ABSTRACT
Objective To review the patients with rheumatic tricuspid valve disease ( RTVD) who were confirmed in cardiac operation and underwent tricuspid valve repair ,and summarize two and three-dimensional echocardiography ( 2D-STE ,3D-STE) characteristics of RTVD ,and evaluate the surgical procedures and outcomes of RTVD . Methods Between December 2009 and December 2017 ,359 patients with rheumatic heart disease ( RHD) underwent left-sided valvular replacement were enrolled . During the operation , 56 patients with RTVD were confirmed . All patients underwent 2D-STE and 3D-STE preoperatively . The preoperative echo characteristics of RTVD and the procedure of tricuspid valvular repair were reviewed . The morphology and function of tricuspid valve were followed after operation . Results Fifteen patients with RTVD were diagnosed by transthoracic echocardiography( TTE) preoperatively .Eight patients were presented tricuspid stenosis . Tricuspid annulus diameter [ ( 40 .3 ± 5 .6 ) mm ] , tethering distance[(5.9±2.2)mm] ,andpulmonaryarterysystolicpressure[(46.3±15.9)mmHg(1mmHg=0.133 kPa) ] were measured by echocardiography ,preoperatively . Moderate and severe tricuspid regurgitation were presented in 32 patients( 57 .1％ ) . All patients underwent tricuspid valvular repair . During the mean follow-up (78 .9 months) ,tricuspid annulus diameter was reduced and tricuspid regurgitation was relieved . Recurrent tricuspid regurgitation occurred in 8 patients(14 .3％ ) . Conclusions Preoperatively 2D-STE and 3D-STE need to evaluate tricuspid valve very carefully . Compared with functional tricuspid regurgitation , RTVD has some characteristics ,including more serious tricuspid reflux grade ,higher tethering distance ,the mismatch between tricuspid reflux degree and tricuspid anmular diameter or pulmonary artery pressure . Tricuspid valve repair shows better early and mid-term outcomes .
ABSTRACT
Objective The aim of this study was to summarize the characteristics of rheumatic tricuspid valve disease ( RTVD) and to evaluate the mid-term outcomes in patients undergoing tricuspid valve repair with RTVD. Methods Between January 2009 and June 2016, 251 consecutive patients with rheumatic heart disease( RHD) underwent left-sided valvular re-placement by a single surgeon. We analyzed 39 patients with RTVD which was diagnosed during the operation. Among them, 32 patients, with moderate or higher tricuspid regurgitation( TR) , were compared with other 59 patients of functional tricuspid regurgitation( FTR) for a better understanding of the features of the RTVD. A total of 39 patients were categorized into 2 groups:Ring annuloplasty group(n=33) and non-Ring annuloplasty group(n=6) which consisted of modified De Vega annu-loplasty for 4 patients and edge-to-edge repair for 2. Meanwhile, 13 of them underwent concomitant tricuspid commissurotomy and 1 patient had a tricuspid leaflet augmentation procedure. We analyzed the mid-term outcomes of 22 patients( follow-up du-ration>1 year)with a mean follow-up duration of(45.5 ±25.1) months. Results Compared with FTR, patients with RTVD had higher preoperative TR grade(3.1 ±0.8 vs. 2.6 ±0.7, P=0.004) but with lower preoperative PASP[(53.8 ±19.4) mmHgvs.(63.6±21.5)mmHg,P=0.037)](1mmHg=0.133kPa) andtricuspidannulusdiameter(TAD) thatobserved bothinpreoperativeechocardiogramtests[(37.0±5.7)mmvs.(41.9±6.7)mm,P=0.018)]andintraoperativedetection [(35.6±4.1)mmvs.(39.9±6.5)mm,P=0.000)] . TherewasnoearlymortalityandresidualmoderateorhigherTR grades in either group. Compared with patients in non-ring annuloplasty group, patients in ring annuloplasty group showed low-er postoperative TR grade(0. 2 ± 0. 4 vs. 0. 7 ± 0. 5, P=0. 039) and acceptable TR grade(0. 8 ± 0. 5 vs. 1. 3 ± 1. 9, P>0. 050) during the mid-term follow-up. PASP, the peak diastolic velocity and pressure gradient across tricuspid valve were not different between groups in preoperative, postoperative and follow-up. Conclusion Compared with FTR, Patients with RTVD had lower preoperative PASP and TAD, but with a higher preoperative TR grade. In our study, ring annuloplasty showed simi-lar mid-term outcomes compared with other procedures.
