Valvoplasty

BACKGROUND: The morphology of ventricular septal defects (VSDs) that are doubly committed and juxtaarterial places the patient at risk for aortic valvar prolapse and aortic valvar insufficiency (AI). Surgical repair of this type of defect often involves placing sutures through the base of one or more of the leaflets of the pulmonary valve, raising concern for late pulmonary valvar insufficiency (PI). The purpose of this review was to analyze the postoperative follow-up relating to potential late complications with the aortic and pulmonary valves...

OBJECTIVES: The pulmonary valve (PV) annulus is routinely measured angiographically in PV stenosis prior to balloon dilation. We sought to establish whether this radiation exposure is justified, or whether echocardiographic measurements prior to the procedure are sufficient to guide balloon selection. BACKGROUND: Previous studies have found a strong correlation between echocardiographic and angiographic measurements of the PV annulus. However, error of measurement and its implication for procedural practice has not been explored...

Percutaneous balloon mitral valvoplasty (PBMV) has become the treatment of choice for severe pliable rheumatic mitral stenosis. The multi-track system is a recent variation of the double-balloon technique and is easier owing to the use of a monorail balloon and a simple, single-guidewire approach. In the present study, we used the double-coil Inoue metal wire with a multi-track balloon instead of the conventional multi-track wire. We studied 62 consecutive patients (55 females) with significant symptomatic rheumatic mitral valve stenosis who underwent multi-track PBMV...

BACKGROUND: The long-term outcome of modified Fontan operation concomitant with a valve operation for atrioventricular valve (AVV) regurgitation is not well described. METHODS: Between 1977 and 2003, 500 children who underwent modified Fontan operation were subdivided into 192 with AVV plasty (group P) and 308 without AVV plasty (group N). Factors associated with patient outcome were investigated retrospectively. RESULTS: Surgical techniques to correct valve incompetence included circular annuloplasty, partial annuloplasty with Kaye-Reed methods, edge-to-edge repair methods, and valvoplasty, which were combined according to the etiology of the valve lesion...

A 59-year-old woman with chest discomfort was transferred to our hospital. Echocardiography was suggestive of multiple papillary fibroelastoma (PFE). Tumors on both the left and right coronary cusps were confirmed macroscopically and pathologically and a small tumor was noted microscopically on the non-coronary cusp. Aortic valve replacement was successfully performed. The treatment and recurrence rate of PFE is controversial due to its rarity. Given that multiple tumors were seen in the present case and that possible recurrence has been reported elsewhere, valve replacement may be a better choice for surgical repair than valvoplasty in some cases, such as a single PFE in which plasty may be difficult or multiple PFEs regardless of impaired valve function...

OBJECTIVES: The purpose of this study was to evaluate the impact of moderate-or-less functional tricuspid regurgitation (TR) treatment on the clinical outcome of patients with mitral valve (MV) surgery. METHODS: From October 2001 to January 2005, 167 patients in our hospital with MV surgery and without organic tricuspid valve (TV) disease or pulmonary hypertension (PH) showed moderate-or-less functional TR preoperatively, and 41.9% of these patients were treated with TR (group T), compared with 58...

OBJECTIVE: To explore the potential causes and the optimal treatments of recurrent venous ulceration of lower limbs after initial operation. METHODS: Data of patients admitted between January 2000 and June 2010 for recurrent ulceration in lower limbs after previous operation were retrospectively analyzed. Altogether 81 limbs in 73 patients were recruited. There were 55 male patients (60 limbs) and 18 female patients (21 limbs). The average age was 52.6 years (ranging from 31 to 73 years)...

With the use of the superior transseptal approach during mitral valve surgery, good exposure of the mitral valve can be achieved with simple traction sutures, which minimize the risk of deformation of the mitral valve. For this reason, we routinely perform mitral valvoplasty using the superior transseptal approach; however, we, occasionally encounter cases that develop postoperative atrial dysrhythmia. We have therefore, devised a very simple technique for preservation of the sinus node artery in the superior transseptal approach, which is effective for reducing the incidence of postoperative sinus node dysfunction...

