Cardiac amyloidosis may result in an aggressive form of heart failure (HF). Cardiac contractility modulation (CCM) has been shown to be a concrete therapeutic option in patients with symptomatic HF, but there is no evidence of its application in patients with cardiac amyloidosis. We present the case of TTR amyloidosis, where CCM therapy proved to be effective. The patient had a history of multiple HF hospitalizations due to an established diagnosis of wild type TTR-Amyloidosis with significant cardiac involvement. Since he was highly symptomatic, except during continuous dobutamine and diuretic infusion, it was opted to pursue CCM therapy device implantation. At follow up, a significant improvement in clinical status was reported with an increase of EF, functional status (6 min walk test improved from zero meters at baseline, to 270 m at 1 month and to 460 m at 12 months), and a reduction in pulmonary pressures. One year after device implantation, no other HF hospital admission was needed. CCM therapy may be effective in this difficult clinical setting. The AMY-CCM Registry, which has just begun, will evaluate the efficacy of CCM in patients with HF and diagnosed TTR amyloidosis to bring new evidence on its potential impact as a therapeutic option.
Heart failure (HF) is a growing issue in developed countries; it is often the result of underlying processes such as ischemia, hypertension, infiltrative diseases or even genetic abnormalities. The great majority of the affected patients present a reduced ejection fraction (≤40%), thereby falling under the name of “heart failure with reduced ejection fraction” (HFrEF). This condition represents a major threat for patients: it significantly affects life quality and carries an enormous burden on the whole healthcare system due to its high management costs. In the last decade, new medical treatments and devices have been developed in order to reduce HF hospitalizations and improve prognosis while reducing the overall mortality rate. Pharmacological therapy has significantly changed our perspective of this disease thanks to its ability of restoring ventricular function and reducing symptom severity, even in some dramatic contexts with an extensively diseased myocardium. Notably, medical therapy can sometimes be ineffective, and a tailored integration with device technologies is of pivotal importance. Not by chance, in recent years, cardiac implantable devices witnessed a significant improvement, thereby providing an irreplaceable resource for the management of HF. Some devices have the ability of assessing (CardioMEMS) or treating (ultrafiltration) fluid retention, while others recognize and treat life-threatening arrhythmias, even for a limited time frame (wearable cardioverter defibrillator). The present review article gives a comprehensive overview of the most recent and important findings that need to be considered in patients affected by HFrEF. Both novel medical treatments and devices are presented and discussed.
Background: Residual risk after acute coronary syndromes (ACSs) continues to affect prognosis. We investigated the impact of female sex, non-ST-segment–elevation myocardial infarction (NSTEMI), diabetes mellitus (DM), and chronic kidney disease (CKD) on coronary atherosclerosis extent, culprit stenosis location, and bio-humoral data. The rate of both major adverse cardiovascular events (MACE) and non-fatal recurrent coronary events (RCE) was additionally evaluated. Methods: We enrolled 1404 ACS patients and followed them for up to 5 years. Coronary culprit and non-culprit stenoses were analyzed using angiography. Biohumoral data was assessed at admission and at 1 month and 12 months after discharge. Patients were compared based on sex, NSTEMI, DM, and CKD presence. Results: NSTEMI patients had a higher number of total coronary stenoses (3.5 vs. 3.3, p = 0.013) and non-culprit stenoses (2.3 vs. 1.6, p = 0.0001). Non-culprit percent stenosis was significantly greater in NSTEMI as compared to STEMI patients (57.9% vs. 47.1%, p = 0.0001). DM patients had a higher frequency of bifurcation lesions (41% vs. 25%, p = 0.0001). CKD patients showed a higher prevalence of left main disease (3.4% vs. 1.5%, p = 0.038). Female patients had higher LDL-cholesterol values at 1 month and 12 months. NSTEMI, DM, and creatinine level were independent predictors of MACE. NSTEMI patients had an increased risk of non-fatal RCE. Conclusions: NSTEMI, DM, and creatinine levels at admission were independent predictors of MACE in the first 5 years after an ACS.
Heart failure (HF) is a growing issue in developed countries and most patients present with a reduced ejection fraction. This condition significantly impairs quality of life and represents a threat not only for patients, but also for the entire healthcare system due to its high management cost. In the last decade, new medical treatments and devices have been developed to reduce HF hospitalizations and improve prognosis, while reducing the overall mortality rate. Medical therapy does not achieve the same results in all patients and, whenever it fails, technology comes in handy: novel devices for the management of HF have reduced symptoms. They have also improved the treatment of fluid retention and life threatening arrhythmias. The present review article gives to the readers a comprehensive overview of the most recent and important findings that need to be considered in HF with reduced ejection fraction patients. Both novel medical treatments and devices have been presented and discussed.
Infective endocarditis (IE) is a severe infectious disease affecting cardiac valves (either native or prosthetic) or implantable cardiac devices, and it is associated with high rates of morbidity and mortality. Recent data from the Global Burden of Disease study have shown a significant increase in both the incidence and mortality of IE. One-year mortality following diagnosis can reach up to 30%. IE can present with a wide range of clinical manifestations, and its course may be complicated by systemic embolic events or intracardiac complications such as abscess formation or prosthetic valve dehiscence. Echocardiography remains the first-line imaging modality; however, an integrated multimodality imaging approach is increasingly adopted in contemporary practice, incorporating both cardiac computed tomography and positron emission tomography. A multidisciplinary approach involving cardiologists, cardiac surgeons, internists, infectious disease specialists, and nuclear medicine physicians is often required to ensure accurate diagnosis and effective treatment of IE. The prognosis of infective endocarditis depends on early diagnosis, appropriate antimicrobial therapy, and timely surgical intervention when indicated. This review aims to summarize the current knowledge on IE, from pathophysiological insights to surgical strategies. It also focuses on practical recommendations to address the most pressing unmet clinical needs through a multidisciplinary approach.
Background: Transthyretin cardiac amyloidosis (ATTR-CM) is an infiltrative cardiomyopathy that frequently progresses to symptomatic heart failure (HF), often with mildly reduced or reduced ejection fraction (EF). Standard therapies are limited in NYHA III–IV, and Tafamidis is approved only for the early stages. Cardiac contractility modulation (CCM) therapy has shown promise in HF with reduced EF, but its role in ATTR-CM remains unexplored. Methods: This multicentric, prospective pilot study evaluated the safety and efficacy of CCM therapy in ten patients (n = 10) with ATTR-CM, EF between 25 and 45%, and NYHA class III–IV symptoms refractory to optimal medical therapy. All patients underwent implantation of the Optimizer CCM system and were followed for at least 12 months. The primary endpoint was the incidence of worsening heart failure (WHF); secondary endpoints included changes in EF, NYHA class, 6-minute walk test (6MWT), and quality of life metrics. Results: In this cohort (n = 10), CCM therapy significantly reduced WHF episodes (from 0.18 ± 0.09 to 0.025 ± 0.08 hospitalizations/patient-year, p < 0.001) and improved NYHA class and 6MWT (p < 0.001). EF increased by an average of 4.8 ± 6.1%, and 6MWT improved by 31.3 ± 53.3%. Importantly, all patients became eligible for Tafamidis after CCM therapy due to improved functional status. Conclusion: This pilot study suggests that CCM therapy is a feasible and potentially effective option for ATTR-CM patients with advanced HF who are not candidates for existing disease-modifying treatments. These findings support the rationale for larger studies, including the ongoing AMY-CCM registry (NCT05167799), to validate CCM’s therapeutic role in this population.
