Clinical Outcomes of Percutaneous Coronary Intervention in Amyloidosis, Sarcoidosis, and Hemochromatosis.

Background: Infiltrative diseases (IDs), including amyloidosis, sarcoidosis, and hemochromatosis, are characterized by abnormal cellular infiltration in multiple organs, including the heart. The prognosis of percutaneous coronary intervention (PCI) patients with underlying IDs has not been well-studied. We evaluated the prevalence of IDs in patients undergoing PCI and their association with post-PCI outcomes. Methods: The National Inpatient Sample (NIS) 2016-2020 database was used to identify PCI patients with ICD-10 codes for a retrospective analysis. PCI patients were then divided into those with and without underlying IDs, which included amyloidosis, sarcoidosis, and hemochromatosis. Multivariable logistic regression was performed for composite post-PCI outcomes analyses. Results: Among 2,360,860 patients admitted to undergo PCI, 7855 patients had underlying IDs. The highest prevalence was observed for sarcoidosis (0.2%) followed by hemochromatosis (0.07%) and amyloidosis (0.04%). Underlying amyloidosis was associated with worse composite post-PCI outcomes (odds ratio [OR], 1.6; 95% CI, 1.1-2.44; P = .02), including higher in-hospital mortality (OR, 1.9; 95% CI, 1.1-3.4; P = .04), higher risk of intra/post-PCI stroke (OR, 4.0; 95% CI, 1.1-16.0; P = .04), but not major bleeding (OR, 2.2; 95% CI, 0.97-5.03; P = .058). In contrast, underlying sarcoidosis (OR, 1.1; 95% CI, 0.87-1.41; P = .4), and hemochromatosis (OR, 1.18; 95% CI, 0.77-1.8; P = .44) were not associated with composite post-PCI outcomes. Amyloidosis patients undergoing PCI also had higher hospitalization charges ($212,123 vs $141,137; P = .03) and longer length of stay (8.2 vs 3.9 days; P < .001). Conclusions: Underlying amyloidosis was associated with worse post-PCI outcomes including higher in-hospital mortality, intra/post-PCI stroke, and socioeconomic burden. A multidisciplinary approach and future studies are needed to investigate the screening and treatment strategies in these patients.

Overview of Spanlastics: A Groundbreaking Elastic Medication Delivery Device with Versatile Prospects for Administration via Various Routes.

When compared to the challenges associated with traditional dosage forms, medication delivery systems based on nanotechnology have been a huge boon. One such candidate for medication delivery is spanlastics, an elastic nanovesicle that can transport a diverse array of medicinal compounds. The use of spanlastics has been associated with an increase in interest in alternative administration methods. The non-ionic surfactant or surfactant blend is the main component of spanlastics. The purpose of this review was primarily to examine the potential of spanlastics as a delivery system for a variety of medication classes administered via diverse routes. Science Direct, Google Scholar, and Pubmed were utilized to search the academic literature for this review. Several studies have demonstrated that spanlastics greatly improve therapeutic effectiveness, increase medication absorption, and decrease drug toxicity. This paper provides a summary of the composition and structure of spanlastics along with their utility in the delivery of various therapeutic agents by adopting different routes. Additionally, it provides an overview of the numerous disorders that may be treated using drugs that are contained in spanlastic vesicles.

Thirty-day hospital readmission in females with acute heart failure and breast cancer: A retrospective cohort study from national readmission database.

BACKGROUND: Breast Cancer and cardiovascular diseases are amongst the two leading causes of mortality in the United States, and the two conditions are connected in part because of recognized cardiotoxicity of cancer treatments. The aim of this study is to investigate the predictors risk factors for thirty-day readmission in female breast cancer survivors presenting with acute heart failure. METHODS: This is a retrospective cohort study of acute heart failure (AHF) hospitalization in female patients with breast cancer in 2019 using the National Readmission Database (NRD), which is the largest publicly available all-payer inpatient readmission database in the United States. Our study sample included adult female patients aged 18 years and older. The primary outcome of interest was the rate of 30- day readmission. RESULTS: In 2019, there were 8332 total index admissions for AHF in females with breast cancer and 7776 patients were discharged alive. The mean age was 74.4 years (95% CI: 74, 74.7). The percentage of readmission at 30 days among those discharged alive was 21.8% (n = 1699). Hypertensive heart disease with chronic kidney disease accounted for the majority of readmission in AHF with breast cancer followed by sepsis, acute kidney injury, respiratory failure, pneumonia, and atrial fibrillation. Demographic factors including higher burden of comorbidities predict readmission. The total in-hospital mortality in index admission was 6.67% (n = 556) and for readmitted patients was 8.77% (n = 149). The mean length of stay for index admission was 7.5 days (95% CI: 7.25, 7.75). CONCLUSIONS: Readmission of female breast cancer survivors presenting with AHF is common and largely be attributed to high burden of comorbidities including hypertension, and chronic kidney disease. A focus on close outpatient follow-up will be beneficial in lowering readmissions.

