Development of preeclampsia in pregnant women with white-coat hypertension: a systematic review and meta-analysis.

OBJECTIVE: Hypertensive disorders during pregnancy are a significant cause of maternal and perinatal mortality and morbidity worldwide. White coat hypertension (WCH) is a hypertensive disease characterized by an increased clinic blood pressure but normal home or workplace blood pressure. Due to variable prevalence, a subset of women with WCH may be incorrectly diagnosed with chronic hypertension, highlighting the need for accurate diagnosis. Little is known about the role of WCH in pregnancy, but a meta-analysis aims to determine whether WCH increases the likelihood of developing preeclampsia. METHODS: A systematic review and meta-analysis was conducted to determine whether there is an association between WCH and the incidence of preeclampsia in pregnant women. The search included PubMed, Embase, and Scopus databases until February 2023, using PRISMA guidelines. Pregnant women with apparent office hypertension throughout pregnancy who underwent 24-hour ambulatory blood pressure monitoring or home blood pressure monitoring were included. Meta-analysis was performed using RevMan. RESULTS: This study included 12 studies with a total of 4,672 pregnant women and found that women with WCH have a higher risk of developing preeclampsia compared to normotensive women (RR: 2.29, 95% CI [1.18,4.43], P = 0.01). However, when compared with pregnant women with gestational hypertension or chronic hypertension, women with WCH had a significantly lower risk of developing preeclampsia ((RR: 0.39, [0.20,0.80], p=0.009) and (RR: 0.41, [0.27,0.62], P<0.001), respectively). CONCLUSION: The study recommends incorporating 24-hour ABPM into clinical practice to differentiate between chronic hypertension and WCH in early pregnancy and focus on special management for those who need it. The findings may guide future research on ABPM's role in diagnosing WCH and its effects on pregnancy outcomes.

Correlation between Heart rate recovery and Left Atrial phasic functions evaluated by 2D speckle-tracking Echocardiography after Acute Myocardial infarction.

BACKGROUND: Heart rate recovery (HRR) in the exercise test is the index of cardiac autonomic system function and sympathovagal balance impaired in patients with myocardial infarction (MI). An instance is left atrial (LA) phasic function, which is impaired in such patients. In this study, we investigated the role of HRR in predicting LA phasic functions in patients with MI. METHODS: The present study recruited 144 consecutive patients with ST-elevation MI. A symptom-limited exercise test was performed about 5 weeks after MI, with echocardiography conducted just before the exercise test. The patients were divided into abnormal and normal HRR at 60 s (HRR60) and again into abnormal and normal HRR at 120 s (HRR120) after the exercise test. LA phasic functions, evaluated by 2D speckle-tracking echocardiography, were compared between the 2 groups. RESULTS: Patients with abnormal HRR120 had lower LA strain values and strain rates during the reservoir, conduit, and contraction phases, while those with abnormal HRR60 had lower LA strain values and strain rates during the reservoir and conduit phases. The differences were lost after adjustments for possible confounders, except for LA strain and strain rate during the conduit phase, in patients with abnormal HRR120. CONCLUSIONS: Abnormal HRR120 in the exercise test can independently predict decreased LA conduit function in patients with ST-elevation MI.

Evaluation of the right atrial phasic functions in patients with anterior ST-elevation myocardial infarction: a 2D speckle-tracking echocardiography study.

BACKGROUND: Evidence suggests that changes in left ventricular systolic and diastolic functions may affect right atrial (RA) phasic functions. We aimed to evaluate RA phasic functions in the presence of anterior ST-elevation myocardial infarction (ASTEMI) as an acute event and to compare the findings with those in a control group. METHODS: We recruited 92 consecutive ASTEMI patients without accompanying significant stenosis in the proximal and middle parts of the right coronary artery and 31 control subjects, matched for age, sex, diabetes, and hypertension. RA phasic functions were evaluated concerning their longitudinal 2D speckle-tracking echocardiography-derived markers. The ASTEMI group was followed up for all-cause mortality or reinfarction. RESULTS: In the ASTEMI group, RA strain was reduced during the reservoir (33.2% ± 4.3% vs 30.5% ± 8.1%; P = 0.021) and conduit (16% [12-18%] vs 14% [9-17%]; P = 0.048) phases. The other longitudinal 2D speckle-tracking echocardiography-derived markers of RA phasic functions were not different between the 2 groups. RA strain and strain rate during the contraction phase were predictive of all-cause mortality or reinfarction (hazard ratio = 0.80; P = 0.024 and hazard ratio = 0.39; P = 0.026, respectively). CONCLUSIONS: Based on 2D speckle-tracking echocardiography, in the ASTEMI group, compared with the control group, RA reservoir and conduit functions were reduced, while RA contraction function was preserved. RA contraction function was predictive of all-cause mortality or reinfarction during the follow-up period.

