RESUMEN

BACKGROUND: People with human immunodeficiency virus (HIV) have been reported to have increased risk of clinical and subclinical cardiovascular disease. Existing studies have focused on men and often have been uncontrolled or lacked adequate HIV-negative comparators. METHODS: We performed echocardiography in the Women's Interagency HIV Study to investigate associations of HIV and HIV-specific factors with cardiac phenotypes, including left ventricular systolic dysfunction (LVSD), isolated LV diastolic dysfunction (LVDD), left atrial enlargement (LAE), LV hypertrophy (LVH), and increased tricuspid regurgitation velocity (TRV). RESULTS: Of 1654 participants (age 51 ± 9 years), 70% had HIV. Sixty-three (5.4%) women with HIV (WWH) had LVSD; 71 (6.5%) had isolated LVDD. Compared with women without HIV (WWOH), WWH had a near-significantly increased risk of LVSD (adjusted relative risk = 1.69; 95% confidence interval = 1.00 to 2.86; P = .051). No significant association was noted for HIV seropositivity with other phenotypes, but there was a risk gradient for decreasing CD4+ count among WWH that approached or reached significance for isolated LVDD, LAE, and LVH. WWH with CD4+ count <200 cells/mm3 had significantly higher prevalence of LAE, LVH, and high TRV than WWOH. There were no consistent associations for viral suppression or antiretroviral drug exposure. CONCLUSIONS: This study suggests that WWH have a higher risk of LVSD compared with sociodemographically similar WWOH, but their risk for isolated LVDD, LAE, LVH, and high TRV is increased only with reduced CD4+ count. Although these findings warrant replication, they support the importance of cardiovascular risk-factor and HIV-disease control for heart disease prevention in this population.

RESUMEN

BACKGROUND: Whether the combination of ventricular strain with high-sensitivity troponin I (hs-TNI) has an incremental prognostic value in coronavirus disease 2019 (COVID-19) patients has not been evaluated. The study aimed to evaluate the prognostic value of biventricular longitudinal strain and its combination with hs-TNI in COVID-19 patients. METHODS: A total of 160 COVID-19 patients who underwent both echocardiography and hs-TNI testing were enrolled in our study. COVID-19 patients were divided into two groups (critical and non-critical) according to severity-of-illness. The clinical characteristics, cardiac structure and function were compared between the two groups. The prognostic value of biventricular longitudinal strain and its combination with hs-TNI were evaluated by logistic regression analyses and receiver operating characteristic curves. Left ventricular longitudinal strain (LV LS) and right ventricular free wall longitudinal strain (RVFWLS) were determined by 2D speckle-tracking echocardiography. RESULTS: The LV LS and RVFWLS both were significantly lower in critical patients than non-critical patients (LV LS: -16.6±2.4 vs -17.9±3.0, P = .003; RVFWLS :-18.8±3.6 vs -23.9±4.4, P<.001). During a median follow-up of 60 days, 23 (14.4%) patients died. The multivariant analysis revealed that LV LS and RVFWLS [Odd ratio (95% confidence interval): 1.533 (1.131-2.079), P = .006; 1.267 (1.036-1.551), P = .021, respectively] were the independent predictors of higher mortality. Further, receiver-operating characteristic analysis revealed that the accuracy for predicting death was greater for the combination of hs-TNI levels with LV LS than separate LV LS (AUC: .91 vs .77, P = .001), and the combination of hs-TNI levels with RVFWLS than RVFWLS alone (AUC: .89 vs .83, P = .041). CONCLUSIONS: Our study highlights that the combination of ventricular longitudinal strain with hs-TNI can provide higher accuracy for predicting mortality in COVID-19 patients, which may enhance risk stratification in COVID-19 patients.

RESUMEN

We present a late presentation of saddle pulmonary embolism and thrombus-in-transit straddle the patent foramen on patient who successfully recovered from severe acute respiratory syndrome coronavirus-2 (COVID-19) pneumonia. Seven days postdischarge (ie, 28 days after initial COVID-19 symptom onset), she was readmitted to hospital for severe dyspnea. Computer tomography angiogram and echocardiography confirmed the diagnosis. Severe pro-inflammatory and pro-thrombotic states with endothelial involvement have been reported associated with severe COVID-19 infection. However, the duration of hypercoagulable state has not yet known. This case highlights the risk of thromboembolic phenomena for prolonged periods of times after recovering from COVID-19 pneumonia.

