REVIEW
Robert J Lederman, Adam B Greenbaum, Toby Rogers, Jaffar M Khan, Melissa Fusari, Marcus Y Chen
Transcaval access has been used successfully for over 200 transcatheter aortic valve replacements, large-bore percutaneous left ventricular assist devices, and thoracic endovascular aortic aneurysm repairs. This review teaches how to plan transcaval access and closure based on computed tomography. The main planning goals are to: 1) identify calcium-free crossing targets in the abdominal aorta along with optimal fluoroscopic projection angles and level with respect to lumbar vertebrae; 2) identify obstacles such as interposed bowel or pedunculated aortic atheroma; 3) plan covered stent bailout; and 4) identify jeopardized vascular branches such as renal arteries that might be obstructed by bailout covered stents if employed...

Dynamic systolic compression of the coronary arteries is almost always due to the existence of myocardial bridging that is most commonly localized in the middle segment of the left anterior descending coronary artery. However, it has rarely been reported in patients with pericardial adhesions, tumor, foreign body, or pseudoaneurysms. Only rare case reports exist regarding dynamic coronary compression by a dyskinetic left ventricular aneurysm. We present a patient with a myocardial bridge-like systolic compression of the distal left anterior descending caused by postinfarction dyskinetic left ventricular aneurysm...

Aortic valve infective endocarditis (IE) can be complicated with severe aortic regurgitation (AR) jet-related lesions such as vegetations, pseudoaneurysms, aneurysms or perforations on the anterior mitral leaflet. Herein is reported the case of a 69-year-old male with culture-negative aortic valve endocarditis complicated with aortic valve perforations resulting in severe and eccentric AR and an AR jet-related ventricular septal defect (VSD). Neither transthoracic echocardiography (TTE) nor two-dimensional transesophageal echocardiography (2D-TEE) were unable to clearly discriminate an aorto-right ventricular fistula from a VSD...

BACKGROUND: Valve-sparing root replacement (VSRR) is an established therapy for aortic root pathology. Limited insight exists when the results of VSRR are compared with those of conventional root replacement with use of a bioprosthetic composite conduit (BIO). This study compares the operative and midterm results of VSRR and BIO. METHODS: A retrospective review from 2002 to 2015 at a United States academic center identified 282 patients who underwent VSRR and 425 patients who underwent BIO...

BACKGROUND: For coronary interventions the arterial access via the radial artery is associated with fewer vascular access site complications, and has been shown to reduce major bleeding when compared to the femoral approach. But the endomyocardial biopsy (EMB) approach is usually done by a transfemoral or cervical access known to be associated with an increased risk of artery puncture and its potential complications (i.e., false aneurysm, artery-venous fistula) and needs post-procedural immobilization...

BACKGROUND: The aim of the present study was to evaluate the echocardiographic follow-up of patent foramen ovale, which is considered a potential etiological factor in various diseases, and to determine the factors affecting spontaneous closure. METHODS: Between January 2000 and June 2012, records of 918 patients with patent foramen ovale were retrospectively reviewed. Patency of less than 3 mm around the fossa ovalis is called patent foramen ovale. Patients with cyanotic congenital heart diseases, severe heart valve disorders and severe hemodynamic left to right shunts were excluded from the study...

Thoracic aortic aneurysms rupture and dissection are among the most devastating vascular diseases, being characterized by elevated mortality, despite improvements in diagnostic imaging and surgical techniques.An increased aortic root diameter (ARD) represents the main risk factor for thoracic aortic dissection and rupture and for aortic valve regurgitation.Even though arterial hypertension is commonly regarded as a predisposing condition for the development of thoracic aorta aneurysms, the role of blood pressure (BP) as determinant of aortic root enlargement is still controversial...

INTRODUCTION: Thoracic aortic stent grafts are orders of magnitude stiffer than the native aorta. These devices have been associated with acute hypertension, elevated pulse pressure, cardiac remodelling and reduced coronary perfusion. However, a systematic assessment of such cardiovascular effects of thoracic endovascular aortic repair (TEVAR) is missing. The CardiOvascular Remodelling following Endovascular aortic repair (CORE) study aims to (1) quantify cardiovascular remodelling following TEVAR and compare echocardiography against MRI, the reference method; (2) validate computational modelling of cardiovascular haemodynamics following TEVAR using clinical measurements, and virtually assess the impact of more compliant stent grafts on cardiovascular haemodynamics; and (3) investigate diagnostic accuracy of ECG and serum biomarkers for cardiac remodelling compared to MRI...

BACKGROUND: Marfan syndrome (MFS) and familial non-syndromal thoracic aortic aneurysm and dissection (ns-TAAD) are genetic aortopathies causing aortic dilatation with increased aortic stiffness. Left ventricular (LV) contractility and ventricular-vascular coupling index (VVI) were compared between MFS and ns-TAAD and determinants of VVI were investigated. METHODS AND RESULTS: Patients with MFS (M 57, F 47) and ns-TAAD (M 72, F 39) were studied by echocardiography and compared with controls (M 77, F 71)...

Many prospective cohort studies have demonstrated that hypertension is a strong risk factor for total mortality and cardiovascular disease (CVD). Heart disease includes coronary heart disease (CHD), heart failure, atrial fibrillation, valvular disease, sudden cardiac death (SCD), sick sinus syndrome (SSS), cardiomyopathy, and aortic aneurysms. Most of the epidemiologic prospective studies of heart disease focused on coronary/ischemic heart disease. Here we comprehensively reviewed the association between hypertension and the above-mentioned heart diseases...
