Cardiovascular Oncology: The Need for a Multidisciplinary Approach.

Improved cancer survivorship has led to an increase in cardiovascular (CV) complications in the oncologic population, mainly associated with therapeutic regimens. Hence, cardio-oncology has grown toward unifying the cancer care process in which the best prevention, early detection, treatment, and CV surveillance are offered to patients. This multidisciplinary approach allows us to optimize and agree upon clinical decisions to enhance clinical outcomes. Atrial fibrillation is one of the hot topics in the field because it is still challenging in cancer patients. The optimal antithrombotic therapy remains unclear. Nevertheless, evidence supports that specific recommendations are needed due to a hemorrhagic/thrombotic disbalance present within this subgroup of patients and a low rate of anticoagulation treatments compared with the general population. Further, cardiotoxicity management is currently transforming. Increasingly, early detection of subclinical alterations is raising awareness. When medical therapy is initiated early, fewer patients progress to ventricular dysfunction and the rate of patients completing cancer therapy gradually increases. New approaches are demonstrating better outcomes and these strategies will expectedly be established in clinical practice. Cardio-oncology enables us to find the best balance between cancer treatment and CV health protection. Nowadays, more and more physicians are being instructed in this discipline, which gradually exhibits a greater presence in conferences and scientific journals. However, given the need for physicians thoroughly trained in cardio-oncology, this subspecialty must be promoted further.

Safety and Efficacy of the Combination of Sacubitril/Valsartan and SGLT2i in HFrEF Patients (SECSI Registry).

ABSTRACT: Recent studies have proven benefit of SGLT2i drugs in patients with heart failure with reduced ejection fraction (HFrEF), but their safety when combined with angiotensin-neprilysin inhibitor (ARNI) has not been established. The Safety and Efficacy of the Combination of Sacubitril/Valsartan and SGLT2i in HFrEF Patients registry was conducted to address this issue. SECSI registry is a consecutive, observational, retrospective, multicentre study conducted in 3 Heart Failure Units in Spain. It included 144 HFrEF patients who were treated with ARNI and iSGLT2. Data were collected at baseline, month 2, and month 6. The primary endpoint was the estimated glomerular filtration rate (eGFR), after the initiation of ARNI and sodium-glucose cotransporter-2 inhibitors (SGLT2i). Secondary endpoints included potassium levels and functional class (New York Heart Association class). There were 3 prespecified subgroup analyses: Elderly patients (≥70 years), patients with chronic kidney disease (KDIGO classification G3), and the sequence of drug initiation. Mean age was 69.9 ± 10.1 years, and 110 (76.4%) were men. Left ventricular ejection fraction was 32 ± 7.8%, and most patients were symptomatic [123 (87.2%) New York Heart Association II/III/IV]. eGFR decreased at month 2 and this trend was maintained at month 6 [eGFR baseline 68.5 ± 17.3, month 2 62 ± 19.7 and month 6 64.7 ± 8.6 mL/min/1.73 m2 (P < 0.01 for both)]. In prespecified analysis, elder patients and those who simultaneously initiate both treatments showed the steeper decrease in eGFR. To conclude, co-administration of SGLT2i and ARNI in routine care in HFrEF patients produced a slight decrease in eGFR at 6 months of follow-up. This decrease was especially significant in elder patients and those who initiate both drugs simultaneously.

Heart Failure in the Time of COVID-19.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has emerged as a new threat to healthcare systems. In this setting, heart failure units have faced an enormous challenge: taking care of their patients while at the same time avoiding patients' visits to the hospital. OBJECTIVE: The aim of this study was to evaluate the results of a follow-up protocol established in an advanced heart failure unit at a single center in Spain during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: During March and April 2020, a protocolized approach was implemented in our unit to reduce the number of outpatient visits and hospital admissions throughout the maximum COVID-19 spread period. We compared emergency room (ER) visits, hospital admissions, and mortality with those of January and February 2020. RESULTS: When compared to the preceding months, during the COVID pandemic there was a 56.5% reduction in the ER visits and a 46.9% reduction in hospital admissions, without an increase in mortality (9 patients died in both time periods). A total of 18 patients required a visit to the outpatient clinic for decompensation of heart failure or others. CONCLUSION: Our study suggests that implementing an active-surveillance protocol in acutely decompensated heart failure units during the SARS-CoV-2 pandemic can reduce hospital admissions, ER visits and, potentially, viral transmission, in a cohort of especially vulnerable patients.

