Update of Transcatheter Closure of Ventricular Septal Defect in China Yong-wen Qin Department of Cardiology, Changhai Hospital, Second Military Medical University, Shanghai
1、The number and quality of VSD intervention improved during past ten years
The first cases of VSD intervention in our center The first pmVSD patients treated with symmetric occluder (2001.12,21) The first post-MI VSD patient treated with symmetric occluder (2001.10)
Patient number * year Development of CHD intervention from 1990s-2011 in China
2、Three kind of VSD devices invented and clinical use in China
Modified VSD device in China symmetric occluder thin waist occluder asymmetric occluder
The classification of VSD by ventriculography Individualization choice of the occluder according to anatomy of VSD • A tubular • B window-like • C aneurysmal • D infundibular
Infundibular VSD symmetric occluder
How to choose the occluder according to VSD Intracristal VSD asymmetric occluder
Intracristal VSD Symmetric device ---Aortic valve regurgitation asymmetric device ---no aortic valve regurgitation
Intracristal VSD Aortic valve regurgitation--- device inclined to one side The direction of left disk marker should be apex
Intracristal VSD When the marker turn to apex, aortic valve regurgitation became trace
Intracristal VSD No aortic valve regurgitation-- long rim direction pointed to cardiac apex
VSD PV Echo: subpulmonary VSD---near PV
Postoperation, no aortic regurgitation However, occluder maybe oversized
Multi-hole VSD---device choice multi-hole VSD thin waist occluder
VSD with two holes VSD1 VSD1 VSD2 device For VSD2
Large VSD -2 14mm A6B2 device
Large VSD -3 No aoric valve regurgitation ,no TVR
PDA device for large VSD 20mm PDA device
Postoperative residual perimembranous VSD Transcatheter closure of postoperative residual perimembranous VSD
PS and large VSD VSD 17mm, device 24mm
3、Conduction Block complicated with VSD Intervention: experience in china
Clinial trial data of Amplatzer VSD device Catheter Cardiovasc Interv. 2006, 68(4):620-8. (n=100) J Am Coll Cardiol. 2006, 47(2): 319-25. (n=35) Eur Heart J. 2007, 28: 2361. (n=430)
The data on VSD occluder in China from 21 centers (N=9311, 2007) • Success rate 96.45% • Death 0.05% (5) • Transient cAVB 0.63% (59) • PPM 0.09% (8)
2011 registry data in China • 5474 cases with vsd in 394 hospital in china • PPM 1case
The data from Changhai hospital (2001-2012) • 2001-2002, 196 cases underwent percutaneous procedure (using symmetry device), no cAVB • 2003-2006, among 300 cases (Symmetry , Eccentric、thin waist devices), 11 cases complicated transient 3rd degree AVB, permanent pacemaker occur in 1 case • 2007-2012, sequence 550 cases with Symmetry , Eccentric,thin waist devices, cAVB occur 1 patient
The possible reason of increase AVB from 2003 to 2006 ? • Patients: patients non-selected, consecutive patients admitted • Doctors: personnel stability, and operation technology maturity • Indication: increased intracristal multi-holes and aneurysm type VSD • Devices: Application of asymmetric occluder
Device waist length and AVB • 2001--2003---more than 3.5 mm---no case with AVB • 2003--2006---less than 2.5mm---12/300 with AVB • 2007--2012---more than 3.5mm---no case with AVB
