BACKGROUND The heart adapts to the volume overload of aortic regurgitation with dilation and hypertrophy. The development of left ventricular hypertrophy at the protein level is a dynamic process resulting from an imbalance between cardiac protein synthesis and degradation. The objective of the present study was to determine in vivo the relative contributions of cardiac protein synthesis and de...

We report successful mitral valve repair in a patient with porcelain aorta, complicated by aortic regurgitation, severe cerebrovascular disease, and multiple cerebral infarctions. The patient was a 77-year-old male who had congestive heart failure as a result of severe mitral regurgitation. Mitral valve repair was performed without aortic cross-clamping, using moderate hypothermic cardiopulmona...

Between June 1969 and August I970, 8o patients, aged 22 to 63 years, had lone aortic valve replacement with frame-mounted autologous fascia lata. The operative mortality was 3.8 per cent. Seventy-seven survivors have been followed for 3 to 4 years and 50 have had postoperative investigation. There have been 8 subsequent deaths, 3 from infective endocarditis, 4 from aortic regurgitation, and one...

An account of aortic regurgitation complicating ankylosing spondylitis is given. Twenty patients with lone aortic regurgitation and without overt spondylitis were examined clinically and radiologically and tissue typed. No evidence of sacroiliitis could be found in any patient. HLA B27 was absent from this group, and no significant disturbance in antigen frequency was noted.

The hemodynamic and clinical data of 42 patients with chronic significant aortic regurgitation and 31 normal subjects were examined. Of the patients with aortic regurgitation, 28 had a third heart sound (S3) gallop and 14 did not. There was no significant difference in the severity of regurgitation between the patients with or without an S3 gallop. However, all patients with an S3 gallop had an...

BACKGROUND The CoreValve US High-Risk Clinical Study compared clinical outcomes and serial echocardiographic findings in patients with severe aortic valve stenosis after transcatheter aortic valve replacement (TAVR) with a self-expanding bioprosthesis or surgical aortic valve replacement (SAVR). METHODS AND RESULTS Eligible patients were randomly assigned 1:1 to TAVR with a self-expanding bio...

Takayasu's arteritis is a rare inflammatory aortoarteritis of unknown etiology and causes stenoocclusive disease of the aorta and its branches as well as aortic regurgitation. A surgical case of Takayasu's arteritis is presented. A 56-year-old female exhibited aortic regurgitation complicated by severe coarctation of the thoracoabdominal aorta due to Takayasu's arteritis. In this case, a 2-stag...

This case highlights the clinical usefulness of three-dimensional (3D) echocardiography. The diagnosis of inter-ventricular septal defect associated with aortic regurgitation has been performed in a 50-year-old man using 3D echocardiography. This advanced echocardiography could accurately reproduce the anatomy of the defect and provide further insights in the mechanisms of aortic regurgitation ...