Sustained Improvement of Left Ventricular Strain following Transcatheter Aortic Valve Replacement.

PURPOSE: Left ventricular (LV) mechanics are impaired in patients with severe aortic stenosis (AS). Transcatheter aortic valve replacement (TAVR) has become a widespread technique for patients with severe AS considered inoperable or high risk for open surgery. This procedure could have a positive impact in LV mechanics. The aim of the study was to evaluate the effect of TAVR on LV function recovery, as assessed by myocardial deformation parameters, both immediately and in the long term. METHODS: One-hundred nineteen consecutive patients (81.2 ± 6.9 years, 50.4% female) from 10 centres in Europe with severe AS who successfully underwent TAVR with either a self-expanding CoreValve (Medtronic, Minneapolis, MN, USA) or a mechanically expanded Lotus valve (Boston Scientific, Natick, MA, USA) were enrolled in a prospective observational study. A complete echocardiographic examination was performed prior to device implantation, before discharge and 1 year after the procedure, including the assessment of LV strain using standard 2D images. RESULTS: Between baseline and discharge, only a modest but statistically significant improvement in GLS (global longitudinal strain) could be seen (GLS% -14.6 ± 5.0 at baseline; -15.7 ± 5.1 at discharge, p = 0.0116), although restricted to patients in the CoreValve group; 1 year after the procedure, a greater improvement in GLS was observed (GLS% -17.1 ± 4.9, p < 0.001), both in the CoreValve and the Lotus groups. CONCLUSIONS: Immediate and sustained improvement in GLS was appreciated after the TAVR procedure. Whether this finding continues to be noted in a more prolonged follow-up and its clinical implications need to be assessed in further studies.

Long-term prognostic value of peak exercise echocardiogram in patients hospitalized with acute chest pain.

INTRODUCTION: Peak exercise echocardiogram (EEcho) has shown reasonable sensitivity and specificity in detecting significant coronary artery disease (CAD). The objective was to evaluate the prognostic value of EEcho in patients hospitalized for acute chest pain (CP) and its additional prognostic information regarding exercise electrocardiogram test (EECG). METHODS: Prospective observational study performed between May 2011 and September 2013, including 250 patients consecutively admitted for acute CP with normal cardiac biomarkers and nondiagnostic electrocardiogram. All patients were prospectively followed for 1 year, and major adverse cardiovascular events (MACE) were recorded: cardiac death, nonfatal myocardial infarction (MI), or angina with coronary revascularization. RESULTS: EEcho was positive in 16%. Patients with positive EEcho had a higher incidence of hypertension and higher TIMI risk score, showing significant CAD in 66%. We observed contradictory results (EECG-EEcho) in 20%. Patients with positive EEcho and negative EECG had significant CAD in the 66%, and patients undergoing coronary angiography with negative EEcho and positive EECG did not show significant coronary artery disease. Only positive EEcho (P<.001, HR 0.169; 95% CI, 0.088-0.250) and atrial fibrillation (P<.025, HR 0.125; 95% CI, 0.016-0.233) were independently associated with MACE during follow-up. In patients with negative EEcho, the presence of MACE was 2%. CONCLUSIONS: EEcho in patients hospitalized for acute chest pain presents good ability to diagnose acute coronary syndrome, while providing additional information when combined with an EECG in up to 20% of cases. Moreover, a negative EEcho in this cohort seems to provide prognostic information beyond the acute event to predict long-term MACE.

Clinical Experience with Ivabradine in Acute Heart Failure.

OBJECTIVE: Ivabradine has been shown to improve symptoms and to reduce rehospitalization and mortality in patients with severe chronic heart failure (HF). Its indication in acute HF is not clear. Acute HF patients could also benefit from HR reduction, as myocardial consumption and oxidative stress are related to tachycardia. Moreover, beta-blockers are contraindicated in cardiogenic shock and should not be initiated with congestive signs. Accordingly, we evaluated the role of ivabradine in acute HF patients. METHODS: This was a retrospective analysis of 29 consecutive patients treated for acute HF in the Cardiac ICU, and for whom ivabradine was initiated during hospitalization between January 2011 and January 2014. All patients were in sinus rhythm and had a heart rate (HR) >70 bpm. Catecholamine use was necessary in 16 patients (57.1%) during the hospitalization, in 14 (87.5%) of these before ivabradine treatment. RESULTS: Systolic blood pressure showed no variation during the first 24 h of ivabradine administration or at discharge. HR showed an absolute reduction of 10 bpm at 6 h (p < 0.001), 11 bpm at 24 h (p = 0.004) and 19 bpm (p < 0.001) at discharge. No episodes of significant bradycardia or hypotension were recorded after starting the drug. CONCLUSIONS: HR reduction with ivabradine in acute HF is well tolerated. It represents an attractive option, especially when there is excessive catecholamine-related tachycardia; this should be appropriately evaluated in randomized trials.

