An Unusual Cause of Hypoxemia after Orthopedic Surgery on an Elderly Patient

Pedro Carvalho et al. Daniela Meireles José Luís Martins Marco Costa Ana Briosa Neves

Introduction

Various conditions can cause post-operative hypoxemia, especially in elderly patients. However, a new symptomatic cardiac shunt is a very rare and unexpected complication in this setting. This study presents a case of refractory hypoxemia after orthopedic surgery due to right-to-left (R-L) shunt via a patent foramen ovale (PFO).

Abstract

Background:

Atrial fibrillation (AF) is a cardiac arrhythmia with high risk for thromboembolic events, specially stroke.

Objective:

To assess the safety of left atrial appendage closure (LAAC) with the Amplatzer Cardiac Plug for the prevention of thromboembolic events in patients with nonvalvular AF.

Methods:

This study included 15 patients with nonvalvular AF referred for LAAC, 6 older than 75 years (mean age, 69.4 ± 9.3 years; 60% of the male sex).

Results:

The mean CHADS₂ score was 3.4 ± 0.1, and mean CHA₂DS₂VASc , 4.8 ± 1.8, evidencing a high risk for thromboembolic events. All patients had a HAS-BLED score > 3 (mean, 4.5 ± 1.2) with a high risk for major bleeding within 1 year. The device was successfully implanted in all patients, with correct positioning in the first attempt in most of them (n = 11; 73.3%).

Conclusion:

There was no periprocedural complication, such as device migration, pericardial tamponade, vascular complications and major bleeding. All patients had an uneventful in-hospital course, being discharged in 2 days. The echocardiographic assessments at 6 and 12 months showed neither device migration, nor thrombus formation, nor peridevice leak. On clinical assessment at 12 months, no patient had thromboembolic events or bleeding related to the device or risk factors. In this small series, LAAC with Amplatzer Cardiac Plug proved to be safe, with high procedural success rate and favorable outcome at the 12-month follow-up.
