Cannulation for Minimally Invasive Cardiac Surgery

Aortic cannulation system for minimally invasive mitral valve surgery.

somewhat stiffer than virgin young material (such as with a bioprosthesis or in older patients). Assessment of the results of repair by direct visualization is the commonly used technique not imitating diastolic pressure. Without diastolic pressure, the leaflets show unpredictable irregularities in their morphologic appearance, making the assessment difficult (Figure 1, B and C). The strength o...

Minimally invasive cardiac surgery defined.

There is no operation as complex, yet as fundamentally unchanged over time, as conventional coronary artery bypass grafting (CABG). This remarkable achievement is attributed to the operation's adaptability to a wide variety of clinical settings; its reproducibility, although performed by surgeons all across the world; and its proved track record for safety and effectiveness. A monumental effort...

Distal leg protection for peripheral cannulation in minimally invasive and totally endoscopic cardiac surgery.

BACKGROUND The introduction of minimally invasive and totally endoscopic cardiac surgery is associated with increased use of femoral artery perfusion. Selective antegrade perfusion of the cannulated artery may be a helpful strategy to avoid ischemia of the lower extremities. The aim of the study was to evaluate the efficacy of selective distal vessel perfusion under continuous monitoring of oxy...

Future of minimally invasive cardiac surgery.

Dynamic organ modeling for minimally-invasive cardiac surgery

While most currently available minimally invasive robotically assisted cardiac surgical systems do not employ 3D image guidance, such support can be generated using pre operative images such as CT. Previously we demonstrated a virtual model of the thorax with simulated surgical instruments, and a pulsating virtual model of the coronary arteries. In this paper we report the overlay of optical en...