Mechanical Circulatory Support Devices in Patients with High-Risk Pulmonary Embolism.

Pulmonary embolism (PE) is a common acute cardiovascular condition. Within this review, we discuss the incidence, pathophysiology, and treatment options for patients with high-risk and massive pulmonary embolisms. In particular, we focus on the role of mechanical circulatory support devices and their possible therapeutic benefits in patients who are unresponsive to standard therapeutic options. Moreover, attention is given to device selection criteria, weaning protocols, and complication mitigation strategies. Finally, we underscore the necessity for more comprehensive studies to corroborate the benefits and safety of MCS devices in PE management.

Maternal and Fetal Outcomes in Pulmonary Hypertension During Pregnancy: A Contemporary Nationwide Analysis.

Pulmonary hypertension (PH) disproportionately affects women, presenting challenges during pregnancy. Historically, patients with PH are advised to avoid pregnancy; however, recent reports have indicated that the incidence of adverse events in pregnant patients with PH may be lower than previously reported. We conducted a retrospective cohort study in pregnant patients with PH using the National Readmission Database from January 1, 2016, to December 31, 2020. PH was categorized according to the World Health Organization classification. Primary end points include maternal mortality and 30-day nonelective readmission rate. Other adverse short-term maternal (cardiovascular and obstetric) and fetal outcomes were also analyzed. Of 9,922,142 pregnant women, 3,532 (0.04%) had PH, with Group 1 PH noted in 1,833 (51.9%), Group 2 PH in 676 (19.1%), Group 3 PH in 604 (17.1%), Group 4 PH in 23 (0.7%), Group 5 PH in 98 (2.8%), and multifactorial PH in 298 (8.4%). PH patients exhibited higher rates of adverse cardiovascular events (15.7% vs 0.3% without PH, p <0.001) and mortality (0.9% vs 0.01% without PH, p <0.001). Mixed PH and Group 2 PH had the highest prevalence of adverse cardiovascular events in the World Health Organization PH groups. Patients with PH had a significantly higher nonelective 30-day readmission rate (10.4% vs 2.3%) and maternal adverse obstetric events (24.2% vs 9.1%) compared with those without PH (p <0.001) (Figure 1). In conclusion, pregnant women with PH had significantly higher adverse event rates, including in-hospital maternal mortality (85-fold), compared with those without PH.

Collating the voice of people with autoimmune diseases: Methodology for the Third Phase of the COVAD Studies.

INTRODUCTION: The growing recognition of holistic patient care highlights the various factors shaping the quality of life of individuals with autoimmune and rheumatic diseases (AIRDs). Beyond the traditional disease measures, there is an emerging acknowledgment of the less-explored aspects, including subjective well-being, social determinants of health, comorbidities, mental health, and medication adherence. Moreover, digital health services have empowered patients to engage actively in decision-making alongside clinicians. To explore these domains within the context of AIRDs, the "Collating the Voice of People with Autoimmune Diseases" COVAD survey was conceived, a successor of the previous two COVAD surveys. In this document, we present the study protocol in comprehensive detail. METHODS: The COVAD-3 survey is a cross-sectional patient self-reported e-survey incorporating multiple widely accepted scales/scores to assess various aspects of patients' lifestyles objectively. To ensure the survey's accuracy and usability across diverse regions, it will be translated into multiple languages and subjected to rigorous vetting and pilot testing. It will be distributed by collaborators via online platforms and data will be collected from patients with AIRDs, and healthy individuals over eight months. Data analysis will focus on outcome measures related to various social, demographic, economic, and psychological factors. CONCLUSION: With the increasing awareness to adopt a holistic treatment approach encompassing all avenues of life, the COVAD-3 survey aims to gain valuable insights into the impact of social, demographic, economic, and psychological determinants of health on the subjective well-being in patients with AIRDs, which will contribute to a better understanding of their overall health and well-being.

