Aortic dissection requires absolute emergency surgical replacement of the torn aorta with a synthetic graft.
Hypoplastic left heart syndrome (HLHS) demands a complex series of three staged open-heart surgeries in infants.
Tetralogy of Fallot (ToF) requires surgical closure of the VSD and widening of the pulmonary valve.
Transposition of the great arteries (TGA) needs a highly intricate neonatal arterial switch operation.
Endocarditis (complicated) demands emergency removal of infected heart valves and prosthetic replacement.
Coronary Artery Disease (CAD) requires Coronary Artery Bypass Grafting (CABG) surgery.
Atrial/Ventricular Septal Defects (ASD/VSD) need surgical patch closure to prevent heart failure.
Valvular Heart Disease (Mitral/Aortic stenosis or regurgitation) requires surgical repair or replacement.
Coarctation of the Aorta requires surgical resection of the narrowed segment.
Lung Tumors/Cancer demand precise thoracic resection (lobectomy or pneumonectomy).
Pericardial Effusion/Tamponade requires emergency surgical drainage (pericardial window).
Congenital Pediatric Heart Surgery: Precision structural repairs for infants born with severely defective hearts (blue baby syndromes), completely rearranging the major blood vessels to restore normal oxygenation.
Adult Cardiac & Aortic Surgery: Rapid-response, life-saving interventions for terrifying vascular emergencies (like a tearing aorta) and complex coronary bypass operations.
Complex Thoracic Surgery: Expert surgical management of the lungs, esophagus, and chest wall, extending beyond the heart itself.
An aortic dissection is a catastrophic tearing of the inner layer of the body's main artery. Blood surges through the tear, splitting the artery layers apart. Without immediate surgery, it is rapidly fatal. Dr. Shahidullah places the patient on a heart-lung machine, drastically cools their body to protect the brain, cuts out the torn section of the aorta, and sews in a durable synthetic Dacron tube graft to save the patient's life.
In babies born with Transposition of the Great Arteries (TGA), the two main arteries leaving the heart are connected to the wrong chambers, pumping unoxygenated blood to the body. Dr. Shahidullah performs the incredibly delicate "Arterial Switch"—detaching the aorta and pulmonary artery, moving the microscopic coronary arteries, and reattaching everything in the correct anatomical position, completely curing the child.
Infective endocarditis is a severe bacterial infection of the heart valves. When it becomes "complicated," large clumps of bacteria (vegetations) eat through the valve, causing acute heart failure or breaking off to cause massive strokes. Dr. Shahidullah performs emergency open-heart surgery to cut out the infected, destroyed valve tissue, clean the heart chambers, and sew in a new mechanical or biological tissue valve.
A severe, rare congenital heart defect where the left side of the heart (which normally pumps oxygenated blood to the body) is critically underdeveloped and unable to function. Without intervention, it is fatal within days of birth. It cannot be "fixed" with one surgery. Dr. Shahidullah coordinates a grueling, three-stage surgical palliation path (Norwood, Glenn, and Fontan procedures) over the child's first few years of life to re-route blood flow so the right side of the heart does all the work.
The most common cause of "blue baby syndrome." It involves four simultaneous heart defects: a large hole between the lower chambers (VSD), a narrowed pulmonary valve, an overriding aorta, and a thickened right ventricle. When the child cries or feeds, they turn deeply blue (cyanotic) due to a lack of oxygen. Surgical repair involves placing a patch over the hole and physically widening the pathway to the lungs.
A profound medical emergency often triggered by uncontrolled high blood pressure or genetic connective tissue disorders (like Marfan syndrome). The patient experiences a sudden, excruciating, tearing pain in the chest that radiates straight to the back between the shoulder blades. Every hour that passes without surgical intervention increases the mortality rate by 1-2%.
Dr. AYM Shahidullah utilizes over 15 years of profound surgical wisdom, navigating the razor-thin margins of error in cardiovascular surgery. His philosophy emphasizes absolute surgical precision, extremely rapid emergency triage for adult aortic and infectious crises, and deeply compassionate, multidisciplinary support for parents handing over their critically ill newborns for life-altering congenital heart reconstructions.
