Congenital Cardiology
Ventricular Septal Defect
Use echocardiography to define ventricular septal defect anatomy and hemodynamic effect, then distinguish patients suitable for observation from those needing congenital heart disease team assessment for surgical or transcatheter closure.
First decision
Define anatomy, shunt burden, and ventricular consequences
The initial objective is to establish whether the VSD is anatomically simple and hemodynamically tolerated or requires closure planning.
Obtain transthoracic echocardiography with two-dimensional imaging and color/spectral Doppler to localize the defect, characterize its relation to adjacent valves, assess chamber consequences, and estimate shunt hemodynamics. Echocardiography is the principal modality for VSD evaluation; Doppler-derived hemodynamic assessment can include shunt flow calculations.Wolters Kluwer+1Wolters KluwerEchocardiographic evaluation of ventricular septal defectsWileyPractical Cardiovascular Medicine - Wiley Online Library
When noninvasive imaging does not adequately resolve shunt magnitude or pulmonary vascular status before a closure decision, perform cardiac catheterization to measure pulmonary and systemic flow ratio (Qp/Qs) and pulmonary-to-systemic resistance ratio (Rp/Rs). These measures have been used to derive a hemodynamic index in children with isolated VSD.WileyWileyDetermination of the anatomical size of ventricular septal defects on ... A reported catheterization example of a clinically important VSD demonstrated Qp:Qs 3.0:1 with pulmonary vascular resistance 2.3 Wood units, illustrating how invasive measurements integrate shunt volume and pulmonary vascular load rather than defect diameter alone.journal chestnetjournal chestnetVentricular Septal Defect Noted by Two ... - CHEST Journal
Interpret physiology in relation to pulmonary vascular resistance. In large VSDs, significant left-to-right shunting develops when PVR relative to systemic vascular resistance falls below 0.5:1; this explains why hemodynamic burden may evolve as pulmonary vascular physiology changes.publications aappublications aapPART 2: ANSWERS CARDIOLOGY - AAP Publications
Use echocardiography to determine whether the defect is perimembranous, muscular, or conal/supracristal, because anatomic relation to valves and conduction tissue changes closure feasibility and risk.Wolters Kluwer+2Wolters KluwerEchocardiographic evaluation of ventricular septal defectsWileyVentricular Septal Defect - Wiley Online LibraryjtcvsSurgical management of the conal (supracristal) ventricular septal ...

Anatomic branch
Match VSD anatomy to surveillance and closure planning
The closure approach depends on VSD location, multiplicity, and proximity to the aortic and tricuspid valves or conduction tissue.
Perimembranous VSD is the lesion category specifically addressed in transcatheter closure guidance. Patient selection should occur through a multidisciplinary team that includes an interventional cardiologist and cardiac surgeon with congenital heart disease expertise, with particular caution in children and asymptomatic patients.nice org uknice org uk[PDF] HTG325 Percutaneous closure of patent foramen ovale to prevent ...
Muscular VSDs may be multiple. In complex “Swiss cheese” ventricular septation, more than one occlusion device has been used to obtain near-complete closure; this anatomy should prompt planning at a center experienced with complex congenital structural interventions rather than a single-device assumption.BMJBMJClosing down: transcatheter closure of intracardiac defects ... - Heart
Conal (supracristal) VSD assessment should include careful echocardiographic review and, where required, catheterization and operative evaluation. In a surgical series, aortic valve abnormalities were present preoperatively in 72% of patients, making valve-focused imaging consequential when this anatomic subtype is suspected.jtcvsjtcvsSurgical management of the conal (supracristal) ventricular septal ...
For any anatomy considered for transcatheter closure, confirm that the operator is trained in the technique and complication management and that emergency cardiac surgical access is available.nice org uknice org uk[PDF] HTG325 Percutaneous closure of patent foramen ovale to prevent ...
If a VSD lies adjacent to valve tissue or there is pre-existing valve dysfunction, define the valve lesion before choosing a device-based approach because new aortic or tricuspid regurgitation has been reported after perimembranous device closure.nice org uknice org uk[PDF] HTG213 Transcatheter endovascular closure of perimembranous ...
Intervention
Choose closure strategy through congenital heart disease expertise
Closure is a structural decision requiring anatomic suitability, hemodynamic assessment, and a plan for procedural rescue and rhythm follow-up.
For perimembranous VSD, transcatheter endovascular closure may be undertaken when selected patients have been evaluated within a multidisciplinary congenital heart disease program. Guidance specifies that children should undergo the procedure only in specialist pediatric cardiology units; across ages, the procedure should be performed by cardiologists trained in both implantation and complication management, with access to emergency cardiac surgery.nice org uknice org uk[PDF] HTG325 Percutaneous closure of patent foramen ovale to prevent ...
Do not treat transcatheter closure as interchangeable with surgery for every VSD anatomy. Surgical management remains relevant when anatomy is complex, when multiple defects require a tailored strategy, or when adjacent aortic valve pathology requires direct operative assessment or repair.BMJ+1BMJClosing down: transcatheter closure of intracardiac defects ... - HeartjtcvsSurgical management of the conal (supracristal) ventricular septal ...
Counsel explicitly about conduction and device-related complications before perimembranous device closure. Reported series using Amplatzer devices described complete heart block from 0% to 1.9%, left bundle branch block from 0% to 4%, aortic regurgitation from 0% to 4%, tricuspid regurgitation from 0% to 8%, tricuspid stenosis from 0% to 0.9%, and device embolization from 0% to 7.7%.nice org uknice org uk[PDF] HTG213 Transcatheter endovascular closure of perimembranous ...
Document a baseline ECG before device closure and obtain post-procedure ECG follow-up, because complete heart block occurred immediately in 1.07% and conduction abnormalities persisted or appeared at least 3 months after closure in a focused ECG case series.nice org uknice org uk[PDF] HTG213 Transcatheter endovascular closure of perimembranous ...
Involve cardiac surgery before device closure rather than only after a complication occurs; emergency surgical access is a stated procedural requirement.nice org uknice org uk[PDF] HTG325 Percutaneous closure of patent foramen ovale to prevent ...
Monitoring
Follow repaired and unrepaired VSDs for rhythm, valve, and infection-related complications
Follow-up intensity should reflect anatomy, residual hemodynamics, repair status, and new clinical events.
After transcatheter closure, reassess device position, residual shunt, and aortic and tricuspid valve function by echocardiography, and obtain ECG surveillance for new atrioventricular or intraventricular conduction abnormalities. In reported series, new complete right bundle branch block, incomplete right bundle branch block, and left anterior hemiblock were documented at least 3 months after perimembranous closure.nice org uknice org uk[PDF] HTG213 Transcatheter endovascular closure of perimembranous ...

Common questions
When is contrast echocardiography useful for suspected VSD?
Peripheral contrast echocardiography has been described as a highly specific real-time echocardiographic method for demonstrating VSD flow, but routine anatomic and hemodynamic characterization remains centered on standard two-dimensional and Doppler echocardiography.journal chestnet+1journal chestnetVentricular Septal Defect Noted by Two-Dimensional ...Wolters KluwerEchocardiographic evaluation of ventricular septal defects
