Cardiologist Serving Katy, Sugar Land, Greater Houston
Temporary left ventricular (LV) support devices, such as the Impella heart pump and the intra-aortic balloon pump, help the heart circulate blood during a crisis or a high-risk procedure. They are placed and managed only in a hospital. Consultations and follow-up care take place at our Katy and Sugar Land offices.

LV support devices are used when the heart’s main pumping chamber, the left ventricle, cannot pump enough blood on its own, or when it may not be able to during a planned high-risk procedure. They provide temporary mechanical support, usually for hours to days, while the medical team treats the cause or plans the next step.
These devices are placed through an artery, usually in the groin, in a hospital catheterization laboratory or operating room, and patients are cared for in an intensive care or cardiac care unit while the device is in place. At Advanced Cardiology, Adnan Khalid, MD, whose listed specialties include interventional cardiology and advanced heart failure and transplant cardiology, evaluates patients, performs or coordinates device support at an affiliated hospital where appropriate, and provides follow-up care.

Mechanical circulatory support is not for everyone. It is considered in serious, usually hospital-based situations when the heart cannot maintain adequate circulation, and the decision is made by the hospital heart team based on each patient’s condition.
Why it matters: In cardiogenic shock, the heart cannot pump enough blood to meet the body’s needs, often after a large heart attack.
How support may help: A device can support blood pressure and circulation while the team treats the cause, such as opening a blocked artery. Research on survival benefit varies by device and situation, and these devices carry real risks, so their use is individualized.
Why it matters: Some patients with very weak heart function or complex coronary disease may become unstable during angioplasty and stenting.
How support may help: Temporary support may be used to help maintain blood flow during a complex procedure in selected patients.
Why it matters: A severely weakened heart may struggle during a sudden worsening of heart failure or after heart surgery.
How support may help: Reducing the heart’s workload can provide time for medicines and other treatment to work, or for the heart to recover.
Why it matters: Some patients with advanced heart failure are being evaluated for a durable LV assist device or heart transplant.
How support may help: Temporary support may stabilize a patient while those decisions are made at an advanced heart failure center.
It can:
While a device is in place, the ICU team closely monitors blood pressure, heart function on echocardiograms, kidney function, blood counts, and the device’s position. These measurements help decide when support can be reduced and removed.
It cannot:
A balloon pump assists the heart indirectly by changing pressure in the aorta and generally provides less support. An Impella pumps blood directly and can provide more support but may carry a higher risk of bleeding and blood vessel complications. The choice depends on how much support is needed, the patient’s blood vessels, and other factors.
Device placement happens in a hospital catheterization laboratory or operating room, often during an emergency. When there is time, the team explains the plan to the patient or family. Using X-ray and sometimes ultrasound guidance, the physician guides the device through an artery, usually in the groin and occasionally in the arm, into position. The patient is then cared for in an intensive care or cardiac care unit, usually lying fairly flat with the leg kept still to protect the access site. Blood thinners are typically given to prevent clots on the device, and the team checks circulation in the leg, kidney function, and blood counts regularly.
If temporary support is planned ahead of a high-risk procedure, follow the specific instructions your care team and the hospital give you. Some medicines, including blood thinners and diabetes medicines, may need to be adjusted, but only as directed; do not stop any medication on your own. Imaging of the leg arteries may be done first to check that they can accommodate the device.
These devices are used in very ill patients and carry significant risks, including bleeding, injury to the artery, reduced blood flow to the leg, damage to red blood cells, blood clots, stroke, infection, and device malfunction. Impella devices can also affect the aortic valve. The heart team weighs these risks against the expected benefit for each patient.
Recovery varies widely and depends mainly on the illness that required support. Some patients have the device removed within a day or two; others need longer support or further treatment. Hospital stays are often longer than for routine heart procedures, and cardiac rehabilitation is often part of recovery.
Is this the same as an LVAD? No. Impella and balloon pumps are temporary. A durable LVAD is implanted surgically for long-term support at specialized centers.
Can my loved one move while the device is in? Movement is usually limited to protect the device and access site. The nursing team will explain what is safe.
Who decides when it comes out? The hospital heart team, based on blood pressure, heart function, and how the body is responding.

Most decisions about temporary LV support are made in the hospital, often urgently. You or your family may discuss it with the heart team if:
In the office, Dr. Khalid can review your heart function, discuss whether a planned procedure might involve temporary support, and explain the options for advanced heart failure care or a low ejection fraction.
Call 911 for chest discomfort that lasts more than a few minutes or comes and goes, severe shortness of breath, fainting, confusion, cold and clammy skin, or stroke signs such as face drooping, arm weakness, or speech difficulty. These need emergency care, not an office appointment.
Most major insurance plans are accepted, and coverage is verified individually. LV support devices are used during hospital care, so hospital charges are billed separately. Our staff can help with questions about office visits and authorizations for planned procedures.
Temporary support helps the hospital team plan the next steps. Depending on how the heart responds, these may include:
After discharge, Dr. Khalid can follow your care at the Katy or Sugar Land office.

Blocked arteries in the heart are one of the most serious cardiovascular conditions affecting adults worldwide. This condition develops when fatty deposits called plaque build up inside the coronary arteries, gradually narrowing them and restricting blood flow to the heart muscle. Over time, reduced blood flow can cause chest pain, fatigue, breathing difficulties, and even […]
Sudden high blood pressure can feel alarming, especially if you were previously healthy or your readings were normal. Blood pressure can spike temporarily due to stress, lifestyle triggers, or underlying cardiovascular conditions. While occasional increases may not always be dangerous, repeated or very high spikes should never be ignored. Notes: In this blog, you will […]
Yes, acid reflux can sometimes feel very similar to a heart attack. Many people experience chest pain, burning sensations, tightness, and discomfort that can easily be mistaken for a cardiac emergency. This overlap in symptoms is one of the most common reasons patients visit emergency rooms for chest pain. Understanding the difference between acid reflux […]
Skipped heartbeats or heart fluttering are common sensations that many people experience at least once in their lifetime. They often feel like the heart pauses, flutters, or gives an extra beat. In most cases, these sensations are harmless. However, sometimes they may indicate an underlying heart rhythm disorder that requires medical evaluation. Notes: In this […]
Yes—anxiety can absolutely cause chest pain, chest tightness, and heart palpitations. These symptoms happen because stress activates the body’s “fight or flight” response, releasing hormones like adrenaline that increase heart rate and muscle tension. While anxiety-related chest discomfort is usually not dangerous, it can feel very similar to heart problems. That’s why it is important […]
Early signs of heart failure often develop slowly and may be mistaken for normal aging, stress, or fatigue. However, heart failure is a serious condition where the heart cannot pump blood effectively, leading to fluid buildup and reduced oxygen delivery to the body. Recognizing symptoms early can help prevent complications and improve long-term heart health. […]
