Ebstein's cardiophysiology typically presents as an (antidromic) AV reentrant tachycardia with associated pre-excitation. In this setting, the preferred medication treatment agent is procainamide. Since AV-blockade may promote conduction over the accessory pathway, drugs such as beta blockers, calcium channel blockers, and digoxin are contraindicated.

If atrial fibrillation with pre-excitation occurs, treatment options include procainamide, flecainide, propafenone, dofetilide, and ibutilide, since these medications slow conduction in the accessory pathway causing the tachycardia and should be administered before considering electrical cardioversion. Intravenous amiodarone may also convert atrial fibrillation and/or slow the ventricular response.

The Canadian Cardiovascular Society (CCS) recommends surgical intervention for these indications:

- Limited exercise capacity (NYHA III-IV)

- Increasing heart size (cardiothoracic ratio greater than 65%)

- Important cyanosis (resting oxygen saturation less than 90% - level B)

- Severe tricuspid regurgitation with symptoms

- Transient ischemic attack or stroke

The CCS further recommends patients who require operation for Ebstein's anomaly should be operated on by congenital heart surgeons who have substantial specific experience and success with this operation. Every effort should be made to preserve the native tricuspid valve.

People with atrial fibrillation and rapid ventricular response are often treated with amiodarone or procainamide to stabilize their heart rate. Procainamide and cardioversion are now accepted treatments for conversion of tachycardia found with WPW. Amiodarone was previously thought to be safe in atrial fibrillation with WPW, but after several cases of ventricular fibrillation, it is no longer recommended in this clinical scenario.

AV node blockers should be avoided in atrial fibrillation and atrial flutter with WPW or history of it; this includes adenosine, diltiazem, verapamil, other calcium channel blockers, and beta blockers. They can exacerbate the syndrome by blocking the heart's normal electrical pathway (therefore favoring 1:1 atrial to ventricle conduction through the pre-excitation pathway, potentially leading to unstable ventricular arrhythmias).

The definitive treatment of WPW is the destruction of the abnormal electrical pathway by radiofrequency catheter ablation. This procedure is performed by cardiac electrophysiologists. Radiofrequency catheter ablation is not performed in all individuals with WPW because inherent risks are involved in the procedure. When performed by an experienced electrophysiologist, radiofrequency ablation has a high success rate. Findings from 1994 indicate success rates of as high as 95% in people treated with radiofrequency catheter ablation for WPW. If radiofrequency catheter ablation is successfully performed, the condition is generally considered cured. Recurrence rates are typically less than 5% after a successful ablation. The one caveat is that individuals with underlying Ebstein's anomaly may develop additional accessory pathways during progression of their disease.

Taussig–Bing syndrome (after Helen B. Taussig and Richard Bing) is a cyanotic congenital heart defect in which the patient has both double outlet right ventricle (DORV) and subpulmonic ventricular septal defect (VSD).

In DORV, instead of the normal situation where blood from the left ventricle (LV) flows out to the aorta and blood from the right ventricle (RV) flows out to the pulmonary artery, both aorta and pulmonary artery are connected to the RV, and the only path for blood from the LV is across the VSD. When the VSD is subpulmonic (sitting just below the pulmonary artery), the LV blood then flows preferentially to the pulmonary artery. Then the RV blood, by default, flows mainly to the aorta.

The clinical manifestations of a Taussig-Bing anomaly, therefore, are much like those of dextro-Transposition of the great arteries (but the surgical repair is different). It can be corrected surgically also with the arterial switch operation (ASO).

It is managed with Rastelli procedure.

Patients who are diagnosed with AAOCA at or before age 30 years are eligible for this study. They should have otherwise normal heart or only minor defects such as Atrial septal defect, Ventricular septal defect, Patent ductus arteriosus, bicuspid aortic valve, mild pulmonary stenosis etc.

Patients who have other major heart problems that require operations are currently not included in this Cohort study. Any other problems with coronary arteries are also not included.

Crisscross heart is a type of congenital heart defect where the right atrium is closely associated with the left ventricle in space, and the left atrium is closely associated with the right ventricle.

Although it is classified as a defect, the criss-cross is more of a spatial anomaly than a functional one, and it is possible for the heart to have relatively normal functioning.

Anomalous origin of the right coronary artery originating from the pulmonary trunk (ARCAPA) is a rare but potentially fatal anomaly. The goal of surgical therapy is establishment of a physiologic bi-coronary circulation.

The surgical treatment involves the resection of the extracranial venous package and ligation of the emissary communicating vein. In some cases of SP, surgical excision is performed for cosmetic reasons. The endovascular technique has been described by transvenous approach combined with direct puncture and the recently endovascular embolization with Onyx.

Surgical repair is performed. Reconstruction or ligation of aberrant right subclavian artery by sternotomy/by neck approach.

Simple surgical excision is curative. The recommended treatment is that the skin is peeled off the extra-auricular tissue and protruding cartilage remnants are trimmed. Normal appearance is achieved in majority of cases. The reconstruction successful in true cases of accessory auricle, as it also is in individuals with auricular appendages.

There is no known specific treatment for this condition. Management is supportive.

