Hyperacute Effects of Mitral Transcatheter Edge-to-Edge Repair on Left Ventricular Volumes and Functions.

Transcatheter edge-to-edge repair (TEER) is an effective intervention for high-risk patients with severe symptomatic mitral regurgitation (MR), but its acute impact on left ventricular (LV) function has not been well studied using advanced echocardiographic techniques. This study investigated the immediate effects of TEER on LV volumes and functions, as well as their influence on mid-term outcomes, using high-resolution 3D transesophageal echocardiography. In 80 patients undergoing TEER for severe MR (mean age 79±8 years, 49% with primary MR), LV end-diastolic volume (LVEDV) and stroke volume significantly decreased (161±61 to 147±54 ml and 69±18 to 50±15 ml, respectively), while end-systolic volume increased (92±60 to 97±45 ml; p<0.

Single versus Dual Antiplatelet Therapy after Left Atrial Appendage Closure: a Propensity Score Matching Analysis.

Background: Either dual antiplatelet therapy or oral anticoagulation in combination with aspirin represent recommended treatment regimens following left atrial appendage closure (LAAC). As the majority of patients receiving LAAC have high bleeding risk, less aggressive antithrombotic treatments are needed, such as single antiplatelet therapy.

Objectives: To compare both ischemic and bleeding outcomes in patients receiving single (SAPT) or dual antiplatelet therapy (DAPT) after successful LAAC.

Prognostic Value of Advanced Echocardiography in Patients with Ischemic Heart Disease: A Comprehensive Review.

Cardiovascular (CV) diseases caused 20.5 million deaths in 2021, making up nearly one-third of global mortality. This highlights the need for practical prognostic markers to better classify patients and guide treatment, especially in ischemic heart disease (IHD), which represents one of the leading causes of CV mortality.

Findings from transoesophageal echocardiographic follow-up after mitral transcatheter edge-to-edge repair.

Background: Transoesophageal echocardiography (TOE) provides accurate evaluation of mitral valve (MV) function following mitral transcatheter edge-to-edge repair (M-TEER) and may better detect complications in case of suboptimal result.

Aims: We aimed to evaluate midterm anatomical changes and structural complications after M-TEER using TOE and investigate their association with clinical outcomes at 2 years.

Methods: A follow-up TOE at 6 months was systematically recommended to all patients included in our institutional prospective M-TEER registry until December 2021.

Pericardial Effusion After Left Atrial Appendage Closure: Timing, Predictors, and Clinical Impact.

Background: Pericardial effusion (PE) is the most common serious left atrial appendage closure (LAAC) complication, but its mechanisms, time course, and prognostic impact are poorly understood.

Objectives: This study sought to assess the frequency, timing, predictors and clinical impact of PE after LAAC.

Methods: Data on consecutive patients undergoing percutaneous LAAC between 2009 and 2022 were prospectively collected including the 1-year follow-up.

Acute Heart Failure During the Peripartum Period Due to Aggravated Tricuspid Regurgitation.

Latent valvular heart disease may be aggravated or demasked during pregnancy because of physiologic hemodynamic changes, including higher circulating volume, heart rate, and cardiac index, as well as stress during labor. The presence of valvular heart disease increases the risk of maternal and fetal/newborn adverse events. Early diagnosis, risk assessment, and specific management are crucial.

Hyperoxia-induced deterioration of diastolic function in anaesthetised patients with coronary artery disease - Randomised crossover trial.

Background: There are no current recommendations for oxygen titration in patients with stable coronary artery disease. This study investigates the effect of iatrogenic hyperoxia on cardiac function in patients with coronary artery disease undergoing general anaesthesia.

Methods: Patients scheduled for elective coronary artery bypass graft surgery were prospectively recruited into this randomised crossover clinical trial.

Infectious Endocarditis of a Heterotopic Caval Valved Stent.

Right-sided infective endocarditis (IE) accounts for 5% to 10% of all IE cases. Compared with left-sided IE, it is more often associated with intravenous drug abuse and intracardiac devices, whereas the latter has become more prevalent in recent decades. The authors report the first case of IE in a heterotopic caval valved stent used for treating torrential tricuspid regurgitation.

Hemolysis After Transcatheter Mitral Valve Implantation Resolved by Valve Retensioning.

Transcatheter mitral valve implantation is an emerging technology for the treatment of inoperable or high-risk patients with symptomatic severe mitral regurgitation. Known technical issues are obstruction of the left ventricular outflow tract, paravalvular leakage, and hemolysis. We report a case of valve retensioning successfully resolving paravalvular leakage and hemolysis.

[Myocardial bridging: a contemporary review].

Myocardial bridging, corresponds to an abnormal, usually congenital, anatomical relationship between the myocardium and a coronary vessel. It most commonly affects the left anterior descending coronary artery. Despite technological advances, angiography remains the gold standard diagnostic method with a typical image of systolic compression (milking).

Amplatzer patent foramen ovale occluder: safety and efficacy.

The patent foramen ovale (PFO) is a common anatomical variant in humans (prevalence 25%). Most often asymptomatic, it may engender paradoxically embolic strokes, myocardial infarctions, or visceral or peripheral ischemia. It is causatively related to migraine, positional or exertional hypoxemia with dyspnea, diving incidents, high altitude edema, and sleep apnea.
