RESUMO

The landscape of cancer survivorship is increasingly populated by individuals facing a spectrum of cardiometabolic risks, attributed to both their oncological history and treatment regimens. This manuscript synthesizes findings from various studies, highlighting the prevalence of traditional risk factors-hypertension, dyslipidemia, diabetes-as well as emergent concerns like obesity and metabolic syndrome among survivors. The impact of demographic variables, specific cancer types, and treatment modalities on cardiometabolic health is explored. Through a lens of multidisciplinary management and future research directives, we advocate for an integrative approach to cardiometabolic health in cancer survivors, aiming to ensure their victory over cancer extends into long-term well-being.

RESUMO

OBJECTIVE: This systematic review aims to assess the comparative effectiveness and safety of temporary mechanical circulatory support (MCS) devices in various subgroups of patients with acute cardiogenic shock, providing insights for personalized clinical decision-making. METHODS: We conducted a comprehensive search across major databases to identify studies that reported on the use of temporary MCS devices like TandemHeart, Impella, and VA-ECMO in acute cardiogenic shock. Special attention was given to subgroup analyses based on etiologies of shock, patient demographics, and comorbid conditions. RESULTS: Our analysis revealed that while devices like TandemHeart and Impella offer significant hemodynamic support, their effectiveness and safety profiles vary across different patient subgroups. VA-ECMO demonstrated the highest flow rates and potential for mortality benefits but requires careful management due to associated risks. The lack of randomized controlled trials in specific patient subgroups highlights a gap in the current literature, underscoring the need for targeted research. CONCLUSION: The review underscores the necessity of a personalized approach in selecting temporary MCS devices for patients with acute cardiogenic shock, guided by specific patient characteristics and clinical scenarios. Future research should focus on addressing the identified evidence gaps through well-designed studies that provide robust subgroup-specific data, enabling clinicians to optimize treatment strategies and improve patient outcomes in this critical care context.

RESUMO

The management of heart failure has undergone significant evolution, advancing from the initial utilization of digitalis and diuretics to the contemporary practice of personalized medicine and sophisticated device therapy. Despite these advancements, the persistent challenge of high hospitalization and readmission rates underscores an urgent need for innovative solutions. This manuscript explores how the integration of digital health technologies into interventional cardiology marks a paradigm shift in the management of heart failure. These technologies are no longer mere adjuncts but have become foundational to a modern approach, providing tools for continuous monitoring, patient education, and improved outcomes post-intervention. Through an examination of current trends, this perspective article highlights the transformative impact of wearable technologies, telehealth platforms, and advanced analytical tools in reshaping patient engagement and enabling proactive care strategies. Case studies illustrate the practical advantages, including enhanced medication adherence, early detection of heart failure signs, and a reduction in healthcare facility burdens. Central to this new digital health landscape is the Information Technology Management (ITM) system, a framework poised to revolutionize patient and caregiver engagement and pave the way for the future of interventional cardiology. This manuscript delineates the ITM system's innovative architecture and its consequential role in refining current and prospective cardiological interventions.

RESUMO

BACKGROUND: Pulmonary hypertension (PH) poses a significant challenge in the selection of candidates for heart transplantation, impacting their eligibility and post-transplant outcomes. Mechanical circulatory support (MCS) devices, particularly left ventricular assist devices (LVADs), have emerged as a therapeutic option to manage PH in this patient population. This systematic review aims to evaluate the effectiveness of MCS devices in reversing fixed pulmonary hypertension in heart transplant candidates. METHODS: A comprehensive literature search was conducted across multiple databases, including PubMed, Scopus, and Web of Science, to identify studies that evaluated the effectiveness of MCS devices in reversing fixed pulmonary hypertension in heart transplant candidates. Data on pulmonary vascular resistance, PH reversal, heart transplant eligibility, and post-transplant outcomes were extracted and synthesized. RESULTS: The review included studies that demonstrated the potential of MCS devices, especially LVADs, to significantly reduce pulmonary vascular resistance and reverse fixed pulmonary hypertension in heart transplant candidates. These findings suggest that MCS devices can improve transplant eligibility and may positively impact post-transplant survival rates. However, the literature also indicates a need for further comparative studies to optimize MCS device selection and treatment protocols. CONCLUSION: MCS devices, particularly LVADs, play a crucial role in the management of fixed pulmonary hypertension in heart transplant candidates, improving their eligibility for transplantation and potentially enhancing post-transplant outcomes. Future research should focus on comparative effectiveness studies to guide clinical decision-making and optimize patient care in this challenging clinical scenario.