BACKGROUND: The reconstruction of the right ventricular outflow tract (RVOT) in congenital heart disease has attracted the interest of cardiac surgeons determined to alleviate the anatomic obstruction and restore RV function. METHODS: From June 1991 to September 2008, 203 consecutive patients (mean, 3.0 years; range, 2 months to 35 years) underwent operations. These patients were classified into 5 groups: group 1, tetralogy of Fallot with pulmonary hypoplasia (144 cases, 70...

Granulicatella adiacens is a nutritionally variant streptococci. Only 3 cases of vertebral osteomyelitis due to these microorganisms have been reported. We experienced a 73-year-old male who consulted us due to fever and back pain of about 1-month duration. On examination, a presystolic murmur was heard in the apical region. Echocardiography showed prolapse of the mitral valve, but no vegetation was observed. MRI revealed osteomyelitis of lumbar vertebrae. As G. adiacens was detected in blood culture, it was determined as the cause of vertebral osteomyelitis, and combination antibiotics therapy was started...

BACKGROUND AND AIM OF THE STUDY: To date, the natural history of the unicuspid aortic valve (UAV) has been poorly described in the literature. To study the association between UAV with associated cardiac and extracardiac abnormalities, a systematic review was conducted. METHODS: A computerized search was conducted of the medical literature published between 1st January 1966 and 1st September 2008, using the databases MEDLINE, EMBASE, Web of Science and Cochrane database...

OBJECTIVE: The aortic valve replacement is a routine procedure with acceptable risk, but in some cases, such a risk can justify contraindication. The minimally invasive transcatheter aortic valve implantation has been viable, with lower morbidity and mortality. The aim of this study was to develop a national catheter-mounted aortic bioprosthesis for the aortic position implant. METHODS: After animal studies, 14 patients with high EuroSCORE underwent transcatheter aortic valve implantation...

This study aimed to examine the definition and indications for surgery, to elucidate the morphologic substrate of aortic regurgitation, and to extrapolate the pathologic mechanisms of subpulmonary stenosis in Eisenmenger ventricular septal defect (EVSD). The study enrolled 160 patients. Preoperative respiratory symptoms and poor growth were present in 41 patients (26%), and 21 patients (13%) required mechanical ventilation. Perimembranous ventricular septal defect (pVSD) had been diagnosed previously for 136 of the patients (85%) at other institutions...

We report a 64-year-old male patient with papillary fibroelastoma of the tricuspid valve associated with moderate mitral regurgitation. Echocardiography had revealed a 10 x 10 mm tumor attaching to the anterior tricuspid leaflet 3 years before. Because the tumor was enlarged to 19 x 15 mm, we excised it with a part of the anterior tricuspid leaflet, and performed tricuspid and mitral valvoplasty. The histological findings suggested papillary fibroelastoma. The postoperative course was uneventful.

On an infant with critical valvular aortic stenosis balloon-valvoplasty, and 3 years later because of the aortic valve regurgitation Ross operation was performed. In the early postoperative period an aortic-root abscess occurred due to an infective endocarditis; the aortic root was corrected by homograft implantation. Due to a relatively small, calcified aortic valve, with aortic valve regurgitation grade III at the age of 12 years, a Bentall-Konno procedure was performed successfully. This is the first case when this complex surgical procedure was performed successfully on a child in Hungary...

Isolated congenital tricuspid regurgitation without downward displacement of the leaflet is uncommon in adults, and repair of such valves often requires a procedure that is more complex than simple tricuspid annuloplasty. We describe a technique of tricuspid valvoplasty using the neo-papillary loop technique to reconstruct multiple artificial chords for isolated congenital tricuspid regurgitation associated with a dysplastic anterior leaflet with agenesis of the chordae tendineae and a hypoplastic anterior papillary muscle...

BACKGROUND: The analysis of immediate and long-term results of mitral valvoplasty by balloon catheter (MVRBC) are still lacking in literature, mainly in the national context. OBJECTIVE: To assess the immediate and late results of patients submitted to mitral valve repair by balloon catheter. METHOD: A total of 330 consecutive patients were followed-up by 47 +/- 36 months (up to 126 months). Univariate and multivariate analyses assessed the factors associated with the success of the procedure, restenosis and late events (death or necessity of new intervention on mitral valve)...