RESUMEN

A 34-year-old Hispanic man sustained a stab wound to his chest complicated with hemopericardium and pericardial tamponade. He underwent emergent clamshell thoracotomy as well as repair to the pulmonary artery. A transthoracic echocardiogram showed no evidence of intracardiac shunt. Two months later, a new murmur was noted, with a transthoracic echocardiogram revealing high-velocity flow between the left coronary sinus and the main pulmonary artery, with which a coronary computed tomography angiogram concurred. A transesophageal echocardiogram was performed which revealed an aortopulmonic fistula from the left coronary sinus of Valsalva, approximately 1cm anterior to the ostium of the left main coronary artery, to the main pulmonary artery just distal to the pulmonic valve. Pulmonary insufficiency was minimal. The main pulmonary artery was dilated, measuring 3.2 cm by coronary computed tomography angiogram. Right ventricular systolic function was normal. Right and left heart catheterizations were performed to further assess hemodynamics and coronary anatomy; pulmonary artery pressures were 16/8 mm Hg. Aortopulmonary fistula was seen on aortogram. Surgery was deferred in view of lack of symptoms and uncertainty in its natural history in the setting of traumatic etiology. A repeat transthoracic echocardiogram at six-month follow-up showed spontaneous closure of the fistula.

RESUMEN

Cardiac disease in pregnancy is the number one indirect cause of maternal mortality in the United States. We propose a triad solution that includes universal screening for cardiovascular disease in pregnancy and postpartum women, patient education, and institution of a multidisciplinary cardiac team. Additionally, we emphasize essential elements to maximize care for the pregnant cardiac patient based on our experience at our institution in Bronx, NY.

RESUMEN

BACKGROUND: Left ventricular diastolic dysfunction has been shown to associate with increased risk of atrial fibrillation (AF). We aimed to examine the predictors of AF in individuals with preclinical diastolic dysfunction (PDD) - diastolic dysfunction without clinical heart failure - and develop a risk score in this population. METHODS: Patients underwent echocardiogram from December 2009 to December 2015 showing left ventricular ejection fraction (LVEF) ≥ 50% and grade 1 diastolic dysfunction, without clinical heart failure, valvular heart disease or AF were included. Outcome was defined as new onset AF. Cumulative probabilities were estimated and multivariable adjusted competing-risks regression analysis was performed to examine predictors of incident AF. A predictive score model was constructed. RESULTS: A total of 9591 PDD patients (mean age 66, 41% men) of racial/ethnical diversity were included in the study. During a median follow-up of 54 months, 455 (4.7%) patients developed AF. Independent predictors of AF included advanced age, male sex, race, hypertension, diabetes, and peripheral artery disease. A risk score including these factors showed a Wolber's concordance index of 0.65 (0.63-0.68, p <  0.001), suggesting a good discrimination. CONCLUSIONS: Our study revealed a set of predictors of AF in PDD patients. A simple risk score predicting AF in PDD was developed and internally validated. The scoring system could help clinical risk stratification, which may lead to prevention and early treatment strategies.

