OBJECTIVES: Mitral periprosthetic leakage (PPL) is a serious complication following valve replacement. Conflicting outcomes of surgical treatment have been reported in the presence of multiple previous cardiac operations and associated co-pathological conditions. METHODS: Sixty-five symptomatic patients (37 women, mean age 64.8 years) underwent conventional operations at our hospital from 2006 to 2015. Mitral PPL was the leading surgical indication, although associated procedures were included...

BACKGROUND: Neonates with severe forms of Ebstein anomaly present a surgical challenge, and the Starnes operation as single ventricle palliation is highly advocated. Cone reconstruction for tricuspid valvuloplasty (TVP) has become a widely accepted technique, although very few cases of TVP have been reported in neonates. This report describes a surgical strategy for neonatal Ebstein anomaly, with an aim toward biventricular repair. METHODS: Since 2007, 7 neonates or young infants with severe Ebstein anomalies have received TVP at the National Taiwan University Hospital, Taipei, Taiwan...

Rationale: The pathogenesis of bicuspid aortic valve (BAV)-associated aortopathy is poorly understood and no prognostic biomarker is currently available. Objective: We aimed to identify putative circulating biomarkers pathogenetically and prognostically linked to bicuspid aortopathy. Methods and Results: By RT-PCR, we evaluated gene expression variations (versus normal aorta) of transforming growth factor-beta1 (TGF-β1), connective tissue growth factor (CTGF), matrix metalloproteinase-2 (MMP-2), MMP-14, endoglin (ENG) and superoxide dismutase 3 (SOD3) in ascending aorta samples from 50 tricuspid and 70 BAV patients undergoing surgery for aortic stenosis (aorta diameter ≤45mm: BAVnon-dil or >45mm: BAVdil)...

Advancement in imaging techniques and interventional cardiology procedures have generated renewed interest in anatomy of tricuspid valve complex. The purpose of the present study was to characterize the morphology of tricuspid valve leaflets using objective criteria. Thirty-six embalmed cadaveric hearts were utilized for the present study. Leaflet morphology was studied using newly defined criteria. Commissural zones were identified and leaflets were delineated. Presence of scallops was also recorded. Single leaflet was observed in six cases, double in 26 cases, and triple in four cases...

BACKGROUND: In severe right heart obstruction (RHO), redistribution of cardiac output to the left ventricle (LV) is well tolerated by the fetal circulation. Although the same should be true of severely regurgitant tricuspid valve disease (rTVD) with reduced or no output from the right ventricle, affected fetuses more frequently develop hydrops or suffer intrauterine demise. We hypothesized that right atrium (RA) function is altered in rTVD but not in RHO, which could contribute to differences in outcomes...

Papillary fibroelastoma is an uncommon primary cardiac tumor, predominantly associated with left-sided valvular endocardium. Affectation of tricuspid valve leaflets is rare, and management in asymptomatic patients remains controversial. We present a 30-year-old female referred for evaluation prior to bariatric surgery. A routine echocardiogram revealed a mobile cardiac mass attached to the tricuspid valve. A patent foramen ovale was also present. Tumor was surgically removed. Histology confirmed the definite diagnosis of a papillary fibroelastoma...

Tricuspid regurgitation (TR) is commonly encountered in the management of patients with a variety of cardiovascular diseases. Primary TR is the result of structural abnormalities of the valve or chordal attachments whereas functional TR results from alterations in right ventricular (RV) or right atrial (RA) size, shape or function. The vast majority of TR cases seen in practice are functional in nature and usually results from left-sided heart disease (e.g., mitral valve disease, left ventricular (LV) systolic dysfunction) and/or pulmonary vascular disease, though it also manifests in the presence of isolated chronic atrial fibrillation (AF)...
