Long-term outcomes of cardiogenic shock and cardiac arrest complicating ST-elevation myocardial infarction according to timing of occurrence.

Aims: Cardiogenic shock (CS) and cardiac arrest (CA) are serious complications in ST-elevation myocardial infarction (STEMI) patients, with lack of long-term data according to their timing of occurrence. This study sought to determine the incidence and relationship between the timing of occurrence and prognostic impact of CS and CA complicating STEMI in the long-term follow-up.

Methods And Results: We conducted a retrospective analysis of consecutive STEMI patients treated between 2004 and 2017.

Retrospective analysis of percutaneous intervention of the renal artery in transplanted kidneys in children and adolescents at a tertiary public hospital.

Background: This study evaluated the long-term effects of percutaneous intervention in children and adolescents with transplant renal artery stenosis (TRAS).

Methods: Twenty patients had significant stenosis (>50%) and underwent percutaneous transluminal angioplasty (PTA/stenting) (TRAS group-intervention); 14 TNS (non-significant group -control) patients did not have significant stenosis (≤50%) and were treated clinically. The combined primary endpoints were death from all causes and late graft failure.

Percutaneous Strategies in Structural Heart Diseases: Focus on Chronic Heart Failure.

Background: Central Illustration : Percutaneous Strategies in Structural Heart Diseases: Focus on Chronic Heart Failure Transcatheter devices for monitoring and treating advanced chronic heart failure patients. PA: pulmonary artery; LA: left atrium; AFR: atrial flow regulator; TASS: Transcatheter Atrial Shunt System; VNS: vagus nerve stimulation; BAT: baroreceptor activation therapy; RDN: renal sympathetic denervation; F: approval by the American regulatory agency (FDA); E: approval by the European regulatory agency (CE Mark).

Background: Innovations in devices during the last decade contributed to enhanced diagnosis and treatment of patients with cardiac insufficiency.

Impact of periprocedural myocardial injury after transcatheter aortic valve implantation on long-term mortality: a meta-analysis of Kaplan-Meier derived individual patient data.

Background: Periprocedural myocardial injury (PPMI) frequently occurs after transcatheter aortic valve implantation (TAVI), although its impact on long-term mortality is uncertain.

Methods: We performed a pooled analysis of Kaplan-Meier-derived individual patient data to compare survival in patients with and without PPMI after TAVI. Flexible parametric models with B-splines and landmark analyses were used to determine PPMI prognostic value.

B-type natriuretic peptide and N-terminal Pro-B-type natriuretic peptide in severe aortic stenosis: a comprehensive literature review.

B-type natriuretic peptide (BNP) and N-terminal pro-BNP (NT-pro BNP) are cardiac biomarkers that are released in response to increased ventricular and atrial wall stress. Aortic stenosis (AS) leads to hemodynamic changes and left ventricular hypertrophy and may be associated with natriuretic peptide levels. Several studies have shown that increased natriuretic peptide levels are correlated with AS severity and can predict the need for intervention.

Risk factors of transplant renal artery stenosis in kidney transplant recipients.

Background: Transplant Renal Artery Stenosis (TRAS) is a recognized vascular complication after kidney transplantation. The overall risk predictors of TRAS are poorly understood.

Methods: Retrospective analysis of patients with suspected TRAS (Doppler ultrasound PSV > 200 cm/s) who underwent angiographic study in a single center between 2007 and 2014.

Post-Endomyocardial Biopsy Fistula Between Left Anterior Descending Artery and Right Ventricle.

The image in this vignette helps to illustrate a rare, albeit reported, complication of endomyocardial biopsy. The case was discussed by the heart team. Fistula occlusion with microcoils was considered; however, the patient was asymptomatic and presented no reduction of left ventricular ejection fraction, and the documented ischemia was minor.

Long-term clinical outcomes of patients with nonsignificant transplanted renal artery stenosis.

Background: Transplant renal artery stenosis (TRAS) is the main vascular complication of kidney transplantation. For research and treatment purposes, several authors consider critical renal artery stenosis to be greater than 50%, and percutaneous intervention is indicated in this scenario. However, there are no reports in the current literature on the evolution of patients with less than 50% stenosis.

Delayed left main coronary obstruction following transfemoral inovare transcatheter aortic valve replacement: A challenging case.

Coronary obstruction is an uncommon and severe complication after a transcatheter aortic valve replacement (TAVR), that occurs during the procedure in the vast majority of patients. In the present case even in the absence of classic risk factors, an acute coronary syndrome occurred one day after TAVR. Selective angiography revealed a severe left main ostium obstruction by the bulky native leaflet calcification.