RESUMEN

PURPOSE: The left ventricle (LV) undergoes physiologic remodeling in adaptation to the hemodynamic changes that occur in pregnancy. Speckle tracking echocardiography (STE) is a novel and reliable tool to evaluate subtle myocardial alterations that have been utilized to assess myocardial changes in patients with diabetes mellitus (DM) but not in patients with gestational DM (GDM). We seek to evaluate changes in LV function using STE in patients with GDM compared with women with normal pregnancy. METHODS: This was a single-center retrospective cohort study. A total of 312 pregnant patients that underwent transthoracic echocardiogram (TTE) between 2009 and 2014 were screened. After excluding patients with comorbidities or insufficient data, 90 women were included. TTE from the second and third trimester for each patient were then reviewed, and STE analysis was performed. RESULTS: Of the 90 subjects, 72 had normal pregnancies and 18 developed GDM. There was no difference in LV end-diastolic diameter (4.73 ± 0.40 versus 4.60 ± 0.56, p = 0.25), LV end-systolic diameter (3.12 ± 0.35 versus 2.91 ± 0.61, p = 0.152), or ejection fraction (62.26 ± 4.12 versus 63.50 ± 5.24, p = 0.314) between the two groups. Global longitudinal strain was lower (-19.8 ± 3.34 versus -17.2 ± 2.18, p < 0.001) in patients with GDM, while time-to-peak strain was greater (0.43 ± 0.05 versus 0.50 ± 0.06, p < 0.001). Circumferential and radial strains were preserved in both groups. CONCLUSIONS: Although conventional TTE variables show preserved LV size and function, LV longitudinal strain suggests subclinical myocardial dysfunction in patients with GDM. © 2016 Wiley Periodicals, Inc.

RESUMEN

PURPOSE: Left atrial appendage (LAA) flow velocity has not been extensively studied in patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI). The aim of this study was to assess the impact of TAVI on LAA flow velocity. METHODS: Medical records of consecutive TAVI recipients were reviewed retrospectively. Patients with persistent atrial fibrillation were excluded. LAA velocities were measured before and after TAVI by transesophageal echocardiography. RESULTS: Sixty-one patients were included. Mean LAA emptying (EV) and filling (FV) flow velocity before TAVI were 33 ± 16 cm/s and 31 ± 14 cm/s, respectively. They increased to 37 ± 20 (p = 0.0036) and 33 ± 13 cm/s (p = 0.047) after TAVI in the whole population sample, but not in patients with normal flow AS. In low-flow, low-gradient (LFLG) AS patients, EV and FV increased from 36 ± 22 to 47 ± 30 cm/s (p < 0.01), and from 29 ± 12 to 40 ± 15 cm/s (p < 0.01), respectively, after TAVI. There was no difference between normal flow and LFLG AS patients in the number of patients who achieved EV ≥ 40 cm/s post-TAVI (35% versus 47%, p = 0.54, respectively). CONCLUSIONS: LAA EV and FV were low prior to TAVI and increased significantly after TAVI only in patients with LFLG AS. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound 44:375-382, 2016.

RESUMEN

BACKGROUND: Ventricular septal defects (VSD) are rarely reported as a complication following transcatheter aortic valve replacement (TAVR). We sought to characterise the patients, clinical management, and outcomes regarding this rare phenomenon. METHODS: Relevant articles were identified by a systematic search of MEDLINE and EMBASE databases from January, 2002 to September, 2015. RESULTS: A total of 18 case reports, including 20 patients, were identified. The median age was 83 years and six were male. Twelve were performed by trans-femoral approach. Pre-dilation was performed in 12 patients and post-dilation in four. Balloon expandable valves were used in the majority (85%) of cases. The clinical presentation varied from asymptomatic to progressive heart failure. The timing of the diagnosis also varied significantly from immediately post valve implantation to one year afterwards. There were two cases of Gerbode-type defect while the rest were inter-ventricular defects. The location was mostly membranous or perimembranous (79%) and adjacent to the valve landing zone. A total of seven interventions (one open surgery and six percutaneous closure) were performed. Four patients died during the same hospital admission. Sixteen survived past discharge (range 12 days to two years). CONCLUSIONS: Ventricular septal defects post-TAVR were seen more with balloon expandable valves and with pre-dilation or post-dilation. Percutaneous treatment of the VSD was preferred over open cardiac surgery given the high surgical risk in this patient population. Some, but not all, patients survived TAVR and VSD and had a good prognosis for both patient groups with or without VSD closure.

