Mitral insufficiency results from a failure of the valve leaflets to meet during ventricular systole. During exploratory surgery on patients afflicted with this disease, the observation was made by the authors and others1 that the regurgitant jet could be effectively controlled by the surgeon’s index finger with significant improvement in the action of the heart as long as the finger remained a...
Combined transcatheter tricuspid valve replacement and pulmonary is limited to case reports. We reported a of simultaneous transfemoral valve-in-valve procedure using Edwards valves in 36-year-old male patient from the Kingdom Saudi Arabia with history bioprosthetic degeneration. also long-term outcomes this procedure. There are reports for surgical combined (TV) (PV) replacement, but mortality...
Severe aortic insufficiency may accelerate mitral valve closure. We noted this echocardiographic finding in several patients with the acute onset of severe aortic insufficiency. Accordingly, we examined our total echocardiographic series retrospectively for early closure of the mitral valve (ECMV) in the setting of aortic insufficiency and found it in 11 of 53 patients with confirmed aortic ins...
Background: The Ross procedure has been known as a good method for aortic valve replacement. Pulmonary allograft postoperative stenosis subsequent to the Ross procedure has been noted as an important disadvantage of this technique, although risk factors related to this complication are not clearly recognized. In this study we evaluate the risk factors of pulmonary allograft stenosis after Ross ...
BACKGROUND Transannular patch (TAP) repair of tetralogy of Fallot often results in significant right ventricular outflow tract (RVOT) dilation and distortion. We hypothesized that insertion of Melody valves into the proximal right and left branch pulmonary arteries (PAs) would reduce pulmonary regurgitation fraction (PRF) in an ovine model of pulmonary insufficiency and dilated RVOT. METHODS ...
Criteria for selection of patients with aortic valve disease for cardiac catheterization are described, based on a study of 81 cases. Children with aortic stenosis warrant catheterization at the time when the clinical diagnosis is made, but in adults this examination may be deferred until symptoms appear or left ventricular hypertrophy is recognized. In patients with pure aortic insufficiency c...
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...
Abstract Musculoskeletal injuries are the most common reason for surgery in severely injured patients. In addition to direct cardiac damage after physical trauma, there is rising evidence that trauma induces secondary structural and functional damage. Previous research associates hip fractures with appearance of coronary heart disease: As 25% elderly patients developed a major adverse event fra...
OBJECTIVE Mitral valve insufficiency must be treated by repair whenever as possible as it provides better results - especially within the pediatric population in order to avoid valve replacement inconvenients. The aim of this study is to describe mitral valve repair technique based on an anatomical and functional approach. METHODS During a 13 months period, eight children (age ranged from 2 a...
Isolated tricuspid insufficiency can be a well-tolerated lesion, as illustrated by a 32year follow-up in one patient reported here. A second case of recent onset is also described. The 13 reported cases of isolated tricuspid insufficiency due to trauma can be divided into two groups: ruptured papillary muscle or ruptured chordae tendineae and/or valve. All patients with ruptured papillary muscl...
