Obstetric anesthesia management of dilated cardiomyopathies and heart failure: a narrative review.

Pregnancy in patients with dilated cardiomyopathy carries a significantly increased risk of maternal mortality or severe morbidity, and pregnancy is typically considered contraindicated for patients with severely reduced ventricular function. Nonetheless, anesthesiologists will still encounter patients with cardiomyopathy requiring delivery or termination care. This review describes how NT-ProBNP testing and echocardiography can help with early recognition of heart failure in pregnancy, and describes a suggested approach to anesthetic management of patients with cardiomyopathies or acute heart failure, including hemodynamic goals, use of vasoactive medications and mechanical support. Vaginal delivery, with effective neuraxial anesthesia is the preferred mode of delivery in most patients with cardiomyopathy, with cesarean delivery reserved for maternal or fetal indications. The Pregnancy Heart Team is vital in coordinating the multidisciplinary care necessary to safely support these patients through pregnancy.

The Heart Team during the Pandemic: A Case Report of Bio-Prosthesis Degeneration Treated with Valve in Valve Implantation.

The pandemic changed the type of patients. The concept of "patient at the center" became concrete. The execution of simple consultancy was overcome to create effective collaboration and fruitful exchanges between specialists. The "Heart Team" model is on increasing affirmation. The TEAM-BASED approach in the cardiology field is successfully used in patients suffering from ischemic heart disease and valvulopathies for the choice of possible treatments. Degenerative type Sao is the most frequent valvulopathy among the valvulopathies in Western countries and its incidence is correlated with age. In high-risk patients, percutaneous valve replacement (transcatheter aortic valve implantation) is the most valid therapeutic option. The implantation of biological prostheses raises the problem of both degeneration and dysfunction of the prosthesis itself over time in subjects of advanced age and with comorbidities. In this scenario, valve-in-valve (VinV) is a valid therapeutic alternative in high-risk patients. A clinical case of aortic prosthetic degeneration, as an outcome of endocarditis, treated with VinV is presented. The therapeutic decision was made by an "Electronic Heart Team" which represents a further evolution of the treatment pathways and reduces the distance between the specialists in "Hub" Centers and the "Spoke" center.

Treatment Adherence Rates and Long-Term Mortality in a Quaternary Multidisciplinary Heart Team: An Observational Cohort.

BACKGROUND: A multidisciplinary heart team (HT) approach to patients with complex coronary artery disease has a class IB recommendation, yet there are limited data on adherence to HT treatment recommendations and long-term clinical follow-up. The objective of this study was to assess adherence rates to HT recommendations and assess long-term mortality rates among patients with complex CAD. METHODS AND RESULTS: Six hundred eighty-four sequential HT cases for complex coronary artery disease from January 2015 to May 2017 were reviewed. After excluding cases with significant comorbid valve disease, baseline characteristics were compared based on HT treatment recommendations: optimal medical therapy, percutaneous coronary intervention, and coronary artery bypass grafting. Adherence rates were manually extracted, and 5-year mortality rates were obtained from the Michigan Death Registry. Seventy-two percent of 405 included patients were men (mean age 66±11 years), with high rates of medical comorbidities. Estimated surgical risk scores were lowest in the coronary artery bypass grafting group. Optimal medical therapy was recommended in 138 patients (34%), percutaneous coronary intervention in 95 (23%), and coronary artery bypass grafting in 172 (42%). Adherence to HT recommendations across groups was high (96%) and did not differ between treatment groups. Over 5 years of follow-up, there were 119 deaths, resulting in a cumulative mortality rate of 29%. CONCLUSIONS: In the largest HT cohort in the United States to date, high rates of adherence to HT recommendations were observed among high-risk patients with coronary artery disease. High rates of adherence to HT recommendations were observed irrespective of treatment group recommendation, suggesting that HT recommendations were individualized and acceptable to both patients and physicians alike.

Emergent Surgical Replacement of a Tendyne Prosthesis for Bioprosthetic Valve Thrombosis.

A 66-year-old woman with a complex medical history underwent transcatheter mitral valve replacement (TMVI) owing to mitral insufficiency. Risk factors and noncompliance led to bioprosthetic valve thrombosis (BPVT) within 3 years. Emergent surgery indicated by an ad hoc heart team successfully managed the situation, showcasing challenges in BPVT management after TMVI.

