[Simultaneous heart and kidney transplantation using the same donor].

From 1988 to 1991, five cases of combined heart and kidney transplantation using the same donor have been achieved at our institution. All patients were males, 58 +/- 6 (46 to 64). The cardiac condition leading to the cardiac replacement was a dilated cardiomyopathy in one case, end-stage ischemic disease in 3, and failure of a previous cardiac transplantation in one. The renal condition claiming for a graft was a Glomerular nephritis in one, a polycystic disease in 3, and renal failure due to CyA toxicity in one; chronic hemodialysis was mandatory in all patients but one. There were no hospital deaths. The five patients are current survivors, the mean follow-up being 22 +/- 10 months (2-50 months). Five rejection episodes occurred in three patients; two patients have never demonstrated any cardiac rejection. All but one recovered a normal renal function as soon as the 7 th post operative day; only one episode of renal rejection has been detected, easily reversed by corticoids. No simultaneity was ever observed between cardiac and renal rejection episodes. Thus, the detection of rejection must be carried out separately for each graft organ. In four patients, cineangiograms of the coronary vessels were done respectively 12, 30 and 50 months post operatively and revealed a normal coronary bed. Thus, combined heart and kidney transplantation seems to be a realistic approach in properly selected patients in whom cardiac and renal failures cannot be treated by more conventional procedures.

[Artificial hearts. The experience of Henri Mondor University Hospital].

Results obtained with 52 patients referred for urgent heart transplantation or when transplantation was impossible because no graft, mechanical assistance or circulatory support were available, are reported. These suggest that the protocol used to select the indications of assistance and transplantation, based on the response to the introduction of enoximone into the medical treatment, allows reconciling the patients' interest-their survival-with the community's interest-i.e. the control of the costs of implemented treatments.

[Emergency aorto-coronary bypass after myocardial infarction].

During a recent three-year period, 37 patients had an emergent aortocoronary bypass (ACB) after evolutive acute myocardial infarction. The patients are divided up into two groups: group I includes 12 patients who were operated after the failure of early thrombolysis; group II includes 25 patients operated after the failure of revascularization through percutaneous angioplasty. In group I, all patients survived and 9 had no postoperative complications. In group II, the outcome was favorable for 16 patients. Long-lasting postoperative inotropic support was required for nine patients. Two patients died early. In all patients of the study, surgery failed to prevent myocardial necrosis but there was no recurrence of angina nor major left ventricular malfunction in the long term. This work suggests that early surgery after acute myocardial infarction may be a rescue procedure, with low risks and good long-term results.

[Can solid state Holter monitoring replace endomyocardial biopsy in patients with heart transplantation?].

Acute cardiac graft rejection after transplantation, the diagnosis of which is based on the findings of endomyocardial biopsy, is associated with a reduction in coronary reserve due to abnormalities of the microcirculation. But this reduction in coronary reserve cause silent myocardial ischaemia (SMI)? In order to assess the frequency of SMI and ventricular arrhythmias during rejection, 53 consecutive Holter recordings were performed in 32 patients (28 men, 4 women, average age 47 +/- 11 years) 11 months after transplantation and within 24 hours of endomyocardial biopsy. The recorder which was used (Monitor One TC) analysed the ST segment in 2 leads in real time: ST segment depression of more than 1 mm lasting over 40 ms, 0.08 s after the J point were considered to be diagnostic of myocardial ischaemia. Although the frequency of SMI is low and not specific for cardiac rejection, its duration was twice as long (80 mn vs 38 mn) in this condition. On the other hand, ventricular arrhythmias are common in cardiac rejection and correlated with its severity according to Billingham's classification (VES p = 0.045; doublets p = 0.035; non-sustained VT p = 0.006).

[Reduction of per- and postoperative blood loss with aprotinin (Trasylol) during extracorporeal circulation].

