Recognize
The signs on the monitor, the image and the patient.
- MonitorSudden hypotension during or right after balloon expandable deployment or post dilation (rupture), or with ST change and ventricular arrhythmia (obstruction) 12.
- EchoA new pericardial effusion or a root hematoma (rupture); new left ventricular wall motion loss with no effusion (obstruction) 2.
- ImageContrast in the root wall or the pericardium (rupture); a left main that no longer fills on root injection (obstruction) 2.
- PatientPain, agitation or loss of consciousness in a sedated patient.
- PatientRisk factors: area oversizing and heavy left ventricular outflow calcium for rupture; low coronary height, a narrow sinus and valve in valve for obstruction 12.
Act now
In the order the operator does them. The first three come first, whatever else is happening.
- Say what you see and call the heart team surgeon and anesthesia to the room now.
- Echo now (TEE or TTE) and a root injection: effusion points to rupture, wall motion loss to obstruction 2.
- Support the circulation: vasopressors, and CPR or venoarterial ECMO if it fails 3.
- Rupture with tamponade: pericardiocentesis with autotransfusion, reverse heparin, and surgery for an uncontained rupture 45.
- Rupture contained without tamponade: no further dilation; some contained root hematomas have been observed without surgery.
- Obstruction: wire the coronary through a guide and stent from the ostium out past the valve frame (chimney); surgery or ECMO if it fails 2.
- Self expanding valve not yet released: recapture or reposition may relieve an obstruction.
- Record the time of each event for the VARC-3 report 6.

Drugs
Adult doses as the cited source gives them. Check your formulary and the label.
- ProtamineReverse heparin for a rupture with bleeding.Weight based dose in the Cath Med App
- Norepinephrine0.1 to 0.5 mcg/kg/min IV 7.
- EpinephrineArrest: 1 mg IV every 3 to 5 minutes 8; shock: 2 to 10 mcg/min IV 7.
- HeparinKeep the ACT in range while stenting an obstructed coronary.Weight based dose in the Cath Med App
Who to call
The escalation ladder, first call first.
- Heart team surgeon: at once for either event.
- Anesthesia: airway and hemodynamics.
- Echo: TEE or TTE in the room.
- Perfusion and ECMO team: for collapse that does not respond.
- Second interventionalist: to wire and stent the coronary.
The bailout step by step
Chimney stent for coronary obstruction after TAVR 29
- Support the circulation while you work; ECMO early if it fails.
- Engage the obstructed coronary with a guide through or around the valve frame.
- Wire the vessel; use a guide extension if the guide will not seat.
- Choose a stent long enough to reach from the coronary to above the displaced leaflet.
- Deploy it from inside the coronary out past the valve frame, flared toward the aorta.
- Check flow and wall motion; image the ostium if you can.
- Failure: surgery.
Prevent
- CT planning: annulus area and perimeter, root and outflow calcium, coronary heights and sinus dimensions 12.
- Avoid aggressive oversizing of balloon expandable valves in heavily calcified roots 1.
- High obstruction risk: protect the coronary with a wire and an undeployed stent, plan intentional leaflet laceration (BASILICA), or choose surgery 9.
- Have the surgeon and ECMO available for high risk anatomy.
After care and documentation
- Echo for effusion and wall motion; ECG and troponin.
- Report by VARC-3 definitions; enter the event in the TVT registry 6.
- Debrief the heart team; disclose to the patient and family.
Practice
No emergency simulator case for these yet; the structural simulator in the app runs TAVR cases in which complications show only through their signs. Browse the case library.