Treatment is only necessary if the degree of curvature is sufficient to cause disability or if it causes emotional distress. Splinting does not routinely correct the deformity. Surgical treatments are closing wedge osteotomy, opening wedge osteotomy, and reversed wedge osteotomy. Radiographs of the fingers are useful in planning the surgical procedure. Severe clinodactyly may require soft tissue alterations to the digit such as release of skin, extensor tendon relocation, and collateral ligament advancement.

Pancreas divisum in individuals with no symptoms does not require treatment. Treatment of those with symptoms varies and has not been well established. A surgeon may attempt a sphincterotomy by cutting the minor papilla to enlarge the opening and allow pancreatic enzymes to flow normally. During surgery, a stent may be inserted into the duct to ensure that the duct will not close causing a blockage. This surgery can cause pancreatitis in patients, or in rare cases, kidney failure and death.

An association with adenoma of the minor papilla has been reported.

Congenital stenosis of vena cava is a congenital anomaly in which the superior vena cava or inferior vena cava has an aberrant interruption or coarctation.

In some cases, it can be asymptomatic, and in other cases it can lead to fluid accumulation and cardiopulmonary collapse.

Typically, treatment for this condition requires a team of specialists and surgery. Below are the treatments based on the symptom.

Anomalous left coronary artery from the pulmonary artery (ALCAPA or Bland-White-Garland syndrome or White-Garland syndrome) is a rare congenital anomaly in which the left coronary artery (LCA) branches off the pulmonary artery instead of the aortic sinus. After birth, the pressure in other coronary arteries (namely the RCA) will have a pressure that exceeds the LCA and collateral circulation will increase. This, ultimately, can lead to blood flowing from the RCA into the LCA (retrograde) and into the pulmonary artery, thus forming a left-to-right shunt.

The syndrome is named for Edward Franklin Bland, Paul Dudley White, and Joseph Garland.

There is currently recruitment for a clinical trial at Boston's Children Hospital.

Three findings are enlarged right ventricular cavity without apical trabeculation with a thin hypokinetic ventricular wall.

Although rare, this condition is often treatable with surgery. In most cases, the blind hemivagina is opened, and the fluid drained.

Treatment of all categories of congenital clasped thumbs should start with either serial plaster casting or wearing a static or dynamic splint for a period of six months, while massaging the hand. Extension by splinting shows reduction of the flexion contracture. To gain optimal results, it is important to start this treatment before the age of six months. The result of this therapy is better in less severe deformities. In most uncomplicated cases, a satisfactory result can be gained when splint therapy starts before the age of six months. Splinting should be tried for at least three months and possibly for as long as six months or longer. If the result of splint therapy stagnates, surgery treatment is indicated.

Uhl's anomaly was first described in 1952 by Dr. Henry Uhl (1921–2009) upon examining one of his patients. It is a very rare congenital heart disease (less than 100 cases 1900–1993) with a partial or total loss of the myocardial muscle in the right ventricle.

Treatment of congenital clasped thumb includes two types of therapy: conservative and surgical.

Surgery

Surgical intervention is warranted in patients who present with new onset neurological signs and symptoms or have a history of progressive neurological manifestations which can be related to this abnormality. The surgical procedure required for the effective treatment of diastematomyelia includes decompression (surgery) of neural elements and removal of bony spur. This may be accomplished with or without resection and repair of the duplicated dural sacs. Resection and repair of the duplicated dural sacs is preferred since the dural abnormality may partly contribute to the "tethering" process responsible for the symptoms of this condition.

Post-myelographic CT scanning provides individualized detailed maps that enable surgical treatment of cervical diastematomyelia, first performed in 1983.

Observation

Asymptomatic patients do not require surgical treatment. These patients should have regular neurological examinations since it is known that the condition can deteriorate. If any progression is identified, then a resection should be performed.

Treatment is only required if the occlusion or bite of the person is compromised and causing other dental problems. Multiple long-term clinical problems can arise such as occlusal interferences, aesthetic disturbances, loss of pulp vitality, irritation of tongue during mastication and speech, caries and displacement of the affected tooth. Most people with talon cusp will live their normal lives unless the case is severe and causes a cascade of other dental issues that lead to additional health problems. This dental anomaly would not be considered fatal. Generally talon cusps on lower teeth require no treatment, but talon cusps on upper teeth may interfere with the bite mechanics and may need to be removed or reduced.

Small talon cusps that produce no symptoms or complication for a person can remain untreated. However large talon cusps should not.

Some common treatments include:

- Fissure sealing

- Composite resin restoration

- Reduction of cusp

- Pulpotomy

- Root canal (endodontic treatment)

- Extraction

The condition is usually benign, but it can cause mild irritation to soft tissues around the teeth and the tongue, and if large enough, may pose an aesthetic problem. Talon cusps that are too large are filed down with a motorized file, and then endodontic therapy is administered.

In order to prevent any future dental complications, when talon cusp is present due to an early diagnosis it would be best to see a dentist regularly every six months for routine dental checkups, remain under observation, brush and floss properly and undergo regular topical applications of fluoride gel to prevent caries and to promote enamel strength.