Wireless Ultrasound Guidance for Femoral Venous Cannulation in Electrophysiology: Impact on Safety, Efficacy, and Procedural Delay.

BACKGROUND: Ultrasound (US) guidance increases safety and efficacy in vascular cannulation and is considered the standard of care. However, barriers including workflow interference and the need to be assisted by a second operator limit its adoption in clinical routine. The use of wireless US (WUS) may overcome these barriers. The aim of this study was to assess the impact of a novel WUS probe during its initial implantation in an electrophysiology (EP) laboratory. METHODS: Thirty-six patients requiring femoral venous cannulation for EP procedures were included in this single center, prospective, observational study, comparing WUS guidance with the anatomical landmark approach. The primary endpoint was time to successful cannulation. Secondary endpoints included rate of unsuccessful punctures, accidental arterial punctures, and workflow interference. RESULTS: Compared with anatomical landmark approach, WUS guidance significantly reduced mean time to successful cannulation (87.3 ± 94.3 vs 238.1 ± 294.7 seconds, P < 0.01). Workflow interference was predominantly nonexistent or mild and decreased after the first three weeks of use. In addition, WUS guidance improved safety and efficacy, reducing the rate of accidental arterial punctures (0.02 ± 0.1 vs 0.25 ± 0.5 arterial punctures per cannulation, P < 0.05) and unsuccessful attempts (0.26 ± 0.8 vs 1.75 ± 2.1 attempts per cannulation, P < 0.01). CONCLUSIONS: WUS guidance resulted in faster, safer, and more effective femoral venous cannulation than the anatomical landmark approach without adding significant workflow interference. The application of wireless technology in this setting contributed to overcoming some of the barriers preventing a more widespread clinical use of US guidance.

Left ventricular vortices as observed by vector flow mapping: main determinants and their relation to left ventricular filling.

BACKGROUND: Swirling flow, organized in vortices, contributes to adequate left ventricular function. In this study, we apply a novel echocardiographic flow-mapping technique, vector flow mapping (VFM), to evaluate the main characteristics of left ventricular vortices and its relation to filling parameters. METHODS: Forty-eight subjects underwent conventional transthoracic echocardiographic examination with additional intracardiac flow assessment with VFM using a Aloka Alpha-10 system and experimental VFM analysis software. To analyze vortex behavior, its rotation direction, duration, location inside the left ventricle, size, and intensity were assessed in apical long-axis view. Its relation to conventional left ventricular filling parameters was then analyzed. RESULTS: Two vortex components were consistently identified following each transmitral filling wave. The anterior component of these visualized vortices was analyzed, due to its higher significance in the cardiac cycle, following early filling (V1) and atrial contraction (V2). Differences were observed in several aspects of vortex behavior between V1 and V2, particularly in patients with normal left ventricular filling parameters. These differences may be related to varying roles of vortices in different periods of the cardiac cycle. CONCLUSIONS: Vector flow mapping allowed visualization and measurement of several parameters defining vortex behavior inside the cardiac cycle. The differences observed in these parameters between vortices in different phases of the cardiac cycle may be related to their role in optimizing cardiac function.

Guidance of treatment of perivalvular prosthetic leaks.

Percutaneous closure of paravalvular leaks has grown into becoming a widely considered option for treatment of hemodynamically significant regurgitation in patients with valve prosthesis. Guidance provided by the use of cardiovascular imaging techniques before and during the intervention has proved its relevance to improve accuracy and, with it, the outcome of the procedure. It has also been essential in the successful evolution of the technique and the development of devices specifically designed for it. The present work reviews the role of imaging before, during and after treatment of perivalvular prosthetic leaks and the most recent and significant advances in it.

How to improve patient outcomes following TAVI in 2024? Recent advances.