RESUMO

Our case report details the journey of a 16-year-old male patient with Shone complex and advanced heart failure. We highlight the pivotal role of the HeartWare Ventricular Assist Device (Medtronic) implantation in mitigating severe pulmonary hypertension, thereby facilitating his eligibility for a heart transplant. We discuss the subsequent management of post-transplant pulmonary hypertension and right ventricular dysfunction using targeted pulmonary vasodilators and inotropic support, underscoring the intricacies of postoperative care in pediatric heart transplant patients. This case emphasizes our observation of the critical role that left ventricular assist devices play in redefining transplant candidacy and the necessity for complex, ongoing management in pediatric heart transplant scenarios.

RESUMO

BACKGROUND: Pulmonary hypertension (PH) presents as a complex cardiovascular condition with a highly variable prognosis. Secondary tricuspid regurgitation (TR), a frequent comorbidity in PH, has an uncertain impact on patient outcomes. This study investigates the relationship between the severity of TR and mortality in patients with PH. METHODS: A retrospective analysis of 110 PH patients who underwent right-heart catheterization was conducted. TR severity was categorized echocardiographically as mild, moderate, or severe. Both univariate and multivariate Cox regression analyses were used to assess predictors of mortality. RESULTS: The median age of the cohort was 60 years, predominantly female (65 %). Severe TR was present in 36 % of patients. Over a 20-month median follow-up, mortality was notably higher in patients with severe TR (30 %) compared to those with milder forms (15 %, p = 0.04). Multivariate analysis confirmed severe TR, WHO functional class III/IV, and right ventricular stroke work index as independent predictors of mortality. CONCLUSION: Severe TR significantly predicts increased mortality in PH patients, underscoring its importance in patient management. These findings advocate for early detection and comprehensive management of TR, integrating its assessment into routine PH care to potentially enhance patient outcomes.

RESUMO

Spontaneous coronary artery dissection is a serious and underreported clinical entity strongly associated with fibromuscular dysplasia (FMD). The female predominance of FMD may predispose many women to coronary artery dissection or other similar vascular pathologies. We present a case of a young woman who presented with a clinical tetrad of spontaneous coronary artery dissection, cardiogenic shock requiring extracorporeal membrane oxygenation, internal carotid dissections, and subacute cerebellar infarct secondary to underlying FMD. The patient's clinical course and vascular pathology are discussed. A review of the relevant literature of previously published similar cases, the incidence of spontaneous coronary artery dissection, and issues in the clinical management of spontaneous coronary artery dissection are also included.

RESUMO

BACKGROUND: Intermittent high-mechanical index (MI) impulses from a transthoracic ultrasound transducer are recommended for regional wall motion analysis and assessment of myocardial perfusion following intravenous administration of ultrasound enhancing agents (UEAs). High-MI impulses (>1.0) applied in this setting have also been shown to increase microvascular blood flow through a purinergic signaling pathway, but their effects on left ventricular (LV) myocardial function are unknown. Therefore, the aim of this study was to investigate the effect of transthoracic intermittent high-MI impulses during intravenous UEA infusion in patients with normal and abnormal resting systolic function. METHODS: Fifty patients referred for echocardiography to evaluate LV systolic function during continuous infusion of UEAs (Definity 3% infusion) were prospectively assigned to low-MI (<0.2) imaging alone (group 1) or low-MI (<0.2) imaging with intermittent high-MI impulses (five frames, 1.8 MHz, MI = 1.0-1.2) applied at least two times in each apical window to clear myocardial contrast (group 2). Global longitudinal strain (GLS) measurements were obtained at baseline before UEA administration and at 5-min intervals up to 10-min after infusion completion. RESULTS: There were no differences between groups with respect to age, gender, resting GLS, biplane LV ejection fraction, or cardiac risk factors. Resting GLS in group 1 was -15.5 ± 5.2% before UEA infusion and -15.5 ± 5.4% at 10 min after UEA infusion. In comparison, GLS increased in group 2 (-15.3 ± 5.0 before infusion and -16.8 ± 4.8% at 10 min, P < .00001). Improvements in GLS were seen in patients with normal and abnormal systolic function. Regional analysis demonstrated that the increase in strain in patients with abnormal LV ejection fractions was primarily in the apical segments (-12.0 ± 2.7% before infusion and -13.4 ± 3.4% at 10 min, P = .001). CONCLUSIONS: High-MI impulses during infusion of a commercially available contrast agent can improve LV systolic function and may have therapeutic effect in patients with LV dysfunction.