Rupture of the ascending aorta 6 months after TAVI procedure caused by TAVI prosthesis.

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is indicated for elderly patients who often have severe comorbidities and high operative risk. Despite many advantages, it carries the potential for both early and late complications. The literature reports mainly periprocedural problems. This case report describes a rare instance of ascending aortic rupture as a late complication following TAVI. CASE PRESENTATION: An 81-year-old male with severe aortic stenosis (AS) was a non-surgical patient due to a high operative risk (EuroSCORE II 14.08%) and comorbidities, including cardiovascular problems, chronic obstructive pulmonary disease, myelodysplastic syndrome. During the TAVI procedure Medtronic CoreValve™ Evolut™ R-26 was implanted via the right femoral artery. Postoperative period elapsed without complications and the patient was discharged home. Six months later, the patient was re-admitted to the hospital on an emergency basis and transferred directly to the operating room due to ascending aortic rupture (EuroSCORE II 53.20%, GERAADA score 64.9%). Computed tomography angiography (CTA) showed aortic rupture with a multiple fresh blood reservoirs and thrombus around the ascending aorta originating from the spot where the nitinol frame of the TAVI valve was attached to the native aorta. Supracoronary excision of the ascending aorta with implantation of a vascular graft (Intergard Woven Graft 34 mm) was performed, preserving the earlier implanted TAVI valve. On the 9th day after surgery the patient's general condition deteriorated, he suffered from circulatory and respiratory insufficiency. Furthermore, a gastrointestinal bleeding with the need for gastro-, and colonoscopy and multiple blood transfusions occurred. Patient developed urosepsis and acute renal failure with the need for hemodiafiltration. Despite intensive treatment, further deterioration of the medical condition of the patient. and finally the multiple organ failure was observed. Patient died on the 50th postoperative day. CONCLUSIONS: TAVI is a safe method of treating severe AS, especially recommended for non-surgical candidates. Rupture of the ascending aorta is a rare but serious complication of TAVI that usually occur during or shortly after the procedure. This case report highlights the importance of post-procedural monitoring for such TAVI complications, even in the late period following TAVI, and if such complications occur, taking the risk to perform a life-saving operation.

Geriatricians' role in the management of aortic stenosis in frail older patients: a decade later.

INTRODUCTION: Increasing evidence supports the implementation of geriatric assessment in the workup of older patients with aortic stenosis (AS). In 2012, an online European survey revealed that geriatricians were rarely involved in the assessment of candidates for transcatheter aortic valve implantation (TAVI). After a "call to action" for early involvement of geriatricians in AS evaluation, the survey was repeated in 2022. Our aim was to investigate whether geriatricians' role changed in the last decade. METHODS: Online survey conducted between December 16th, 2021, and December 15th, 2022. All members of the European Geriatric Medicine Society were invited to participate. The survey included 26 questions regarding geriatricians' experience with AS and TAVI. RESULTS: Among 193 respondents (79.8% geriatricians), 73 (38%) reported to be involved in AS evaluation at least once a week. During 2 years prior to the survey, 43 (22.3%) had referred > 50% of their patients with severe AS for TAVI. Age influenced TAVI referral in a considerable proportion of respondents (36.8%). TAVI candidates were mainly referred to specialised cardiac centres with multidisciplinary teams (91.8%), including (47.2%) or not including (44.6%) a geriatrician. A total of 38.9% of respondents reported to be part of a multidisciplinary heart team. Geriatricians were less frequently involved (37%) than cardiologists (89.6%) and surgeons (53.4%) in pre-procedural TAVI management. Cardiologists were more frequently involved (85.5%) than geriatricians (33.7%) and surgeons (26.9%) in post-procedural management. CONCLUSIONS: Geriatricians' involvement in AS management and multidisciplinary heart teams remains scarce. More efforts should be devoted to implement geriatricians' role in AS decision-making.

Minimally Invasive Isolated and Hybrid Surgical Revascularization for Multivessel Coronary Disease: A Single-Center Long-Term Follow-Up.

