Dr. Keiichi Itatani, an Adult Congenital Heart Surgeon and Founder of Blood Flow Analysis, is Here to Adress Your Heart -Related Concerns

This service is primarily intended for individuals who underwent heart surgery during childhood and are now experiencing concerns—whether during adolescence or adulthood—regarding their condition. Examples include those who had surgery for Tetralogy of Fallot and were told they might require a reoperation in adulthood (but are unsure where to seek such care), individuals who underwent a Fontan procedure as children, those who are repeatedly told during annual check-ups that they have a heart murmur or potential valvular heart disease, or anyone else seeking a second opinion related to adult congenital heart disease (ACHD). We particularly recommend this to those who wish to undergo surgical treatment in Japan.

The appropriate timing and destination for a transfer depend on the type of illness and your current condition. In many cases, coordination with your current healthcare provider is necessary, so please consult with us.

The precautions to take vary depending on the condition of your heart and blood vessels. I can provide specific guidance, as well as advice on how best to approach discussions with your primary physician.

Whether or not you can engage in work or physical exercise depends on your specific medical condition. Even if you feel no symptoms while at rest, physical activity or labor can place a strain on your heart; in some cases, undergoing surgery can enable a person to return to work safely. We are available to discuss your specific situation, as well as how best to approach these matters with your primary physician.

There is no charge. Online consultations are available free of charge, with each session lasting 30 minutes.

You may choose between two consultation methods—email-based consultation or online consultation (via Zoom)—when submitting your request. Please note that, depending on appointment availability or the nature of your inquiry, we may provide our response via email even if you have requested an online consultation.

The details of your consultation and your name will not be disclosed to your attending physician or any third party without your consent. We believe that seeking an additional, professional opinion—while maintaining a positive relationship with your current attending physician—is a fundamental right of every patient.

This consultation service does not provide medical procedures, such as definitive diagnoses, the prescription of medication, or emergency care. We also do not perform formal interpretations of medical imaging or test data. If necessary, we will direct you to seek care at a medical institution or at the Juntendo ACHD (Adult Congenital Heart Disease) outpatient clinic.

Due to limited appointment availability, we generally restrict each person to a single session. If we determine it is necessary, we will advise you to seek a consultation at a medical facility.

As this is an online consultation, you can access it from anywhere.

We also accept inquiries from family members. Please indicate your relationship to the individual concerned using the application form.

Please provide whatever information you have on hand; a referral letter is not required for a consultation. We can also offer guidance on how to approach discussions with your primary physician, should the need arise.

We are available for consultations regarding potential patient referrals, current treatment approaches, specialized diagnostic testing, or surgical interventions.
