index and simplified pulmonary embolism severity index have been utilized in initial risk evaluation in patients with acute pulmonary embolism. However, these models do not include any imaging measure of right ventricle function. In this study, we proposed a novel index and aimed to evaluate the clinical impact. METHODS: Our study population comprised retrospectively evaluated 502 patients with acute pulmonary embolism managed with different treatment modalities. Echocardiographic and computed tomographic pulmonary angiography evaluations were performed at admission to the emergency room within maximally 30 minutes. The formula of our index was as follows: (right ventricle diameter × systolic pulmonary arterial pressure-echo)/(right ventricle free-wall diameter × tricuspid annular plane systolic excursion). RESULTS: This index value showed significant correlations to clinical and hemodynamic severity measures. Only pulmonary embolism severity index, but not our index value, independently predicted in-hospital mortality. However, an index value higher than 17.8 predicted the long-term mortality with a sensitivity of 70% and specificity of 40% (areas under the curve = 0.652, 95% CI, 0.557-0.747, P =.001). According to the adjusted variable plot, the risk of long-term mortality increased until an index level of 30 but remained unchanged thereafter. The cumulative hazard curve also showed a higher mortality with high-index value versus low-index value. CONCLUSIONS: Our index composed from measures of computed tomographic pulmonary angiography and transthoracic echocardiography may provide important insights regarding the adaptation status of right ventricle against pressure/wall stress in acute pulmonary embolism, and a higher value seems to be associated with severity of the clinical and hemodynamic status and long-term mortality but not with in-hospital mortality. However, the pulmonary embolism severity index remained as the only independent predictor for in-hospital mortality.

Reappraisal of the Transthoracic Echocardiographic Algorithm in Predicting Pulmonary Hypertension Redefined by Updated Pulmonary Artery Mean Pressure Threshold.

BACKGROUND: Although an adopted echocardiography algorithm based on tricuspid regurgitation jet peak velocity and suggestive findings for pulmonary hypertension has been utilized in the non-invasive prediction of pulmonary hypertension probability, the reliability of this approach for the updated hemodynamic definition of pulmonary hypertension remains to be determined. In this study, for the first time, we aimed to evaluate the tricuspid regurgitation jet peak velocity and suggestive findings in predicting the probability of pulmonary hypertension as defined by mean pulmonary arterial pressure > 20 mm Hg and > 25 mm Hg, respectively. METHODS: Our study group was comprised of the retrospectively evaluated 1300 patients (age 53.1 ± 18.8 years, female 62.1%) who underwent right heart catheterization with different indications between 2006 and 2018. All echocardiographic and right heart catheterization assessments were performed in accordance with the European Society of Cardiology/European Respiratory Society 2015 Pulmonary Hypertension Guidelines. RESULTS: Although tricuspid regurgitation jet peak velocity showed a significant relation with mean pulmonary arterial pressure in both definitions, suggestive findings offered a significant contribution only in predicting mean pulmonary arterial pressure ≥ 25 mm Hg but not for mean pulmonary arterial pressure > 20 mm Hg. In predicting the mean pulmonary arterial pressure > 20 mm Hg, tricuspid regurgitation jet peak velocity and suggestive findings showed an odds ratio of 2.57 (1.59-4.14, P <.001) and 1.25 (0.86-1.82, P =.16), respectively. In predicting the mean pulmonary arterial pressure ≥ 25 mm Hg, tricuspid regurgitation jet peak velocity, and suggestive findings showed an odds ratio of 2.33 (1.80-3.04, P <.001) and 1.54 (1.15-2.08, P <.001), respectively. The tricuspid regurgitation jet peak velocity > 2.8 m/s and tricuspid regurgitation jet peak velocity > 3.4 m/s were associated with 70% and 84% probability of mean pulmonary arterial pressure > 20 mm Hg and 60% and 76% probability of mean pulmonary arterial pressure ≥ 25 mm Hg, respectively. CONCLUSIONS: In contrast to those in predicting the mean pulmonary arterial pressure ≥ 25 mm Hg, suggestive findings did not provide a significant contribution to the probability of mean pulmonary arterial pressure > 20 mm Hg predicted by tricuspid regurgitation jet peak velocity solely. The impact of the novel mean pulmonary arterial pressure threshold on the echocardiographic prediction of pulmonary hypertension remains to be clarified by future studies.