INTRODUCTION: Some evidence suggests that surgical minimally invasive (MIDCAB) and hybrid coronary revascularization (HCR) are safe and potentially effective at short-term follow-up. Data on long-term outcomes are more limited and inconclusive. METHODS: Between February 2013 and December 2023, a total of 1997 patients underwent surgical coronary artery revascularization at our institution, of whom, 92 (4.7%) received left anterior mini-thoracotomy access (MIDCAB), either isolated (N = 78) or in combination with percutaneous coronary intervention (N = 14, HCR group). RESULTS: After a median follow-up of 75 months (range 3.1: 149 months), cardiac mortality was 0% while overall mortality was 3%, with one in-hospital mortality and two additional late deaths. Conversion to sternotomy happened in two patients (2.1%), and surgical re-explorations occurred in five patients (4.6%), of whom three for bleeding and two for graft failure. All patients received left internal mammary (LIMA) to left anterior descending artery (LAD) grafting (100%). In the HCR group, 10 patients (72%) showed percutaneous revascularization (PCI) after MIDCAB, showing PCI on a mean of 1.6 ± 0.6 vessels and implanting 2.1 ± 0.9 drug-eluting stents. CONCLUSIONS: MIDCAB, in isolation or in association with hybrid coronary revascularization, is associated with encouraging short- and long-term results in selected patients discussed within a dedicated heart-team.

PreScheck Team Study: prehabilitation clinic as an effective patient management tool in elective cardiac surgery.

INTRODUCTION: The main purpose of the study was to assess the impact of preoperative interdisciplinary assessment by the PreScheck Team on optimization of the final selection for elective cardiac surgery. MATERIAL AND METHODS: This is a single-centre prospective observational study. The examined population consisted of 933 adult patients planned for cardiac surgery. After the exclusion of urgent operations, the study group consisted of 288 patients planned for elective cardiac surgery within 3 months from 1.01.2023 with PreScheck assessment (PreScheck Team group 2) and a control group of 311 patients scheduled for elective cardiac surgery between 1.03.2022 and 30.06.2022 (4 months), without preoperative interdiscipli-nary assessment (No PreScheck Team group 2). RESULTS: Fifty-two patients (18.06%) from the study group were finally excluded from the surgery on the scheduled date. In 46 patients (88.46%) the temporary or permanent exclusion from surgery was a result of PreScheck Team assessment. In the control group 42 patients (13.5%) did not undergo surgery on the scheduled date. Twenty-seven of those patients (8.97%) were permanently excluded from cardiac surgery after admission to the hospital and required additional tests before the final clinical decision, with total hospitalization time of 146 days. CONCLUSIONS: Pre Surgery Check (PreScheck) Team is an original concept that combines classical preoperative assessment and an outpatient prehabilitation clinic. The approach we are proposing here should be a complementary stage in the process of selection for elective cardiac surgery, in addition to the Heart Team recommendation. This two-step decision-making enables real individual risk assessment, selection of the most suitable intervention and better use of medical resources.

Percutaneous axillary extracorporeal membrane oxygenation supported complex left main bifurcation percutaneous coronary intervention.

A 66-year-old man with multiple comorbidities including severe peripheral artery disease and heart failure with reduced ejection fraction presented with complex coronary artery disease with an elevated Society of Thoracic Surgeons Predicted Risk of Mortality for coronary artery bypass grafting and a Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery score of 18. With a multidisciplinary heart team approach, the patient successfully underwent percutaneous axillary venoarterial extracorporeal membrane oxygenation (VA-ECMO) supported high-risk percutaneous coronary intervention of a heavily calcified left main bifurcation lesion. Given the patient's peripheral artery disease, alternative arterial access for ECMO cannulation was performed percutaneously via the right axillary artery. Additionally, adequate coronary calcium modification was critical to successful stenting of a heavily calcified left main bifurcation. This case highlights a novel approach to obtaining alternative arterial access for ECMO cannulation and emphasizes the importance of calcium modification to achieve excellent stent results.

Hybrid extracorporeal cannulation for aortic root pseudoaneurysm re-operation: The role of a multidisciplinary team.

Introduction: Adequate cerebral protection for aortic reoperation is challenging and optimal technique is still controversial.Case Report: We report a hybrid cannulation approach to achieve safe cerebral protection during circulatory arrest to repair an aortic root pseudoaneurysm.Conclusion: A multidisciplinary approach combining conventional techniques and interventional expertise could be considered in complex aortic scenario.

