Can CHD be treated without surgery? 

Author: Harry Whitmore, Medical Student | Reviewed by: Dr. Stefan Petrov, MBBS

While “heart surgery” is often the first thing people associate with Congenital Heart Disease (CHD), a significant number of patients can be treated using non-surgical methods. In 2026, the boundaries between traditional surgery and “interventional” cardiology have blurred. Many structural defects that once required open-chest procedures are now routinely repaired using minimally invasive catheter-based techniques. Furthermore, for some mild or stable conditions, medical management through targeted drug therapies and lifestyle adjustments is sufficient to maintain heart health without ever needing a physical intervention. 

The shift toward non-surgical care is driven by the desire to reduce physical trauma, shorten hospital stays, and avoid the risks associated with the heart-lung bypass machine. According to clinical standards in 2026, roughly 60% of common defects like Atrial Septal Defects (ASD) and Patent Ductus Arteriosus (PDA) are now treated exclusively in the catheterisation lab rather than the operating theatre. This article explores the pharmacological, interventional, and lifestyle-based strategies used to manage CHD without traditional surgery. 

What We’ll Discuss in This Article 

  • Interventional Catheterisation: The “Middle Ground” between medicine and surgery. 
  • Targeted Pharmacological Therapies: 2025-2026 advances in heart failure and hypertension drugs. 
  • “Watchful Waiting”: Why some holes in the heart are left untreated. 
  • The role of lifestyle and preventive care in long-term cardiac wellness. 
  • A data-driven comparison of surgical vs. non-surgical outcomes. 
  • Future trends: RNA-targeted therapies and artery regrowth. 

Interventional Catheterisation: The Minimally Invasive Alternative 

The most common way CHD is treated without “open” surgery is through interventional cardiac catheterisation. In this procedure, a specialist (interventional cardiologist) threads a thin tube through a blood vessel in the groin up to the heart. This allows them to perform complex repairs with high precision. 

  • Device Closures: Using “plugs” or “umbrellas” (like the Amplatzer device) to seal holes such as ASDs or PDAs. Once in place, the heart’s own tissue grows over the device, making it a permanent part of the heart wall. 
  • Balloon Dilation: A balloon is inflated to snap open a narrow valve (Stenosis) or widen a restricted artery (Coarctation). 
  • Transcatheter Valve Replacement: As of 2026, even heart valves can be replaced via catheter, a major breakthrough for patients who have had multiple previous surgeries. 

Pharmacological Management: 2025-2026 Drug Advances 

For many patients, medications are used to manage symptoms, reduce the workload on the heart, or prevent complications like blood clots and infections. Recent breakthroughs have introduced “precision medicine” into CHD care. 

Drug Class Examples (2025/2026) Clinical Purpose 
Endothelin Antagonists Aprocitentan Manages high blood pressure in complex CHD cases. 
SGLT2 Inhibitors Empagliflozin Recently approved for paediatric heart failure symptoms. 
Prostaglandins PGE1 Keeps fetal vessels open in newborns to delay surgery. 
Anti-arrhythmics Sotalol / Flecainide Controls irregular heartbeats caused by structural defects. 
Anti-coagulants Aspirin / Apixaban Prevents clots on devices or in “slow-flow” Fontan circuits. 

The Role of “Watchful Waiting” 

Not every “hole in the heart” needs to be fixed. Many small Atrial Septal Defects (ASD) or muscular Ventricular Septal Defects (VSD) are asymptomatic and pose no threat to a child’s health. In these cases, the “treatment” is regular monitoring with echocardiograms. Clinical data suggests that up to 75% of small muscular VSDs will close naturally before a child reaches school age, making surgery unnecessary and even counter-productive. 

Clinical Data: Surgical vs. Non-Surgical Success 

Choosing a non-surgical path is not a compromise; for many conditions, it is now the superior option. According to a 2022 narrative review in Pediatric MedicineHauck, A., et al. (2025). ‘Current outcomes and future trends in paediatric and congenital cardiac surgery.’, the success rates for catheter-based closures often match or exceed those of traditional surgery for specific lesions. 

Condition Treatment Type Success Rate (2026 Data) Recovery Time 
Secundum ASD Catheter Device 98.5% 1 – 2 Days 
Pulmonary Stenosis Balloon Valvuloplasty 96% 1 Day 
Large VSD Traditional Surgery 99% 7 – 10 Days 
Patent Ductus (PDA) Catheter Coil/Plug 99.2% 1 Day 

To Summarise 

Treatment for CHD does not always mean surgery. While complex structural malformations still require the expertise of a cardiac surgeon, the vast majority of modern CHD care involves a combination of minimally invasive catheter procedures and sophisticated drug therapies. By focusing on “palliative” medicine and lifestyle management such as strict dental hygiene and tailored exercise many patients can avoid the operating theatre entirely while maintaining a quality of life identical to their peers. 

If your child has blue-tinged lips, rapid “grunting” breaths, or seems extremely lethargic, call 999 immediately. 

If you notice a sudden worsening of breathlessness or a persistent, frothy cough, call 999 immediately. 

Can a large hole in the heart be treated without surgery? 

Yes, many large Atrial Septal Defects can be closed using a catheter device. However, some large Ventricular Septal Defects (VSD) still require a surgical patch if the hole is in a difficult location. 

Are there side effects to CHD medications? 

Like all drugs, heart medications can have side effects such as dizziness or upset stomach. Your cardiologist will monitor kidney and liver function regularly to ensure the dose is safe. 

Is “keyhole” surgery the same as a catheter procedure? 

“Keyhole” usually refers to minimally invasive surgery with small incisions between the ribs. Catheter procedures are even less invasive, as they only involve a needle prick in the groin. 

Why does my doctor say my child’s VSD doesn’t need treatment? 

If the hole is small and not causing the heart to enlarge or the lungs to become congested, it is safer to monitor it, as it may close on its own. 

Can adults have non-surgical CHD treatment? 

Absolutely. Many adults are now having heart valves replaced or holes closed via catheterisation, avoiding the risks of “re-do” open-heart surgery. 

What is “RNA-targeted therapy” in CHD? 

It is an emerging field where doctors use genetic technology to treat the biological systems causing heart issues, rather than just the symptoms. 

Does a non-surgical repair last a lifetime? 

Yes, most catheter devices are made of titanium or nitinol and are designed to stay in the heart for a lifetime without needing replacement.