Aprotinin is a pharmacological agent which, when given in high doses during cardiopulmonary bypass (CPB), seems to reduce postoperative blood loss significantly and thereby reduces the need for blood transfusion. This study was undertaken to confirm these claims and to show that there was also decreased peroperative bleeding and a shorter operation time. The immediate postoperative clinical course was also assessed. The study was a prospective, randomised double-blind trial versus placebo in 60 coronary patients undergoing at least 2 aorto-coronary bypass grafts for the first time within a 3 month period. During surgery after stopping the CPB the blood loss recorded by aspiration was 49 +/- 61 ml in the aprotinin group and 90 +/- 84 ml in the placebo group (p less than 0.05). The quality of haemostasis in the operated area evaluated independently by the anaesthetist was judged to be excellent in 30 patients in the aprotinin group compared with only 19 in the placebo group (p less than 0.001). The time between coming off CPB and skin closure was significantly shorter in the aprotinin group (42 +/- 10 min versus 49 +/- 12 min) and the dose of protamine injected at the end of the operation was 19 +/- 38 mg in the aprotinin group compared to 43 +/- 46 mg in the placebo group (p less than 0.05). The blood loss recorded over 48 hours in the intensive care unit was nearly three times less in the aprotinin group (380 +/- 125 ml) than with placebo (852 +/- 523 ml).(ABSTRACT TRUNCATED AT 250 WORDS)

[Heart transplantation in acute myocardial infarction].

Ten patients with cardiogenic shock after acute myocardial infarction were referred to the University Hospital Henri Mondor as candidates for cardiac transplantation. The period before transplantation was bridged by maximal pharmacological support including sympathomimetic and phosphodiesterase inhibitor inotropic agents and, in non-responders, by mechanical ventricular assist devices (1 case) or artificial hearts (2 cases). The 7 patients who improved with optimal pharmacological support alone had a good initial course. However, only two of these patients were finally transplanted, three died suddenly either in the intensive care unit or after withdrawal of intravenous drugs and hospital discharge. One patient remained well and after coronary bypass surgery, enjoys good quality life. One patient was found secondarily to be a poor candidate for transplantation and died shortly after. The outcome of 2 of the 3 patients who did not respond to pharmacological treatment and who required mechanical support was spectacularly good and enabled successful cardiac transplantation. Our experience underlines the numerous difficulties of different natures of cardiac transplantation in this indication, the value and risks of the new inotropic agents, and the real but limited role of heroic procedures such as the artificial heart.

Irreversible drop of systemic vascular resistances in patients implanted with a Jarvik total artificial heart.

Maintenance of the body's perfusion by a total artificial heart (TAH) may result in physiological alterations to the circulatory system. Little has been said about modifications to systemic vascular resistances (SVR) during TAH assistance. This paper reports on two patients implanted with a Jarvik - 70 cc TAH, who died after 1 and 3 days, both with an irreversible drop of SVR related to a complete loss of vascular tone but not related to sepsis. Activation of multiple cascades of inflammation, triggered by the extracorporeal circulation (ECC), is maintained during TAH support. Desperately sick patients might not be able to face the vaso-active situations created by the inflammatory response.

[Severe calcified aortic stenosis in patients aged 80 or older. Apropos of 65 cases surgically treated].

From 1981 to 1989, 65 patients over 80 years were submitted to surgery for severe calcific aortic stenosis. Thirteen patients were in NYHA II, 31 in NYHA III, 21 in NYHA IV. Mean valve area was 0.52 +/- 0.14 cm2 and mean aortic valve gradient was 62 +/- 18 mmHg. Left ventricular function was altered (ejection fraction less than 40%) in 33 patients. Six patients had a previous balloon aortic valvuloplasty. Bioprosthesis were used in all 65 patients associated to CABG (in 5) and mitral valve replacement (in 1). One month mortality was 19 cases (29%) due to cardiac failure (in 10) pulmonary (in 7) and neurological (in only 2) complications. Early mortality was nearly significantly correlated to NYHA stage (p = 0.08) and preop renal insufficiency (p = 0.07). It was significantly correlated to function (40% mortality when ejection fraction less than 40%, 16% in others) and to operations on emergency basis (5 deaths over 6). Hospital morbidity was 68%. There were 5 late deaths. Among the 41 long-term survivors (3 mths-7yrs) 29 are in NYHA I, 10 in NYHA II and 2 in NYHA III due to valve failure. The actuarial survival probability is 65% at one year, 50% at 5 years. In summary good long-term results justify to take a high post operative risk in octogenarians. Early surgery before left ventricular impairment improves the survival.

Severe aortic stenosis in octogenarians: is operation an acceptable alternative?