Assessment of the ability of the CHA2DS2-VASc scoring system to grade left atrial function by 2D speckle-tracking echocardiography.

BACKGROUND: The CHA2DS2-VASc scoring system is correlated with left atrial (LA) reservoir function in patients with atrial fibrillation (AF) rhythm or paroxysmal AF. We assessed the ability of CHA2DS2-VASc to grade LA function in patients with sinus rhythm who were candidates for coronary artery bypass grafting (CABG). METHODS: This cross-sectional study recruited 340 consecutive candidates for CABG and categorized them according to their CHA2DS2-VASc scores as mild-, moderate-, and high-risk score groups with 34 (10%), 83 (24%), and 223 (66%) patients, respectively. LA function was evaluated via 2D speckle-tracking echocardiography in terms of global longitudinal strain and strain rate during the reservoir, conduit, and contraction phases. In-hospital mortality, postoperative AF, prolonged intensive care unit (ICU) stay, and prolonged mechanical ventilation were assessed. RESULTS: LA strain and strain rate during the reservoir phase was statistically significantly lower in the high-risk score group than the low- and moderate-risk score groups (27.8 ± 6.9% vs 31.0 ± 5.0% vs 29.8 ± 6.1%, respectively; P = 0.004 and 2.6 ± 0.7 s-1 vs 2.9 ± 0.6 s-1 vs 2.9 ± 0.6 s-1, correspondingly; P = 0.009) and regarding LA strain and strain rate during the conduit phase (9.7 [7.1-12.5]% vs 12.9 [9.4-15.1]% vs 11.5 [9.1-13.8]%, correspondingly; P < 0.001 and 2.1 [1.6-2.7] s-1 vs 2.8 [2.4-3.6] s-1 vs 2.6 [2.2-3.0] s-1, respectively; P < 0.001). In addition, LA strain rate during the conduit phase was lower in the moderate-risk score group than the low-risk score group. After adjustments for possible confounders, these differences remained statistically significant. The risk of postoperative AF and prolonged ICU stay was highest in the high-risk score group (relative risk = 9.67 (1.31-71.43) and 8.05 (1.08-60.16), respectively; P = 0.026 and P = 0.042, respectively). CONCLUSIONS: LA reservoir and conduit functions decreased in the high-risk score group, which was accompanied by an increased risk of postoperative AF and prolonged ICU stay.

Intrapericardial solitary fibrous tumor: A case report and review of literature.

Solitary fibrous tumor (SFT) is a mesenchymal neoplasm mostly originates from pleura, but rarely from other parts of the body including pericardium. We report a case of a 44-year-old woman with dyspnea and intermittent edema in whom a large intrapericardial mass was discovered by echocardiography. Computed tomography (CT) revealed a focal pericardial calcification in right AV grove with pressure on right ventricle and right atrial, with no connection to cardiac chambers. Histopathological findings after complete resection of the mass revealed fibroconnective tissue with heavy calcification and no evidence of inflammation or malignancy. We reviewed the literature on pericardial solitary fibrous tumors up to 2020.

Interaction effect of myocardial infarction and obesity on left atrial functions.

PURPOSE: To determine whether myocardial infarction (MI) would lead to a greater decrease in left atrial (LA) functions in subjects with than without obesity. METHODS: A total of 310 consecutive patients were divided into four groups according to the presence or absence of obesity and MI. The functions of the LA were evaluated in terms of longitudinal deformation of the LA myocardium via 2D speckle-tracking echocardiography. RESULTS: The adjusted analysis showed a reduction in the strain and strain rate during the reservoir and contraction phases and in the strain rate during the conduit phase in patients with MI and in subjects with obesity (P < .05). In addition, there was a significant interaction effect of obesity and MI on the strain rate during the contraction phase (P = .048). CONCLUSIONS: There is an independent and additional interaction effect of obesity and MI on the reservoir and conduit functions of the LA. MI was more deleterious to the contraction function in subjects without than with obesity, so that the contraction function was similar in MI patients without obesity and MI patients with obesity.

