General endotracheal with TEE and arterial line
The patient is a [age]-year-old [male/female] with severe [aortic stenosis (AVA [X] cm², mean gradient [X] mmHg, peak gradient [X] mmHg) / aortic regurgitation (LVEDD [X] mm, LVEF [X]%)], presenting with [exertional dyspnea / syncope / angina / asymptomatic, meeting guideline criteria]. Surgical AVR was recommended by Heart Team. The risks, benefits, and alternatives including TAVR were discussed and informed consent was obtained.
The aortic valve was [tricuspid / bicuspid / rheumatic] with [heavily calcified / fused] leaflets. The aortic annulus measured [X] mm on TEE. The leaflets were [excised and the annulus debrided of calcium]. The native valve measured [X] mm. The prosthetic valve was seated without obstruction. TEE post-bypass confirmed [no paravalvular leak / trace paravalvular leak (hemodynamically insignificant)], EF [X]%, and mean gradient [X] mmHg.
The patient was positioned supine. A median sternotomy was performed. The pericardium was opened and the ascending aorta, right atrium, and aortic root were exposed. Cardiopulmonary bypass was instituted via aortic and venous cannulation. [Cold blood / del Nido] cardioplegia was given antegrade.
A transverse aortotomy was made [2 cm above the right coronary ostium]. The aortic valve was inspected. It was [tricuspid / bicuspid, with heavy calcification]. The valve leaflets were excised and the annulus was debrided of calcium to a smooth, non-obstructing rim. [Care was taken to avoid injury to the anterior leaflet of the mitral valve and the membranous septum.]
The annulus measured [X mm]. A [21 / 23 / 25]-mm [bioprosthetic (Carpentier-Edwards Perimount / INSPIRIS) / mechanical (On-X)] valve was selected. The valve was seated with [X] pledgeted interrupted [2-0 Ethibond] sutures in [everting mattress / non-everting] configuration. The valve was lowered into position and the sutures were tied. The valve moved [freely] with no obstruction.
The aortotomy was closed with [3-0 Prolene] running suture in two layers. Air was de-aired from the aortic root. Clamps were released. The heart [resumed sinus rhythm spontaneously / was defibrillated]. The patient was weaned from CPB. Post-bypass TEE confirmed [no paravalvular leak, EF X%, mean gradient X mmHg].
Protamine was administered. Hemostasis was achieved. Mediastinal chest tubes were placed. The sternum was closed with sternal wires. The wound was closed in layers.

The patient was transferred to the cardiac ICU intubated. [Anticoagulation with heparin was initiated and transitioned to warfarin (target INR [2.0-2.5 / 2.5-3.5]) for mechanical valve.] [Aspirin only for bioprosthetic valve.]

Minimally Invasive AVR (Mini-Sternotomy / Right Anterior Thoracotomy)
AVR was performed via [upper hemisternotomy (J-incision) / right anterior minithoracotomy] for minimally invasive access. The sternum was divided to the [3rd / 4th] intercostal space. A [modified] cannulation strategy was used: [standard aortic / femoral artery + femoral vein]. The aortotomy and valve replacement proceeded as described. Advantages include reduced blood loss, shorter length of stay, and superior cosmesis; disadvantages include limited surgical access and longer CPB time for complex anatomy.
Charting Tips
- Document paravalvular leak assessment by post-bypass TEE. Trace paravalvular regurgitation at a bioprosthetic valve is generally acceptable. For mechanical valves, any more-than-trace paravalvular jet warrants consideration of return to bypass; trace jets may be observed briefly post-protamine and re-evaluated before closure. Document the TEE finding, severity (trace/mild/moderate), and the management decision.
- Document final valve position and gradient on post-bypass TEE. A mean gradient >15 mmHg for a new bioprosthetic AVR is elevated and warrants evaluation; >20 mmHg suggests obstruction or patient-prosthesis mismatch and should prompt consideration of return to bypass for revision or upsizing. Patient-prosthesis mismatch is defined as projected indexed EOA 0.85 cm2/m2 or less (moderate) or 0.65 cm2/m2 or less (severe). Document the measured mean gradient and indexed EOA.
- Document anticoagulation plan for mechanical valve. Mechanical valves require lifelong anticoagulation. Per ACC/AHA 2020 guidelines: target INR 2.5 (range 2.0-3.0) for On-X mechanical AVR without additional risk factors; target INR 3.0 (range 2.5-3.5) for older-generation mechanical valves or additional thromboembolic risk factors. Document when heparin was initiated and the warfarin transition plan.
- Document cross-clamp time and total CPB time. These are required STS quality metrics. Cross-clamp time and CPB time >120 minutes are associated with increased operative morbidity. Both should appear in the operative note.
- Document placement of temporary epicardial pacing wires. Atrial and ventricular epicardial wires are standard after AVR and must be documented in the operative note. Complete heart block can develop post-AVR due to proximity of the AV node and bundle of His to the noncoronary cusp annulus.
Billing Tips
- Bill 33405 for open surgical aortic valve replacement (SAVR, 40.29 wRVU, 90-day global). Use for traditional sternotomy AVR with cardiopulmonary bypass.
- TAVR uses entirely separate codes: 33361 for percutaneous/transfemoral (22.21 wRVU, 0-day global) or 33362 for open transcatheter approach (23.93 wRVU). Note TAVR codes have a 0-day global period vs. 90-day for SAVR.
- Concomitant procedures at the time of SAVR are separately billable using procedure-specific combinations. Modifier -51 is generally not applied to cardiac surgery combinations; procedure-specific pairing rules apply. AVR + CABG: bill 33405 plus the arterial graft code (33533-33536) and venous add-ons (33517-33519) as appropriate. Concomitant surgical maze: bill add-on code 33259 (not a standalone maze code). Document each component in its own operative section.
- Cardiopulmonary bypass is bundled into the primary valve replacement code (33405/33406/33410) and is not separately billable as a surgeon CPT code. There is no surgeon-billable CPT code for CPB. Note: 33508 is the add-on code for endoscopic vein harvest during CABG and is entirely unrelated to CPB or valve surgery.
- 90-day global period for SAVR: anticoagulation management, valve clinic follow-up, and routine echo surveillance are bundled for the surgical fee. Cardiology follows independently and bills their own E/Ms.