From 1981 to 1989, 60 patients more than 80 years of age were referred for operation for severe calcific aortic stenosis. All patients were symptomatic: 13 in New York Heart Association (NYHA) functional class II, 28 in class III, and 19 in class IV. The preoperative mean cardiothoracic ratio was 0.58 +/- 0.09; the mean valve area, 0.52 +/- 0.14 cm2; and the mean aortic valve gradient, 62 +/- 18 mm Hg. Left ventricular function was impaired in 30 patients (ejection fraction less than 0.40). Coronary arteriography was performed in 10 patients. Aortic replacement used bioprosthesis in all 60 patients associated with aortocoronary bypass (in 5) and mitral valve replacement (in 1). One-month mortality rate was 28% (17 patients) due to cardiac failure (in 9), pulmonary complications (in 6), and neurological complications (in 2). Early mortality was not correlated with preoperative angina, cardiothoracic ratio, associated operation, and cross-clamping time. It was not obviously correlated with preoperative functional class but correlated positively with urgent operations and with left ventricular function (40% mortality in patients with ejection fraction less than 0.40 versus 16% mortality in others). Hospital morbidity was 68%. Mean hospitalization was 15 +/- 7 days. There were four late deaths. Thirty-nine patients are long-term survivors (3 months to 7 years): 27 in class I, 10 in class II, and 2 in class III due to primary valve failure. The actuarial survival probability is 65% at 1 year and 61% at 5 years. In summary, the good long-term quality of life justifies the high postoperative risk in octogenarians. Early operation before cardiac function impairment improves the results.

Are there indications for reconstructive surgery in severe mitral regurgitation after acute myocardial infarction?

From 1972 to 1988, early surgery were performed in 26 patients with acute mitral regurgitation (MR) unresponsive to medical management complicating a recent acute myocardial infarction (AMI). The indication was acute pulmonary oedema (11), major left ventricular insufficiency (5), cardiogenic shock (10). Surgery was performed within 3 weeks following AMI. Mitral lesions were as follows: rupture of chordae tendinae (9) of papillary muscle (6), haemorrhagic necrosis of one (17) or two (9) papillary muscles. The mitral annulus was never found to be enlarged. The LV posterior wall was necrotic in 23, with a septal rupture in 3 and a giant aneurysm in 5. Valve replacement was performed in all but one patient. The 30-day mortality included 8 patients (31%). The cause of death was myocardial insufficiency in 5, early thrombosis of a disk valve in 1 and unrelated complications in 2. One patient deteriorated rapidly and had a Jarvik device implanted. Late results (1 month-15 years) showed 4 cardiac related deaths within the first year. One patient had to be transplanted after 1 year. Two patients died of non-cardiac problems at 3 months and 5 years. The probability of survival at 5 years is 43% and at 10 years 22%. In conclusion, there are still indications for early surgery in MR post AMI. Anatomical lesions of both papillary muscles and ventricular wall do not allow conservative surgery and new non-invasive technics provide a more promising strategy in such desperately ill patients.

[Use of brachial venous grafts in coronary bypass surgery].

From May, 1975, to December, 1988, 30 patients (pts), 26 men and 4 women, aged 36 to 79 (average age: 58) underwent one or several aortocoronary bypass (ACB) operations requiring the use of veins from the upper limbs (VUL). Sixty operations (2.0 ACB/pt) were performed, involving the anterior interventricular artery in 27 cases, the right coronary artery in 14 and the other left vessels in 19. The grafts used were a VUL in 45 cases, an internal mammary artery in 13, a great saphenous vein in one case and a 4-mm polyurethan tube in one case. The indications for the use of a VUL included bilateral stripping in 23 patients, repeated phlebitis in one, bilateral varices in 2, and the previous use of the saphenous veins in 4 patients. The coronary lesions were a three-vessel involvement in 17 cases, a two-vessel involvement in 9 and a single-vessel involvement in 4. An additional procedure was required in two patients for the resection of a left ventricular aneurysm and for the plication of an akinetic area of the left ventricle. No intraoperative complication was observed. Perioperative mortality was of two cases (6.6%). The postoperative myocardial infarction rate was of one case (3.3%). A complication directly associated with the type of graft used (massive bleeding due to graft tearing) caused cardiac arrest in one case. Two patients presented with local disorders caused by the removal of veins from the upper limbs, including hypoesthesia of the forearm in one case and anesthesia associated with regressive muscle enfeeblement in the other.(ABSTRACT TRUNCATED AT 250 WORDS)

Pharmacological bridge to cardiac transplantation.