RESUMEN

BACKGROUND: Pericardial effusion (PE) volume is often assessed semiqualitatively by echocardiography and categorized into minimal, small, moderate, or large. Several methods of echocardiographic quantification have been proposed, but their application is limited either by complexity or inaccuracy. We evaluated the accuracy of PE volume quantification by two-dimensional transthoracic echocardiogram (2DTTE) and commercially available volume quantification software in patients undergoing pericardiocentesis. METHODS: In a retrospective case series, immediate preprocedure echocardiograms of 33 patients for pericardiocentesis were analyzed. 2DTTE using the Simpson's method was adopted for volume measurement in the apical two- and four-chamber views. Pericardial fluid volume was calculated by taking the difference between volumes obtained by tracing the epicardial border of the heart and the pericardium. Postprocedure echocardiograms were performed to verify adequate pericardiocentesis. RESULTS: The mean pericardiocentesis fluid volume was 725.1 ± 299.5 mL (range, 250-1420 mL). The average volume estimated echocardiographically by the Simpson's method was 657.5 ± 276.9 mL (range, 205.7-1193.2 mL). There was strong direct linear correlation between echocardiographic and pericardiocentesis-derived volumes (P < 0.001, r = +0.823). Echocardiography underestimated PE volume by a mean of 9.3%. CONCLUSION: Two-dimensional transthoracic echocardiography using biplane Simpson's method of disks can simply and accurately estimate PE volume.

RESUMEN

BACKGROUND: Comparative effectiveness research (CER) has become a major focus of cardiovascular disease investigation to optimize diagnosis and treatment paradigms and decrease healthcare expenditures. Acute chest pain is a highly prevalent reason for evaluation in the Emergency Department (ED) that results in hospital admission for many patients and excess expense. Improvement in noninvasive diagnostic algorithms can potentially reduce unnecessary admissions. OBJECTIVE: To compare the performance of treadmill stress echocardiography (SE) and coronary computed tomography angiography (CTA) in ED chest pain patients with low-to-intermediate risk of significant coronary artery disease. DESIGN: This is a single-center, randomized controlled trial (RCT) comparing SE and CTA head-to-head as the initial noninvasive imaging modality. The primary outcome measured is the incidence of hospitalization. The study is powered to detect a reduction in admissions from 28% to 15% with a sample size of 400. Secondary outcomes include length of stay in the ED/hospital and estimated cost of care. Safety outcomes include subsequent visits to the ED and hospitalizations, as well as major adverse cardiovascular events at 30 days and 1 year. Patients who do not meet study criteria or do not consent for randomization are offered entry into an observational registry. CONCLUSIONS: This RCT will add to our understanding of the roles of different imaging modalities in triaging patients with suspected angina. It will increase the CER evidence base comparing SE and CTA and provide insight into potential benefits and limitations of appropriate use of treadmill SE in the ED.

RESUMEN

A major manifestation of Friedreich ataxia (FRDA) is cardiomyopathy, caused by mitochondrial proliferation in myocytes. Because the lifespan for patients with FRDA improves with better treatment modalities, more patients are becoming pregnant, meaning that more medical providers must know how to care for this population. This report provides a review of the literature on multidisciplinary management of pregnant patients with FRDA and cardiomyopathy from preconception through lactation. A cardio-obstetrics team, including cardiology, anesthesiology, and obstetrics, should be involved for this entire period. All patients should be counseled on pregnancy risk using elements of existing stratification systems, and contraception should be discussed, highlighting the safety of intrauterine devices. Electrocardiogram should be obtained at baseline and each trimester, looking for atrial arrhythmias and ST-segment changes, as should transthoracic echocardiogram, with a focus on left ventricular ejection fraction-which is typically normal in FRDA cardiomyopathy-and relative wall thickness and global longitudinal strain-which tend to decrease as cardiomyopathy progresses. Brain natriuretic peptide is also a helpful marker to detect adverse events. If heart failure develops, it should be treated like any other etiology of heart failure during pregnancy. Atrial arrhythmias should be treated with ß blockers or electrical cardioversion and anticoagulation, as necessary. Most patients with FRDA can deliver vaginally, and neuraxial analgesia is recommended during labor because of the risks associated with general anesthesia. Breastfeeding is encouraged, even for those taking cardiac medications.

