Insights

Transmyocardial revascularization (TMR) offers significant angina relief for selected severe angina patients unsuitable for bypass surgery. However, this cardiac surgery intervention carries a notable perioperative mortality risk of approximately 5%.

Area of Science:

  • Cardiovascular Surgery
  • Interventional Cardiology

Background:

  • Severe angina pectoris often presents in patients with coronary artery disease unsuitable for traditional bypass grafting.
  • Transmyocardial revascularization (TMR) has been proposed as an alternative therapy for refractory angina in 'no option' patients.

Purpose of the Study:

  • To evaluate the efficacy and safety of transmyocardial revascularization (TMR) in patients with severe angina and ungraftable myocardium.

Main Methods:

  • A systematic review of best-evidence studies was conducted.
  • 345 relevant papers were identified, with 11 selected for detailed analysis.
  • Data on patient characteristics, study design, outcomes, and limitations were tabulated.

Main Results:

  • Transmyocardial revascularization (TMR) significantly reduced angina grade in selected stable patients with CCS grade III-IV angina.
  • The perioperative mortality associated with TMR was approximately 5%.

Conclusions:

  • Transmyocardial revascularization (TMR) is a viable option for select 'no option' patients with severe angina.
  • The benefits of angina reduction must be weighed against the significant perioperative risks.

Angina IV: Management

IntroductionThe management of angina requires a comprehensive approach that includes pharmacological therapies, medical procedures, and lifestyle modifications.Pharmacological TherapiesAntiplatelet agents, such as aspirin, clopidogrel, prasugrel, and ticagrelor, play a pivotal role in preventing thrombus formation in patients with angina. These medications inhibit platelet aggregation and reduce the likelihood of myocardial infarction and other cardiovascular events.Anticoagulants, including...

Angina II: Classification

Angina, also known as angina pectoris, is a chest pain resulting from diminished blood flow to the heart muscle and is often a symptom of coronary artery disease. Angina presents several variants with distinctive attributes, etiologies, and therapeutic approaches. The main types of angina include stable, unstable, variant (Prinzmetal's), microvascular, intractable, and silent ischemia.Stable angina is caused by atherosclerosis, which leads to the formation of plaques that narrow the coronary...
