Exploring the Effects of Local Air Pollution on Popliteal Artery Aneurysms.

A growing body of evidence highlights the effects of air pollution on chronic and acute cardiovascular diseases, such as associations between PM and several cardiovascular events. However, evidence of the impact of fine air pollutants on the development and progression of peripheral arterial aneurysms is not available. Data were obtained from the multicenter PAA outcome registry POPART and the German Environment Agency.

Deciphering Popliteal Artery Aneurysm Patient Diversity: Insights From a Cluster Analysis of the POPART Registry.

Background: Popliteal artery aneurysms (PAAs) are the most common peripheral aneurysm. However, due to its rarity, the cumulative body of evidence regarding patient patterns, treatment strategies, and perioperative outcomes is limited. This analysis aims to investigate distinct phenotypical patient profiles and associated treatment and outcomes in patients with a PAA by performing an unsupervised clustering analysis of the POPART (Practice of Popliteal Artery Aneurysm Repair and Therapy) registry.

ACURATE neo2 Transcatheter aortic valve implantation without balloon aortic valvuloplasty - direct ACURATE neo2.

Background: Chronic coronary syndrome (CCS) is a potentially progressive clinical presentation of coronary artery disease (CAD). Clinical practice guidelines (CPGs) are available for prevention, diagnosis, and treatment. Embedded in the "ENLIGHT-KHK" healthcare project, a qualitative study was conducted to identify factors that influence guideline adherence from the perspective of general practitioners (GPs) and cardiologists (CA) in the ambulatory care sector in Germany.

Methods for assessing guideline adherence for invasive procedures in the care of chronic coronary artery disease: a scoping review.

Objectives: In the care of coronary artery disease (CAD), evidence questions the adequate application of guidelines for cardiovascular procedures, particularly coronary angiographies (CA) and myocardial revascularisation. This review aims to examine how care providers' guideline adherence for CA and myocardial revascularisation in the care of chronic CAD was assessed in the literature.

Design: Scoping review.

Health economic consequences of optimal vs. observed guideline adherence of coronary angiography in patients with suspected obstructive stable coronary artery in Germany: a microsimulation model.

Aims: While the number of patients with stable coronary artery disease (SCAD) is similar across European countries, Germany has the highest per capita volume of coronary angiographies (CA). This study evaluated the health economic consequences of guideline-non-adherent use of CA in patients with SCAD.

Methods And Results: As part of the ENLIGHT-KHK trial, a prospective observational study, this microsimulation model compared the number of major adverse cardiac events (MACE) and the costs of real-world use of CA with those of (assumed) complete guideline-adherent use (according to the German National Disease Management Guideline 2019).

Outcomes in Patients With Early Menopause Who Underwent Transcatheter Aortic Valve Implantation.

We sought to investigate the prevalence and impact of early menopause on clinical outcomes in patients who underwent transcatheter aortic valve implantation (TAVI) for severe symptomatic AS. Women's International TAVI is a multinational, prospective, observational registry of women who underwent TAVI for severe symptomatic AS (n = 1,019).

Safety of transesophageal echocardiography during transcatheter edge-to-edge tricuspid valve repair: A single-center experience.

Objectives: We aimed to determine transesophageal echocardiography (TEE) related complications during Transcatheter edge-to-edge tricuspid valve repair (TTVR).

Background: Transesophageal echocardiography is essential to guide structural heart disease (SHD) interventions. TTVR has become an evolving procedure for high-risk patients not suitable for surgery.

A deep neural network using audio files for detection of aortic stenosis.

Background: Although aortic stenosis (AS) is the most common valvular heart disease in the western world, many affected patients remain undiagnosed. Auscultation is a readily available screening tool for AS. However, it requires a high level of professional expertise.

A spear to the heart-the accidental discovery of a giant cement embolism in the right heart: a case report.

Background: The incidence of recognized cardiopulmonary cement embolism in the context of percutaneous vertebroplasty varies between 0% and 23%. In most cases, only small fragments embolize in the pulmonary arteries or the right heart cavities. The latter can cause potential harm by right ventricular perforation.

Sixteen healthy and resistance-trained young (age, 22.1±2.

Atypical and rare cause of myocardial infarction: coronary subclavian steal syndrome (CSSS) treated by a carotid-subclavian bypass in a 71-year-old female patient.