RESUMEN

BACKGROUND: Left bundle branch block (LBBB) represents a frequently encountered conduction system disorder. Despite its widespread occurrence, a continual dilemma persists regarding its intricate association with underlying cardiomyopathy and its pivotal role in the initiation of dilated cardiomyopathy. The pathologic alterations linked to LBBB-induced cardiomyopathy (LBBB-CM) have remained elusive. OBJECTIVE: This study sought to investigate the chronologic dynamics of LBBB to left ventricular dysfunction and the pathologic mechanism of LBBB-CM. METHODS: LBBB model was established through main left bundle branch trunk ablation in 14 canines. All LBBB dogs underwent transesophageal echocardiography and electrocardiography before ablation and at 1 month, 3 months, 6 months, and 12 months after LBBB induction. Single-photon emission computed tomography imaging was performed at 12 months. We then harvested the heart from all LBBB dogs and 14 healthy adult dogs as normal controls for anatomic observation, Purkinje fiber staining, histologic staining, and connexin43 protein expression quantitation. RESULTS: LBBB induction caused significant fibrotic changes in the endocardium and mid-myocardium. Purkinje fibers exhibited fatty degeneration, vacuolization, and fibrosis along with downregulated connexin43 protein expression. During a 12-month follow-up, left ventricular dysfunction progressively worsened, peaking at the end of the observation period. The association between myocardial dysfunction, hypoperfusion, and fibrosis was observed in the LBBB-afflicted canines. CONCLUSION: LBBB may lead to profound myocardial injury beyond its conduction impairment effects. The temporal progression of left ventricular dysfunction and the pathologic alterations observed shed light on the complex relationship between LBBB and cardiomyopathy. These findings offer insights into potential mechanisms and clinical implications of LBBB-CM.

RESUMEN

Purpose: To evaluate the safety, efficacy, and outcomes of outpatient intravenous diuresis in a rural setting and compare it to urban outcomes. Methods: A single-center study was conducted on 60 patients (131 visits) at the Dartmouth-Hitchcock Medical Center (DHMC) from 1/2021-12/2022. Demographics, visit data, and outcomes were collected and compared to urban outpatient IV centers, and inpatient HF hospitalizations from DHMC FY21 and national means. Descriptive statistics, T-tests and chi-squares were used. Results: The mean age was 70 ± 13 years, 58% were male, and 83% were NYHA III-IV. Post-diuresis, 5% had mild-moderate hypokalemia, 16% had mild worsening of renal function, and 3% had severe worsening of renal function. No hospitalizations occurred due to adverse events. The mean infusion-visit urine output was 761 ± 521 ml, and post-visit weight loss was -3.9 ± 5.0 kg. No significant differences were observed between HFpEF and HFrEF groups. 30-day readmissions were similar to urban outpatient IV centers, DHMC FY21, and the national mean (23.3% vs. 23.5% vs. 22.2% vs. 22.6%, respectively; p = 0.949). 30-day mortality was similar to urban outpatient IV centers but lower than DHMC FY21 and the national means (1.7% vs. 2.5% vs. 12.3% vs. 10.7%, respectively; p < 0.001). At 60 days, 42% of patients had ≥1 clinic revisit, 41% had ≥1 infusion revisit, 33% were readmitted to the hospital, and two deaths occurred. The clinic avoided 21 hospitalizations, resulting in estimated cost savings of $426,111. Conclusion: OP IV diuresis appears safe and effective for rural HF patients, potentially decreasing mortality rates and healthcare expenses while mitigating rural-urban disparities.

