Heart Surgery Types and Risks

06 Feb, 2024

Heart surgery, also known as cardiac surgery, refers to a variety of treatments done on the heart or surrounding blood arteries to treat illnesses such as coronary artery disease, valve defects congenital defects, and heart failure. Coronary artery bypass grafting (CABG) is used to restore blood flow, as well as to repair or replace heart valves, correct congenital defects, and perform heart transplants in severe heart failure patients. These procedures need specific expertise and modern equipment and are often performed in specialist cardiac hospitals by skilled surgeons. Despite the inherent risks such operations considerably improve patients’ quality of life and prognosis, often relieving symptoms, enhancing heart function, and increasing life expectancy. Here we will explore about heart surgery types and risks.

Types of Heart Surgery

Coronary artery bypass grafting (CABG): Coronary artery bypass grafting (CABG), sometimes known as “heart bypass surgery,” is an extremely important operation in the treatment of coronary artery disease. This surgery involves creating new channels for blood flow around blocked or narrowed coronary arteries. Surgeons use healthy blood arteries, usually from the patient’s own body, to bypass the blocked segments and restore enough blood flow to the heart muscle. CABG seeks to relieve symptoms such as chest discomfort (angina) and improve overall cardiac function, therefore lowering the risk of unfavorable cardiovascular events.
Heart Valve Repair or Replacement: Heart valve repair or replacement treatments are essential in treating a variety of irregularities affecting the heart valves, which are responsible for controlling blood flow inside the heart chambers. Surgeons carefully repair or replace damaged valves using mechanical or biological replacements made from animal or human tissue. These treatments aim to regain proper valve function, promote efficient blood circulation, and reduce symptoms associated with valve dysfunction such as shortness of breath, exhaustion, and palpitations.
Aneurysm repair: These procedures repair weakening arteries or heart walls, preventing serious ruptures. Patch grafting and endovascular stent grafting are two techniques used to strengthen these regions and restore normal blood flow. This surgery lowers the chance of problems like internal bleeding, which benefits overall cardiovascular health.
Arrhythmia surgery: It addresses abnormal heart rhythms that may negatively impact cardiac function and quality of life. Pacemaker implantation, implanted cardioverter defibrillator (ICD) installation, and Maze surgery all cause scar tissue to change electrical circuits in the heart, restoring rhythm stability and lowering the risk of life-threatening arrhythmias.
Heart failure treatments: They attempt to reduce symptoms and improve outcomes for those with reduced heart function. Interventions may involve introducing devices such as ventricular assist devices (VADs) or complete artificial hearts (TAHs) to improve heart function and circulation. Also, heart transplantation may provide a cure for serious cases, considerably enhancing the quality of life for individuals who are suitable candidates.

Risks Associated with Heart Surgery

Bleeding and Infection: Despite all precautions, bleeding, and infection at the surgical site are common risks of any surgery, including cardiac surgeries.
Anesthesia Reactions: The use of anesthesia can result in many kinds of painful reactions, ranging from allergic reactions to anesthesia medication problems.
Organ damage: During surgery, important organs such as the heart, kidneys, liver, and lungs could suffer unintended harm.
Stroke: Disruption of blood flow during surgery can cause blood clot development, increasing the risk of a stroke.
Mortality: Although uncommon, there is a slight risk of mortality linked with cardiac surgery. This risk is increased in high-risk patients or emergency procedures, despite improvements in surgical techniques and post-operative care.

Advancements in Heart Surgery in India

Open-heart surgery: This standard procedure includes making a midline incision in the chest, which allows direct access to the heart. During the surgery, a heart-lung bypass machine is commonly used to maintain circulation while the heart is momentarily shut down.
Off-pump bypass surgery: Off-pump bypass surgery, sometimes known as “beating heart” surgery, does not need the use of a heart-lung bypass machine. It’s suitable for some types of coronary artery bypass grafting (CABG) surgeries.
Minimally Invasive Approaches: Minimally invasive procedures, such as transcatheter aortic valve implantation (TAVI), can minimize surgical stress and recovery time. These approaches use tiny incisions and catheter-based treatments, providing less invasive options for valve replacements and other surgeries.
Robotic-Assisted Surgery: Robotic technologies provide surgeons with precision control over difficult cardiac operations. Robotic-assisted surgery decreases problems and improves results through enhanced dexterity and vision, especially in mitral valve replacements and other complex procedures.
Specialized High-Volume Hospitals: High-volume hospitals that specialize in cardiac surgery provide comprehensive treatment and expertise. These hospitals have modern facilities and experienced staff and offer the best possible outcomes by focusing on a high number of cardiac cases and giving individual attention to each patient.

The average cost of heart surgery in India is between $1800 and $6000, making it greatly less expensive than in many other nations. Despite the cheaper cost, the success rate of cardiac bypass surgery in India is very high, at around 98%. This success rate is higher than that of many other nations, demonstrating the quality and efficacy of cardiac treatment provided in India. The combination of low prices and great success rates has made India a popular destination for anyone looking for high-quality cardiac surgery solutions. This availability of world-class medical competence, along with positive outcomes, has made India a top choice for patients seeking cardiac treatments both domestically and internationally.

Despite the inherent difficulties, heart surgery provides hope and the prospect of a brighter future for many people. Survival rates for many cardiac surgeries in India are improving as medical technology, surgical techniques, and postoperative care develop. Patients having mitral valve repair, aortic valve replacement, or coronary artery bypass surgery can be comforted by their care team’s competence and commitment to quality in cardiac care.