Background: The coronary subclavian steal syndrome (CSSS) is a rare complication after coronary arterial bypass graft operations (CABG) using the left or right internal mammary artery ((L/R)IMA). It results from a retrograde blood flow from the IMA into the subclavian artery (SA) due to a stenosis or occlusion of the SA proximal to the IMA origin. This "steal phenomenon" leads to a decreased blood flow in the IMA and may result in myocardial ischemia (MIS) and even myocardial infarction (MIN).

Association of QRS-T angle and Late Gadolinium Enhancement in patients with a Clinical Suspicion of Myocarditis.

To investigate the association of a wide QRS-T angle on the surface ECG and late gadolinium enhancement on contrast-enhanced cardiovascular magnetic (CMR) imaging in patients with clinically suspected myocarditis. Diagnosis and risk stratification in patients with suspected myocarditis is particularly challenging due to a great spectrum of clinical presentations. Late gadolinium enhancement (LGE) visualizes myocardial necrosis and fibrosis in patients with biopsy-proven myocarditis.

The predictive value of intraprocedural mitral gradient for outcomes after MitraClip and its peri-interventional dynamics.

Background: The current data on the impact of the increased mitral gradient (MG) on outcomes are ambiguous, and intraprocedural assessment of MG can be challenging. Therefore, we aimed to evaluate (a) peri-interventional dynamics of MG, (b) the impact of intraprocedural MG on clinical outcomes, and (c) predictors for unfavorable MG values after MitraClip.

Methods: We prospectively included patients who underwent MitraClip.

QRS-T angle in patients with Hypertrophic Cardiomyopathy - A comparison with Cardiac Magnetic Resonance Imaging.

We sought to investigate the possible association of a wide QRS-T angle on the surface EKG and myocardial fibrosis on contrast-enhanced cardiovascular magnetic (CMR) imaging in patients with hypertrophic cardiomyopathy (HCM). Risk stratification in HCM patients is challenging. Late gadolinium enhancement (LGE) visualizes myocardial fibrosis with unique spatial resolution and is a strong and independent prognosticator in these patients.

QRS-T-angle in Patients with ST-Segment Elevation Myocardial Infarction (STEMI) - a Comparison with Cardiac Magnetic Resonance Imaging.

: The QRS-T angle from the surface EKG is a promising prognostic marker in patients with coronary artery disease. Cardiovascular magnetic resonance (CMR) imaging with late gadolinium enhancement (LGE) offers high resolution imaging of myocardial damage. We investigated the association of the QRS-T angle and the extent of myocardial damage as assessed by LGE in patients with acute ST-segment myocardial infarction (STEMI) : 169 patients with STEMI obtained a standardized digital 12-lead EKG on admission for the calculation of the QRS-T angle and underwent CMR imaging for analysis of infarct size by LGE within the first week.

Drug-Coated Balloon Angioplasty Versus Drug-Eluting Stent Implantation in Patients With Coronary Stent Restenosis.

Background: In patients with coronary in-stent restenosis (ISR) requiring reintervention, it is unclear if the choice of treatment should depend on whether the restenotic stent was a bare-metal stent (BMS) or a drug-eluting stent (DES).

Objectives: This study aimed to assess the comparative efficacy and safety of the 2 most frequently used treatments - angioplasty with drug-coated balloon (DCB) and repeat stenting DES - in patients with BMS-and DES-ISR.

Methods: The DAEDALUS (Difference in Antirestenotic Effectiveness of Drug-Eluting Stent and Drug-Coated Balloon Angioplasty for the Occurrence of Coronary In-Stent Restenosis) study was a pooled analysis of individual patient data from all 10 existing randomized clinical trials comparing DCB angioplasty with repeat DES implantation for the treatment of coronary ISR.

Intraoperative use of transit time flow measurement improves patency of newly created radiocephalic arteriovenous fistulas in patients requiring hemodialysis.

Background: The autologous arteriovenous fistula is the primary choice to establish hemodialysis access without high failure rates. Intraoperative ultrasound flow measurements of newly created autologous arteriovenous fistulas represent a possibility of quality control and may therefore be a tool to assess their functionality. The aim of our study was to correlate intraoperative blood flow with access patency.