A New Index for the Prediction of In-Hospital Mortality in Patients with Acute Pulmonary Embolism: The Modified Shock Index.

BACKGROUND: Pulmonary embolism severity index, its simplified version, and shock index have been used for risk stratification in acute pulmonary embolism. In this study, we proposed a modification in severity index and evaluated the correlates and prognostic value of modification in severity index in this setting. METHODS: The study group comprised retrospectively evaluated 181 patients with acute pulmonary embolism. Systematic workup including pulmonary embolism severity index, its simplified version, shock index, biomarkers, and echocardiographic and multidetector computed tomography assessments was performed in all patients. Moreover, we calculated modification in severity index by multiplying original shock index (heart rate/systolic blood pressure ratio) and a third component, 1/pulse oxymetric saturation (pSat O2%) ratio. The primary endpoint was defined as all-cause mortality and hemodynamic collapse during the hospital stay. RESULTS: On the basis of initial risk stratification, ultrasound-assisted thrombolysis, systemic tissue-type plasminogen activator, and unfractionated heparin therapies were utilized in 83 (45.9%), 37 (20.4%), and 61 (33.7%) patients, respectively. The primary end-point occurred in 13 (7.2%) patients. Receiver-operating curve analysis revealed that modification in severity index had the highest area under the curve of 0.739 (0.588-0.890, P =.002) compared with shock index, pulmonary embolism severity index, or its simplified version. The modification in severity index > 0.989 predicted primary endpoint with 73% sensitivity and 54% specificity. CONCLUSIONS: The modification in severity index seems to be a simple, quick, and compre-hensive risk assessment tool for bedside evaluation at initial stratification, in monitoring the clinical benefit from therapies, and decision-making for escalation to other reperfusion strategies in patients with acute pulmonary embolism. However, the prognostic value of modification in severity index needs to be validated with further studies.

Remembering the Occam's Razor: Could Simple Electrocardiographic Findings Provide Relevant Predictions for Current Hemodynamic Criteria of Pulmonary Hypertension?

BACKGROUND: We evaluated the predictive value of electrocardiographic (ECG) findings for pulmonary hemodynamics assessed by right heart catheterization (RHC). METHODS: Our study population comprised 562 retrospectively evaluated patients who underwent RHC between 2006 and 2022. Correlations between ECG measures and pulmonary arterial systolic and mean pressures (PASP and PAMP) and pulmonary vascular resistance (PVR) were investigated. Moreover, receiver operating characteristic (ROC) curve analysis assessed the predictive value of ECG for pulmonary hypertension (PH) and precapillary PH. RESULTS: The P-wave amplitude (Pwa) and R/S ratio (r) in V1 and V2, Ra in augmented voltage right (aVR), right or indeterminate axis, but not P wave duration (Pwd) or right bundle branch block (RBBB) significantly correlated with PASP, PAMP, and PVR (P <.001 for all). The partial R2 analysis revealed that amplitude of R wave (Ra) in aVR, R/Sr in V1 and V2, QRS axis, and Pwa added to the base model provided significant contributions to variance for PASP, PAMP, and PVR, respectively. The Pwa > 0.16 mV, Ra in aVR > 0.05 mV, QRS axis > 100° and R/Sr in V1 > 0.9 showed the highest area under curve (AUC) values for PAMP > 20 mm Hg. Using the same cutoff value, Ra in aVR, Pwa, QRS axis, and R/Sr in V1 showed highest predictions for PVR > 2 Wood Units (WU). CONCLUSION: In this study, Pwa, Ra in aVR, right or indeterminate axis deviations, and R/Sr in V1 and V2 showed statistically significant correlations with pulmonary hemodynamics, and Ra in aVR, R/Sr in V2 and V1, QRS axis, and Pwa contributed to variance for PASP, PAMP, and PVR, respectively. Moreover, Pwa, Ra in aVR, QRS axis, and R/Sr in V1 seem to provide relevant predictions for PH and precapillary PH.