Transcatheter aortic valve implantation (TAVI) has revolutionized the treatment of aortic stenosis, particularly among elderly patients. The world's first TAVI procedure was performed in 2002 by Professor Cribier. It was approved for clinical use in Europe in 2007, followed by approval in the United States in 2011. It has since been introduced into clinical practice throughout Europe, and there has been a remarkable increase both in the number of procedures and in the number of centers performing TAVI. Recent findings endorse its additional application in lower-risk populations, suggesting a transformative shift in the field of interventional cardiology. This review article thoroughly explores the recent advances and key considerations aimed at enhancing patient outcomes following TAVI. Key areas of focus include valve durability, paravalvular leak management, valve-in-valve procedures, and the implications and management of coronary artery disease in these patients. We highlight the importance of selecting valves with favorable hemodynamics, minimal coronary risk, and optimal durability, especially for younger, lower-risk patients. Paravalvular leak remains a significant concern; thus, pre-procedural planning and immediate corrective measures are crucial to mitigate its impact. The increasing need for valve-in-valve interventions underscores the importance of the strategic initial valve choice with a forward-looking perspective. Additionally, emerging strategies such as transcatheter leaflet laceration to prevent coronary obstruction during reinterventions, are examined. This review synthesizes current research and clinical practice, providing a roadmap for enhancing TAVI outcomes through technological advances and strategic procedural planning. The findings and recommendations presented aim to optimize long-term patient prognosis, ensuring that TAVI remains a leading solution for aortic stenosis in an increasing variety of patients.

Right Bundle Branch Block Predicts Appropriate Implantable Cardioverter Defibrillator Therapies in Patients with Non-Ischemic Dilated Cardiomyopathy and a Prophylactic Implantable Cardioverter Defibrillator.

Background: The benefit of prophylactic implantable cardioverter defibrillators (ICDs) in patients with severe systolic dysfunction of non-ischemic origin is still unclear, and the identification of patients at risk for sudden cardiac death remains a major challenge. Aims/Methods: We retrospectively reviewed all consecutive patients with non-ischemic dilated cardiomyopathy (NICM) who underwent prophylactic ICD implantation between 2008 and 2020 in two tertiary centers. Our main goal was to identify the predictors of appropriate ICD therapies (anti-tachycardia pacing [ATP] and/or shocks) in this cohort of patients. Results: A total of 224 patients were included. After a median follow-up of 51 months, 61 patients (27.2%) required appropriate ICD therapies. Patients with appropriate ICD therapies were more frequently men (87% vs. 69%, p = 0.006), of younger age (59 years, (53-65) vs. 64 years, (57-70); p = 0.02), showed more right bundle branch blocks (RBBBs) (15% vs. 4%, p = 0.007) and less left bundle branch blocks (LBBBs) (26% vs. 47%, p = 0.005) in the ECG, and had higher left ventricular end-diastolic (100 mL/m2, (90-117) vs. 86, (71-110); p = 0.011) and systolic volumes (72 mL/m2, (59-87) vs. 61, (47-81), p = 0.05). In a multivariate competing-risks regression analysis, RBBB (HR 2.26, CI 95% 1.02-4.98, p = 0.043) was identified as an independent predictor of appropriate ICD therapies. Conclusion: RBBBs may help to identify patients with NICM at high risk of ventricular arrhythmias and requiring ICD intervention.

Case Series of Ventricular Tachycardia Ablation With Pulsed-Field Ablation: Pushing Technology Further (Into the Ventricle).

Three cases of ventricular tachycardia ablation with pulsed-field ablation technology performed at 2 separate centers are reported, highlighting the advantages and disadvantages of this tool inside the ventricle: its dependence on proximity rather than contact makes it useful in sites with poor stability, while the speed of application and large scope of action provided by commercially available catheters could help with ablating large diseased areas of endocardium in a fast and hemodynamically well-tolerated fashion. However, lesion depth could be insufficient for guaranteeing efficacy in preventing ventricular tachycardias originating at an epicardial site, even in the right ventricle.

Conduction system pacing and atrioventricular node ablation in heart failure: The PACE-FIB study design.

