A nurse is caring for a client with severe aortic stenosis who is scheduled for balloon valvuloplasty. Which nursing intervention is most important to implement in the immediate postprocedure period?

## 보기

1. Encourage early ambulation to prevent thromboembolism
2. Administer prescribed anticoagulants as ordered
3. Monitor the catheter insertion site for bleeding and hematoma formation **✔ 정답**
4. Assess heart sounds for improvement in murmur intensity

**정답: 3**

## 해설

Monitoring the catheter insertion site is the priority to prevent life-threatening hemorrhage post-valvuloplasty. Other interventions like anticoagulants or heart sound assessment are important but not immediate priorities.

Understanding the Procedure and Its Risks

Balloon aortic valvuloplasty (BAV) for severe aortic stenosis is a percutaneous cardiac catheterization procedure. During BAV, a catheter with a balloon at its tip is advanced through a major artery—most commonly the femoral artery—to the stenotic aortic valve, where the balloon is inflated to fracture calcified deposits and separate fused commissures, thereby increasing the valve orifice area [1]. Because the procedure requires arterial access with a relatively large-bore sheath, the integrity of the arterial puncture site is the primary concern in the immediate postprocedure period.

Why Monitoring the Catheter Insertion Site Is the Priority

After any cardiac catheterization, the most common vascular complications are bleeding and hematoma formation at the access site [2]. A systematic review on post-cardiac catheterization care confirms that hematoma and pain remain frequently reported complications, which can prolong hospitalization and increase costs [2]. In the context of BAV, the risk is heightened because larger sheaths are used, and patients often receive anticoagulation during the procedure. A developing hematoma can lead to retroperitoneal bleeding, pseudoaneurysm, or arteriovenous fistula if not identified and managed promptly. Therefore, frequent assessment of the insertion site for oozing, swelling, ecchymosis, and a palpable hematoma, along with monitoring distal pulses and limb perfusion, is the most critical nursing action to prevent life-threatening hemorrhage and preserve limb viability.

Analysis of the Other Options

**Option 1: Encourage early ambulation to prevent thromboembolism.** This is contraindicated in the immediate postprocedure period. After arterial sheath removal, the patient must remain on bed rest with the affected leg kept straight for a prescribed period—typically 4 to 6 hours—to allow adequate hemostasis at the puncture site. Early ambulation would disrupt clot formation at the arteriotomy and precipitate bleeding or hematoma expansion.

**Option 2: Administer prescribed anticoagulants as ordered.** While anticoagulation may be part of the postprocedure regimen to prevent thrombus formation on the disrupted valve surface or at the access site, its administration is not the most immediate nursing priority. The nurse must first ensure that the access site is stable and that there is no active bleeding before administering any agent that could exacerbate hemorrhage. The assessment for bleeding takes precedence over medication administration in the immediate period.

**Option 4: Assess heart sounds for improvement in murmur intensity.** Although echocardiographic and auscultatory improvements are expected outcomes of a successful valvuloplasty, this assessment does not address the most time-sensitive safety risk. The murmur of aortic stenosis may decrease in intensity, but restenosis or insufficient gradient reduction is a subacute to chronic concern. In the first hours after the procedure, vascular access complications pose a far greater threat to the patient’s safety than the degree of murmur improvement.

The immediate postprocedure nursing priority following balloon aortic valvuloplasty is vigilant monitoring of the arterial access site for bleeding and hematoma formation, as this directly addresses the most common and potentially serious complications of the intervention [2].References (research sources)

## 임상 시나리오

Post-Balloon Valvuloplasty Site CareImmediate Priority: Monitor for Vascular Complications
The most critical intervention is frequent assessment of the catheter insertion site for bleeding and hematoma formation. This is due to the use of a large-bore arterial sheath in the femoral artery.

Assess the site every 15 minutes for the first hour, then every 30 minutes to 1 hour. Note any oozing, swelling, ecchymosis, or palpable mass. Concurrently, monitor distal pulses and limb perfusion to detect arterial insufficiency.

Critical AlertSuspect retroperitoneal bleeding if the patient develops sudden hypotension, flank or back pain, and a dropping hematocrit. This is a life-threatening emergency requiring immediate intervention.

## 핵심 개념

- **Balloon Aortic Valvuloplasty (BAV)** — A percutaneous cardiac catheterization procedure where a balloon is inflated across a stenotic aortic valve to fracture calcified deposits and increase the valve orifice area.
- **Hematoma** — A localized collection of blood outside blood vessels, commonly occurring at a catheter insertion site due to arterial wall trauma, presenting as swelling, pain, and ecchymosis.
- **Retroperitoneal Bleeding** — A life-threatening complication of femoral artery access where bleeding occurs into the retroperitoneal space, often presenting with back pain, hypotension, and a decreasing hematocrit.
