Impact of mechanical circulatory support on outcomes in Takotsubo syndrome complicated by cardiogenic shock: Insights from the RETAKO registry.

Background: Cardiogenic shock (CS) complicates Takotsubo syndrome (TTS), significantly affecting patient outcomes. Since avoiding catecholamines, particularly inotropic agents, is recommended in TTS, temporary mechanical circulatory support (MCS) shows promise as a bridge to recovery. However, there is no prospective data on its use in TTS.

Recovery of Left Ventricular Function and Long-Term Outcomes in Patients With Takotsubo Syndrome.

Background: Takotsubo syndrome (TTS) is a form of transient left ventricular (LV) dysfunction that usually resolves within days to weeks.

Objectives: We aimed to assess the predictors and prognostic impact of time-to-LV recovery after TTS.

Methods: Prospective serial imaging data from the nationwide, multicenter RETAKO (REgistry on TAKOtsubo Syndrome) were comprehensively reviewed to assess the timing of LV recovery.

Renal impairment and outcome in Takotsubo syndrome: Insights from a national multicentric cohort.

Introduction: Data on the association between kidney function and Takotsubo syndrome (TTS) outcomes are scarce and conflictive.

Objective: To assess the impact of chronic kidney disease (CKD) and acute renal failure (ARF) in patients with TTS.

Material And Methods: Patients from the prospective nation-wide (RETAKO) registry were included and divided into quartiles of maximum creatinine (Cr) level during hospitalization.

Pediatric takotsubo cardiomyopathy: A review and insights from a National Multicentric Registry.

Takotsubo syndrome (TTS) in the pediatric population is an infrequent but relevant cause of morbidity and mortality, with limited studies addressing its clinical course and prognosis. We aimed to analyze the clinical features and prognosis of pediatric TTS in a nation-wide multicenter registry and considering the published literature. We included a total of 54 patients from 4 different hospitals in Spain, as well as pediatric TTS patients from the published literature.

Improvement in electrocardiographic parameters of repolarization related to sudden death in patients with ventricular dysfunction and left bundle branch block after cardiac resynchronization through His bundle pacing.

Background: Cardiac resynchronization therapy (CRT) through permanent His bundle pacing (p-HBP) normalizes interventricular conduction disorders and QRS. Similarly, there are immediate and long-term changes in repolarization, which could be prognostic of a lower risk of sudden death (SD) at follow-up. We aimed to compare the changes in different electrocardiographic (ECG) repolarization parameters related to the risk of SD before and after CRT through p-HBP.

His bundle pacing success and electrical parameter stability regardless of three-dimensional transthoracic echocardiography lead localization.

Background Or Purpose: His bundle pacing (HBP) is the most physiological form of ventricular pacing. Few prospective studies have analyzed lead localization using imaging techniques and its relationship with electrical parameters and capture patterns. The objective of this study is to examine the correlation between electrical parameters and lead localization using three-dimensional transthoracic echocardiography (3D TTE).
