Aneurysm III: Interprofessional Care

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Coronary Artery Disease V: Interprofessional Care

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...

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Aortic Regurgitation III: Medical Management

Aortic Regurgitation III: Medical Management

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

Aneurysm IV: Nursing Management

Aneurysm IV: Nursing Management

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

Acute Coronary Syndrome IV: Interprofessional Care

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
Medical Education
Clinical Research

Background:

The Western Aortic Collaborative (WAC) is a new academic model for thoracic aortic surgery.
It aims to advance surgical techniques, surgeon education, and multi-institutional clinical research.
The WAC employs a hybrid model combining in-person meetings and videoconferencing.

Purpose of the Study:

To establish a collaborative network for aortic surgeons in the Western region.
To promote the cross-pollination of ideas and experiences among surgeons.
To address knowledge gaps in aortic surgery through multi-institutional research.

Main Methods:

Utilizing a horizontal organizational structure to encourage idea sharing.
Identifying key research areas in aortic surgery with significant knowledge gaps.
Developing a novel, cloud-based database linked to the Society for Thoracic Surgeon database.
Leveraging institutional practice differences for a natural experiment design.

Main Results:

Successfully created a regional community of aortic surgeons in its inaugural year.
Established five high-priority research topics from the aortic root to the left subclavian artery.
Implemented a novel, cloud-based database for multi-institutional research.

Conclusions:

The WAC effectively utilizes technology and collaborative meetings to achieve its research and educational goals.
The hybrid model fosters a regional community dedicated to advancing aortic surgery.
The established database infrastructure supports subspecialized research and data linkage.
