Transmyocardial Revascularization (TMR) Cost in United Arab Emirates

Transmyocardial Revascularization (TMR) is performed to relieve severe, chronic chest pain (angina) in patients who are not candidates for conventional procedures like angioplasty or coronary artery bypass grafting (CABG). It improves blood flow directly to the heart muscle by creating small channels in the myocardium (heart wall), allowing oxygen-rich blood from the left ventricle to nourish ischemic areas. TMR is especially useful in patients with diffuse coronary artery disease or those with previously failed revascularization attempts.

You should consult a cardiologist if you're experiencing persistent chest pain despite optimal medical therapy, especially if previous stent placement or bypass surgery hasn’t worked or isn’t an option. TMR is typically considered for patients with refractory angina who are at high surgical risk or have complex blockages not amenable to traditional methods.

Preparation for TMR includes a complete cardiac evaluation — such as ECG, echocardiography, coronary angiography, and stress tests — to assess heart function and identify suitable candidates. Patients are advised to fast for several hours before the surgery or procedure and to temporarily stop certain medications as instructed. A detailed consultation will cover the procedure, potential risks, and recovery expectations.

Usually, a powerful CO₂ or Holmium:YAG laser is used for TMR as a minimally invasive treatment or during open heart surgery:

• Hybrid or standalone surgical TMR: After making a tiny incision in the chest, 20–40 tiny channels are formed in the left ventricle wall using a laser. These channels permit blood to enter oxygen-depleted cardiac tissue straight from the ventricle.
• A hybrid strategy: In some situations, if only some coronary arteries can be bypassed and others need TMR, TMR and CABG are combined.

The procedure generally takes one to two hours. Hospitalisation typically lasts 3 to 5 days after standalone TMR, while hybrid TMR with bypass surgery may require a longer stay depending on patient condition and surgical complexity.

• Irregular heart rhythms (arrhythmias)
• Bleeding
• Infection
• Pericardial effusion (fluid around the heart)
• Stroke or heart attack (rare)
• Reaction to anesthesia

• Significant reduction in angina symptoms
• Improved quality of life and exercise tolerance
• Decreased dependence on anti-anginal medications
• Beneficial for patients with no other surgical options
• May promote long-term blood vessel formation (angiogenesis)

Recovery time varies by the type of procedure. After TMR, patients are typically monitored in the ICU for 24–48 hours. Discomfort at the incision site is normal. Physical activity is gradually resumed over weeks. Regular follow-up is essential to monitor heart function and adjust medications.