Status and Future Directions for Balloon Pulmonary Angioplasty in Chronic Thromboembolic Pulmonary Disease With and Without Pulmonary Hypertension: A Scientific Statement From the American Heart Association.

Balloon pulmonary angioplasty continues to gain traction as a treatment option for patients with chronic thromboembolic pulmonary disease with and without pulmonary hypertension. Recent European Society of Cardiology guidelines on pulmonary hypertension now give balloon pulmonary angioplasty a Class 1 recommendation for inoperable and residual chronic thromboembolic pulmonary hypertension. Not surprisingly, chronic thromboembolic pulmonary hypertension centers are rapidly initiating balloon pulmonary angioplasty programs. However, we need a comprehensive, expert consensus document outlining critical concepts, including identifying necessary personnel and expertise, criteria for patient selection, and a standardized approach to preprocedural planning and establishing criteria for evaluating procedural efficacy and safety. Given this lack of standards, the balloon pulmonary angioplasty skill set is learned through peer-to-peer contact and training. This document is a state-of-the-art, comprehensive statement from key thought leaders to address this gap in the current clinical practice of balloon pulmonary angioplasty. We summarize the current status of the procedure and provide a consensus opinion on the role of balloon pulmonary angioplasty in the overall care of patients with chronic thromboembolic pulmonary disease with and without pulmonary hypertension. We also identify knowledge gaps, provide guidance for new centers interested in initiating balloon pulmonary angioplasty programs, and highlight future directions and research needs for this emerging therapy.

In-Hospital Outcomes of Combined Coronary Revascularization and Transcatheter Aortic Valve Implantation in Inpatient Nationwide Analysis.

Transcatheter aortic valve implantation (TAVI) is accepted as an alternative to surgery, but data on combined percutaneous coronary interventions (PCI) and TAVI during the same in-hospital stay are still lacking. Using the national inpatient sample (NIS) database, we identified all TAVI encounters and compared in-hospital outcomes of patients who had TAVI only to patients who had TAVI and PCI. We used multivariable logistic regression analysis to calculate the adjusted odds ratio (aOR). Of 291,810 patient encounters with TAVI, 13,114 (4.5%) had combined PCI during the same index admission. The average age was 79.61 ± 8.61 years in the TAVI-only vs 80.25 ± 8.73 years in the combined TAVI-PCI group. Combined TAVI and PCI was associated with higher in-hospital mortality (4.5% vs 1.8%, aOR: 2.3), stroke (4.7% vs 2.9%, aOR: 1.4), net adverse events (NAE) (20.2% vs 5.7%, aOR: 3.6), major bleeding (40.1% vs 24.3%, aOR: 1.8), vascular complications (10.6% vs 2.5%, aOR: 3.9), acute kidney injury (AKI) (23.3% vs 11.7%, aOR: 2.1), hemodialysis (HD) (4.2% vs 2.4%, aOR: 1.4), postoperative cardiogenic shock (1.2% vs 0.4%, aOR: 2.8), need for mechanical circulatory support (6.9% vs 1%, aOR: 7); p-value < 0.001 for all. The utilization of permanent pacemakers was similar between the groups (9.8% vs 9.2%, aOR: 1; p = 0.6). Combining TAVI and PCI during the same index admission is associated with worse outcomes. The decision to do PCI for patients undergoing TAVI should be individualized and tailored based on the patient's clinical conditions.

Introduction: Cardiovascular diseases are associated with increased morbidity and mortality among CKD (chronic kidney disease) population. Recent studies have found increasing prevalence of PH (pulmonary hypertension) in CKD population. Present study was done to determine prevalence and predictors of LV (left ventricular) systolic dysfunction, LVDD (left ventricular diastolic dysfunction) and PH in CKD 3b-5ND (non-dialysis) patients. Methods: A cross sectional observational study was done from Jan/2020 to April/2021. CKD 3b-5ND patients aged ≥15 yrs were included. Transthoracic 2D (2 dimensional) echocardiography was done in all patients. PH was defined as if PASP (pulmonary artery systolic pressure) value above 35mm Hg, LV systolic dysfunction was defined as LVEF (left ventricular ejection fraction)≤50% and LVDD as E/e′ ratio >14 respectively. Multivariate logistic regression model was done to determine the predictors. Results: A total of 378 patients were included in the study with 103 in stage 3b, 175 in stage 4 and 100 patients in stage 5ND. Prevalence of PH was 12.2%, LV systolic dysfunction was 15.6% and LVDD was 43.65%. Predictors of PH were duration of CKD, haemoglobin, serum 25-OH vitamin D, serum iPTH (intact parathyroid hormone) and serum albumin. Predictors of LVDD were duration of CKD and presence of arterial hypertension. Predictors of LV systolic dysfunction were eGFR (estimated glomerular filtration rate), duration of CKD, serum albumin and urine protein. Conclusion: In our study of 378 CKD 3b-5ND patients prevalence of PH was 12.2%, LV systolic dysfunction was 15.6% and LVDD was 43.65%. (AU)

