Cardiomyopathy VII: Pre and Post Operative Nursing Management

Cardiomyopathy VII: Pre and Post Operative Nursing Management

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Summary

A new heart positioning device (Tentacles) facilitated excellent surgical access for multivessel off-pump coronary artery bypass (OPCAB) grafting. While haemodynamic stability was maintained, additional catecholamine support was required during heart displacement.

Background:

Multivessel off-pump coronary artery bypass (OPCAB) grafting requires heart displacement for target vessel exposure.
Maintaining haemodynamic stability during OPCAB is a significant surgical challenge.
A novel heart positioner, Tentacles, was evaluated for its efficacy and haemodynamic impact.

Purpose of the Study:

To assess the effectiveness of the Tentacles device in providing surgical access during multivessel OPCAB.
To investigate the haemodynamic effects of using the Tentacles device for heart displacement.
To monitor for myocardial ischaemia during the procedure.

Main Methods:

A prospective clinical study involving 50 patients undergoing multivessel OPCAB.
Utilized the Tentacles device for heart positioning.
Monitored haemodynamic parameters: mean arterial blood pressure (MAP), cardiac index (CI), and stroke volume index (SVI).
Assessed myocardial ischaemia using transoesophageal echocardiography (TEE) and ECG ST-segment analysis.

Main Results:

The Tentacles device enabled rapid and secure exposure of all cardiac walls.
Minor decreases in MAP and increases in CI were observed during anterior wall exposure.
Stroke volume index (SVI) decreased significantly when exposing the lateral and posterior walls.
Increased norepinephrine administration was noted during heart displacement, while sinus rhythm and ischaemia markers remained stable.
Postoperative troponin I levels were within expected ranges.

Conclusions:

The Tentacles device offers excellent surgical access for multivessel OPCAB procedures.
Haemodynamic stability was generally maintained, though catecholamine support was necessary during heart displacement.
The device is a viable option for improving surgical exposure in OPCAB surgery.