AIMS: Atrial fibrillation (AF) worsens the prognosis of patients with heart failure (HF). Successful treatments are still very scarce for those with permanent AF and preserved (HFpEF) or mildly reduced (HFmrEF) ejection fraction. In this study, the long-term benefits and safety profile of heart rate regularization through left-bundle branch pacing (LBBP) and atrioventricular node ablation (AVNA) will be explored in comparison with pharmacological rate-control strategy. METHODS AND RESULTS: The PACE-FIB trial is a multicentre, prospective, open-label, randomized (1:1) clinical study that will take place between March 2022 and February 2027. A total of 334 patients with HFpEF/HFmrEF and permanent AF will receive either LBBP followed by AVNA (intervention arm) or optimal pharmacological treatment for heart rate control according to European guideline recommendations (control arm). All patients will be followed up for a minimum of 36 months. The primary outcome measure will be the composite of all-cause mortality, HF hospitalization, and worsening HF at 36 months. Other secondary efficacy and safety outcome measures such as echocardiographic parameters, functional status, and treatment-related adverse events, among others, will be analysed too. CONCLUSION: LBBP is a promising stimulation mode that may foster the clinical benefit of heart rate regularization through AV node ablation compared with pharmacological rate control. This is the first randomized trial specifically addressing the long-term efficacy and safety of this pace-and-ablate strategy in patients with HFpEF/HFmrEF and permanent AF.

Impact of power and contact force on index-guided radiofrequency lesions in an ex vivo porcine heart model.

PURPOSE: Lesion size index (LSI) and ablation index (AI) are markers of lesion quality that incorporate power, contact force (CF) and time in a weighted formula to estimate lesion size. Although accurate predicting lesion depth in vitro, their precision in lesion size estimation has not been well established for certain power and CF settings. We conducted an experimental ex vivo study to analyse the effect of power and CF in size and morphology of ablation lesions in a porcine heart model. METHODS: Twenty-four sets of 10 perpendicular epicardial radiofrequency applications were performed with two commercially available catheters (TactiCath, Sensor Enabled; and SmartTouch) on porcine left ventricle submerged in 37 °C saline, combining different power (25, 30, 35, 40, 50 and 60 W) and CF (10 and 20 g) settings, and aiming at a lower (LSI/AI of 5/400) or higher (LSI/AI of 6/550) index. After each application, lesions were cross-sectioned and measured. RESULTS: Four hundred eighty lesions were performed. For a given target index and CF, significant differences in lesion volume and depth with different power were observed with both catheters, generally with smaller lesions using higher power. Lesions performed with CF of 10 g were particularly smaller with TactiCath compared to SmartTouch; lesions with CF of 20 g aiming a low LSI/AI were, however, bigger; lesions with CF of 20 g aiming a high LSI/AI were similar. In general, high-power lesions were wider and shallower than low-power lesions, especially with SmartTouch. CONCLUSION: Size and morphology of index-guided radiofrequency lesions varied significantly with different power and CF settings.

Value of advanced interatrial block in the diagnosis of the ischemic stroke's aetiology: A cohort study.

INTRODUCTION AND OBJECTIVES: Advanced interatrial block has been linked with atrial fibrillation (AF) (Bayes syndrome). On the other hand, the aetiology of the stroke remains unknown in approximately 20-25% of patients admitted due to ischaemic stroke. The aim of this study was to evaluate whether advanced interatrial block and CHADS2-VASC scale is linked to AF in patients admitted due to ischaemic stroke without previous AF history. METHODS: A prospective analysis of consecutive in-hospital patients admitted with ischemic stroke between January/2018 and April/2019 in a stroke hospital was performed. Patients had to be in sinus rhythm at admission and without previous history of AF/atrial flutter. During follow up patients receive the usual care. RESULTS: A total of 236 patients were included. The median follow-up was 540 days (407-695). 19 patients (8.1%) had advanced interatrial block at admission. Advanced interatrial block was associated with the diagnosis of AF during follow up (5 (26.3%) Vs 21 (9.7%) p=0.027). A CHADS2-VASC score>4 at admission was also associated with AF diagnosis during follow up (23(14.6%) vs 3(3.9%) p=0.009). CONCLUSION: This study confirms the association of advanced interatrial block and CHADS2-VASC>4 at admission with the diagnosis of AF during follow up in patients with ischemic stroke. This association could have important implications in patients with ischemic stroke who present advanced interatrial block and without previous history of AF.

Role of sex on the efficacy of pharmacological and non-pharmacological treatment of heart failure with reduced ejection fraction: A systematic review.

