Course Description & Objectives: 

This course deals with the structural, the fundamental mechanisms and the functional control of the cardiovascular and respiratory systems. A detailed analysis of the rhythmical control of the heart, cardiovascular hemodynamic, capillary and coronary circulations, control of arterial blood pressure, the regulation of heart rate, cardiac output, and the peripheral vasculature is discussed. With respect to respiratory physiology, selected topics including pulmonary mechanics, principles of gas exchange and diffusion, transport of oxygen and carbon dioxide in the blood, and the regulation of respiration are addressed.                                                                                                                                                                                                                                                                                                                              Objectives:

  • Describe and discuss cardiovascular physiology and the influence of cardiovascular disease on normal physiology.
  • Know various operative approaches to the chest and understand indications for various preoperative studies of the chest and Intestinal systems and become familiar with their interpretation (Chest x-rays, angiography, echocardiograms, EKGs).
  • Demonstrate understanding of pathogenesis, pathophysiology, treatment, and outcome of the disease processes most frequently encountered in cardiovascular and Intestinal Tract practice (coronary circulation, theories of plaque development, indications for angioplasty versus bypass, choice of valvular procedures and operations, for example).
  • Understand and demonstrate knowledge of basic theory and physiology of the heart-lung machine (cardiopulmonary bypass) and ventricular assist devices.
  • Demonstrate skill in effective information exchange with patients, their families, and other members of the Surgery Team.
Learning Outcomes: 
  • Demonstrate an awareness of physical examination findings in cardiac diseases.
  • Continue to develop and improve technical skills in the Operating Room.
  • Demonstrate the ability to appropriately utilize the ICU for proper postoperative care and management of patients with cardiovascular instability from one or more of the following:

a. Common arrhythmias.b. Tamponade (early and late).c. Low cardiac output.d. Excessive bleeding.e. Pulmonary problems.f. The impact of the surgery and underlying health problems.g. Low urine output.h. Central nervous system complications.

  • Understand the multidisciplinary role of the Surgeon, Nurses, and the Operating Room Team in the provision of safe and high quality surgery care.
  • Interact with patients and their families in a respectful, sensitive, and ethical manner.
  • Demonstrate ability to utilize scientific studies to provide high quality cardiac and Intestinal tract surgical care.
  • Facilitate and supports the education of medical students, junior residents, and other healthcare team members.

   Upon completion of the rotation, the Resident will be familiarized with the discipline of the systems’ surgery in theory and in practice.
