Eight days after starting mirtazapine, while still within the therapeutic window before the onset of the full action of the antidepressant, the patient was discussed at a case conference with the transplant cardiologists. At the meeting, the benefits and risks of ketamine were presented to the medical group, with a proposal to administer it to the patient, which was approved. The reasons for deciding on this option for the patient were the persistence of suicidal risk, the rapid onset of the antidepressant action of ketamine compared to antidepressants, and the ease of application and monitoring of the patient as he was already in a hospital environment.</p></span><span id="sec0050" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0110">Pre-procedure assessment for appropriate ketamine administration</span><p id="par0060" class="elsevierStylePara elsevierViewall">In 2017 Sanacora et al.<a class="elsevierStyleCrossRef" href="#bib0085"><span class="elsevierStyleSup">17</span></a> published a consensus document on ketamine for the treatment of affective disorders, which includes seven recommendations for the assessment of the candidate before infusion of the drug. <a class="elsevierStyleCrossRef" href="#tbl0005">Table 1</a> shows the assessment carried out on the patient.</p><elsevierMultimedia ident="tbl0005"></elsevierMultimedia></span><span id="sec0055" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0115">Anaesthetics</span><p id="par0065" class="elsevierStylePara elsevierViewall">Liaison Psychiatry made a referral to the Anaesthetics department to request support in the infusion of ketamine to a patient recently having had a heart transplant. Working together, we found systematic reviews and meta-analyses which enabled us to identify various doses of ketamine administration (from 0.5 to 7.0 mg/kg) and infusion frequencies (single, 1–3 times per week, once a month).<a class="elsevierStyleCrossRefs" href="#bib0090"><span class="elsevierStyleSup">18,19</span></a> In other clinical settings, continuous ketamine drips are common, such as in intensive care for sedation/analgesia,<a class="elsevierStyleCrossRef" href="#bib0100"><span class="elsevierStyleSup">20</span></a> on hospital wards to treat acute<a class="elsevierStyleCrossRef" href="#bib0105"><span class="elsevierStyleSup">21</span></a> and chronic pain,<a class="elsevierStyleCrossRef" href="#bib0110"><span class="elsevierStyleSup">22</span></a> and in Accident and Emergency departments for pain and as an alternative to opioids.<a class="elsevierStyleCrossRef" href="#bib0115"><span class="elsevierStyleSup">23</span></a></p><p id="par0070" class="elsevierStylePara elsevierViewall">In a recent systematic review and meta-analysis<a class="elsevierStyleCrossRef" href="#bib0120"><span class="elsevierStyleSup">24</span></a> which included 28 studies in the systematic review and 19 in the meta-analysis, nine studies were identified that assessed the effects of multiple infusions of 0.5 mg/kg of ketamine in 269 participants. No studies with continuous ketamine infusion were identified. According to the consensus for the use of ketamine in affective disorders,<a class="elsevierStyleCrossRef" href="#bib0085"><span class="elsevierStyleSup">17</span></a> the most frequently administered antidepressant dose in clinical studies with ketamine is 0.5 mg/kg in venous infusion over 40 min,<a class="elsevierStyleCrossRef" href="#bib0125"><span class="elsevierStyleSup">25</span></a> which does not produce anaesthetic effects. However, an average increase of 13.4 mmHg<a class="elsevierStyleCrossRef" href="#bib0045"><span class="elsevierStyleSup">9</span></a> in systolic pressure has been reported, with BP values of 180/100 mmHg or heart rates >110 bpm in 30% of treated patients.</p><p id="par0075" class="elsevierStylePara elsevierViewall">The use of ketamine infusion for depression has been associated with the following side effects<a class="elsevierStyleCrossRefs" href="#bib0130"><span class="elsevierStyleSup">26,27</span></a>: psychiatric in 72% of studies assessing it (anxiety, agitation, irritability, delusions, panic, derealisation, depersonalisation); cardiovascular in 38% (increased blood pressure, arrhythmias, palpitations, chest pain, increased heart rate); neurological (headache, dizziness, poor motor coordination, tremor and involuntary movements); and in other systems (gastrointestinal, respiratory, urological, ocular). Consequently, in addition to the particular situation of our patient (heart transplant) and the fact that we were unable to find any reported cases in similar patients, the Anaesthetics department proposed a total dose of 90 mg of ketamine diluted in 250 ml of 0.9% saline solution to infuse over 25 h at a rate of 10 ml/h, which provided ketamine 1.5 mg/kg body weight.

