Objectives: Aims of this study were: 1) to evaluate feasibility of RT-3D echocardiography for LA evaluation in an acute care setting and in a population including a majority of critically ills; 2) to evaluate correlation between two-dimensional (2D) and RT-3D echocardiographic LA quantitative evaluation; 3) to assess clinical consistency and prognostic value of LA measurements obtained from RT-3D images in subjects without CV diseases and in patients with AF and CHF, evaluated in the acute phase of the disease. Patients and Methods: In 382 subjects admitted in the emergency department (ED), we evaluated maximal (Volmax) and minimal (Volmin) LA volumes and LA emptying fraction (LA-EF), from RT-3D images, with a semiautomated border detection program. A follow-up was performed in order to evaluate all-cause mortality and new hospital admission for cardiovascular events. Results: The correlation between measures obtained from 2D and 3D was good (LA Volmax: r = 0.896, P < 0.001; Volmin: r = 0.906, P < 0,001; LA EF: r = 0.749, P < 0.001). Among 77 normal subjects, people aged ≥ 65 years demonstrated comparable LA dimensions with younger subjects (LA Volmax: 25 ± 11 vs 20 ± 7 mL/m2, Volmin: 11 ± 7 vs 8 ± 5 mL/m2). Subjects with normal left ventricular ejection fraction showed LA Volmax significantly lower than patients with LV systolic dysfunction or congestive heart failure (23 ± 11 vs 29 ± 10 vs 33 ± 12 mL/m2, P < 0.05). Patients in atrial fibrillation showed a significantly dilated LA compared with subjects in sinus rhytm (24 ± 11 vs 37 ± 22 mL/m2, P < 0.05). LA dimensions were significantly higher in non-survivors (LA Volmax: 33 ± 9 vs 25 ± 9 mL/m2), in patients with a new hospital admission for cardiovascular disease (LA Volmax: 34 ± 13 vs 23 ± 10 mL/m2) or with a new AF episode (LA Volmax: 40 ± 12 vs 24 ± 11 mL/m2, all P < 0.005). Conclusions: RT-3D evaluation of LA volumes and function is feasible in a non selected series of critically ills. LA dilation was associated with a worse outcome in terms of morbidity and mortality.","PeriodicalId":429543,"journal":{"name":"Archives of Cardiovascular Imaging","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121185745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, mortality still remains elevated. This is a case of acute papillary muscle rupture secondary to myocardial infarction leading to cardiogenic shock. Case Presentation: A 71-year-old woman presented to an outside hospital complaining of chest pain and shortness of breath. An electrocardiogram was obtained and revealed depression of the ST segments from leads V1 to V4. Troponin I was elevated at 3.0 ng/mL. She was transferred to our facility for a higher level of care. She was found in cardiogenic shock at arrival. A bedside echocardiogram was ordered, which demonstrated papillary muscle rupture with severe mitral regurgitation. A coronary angiogram followed, which diagnosed severe three-vessel disease. After the insertion of an intra-aortic balloon pump, she was transferred emergently to the surgical suite for mitral valve replacement and revascularization. The operation was uneventful. She was discharged to a rehabilitation center after approximately 1 month of hospital stay. Conclusions: Mortality from papillary muscle rupture remains elevated. Survival largely depends on the early surgical repair or the replacement of the mitral valve.","PeriodicalId":429543,"journal":{"name":"Archives of Cardiovascular Imaging","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125403157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wiwanitkit","doi":"10.5812/ACVI.33506","DOIUrl":"https://doi.org/10.5812/ACVI.33506","url":null,"abstract":"Thalassemia is an important congenital hereditary disorder that is highly endemic in Southeast Asia (1). Patients with thalassemia usually suffer from fragile red blood cells and severe anemia. Blood transfusion is usually required, and long-term transfusion can result in excessive iron accumulation in several organs including the cardiovascular system (2). The cardiovascular problem in patients with thalassemia is an intriguing issue. However, there are only a few reports on cardiovascular imaging among thalassemic patients. According to Peng et al. (3) iron cardiomyopathy is a significant problem in thalassemic patients; magnetic resonance imaging and echocardiography can be used to assess such patients but reliability is the major problem. Nevertheless, it is hard to access advanced imaging technology in real clinical practice given that many patients live in poor settings such as rural communities in Southeast Asia, South Asia, and South America. Based on PubMed search, there are few reports on cardiovascular imaging in thalassemia. Magnetic resonance T2 * imaging is reported in some publications. Djer et al. (4) reported an observation on the correlation between T2 * cardiovascular magnetic resonance (CMR) and left ventricular function and mass in adolescent and adult major thalassemia patients with iron overload and concluded that myocardial conduction time by T2 * CMR has a moderate positive correlation with diastolic function and moderate negative correlation with serum ferritin, but not with left ventricular mass index and systolic function. A study conducted by He (5) concluded that magnetic resonance T2 * imaging is useful for the assessment of iron overload