Estudios recientes han encontrado un aumento de la prevalencia de la hipertensión pulmonar (HP) en la población con ERC. El presente estudio se llevó a cabo para determinar la prevalencia y los predictores de la disfunción sistólica del ventrículo izquierdo (VI), la disfunción diastólica del VI y la hipertensión pulmonar en pacientes con ERC 3b -5ND (sin diálisis). Métodos: Se realizó un estudio observacional transversal desde enero/2020 hasta abril/2021. Se incluyeron pacientes con ERC 3b -5ND de edad ≥15 años. Se realizó una ecocardiografía transtorácica 2D (bidimensional) a todos los pacientes. La HP se definió como un valor de presión sistólica de la arteria pulmonar superior a 35mm Hg, la disfunción sistólica del VI se definió como una fracción de eyección del ventrículo izquierdo ≤ 50% y la DVL como una relación E/e′>14 respectivamente. Se realizó un modelo de regresión logística multivariante para determinar los predictores. Resultados: Un total de 378 pacientes fueron incluidos en el estudio con 103 en estadio 3b, 175 en estadio 4 y 100 pacientes en estadio 5ND. La prevalencia de la HP fue del 12,2%, la disfunción sistólica del VI fue del 15,6% y la DVL fue del 43,65%. Los predictores de la HP fueron la duración de la ERC, la hemoglobina, la vitamina D 25-OH en suero, la iPTH en suero (hormona paratiroidea intacta) y la albúmina en suero. Los predictores de la EVL fueron la duración de la ERC y la presencia de hipertensión arterial. Los predictores de la disfunción sistólica del VI fueron la tasa de filtración glomerular estimada, la duración de la ERC, la albúmina sérica y las proteínas en orina. Conclusión: En nuestro estudio de 378 pacientes con ERC 3b-5ND la prevalencia de la HP fue del 12,2%, la disfunción sistólica del VI fue del 15,6% y la DVL fue del 43,65%. (AU)

Comparative Outcomes of Catheter-Directed Thrombolysis Plus Systemic Anticoagulation Versus Systemic Anticoagulation Alone in the Management of Intermediate-Risk Pulmonary Embolism in a Systematic Review and Meta-Analysis.

There are limited and conflicting data on the initial management of intermediate-risk (or submassive) pulmonary embolism (PE). This study sought to compare the outcomes of catheter-directed thrombolysis (CDT) in combination with systemic anticoagulation (SA) to SA alone. A systematic search was conducted in MEDLINE, EMBASE, PubMed, and the Cochrane databases from inception to March 1, 2023 for studies comparing the outcomes of CDT + SA versus SA alone in intermediate-risk PE. The outcomes were in-hospital, 30-day, 90-day, and 1-year mortality; bleeding; blood transfusion; right ventricular recovery; and length of stay. Random-effects models was used to calculate the pooled incidence and risk ratios (RRs) with 95% confidence intervals (CIs). A total of 15 (2 randomized and 13 observational) studies with 10,549 (2,310 CDT + SA and 8,239 SA alone) patients were included. Compared with SA, CDT + SA was associated with significantly lower in-hospital mortality (RR 0.41, 95% CI 0.30 to 0.56, p <0.001), 30-day mortality (RR 0.34, 95% CI 0.18 to 0.67, p = 0.002), 90-day mortality (RR 0.34, 95% CI 0.17 to 0.67, p = 0.002), and 1-year mortality (RR 0.58, 95% CI 0.34 to 0.97, p = 0.04). There were no significant differences between the 2 cohorts in the rates of major bleeding (RR 1.39, 95% CI 0.72 to 2.68, p = 0.56), minor bleeding (RR 1.83, 95% CI 0.97 to 3.46, p = 0.06), and blood transfusion (RR 0.34, 95% CI 0.10 to 1.15, p = 0.08). In conclusion, CDT + SA is associated with significantly lower short-term and long-term all-cause mortality, without any differences in major/minor bleeding, in patients with intermediate-risk PE.

