Tetralogy of Fallot: Survival Rates and Surgical Outcomes

A diagnosis of Tetralogy of Fallot can be one of the most frightening things a parent hears about their child. This congenital heart condition affects how blood flows through the heart and to the rest of the body, and it requires prompt diagnosis and surgical intervention to give a child the best possible chance at a healthy life. The encouraging news is that with timely detection and repair at an experienced pediatric cardiac center, children with TOF today have high long‑term survival rates and many go on to lead active, productive lives.

If your medical provider missed or delayed a diagnosis that allowed your child's oxygen levels to fall to dangerous levels for an extended period of time you may be able to hold them accountable for any injuries that follow. At The Becker Law Firm, our Cleveland birth injury attorneys are here to help Ohio families determine whether a failure in care contributed to their child's harm.

What Is Tetralogy of Fallot (TOF)?

Tetralogy of Fallot (TOF) is a congenital heart defect, meaning it is present at birth. This defect involves four structural abnormalities that together reduce the amount of oxygenated blood reaching the body. 

Each of the four defects plays a role in disrupting normal cardiac function:

• Ventricular septal defect: A hole in the wall separating the heart's two lower chambers, allowing oxygen-poor and oxygen-rich blood to mix.
• Pulmonary stenosis: A narrowing of the pulmonary valve and the pathway leading to the lungs, which restricts blood flow to where it needs to go to receive oxygen.
• Overriding aorta: A positioning of the aorta that places it over the ventricular septal defect rather than entirely over the left ventricle, pulling deoxygenated blood into circulation.
• Right ventricular hypertrophy: Thickening of the right ventricle's muscular wall, which occurs as the heart works harder to push blood past the narrowed pulmonary valve.

Taken together, these defects mean that your child's body may not be receiving adequate oxygenation. Early detection and timely surgical repair may be needed to prevent prolonged hypoxia and the serious neurological consequences that may follow.

Early Diagnosis: Prenatal and Newborn Screening

TOF can often be identified before birth. A fetal echocardiogram, which is a specialized ultrasound of the developing heart, is the primary tool for prenatal detection, particularly when a routine ultrasound raises concern. 

After birth, pulse oximetry screening, which measures the oxygen saturation in a newborn's blood, is a standard part of newborn care and can identify infants with critically low oxygen levels who require immediate evaluation.

When these screening tools are used appropriately and results are acted upon promptly, children can receive the care they need before serious harm occurs. 

However, providers may:

• Fail to order or perform fetal echocardiography when indicated
• Dismiss or misinterpret abnormal findings on prenatal imaging
• Ignore low pulse oximetry readings in a newborn
• Delay referral to a pediatric cardiologist

In which case, the window for intervention can close. Prolonged oxygen deprivation in a newborn can lead to cyanotic episodes, seizures, stroke, or permanent neurological injury including hypoxic-ischemic encephalopathy (HIE) and cerebral palsy. Following standard cardiac screening protocols is part of the accepted standard of care, and departures from those protocols can become central to a birth injury claim.

Surgical Repair and Long-Term Survival Rates

The primary treatment for TOF is open-heart surgery to correct the underlying structural defects. In many cases, repair is performed during infancy. 

Most children who undergo timely and successful repair go on to live active lives, though ongoing cardiology follow-up is important throughout childhood and into adulthood. Some individuals may require additional procedures or re-interventions over time, particularly related to the pulmonary valve, but these are generally manageable with appropriate monitoring and care.

Preventable Injury When Standard Protocols Are Not Followed

It is important to understand that a TOF diagnosis is not, by itself, evidence of malpractice. TOF is a known and recognized congenital heart condition. What may lead to a legal claim is whether providers followed accepted diagnostic and treatment standards, and what happened if they did not.

Examples of improper standard of care in TOF cases can include:

• Failure to perform or properly interpret fetal echocardiography when a screening ultrasound raised a cardiac concern.
• Ignoring abnormal oxygen saturation readings on newborn pulse oximetry.
• Delaying referral to a pediatric cardiologist after warning signs were present.
• Postponing surgical repair in a clinically unstable infant when intervention was warranted.
• Inadequate monitoring of a known or suspected cardiac condition in the prenatal or neonatal period.

When these lapses result in a period of prolonged oxygen deprivation, the consequences may include cardiac arrest, stroke, seizures, and permanent neonatal brain injury. These are outcomes that may have been prevented with appropriate, timely care. If the appropriate level of care was not present, you may have a medical malpractice claim.

How Birth Injury and Medical Malpractice Lawyers Investigate TOF Cases

Cases involving delayed diagnosis or mismanaged treatment of TOF require a careful review of medical records. At The Becker Law Firm, our birth injury attorneys and medical malpractice lawyers work with qualified pediatric cardiologists and neurologists to analyze records including:

• Prenatal ultrasound and echocardiography reports
• Newborn pulse oximetry results and nursing notes
• Pediatric cardiology consultation notes
• NICU progress notes and monitoring data
• Surgical reports and postoperative records
• Neuroimaging studies ordered after a suspected hypoxic event

When the evidence supports a medical malpractice claim, The Becker Law Firm works to secure the resources families need to fund ongoing medical care, therapy, educational support, and the long-term costs of raising a child with a serious neurological injury. Call us today at 216-480-4620 to get the help you need.

Acting Quickly When a Child's Care May Have Been Substandard

Ohio law imposes strict statutes of limitations on medical malpractice and birth injury claims, typically one year from the date of malpractice or one year from when the injury was (or should have been) discovered, with a general four-year cap from the incident date. Families who wait too long risk permanently losing their right to pursue compensation, regardless of case merits.

Acting promptly after a suspected delay in diagnosis or treatment serves several critical purposes:

• Medical records, imaging studies, and monitoring data can be preserved before they become unavailable
• Expert witnesses can be identified and engaged while the facts are still fresh
• Attorneys have adequate time to conduct a thorough and well-supported case evaluation

If your child was diagnosed with Tetralogy of Fallot and suffered a stroke, seizures, or brain injury after what you believe was a delayed or missed diagnosis, a legal consultation can help clarify whether you have grounds for a claim. There is no cost to speak with us and no obligation to proceed.
