Beating Heart Surgery (Off-Pump CABG)
Coronary bypass performed on a beating heart — avoiding the heart-lung machine
Overview
Beating heart surgery, medically known as Off-Pump Coronary Artery Bypass Grafting (OPCAB), is a specialized technique for performing coronary bypass surgery while the heart continues to beat naturally. Unlike traditional CABG where the heart is stopped and a heart-lung machine takes over circulation, OPCAB avoids the use of cardiopulmonary bypass entirely.
This technique eliminates the potential complications associated with the heart-lung machine, including systemic inflammatory response, blood cell damage, and the risk of stroke from aortic manipulation. Dr. Nisarga performs nearly 99% of his coronary bypass surgeries using the off-pump technique whenever clinically appropriate.
Using specialized mechanical stabilizers, the specific area of the heart where the bypass graft needs to be attached is immobilized, allowing precise suturing while the rest of the heart continues to beat and function normally.

Conditions Treated
Beating Heart Surgery (Off-Pump CABG) is used to treat the following conditions
Multi-Vessel Coronary Disease
Blockages requiring bypass in multiple coronary territories
Left Main Coronary Artery Disease
Critical narrowing of the main coronary artery
Porcelain Aorta
Heavily calcified aorta where clamping poses high stroke risk
Chronic Kidney Disease
Patients who may be adversely affected by the heart-lung machine
Severe Lung Disease
Patients with COPD or other pulmonary conditions
High-Risk Surgical Candidates
Elderly or frail patients who may benefit from avoiding bypass
Symptoms
Patients with conditions requiring Beating Heart Surgery may experience one or more of the following symptoms. It is important to note that some conditions may be asymptomatic in their early stages.
Important: These symptoms can also be caused by other medical conditions. If you experience any of these symptoms, please consult a qualified healthcare professional for an accurate diagnosis.
Diagnosis
A thorough diagnostic evaluation is essential for accurate diagnosis and treatment planning
Treatment Options
The choice of treatment depends on the specific condition, its severity, and individual patient factors
Optimal Medical Therapy
Aggressive medical management of coronary disease
Stent Placement (PCI)
Percutaneous coronary intervention for suitable lesions
Off-Pump CABG (Beating Heart)
Bypass surgery without the heart-lung machine
On-Pump CABG
Traditional bypass with cardiopulmonary bypass support
Hybrid Revascularization
Combination of bypass surgery and stenting
Surgical Approach
How the procedure is performed by Dr. Nisarga and his team
A median sternotomy (midline chest incision) is typically performed to access the heart.
The internal mammary artery is carefully harvested from the chest wall, along with other grafts from the leg or arm.
Specialized mechanical stabilizers are positioned to immobilize the specific area of the heart being grafted.
The beating heart is positioned using a pericardial cradle and stabilizer to expose the target coronary artery.
A temporary shunt or blower may be used to maintain a clear surgical field while the artery is opened.
The bypass graft is meticulously sutured to the coronary artery while the heart continues to beat.
Each graft is checked for adequate flow using transit-time flow measurement before completion.
The procedure is repeated for each coronary artery requiring bypass.

A Word from Dr. Nisarga
While beating heart surgery avoids the heart-lung machine, it still typically requires a full sternotomy. For selected patients with appropriate coronary anatomy, Dr. Nisarga may combine off-pump techniques with minimally invasive or robotic approaches for a less invasive bypass procedure. This hybrid approach offers the benefits of avoiding both sternotomy and cardiopulmonary bypass.