A pseudoaneurysm of the left atrium as a rare source of coronary artery embolization.

A 67 years old woman with history of surgical Mitral valve replacement underwent transoesophageal echocardiography for evaluation of mild dyspnoea. It revealed a large narrow-necked outpouching from medial portion of the inferior wall of the left atrium (LA) that was extended to the interatrial septum. A diagnosis of the LA pseudoaneurysm was made. It contained a fresh clot. Five days later, the patient presented with an acute inferior ST-elevation myocardial infarction. Coronary angiography revealed an occluded right coronary artery at its distal part by a large thrombus. Thromboaspiration was done and resulted in restoration of a Thrombolysis in Myocardial Infarction Score (TIMI) flow 3 without underlying stenosis.

Effects of vitamin D deficiency on left atrial function as evaluated by 2D speckle-tracking echocardiography.

PURPOSE: Vitamin D deficiency is prevalent the world over, and some of its effects on the cardiovascular system have been previously demonstrated. We evaluated left atrial (LA) function via 2D speckle-tracking echocardiography (2DSTE) in subjects with and without vitamin D deficiency. METHODS: Ninety-seven consecutive patients without significant coronary artery disease on selective coronary angiography were incorporated in our study and divided according to their serum level of vitamin D into 2 groups: with and without vitamin D deficiency. RESULTS: The early diastolic strain rate, as a marker of LA conduit function, was increased in patients with vitamin D deficiency (P = .008) and after adjustment for age (P = .046). However, after adjustment for all the confounding factors, vitamin D deficiency showed only a trend to be the independent determinant of LA early diastolic longitudinal strain rate (SRE, P = .065). CONCLUSIONS: Our findings indicated that LA function, as evaluated by 2DSTE, was not different between subjects with and without vitamin D deficiency after adjustment for the confounding factors.

Impaired Left Atrial Conduit Function in Coronary Artery Disease Patients With Poorly Controlled Diabetes: Two-Dimensional Speckle-Tracking Echocardiographic Study.

OBJECTIVES: The myocardium can be affected by diabetes mellitus. The effects of blood glucose control on some organs such as the kidney and eye have been previously reported. The aim of our study was to evaluate left atrial function via 2-dimensional (2D) speckle-tracking echocardiography in a group of coronary artery disease (CAD) patients with well-controlled diabetes (hemoglobin A1c [HbA1c] < 7%) and to compare it with that in a group of CAD patients with poorly controlled diabetes. METHODS: This cross-sectional study included 110 CAD patients, comprising 44 euglycemic control patients, 33 patients with well-controlled diabetes (HbA1c < 7%), and 33 patients with poorly controlled diabetes. The study population thereafter underwent 2D speckle-tracking echocardiography for an evaluation of their left atrial function. RESULTS: Our findings showed that the absolute values of early diastolic strain and early diastolic strain rate were lower in the CAD patients with poorly controlled diabetes than in the euglycemic control patients with CAD. Moreover, early diastolic strain in the CAD patients with poorly controlled diabetes was lower than that in the CAD patients with well-controlled diabetes. Multivariable analysis revealed that poorly controlled diabetes was an independent determinant of early diastolic strain and strain rate. CONCLUSIONS: The conduit function of the left atrium was impaired in the CAD patients with poorly controlled diabetes compared with that in the euglycemic control patients with CAD and the CAD patients with well-controlled diabetes.

Evaluation of left atrial function via two-dimensional speckle-tracking echocardiography in patients with coronary artery ectasia.

BACKGROUND: Coronary artery ectasia (CAE) is a segmental dilation of an epicardial coronary artery. Our aim was to evaluate the left atrial (LA) function in patients with CAE. METHODS: Twenty-seven consecutive patients with CAE and 33 subjects without significant coronary artery disease were included in our study. LA function was evaluated with two-dimensional speckle-tracking echocardiography (2DSTE). RESULTS: The systolic, early diastolic and late diastolic strains and strain rates were not statistically significantly different between the two groups. CONCLUSIONS: Our findings demonstrated that LA function may not be affected by CAE when assessed with 2DSTE. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 45:231-237, 2017.

