Echocardiographic evaluation of the cardiopulmonary unit is difficult in case of tricuspid regurgitation (TR) and combined echocardiographic parameters could be useful. This study aimed to assess the variation of simple and combined echocardiographic parameters analysing the cardiopulmonary unit according to the severity of TR. TR was graded according to Hahn's classification in 179 patients.

Article Synopsis
  • Transthyretin amyloid cardiomyopathy (ATTR-CM) can complicate conditions like heart failure and aortic stenosis (AS), especially in older adults, but its prevalence among AS patients undergoing transaortic valve implantation (TAVI) is not well-studied.
  • A study screening 100 TAVI patients showed an ATTR-CM prevalence of 7%, predominantly in older males, with specific electrocardiographic and structural heart changes noted in those positive for ATTR-CM.
  • One-year survival rates for patients with positive ATTR-CM tests were similar to those with isolated AS, emphasizing the need for ongoing monitoring and further research on long-term outcomes in ATTR-CM patients post-TAVI.

Article Synopsis
  • The study investigated the use of transoesophageal echocardiography (TEE) in elderly patients (≥75 years) with infective endocarditis (IE) and its effects on their treatment and mortality rates.
  • It found that older patients who did not undergo TEE had worse overall health, fewer surgeries indicated, and higher mortality rates, despite having similar IE characteristics compared to those who had TEE.
  • The research highlights the importance of TEE in accurately diagnosing cardiac lesions and improving management, suggesting that underdiagnosis in older patients could lead to poorer outcomes.

(1) Background: Receiving the first internal electric shock is a turning point for patients with an implantable cardioverter defibrillator (ICD) for primary prevention. However, no study has investigated whether patients who receive a first device-delivered electric shock have a poor prognosis even at the time of ICD implantation. (2) Methods: We retrospectively identified 55 patients with ischemic (n = 31) or dilated (n = 24) cardiomyopathy who underwent ICD implantation for primary prevention with exercise test at the time of implantation.

Introduction: Coronary heart disease is the leading cause of morbidity and mortality in nonagenarians, whose numbers have doubled in twenty years. In the absence of recommendations, the place of coronary invasive strategy in this population remains a therapeutic challenge and its interest as well as its risks are poorly established. The aim of our study was to evaluate the safety of coronary invasive practice in the nonagenarian population for all indications.

Background: Transcarotid and trans-subclavian access routes are increasingly used as alternative approaches for transcatheter aortic valve implantation (TAVI) when transfemoral access is not suitable. However, concerns remain about the risk of periprocedural stroke and long-term outcomes following transcarotid/trans-subclavian TAVI.

Aims: The present study sought to compare early and long-term outcomes of transcarotid/trans-subclavian TAVI versus transfemoral TAVI after propensity-score matching.

Background: Transcatheter aortic valve replacement is now indicated in patients at intermediate surgical risk and will probably soon be indicated in patients at low surgical risk, for whom the occurrence of serious procedural complications is not acceptable.

Aims: We aimed to investigate whether simple arterial variables from computed tomography scanning can predict the occurrence of severe early complications in patients undergoing transfemoral TAVR.

Methods: All patients with symptomatic severe aortic stenosis treated by transfemoral transcatheter aortic valve replacement in our centre, and for whom computed tomography images were available, were included.

Transcatheter aortic valve implantation (TAVI) is currently becoming an alternative to surgical valve replacement for patients at low risk, a population that is likely to experience an increase in the radiation-induced cancer risk following TAVI. We aimed to evaluate the overall exposure to ionizing radiation in patients who underwent transfemoral TAVI, including the procedure itself as well as the procedures performed in the preintervention work-up and the post-TAVI interventions. All patients who underwent transfemoral TAVI for symptomatic aortic stenosis in our center over a 26 months period were included.

Patients who underwent radiofrequency ablation of atrial fibrillation are exposed to X-rays not only during the procedure but also during the preprocedural computed tomography. No study has investigated the cumulative effective dose received by patients who underwent atrial fibrillation ablation and identified factors influencing this dose. We aimed to evaluate the overall exposure to ionizing radiation in patients who underwent radiofrequency ablation of atrial fibrillation.

Interventional cardiologists count among the health professionals that are most exposed to ionising radiation. To minimise exposure, it is recommended that the patient be placed at the maximum distance possible from the X-ray source, but this recommendation has not been clinically validated. We aimed to investigate the impact of the average table height on the level of radiation delivered to cardiologists performing coronary interventions.

Objectives: The aim was to describe the impact of infective endocarditis (IE) on functional, cognitive and nutritional statuses, and to estimate the influence of these parameters on surgical management and mortality.

Method: This was a prospective study over 13 months in 14 French hospitals, including patients ≥75 years of age with definite or possible IE. A comprehensive geriatric assessment (CGA) was performed during the first week of hospitalization, including a retrospective estimation of functional status 2 months before hospitalization, and 3 months after.

Cardiologists are among the health professionals that are most exposed to ionizing radiation, but there is no recent study quantifying overexposure of physicians during cardiac resynchronisation therapy (CRT) procedures compared to 'classical' implantation of pacemakers (PMs) or implantable cardioverter-defibrillators (ICDs). We aimed to measure and compare operator exposure to radiation during implantation of PM and ICD with or without CRT. The study population comprised all PMs and ICDs implanted in a large referral centre over a six months period.

Exposure of operators to ionising radiation in interventional cardiology has likely diminished, but data confirming the magnitude of the reduction are lacking. The aim of this study was to compare the dose of radiation received by interventional cardiology operators at 11 years interval (2006 vs 2017). The study population comprised all interventional coronary procedures performed by a single operator in one catheterization laboratory (cathlab) of a large university hospital in north-eastern France.

Congestion is one of the main predictors of poor patient outcome in patients with heart failure. However, congestion is difficult to assess, especially when symptoms are mild. Although numerous clinical scores, imaging tools, and biological tests are available to assist physicians in ascertaining and quantifying congestion, not all are appropriate for use in all stages of patient management.

Technological progress has made it possible to reduce the dose of radiation delivered by medical x-ray systems. In parallel, interventional coronary procedures have become increasingly complex and consequently, last longer. This study aimed to compare the estimated dose of radiation received by patients in interventional cardiology at 10 years interval (2006 vs 2016).