Clinical, imaging and hemodynamic correlates and prognostic impact of syncope in acute pulmonary embolism: A single-center study.

Background: We aimed to determine the clinical, echocardiographic and hemodynamic correlates of syncope as a presenting symptom in pulmonary embolism and its impact on in-hospital and long-term outcomes. Methods: Between July 2012 and October 2019, a total of 641 patients with PE (277 males, 364 females; median age: 65 years; range, 51 to 74 years) in whom the diagnostic work-up and risk-based management were performed according to the current pulmonary embolism guidelines were retrospectively analyzed. Clinical, laboratory and imaging data of the patients were obtained from hospital database system. Results: Syncope was noted in 193 (30.2%) of patients on admission, and was associated with a significantly higher-risk status manifested by elevated troponin and D-dimer levels, a higher Pulmonary Embolism Severity Index scores, deterioration of right-to-left ventricular diameter ratio, right ventricular longitudinal contraction measures, the higher Qanadli score, and higher rates of thrombolytic therapies (p<0.001) and rheolytic-thrombectomy (p=0.037) therapies. In-hospital mortality (p=0.007) and minor bleeding (p<0.001) were significantly higher in syncope subgroup. Multivariate logistic regression analysis showed that higher Pulmonary Embolism Severity Index scores and right-to-left ventricular diameter ratio were independently associated with syncope, while aging and increased heart rate predicted in-hospital mortality. Malignancy and right-to-left ventricular diameter ratio at discharge, but not syncope, were independent predictors of cumulative mortality during follow-up. Conclusion: Syncope as the presenting symptom is associated with a higher risk due to more severe obstructive pressure load and right ventricular dysfunction requiring more proactive strategies in patients with pulmonary embolism. However, with appropriate risk-based therapies, neither in-hospital mortality nor long-term mortality can be predicted by syncope.

Maternal and Fetal Outcomes in Pregnant Women with Pulmonary Arterial Hypertension: A Single-Center Experience and Review of Current Literature.

BACKGROUND: Although pregnancy in women with pulmonary arterial hypertension has been considered a high-risk condition, current data regarding pregnancy with pulmonary arterial hypertension are scarce. In this study, we aimed to evaluate our single-center data on maternal and fetal outcomes in pregnant women with PAH and review currently available risk-based management strategies. METHODS: Our single-center study group comprised 35 women who became pregnant after the diagnosis of pulmonary arterial hypertension or in whom pulmonary arterial hypertension was diagnosed within early post-partum period. Clinical, laboratory, echocardiographic, and hemodynamic characteristics of pregnant and non-pregnant productive women with pulmonary arterial hypertension were compared, and similar comparison was also repeated for survivors and non-survivors in pregnant patient group. RESULTS: Pregnancy was noted in 15% of the 228 females with pulmonary arterial hypertension who were of hormonally productive ages, generally well-tolerated until delivery. Elective abortion and pre-term delivery were documented in 1 (2.8%) and 12 (35.3%) pregnant women, respectively. Switching to sildenafil was the standard medication during pregnancy. Cesarian section was the preferred method of delivery in all pregnant women with pulmonary arterial hypertension and was performed without any complication. Clinic deteoriation within the first week of delivery was observed in 5 (41.6%) patients. Maternal mortality was noted in 13 (37.1%) patients and was documented to cumulate within the first month of delivery. However, any sign predicting post-partum clinical deterioration was not found. No fetal mortality was observed. CONCLUSION: Despite the development of advanced therapies, pregnancy in pulmonary arterial hypertension still carries a high mortality risk and requires multi-disciplinary expert center care with more proactive management strategies.