ABSTRACT
Objective To explore determinants of functional tricuspid regurgitation with twodimensional (2D) and three-dimensional (3D) echocardiography,and to provide theoretical basis for surgery treatments.Methods Fifty-six subjects with left-sided valular diseases and tricuspid regurgitation underwent 2D and 3D echocardiography examinations.The tricuspid annulus diameter,the valvular tethering height and right ventricular volume and ejection fraction were measured.Results Based on the degree of tricuspid regurgitation,the patients were grouped into mild regurgitation (group 1) and moderate or more regurgitation (group 2).Comparing the two groups by t test,the tricuspid annulus diameter,the largest distance of tricuspid valvular tethering and the end-diastolic right ventricle volume had significantly enlarged in group 2 ( P ＜0.01 ).And the degrees of tricuspid regurgitation had good correlations with the annulus diameter,the valvular tethering,the right ventricular volume and pulmonary artery systolic pressure.Also,the 3D echocardiography revealed there were some valvular pathologies aggravating regurgitation.Conclusions The degree of functional tricuspid regurgitation is mainly determined by the annulus dilation and pulmonary hypertension.Further more,the 3D echocardiography can give us more details of the valves.
ABSTRACT
Objective To evaluate pulmonary hypertension(PH) and surgical therapeutic effects using radionuclide pulmonary perfusion imaging in patients of valvular heart disease. Methods And material 115 patients accumulated with valvular disease were included from May 2001 to August 2007. Echocardiography and first-pass radionuclide pulmonary perfusion imaging(FPPPI) were performed in all patients before surgery,7days after surgery and 3 months after surgery(33cases). Patients were divided into four groups. Pulmonary artery pressure (PAP) is normal group[mean pulmonary arterial pressure (MPAP)≤20mm Hg(1 mm Hg =0. 133 kPa)]; PAP slightly rise group[20 mm Hg < MPAP≤30 mm Hg]; PAP moderate rise group[30 mm Hg < MPAP≤50 mm Hg]; PAP weighty rise group[MPAP >50 mm Hg]. Results Lung Equilibrium Time (LET)by FPPPI were(18.87 ± 4.80) s, (26. 17 ± 7.09) s, (38.48 ± 7.09) s and (54.59 ± 7.96) s in this four groups before surgery. LET were 17.58 ±4.52, 21.51 ±6.44, 23.94 ±5.85, 27.29 ±6.70 in this four groups 7 days after surgery (P<0.001). There were no siguificantly differences of LET in 33 cases 3 months after surgery compared with those of 7 days after surgery. Conclusion Pulmonary arterial pressure siguificantly decreased 7 days after surgery in patients with PH of valvular heart disease, especially in those of slightly and moderate rise groups. FPPPI is an accuracy method in evaluating surgical therapeutic effects in valvular heart disease.
ABSTRACT
<p><b>OBJECTIVE</b>To describe the diagnosis and surgical management of coronary artery aneurysm.</p><p><b>METHODS</b>Between October 1996 and May 2000, 6 patients with coronary artery aneurysm underwent surgical treatment. Of these patients, 3 had Kawasaki disease and 3 coronary artery fistula. All patients underwent coronary artery bypass grafting. Three patients had aneurysms resected and fistulous ostium closed. One patient received aortic valve replacement.</p><p><b>RESULTS</b>There were no deaths and later death, nor major complications during the hospital stay. The results of follow-up were satisfactory.</p><p><b>CONCLUSIONS</b>Coronary artery aneurysm is rare and its prognosis is poor. Early diagnosis and operation are necessary. The aneurysm should be resected, the coronary artery should be bypassed, and other associated diseases should be treated properly.</p>
