We have developed a swine model for the target delivery of pharmacological agents within the pericardial space/fluid. Using this approach, the relative benefits of administered agents on induced atrial fibrillation, relative refractory periods and/or ischemic protection can be investigated.

Surgical correction of ALCAPA is highly recommended, regardless of age or the degree of intercoronary collateralization. This protocol presents a technique for the direct re-implantation of adult-type ALCAPA into the aorta to re-establish the dual-coronary perfusion. Whenever feasible, direct re-implantation is preferred to other surgical correction techniques.

Blood pressure monitoring is one of the essential vital signs, and for a majority of patients, measuring it utilizing non-invasive techniques provides accurate values. However, there are situations in which the blood pressure requires more exact, specific, and reliable measurements.

Numerous genetic manipulations and/or intramyocardial injections of genes, proteins, cells, and/or biomaterials are superimposed upon the dimension of time in studies of acute ischemia/ reperfusion injury and chronic remodeling in mice. This video illustrates the microsurgical procedures for ischemia/reperfusion, permanent coronary artery ligation, and intramyocardial injection studies.

2024
With the rapid advancement of laparoscopic techniques, the minimally invasive benefits of laparoscopic splenectomy combined with pericardial devascularization have become increasingly evident. In this context, we present a protocol for performing laparoscopic splenectomy alongside pericardial devascularization to treat hypersplenism and esophageal variceal hemorrhage resulting from portal hypertension.
FAQs
Its arterial source is not fixed: it may arise from branches of the internal thoracic artery or from the musculophrenic artery. This variation can change the vessel’s route through the thorax and its relationship to adjacent pericardial tissues. Recognizing these differences helps explain why vascular anatomy may appear different across diagnostic images or dissection specimens.
Small vessels within the pericardial tissues distribute oxygenated blood across a thin, specialized region rather than supplying a large muscle mass. This arrangement supports local metabolic needs and contributes to tissue repair. Because the network is fine and closely associated with the pericardium, changes in its course or integrity can influence localized perfusion around the heart.
The vessel forms part of the arterial supply connected to thoracic branches near the heart. Its possible relationship with the internal thoracic and musculophrenic arteries provides an anatomical pathway for blood to reach the pericardial tissues. Mapping these connections is important because neighboring vessels and their branches may have different courses in the same operative field.
Damage may produce bleeding within the thoracic or pericardial region and can also reduce blood delivery to the tissues served by the injured branch. The significance depends on the vessel’s size, location, and connections. For that reason, identifying its expected course and possible variation is relevant when examining or working near the heart and surrounding thoracic structures.
Imaging assessment benefits from knowledge of the artery’s possible origins and course. A branch from the internal thoracic or musculophrenic artery may follow a route that differs from the expected pattern, so anatomical variation must be considered when interpreting vessels near the pericardium. This context helps distinguish normal vascular differences from findings that may require further evaluation.
Procedures involving the heart, pericardium, or adjacent thorax should account for the vessel because an unrecognized branch may be cut, compressed, or otherwise disturbed. Such injury can cause bleeding or alter local tissue perfusion. Anatomical planning that includes its potential origins and fine pericardial distribution therefore supports safer handling of nearby tissues.