Sex, Racial, and Geographic Disparities in Pulmonary Embolism-related Mortality Nationwide.

Rationale: Acute pulmonary embolism is a leading cause of cardiovascular death. There are limited data on the national mortality trends from pulmonary embolism. Understanding these trends is crucial for addressing the mortality and associated disparities associated with pulmonary embolism. Objectives: To analyze the national mortality trends related to acute pulmonary embolism and determine the overall age-adjusted mortality rate (AAMR) per 100,000 population for the study period and assess changes in AAMR among different sexes, races, and geographic locations. Methods: We conducted a retrospective cohort analysis using mortality data of individuals aged ⩾15 years with pulmonary embolism listed as the underlying cause of death in the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research database from January 2006 to December 2019. These data are produced by the National Center for Health Statistics. Results: A total of 109,992 pulmonary embolism-related deaths were noted in this dataset nationwide between 2006 and 2019. Of these, women constituted 60,113 (54.7%). The AAMR per 100,000 was not significantly changed, from 2.84 in 2006 to 2.81 in 2019 (average annual percentage change [AAPC], 0.2; 95% confidence interval [CI], -0.1 to 0.5; P = 0.15). AAMR increased for men throughout the study period compared with women (AAPC, 0.7 for men; 95% CI, 0.3 to 1.2; P = 0.004 vs. AAPC, -0.4 for women; 95% CI, -1.1 to 0.3; P = 0.23, respectively). Similarly, AAMR for pulmonary embolism increased for Black compared with White individuals, from 5.18 to 5.26 (AAPC, 0.4; 95% CI, 0.0 to 0.7; P = 0.05) and 2.82 to 2.86 (AAPC, 0.0; 95% CI, -0.6 to 0.6; P = 0.99), respectively. Similarly, AAMR for pulmonary embolism was higher in rural areas than in micropolitan and large metropolitan areas during the study period (4.07 [95% CI, 4.02 to 4.12] vs. 3.24 [95% CI, 3.21 to 3.27] vs. 2.32 [95% CI, 2.30-2.34], respectively). Conclusions: Pulmonary embolism mortality remains high and unchanged over the past decade, and enduring sex, racial and socioeconomic disparities persist in pulmonary embolism. Targeted efforts to decrease pulmonary embolism mortality and address such disparities are needed.

Expert Recommendations on Optimizing the Diagnosis and Management of Gastroesophageal Reflux Disease Associated with Comorbidities in the Indian Population.

Gastroesophageal reflux disease (GERD) is among the most prevalent gastrointestinal (GI) disorders. It is known to often coexist with other chronic diseases such as asthma, chronic obstructive pulmonary disease (COPD), obesity, diabetes mellitus (DM), and hypertension. Upper endoscopy, esophageal manometry, and impedance-pH monitoring are a few invasive diagnostic options that are reserved for selected GERD patients. Symptom assessment by using questionnaires, such as the frequency scale for the symptoms of GERD (FSSG), is simple, convenient, noninvasive, and inexpensive. These questionnaires are widely used to facilitate diagnosis and appropriate treatment. Early diagnosis of GERD and timely management may improve clinical outcomes in patients. Proton pump inhibitors (PPIs) are the preferred therapy for GERD. However, evidence indicates that excessive and extended use of PPIs is linked to adverse events. An overview of the diagnosis and management of GERD, as well as an evidence-based overview of the relationship between GERD and asthma, COPD, obesity, DM, and hypertension, is presented in this review. Expert opinions and recommendations for diagnosing GERD using invasive tests and validated questionnaires have also been mentioned.

The Intersection of Pulmonary Vascular Disease and Hypoxia-Inducible Factors.

Hypoxia-inducible factors (HIFs) are a family of nuclear transcription factors that serve as the master regulator of the adaptive response to hypoxia. In the lung, HIFs orchestrate multiple inflammatory pathways and signaling. They have been reported to have a major role in the initiation and progression of acute lung injury, chronic obstructive pulmonary disease, pulmonary fibrosis, and pulmonary hypertension. Although there seems to be a clear mechanistic role for both HIF 1α and 2α in pulmonary vascular diseases including PH, a successful translation into a definitive therapeutic modality has not been accomplished to date.