RESUMO

Left ventricular assist device (LVAD) deactivation may be considered in cases of left ventricular recovery, pump thrombosis, infection, and end-of-life palliation. Surgical pump explantation remains the principal method, but percutaneous deactivation presents a safe and effective alternative. We have developed a formal program for percutaneous LVAD deactivation within our advanced heart failure program including patient selection criteria, preprocedure testing, a procedural algorithm, and a postprocedure care plan. Patient selection for percutaneous LVAD deactivation required review by an interdisciplinary heart transplant team including reason for deactivation, cardiac function, surgical risk, and patient preference. All candidates underwent LVAD ramp studies with both transthoracic echocardiography and right heart catheterization assessment. Deactivation was performed under general anesthesia with transesophageal echocardiography guidance. Three Amplatzer Vascular Plug IIs (Abbott, St. Paul, MN) were deployed in the LVAD outflow cannula with the proximal edge of the third plug aligned with the aortic anastomosis of the graft as guided by angiography and 3-dimensional transesophageal echocardiography. In a separate procedure, the LVAD drive line was transected below the skin, which was closed surgically over the driveline stump. Anticoagulation was continued for at least 3 months. Since initiation in January 2017, our program has performed 7 percutaneous LVAD deactivation procedures. All procedures have been successful, 5 of the patients remain medically managed, and 2 have proceeded to heart transplant. Percutaneous LVAD deactivation provides an alternative to surgical explantation. A percutaneous LVAD deactivation program is an important component of an advanced heart failure program.

RESUMO

One of the dreaded complications of left ventricular assist device implantation is mechanical obstruction of the device secondary to pump thrombosis or mechanical outflow cannula obstruction. We describe a case of outflow cannula obstruction caused by kinking and twisting of the outflow graft after surgical manipulation of the pump. (Level of Difficulty: Beginner.).

RESUMO

This is a case of a chronic left ventricular pseudoaneurysm after inferior myocardial infarction that remained clinically silent for 5 years before presenting with sudden rupture, leading to hemopericardium and cardiac tamponade. We discuss the importance of surveillance for left ventricular pseudoaneurysms, the limitations of echocardiography, and the critical role of computed tomography angiography imaging to establish the diagnosis and guide therapy. (Level of Difficulty: Beginner.).

RESUMO

INTRODUCTION: Acute right ventricular myocardial infarction (RVMI) is observed in 30-50% of patients presenting with inferior wall myocardial infarction (MI) and, occasionally, with anterior wall MI. The clinical consequences vary from no hemodynamic compromise to severe hypotension and cardiogenic shock depending on the extent of RV ischemia. Areas covered: The pathophysiological mechanisms, diagnostic steps, and novel therapeutic approaches of acute RVMI are described. Expert commentary: Diagnosis of acute RVMI is based on physical examination, cardiac biomarkers, electrocardiography, and coronary angiography, whereas noninvasive imaging modalities (echocardiography, cardiac magnetic resonance imaging) play a complementary role. Early revascularization, percutaneous or pharmacological, represents key step in the management of RMVI. Maintenance of reasonable heart rate and atrioventricular synchrony is essential to sustain adequate cardiac output in these patients. When conventional treatment is not successful, mechanical circulatory support, including right ventricle assist devices, percutaneous cardiopulmonary support, and intra-aortic balloon pump, might be considered. The prognosis associated with RVMI is worse in the short term, compared to non-RVMI, but those patients who survive hospitalization have a relatively good long-term prognosis.
