Tricuspid valve repair with papillary muscle approximation for congenital tricuspid valve regurgitation due to tricuspid valve dysplasia

Abstract

We experienced a case of a 1-year-old female with congenital tricuspid valve regurgitation caused by tricuspid valve dysplasia. The anterior and septal leaflets were particularly dysplastic, and leaflet tethering was observed. The anterior papillary muscle was approximated to the interventricular septum, and a commissural edge-to-edge suture was inserted on the anteroseptal commissure. Tricuspid valve regurgitation improved to be trivial after surgery and has not worsened 1 year later. Papillary muscle approximation could be one of the feasible reparative techniques for congenital tricuspid valve regurgitation.

Discovery and functional investigation of BMP4 as a new causative gene for human congenital heart disease

“…Notably, if minor cardiac developmental aberrations are encompassed, such as patent foramen ovale and aortic bicuspid valve, the prevalence of CHD rises to around 5% of all live births [4][5][6]. As an array of cardiovascular developmental deformations, CHD is clinically categorized into > 30 distinct isoforms, encompassing double-outlet right ventricle (DORV) and ventricular septal defect (VSD) [2,[7][8][9][10][11][12][13][14]. Though certain mild/minor forms of CHD may resolve spontaneously [2], severe/complex forms of CHD usually lead to worse quality of life [15][16][17], reduced exercise performance [18][19][20][21], neurodevelopmental delay and structural brain anomaly [22][23][24][25][26], ischemic/thromboembolic stroke [27,28], acute renal injury/chronic kidney disease [29][30][31][32], hepatic fibrosis [33,34], pulmonary dysplasia/ pulmonary arterial hypertension [35][36][37], bacte-Am J Transl Res 2024;16 (5):2034-2048 rial endocarditis [38][39][40][41][42], chronic heart failure …”