RESUMEN

OBJECTIVE: Echocardiography-guided Percutaneous IntraMyocardial Septal Radiofrequency Ablation (PIMSRA, Liwen procedure) is a novel treatment option for hypertrophic obstructive cardiomyopathy (HOCM). The impact of PIMSRA on myocardial mechanics is unknown. METHODS: Between October 2016 and June 2019, PIMSRA and 3-dimentional speckle tracking echocardiography were performed in 82 patients. Echocardiographic imaging, qualitative and quantitative clinical assessment were completed at baseline, immediately postprocedure and 1-year follow-up. RESULTS: There was a significant reduction in the peak left ventricular outflow tract (LVOT) gradients immediately following PIMSRA and at 1-year follow-up (resting gradients: from 83.50 (61.25) to 23.00 (41.75) mm Hg, p<0.001 and 13.50 (21.75) mm Hg, p<0.001, respectively; stress-induced gradients: from 118.25 (96.02) to 47.00 (74.50) mm Hg (1 year), p<0.001). There was an improvement in exercise time on stress echocardiography (p<0.001) and distance by 6 min walk test (p=0.034). Immediately after PIMSRA, there was a significant reduction in radial and circumferential strain in the ablated segments (p<0.001), with no change of longitudinal strain. At 1-year follow-up, the radial and circumferential strain recovered in the ablated segments. Meanwhile, left ventricular regional and global longitudinal strain had improved significantly (p<0.05). CONCLUSIONS: PIMSRA is an effective treatment for symptomatic HOCM that resulted in a sustained improvement in exercise capacity, a persistent decrease in LVOT gradient, and a measurable increase in myocardial contractile function.

RESUMEN

Point-of-care ultrasonography (POCUS) refers to limited bedside ultrasound used to evaluate patients for conditions specific to the scope of their practice. Given the benefits of its application, interest in its use is increasing. We aimed to review the literature and assess the potential feasibility of using POCUS of the heart and lungs in the field of obstetrics. We aim to describe its relevance and value as an adjunctive tool for critically ill obstetric patients on labor and delivery wards.

RESUMEN

Objective: We aim to explore patterns of inpatient code status during the COVID-19 pandemic compared with a similar timeframe the previous year, as well as utilization of palliative care services.Methods: This is a retrospective cohort study using data from the Montefiore Health system of all inpatient admissions between March 15-May 31, 2019 and March 15-May 31, 2020. Univariate logistic regression was performed with full code status as the outcome. All statistically significant variables were included in the multivariable logistic regression.Results: The total number of admissions declined during the pandemic (16844 vs 11637). A lower proportion of patients had full code status during the pandemic (85.1% vs 94%, P < .001) at the time of discharge/death. There was a 20% relative increase in the number of palliative care consultations during the pandemic (12.2% vs 10.5%, P < .001). Intubated patients were less often full code (66.5% vs 82.2%, P < .001) during the pandemic. Although a lower portion of COVID-19 positive patients had a full code status compared with non-COVID patients (77.6% vs 92.4%, P<.001), there was no statistically significant difference in code status at death (38.3% vs 38.3%, P = .96).Conclusions: The proportion of full code patients was significantly lower during the pandemic. Age and COVID status were the key determinants of code status during the pandemic. There was a higher demand for palliative care services during the pandemic.

RESUMEN

BACKGROUND: Limited evidence-based therapies exist for the management of heart failure with preserved ejection fraction (HFpEF). Sodium-glucose cotransporter-2 inhibitor (SGLT2i) use in patients with systolic heart failure (HFrEF) and type-2-diabetes mellitus (T2DM) is associated with improved cardiovascular (CV) and renal outcomes. OBJECTIVE: We sought to examine whether there is an association of SGLT2i use with improved CV outcomes in patients with HFpEF. PATIENTS AND METHODS: We conducted a single-center, retrospective review of patients with HFpEF and T2DM. The cohort was divided into two groups based on prescription of a SGLT2i or sitagliptin. The primary outcome was heart failure hospitalization (HFH); secondary outcomes were all-cause hospitalization and acute kidney injury (AKI). RESULTS: After propensity score matching, there were 250 patients (89 in the SGLT2i group, 161 in the sitagliptin group), with a mean follow-up of 295 days. Univariate Cox regression analysis showed that the SGLT2i group had a reduced risk of HFH versus the sitagliptin group (hazard ratio (HR) 0.13; 95% confidence interval (CI) (0.05-0.36); p < 0.001). The SGLT2i group had a decreased risk of all-cause hospitalization (HR 0.48; 95% CI (0.33-0.70); p < 0.001) and SGLT2i had a lower risk of AKI (HR 0.39; 95% CI (0.20-0.74); p = 0.004). CONCLUSIONS: The use of SGLT2is is associated with a reduced incidence of HFH and AKI in patients with HFpEF and T2DM.