Complications of transcatheter paravalvular leak device closure of mitral valve: An updated review of the literature and a rare case presentation.

Paravalvular leak (PVL) is an uncommon complication of prosthetic valve implantation, which can lead to infective endocarditis, heart failure, and hemolytic anemia. Surgical reintervention of PVLs is associated with high mortality rates. Transcatheter PVL closure (TPVLc) has emerged as an alternative to surgical reoperation. This method provides a high success rate with a low rate of complications. This article reviews the pathogenesis, clinical manifestation, diagnosis, and management of PVL and complications following TPVLc. Besides, we presented a case of a patient with severe PVL following mitral valve replacement, who experienced complete heart block (CHB) during TPVLc. The first TPVLc procedure failed in our patient due to possible AV-node insult during catheterization. After 1 week of persistent CHB, a permanent pacemaker was implanted. The defect was successfully passed using the previous attempt. Considering the advantages of TPVLc, procedure failure should be regarded as a concern. TPVLc should be performed by experienced medical teams in carefully selected patients.

Transhepatic Access for Percutaneous Mitral Balloon Commissurotomy With Dextrocardia and Inferior Vena Cava Interruption.

We report a successful percutaneous mitral balloon commissurotomy via left transhepatic venous access in a 42-year-old female patient with dextrocardia, situs inversus totalis, and inferior vena cava interruption. fWe also discuss the revisions required for optimal trans-septal approach from the left transhepatic vein.

Short and mid-term outcomes of valve-sparing, aortic root reimplantation (David's procedure).

BACKGROUND: In the current study, we aimed to report the short- and mid-term outcomes of patients undergoing valve-sparing aortic root reimplantation (VSARR) and our center's experience with the procedure. METHODS: Forty patients with aortic root aneurysms underwent VSARR at our center from 2010 until 2022. We retrospectively reviewed the medical records of these patients and extracted the relevant data. After carefully examining the aortic valve, the surgeon decided to perform Bentall or David's procedure during the operation. RESULTS: The study population comprised 31 (77.5%) men and nine (22.5%) women, with a mean age of 55.35 ± 15.40. One patient developed hemodynamic instability post-surgery in the hospital and died from multi-organ failure. Another patient had severe AI in the intraoperative echocardiography, and aortic valve replacement with a prosthetic graft was performed during the same operation. In pre-operation echocardiography, 25 (62.5%) patients had severe, nine (22.5%) had moderate, and six (15%) had mild AI. In the in-hospital post-operation follow-up echo, AI was improved, and no patients had severe AI (P < 0.001). Only eight patients had moderate AI in post-one-year follow-up echo exams, while the rest had mild AI. CONCLUSION: David's procedure showed excellent mid-term results in our center, with only one in-hospital mortality.

Non-Compaction Ventricle and Associated Cardiovascular and Non-Cardiovascular Diseases; More Attention Is Needed!

Non-compaction of the ventricle (NCV) with a higher tendency to left ventricular involvement (NCLV) is a genetic disorder which can cause arrhythmias and cardiac arrest or remain asymptomatic. It is generally considered an isolated disease most frequently, while a few case reports have reported its association with cardiac anomalies. As the treatment strategies differ for NCV and cardiac anomalies, missed diagnosis of the concomitant cardiac diseases can result in poor response to treatment and prognosis. Here, we present 12 adult patients diagnosed with NCV and associated cardiovascular anomalies. By increasing the clinical suspicion and physician's awareness about the possibility of the presence of other cardiovascular diseases with NCLV and using close examination and follow-up of the patients, we could diagnose this number of patients during 14 months of investigation. This case series emphasizes the need for increased awareness and attention of echocardiographers on the diagnosis of other cardiovascular diseases associated with NCV for a better response to treatment and improved patient prognosis.

Determinants of the Volumetric Markers of Left Atrial Contraction Function in Coronary Artery Disease: A Cross-sectional Study.