Background: Heart Failure (HF) is a growing epidemic with a similar prevalence in men and women. However, women have historically been underrepresented in clinical trials, leading to uneven evidence regarding the benefit of guideline-directed medical therapy (GDMT). This review aims to outline the sex differences in the efficacy of pharmacological and non-pharmacological treatment of HF with reduced ejection fraction (HFrEF). Methods and results: We conducted a systematic review via Medline from inception to 31 January 2022, including all randomized clinical trials published in English including adult patients suffering HFrEF that reported data on the efficacy of each drug. Baseline clinical characteristics, primary outcomes, and sex-specific effects are summarized in tables. The systemic review has been conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. In total, 29 articles were included in the systematic review. We observed that the proportion of women enrolled in clinical trials was generally low, the absence of a prespecified analysis of efficacy by sex was frequent, and the level of quality of evidence on the efficacy of GDMT and implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy (CRT-) in women was relatively poor. Conclusions: Sex influences the response to treatment of patients suffering from HFrEF. All the results from the landmark randomized clinical trials are based on study populations composed mainly of men. Further studies specifically designed considering sex differences are warranted to elucidate if GDMT and new devices are equally effective in both sexes.

Case report: From monkeypox pharyngitis to myopericarditis and atypical skin lesions.

Background: A global outbreak of the human monkeypox virus (HMPXV), first identified in May 2022, was declared a health emergency of international concern on 23 July 2022. Before the global outbreak, monkeypox cases were mostly confined to central and west African countries, where this virus is prevalent. Close contact, mainly sexual contact, is supposed to be the main route of transmission, and it is remarkable that the incidence is higher in men who have sexual relationships with other men. Case summary: A 40-year-old Caucasian man arrived at the emergency department complaining of oppressive epigastric pain extending to the chest after a diagnosis of pharyngitis, which was suspected to be caused by the human monkeypox virus. Based on the clinical symptoms, physical examination, serum cardiac biomarkers, and electrocardiographic findings, he was diagnosed with myopericarditis. The real-time PCR for human monkeypox in skin lesions, urine, plasma, and the oropharyngeal swab was positive. The peak of troponin I was 20.6 ng/ml, and the electrocardiogram showed an upward concavity in the ST segment in diffuse leads, which was in agreement with the previous diagnosis. The presence of edema, subepicardial, and myocardial late gadolinium enhancement, and increased values on T1 mapping in the cardiac MRI were in agreement with the diagnosis of myopericarditis. Antiviral treatment with tecovirimat was started with excellent tolerability. After 6 days, the patient recovered and was discharged. Discussion: To our knowledge, this is one of the first reported cases of myopericarditis due to human monkeypox infection, which was confirmed by a cardiac MRI following modified Lake Louise criteria. The short span between the onset of the mucocutaneous symptoms and the myocardial damage suggests a pathogenic association. Furthermore, the active viral replication in plasma samples and the negative results on real-time PCR for other viruses support this clinical association.

Optimal surgical timing after post-infarction ventricular septal rupture.

BACKGROUND: Ventricular septal rupture (VSR) following acute myocardial infarction (AMI) is a dangerous condition. Surgical VSR closure is the definitive therapy, but there is controversy regarding the surgical timing and the bridging therapy between diagnosis and intervention. The objective of this study is to analyze the ideal time of surgical repair and to establish the contribution of mechanical circulatory support (MCS) devices on the prognosis. METHODS: We designed an observational, retrospective, multicenter study, selecting all consecutive patients with post-AMI VSR between January 1, 2008 and December 31, 2018, with non-exclusion criteria. The main objective of this study was to analyze the optimal timing for surgical repair of post-AMI VSR. Secondary endpoints were to determine which factors could influence mortality in the patients of the surgical group. RESULTS: A total of 141 patients were included. We identified lower mortality rates with an odds ratio of 0.3 (0.1-0.9) in patients operated on from day 4 compared with the surgical mortality in the first 24 hours after VSR diagnosis. The use of MCS was more frequent in patients treated with surgery, particularly for intra-aortic balloon pump (IABP; 79.6% vs. 37.8%, p < 0.001), but also for veno-arterial extracorporeal membrane oxygenation (VA-ECMO; 18.2% vs. 6.4%, p = 0.134). Total mortality was 91.5% for conservative management and 52.3% with surgical repair (p < 0.001). CONCLUSIONS: In our study, we observed that the lowest mortality rates in patients with surgical repair of post-AMI VSR were observed in patients operated on from day 4 after diagnosis of VSR, compared to earlier interventions.

The Role of 2D and 3D Echo in Mitral Stenosis.

Mitral stenosis is an important cause of heart valve disease globally. Echocardiography is the main imaging modality used to diagnose and assess the severity and hemodynamic consequences of mitral stenosis as well as valve morphology. Transthoracic echocardiography (TTE) is sufficient for the management of most patients. The focus of this review is the role of current two-dimensional (2D) and three-dimensional (3D) echocardiographic imaging for the evaluation of mitral stenosis.
