OBJECTIVES: The effect of performing aortic valve repair in combination with valve-sparing operation on the length of time for which patients are free from reoperation is unclear. The objective of this study was to determine if the performance of aortic valve repair during valve-sparing operation modified the freedom from reoperation time. METHODS: From January 2003 to July 2014, 78 patients ...

Using a 2.2 MHZ directional Doppler ultrasound unit, the instantaneous peak aortic velocity pattern was recorded transcutaneously in 15 normal persons and 15 patients with aortic insufficiency. The transducer was positioned in the suprasternal notch and aimed posteriorly to cross the descending aortic arch at an angle approximately parallel to blood flow. The electrocardiogram, phonocardiogram,...

OBJECTIVE Midterm follow-up is analyzed after the aortic translocation (Nikaidoh) procedure, an alternative to the Rastelli procedure for ventriculoarterial discordance, ventricular septal defect, and pulmonary stenosis. METHODS Nineteen patients underwent a Nikaidoh procedure at a median age of 3.3 years (0.9-9.3 years). The native aortic valve was translocated from the right to the left ven...

The study of patients with aortic insufficiency has revealed that many demonstrate a first degree The possible advantages of this P-R prolongation have only recently been described (Herbert, 1967). It appears that such a mechanism enables the left atrium to contract earlier (relative to ventricular systole) and thus deliver its volume contribution to forward flow before the premature closure of...

EPIDEMIOLOGY Predisposing factors for infective endocarditis are cardiac abnormalities that disrupt the endocardium by means of a jet injury, as well as the presence of blood-borne microorganisms that colonize these abnormal surfaces. Congenitally bicuspid aortic valve is the most common predisposing lesion for endocarditis of the aortic valve. In addition, congenital abnormalities of the aorti...

We describe a successful surgical treatment in a 2.5-year old boy with Loeys-Dietz syndrome, in whom we performed aortic arch and ascending aorta replacement with a valve-sparing operation (VSO) of the aortic root because of significant aortic insufficiency and dilation of the aortic root. We believe that VSO is ideal for treating young patients with aortic root aneurysm with normal or minimall...

The corresponding video is an aortic valve (AV) reimplantation using the Kuban Cuff modification technique (Video 1). The patient is a 36-year-old male with acute (3 days) DeBakey type I aortic dissection. He has Marfan syndrome, aortic root aneurysm of 65 mm, tricuspid aortic valve with aortic grade 3 insufficiency. The patient had a previous abdominal aortic replacement without any other sign...

OBJECTIVE To assess the midterm follow-up of reduction aortoplasty with external wrapping associated with aortic valve replacement in high risk patients. METHODS Six patients with ascending aortic aneurysm and aortic valve disease were included in this study. Four of them were male. The age ranged from 61 to 70 years (mean 65.7 years). One patient presented severe mitral valve insufficiency. ...

To determine whether a ventricular (LV) end-systolic dimension (ESD) > 55 mm and LV left fractional shortening < 25% are risk factors for aortic valve replacement (AVR) in patients with aortic insufficiency, we analyzed the clinical course and M-mode echocardiograms in 47 consecutive patients who underwent AVR for isolated symptomatic Al. Group 1 patients (n = 27) had a preoperative ESD < 55 mm...

a new approach for the assessment of myocardial contractility in aortic and mitral valve disease. Seventy patients underwent diagnostic right and left heart catheterization. Twenty-six patients had aortic stenosis, 18 had aortic insufficiency, and 26 had mitral regurgitation. Patients with aortic stenosis were divided into two groups on the basis of left ventricular mass index<172 g/m2 (AS1) an...