The Consistent Effectiveness and Safety of Macitentan Therapies Across Idiopathic and Congenital Heart Disease-Associated PulmonaryArterial Hypertension: A Single-Center Experience.

BACKGROUND: In this single-center study, we evaluated efficacy and safety issues and predictors of survival in patients with idiopathic and congenital heart disease-associated pulmonary arterial hypertension who were under macitentan therapies. METHOD: Our study retrospectively evaluated 221 patients with pulmonary arterial hypertension enrolled in our single-center study, and mono, dual, and triple macitentan therapies were noted in 30, 115, and 76 patients, respectively. The longitudinal changes in clinical, neurohumoral, and echocardiographic measures of pulmonary arterial hypertension were evaluated. The Registry to Evaluate Early and Long-Term Pulmonary Arterial Hypertension Disease Management, Registry to Evaluate Early and Long-Term Pulmonary Arterial Hypertension Disease Management 2.0, and Registry to Evaluate Early and Long- Term Pulmonary Arterial Hypertension Disease Management Lite 2 scores at baseline, Swedish PAH Registry, Comparative Prospective Registry of Newly Initiated Therapies for Pulmonary Hypertension registry, and French Pulmonary Hypertension Network registry risk status both at baseline and first control were assessed. RESULT: The median follow-up period was 1068 [415-2245] days. Macitentan was associated with significant improvements in functional class, 6-minute walk distance, N-terminal pro-brain natriuretic peptide (NT-proBNP), and echocardiographic measures without any deterioration of hemoglobin or hepatic enzymes. The low-risk scores with each model at baseline and/or first control are related to significantly better survival. Age, gender, and log-NT-proBNP in time-fixed and idiopathic pulmonary arterial hypertension, and log-NT-proBNP in time-dependent Cox proportional hazard regression analyses were independent predictors of mortality. CONCLUSION: Mono- or sequential combination macitentan therapies were associated with sustained benefits in functional class, 6-minute walk distance, NT-proBNP, and echocardiographic measures in patients with idiopathic pulmonary arterial hypertension and congenital heart disease-associated pulmonary arterial hypertension, and low-risk scores at baseline and/or first controls can be translated to better survival.

Eosinophil-to-Monocyte Ratio as a Candidate for a Novel Prognostic Marker in Acute Pulmonary Embolism: Is it a Consumptive Mechanism?

BACKGROUND: The role of eosinophils in thrombotic processes is well known, and the prognostic value of eosinophil to monocyte ratio had been determined in patients with ST elevated myocardial infarction and acute ischemic stroke in recent studies. We aimed to evaluate the impact of the eosinophil-to-monocyte ratio on short- and long-term allcause mortality in patients with pulmonary embolism, which is another clinical condition closely related to the thrombotic pathway. METHODS: In this study, a total of 212 retrospectively evaluated patients with intermediate-high risk and high-risk pulmonary embolism who underwent catheter-directed therapies with ultrasound-assisted thrombolysis or rheolytic thrombectomy (Angiojet©) and intravenous thrombolytic treatment were included. RESULTS: The median Pulmonary Embolism Severity Index score was 105 (86-128; interquartile range: 25-75, min-max: 35-250). The intermediate-high status and high-risk status were noted in 83.5% and 16.5% of the patients, respectively. All of the reperfusion strategies resulted in significant improvements in the measures of pulmonary arterial pressure and right ventricular strain. Death was recorded in 42 (18.6%) patients during the follow-up period (median 1029 days, interquartile range: 651-1358). Multiple Cox regression analysis revealed that a higher pulmonary embolism severity index score (from 85 to 128; hazard ratio=3.00; 95% CI: 2.11-4.29; P < .001) and a lower eosinophil-to-monocyte ratio (from 0.02 to 0.24; hazard ratio=0.56; 95% CI: 0.34-0.98; P = .032) were 2 independent predictors for long-term all-cause mortality. The eosinophil-to-monocyte ratio at the admission of less than 0.03 was documented to be associated with higher mortality (P < .001). CONCLUSION: Our results revealed that a lower eosinophil-to-monocyte ratio and a higher pulmonary embolism severity index score independently predict the long-term mortality in patients with intermediate-high- and high-risk pulmonary embolism.

