Evaluating Sustained Ventricular Fibrillation Accurately

Dr. Rajan Bhatt is a longtime Scottsdale, Arizona, medical practitioner who leads medical practices such as Spectrum Dermatology & Vein Center. Extensively published in his field, Dr. Rajan Bhatt coauthored “Cardiac magnetic resonance imaging investigation of sustained ventricular fibrillation (VF) in a swine model-with a focus on the electrical phase” (Resuscitation, 2007).

This research aimed to develop a method for evaluating cardiac dimensions, which change quickly during sustained ventricular fibrillation (an irregular heartbeat impacting the heart’s ventricles). A primary obstacle to effective evaluation is the fact that conventional forms of cardiac magnetic resonance imaging (CMR) do not provide sufficient temporal resolution to accurately the capture dynamic changes that take place during VF’s early stages.

Dr. Bhatt hypothesized that measurable changes in the middle short axis slice of the ventricles would accurately reflect overall ventricular volume changes. His findings demonstrated that, over the course of half an hour of sustained VF, ventricular volume changes correlated closely with changes in the exact mid-slice area. This suggests that mid-slice area data works well as a surrogate marker of changes that occur to the heart during ventricular fibrillation.

Anesthesia Care Options at Valley Surgery Center

Dr. Rajan Bhatt is a Scottsdale, Arizona, physician who guides Spectrum Dermatology and leads Valley Surgery Center. When it comes to the latter multi-specialty facility, Dr. Rajan Bhatt emphasizes a team approach to anesthesia to ensure patient comfort.

This approach involves a certified nurse anesthetist and board certified anesthesiologist, who provide personalized care throughout surgery and other procedures. With type of surgery defining the anesthesia approach used, some patients only require local anesthetic that’s injected in the treated region. This numbs a localized area and blocks the nerves responsible for transmitting pain sensations.

Sedation typically takes the form of nitrous oxide which, in tandem with anesthesia, addresses patient anxieties as well as pain. More strong than the other two options, general anesthesia is administered intravenously and causes a temporary loss of consciousness. This is a safe, sleep-like state, which eliminates the pain that many people feel apprehensive about during surgery and related procedures.

Whatever anesthesia approach is selected, the aim is one of ensuring that the anesthetic applied is suitable for the actual procedure at hand, so that the patient can recover quickly once the surgery is completed. Your anesthesiologist will work closely with you, in tandem with a trusted physician, in recommending an anesthesia option ideally suited for the specific procedure at hand.

Prostate Cancer Treatment Benefits from Combined Therapies

Scottsdale, Arizona, physician Dr. Rajan Bhatt oversees locations such as Spectrum Dermatology & Vein Center, which provides wide-ranging, patient-centered care. Experienced in his field, Dr. Rajan Bhatt has given presentations on topics such as prostate cancer.

A study published in the Lancet in 2022 points to a newly developed, combined treatment therapy with the potential to boost survival rates for men with prostate cancer. A total of 1,792 participants enrolled in the study, including those who had previously had their prostates removed, and the patients were divided into three treatment groups.

Group one received salvage prostate bed radiotherapy (PBRT), a type of radiation that targets the area surrounding the prostate following its removal. Group two was administered the same PBRT regimen, as well as short-term androgen deprivation therapy (ADT). Group three received both PBRT and ADT, as well as pelvic lymph node radiotherapy (PLNRT), targeting the pelvic area’s lymph nodes, which can experience prostate cancer spread.

After 5 years, group three participants registered the greatest percentage of freedom from progression, with 87.4 percent meeting this criteria. By contrast, the percentage for group one members was only 71 percent. What this suggests is that the traditional PBRT standard of care can be amplified and intensified through related radiotherapies, with potentially life-saving results.
