The regenerative capacity of the mammalian heart is insufficient to recover from myocardial infarction. Stem cells are currently considered as a promising and valuable tool to replace the, often large, loss of contractile tissue. One of the bottlenecks hampering fast clinical application is the large amount of cells required to replace a single damaged region combined with an appropriate strategy to succeed in homogeneous repair.

Objective: To demonstrate the application of tattooing for the intraoperative localization of posterior wall gastric leiomyoma during laparoscopic resection. The preoperative injection of Indian ink in the tumor-bearing area of the posterior gastric wall eliminates the need to perform anterior wall gastrostomy or intraoperative upper endoscopic tumor localization.

Methods: A patient with posterior wall gastric leiomyoma was marked with Indian ink during preoperative upper endoscopy.

Thoracic ectopia cordis is a rare congenital defect most often seen in association with sternal and congenital heart defects. Surgical correction of these defects is complex and generally requires a staged closure including (1) coverage of the "naked heart," (2) placement of the heart into the thoracic cavity, and (3) sternal or thoracic reconstruction. Survival past the perioperative period is rare, with only 2 reported cases in the English-language literature.

The relationship between mortality, surgical volume, and location was investigated in the university medical centers (UMCs) in the Greater New York metropolitan area for patients undergoing coronary artery bypass grafting (CABG) in 1986. Three high-volume and five low-volume institutions, with a total of 49 surgeons, performed a total of 3,408 CABG operations. The crude mortality rates were 4% for simple, 14.

Renal cell carcinoma is known to invade the inferior vena cava and may extend its entire length. Profound hypothermic circulatory arrest has been demonstrated to be a very effective technique to facilitate removal of tumor thrombus from the cava while limiting the amount of blood loss. We describe an innovative method of ensuring complete removal of tumor thrombus from the retrohepatic cava with a fiberoptic bronchoscope introduced through the right atrium during profound hypothermic circulatory arrest.
