ABSTRACT

@#Conventional transcatheter aortic valve replacement is normally recommended with transthoracic echocardiography, and contrast agent mediated fluoroscopy under anesthesia to guide a better implantation of the transcatheter valve. However, iodine-containing contrast agent possibly damages the patient’s kidney, and even induces the acute kidney injury. We reported a 75-year-old patient diagnosed with severe aortic valve stenosis, moderate regurgitation, and chronic renal failure. We performed the aortic valve replacement under the guidance of fluoroscopy and transesophageal ultrasound without contrast agent. Seven days after surgery, the patient recovered well and discharged with alleviated aortic stenosis and fixed transcatheter aortic valve.

ABSTRACT

@#Objective    To investigate the early clinical results of MitraClip system in domestic patients. Methods     We retrospectively analyzed the clinical data of 36 patients who underwent transcatheter edge-to-edge repair procedure using MitraClip system in Beijing Fuwai Hospital, Shenzhen Fuwai Hospital and Fuwai Yunnan Cardiovascular Hospital between January and June 2021. There were 24 males and 12 females, with a median age of 70 (47-86) years. Ten (27.8%) patients had 3+ mitral regurgitation (MR) and 26 (72.2%) patients had 4+ MR preoperatively. Results    All procedures were successfully performed. The reduction in MR was 2+ at least immediately after surgery, and 91.7% of patients had MR≤2+ at 3 days postoperatively. There was no statistical difference in left ventricular ejection fraction change postoperatively. Forward velocity and peak gradient of mitral valve were increased after the procedure. Mean gradient of mitral valve were increased at 3 days postoperatively than immediately after surgery (P<0.001). Two patients had acute pericardial effusion intraoperatively, and received pericardial puncture and drainage immediately. Conclusion    MitraClip system has been applied well in domestic patients and can significantly improve MR. This sutdy has a good consistency with foreign studies, and the early results are satisfactory.

ABSTRACT

@#Objective    To explore the key points, indications and safety of trans-jugular transcatheter closure of atrial septal defect (ASD) in infants. Methods    The clinical data of 53 infants with ASD from January 2017 to May 2019 in our hospital were retrospectively reviewed. There were 20 males and 33 females with the age of 1.2 (0.5-2.9) years, and body weight of 9.0 (6.8-10.6) kg. The ASD diameter was 9.8 (8.0-14.0) mm. Thirty-one patients were treated under the guidance of transesophageal ultrasound (TEE), and the other 22 patients under the guidance of transthoracic echocardiography (TTE). We used the steerable curved sheath through the internal jugular vein under the guidance of echocardiography, and the average occluder size was 13.5±4.5 mm. Results    All of the 53 patients were successfully occluded, and none of them changed to radiation-guided or transthoracic surgery. Postoperative hospital stay was 3.35±0.70 d. There was no complication such as peripheral vascular injury, occluder malposition or displacement, serious arrhythmia or pericardial effusion. The patients were followed up for 14.3±5.1 months without arrhythmia, residual shunt, occluder malposition or displacement or thrombus. Conclusion    Echocardiography-guided trans-jugular closure of ASD for infants with low weight and large ASD shunt or patients with inferior vena cava abnormalities not suitable for femoral vein treatment, not only overcomes the radiation risk of radiation guidance, but also maintains the advantages of minimal invasiveness and safety, providing a new treatment option for such patients.

ABSTRACT

Objective@#To investigate the safety and efficacy of percutaneous intervention of children with combined congenital heart abnormality solely guided by transthoracic echocardiography (TTE) .@*Methods@#From September 2015 to June 2017, 21 children with combined congenital heart abnormality undergoing percutaneous interventional guided by TTE in Fuwai hospital were enrolled in our study, and the clinical data were retrospective analyzed. The atrial septal defect(ASD) closure, ventricular septal defect(VSD) closure, patent ductus arteriosus(PDA) closure or balloon pulmonary valvuloplasty were performed under the guidance of TTE. The procedural effect was evaluated by TTE after operation. The patients were followed up after discharged from the hospital.@*Results@#The age was (37.3±11.6) months, and there were 9 male and 12 female patients. There were 4 cases with ASD and VSD, 6 cases with VSD and PDA, 6 cases with ASD and PDA, 2 cases with VSD and pulmonary stenosis, 3 cases with ASD and pulmonary stenosis. The operations were successfully performed in all patients. No one required extra X ray guidance or open heart surgery. The operation time was (44.6±7.5)min. All patients did not require blood transfusion, inotropic support, and analgesia. There were no complications such as peripheral vascular injury and pericardialeffusion after the operation. The length of hospital stay time was (3.5±0.6) days. All patients were recovered well. The follow-up was (17.6±5.2) months, and post-procedural conduction disturbances, residual shunts, occlude fall off, thrombosis, and new onset of valvular regurgitation were not observed in these patients.@*Conclusion@#Percutaneous interventional of children with combined congenital heart abnormality solely guided by TTE is safe and effective, and the procedure can avoid the potential injuries of X ray and contrast agent.