BACKGROUND: A body of research advocates the prognostic role and usefulness of the volumetric markers of left atrial (LA) phasic functions in the diagnosis of LA dysfunction. We aimed to determine the independent determinants of the volumetric markers of LA contraction function in candidates for coronary artery bypass graft (CABG) surgery. METHODS: This cross-sectional study enrolled 516 candidates for CABG. The biplane maximal, minimal, and pre-P volumes of the LA were measured with two-dimensional echocardiography, and LA active emptying fraction was calculated. The standardized correlation coefficient for the correlation between each factor and LA active emptying fraction was calculated by using univariate and backward multivariable regression analyses. RESULTS: The multivariable regression analysis demonstrated that the heart rate (ß = 0.15; p = 0.001), S (ß = 0.09; p = 0.036), E/e' ratio (ß = -0.11; p = 0.014), left ventricle (LV) ejection fraction (ß = 0.15; p = 0.001), and LA enlargement (ß = -0.19; p < 0.001) were the independent determinants of LA active emptying fraction. CONCLUSIONS: The independent determinants of LA contraction function were the heart rate, S, LV ejection fraction, LA enlargement, and E/e' ratio in candidates for CABG surgery.

Effects of obesity on left atrial phasic functions in patients with chronic ischemic heart disease and preserved left ventricular ejection fraction without recent myocardial infarction: a two-dimensional speckle-tracking echocardiography study.

PURPOSE: Left atrial (LA) phasic functions in various subgroups of subjects with obesity are differently impaired, suggesting that obesity may have diverse effects in dissimilar subgroups of subjects with obesity. We aimed to compare the effects of obesity on LA phasic functions in patients suffering from chronic ischemic heart disease with a preserved left ventricular ejection fraction and without a recent myocardial infarction. METHODS: In our cross-sectional study, 145 consecutive candidates for isolated coronary artery bypass graft (CABG) surgery were divided according to the presence of obesity into 2 groups: obese (36 patients) and nonobese (103 patients), and LA phasic functions were evaluated by two-dimensional speckle-tracking echocardiography (2D STE). RESULTS: The longitudinal strain rate during the reservoir phase (3.0 ± 0.7 s-1 vs 2.7 ± 0.6 s-1; P = 0.032), longitudinal strain during the contraction phase (19.2 ± 4.7% vs 17.2 ± 4.1%; P = 0.022), and the longitudinal strain rate during the contraction phase (4.4 ± 1.2 s-1 vs 3.9 ± 1.2 s-1; P = 0.036) decreased in the obese group compared with the nonobese group. The other longitudinal 2D STE-derived markers of the LA phasic functions were not different between the 2 groups. CONCLUSIONS: Among patients suffering from chronic ischemic heart disease with a preserved left ventricular ejection fraction and without a recent myocardial infarction, LA reservoir and contraction functions as measured by 2D STE were impaired in patients with obesity compared with those without it.

The evaluation of right ventricular function in patients with diabetes mellitus and significant stenosis at the proximal portion of the right coronary artery.

PURPOSE: Previous studies have indicated that right ventricular (RV) function is damaged in diabetes mellitus (DM); however, it is not clear whether in the presence of chronic ischemia, RV function is different between patients with and without DM (DM + and DM - , respectively). METHODS: This cross-sectional study enrolled 90 consecutive candidates for coronary artery bypass graft surgery and allocated them to 3 groups: 24 DM - patients with the absence of stenosis of more than 50% in the proximal and mid parts of the right coronary artery (the DM - RCA - group [control]), 33 DM - patients with the presence of significant stenosis (> 70%) in the proximal part of RCA (the DM - RCA + group), and 33 DM + patients with RCA + (the DM + RCA + group). RV function was evaluated based on longitudinal deformation markers, measured via the 2D speckle-tracking echocardiographic examination of right ventricular free wall (RVFW). RESULTS: The systolic strain value, systolic strain rate, and late diastolic strain rate of RVFW were not statistically significantly different between the three groups. Our adjusted post hoc analysis showed that the early diastolic strain rate of RVFW in the DM + RCA + group was lower than that in the DM - RCA + and DM - RCA - groups (1.5 s-1 ± 0.4 vs 1.7 s-1 ± 0.5 vs 1.7 s-1 ± 0.4). CONCLUSIONS: Diastolic function in the presence of DM was impaired irrespective of RCA - or RCA + . Additionally, RCA + had no effect on systolic and diastolic RV functions at rest in our DM - patients.

