Open Heart Surgery: Procedures, Preparation, Recovery Timeline, Risks, and Long-Term Care

Open heart surgery involves opening the chest to operate on the heart muscle, valves, arteries, or aorta. It's performed for life-threatening or quality-of-life-limiting conditions. Modern outcomes are excellent.

Common Procedures

• Coronary Artery Bypass Grafting (CABG): Grafts (vein/artery) bypass blocked coronary arteries. Most common cardiac surgery.
• Valve Repair/Replacement: Mitral, aortic, tricuspid, pulmonic. Mechanical vs. bioprosthetic valves.
• Aortic Surgery: Ascending/arch/descending aneurysm repair, dissection repair, root replacement.
• Congenital defect repair: ASD, VSD, Tetralogy of Fallot, etc.
• Heart transplant / VAD implantation: End-stage heart failure.
• Maze procedure: Surgical ablation for AFib (often combined with other surgery).

Preoperative Preparation

• Comprehensive evaluation: cath, echo, CT, pulmonary function, carotid ultrasound, dental clearance.
• Optimize medical conditions: diabetes, anemia, COPD, renal function.
• Smoking cessation ≥4 weeks (reduces pulmonary/wound complications).
• Medication adjustments: hold anticoagulants, SGLT2 inhibitors, certain herbals.
• Prehab: exercise, nutrition, breathing exercises (incentive spirometry).
• Informed consent: risks, benefits, alternatives, blood transfusion discussion.

Surgical Procedure

• Median sternotomy (standard) or minimally invasive approaches (mini-thoracotomy, robotic).
• Cardiopulmonary bypass (heart-lung machine) with cardioplegic arrest (most cases).
• Off-pump (beating heart) CABG for selected patients.

Postoperative Course

• ICU (1–3 days): Ventilator wean, hemodynamic monitoring, pacing wires, chest tubes, insulin drip, early mobilization.
• Step-down/floor (3–7 days total): Progressive ambulation, oral meds, wound care, education.
• Discharge criteria: Stable vitals, oral intake, pain controlled on PO meds, independent ADLs, no fever, bowel function.

Recovery Timeline

• 6–8 weeks: Sternotomy healing (no lifting >10 lbs, no driving).
• Cardiac rehab (Phase II): Supervised exercise 3×/week × 12 weeks—improves mortality, QoL.
• 3–6 months: Full functional recovery.

Risks and Complications

• Bleeding, transfusion
• Infection (sternal wound, mediastinitis, sepsis)
• Stroke, neurocognitive decline
• Arrhythmias (post-op AFib 20–40%)
• Renal failure
• Graft/valve failure
• Depression, anxiety (common)

Long-Term Follow-Up

• Lifelong cardiology surveillance.
• Secondary prevention: statin, antiplatelet, BP control, diabetes management, lifestyle.
• Valve surveillance (echo) if bioprosthetic (structural deterioration 10–15 yr).

Modern outcomes are excellent: CABG operative mortality 1–2%; valve surgery 2–3%. Shared decision-making with heart team essential.