Emergency Callout: Immediate emergency medical evaluation is required if a patient experiences sudden, tearing, or ripping chest pain that shoots to the back (Aortic Dissection), a newborn baby suddenly turns dark blue around the lips and severely struggles to breathe during feeding or crying (Congenital Heart Defect crisis), or a patient with a known heart murmur develops a high, unremitting fever with sudden severe shortness of breath (Acute Complicated Endocarditis).

Bring all prior echocardiograms (Echo), Cardiac MRI, CT Angiograms, and ECG/EKG reports. These imaging studies are the absolute blueprint for any surgical planning.
Maintain a complete list of current prescription medications, particularly blood thinners (like Warfarin/Aspirin), as these must be carefully managed before any surgical intervention.
Keep a detailed symptom diary noting episodes of chest pain, fainting (syncope), severe shortness of breath when lying down, or "blue spells" in infants.
Ensure multiple family members are present for consultations, as cardiothoracic surgery involves highly complex risks, prolonged ICU stays, and intensive post-operative care discussions.

MS stands for Master of Surgery, and CVTS stands for Cardiovascular and Thoracic Surgery. This is the highest and most rigorous surgical degree available for operating on the heart and lungs. It signifies that Dr. Shahidullah has undergone years of intense, specialized training in utilizing heart-lung bypass machines and performing microscopic vascular surgery inside the beating or arrested human heart.
The aorta is the largest artery in the body, under massive pressure from the heart. When its inner lining tears (dissection), blood forces the layers of the artery apart. If it bursts completely, the patient bleeds to death internally in seconds. Alternatively, the tear can block blood flow to the brain (causing a massive stroke) or the heart itself (causing a fatal heart attack). Emergency surgery is the only way to replace the torn section.
It refers to severe congenital heart defects (like Tetralogy of Fallot or Transposition of the Great Arteries) where unoxygenated (blue) blood bypasses the lungs and is pumped directly back out to the body. This causes the baby's skin, lips, and nail beds to take on a terrifying bluish-purple tint (cyanosis). These conditions require major open-heart surgery to correct the plumbing of the heart.
Because the left side of the heart failed to grow during pregnancy, it cannot be "cured" to look like a normal four-chambered heart. However, it can be highly successfully palliated. Dr. Shahidullah and his team perform three separate open-heart surgeries over the child's first few years to reroute the blood vessels, forcing the right side of the heart to do the work of both sides, allowing the child to live and grow.
In TGA, the aorta and pulmonary artery are swapped. The surgical fix is a miraculous procedure called the Arterial Switch Operation, usually performed within the first few weeks of life. The surgeon cuts the two major arteries, switches them to their correct anatomical positions, and meticulously moves the microscopic coronary arteries (which feed the heart muscle) to the new aorta.
Standard endocarditis is treated with weeks of IV antibiotics. It becomes "complicated" and requires emergency open-heart surgery if the bacterial growths (vegetations) eat a hole through the heart valve causing sudden heart failure, if the infection spreads into the heart muscle causing an abscess, or if the clumps of bacteria threaten to break off and travel to the brain.
To operate on the delicate structures inside the heart, the surgeon needs the heart to be completely still and empty of blood. The heart-lung bypass machine temporarily takes over the job of the patient's heart (pumping blood) and lungs (adding oxygen). Tubes drain blood from the patient into the machine, which oxygenates it and pumps it back into the body, allowing Dr. Shahidullah to stop the heart safely during surgery.
No, "Tetralogy" means four. It involves four distinct defects: a hole between the ventricles (VSD), a narrowed pathway to the lungs (pulmonary stenosis), a thickened right heart muscle, and an aorta that sits over the hole. Surgical repair involves patching the hole shut and cutting away muscle/tissue to widen the pathway to the lungs, restoring normal, pink blood flow.