Spontaneous pregnancy-associated coronary artery dissection: a case report on diagnostic and therapeutic challenges.

Background: One of the main causes of myocardial infarction during pregnancy is spontaneous coronary artery dissection. This is ascribed to hormonal changes during pregnancy leading to a weakening of the vessel wall and haemodynamic changes especially during childbirth. Management options include conservative medical treatment and percutaneous coronary intervention, depending on clinical presentation. Case summary: A 37-year-old woman presented with typical chest pain six weeks after giving birth to her third child. Echocardiography revealed a moderate reduction in systolic function. Initial invasive coronary angiography showed no abnormalities. After cardiac magnetic resonance demonstrated extensive scar, invasive coronary angiography was repeated including intravascular imaging. A dissection of the left anterior descending artery was visualized and treated by percutaneous coronary intervention and stenting. Left ventricular function was normalized at three-month follow-up. In this educational case report, we highlight the diagnostic and therapeutic challenges when treating this special patient cohort and the importance of cardiovascular imaging. Discussion: Pregnancy-associated spontaneous coronary dissection is a potential differential diagnosis when treating post-partum women with recent onset chest pain. Management is challenging and intravascular imaging to visualize dissection should be performed during invasive coronary angiography. Patients require interdisciplinary care within a pregnancy heart team.

[Une combinaison très rare de thrombose veineuse et artérielle chez un patient atteint du COVID 19]. / A very rare combination of venous and arterial thrombosis in a patient with COVID-19.

COVID-19 is an infectious disease caused by the SARS-CoV-2 virus. This epidemic has caused serious socio-economic problems worldwide, with a very high mortality rate. Several articles have been published in the literature showing the consequences of this disease on the human body. Among the most serious complications are venous and arterial thrombosis, which are rarely observed together in the same patient. In this article, we report an exceptional case of a patient with COVID-19 with the combination of intracardiac thrombus (left atrium) and venous thrombosis (splenic vein and portal trunk).

[Catheter-based and surgical treatment for aortic valve diseases]. / Katheterbasierte und operative Therapie bei Aortenvitien.

The pathophysiology of aortic valve diseases is of predominantly degenerative nature, characterized by calcific aortic valve stenosis, which is associated with a reduction in prognosis. The prevalence of aortic valve insufficiency also increases with advancing age. Timely causal treatment is crucial in the management of aortic valve diseases. Following the indication for intervention, the heart team plays a central role in evaluating the results and making therapeutic decisions that consider the patient's preferences. In the assessment of treatment options, considerations regarding the long-term perspective are particularly crucial, especially in younger patients. The most common therapeutic approach for aortic valve diseases is the introduction of a new valve prosthesis. In the majority of cases, this is now achieved through catheter-based implantation of a bioprosthetic heart valve, known as transcatheter aortic valve implantation (TAVI). Open surgical aortic valve replacement (AVR) is favored in younger patients with low surgical risk or in the case that TAVI is not feasible. In AVR, both biological and the longest-lasting mechanical prosthesis types are used. Surgical repair techniques are primarily applied in cases of aortic valve regurgitation. Notably, TAVI, as well as surgical procedures for the treatment of aortic valve diseases, have undergone significant advancements in recent years, including expanded indications for TAVI and, on the surgical side, in particular the development of minimally invasive surgical techniques.

Bridging gaps: The urgent call for cardio-obstetrics as a subspecialty in India.

Cardiovascular disease complicates 1-4% of pregnancies. Women with heart disease going through pregnancy are on the increase. While global maternal deaths during pregnancy are decreasing, India remains a significant contributor to maternal deaths in the world. Cardiovascular disease during pregnancy is the leading cause of maternal mortality in developed nations, and this trend is expected soon in India, with the ongoing obstetric transition. Research in developed nations indicates that a high proportion of maternal mortality related to heart disease is preventable. However, India lacks indigenous data, risk stratification tools, management guidelines, and a well-defined cardio-obstetric team concept for pregnant women with heart disease. There is a pressing need to establish national registries, develop risk stratification tools, develop and disseminate management guidelines, and create dedicated cardio-obstetric programs. This article provides a comprehensive overview of this requirement and offers solutions to bridge the existing gaps in India's maternal healthcare landscape.