Case report: Multimodal imaging diagnosis of a giant coronary artery fistula: A report of two cases.

Being a very rare cardiac disease, most cases of coronary artery fistula (CAF) are genetic. Complications such as coronary steal syndrome, myocardial infarction, heart failure, or tamponade can manifest following the abnormal communication that the fistula creates between the coronary arteries and cardiac chambers or major vessels and the subsequent shunt. Most CAFs are small and asymptomatic, making diagnosis difficult. In symptomatic patients, the initial diagnostic workup is generally made with chest radiography and electrocardiography. Other imaging modalities have also been suggested to improve diagnostic accuracy. Cardiac catheterization and coronary angiography are currently the gold standard for diagnosis and planning the intervention, as they can recognize the quantum of the shunt as well as complications of a fistulous track (e.g., aneurysm formation, thrombus, leak, and the number of openings to the receiving chamber/vessel); however, this invasive method may be associated with risk. Herein, we report two patients with giant CAFs, one from the left circumflex artery to the coronary sinus and the other to the superior vena cava. Moreover, we describe how multimodal imaging, including two- and three-dimensional transesophageal echocardiography, coronary cineangiography, coronary computed tomography angiography, and enhanced chest computed tomography, can facilitate diagnosis and estimate the disease course in such patients. We believe that using multimodal imaging cannot only help the initial diagnosis regarding the presence of a CAF and the accurate anatomical site of the fistula in the patient but can also help predict the disease course and choose the most suitable treatment modality. Therefore, we suggest multimodal imaging be done to diagnose patients suspected of CAF. However, invasive cineangiography should be necessarily followed, regardless of whether an intervention is planned or not.

A systematic review and meta-analysis of the normal reference value of the longitudinal left atrial strain by three dimensional speckle tracking echocardiography.

The normal reference value of the global longitudinal left atrial strain during the reservoir phase (LASr) by 3D speckle-tracking echocardiography (3DSTE) is needed to define the abnormal and normal spectra and to compare and interpret the obtained values. The present study is a meta-analysis of 3DSTE-derived normal reference value of the longitudinal LASr and an attempt to determine probable contributing factors in the variations of reported ranges. The databases of PubMed, Scopus, and Embase were searched for the following keywordS: "Left atrial/left atrium" and "strain/speckle/deformation" and "three-dimensional/3-dimensional/three dimensional/3 dimensional/three dimension/3 dimension/three-dimension/3-dimension/3D/3-D". The studies selected included those on adult healthy subjects without cardiovascular risk factors. A random-effect model was used to calculate the global 3DSTE-derived longitudinal LASr, and meta-regression was applied to determine inter-study heterogeneity. Our search yielded 316 adult subjects from 5 studies. The mean value of the global 3DSTE-derived longitudinal LASr was 27.5% (95% CI, 25.2-29.8%). There was significant heterogeneity between the studies. The meta-regression analysis revealed the publication year, the heart rate, and systolic and diastolic blood pressure as the sources of heterogeneity. The current meta-analysis determined a normal reference value of the global 3DSTE-derived longitudinal LASr of 27.5% (95% CI, 25.2-29.8%). The heterogeneity between studies may be explained by the publication year, the heart rate, and systolic and diastolic blood pressure.

Latent Avulsion of the Posterior Mitral Leaflet Base from the Mitral Annulus Following a Motor Vehicle Accident: A Case Report.

Injuries to the heart and great vessels should always be considered after blunt chest trauma. Valvular damage rarely occurs after blunt trauma, but symptoms may be delayed. A 58-year-old woman was referred to our hospital with exertional dyspnea (functional class III) and palpitations for elective transesophageal echocardiography. Her symptoms had exacerbated in the preceding 2 or 3 months. Physical examination showed holosystolic murmurs (IV/VI) at the lower sternal border with extension to the apex. Transesophageal echocardiography revealed avulsion of the base of the posterior mitral valve leaflet (P3) from the annulus. In the past medical history, there was a history of a motor vehicle accident 9 months earlier. The patient was recommended for mitral valve surgery. Mitral valve replacement was performed, and the diagnosis was confirmed by surgery. The patient was discharged without any complications.