An Eight-year, Single-center Experience on Ultrasound Assisted Thrombolysis with Moderate-dose, Slow-infusion Regimen in Pulmonary Embolism.

BACKGROUND: There is limited data on moderate-dose with slow-infusion thrombolytic regimen by ultrasound-asssisted-thrombolysis (USAT) in patients with acute pulmonary embolism (PE). AIMS: In this study, our eight-year experience on USAT with moderate-dose, slow-infusion tissue-type plasminogen activator (t-PA) regimen in patients with PE at intermediate-high- and high-risk was presented, and short-, and long-term effectiveness and safety outcomes were evaluated. METHODS: Our study is based on the retrospective evaluation of 225 patients with PE having multiple comorbidities who underwent USAT. RESULTS: High- and intermediate-high-risk were noted in 14.7% and in 85.3% of patients, respectively. Mean t-PA dosage was 35.4±13.3 mg, and the infusion duration was 26.6±7.7 h. Measures of pulmonary artery (PA) obstruction and right ventricle (RV) dysfunction were improved within days (p<0.0001 for all). During the hospital stay, major and minor bleeding and mortality rates were 6.2%, 12.4%, and 6.2%, respectively. Bleeding and unresolved PE accounted for 50% and 42.8% of in-hospital mortality, respectively. Age, rate, and duration of t-PA were not associated with in-hospital major bleeding and mortality. Oxygen saturation exceeded 90% in 91.2% of patients at discharge. During follow-up of median 962 (610-1894) days, high-risk status related to 30-day mortality, whereas age >65 years was associated with long-term mortality. CONCLUSION: Our real-life experience with USAT with moderate-dose, slow-infusion t-PA regimen in patients with PE at high-and intermediate-high risk demonstrated clinically relevant improvements in PA obstructive burden and RV dysfunction. Age, rate or infusion duration of t-PA was not related to major bleeding or mortality risk, whereas unresolved obstruction remained as a lethal issue.

Unicuspid aortic valve with false aortic dissection appearance: A case report.

Unicuspid aortic valve (UAV) is a rare congenital anomaly that usually presents with aortic stenosis or mixed stenosis and regurgitation early in life. Ascending aortic aneurysm and aortic dissection are important complications of UAVs. A 27-year-old man presented to the emergency department with a complaint of acute chest pain. Bedside transthoracic echocardiography (TTE) showed dilatation of ascending aorta (47 mm) and mild aortic regurgitation; computed tomography (CT) angiography revealed a suspicious dissection flap within ascending aorta. A cardiovascular surgeon, a radiologist, and a cardiologist were immediately consulted. TTE performed by the cardiologist revealed a unicuspid unicommissural aortic valve and dilated ascending aorta with no signs of dissection. Aortic dissection image on CT angiogram was interpreted by an experienced radiologist and the cardiovascular surgeon as superior pericardial recess and considered as a false-positive dissection image. Given the patient was pain-free, the CT image was considered false positive and as TTE clearly visualized the ascending aorta, the heart team decided that no further imaging is required. After excluding acute aortic syndrome, acute coronary syndrome, and other causes of acute chest pain, the patient was discharged with close follow-up. Diagnosis of aortic dissection is based on noninvasive imaging modalities, and CT is the first-line imaging choice in most emergency departments. Depending on a single imaging modality may cause false interpretations and lead to unnecessary surgical explorations.
