Temporal trends in postinfarction ventricular septal rupture: the CIVIAM Registry

2020

Abstract Introduction and objectives Postinfarction ventricular septal rupture is a rare but severe complication of myocardial infarction with high mortality rates. Our goal was to analyze which factors could have an impact on mortality due to this entity over the past decade, including those related to mechanical circulatory support . Methods The CIVIAM registry is an observational, retrospective, multicenter study carried out in Spain. We designed a comparative analysis, focused on description of in-hospital management and in-hospital and 1-year total mortality as the primary endpoints, dividing the total observation time into 2 equal temporal periods (January 2008 to June2013 and July 20…

Biodegradable polymer-coated thin strut sirolimus- -eluting stent versus durable polymer-coated everolimus-eluting stent in the diabetic population.

2021

Background: The number of patients with diabetes mellitus (DM) presenting with coronary artery disease is increasing and accounts for more than 30% of patients undergoing percutaneous coronary interventions (PCI). The biodegradable polymer drug-eluting stents were developed to improve vascular healing. It was sought herein, to determine 1-year clinical follow-up in patients with DM treated with the thin strut biodegradable polymer-coated sirolimus-eluting stent (BP-SES) versus durable coating everolimus-eluting stent (DP-EES). Methods: Patients were retrospectively analyzed with DM were treated with either a BP-SES (ALEX™, Balton, Poland, n = 670) or a DP-EES (XIENCE™, Abbott, USA, n = 884)…

Patient selection, echocardiographic screening and treatment strategies for interventional tricuspid repair using the edge-to-edge repair technique

2018

Severe tricuspid regurgitation (TR) has long been neglected despite its well-known association with mortality. While surgical mortality rates remain high in isolated tricuspid valve surgery, interventional TR repair is rapidly evolving as an alternative to cardiac surgery in selected patients at high surgical risk. Currently, interventional edge-to-edge repair is the most frequently applied technique for TR repair even though a device has not been developed for this particular indication. Due to the inherent differences in tricuspid and mitral valve anatomy and pathology, percutaneous repair of the tricuspid valve is challenging due to a variety of factors including the complexity and varia…

A rare case of infrarenal aortic coarctation in a young female

2020

Abstract Introduction Infrarenal abdominal aortic coarctation (AAC) is an extremely rare disease. It can be associated with renal artery stenosis determining secondary renal hypertension. Presentation of case We report a case of AAC in young female patient presenting systemic hypertension non-responder to medical treatment. Diagnostics revealed the involvement of the right renal artery as the cause of hypertension. The management consisted of percutaneous renal artery stenting and close surveillance for the aortic segment. The treatment was uneventful with resolution of the hypertensive condition. Discussion AAC etiology is unknown. There are no studies comparing the long-term treatment out…

Fully percutaneous insertion and removal of the Impella CP via a subclavian approach

2020

The Impella (Abiomed) is a mechanical circulatory support device which augments cardiac output, but may also unload a left ventricle during venoarterial extracorporeal membrane oxygenation (ECMO) [1]. However, the Impella requires an access to a large artery and this may be problematic in a severe peripheral arterial disease. The presented case demonstrates how to insert and remove the Impella CP via a subclavian approach without surgical cutting.

Resistance of the internal mammary artery to restenosis: a histomorphologic study of various porcine arteries.

2007

<i>Background/Aims:</i> Restenosis after percutaneous transluminal angioplasty (PTA) of the internal mammary artery (IMA) grafts is much less pronounced than in other arteries and venous grafts. The aim of the study was to test whether various arteries respond differently to dilatation. <i>Methods:</i> PTA of the IMA, carotid, renal and circumflex coronary (RCx) arteries was performed in 9 pigs (balloon to artery ratio of 1:1.5). After 8 weeks, angiography was repeated and vessels prepared for histological analysis. Immunohistochemical staining was done to examine proliferative activity (Ki67) and to identify the vasa vasorum of the adventitia (F VIII-RA). <i>R…

ABSORB everolimus-eluting bioresorbable vascular scaffold systems for the sealing of unstable plaques

2013

Purpose: We set out to investigate the outcome of patients receiving an Absorb bioresorbable vascular scaffold system in the setting of acute coronary syndromes. Background: Everolimus-eluting bioresorbable vascular scaffold systems have recently been introduced in the market for the treatment of coronary artery stenoses. Experience on the use of these devices is limited to type A lesions in elective settings. Treatment of ruptured plaques with bioresorbable scaffold systems might have the advantage to promote the formation of new fibrotic tissue (plaque sealing) without the disadvantages of permanent metal stent implantation. Methods and results: 64 culprit lesions in 63 patients (age 57±1…

Das Verhalten der Kollateralen bei der perkutanen transluminalen Angioplastie

1990

The fate of 106 collaterals was investigated following percutaneous transluminal dilatation of 113 stenoses and occlusions. Following dilatation, 78% of collaterals were unchanged and 22% could no longer be demonstrated. The success of the dilatation had no bearing on the fate of the collaterals. Collaterals beginning or ending in a dilated portion of vessel disappeared more frequently (30%) than the others (11%). Following five dilatations, some vessels were demonstrated in the area of stenosis, which had not been demonstrated previously. Evidently local events, such as displacement of arteriosclerotic plaques may lead to occlusion or reopening of vessels. Remaining collaterals may be of g…

TCT-282 Risk Factors Associated with Adverse Events during Chronic Total Occlusion Percutaneous Coronary Interventions: A sub-Analysis of the OPEN-CT…

2016

Coronary chronic total occlusions (CTOs) are prevalent and the development of the hybrid approach to CTO PCI has been associated with increased technical success rates. However, the incidence and predictors of adverse events (AEs) during CTO PCI remains poorly defined. We analyzed baseline patient