From September 1985 to August 1988, 32 patients were referred from various intensive care units throughout Paris for urgent cardiac transplantation or for a mechanical bridge to transplantation. At time of admission, under maximal sympathomimetic therapy, the cardiac index (CI) was 1.81 +/- 0.26 l/min per m2, the pulmonary capillary wedge pressure (PCWP 31 +/- 7 mmHg), systemic vascular resistances (SVR) 2053 +/- 469 dynes s cm-5. In 25, diuresis was less than 25 ml/h. Five were anuric. Prior to any final decision, a new inotropic agent, enoximone, was infused in addition to previous treatment as a 10 min bolus iv 1.5-2 mg/kg every 8 h. In 3, the situation further deteriorated, leading to a Jarvik 7-70 implantation within 12 h. In 29 however, within 3 h, the Cl increased to 2.69 +/- 0.56 as SVR dropped to 1410 +/- 453 and PCWP to 18 +/- 7. Diuresis increased to more than 100 ml/h in all. This permitted an indepth evaluation of the transplant candidates leading to contraindications to transplantation in 16. Nine patients could be weaned off iv enoximone. Four of these are still living (NYHA class III) with a follow up of 6-17 months. In 11, transplantation was performed within 2 days. Four died within a month, 2 with multiple organ failure. One patient died after 5 months. Six are back to normal life, NYHA class I (follow up 10 months-2.5 years). This protocol suggests that in patients with extreme heart failure, immediate survival may be increased by iv enoximone therapy, permitting a better selection of the recipients, more efficient pre-transplantation intensive care and consequently a decrease in the indications for a temporary mechanical bridge to a staged transplantation.

Combined heart and kidney transplantation using the same donor.

A 45-year-old man received a combined heart and kidney transplant provided by the same donor. The patient was in the terminal stage of renal failure and was submitted to 3 sessions of haemodialysis per week for 2 years before transplantation. A dilated cardiomyopathy with severe impairment of left ventricular (LV) function was discovered, precluding renal transplantation alone. In the postoperative course, a cardiac rejection episode was detected by echocardiography and documented by endomyocardial biopsy; no simultaneous rejection of the kidney could be detected. The patient was discharged after 2 months, and he resumed a normal and active life. The specific problems raised by the management of such multi-organ transplantation are briefly reviewed.

Acute Budd-Chiari syndrome secondary to leiomyosarcoma of the inferior vena cava.

The authors report a case of leiomyosarcoma of the inferior vena cava, responsible for an acute Budd-Chiari syndrome. The diagnosis, suggested by lower limb edema, ascites, and renal failure, was confirmed by sonography, CT scan, and pathological examination. A mesoatrial shunt and right atrial thrombectomy were performed under extracorporeal circulation. The inferior vena cava was ligated because the tumor was considered to be unresectable.

The mitroflow pericardial valve. First results of a follow-up study.

One hundred eighty-eight Mitroflow pericardial valves, implanted on 166 patients from March 1983 to December 1986, have been followed for a total of 4316 patients x months. Mortality rate in the first three postoperative months is approximately 10% related to noncardiac complications. One hundred forty-nine patients are living at the start of the follow up period. During that period, one valve was explanted after 22 months for a cusp tear. The rate of thrombo embolic episode is minimal, six cases, as 47% are free of any anticoagulant therapy. One patient, operated upon for active SBE, required additional surgery 2 months later for a prosthetic infection. The present results suggest that early primary failure of Mitroflow valve is quite unfrequent.

Echocardiographic demonstration of intracardiac glue after endoscopic obturation of gastroesophageal varices.

Systemic embolism is an unusual complication of endoscopic obturation of gastroesophageal varices with glue. This report describes a case of cerebral embolism after this procedure. Intracardiac glue within the left atrium was demonstrated by echocardiography. Cardiac fluoroscopy demonstrated an abnormal vessel connecting periesophageal veins with the right upper pulmonary vein. Cardiac surgery was performed. Intracardiac glue was removed and the entering orifice of the abnormal vessel in the right upper pulmonary vein was sutured. To our knowledge, this is the first reported case of intracardiac glue after variceal obturation. Echocardiography is useful in the diagnosis of this rare complication.
