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...

Coronary Artery Disease V: Interprofessional Care

Interprofessional care for coronary artery disease includes pharmacological therapy and revascularization procedures.Pharmacological therapy for Coronary Artery Disease (CAD) aims to manage symptoms, prevent complications, and improve patient outcomes through various classes of medications:Antiplatelet Agents:Aspirin and Clopidogrel: These medications inhibit platelet aggregation, preventing blood clots, which is crucial for avoiding heart attacks and strokes. Doctors often prescribe these...

Acute Coronary Syndrome IV: Interprofessional Care

IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...

Area of Science:

Cardiovascular Surgery
Minimally Invasive Cardiac Surgery

Background:

Off-pump coronary artery bypass (OPCAB) surgery literature is extensive but lacks standardized techniques.
Variability in OPCAB approaches impacts consistent clinical application and outcomes.

Purpose of the Study:

To present a standardized, reproducible off-pump coronary artery bypass grafting (OPCAB) technique developed at KU Leuven.
To demonstrate a method that avoids the need for cardiopulmonary bypass (CPB) conversion.

Main Methods:

The described technique involves patient conditioning, bilateral internal mammary artery harvesting via sternotomy, and precise pericardial stitching for anterior heart exposure.
A stepwise approach for lateral and inferior heart exposure utilizes a posterior pericardial sling and an apical suction device for stabilization and visualization.
Coronary anastomoses are performed using routine shunting for anterior vessels and a strict no-touch technique for free grafts to in-situ arterial grafts.

Main Results:

The described technique allows for straightforward and replicable OPCAB without conversion to CPB.
The method facilitates exposure of anterior, lateral, and inferior coronary vessels for revascularization.
Utilizes a no-touch technique for anastomosing free grafts to in-situ arterial grafts.

Conclusions:

The standardized KU Leuven OPCAB technique is effective and reproducible.
This approach offers a viable alternative to conventional CABG with cardiopulmonary bypass.
The technique ensures consistent surgical outcomes through meticulous exposure and graft management.