Effects of Valvular Heart Disease on Clinical Outcomes in Sarcoidosis.

Systemic sarcoidosis can lead to heart failure, conduction abnormalities and ventricular arrhythmias although data on concomitant valvular heart disease (VHD) is limited. We reported the prevalence and outcomes of VHD in systemic sarcoidosis. A retrospective cohort study was conducted using National Inpatient Sample between 2016 and 2020 with respective ICD-10-CM codes. 406,315 patients were hospitalized with sarcoidosis, out of which 20,570 had comorbid VHD (5.1%). Mitral disease was most common (2.5%), followed by aortic, and tricuspid disease. Tricuspid disease was associated with increased mortality in sarcoidosis (OR 1.6, 95% CI, 1.1-2.6, P = 0.04), while aortic disease was associated with higher mortality in only 31-50 years age cohort. Patients with sarcoidosis and VHD have higher hospitalization charges and lower or similar valvular intervention rates than those without sarcoidosis. VHD has a prevalence of 5% in sarcoidosis, predominantly affecting mitral and aortic valves. Underlying VHD is associated with worse outcomes in sarcoidosis.

Periprocedural Complications With Balloon Pulmonary Angioplasty: Analysis of Global Studies.

BACKGROUND: Balloon pulmonary angioplasty (BPA) was introduced as a treatment modality for patients with inoperable, medically refractory chronic thromboembolic pulmonary hypertension decades ago; however, reports of high rates of pulmonary vascular injury have led to considerable refinement in procedural technique. OBJECTIVES: The authors sought to better understand the evolution of BPA procedure-related complications over time. METHODS: The authors conducted a systematic review of original articles published by pulmonary hypertension centers globally and performed a pooled cohort analysis of procedure-related outcomes with BPA. RESULTS: This systematic review identified 26 published articles from 18 countries worldwide from 2013 to 2022. A total of 1,714 patients underwent 7,561 total BPA procedures with an average follow up of 7.3 months. From the first period (2013-2017) to the second period (2018-2022), the cumulative incidence of hemoptysis/vascular injury decreased from 14.1% (474/3,351) to 7.7% (233/3,029) (P < 0.01); lung injury/reperfusion edema decreased from 11.3% (377/3,351) to 1.4% (57/3,943) (P < 0.01); invasive mechanical ventilation decreased from 0.7% (23/3,195) to 0.1% (4/3,062) (P < 0.01); and mortality decreased from 2.0% (13/636) to 0.8% (8/1,071) (P < 0.01). CONCLUSIONS: Procedure-related complications with BPA, including hemoptysis/vascular injury, lung injury/reperfusion edema, mechanical ventilation, and death, were less common in the second period (2018-2022), compared with first period (2013-2017), likely from refinement in patient and lesion selection and procedural technique over time.

Varied Presentation of Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy (ARVD/C): A Case Series.

Arrhythmogenic right ventricular dysplasia (ARVD) is a genetically predisposed form of cardiomyopathy that mainly affects young individuals resulting in fatal ventricular arrhythmias leading to sudden cardiac death. ARVD has 50% of cases that involve both the right ventricle (RV) and left ventricle (LV), but only a small number of cases involve an isolated left ventricle. In this case series, five patients (four males and one female) with a diagnosis of ARVD presented to our center with varied clinical presentations across a wide range of age groups. The MRI of all five cases showed dilated right atrium (RA)/RV with right ventricular free wall dyskinesia. Two-dimensional (2D) MRI showed aneurysmal outpouching with diffuse free wall enhancement. Automated implantable cardioverter defibrillator (AICD) was implanted uneventfully in all five patients, and the patients were discharged with oral medications such as low-dose diuretics, beta-blockers, spironolactone, angiotensin-converting enzymes (ACE) inhibitors, amiodarone, and anxiolytics. Until now, the patients were doing well on follow-up visits. The therapeutic management of patients with arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) has evolved over the years and continues to be an important challenge. To further improve risk stratification and treatment of patients, more information is needed on natural history, long-term prognosis, and risk assessment. Special attention should be focused on the identification of patients who would benefit from implantable cardioverter-defibrillator (ICD) implantation in comparison to pharmacological and other nonpharmacological approaches.
