Start with what you need treated.

Aortic aneurysm repair treats an abnormal dilation of the aorta that carries a significant risk of rupture if left untreated. Depending on the aneurysm's size, location, and the patient's overall health, repair may be done through open surgery, where the weakened segment is replaced with a synthetic graft, or through a minimally invasive endovascular approach using a stent graft delivered via catheter. Open repair is more invasive and typically requires several hours under general anesthesia, while endovascular repair has a shorter recovery time. Patients are monitored closely after surgery for bleeding, kidney function, and graft position. Regular imaging follow-up is required, especially after endovascular repair, to ensure the graft remains well-positioned and the aneurysm does not continue to grow.

Aortic dissection repair is an emergency procedure performed when the inner layer of the aortic wall tears, allowing blood to flow between the layers and potentially rupture the vessel or block blood supply to vital organs. Surgery involves removing the damaged section of aorta and replacing it with a synthetic graft, sometimes along with repair or replacement of the aortic valve if involved. The operation requires cardiopulmonary bypass and often deep hypothermic circulatory arrest to safely work on the aortic arch, typically taking five to eight hours. Patients require intensive postoperative monitoring for organ function, bleeding, and neurological status. Recovery is prolonged, often taking several months, given the severity of the underlying emergency. Long-term blood pressure control and imaging surveillance are essential to prevent further complications.

Aortic stent grafting, or endovascular aneurysm repair (EVAR), treats aortic aneurysms or certain dissections without the need for open chest or abdominal surgery. A catheter delivers a compressed stent graft to the affected segment of the aorta, where it expands to line the vessel wall and redirect blood flow away from the weakened area, reducing pressure on the aneurysm sac. The procedure is performed under fluoroscopic guidance and typically takes two to three hours. Recovery is significantly faster than open surgery, with most patients mobilizing within a day. Regular follow-up imaging, usually with CT scans, is necessary to confirm the graft remains properly positioned and the aneurysm is stable or shrinking. It is preferred in patients with suitable anatomy and higher surgical risk.

The arterial switch operation is the definitive corrective surgery for transposition of the great arteries, performed in the neonatal period. The surgeon detaches the aorta and pulmonary artery from their abnormal positions and reattaches each to the correct ventricle, along with reimplanting the coronary arteries into the new aortic root. This complex operation is performed under general anesthesia using cardiopulmonary bypass and typically takes four to six hours. The infant recovers in a pediatric cardiac intensive care unit with close monitoring of heart function and coronary blood flow. Outcomes are generally excellent with modern surgical techniques, allowing normal growth and development. Lifelong cardiology follow-up is recommended to monitor heart and coronary artery function.

This device combines the benefits of cardiac resynchronization therapy and defibrillator protection with technology that allows patients to safely undergo MRI scans when medically necessary, which is important for those needing ongoing imaging for other conditions. Leads are placed in the heart chambers to coordinate ventricular contraction, while the pulse generator is positioned in a subcutaneous pocket near the collarbone. The implant procedure takes about one to two hours under local anesthesia with sedation. Patients are monitored overnight with imaging to confirm correct lead placement. Device settings are optimized over subsequent visits to maximize symptom relief. This MRI-compatible option provides greater flexibility for long-term patient care without compromising cardiac protection.

Fetal echocardiography is a detailed ultrasound examination used to assess the fetal heart's anatomy, rhythm, and function, typically performed between 18 and 24 weeks of pregnancy in high-risk pregnancies or when a routine scan raises concern. A trained specialist uses ultrasound to visualize the heart's chambers, valves, and major blood vessels in detail. The test is completely non-invasive, requires no special preparation, and is usually completed within 30 to 60 minutes. There is no discomfort for the mother or risk to the baby. Detecting a congenital heart defect before birth allows the medical team to plan appropriate delivery and postnatal care. Early diagnosis often significantly improves outcomes for babies who need treatment after birth.

Interrupted aortic arch is a severe congenital heart defect where the aorta lacks continuity between its ascending and descending portions, and surgical repair is required urgently after birth to restore normal circulation. The operation involves reconnecting the interrupted segments, often along with closure of an associated ventricular septal defect, using cardiopulmonary bypass and sometimes deep hypothermic circulatory arrest. This is a highly complex neonatal surgery typically lasting several hours and carried out by a specialized pediatric cardiac surgical team. The newborn is cared for in intensive care after surgery, with careful monitoring of blood pressure and organ perfusion. Long-term outcomes have improved considerably with advances in neonatal cardiac surgery. Lifelong specialized cardiology follow-up is required to monitor for arch narrowing or other late complications.

Myocardial perfusion imaging assesses how well blood flows through the heart muscle under both resting and stress conditions, typically induced by exercise or medication. A radioactive tracer is injected and images are captured using a special camera, first after stress and again at rest, to compare blood flow patterns. Reduced tracer uptake during stress that improves at rest suggests a reversible blockage, while a persistent defect may indicate prior heart damage. The test takes a few hours in total, including preparation and imaging phases, but involves no incisions and only mild discomfort from the intravenous line. Patients can resume normal activities immediately afterward. Results help cardiologists decide whether further intervention such as angioplasty is warranted.

PDA device closure treats a patent ductus arteriosus, a fetal blood vessel connection that normally closes shortly after birth but sometimes remains open, causing extra strain on the heart and lungs. A catheter is used to deliver a small coil or occluder device to the ductus, sealing it and stopping abnormal blood flow between the aorta and pulmonary artery. The procedure is performed under sedation or light general anesthesia and typically takes 30 to 60 minutes. Patients are monitored for a few hours to overnight to confirm correct device position and heart rhythm stability. Most children resume normal activity within a day or two. This minimally invasive approach has largely replaced open surgical closure for the vast majority of cases.

A single-chamber permanent pacemaker is used in patients whose heart rate is too slow due to problems limited to one chamber, most commonly the ventricle, or in select cases with chronic atrial fibrillation. A single lead is threaded through a vein into the appropriate heart chamber and connected to a pulse generator placed under the skin near the collarbone. The procedure is performed under local anesthesia and generally takes under an hour. A chest X-ray and device interrogation confirm proper placement before the patient goes home. Patients are advised to limit arm movement on the implant side for a few weeks to allow the leads to settle. Routine follow-up visits monitor device function and battery status over the years.

Renal vein thrombosis occurs when a blood clot forms in the vein that drains blood from the kidney, which can impair kidney function and, if a piece breaks off, cause a pulmonary embolism. Treatment usually begins with anticoagulant medication to prevent clot extension and allow the body to gradually dissolve it, with regular blood tests to monitor the therapeutic effect. In severe or rapidly worsening cases, catheter-directed thrombolysis or clot retrieval may be performed to restore blood flow more quickly. Investigations are also carried out to identify underlying causes such as nephrotic syndrome or clotting disorders. Kidney function is closely monitored throughout treatment with blood tests and imaging. Most patients recover kidney function well with prompt and appropriate treatment.

The Ross procedure is used to treat aortic valve disease, particularly in children, young adults, and active patients who wish to avoid lifelong blood thinners required with mechanical valves. The surgeon moves the patient's own healthy pulmonary valve into the aortic position, since it can better withstand higher pressures, and replaces the vacated pulmonary valve position with a donor or synthetic conduit. This complex double-valve operation is performed under general anesthesia using cardiopulmonary bypass and typically takes five to seven hours. The patient's own living aortic valve substitute can grow with the child and does not require blood thinners. Recovery follows a similar course to other open-heart valve surgeries, with several weeks needed for full healing. Long-term follow-up monitors both the new aortic and pulmonary valve positions.