ABSTRACT

Objective To investigate the efficacy and safety of percutaneous induced thrombosis closure on small patent ductus arteriosus (PDA) solely under echocardiography guidance.Methods From June 2013 to September 2016,276 PDA patients were treated by femoral artery retrograde approach under echocardiography guidance.Twenty-five patients (14 boys,11 girls) among them with small PDA received percutaneous induced thrombosis closure because the delivery sheath could not pass PDA,with mean age (3.7 ± 1.6) years,mean body weight (16.6 ±5.4) kg and the mean diameter of the most narrow PDA was (1.3 ± 0.4) mm.All patients were assessed by transthoracic echocardiography,chest radiography and electrocardiography preoperatively.The intraoperative and postoperative effects were evaluated by echocardiography.Outpatient assessment was performed at 1,3,6 and 12 months after operation with electrocardiography and echocardiography,and yearly thereafter.Results Twenty-five patients were successfully treated with percutaneous induced thrombosis closure solely under echocardiography guidance.The mean operation time was (35.2 ± 6.1) minutes.The immediate residual shunt rates and 24 hours after operation were 28.0% (7/25 cases) and 16.0% (4/25 cases),respectively.All patients recovered and were discharged from hospital.The average hospitalization stay was (3.0 ± 0.6) days.The mean follow-up was (16.8 ± 12.3) months,residual shunt was observed in 2 patients (8.0%),and it decreased from 1.5 mm and 2.0 mm preoperatively to 0.8 mm and 1.0 mm postoperatively,respectively.All patients survived without peripheral vascular injury,cardiac perforation,PDA rupture or thrombembolia.Conclusions Percutaneous induced thrombosis closure of small PDA solely under echocardiography guidance is safe and effective.It can avoid occluder implantation and radiation injury.However,the residual shunt after operation needs following up closely.

ABSTRACT

Objective@#To compare the clinical outcome of patients with pulmonary valve stenosis underwent transthoracic and percutaneous balloon pulmonary valvuloplasty.@*Methods@#Clinical data of 806 patients diagnosed as pulmonary valve stenosis underwent transthoracic(171 patients as group A)or percutaneous balloon pulmonary valvuloplasty (635 patients as Group B) in Fuwai Hospital from February 2006 to January 2016 were analyzed retrospectively. There were 72 males in group A (42.1%) and 344 males in group B (54.2%). The average age was (1.6±1.1) years in group A and (21.0±18.5) years in group B. The median weight was 7.65 (7.68) kg (M(QR)) in group A and 43.75 (47.38) kg in group B. There were 732 (90.9%) patients followed up from 3 months to 10 years, with an average interval of (6.3±3.6) years. Sixty cases were ligated patent ductus arteriosus simultaneously, and 20 cases got Blalock-Taussig shunt at the same time of valvuloplasty in group A. There were 47 cases of transcatheter closure of atrial septal defect and 6 cases of transcatheter closure of patent ductus arteriosus in group B. The t test, rank sum test and χ2 test were used to compare data of two groups.@*Results@#There were no hospital death or cardiac tamponade and other serious complications for all patients. The postoperative hospital stayin group A was significantly longer than that in group B (8(5) days vs. 2(2) days, Z=-9.404, P=0.000). In every further consultation, patients were reviewed with transthoracic echocardiography to assess transpulmonary gradient and pulmonary regurgitation. There were significant difference between group A and B of preoperative transpulmonary pressure gradient ((80.6±22.4) mmHg vs.(72.6±20.5) mmHg, t=1.611, P=0.032, 1 mmHg=0.133 kPa) and so as transpulmonary pressure gradient reduction value ((55.9±21.0) mmHg vs. (46.6±23.4) mmHg, t=-1.710, P=0.026). Patients in both groups had good cardiac function during follow-up interval. One patient needed surgical valvuloplasty 10 months after percutaneous balloon pulmonary valvuloplasty and 1 case occurred moderate to severe tricuspid regurgitation in group B. During follow-up period, there was no significant difference between group A and B of transpulmonary pressure gradient ((22.3±6.5) mmHg vs. (25.2±12.6) mmHg, t=1.320, P=0.072), the incidence of pulmonary valve regurgitation in patients of group A was significantly lower than patients of group B (56.1% vs.65.2%, χ2=4.755, P=0.029).@*Conclusions@#The clinical outcome and complications are similar between patients underwent two different routes of balloon pulmonary valvuloplasty. Transthoracic balloon pulmonary valvuloplasty is more suitable for infant and underweight children patients with pulmonary valve stenosis. Percutaneous balloon pulmonary valvuloplasty is more suitable for the treatment of the elder children or adults.