PCI versus CABG in coronary artery disease.

The evidence basis for percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) in coronary artery disease (CAD) has become more firmly established over the last decade in view of new evidence from several large, randomized trials and propensity-matched registries. In comparison to PCI, CABG offers substantial survival benefits and significant reductions in myocardial infarction and need for repeat revascularization in multivessel disease in patients with intermediate and high severity disease, whereas for left main disease these benefits are largely observed in patients with the highest-severity disease. In general, the benefits of CABG are further enhanced in patients with diabetes and/or impaired ventricular function. In stable or urgent clinical situations most decisions for intervention should be agreed by a multidisciplinary group ('Heart Team'), incorporating the severity of CAD and the patient's overall clinical suitability and personal wishes for any proposed procedure.

When to Consider Coronary Revascularization for Stable Coronary Artery Disease.

Revascularization is an effective adjunct to medical therapy for some patients with chronic coronary disease. Despite numerous randomized trials, there remains significant uncertainty regarding if and how to revascularize many patients. Coronary artery bypass grafting is a class I indication for patients with significant left main stenosis or multivessel disease with ejection fraction ≤ 35%. For other patients, clinicians must carefully consider the potential benefits of symptom improvement and reduction of future myocardial infarction or CV death against the risk and cost of revascularization. Although guidelines provide a framework for these decisions, each individual patient will have distinct coronary anatomy, clinical factors, and preferences.

Implementing Formal Mitral Heart Team Improves Multidisciplinary Evaluation Rate and Survival of Patients With Severe Primary Mitral Regurgitation.

BACKGROUND: Multidisciplinary heart team (HT) evaluation is recommended for patients with severe primary mitral regurgitation to optimize treatment decisions. However, its impact on patient outcomes remains unknown. We evaluated the impact of implementing mitral HT on patient survival. METHODS AND RESULTS: We conducted a retrospective cohort study of patients with new diagnoses of severe primary mitral regurgitation in a large healthcare network echocardiogram database between 2016 and 2020. We compared the incidence of multidisciplinary evaluation by structural cardiology and cardiac surgery services and 2-year survival before and after mitral HT implementation. The 1:1 propensity-score matching between pre- and post-mitral HT used Society of Thoracic Surgeons Predicted Risk of Mortality for mitral repair, age, sex, race, heart failure symptoms, inpatient setting, history of MI, and dementia as covariates. Logistic regression identified variables associated with the likelihood of undergoing multidisciplinary evaluation. Among 70 510 echocardiograms performed, 391 patients had severe primary mitral regurgitation (median age, 77 years; 46% women). Multidisciplinary evaluation increased from 29% to 89% (P<0.001), and intervention increased from 24% to 75% following mitral HT implementation (P<0.001). Among 180 propensity-score matched patients, mortality was lower post-mitral HT at 2 years (19% versus 32%, P=0.04). The multivariable model showed that mitral HT implementation and heart failure symptoms were associated with higher odds of undergoing multidisciplinary evaluation (OR [odds ratio], 18.7 and 2.72, respectively), whereas female sex and older age were associated with lower odds (OR, 0.39 and 0.93, respectively). CONCLUSIONS: Implementation of mitral HT was associated with drastic improvement in multidisciplinary evaluation for patients with severe primary mitral regurgitation. This coincided with higher proportions of patients undergoing mechanical correction of MR and improved overall patient survival.

[Update on the treatment of aortic valve stenosis in symptomatic and asymptomatic patients]. / Update zur Behandlung der Aortenklappenstenose bei symptomatischen und asymptomatischen Patienten.

Aortic valve stenosis is one of the most frequent valvular heart diseases requiring treatment in industrialized countries. The symptom onset is associated with a significantly increased mortality, so that there is a clear indication for treatment in patients with severe, symptomatic aortic valve stenosis; however, data on the optimal treatment of patients with asymptomatic aortic valve stenosis are scarce. Smaller studies in the field of cardiac surgery suggest that early surgical valve replacement is superior to a conservative approach. For this reason, the results of additional adequately powered randomized trials are awaited with great interest. In this year numerous long-term results from randomized comparisons of the two available treatment options (surgical versus transcatheter aortic valve replacement) were published, which will further guide the heart team to find the best treatment approach for each individual.