among thalassemic patients. Indubitably, imaging modalities can be useful in the diagnosis of cardiac pathology due to iron overload. Nonetheless, the question remains as to its effectiveness in the follow-up of such patients. Recently, Baksi and Pennell (6) reported that the use of magnetic resonance T2 * imaging might be limited at follow-up. Additionally, Akcay et al. (7) reported no relationship between magnetic resonance T2* imaging and the markers used in the follow-up of patients with thalassemia. Cardiovascular imaging in patients with thalassemia can be fertile ground for further research in cardiovascular imaging medicine.","PeriodicalId":429543,"journal":{"name":"Archives of Cardiovascular Imaging","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128638187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: Our aim was to study the relation between VAC and the parameters of myocardial mechanics using three-dimensional speckle-tracking echocardiography (3DSTE). Patients and Methods: We studied 68 normal participants (mean age, 35 ± 12.2 y; 36 [53%] males). VAC was measured by the ratio of arterial elastance (Ea) to ventricular elastance (Ees). The peak systolic value of longitudinal strain (LS), circumferential strain (CS), radial strain, three-dimensional global strain (3DGS), apical rotation, torsion, and twist and their time to peak were calculated. Results: Almost all deformation indices were higher in the women than in the men. LS (r = -0.41, P < 0.01), twist (r = 0.26, P < 0.03), rotation (r = 0.41, P < 0.01), and 3DGS (r = - 0.39, P < 0.01) were associated with age. Although significant associations were found between VAC and Ea or Ees in the men and women, no relation was found between Ea and Ees in both sexes (r = 0.07 in men and r = 0.08 in women). Indeed, VAC had a stronger association with Ea than with Ees (r = 0.708 vs. r = -0.537). Ees and VAC were related to torsion (r = 0.30 vs. r = -0.37; both P < 0.05); and Ea, Ees, and VAC were also associated with CS (r = 0.64, r = -0.45, and r = 0.79; all P < 0.05) and 3DGS (r = -0.55, r = 0.38, and r = -0.64; all P < 0.01).

The cardiac involvement could be silent. Echocardiography can be used as a noninvasive tool for the assessment of the ventricular function. Objectives: We sought to evaluate different echocardiographic parameters via tissue Doppler imaging and speckle-tracking echocardiography (STE) in addition to conventional echocardiography. Patients and Methods: This case-control study was conducted in 45 SLE patients (88% female; mean age = 31.2 ± 8.2 years) and 25 healthy controls (87% female; mean age = 30.3 ± 7.7 years), matched in terms of age and sex. Both groups had no clinical signs and symptoms of cardiac problems or risk factors for cardiovascular diseases. Both SLE and control groups underwent echocardiography for the assessment of the ventricular function and the sizes and diameters of the chambers. Two-dimensional STE was used for the measurement of the left ventricular (LV) global longitudinal systolic strain. Results: The mean duration of SLE was 5.5 ± 3.4 years in our patients. No significant difference was found between the two groups concerning the LV and left atrium size, LV ejection fraction, right ventricular (RV) systolic function, RV and LV diastolic function, and pulmonary artery pressure. The LV global longitudinal strain was less in the SLE patients (-18.56 ± 2.50% vs. -19.89 ± 1.94%; P = 0.028). The LV mass was greater, though not statistically significant, in the SLE patients (111 ± 29.54 g vs. 104.37 ± 27.39 g; P = 0.468). The interventricular septal diameter was thicker in the SLE patients (0.79 ± 0.15 cm vs. 0.77 ± 0.10 cm; P = 0.046). Conclusions: Silent ventricular systolic dysfunction was more common in the patients with SLE than in the control group. Newer echocardiographic techniques such as two-dimensional STE provide an earlier chance for the detection of subclinical LV systolic dysfunction. Our findings were independent of the traditional risk factors.","PeriodicalId":429543,"journal":{"name":"Archives of Cardiovascular Imaging","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132855430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: We compared coronary-artery delineation between AMC and conventional CCTA reconstruction (CR). Patients and Methods: CCTA images (clinical single-source-64-slice-CT system) of 17 consecutive patients with heart rates exceeding 55 bpm were reconstructed with both CR and AMC during the individually best-suited phase of the cardiac cycle. Two independent readers who were blinded to the reconstruction algorithm scored image quality of each coronary artery segment (AHA 15-segment-model; 1: non-diagnostic - 4: excellent). In case of disagreement a third blinded reader assigned a final score. Two-tailed statistical tests (Wilcoxon-matched-pairs, Pearson-correlation) were significant at P < 0.05. Results: Mean heart rate during CCTA was 61 ± 8 bpm. CCTA quality improved significantly in the RCA (good-or-excellent in 11/17 AMC vs. 5/17 CR, P = 0.018) and LAD (15/17 vs. 7/17, P = 0.031). Non-diagnostic CCTA in the RCA, LM, LAD, and LCX reduced from 16/68 (CR, 24%) to 7/68 (AMC, 10%). Significant motion correction was observed at low (≤ 60 bpm; P = 0.008), intermediate (61-70 bpm; P < 0.001), and high heart rates (> 70 bpm; P = 0.021). Inter-reader agreement was good.