On the day of the ketamine infusion, just beforehand, a conversation was held with the patient and his wife about the previous day's conversation. The patient's understanding of the clinical situation was verified, doubts were resolved, and informed consent was signed. The patient's weight and height were checked (60 kg and 170 cm; body mass index, 20.7). The patient's vital signs were taken and he was asked to lie down on the bed. The ketamine infusion was administered through a venous catheter in his left forearm. His initial blood pressure was 130/85 mmHg; heart rate, 72 bpm; respiratory rate, 14 rpm; and temperature, 36.5°C.

His wife said she saw him in very good spirits, smiling, with spontaneous displays of affection towards her and the children, spontaneously talking about returning home and showing affection through hugs and kisses to his family members.</p></span><span id="sec0075" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0135">Changes in the PHQ-9 score after the infusion</span><p id="par0095" class="elsevierStylePara elsevierViewall">The PHQ-9 prior to ketamine infusion was 20.

The psychiatry resident (MMA) called him every eight days to conduct the hospital follow-up. The telephone interview was semi-structured. First, the patient was asked about personal and family events during the last week, and then a check was made on mood and associated cognitive functions. He was then asked to complete the PHQ-9 and send it in via his mobile phone. The patient continues to take mirtazapine 30 mg orally every night.</p><p id="par0110" class="elsevierStylePara elsevierViewall">His wife reported by telephone that her husband continues to be in good spirits, is more physically active, does household activities, is in a better mood, makes jokes, starts conversations spontaneously, sleeps well, has a better appetite, and is making plans for the future. The follow-up continued in this form for the next 12 weeks, with affective stability and persistence of euthymia observed. Eleven months after the ketamine infusion, the patient continues on treatment with mirtazapine 30 mg/night. He says he feels in good spirits, able to enjoy his daily activities and without suicidal thoughts. His wife and children see him in better spirits and with more physically active during the day. The transplant cardiologist describes an overall clinical improvement, including improvement in mood.</p></span></span><span id="sec0090" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0150">Discussion</span><p id="par0115" class="elsevierStylePara elsevierViewall">The admission of a patient with deep vein thrombosis and pulmonary embolism, which subsequently generated cardiac hypokinesis and put the patient's life at risk, was the indirect consequence of symptoms such as sadness, anhedonia, anergy and a sedentary lifestyle in a heart transplant patient with comorbid severe depression.</p><p id="par0120" class="elsevierStylePara elsevierViewall">In transplant patients, major depression doubles the risk of graft rejection and post-transplant mortality,<a class="elsevierStyleCrossRefs" href="#bib0145"><span class="elsevierStyleSup">29,30</span></a> in addition to reducing heart rate variability and contributing to the development of deep vein thrombosis, as occurred in our patient.<a class="elsevierStyleCrossRef" href="#bib0155"><span class="elsevierStyleSup">31</span></a> The symptoms of depression are often confused with those generated by immunosuppressive medications, such as insomnia, anergy, difficulty concentrating and anorexia, but other symptoms such as hopelessness and suicidal ideation are not considered part of the normal trajectory of the post-transplant patient.<a class="elsevierStyleCrossRef" href="#bib0160"><span class="elsevierStyleSup">32</span></a></p><p id="par0125" class="elsevierStylePara elsevierViewall">Depression is a medical disorder for which there are numerous pharmacological and psychotherapeutic interventions available, but most antidepressant medications take between two and six weeks to begin their therapeutic effect.

This indication is based on the rapid and powerful antidepressant effect. Typical dosing regimens for ketamine in these cases are sub-anaesthetic doses of 0.5 mg/kg in 40 min of infusion. This case report is novel in two aspects: first, it concerns a heart transplant patient and second, the dose used has not been reported before and shows a robust and positive antidepressant effect.</p><p id="par0135" class="elsevierStylePara elsevierViewall">Irwin et al.<a class="elsevierStyleCrossRef" href="#bib0165"><span class="elsevierStyleSup">33</span></a> reported two cases of hospice patients, seriously ill with other clinical problems, who had rapid and persistent improvement in depression and anxiety after ketamine infusion.
