Dr. Muehrcke studies several key areas related to surgery and heart health. His research primarily involves fluorescence-guided surgery using a dye called Indocyanine Green, which helps surgeons visualize blood vessels and tumors more effectively during operations. This technique can lead to better surgical results and increased patient safety. He also examines treatments for patients with severe angina who are not candidates for traditional surgeries, exploring options like transmyocardial laser revascularization. Additionally, he has researched outcomes related to surgery for infections in artificial heart valves and how blood flow impacts heart function during times of oxygen shortage.
Key findings
In a study on fluorescence-guided surgery, 41 out of 44 best practice statements were agreed upon by experts, confirming its effectiveness and safety for surgical tasks.
Intraoperative fluorescence imaging has reached Stage 3 development in reconstructive surgery but is still in Stage 2 for heart and GI surgeries, indicating varying levels of maturity in its application.
Transmyocardial laser revascularization provides relief for severe angina patients, particularly those suffering from intense chest pain when traditional surgeries are not an option.
Surgical treatment for prosthetic valve endocarditis showed a decrease in in-hospital mortality from 20% to 10% over the years, with an 82% five-year survival rate for patients.
In studying blood flow in dogs, it was found that only 8% of heart regions maintain blood flow reserve at very low pressures during ischemia, highlighting the complexity of heart function during inadequate blood supply.

Plain English This study gathered international experts in fluorescence-guided surgery to agree on best practices for using near-infrared light and a dye called Indocyanine Green (ICG) during surgery. They found that 41 out of 44 statements reached consensus, confirming that this imaging technique is effective and safe for tasks like locating blood vessels and tumors, and assessing tissue health. It matters because it could improve surgical outcomes and patient safety.

Plain English This research paper examined how well intraoperative fluorescence imaging is being used to check blood flow during different types of surgeries. It reviewed 196 studies and found that the use of this imaging method is at different development stages in various surgical fields; for instance, it’s more advanced in reconstructive surgery (Stage 3) but still developing in heart and GI surgeries (Stage 2a and 2b). This is important because while the technique shows promise for improving surgical outcomes, further studies are needed to clearly establish its benefits for patients.

Samuels L, Emery R, Lattouf O, Grosso M, AlZeerah M +4 more
Plain English This research looked at a treatment called transmyocardial laser revascularization (TMR) for patients with severe angina who cannot undergo traditional heart surgeries. The findings showed that TMR can successfully treat these patients, particularly those with intense chest pain, providing relief when other methods have failed. The study emphasizes the importance of carefully planning and considering TMR as a valid option before surgery.
Who this helps: Patients with severe angina who are not suitable candidates for bypass surgery or other interventions.
Surgical treatment of prosthetic valve endocarditis.

The Journal of thoracic and cardiovascular surgery
Lytle BW, Priest BP, Taylor PC, Loop FD, Sapp SK +4 more
Plain English This study examined the outcomes of surgical treatment for infections affecting artificial heart valves, called prosthetic valve endocarditis, in 146 patients over a period from 1975 to 1992. It found that 13% of patients died in the hospital after surgery, but this number decreased from 20% to 10% over the years studied, and about 82% of patients survived for five years post-surgery. The results are significant because they show that while prosthetic valve endocarditis is a serious issue, improvements in surgical techniques and antibiotic treatment have greatly enhanced survival rates.
Who this helps: This benefits patients with artificial heart valves and their doctors.
Nonuniform loss of regional flow reserve during myocardial ischemia in dogs.
1990
Circulation research
Coggins DL, Flynn AE, Austin RE, Aldea GS, Muehrcke D +2 more
Plain English This study looked at how blood flow behaves in different areas of the heart during a lack of oxygen in dogs. Researchers found that while the heart's ability to increase blood flow (known as flow reserve) is present in all areas at higher pressures, it drops significantly at lower pressures: only 8% of regions had this ability at very low pressure. This matters because it shows that not all parts of the heart respond the same way when blood flow is compromised, and highlights the importance of understanding these differences in treating heart conditions.
Who this helps: This research helps doctors better understand heart function during ischemia and can lead to improved treatments for patients with heart disease.
