BACKGROUND The proximal acceleration flow region is a laminar flow field that is located immediately upstream from the leaking orifice. The purpose of this study was to evaluate whether cinemagnetic resonance imaging can provide information regarding the proximal acceleration flow region in patients with aortic regurgitation and to analyze the relation between the area of the proximal accelerat...

There are certain aortic root pathologies where only one or two of the aortic sinuses are diseased. We aimed to evaluate our mid-term results after a partial remodeling of the aortic root. A total of 220 patients underwent a valve-sparing operation at our institution. In 29 patients (mean age: 62+/-10 years), two (n=22) or one (n=7) native aortic sinuses were preserved. Operative indication was...

there is a paucity of literature regarding iatrogenic aortic valve perforation after cardiac operation is performed in the vicinity of the aortic valve. this report describes the clinical, echocardiographic, and angiocardiographic recognition of iatrogenic aortic valve perforation in a patient who had previously under gone membranous ventricular septal defect and pulmonary stenosis. five days a...

BACKGROUND Repair of prolapsed aortic valve leaflets has been considered a challenging technique for cardiac surgeons. In this paper we describe our surgical approach, "the chordae technique." It consists of the correction of aortic cusp prolapse by shortening the free margin length and of an adjustment of the leaflets coaptation height by anchoring the prolapsing cusp to the aortic wall at the...

To determine whether left ventricular (LV) end systole and end ejection uncouple in patients with long-term mitral regurgitation, 59 patients (22 control patients with atypical chest pain, 21 patients with aortic regurgitation, and 16 patients with mitral regurgitation) were studied with micromanometer LV catheters and radionuclide angiograms. End systole was defined as the time of occurrence (...

OBJECTIVES Aortic valvuloplasty could represent an alternative to valve replacement resulting in optimal haemodynamic conditions, avoiding anticoagulation and allowing, in young people, normal aortic annulus growth. We analysed our results of aortic valve repair for incompetence due to leaflets and root pathology. METHODS From January 2003 to January 2013, 235 patients affected by aortic valv...

BACKGROUND Acute aortic syndrome is the modern term that includes aortic dissection, intramural hematoma, and symptomatic aortic ulcer. Iatrogenic coronary artery dissection extending to the aorta during percutaneous coronary intervention is a very rare but life-threatening complication. Despite some reports of spontaneous recovery, most of these patients are treated surgically as a spontaneous...

To the Editor: I read with interest the contribution by Cai et al in the “Images in Cardiovascular Medicine” section of the journal.1 They described a patient who developed severe aortic regurgitation and a mitral valve aneurysm 1 month after successful treatment of Streptococcus mitis endocarditis. The case presentation and the title implied that the mitral valve aneurysm was caused by the eff...

The patterns of aortic and tricuspid valve motion in 50 patients with mitral valve prolapse were analyzed by wide-angle, phased-array, two-dimensional echocardiography. Twelve patients (24%) had redundant aortic leaflets bulging into the left ventricular outflow tract during diastole. Eight of 12 patients had aortic regurgitation and seven of 12 had M-mode echocardiographic evidence of aortic v...
